The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +1.1 Quick configuration advice +============================== + +If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +1.2 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the included GNU +`gettext' library will be used. This library is wholly contained +within this package, usually in the `intl/' subdirectory, so prior +installation of the GNU `gettext' package is _not_ required. +Installers may use special options at configuration time for changing +the default behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will, respectively, bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might not be desirable. You should use +the more recent version of the GNU `gettext' library. I.e. if the file +`intl/VERSION' shows that the library which comes with this package is +more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.3 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, +and `CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.4 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" +area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `translation@iro.umontreal.ca' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skill are praised more than +programming skill, here. + +1.5 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of July +2006. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am ar

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`translation@iro.umontreal.ca' to make the `.pot' files available to +the translation teams. + diff --git a/AUTHORS b/AUTHORS new file mode 100644 index 0000000..0a3ca6f --- /dev/null +++ b/AUTHORS @@ -0,0 +1,8 @@ +Authors of GNU Bison. + +Bison was written primarily by Robert Corbett. + +Richard Stallman made it Yacc-compatible. + +Wilfred Hansen of Carnegie Mellon University added multicharacter +string literals and other features. diff --git a/COPYING b/COPYING new file mode 100644 index 0000000..94a9ed0 --- /dev/null +++ b/COPYING @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

Denny + + * src/lalr.c (state_lookahead_tokens_count): For code readability, + move the check for disabled transitions to an aver since conflict + resolution hasn't happened yet. + + * src/lalr.c (state_lookahead_tokens_count): Remove the check that + labels a state as inconsistent just because it has error transitions. + The original form of this check appeared in revision 1.1 of lalr.c, + which was committed on 1991-12-21. Now (at least), changing the + consistency label on such a state appears to have no useful effect in + any of the places it is examined, which I enumerate below. The key + point to understanding each item in this enumeration is that a state + with an error transition is labelled consistent in the first place only + if it has no rules, so the check cannot matter for states that have + rules. (1) Labelling a state as inconsistent will cause set_conflicts + to try to identify its conflicts, and a state must have *rules* to have + conflicts. (2) Labelling a state as inconsistent will affect how + action_row sets the default *rule* for the state. (3) Labelling a + state as inconsistent will cause build_relations to add lookback edges + to *rules* in that state. + * src/state.h (struct state): Word the comment for member consistent + more carefully. + +2007-05-27 Joel E.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..932c3bb --- /dev/null +++ b/Makefile.am @@ -0,0 +1,59 @@ +## Process this file with automake to produce Makefile.in -*-Makefile-*- +## Copyright (C) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 Free Software +## Foundation, Inc. + +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This allowed actions such as + + exp: exp "+" exp { $$ = $1 + $3 }; + + instead of + + exp: exp "+" exp { $$ = $1 + $3; }; + + Some grammars still depend on this `feature'. Bison 2.4.1 restores + the previous behavior in the case of C output (specifically, when + neither %language or %skeleton or equivalent command-line options + are used) to leave more time for grammars depending on the old + behavior to be adjusted. Future releases of Bison will disable this + feature. + +** A few minor improvements to the Bison manual. + +* Changes in version 2.4 (2008-11-02): + +** %language is an experimental feature. + + We first introduced this feature in test release 2.3b as a cleaner + alternative to %skeleton. Since then, we have discussed the possibility of + modifying its effect on Bison's output file names. Thus, in this release, + we consider %language to be an experimental feature that will likely evolve + in future releases. + +** Forward compatibility with GNU M4 has been improved. + +** Several bugs in the C++ skeleton and the experimental Java skeleton have been + fixed. + +* Changes in version 2.3b (2008-05-27): + +** The quotes around NAME that used to be required in the following directive + are now deprecated: + + %define NAME "VALUE" + +** The directive `%pure-parser' is now deprecated in favor of: + + %define api.pure + + which has the same effect except that Bison is more careful to warn about + unreasonable usage in the latter case. + +** Push Parsing + + Bison can now generate an LALR(1) parser in C with a push interface. That + is, instead of invoking `yyparse', which pulls tokens from `yylex', you can + push one token at a time to the parser using `yypush_parse', which will + return to the caller after processing each token. By default, the push + interface is disabled. Either of the following directives will enable it: + + %define api.push_pull "push" // Just push; does not require yylex. + %define api.push_pull "both" // Push and pull; requires yylex. + + See the new section `A Push Parser' in the Bison manual for details. + + The current push parsing interface is experimental and may evolve. More user + feedback will help to stabilize it. + +** The -g and --graph options now output graphs in Graphviz DOT format, + not VCG format. Like --graph, -g now also takes an optional FILE argument + and thus cannot be bundled with other short options. + +** Java + + Bison can now generate an LALR(1) parser in Java. The skeleton is + `data/lalr1.java'. Consider using the new %language directive instead of + %skeleton to select it. + + See the new section `Java Parsers' in the Bison manual for details. + + The current Java interface is experimental and may evolve. More user + feedback will help to stabilize it. + +** %language + + This new directive specifies the programming language of the generated + parser, which can be C (the default), C++, or Java. Besides the skeleton + that Bison uses, the directive affects the names of the generated files if + the grammar file's name ends in ".y". + +** XML Automaton Report + + Bison can now generate an XML report of the LALR(1) automaton using the new + `--xml' option. The current XML schema is experimental and may evolve. More + user feedback will help to stabilize it. + +** The grammar file may now specify the name of the parser header file using + %defines. For example: + + %defines "parser.h" + +** When reporting useless rules, useless nonterminals, and unused terminals, + Bison now employs the terms "useless in grammar" instead of "useless", + "useless in parser" instead of "never reduced", and "unused in grammar" + instead of "unused". + +** Unreachable State Removal + + Previously, Bison sometimes generated parser tables containing unreachable + states. A state can become unreachable during conflict resolution if Bison + disables a shift action leading to it from a predecessor state. Bison now: + + 1. Removes unreachable states. + + 2. Does not report any conflicts that appeared in unreachable states. + WARNING: As a result, you may need to update %expect and %expect-rr + directives in existing grammar files. + + 3. For any rule used only in such states, Bison now reports the rule as + "useless in parser due to conflicts". + + This feature can be disabled with the following directive: + + %define lr.keep_unreachable_states + + See the %define entry in the `Bison Declaration Summary' in the Bison manual + for further discussion. + +** Lookahead Set Correction in the `.output' Report + + When instructed to generate a `.output' file including lookahead sets + (using `--report=lookahead', for example), Bison now prints each reduction's + lookahead set only next to the associated state's one item that (1) is + associated with the same rule as the reduction and (2) has its dot at the end + of its RHS. Previously, Bison also erroneously printed the lookahead set + next to all of the state's other items associated with the same rule. This + bug affected only the `.output' file and not the generated parser source + code. + +** --report-file=FILE is a new option to override the default `.output' file + name. + +** The `=' that used to be required in the following directives is now + deprecated: + + %file-prefix "parser" + %name-prefix "c_" + %output "parser.c" + +** An Alternative to `%{...%}' -- `%code QUALIFIER {CODE}' + + Bison 2.3a provided a new set of directives as a more flexible alternative to + the traditional Yacc prologue blocks. Those have now been consolidated into + a single %code directive with an optional qualifier field, which identifies + the purpose of the code and thus the location(s) where Bison should generate + it: + + 1. `%code {CODE}' replaces `%after-header {CODE}' + 2. `%code requires {CODE}' replaces `%start-header {CODE}' + 3. `%code provides {CODE}' replaces `%end-header {CODE}' + 4. `%code top {CODE}' replaces `%before-header {CODE}' + + See the %code entries in section `Bison Declaration Summary' in the Bison + manual for a summary of the new functionality. See the new section `Prologue + Alternatives' for a detailed discussion including the advantages of %code + over the traditional Yacc prologues. + + The prologue alternatives are experimental. More user feedback will help to + determine whether they should become permanent features. + +** Revised warning: unset or unused mid-rule values + + Since Bison 2.2, Bison has warned about mid-rule values that are set but not + used within any of the actions of the parent rule. For example, Bison warns + about unused $2 in: + + exp: '1' { $$ = 1; } '+' exp { $$ = $1 + $4; }; + + Now, Bison also warns about mid-rule values that are used but not set. For + example, Bison warns about unset $$ in the mid-rule action in: + + exp: '1' { $1 = 1; } '+' exp { $$ = $2 + $4; }; + + However, Bison now disables both of these warnings by default since they + sometimes prove to be false alarms in existing grammars employing the Yacc + constructs $0 or $-N (where N is some positive integer). + + To enable these warnings, specify the option `--warnings=midrule-values' or + `-W', which is a synonym for `--warnings=all'. + +** Default %destructor or %printer with `<*>' or `<>' + + Bison now recognizes two separate kinds of default %destructor's and + %printer's: + + 1. Place `<*>' in a %destructor/%printer symbol list to define a default + %destructor/%printer for all grammar symbols for which you have formally + declared semantic type tags. + + 2. Place `<>' in a %destructor/%printer symbol list to define a default + %destructor/%printer for all grammar symbols without declared semantic + type tags. + + Bison no longer supports the `%symbol-default' notation from Bison 2.3a. + `<*>' and `<>' combined achieve the same effect with one exception: Bison no + longer applies any %destructor to a mid-rule value if that mid-rule value is + not actually ever referenced using either $$ or $n in a semantic action. + + The default %destructor's and %printer's are experimental. More user + feedback will help to determine whether they should become permanent + features. + + See the section `Freeing Discarded Symbols' in the Bison manual for further + details. + +** %left, %right, and %nonassoc can now declare token numbers. This is required + by POSIX. However, see the end of section `Operator Precedence' in the Bison + manual for a caveat concerning the treatment of literal strings. + +** The nonfunctional --no-parser, -n, and %no-parser options have been + completely removed from Bison. + +* Changes in version 2.3a, 2006-09-13: + +** Instead of %union, you can define and use your own union type + YYSTYPE if your grammar contains at least one tag. + Your YYSTYPE need not be a macro; it can be a typedef. + This change is for compatibility with other Yacc implementations, + and is required by POSIX. + +** Locations columns and lines start at 1. + In accordance with the GNU Coding Standards and Emacs. + +** You may now declare per-type and default %destructor's and %printer's: + + For example: + + %union { char *string; } + %token STRING1 + %token STRING2 + %type string1 + %type string2 + %union { char character; } + %token CHR + %type chr + %destructor { free ($$); } %symbol-default + %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1 + %destructor { } + + guarantees that, when the parser discards any user-defined symbol that has a + semantic type tag other than `', it passes its semantic value to + `free'. However, when the parser discards a `STRING1' or a `string1', it + also prints its line number to `stdout'. It performs only the second + `%destructor' in this case, so it invokes `free' only once. + + [Although we failed to mention this here in the 2.3a release, the default + %destructor's and %printer's were experimental, and they were rewritten in + future versions.] + +** Except for LALR(1) parsers in C with POSIX Yacc emulation enabled (with `-y', + `--yacc', or `%yacc'), Bison no longer generates #define statements for + associating token numbers with token names. Removing the #define statements + helps to sanitize the global namespace during preprocessing, but POSIX Yacc + requires them. Bison still generates an enum for token names in all cases. + +** Handling of traditional Yacc prologue blocks is now more consistent but + potentially incompatible with previous releases of Bison. + + As before, you declare prologue blocks in your grammar file with the + `%{ ... %}' syntax. To generate the pre-prologue, Bison concatenates all + prologue blocks that you've declared before the first %union. To generate + the post-prologue, Bison concatenates all prologue blocks that you've + declared after the first %union. + + Previous releases of Bison inserted the pre-prologue into both the header + file and the code file in all cases except for LALR(1) parsers in C. In the + latter case, Bison inserted it only into the code file. For parsers in C++, + the point of insertion was before any token definitions (which associate + token numbers with names). For parsers in C, the point of insertion was + after the token definitions. + + Now, Bison never inserts the pre-prologue into the header file. In the code + file, it always inserts it before the token definitions. + +** Bison now provides a more flexible alternative to the traditional Yacc + prologue blocks: %before-header, %start-header, %end-header, and + %after-header. + + For example, the following declaration order in the grammar file reflects the + order in which Bison will output these code blocks. However, you are free to + declare these code blocks in your grammar file in whatever order is most + convenient for you: + + %before-header { + /* Bison treats this block like a pre-prologue block: it inserts it into + * the code file before the contents of the header file. It does *not* + * insert it into the header file. This is a good place to put + * #include's that you want at the top of your code file. A common + * example is `#include "system.h"'. */ + } + %start-header { + /* Bison inserts this block into both the header file and the code file. + * In both files, the point of insertion is before any Bison-generated + * token, semantic type, location type, and class definitions. This is a + * good place to define %union dependencies, for example. */ + } + %union { + /* Unlike the traditional Yacc prologue blocks, the output order for the + * new %*-header blocks is not affected by their declaration position + * relative to any %union in the grammar file. */ + } + %end-header { + /* Bison inserts this block into both the header file and the code file. + * In both files, the point of insertion is after the Bison-generated + * definitions.

Previously, this permission + was granted only for Bison-generated LALR(1) parsers in C. + +** %name-prefix changes the namespace name in C++ outputs. + +** The C++ parsers export their token_type. + +** Bison now allows multiple %union declarations, and concatenates + their contents together. + +** New warning: unused values + Right-hand side symbols whose values are not used are reported, + if the symbols have destructors. For instance: + + exp: exp "?" exp ":" exp { $1 ? $1 : $3; } + | exp "+" exp + ; + + will trigger a warning about $$ and $5 in the first rule, and $3 in + the second ($1 is copied to $$ by the default rule). This example + most likely contains three errors, and could be rewritten as: + + exp: exp "?" exp ":" exp + { $$ = $1 ? $3 : $5; free ($1 ? $5 : $3); free ($1); } + | exp "+" exp + { $$ = $1 ? $1 : $3; if ($1) free ($3); } + ; + + However, if the original actions were really intended, memory leaks + and all, the warnings can be suppressed by letting Bison believe the + values are used, e.g.: + + exp: exp "?" exp ":" exp { $1 ? $1 : $3; (void) ($$, $5); } + | exp "+" exp { $$ = $1; (void) $3; } + ; + + If there are mid-rule actions, the warning is issued if no action + uses it. The following triggers no warning: $1 and $3 are used. + + exp: exp { push ($1); } '+' exp { push ($3); sum (); }; + + The warning is intended to help catching lost values and memory leaks. + If a value is ignored, its associated memory typically is not reclaimed. + +** %destructor vs. YYABORT, YYACCEPT, and YYERROR. + Destructors are now called when user code invokes YYABORT, YYACCEPT, + and YYERROR, for all objects on the stack, other than objects + corresponding to the right-hand side of the current rule. + +** %expect, %expect-rr + Incorrect numbers of expected conflicts are now actual errors, + instead of warnings. + +** GLR, YACC parsers. + The %parse-params are available in the destructors (and the + experimental printers) as per the documentation. + +** Bison now warns if it finds a stray `$' or `@' in an action. + +** %require "VERSION" + This specifies that the grammar file depends on features implemented + in Bison version VERSION or higher. + +** lalr1.cc: The token and value types are now class members. + The tokens were defined as free form enums and cpp macros. YYSTYPE + was defined as a free form union. They are now class members: + tokens are enumerations of the `yy::parser::token' struct, and the + semantic values have the `yy::parser::semantic_type' type. + + If you do not want or can update to this scheme, the directive + `%define "global_tokens_and_yystype" "1"' triggers the global + definition of tokens and YYSTYPE. This change is suitable both + for previous releases of Bison, and this one. + + If you wish to update, then make sure older version of Bison will + fail using `%require "2.2"'. + +** DJGPP support added. + +* Changes in version 2.1, 2005-09-16: + +** The C++ lalr1.cc skeleton supports %lex-param. + +** Bison-generated parsers now support the translation of diagnostics like + "syntax error" into languages other than English. The default + language is still English. For details, please see the new + Internationalization section of the Bison manual. Software + distributors should also see the new PACKAGING file. Thanks to + Bruno Haible for this new feature. + +** Wording in the Bison-generated parsers has been changed slightly to + simplify translation. In particular, the message "memory exhausted" + has replaced "parser stack overflow", as the old message was not + always accurate for modern Bison-generated parsers. + +** Destructors are now called when the parser aborts, for all symbols left + behind on the stack. Also, the start symbol is now destroyed after a + successful parse. In both cases, the behavior was formerly inconsistent. + +** When generating verbose diagnostics, Bison-generated parsers no longer + quote the literal strings associated with tokens. For example, for + a syntax error associated with '%token NUM "number"' they might + print 'syntax error, unexpected number' instead of 'syntax error, + unexpected "number"'. + +* Changes in version 2.0, 2004-12-25: + +** Possibly-incompatible changes + + - Bison-generated parsers no longer default to using the alloca function + (when available) to extend the parser stack, due to widespread + problems in unchecked stack-overflow detection. You can "#define + YYSTACK_USE_ALLOCA 1" to require the use of alloca, but please read + the manual to determine safe values for YYMAXDEPTH in that case. + + - Error token location. + During error recovery, the location of the syntax error is updated + to cover the whole sequence covered by the error token: it includes + the shifted symbols thrown away during the first part of the error + recovery, and the lookahead rejected during the second part. + + - Semicolon changes: + . Stray semicolons are no longer allowed at the start of a grammar. + . Semicolons are now required after in-grammar declarations. + + - Unescaped newlines are no longer allowed in character constants or + string literals. They were never portable, and GCC 3.4.0 has + dropped support for them. Better diagnostics are now generated if + forget a closing quote. + + - NUL bytes are no longer allowed in Bison string literals, unfortunately. + +** New features + + - GLR grammars now support locations. + + - New directive: %initial-action. + This directive allows the user to run arbitrary code (including + initializing @$) from yyparse before parsing starts. + + - A new directive "%expect-rr N" specifies the expected number of + reduce/reduce conflicts in GLR parsers. + + - %token numbers can now be hexadecimal integers, e.g., `%token FOO 0x12d'. + This is a GNU extension. + + - The option `--report=lookahead' was changed to `--report=look-ahead'. + [However, this was changed back after 2.3.] + + - Experimental %destructor support has been added to lalr1.cc. + + - New configure option --disable-yacc, to disable installation of the + yacc command and -ly library introduced in 1.875 for POSIX conformance. + +** Bug fixes + + - For now, %expect-count violations are now just warnings, not errors. + This is for compatibility with Bison 1.75 and earlier (when there are + reduce/reduce conflicts) and with Bison 1.30 and earlier (when there + are too many or too few shift/reduce conflicts). However, in future + versions of Bison we plan to improve the %expect machinery so that + these violations will become errors again. + + - Within Bison itself, numbers (e.g., goto numbers) are no longer + arbitrarily limited to 16-bit counts. + + - Semicolons are now allowed before "|" in grammar rules, as POSIX requires. + +* Changes in version 1.875, 2003-01-01: + +** The documentation license has been upgraded to version 1.2 + of the GNU Free Documentation License. + +** syntax error processing + + - In Yacc-style parsers YYLLOC_DEFAULT is now used to compute error + locations too. This fixes bugs in error-location computation. + + - %destructor + It is now possible to reclaim the memory associated to symbols + discarded during error recovery. This feature is still experimental. + + - %error-verbose + This new directive is preferred over YYERROR_VERBOSE. + + - #defining yyerror to steal internal variables is discouraged. + It is not guaranteed to work forever. + +** POSIX conformance + + - Semicolons are once again optional at the end of grammar rules. + This reverts to the behavior of Bison 1.33 and earlier, and improves + compatibility with Yacc. + + - `parse error' -> `syntax error' + Bison now uniformly uses the term `syntax error'; formerly, the code + and manual sometimes used the term `parse error' instead. POSIX + requires `syntax error' in diagnostics, and it was thought better to + be consistent. + + - The documentation now emphasizes that yylex and yyerror must be + declared before use. C99 requires this. + + - Bison now parses C99 lexical constructs like UCNs and + backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires. + + - File names are properly escaped in C output. E.g., foo\bar.y is + output as "foo\\bar.y". + + - Yacc command and library now available + The Bison distribution now installs a `yacc' command, as POSIX requires. + Also, Bison now installs a small library liby.a containing + implementations of Yacc-compatible yyerror and main functions. + This library is normally not useful, but POSIX requires it. + + - Type clashes now generate warnings, not errors. + + - If the user does not define YYSTYPE as a macro, Bison now declares it + using typedef instead of defining it as a macro. + For consistency, YYLTYPE is also declared instead of defined. + +** Other compatibility issues + + - %union directives can now have a tag before the `{', e.g., the + directive `%union foo {...}' now generates the C code + `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility. + The default union tag is `YYSTYPE', for compatibility with Solaris 9 Yacc. + For consistency, YYLTYPE's struct tag is now `YYLTYPE' not `yyltype'. + This is for compatibility with both Yacc and Bison 1.35. + + - `;' is output before the terminating `}' of an action, for + compatibility with Bison 1.35. + + - Bison now uses a Yacc-style format for conflict reports, e.g., + `conflicts: 2 shift/reduce, 1 reduce/reduce'. + + - `yystype' and `yyltype' are now obsolescent macros instead of being + typedefs or tags; they are no longer documented and are planned to be + withdrawn in a future release. + +** GLR parser notes + + - GLR and inline + Users of Bison have to decide how they handle the portability of the + C keyword `inline'. + + - `parsing stack overflow...' -> `parser stack overflow' + GLR parsers now report `parser stack overflow' as per the Bison manual. + +** Bison now warns if it detects conflicting outputs to the same file, + e.g., it generates a warning for `bison -d -o foo.h foo.y' since + that command outputs both code and header to foo.h. + +** #line in output files + - --no-line works properly. + +** Bison can no longer be built by a K&R C compiler; it requires C89 or + later to be built. This change originally took place a few versions + ago, but nobody noticed until we recently asked someone to try + building Bison with a K&R C compiler. + +* Changes in version 1.75, 2002-10-14: + +** Bison should now work on 64-bit hosts. + +** Indonesian translation thanks to Tedi Heriyanto. + +** GLR parsers + Fix spurious parse errors. + +** Pure parsers + Some people redefine yyerror to steal yyparse' private variables. + Reenable this trick until an official feature replaces it. + +** Type Clashes + In agreement with POSIX and with other Yaccs, leaving a default + action is valid when $$ is untyped, and $1 typed: + + untyped: ... typed; + + but the converse remains an error: + + typed: ... untyped; + +** Values of mid-rule actions + The following code: + + foo: { ... } { $$ = $1; } ... + + was incorrectly rejected: $1 is defined in the second mid-rule + action, and is equal to the $$ of the first mid-rule action. + +* Changes in version 1.50, 2002-10-04: + +** GLR parsing + The declaration + %glr-parser + causes Bison to produce a Generalized LR (GLR) parser, capable of handling + almost any context-free grammar, ambiguous or not. The new declarations + %dprec and %merge on grammar rules allow parse-time resolution of + ambiguities. Contributed by Paul Hilfinger. + + Unfortunately Bison 1.50 does not work properly on 64-bit hosts + like the Alpha, so please stick to 32-bit hosts for now. + +** Output Directory + When not in Yacc compatibility mode, when the output file was not + specified, running `bison foo/bar.y' created `foo/bar.c'. It + now creates `bar.c'. + +** Undefined token + The undefined token was systematically mapped to 2 which prevented + the use of 2 by the user. This is no longer the case. + +** Unknown token numbers + If yylex returned an out of range value, yyparse could die. This is + no longer the case. + +** Error token + According to POSIX, the error token must be 256. + Bison extends this requirement by making it a preference: *if* the + user specified that one of her tokens is numbered 256, then error + will be mapped onto another number. + +** Verbose error messages + They no longer report `..., expecting error or...' for states where + error recovery is possible. + +** End token + Defaults to `$end' instead of `$'. + +** Error recovery now conforms to documentation and to POSIX + When a Bison-generated parser encounters a syntax error, it now pops + the stack until it finds a state that allows shifting the error + token. Formerly, it popped the stack until it found a state that + allowed some non-error action other than a default reduction on the + error token. The new behavior has long been the documented behavior, + and has long been required by POSIX. For more details, please see + Paul Eggert, "Reductions during Bison error handling" (2002-05-20) + . + +** Traces + Popped tokens and nonterminals are now reported. + +** Larger grammars + Larger grammars are now supported (larger token numbers, larger grammar + size (= sum of the LHS and RHS lengths), larger LALR tables). + Formerly, many of these numbers ran afoul of 16-bit limits; + now these limits are 32 bits on most hosts. + +** Explicit initial rule + Bison used to play hacks with the initial rule, which the user does + not write. It is now explicit, and visible in the reports and + graphs as rule 0. + +** Useless rules + Before, Bison reported the useless rules, but, although not used, + included them in the parsers. They are now actually removed. + +** Useless rules, useless nonterminals + They are now reported, as a warning, with their locations. + +** Rules never reduced + Rules that can never be reduced because of conflicts are now + reported. + +** Incorrect `Token not used' + On a grammar such as + + %token useless useful + %% + exp: '0' %prec useful; + + where a token was used to set the precedence of the last rule, + bison reported both `useful' and `useless' as useless tokens. + +** Revert the C++ namespace changes introduced in 1.31 + as they caused too many portability hassles. + +** Default locations + By an accident of design, the default computation of @$ was + performed after another default computation was performed: @$ = @1. + The latter is now removed: YYLLOC_DEFAULT is fully responsible of + the computation of @$. + +** Token end-of-file + The token end of file may be specified by the user, in which case, + the user symbol is used in the reports, the graphs, and the verbose + error messages instead of `$end', which remains being the default. + For instance + %token MYEOF 0 + or + %token MYEOF 0 "end of file" + +** Semantic parser + This old option, which has been broken for ages, is removed. + +** New translations + Brazilian Portuguese, thanks to Alexandre Folle de Menezes. + Croatian, thanks to Denis Lackovic. + +** Incorrect token definitions + When given `%token 'a' "A"', Bison used to output `#define 'a' 65'. + +** Token definitions as enums + Tokens are output both as the traditional #define's, and, provided + the compiler supports ANSI C or is a C++ compiler, as enums. + This lets debuggers display names instead of integers. + +** Reports + In addition to --verbose, bison supports --report=THINGS, which + produces additional information: + - itemset + complete the core item sets with their closure + - lookahead [changed to `look-ahead' in 1.875e through 2.3, but changed back] + explicitly associate lookahead tokens to items + - solved + describe shift/reduce conflicts solving. + Bison used to systematically output this information on top of + the report. Solved conflicts are now attached to their states. + +** Type clashes + Previous versions don't complain when there is a type clash on + the default action if the rule has a mid-rule action, such as in: + + %type bar + %% + bar: '0' {} '0'; + + This is fixed. + +** GNU M4 is now required when using Bison. + +* Changes in version 1.35, 2002-03-25: + +** C Skeleton + Some projects use Bison's C parser with C++ compilers, and define + YYSTYPE as a class. The recent adjustment of C parsers for data + alignment and 64 bit architectures made this impossible. + + Because for the time being no real solution for C++ parser + generation exists, kludges were implemented in the parser to + maintain this use. In the future, when Bison has C++ parsers, this + kludge will be disabled. + + This kludge also addresses some C++ problems when the stack was + extended. + +* Changes in version 1.34, 2002-03-12: + +** File name clashes are detected + $ bison foo.y -d -o foo.x + fatal error: header and parser would both be named `foo.x' + +** A missing `;' at the end of a rule triggers a warning + In accordance with POSIX, and in agreement with other + Yacc implementations, Bison will mandate this semicolon in the near + future. This eases the implementation of a Bison parser of Bison + grammars by making this grammar LALR(1) instead of LR(2). To + facilitate the transition, this release introduces a warning. + +** Revert the C++ namespace changes introduced in 1.31, as they caused too + many portability hassles. + +** DJGPP support added. + +** Fix test suite portability problems. + +* Changes in version 1.33, 2002-02-07: + +** Fix C++ issues + Groff could not be compiled for the definition of size_t was lacking + under some conditions. + +** Catch invalid @n + As is done with $n. + +* Changes in version 1.32, 2002-01-23: + +** Fix Yacc output file names + +** Portability fixes + +** Italian, Dutch translations + +* Changes in version 1.31, 2002-01-14: + +** Many Bug Fixes + +** GNU Gettext and %expect + GNU Gettext asserts 10 s/r conflicts, but there are 7. Now that + Bison dies on incorrect %expectations, we fear there will be + too many bug reports for Gettext, so _for the time being_, %expect + does not trigger an error when the input file is named `plural.y'. + +** Use of alloca in parsers + If YYSTACK_USE_ALLOCA is defined to 0, then the parsers will use + malloc exclusively. Since 1.29, but was not NEWS'ed. + + alloca is used only when compiled with GCC, to avoid portability + problems as on AIX. + +** yyparse now returns 2 if memory is exhausted; formerly it dumped core. + +** When the generated parser lacks debugging code, YYDEBUG is now 0 + (as POSIX requires) instead of being undefined. + +** User Actions + Bison has always permitted actions such as { $$ = $1 }: it adds the + ending semicolon. Now if in Yacc compatibility mode, the semicolon + is no longer output: one has to write { $$ = $1; }. + +** Better C++ compliance + The output parsers try to respect C++ namespaces. + [This turned out to be a failed experiment, and it was reverted later.] + +** Reduced Grammars + Fixed bugs when reporting useless nonterminals. + +** 64 bit hosts + The parsers work properly on 64 bit hosts. + +** Error messages + Some calls to strerror resulted in scrambled or missing error messages. + +** %expect + When the number of shift/reduce conflicts is correct, don't issue + any warning. + +** The verbose report includes the rule line numbers. + +** Rule line numbers are fixed in traces. + +** Swedish translation + +** Parse errors + Verbose parse error messages from the parsers are better looking. + Before: parse error: unexpected `'/'', expecting `"number"' or `'-'' or `'('' + Now: parse error: unexpected '/', expecting "number" or '-' or '(' + +** Fixed parser memory leaks. + When the generated parser was using malloc to extend its stacks, the + previous allocations were not freed. + +** Fixed verbose output file. + Some newlines were missing. + Some conflicts in state descriptions were missing. + +** Fixed conflict report. + Option -v was needed to get the result. + +** %expect + Was not used. + Mismatches are errors, not warnings. + +** Fixed incorrect processing of some invalid input. + +** Fixed CPP guards: 9foo.h uses BISON_9FOO_H instead of 9FOO_H. + +** Fixed some typos in the documentation. + +** %token MY_EOF 0 is supported. + Before, MY_EOF was silently renumbered as 257. + +** doc/refcard.tex is updated. + +** %output, %file-prefix, %name-prefix. + New. + +** --output + New, aliasing `--output-file'. + +* Changes in version 1.30, 2001-10-26: + +** `--defines' and `--graph' have now an optional argument which is the + output file name. `-d' and `-g' do not change; they do not take any + argument. + +** `%source_extension' and `%header_extension' are removed, failed + experiment. + +** Portability fixes. + +* Changes in version 1.29, 2001-09-07: + +** The output file does not define const, as this caused problems when used + with common autoconfiguration schemes. If you still use ancient compilers + that lack const, compile with the equivalent of the C compiler option + `-Dconst='. autoconf's AC_C_CONST macro provides one way to do this. + +** Added `-g' and `--graph'. + +** The Bison manual is now distributed under the terms of the GNU FDL. + +** The input and the output files has automatically a similar extension. + +** Russian translation added. + +** NLS support updated; should hopefully be less troublesome. + +** Added the old Bison reference card. + +** Added `--locations' and `%locations'. + +** Added `-S' and `--skeleton'. + +** `%raw', `-r', `--raw' is disabled. + +** Special characters are escaped when output.

The yylex function can use this +table to recognize multiple-character string tokens, or for other +purposes. + +** The %no_lines declaration says not to generate any #line preprocessor +directives in the parser file. + +** The %raw declaration says to use internal Bison token numbers, not +Yacc-compatible token numbers, when token names are defined as macros. + +** The --no-parser option produces the parser tables without including +the parser engine; a project can now use its own parser engine. +The actions go into a separate file called NAME.act, in the form of +a switch statement body. + +* Changes in version 1.23: + +The user can define YYPARSE_PARAM as the name of an argument to be +passed into yyparse. The argument should have type void *. It should +actually point to an object.

We should +move to partial orders (sounds like series/parallel orders to me). + +** Correlation b/w precedence and associativity +Also, I fail to understand why we have to assign the same +associativity to operators with the same precedence. For instance, +why can't I decide that the precedence of * and / is the same, but the +latter is nonassoc? + +If there is really no profound motivation, we should find a new syntax +to allow specifying this. + +** RR conflicts +See if we can use precedence between rules to solve RR conflicts. See +what POSIX says. + + +* $undefined +From Hans: +- If the Bison generated parser experiences an undefined number in the +character range, that character is written out in diagnostic messages, an +addition to the $undefined value. + +Suggest: Change the name $undefined to undefined; looks better in outputs. + + +* Default Action +From Hans: +- For use with my C++ parser, I transported the "switch (yyn)" statement +that Bison writes to the bison.simple skeleton file. This way, I can remove +the current default rule $$ = $1 implementation, which causes a double +assignment to $$ which may not be OK under C++, replacing it with a +"default:" part within the switch statement. + +Note that the default rule $$ = $1, when typed, is perfectly OK under C, +but in the C++ implementation I made, this rule is different from +$$ = $1. I therefore think that one should implement +a Bison option where every typed default rule is explicitly written out +(same typed ruled can of course be grouped together). + +Note: Robert Anisko handles this. He knows how to do it. + + +* Warnings +It would be nice to have warning support. See how Autoconf handles +them, it is fairly well described there. It would be very nice to +implement this in such a way that other programs could use +lib/warnings.[ch]. + +Don't work on this without first announcing you do, as I already have +thought about it, and know many of the components that can be used to +implement it. + + +* Pre and post actions. +From: Florian Krohm +Subject: YYACT_EPILOGUE +To: bug-bison@gnu.org +X-Sent: 1 week, 4 days, 14 hours, 38 minutes, 11 seconds ago + +The other day I had the need for explicitly building the parse tree. I +used %locations for that and defined YYLLOC_DEFAULT to call a function +that returns the tree node for the production. Easy. But I also needed +to assign the S-attribute to the tree node. That cannot be done in +YYLLOC_DEFAULT, because it is invoked before the action is executed. +The way I solved this was to define a macro YYACT_EPILOGUE that would +be invoked after the action. For reasons of symmetry I also added +YYACT_PROLOGUE. Although I had no use for that I can envision how it +might come in handy for debugging purposes. +All is needed is to add + +#if YYLSP_NEEDED + YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen, yyloc, (yylsp - yylen)); +#else + YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen); +#endif + +at the proper place to bison.simple.

This means that an +# algorithm on n arguments that recurses with one less argument each +# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time. In +# M4 1.6, this was fixed so that $@ is only scanned once, then +# back-references are made to information stored about the scan. +# Thus, n iterations need only scan n arguments, for O(n) time. +# Additionally, in M4 1.4.x, recursive algorithms did not clean up +# memory very well, requiring O(n^2) memory rather than O(n) for n +# iterations. +# +# This file is designed to overcome the quadratic nature of $@ +# recursion by writing a variant of m4_foreach that uses m4_for rather +# than $@ recursion to operate on the list. This involves more macro +# expansions, but avoids the need to rescan a quadratic number of +# arguments, making these replacements very attractive for M4 1.4.x. +# On the other hand, in any version of M4, expanding additional macros +# costs additional time; therefore, in M4 1.6, where $@ recursion uses +# fewer macros, these replacements actually pessimize performance. +# Additionally, the use of $10 to mean the tenth argument violates +# POSIX; although all versions of m4 1.4.x support this meaning, a +# future m4 version may switch to take it as the first argument +# concatenated with a literal 0, so the implementations in this file +# are not future-proof. Thus, this file is conditionally included as +# part of m4_init(), only when it is detected that M4 probably has +# quadratic behavior (ie. it lacks the macro __m4_version__). +# +# Please keep this file in sync with m4sugar.m4. + +# m4_foreach(VARIABLE, LIST, EXPRESSION) +# -------------------------------------- +# Expand EXPRESSION assigning each value of the LIST to VARIABLE. +# LIST should have the form `item_1, item_2, ..., item_n', i.e. the +# whole list must *quoted*. Quote members too if you don't want them +# to be expanded. +# +# This version minimizes the number of times that $@ is evaluated by +# using m4_for to generate a boilerplate into VARIABLE then passing $@ +# to that temporary macro. Thus, the recursion is done in m4_for +# without reparsing any user input, and is not quadratic. For an idea +# of how this works, note that m4_foreach(i,[1,2],[i]) defines i to be +# m4_define([$1],[$3])$2[]m4_define([$1],[$4])$2[]m4_popdef([i]) +# then calls i([i],[i],[1],[2]). +m4_define([m4_foreach], +[m4_if([$2], [], [], [_$0([$1], [$3], $2)])]) + +m4_define([_m4_foreach], +[m4_define([$1], m4_pushdef([$1])_m4_for([$1], [3], [$#], [1], + [$0_([1], [2], _m4_defn([$1]))])[m4_popdef([$1])])m4_indir([$1], $@)]) + +m4_define([_m4_foreach_], +[[m4_define([$$1], [$$3])$$2[]]]) + +# m4_case(SWITCH, VAL1, IF-VAL1, VAL2, IF-VAL2, ..., DEFAULT) +# ----------------------------------------------------------- +# Find the first VAL that SWITCH matches, and expand the corresponding +# IF-VAL.

This is what Autoconf 2.0 (I think) to 2.13 (I'm sure) +# implement. +# +# +# The second idea: first required first out +# ----------------------------------------- +# +# The natural implementation of the idea above is buggy and produces +# very surprising results in some situations. Let's consider the +# following example to explain the bug: +# +# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])]) +# | m4_defun([TEST2a], []) +# | m4_defun([TEST2b], [REQUIRE([TEST3])]) +# | m4_defun([TEST3], [REQUIRE([TEST2a])]) +# | +# | AC_INIT +# | TEST1 +# +# The dependencies between the macros are: +# +# 3 --- 2b +# / \ is m4_require'd by +# / \ left -------------------- right +# 2a ------------ 1 +# +# If you strictly apply the rules given in the previous section you get: +# +# GROW - 2: TEST3 +# GROW - 1: TEST2a; TEST2b +# GROW: TEST1 +# BODY: +# +# (TEST2a, although required by TEST3 is not expanded in GROW - 3 +# because is has already been expanded before in GROW - 1, so it has +# been AC_PROVIDE'd, so it is not expanded again) so when you undivert +# the stack of diversions, you get: +# +# GROW - 2: +# GROW - 1: +# GROW: +# BODY: TEST3; TEST2a; TEST2b; TEST1 +# +# i.e., TEST2a is expanded after TEST3 although the latter required the +# former. +# +# Starting from 2.50, we use an implementation provided by Axel Thimm. +# The idea is simple: the order in which macros are emitted must be the +# same as the one in which macros are expanded. (The bug above can +# indeed be described as: a macro has been AC_PROVIDE'd before its +# dependent, but it is emitted after: the lack of correlation between +# emission and expansion order is guilty). +# +# How to do that? You keep the stack of diversions to elaborate the +# macros, but each time a macro is fully expanded, emit it immediately. +# +# In the example above, when TEST2a is expanded, but it's epilogue is +# not run yet, you have: +# +# GROW - 2: +# GROW - 1: TEST2a +# GROW: Elaboration of TEST1 +# BODY: +# +# The epilogue of TEST2a emits it immediately: +# +# GROW - 2: +# GROW - 1: +# GROW: Elaboration of TEST1 +# BODY: TEST2a +# +# TEST2b then requires TEST3, so right before the epilogue of TEST3, you +# have: +# +# GROW - 2: TEST3 +# GROW - 1: Elaboration of TEST2b +# GROW: Elaboration of TEST1 +# BODY: TEST2a +# +# The epilogue of TEST3 emits it: +# +# GROW - 2: +# GROW - 1: Elaboration of TEST2b +# GROW: Elaboration of TEST1 +# BODY: TEST2a; TEST3 +# +# TEST2b is now completely expanded, and emitted: +# +# GROW - 2: +# GROW - 1: +# GROW: Elaboration of TEST1 +# BODY: TEST2a; TEST3; TEST2b +# +# and finally, TEST1 is finished and emitted: +# +# GROW - 2: +# GROW - 1: +# GROW: +# BODY: TEST2a; TEST3; TEST2b: TEST1 +# +# The idea is simple, but the implementation is a bit evolved. If you +# are like me, you will want to see the actual functioning of this +# implementation to be convinced. The next section gives the full +# details. +# +# +# The Axel Thimm implementation at work +# ------------------------------------- +# +# We consider the macros above, and this configure.ac: +# +# AC_INIT +# TEST1 +# +# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and +# m4_require at hand to follow the steps. +# +# This implements tries not to assume that the current diversion is +# BODY, so as soon as a macro (m4_defun'd) is expanded, we first +# record the current diversion under the name _m4_divert_dump (denoted +# DUMP below for short). This introduces an important difference with +# the previous versions of Autoconf: you cannot use m4_require if you +# are not inside an m4_defun'd macro, and especially, you cannot +# m4_require directly from the top level. +# +# We have not tried to simulate the old behavior (better yet, we +# diagnose it), because it is too dangerous: a macro m4_require'd from +# the top level is expanded before the body of `configure', i.e., before +# any other test was run. I let you imagine the result of requiring +# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run.... +# +# After AC_INIT was run, the current diversion is BODY. +# * AC_INIT was run +# DUMP: undefined +# diversion stack: BODY |- +# +# * TEST1 is expanded +# The prologue of TEST1 sets _m4_divert_dump, which is the diversion +# where the current elaboration will be dumped, to the current +# diversion.

Keeping track of the expansion stack +# ======================================= +# +# When M4 expansion goes wrong it is often extremely hard to find the +# path amongst macros that drove to the failure. What is needed is +# the stack of macro `calls'. One could imagine that GNU M4 would +# maintain a stack of macro expansions, unfortunately it doesn't, so +# we do it by hand. This is of course extremely costly, but the help +# this stack provides is worth it. Nevertheless to limit the +# performance penalty this is implemented only for m4_defun'd macros, +# not for define'd macros. +# +# The scheme is simplistic: each time we enter an m4_defun'd macros, +# we prepend its name in m4_expansion_stack, and when we exit the +# macro, we remove it (thanks to pushdef/popdef). +# +# In addition, we want to detect circular m4_require dependencies. +# Each time we expand a macro FOO we define _m4_expanding(FOO); and +# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined. + + +# m4_expansion_stack_push(TEXT) +# ----------------------------- +m4_define([m4_expansion_stack_push], +[m4_pushdef([m4_expansion_stack], + [$1]m4_ifdef([m4_expansion_stack], [ +_m4_defn([m4_expansion_stack])]))]) + + +# m4_expansion_stack_pop +# ---------------------- +m4_define([m4_expansion_stack_pop], +[m4_popdef([m4_expansion_stack])]) + + +# m4_expansion_stack_dump +# ----------------------- +# Dump the expansion stack. +m4_define([m4_expansion_stack_dump], +[m4_ifdef([m4_expansion_stack], + [m4_errprintn(_m4_defn([m4_expansion_stack]))])dnl +m4_errprintn(m4_location[: the top level])]) + + +# _m4_divert(GROW) +# ---------------- +# This diversion is used by the m4_defun/m4_require machinery.

How do we track all of these set members, +# without introducing duplicates? We could use m4_append_uniq, with +# the set NAME residing in the contents of the macro NAME. +# Unfortunately, m4_append_uniq is quadratic for set creation, because +# it costs O(n) to search the string for each of O(n) insertions; not +# to mention that with m4 1.4.x, even using m4_append is slow, costing +# O(n) rather than O(1) per insertion. Other set operations, not used +# by Autoconf but still possible by manipulation of the definition +# tracked in macro NAME, include O(n) deletion of one element and O(n) +# computation of set size. Because the set is exposed to the user via +# the definition of a single macro, we cannot cache any data about the +# set without risking the cache being invalidated by the user +# redefining NAME. +# +# Can we do better? Yes, because m4 gives us an O(1) search function +# for free: ifdef. Additionally, even m4 1.4.x gives us an O(1) +# insert operation for free: pushdef. But to use these, we must +# represent the set via a group of macros; to keep the set consistent, +# we must hide the set so that the user can only manipulate it through +# accessor macros. The contents of the set are maintained through two +# access points; _m4_set([name]) is a pushdef stack of values in the +# set, useful for O(n) traversal of the set contents; while the +# existence of _m4_set([name],value) with no particular value is +# useful for O(1) querying of set membership. And since the user +# cannot externally manipulate the set, we are free to add additional +# caching macros for other performance improvements. Deletion can be +# O(1) per element rather than O(n), by reworking the definition of +# _m4_set([name],value) to be 0 or 1 based on current membership, and +# adding _m4_set_cleanup(name) to defer the O(n) cleanup of +# _m4_set([name]) until we have another reason to do an O(n) +# traversal. The existence of _m4_set_cleanup(name) can then be used +# elsewhere to determine if we must dereference _m4_set([name],value), +# or assume that definition implies set membership.

See the +GNU General Public License for more details. + +You should have received a copy of the GNU General Public License +along with this program. If not, see . + + +1.: DJGPP specific changes. + ======================= + + The DJGPP port of Bison offers LFN and SFN support depending on which + OS it is running. If LFN support is available or not is determinated at + run time. If LFN support is available (DOS session under Win9X, Win2K, + WinXP, etc.) the standard posix file name extensions will be used. + These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc. If only SFN + support is available (plain DOS), then the standard MSDOS short file + names will be used. These are: y_tab.c, y_tab.h, y.out, etc. + It should be noticed that this bison version needs the m4 program as + back end to generate the parser file (y.tab.c etc.) from the skeleton + files. This implies that m4 must always be installed to get bison + working. m4 will use a couple of m4 scripts that will be installed in + /dev/env/DJDIR/share/bison and shall not be removed. + It should also be noticed that the skeleton files bison.simple and + bison.hairy are no longer supported. This applies also to the environ- + ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no* + longer honored at all. + The kind of skeleton file bison.hairy is no longer supported at all. + The skeleton file bison.simple is now called yacc.c and is an m4 script. + The other two skeleton files supported by this bison version are glr.c + and lalr1.cc. The first one is a generalized LR C parser based on + Bison's LALR(1) tables and the second one is a experimental C++ parser + class. + As has been told before, bison uses m4 to generate the parser file. + This is done by forking and using pipes for the IPC. MSDOS does not + support this functionality so this has been reproduced in the usual + way by redirecting stdin and stdout of bison and m4 to temporary files + and processing these files in sequence. + It should be noticed that due to the great amount of file names that do + not cleanly map to 8.3 file names, you will need an OS with LFN support + to configure and compile the sources. On Win98 this implies that the + generation of numeric tails for 8.3 file name aliases must be enabled + or the compilation will fail. + + + Please **read** the docs. + + +2.: Installing the binary package. + ============================== + +2.1.: Copy the binary distribution into the top DJGPP installation directory, + just unzip it preserving the directory structure running *ONE* of the + following commands: + unzip32 bsn@PACKAGE_VERSION@b.zip or + djtarx bsn@PACKAGE_VERSION@b.zip or + pkunzip -d bsn@PACKAGE_VERSION@b.zip + + + +3.: Building the binaries from sources. + =================================== + +3.1.: Create a temporary directory and copy the source package into the + directory. If you download the source distribution from one of the + DJGPP sites, just unzip it preserving the directory structure + running *ONE* of the following commands: + unzip32 bsn@PACKAGE_VERSION@s.zip or + djtarx bsn@PACKAGE_VERSION@s.zip or + pkunzip -d bsn@PACKAGE_VERSION@s.zip + and proceed to the paragraph 3.3, below. + +3.2.: Source distributions downloaded from one of the GNU FTP sites need + some more work to unpack, if LFN support is not available. If LFN is + available then you can extract the source files from the archive with + any unzip program and proceed to the paragraph 3.3, below. Any file + name issue will be handled by the the DJGPP configuration files. + To unpack the source distribution on SFN systems, first, you MUST use + the `djunpack' batch file to unzip the package. That is because some + file names in the official distributions need to be changed to avoid + problems on the various platforms supported by DJGPP. + `djunpack' invokes the `djtar' program (that is part of the basic DJGPP + development kit) to rename these files on the fly given a file with + name mappings; the distribution includes a file `djgpp/fnchange.lst' + with the necessary mappings. So you need first to retrieve that batch + file, and then invoke it to unpack the distribution. Here's how: + + djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat + djunpack bison-@VERSION@.tar.gz + + (The name of the distribution archive and the leading directory of the + path to `djunpack.bat' in the distribution will be different for + versions of Bison other than @VERSION@.) + + If the argument to `djunpack.bat' include leading directories, it MUST + be given with the DOS-style backslashes; Unix-style forward slashes + will NOT work. + + If the distribution comes as a .tar.bz2 archive, and your version of + `djtar' doesn't support bzip2 decompression, you need to unpack it as + follows: + + bnzip2 bison-@VERSION@.tar.bz2 + djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat + djunpack bison-@VERSION@.tar + +3.3.: To build the binaries you will need the following binary packages: + djdev203.zip (or a later but NOT a prior version) + bsh204b.zip (or a later but NOT a prior version) + gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip, + perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, + sedNNNb.zip and m4NNN.zip + + If you want to run the check you will need also: + difNNNb.zip + + NNN represents the latest version number of the binary packages. All + this packages can be found in the /v2gnu directory of any + ftp.delorie.com mirror. + You will need bsh204b.zip or later and *NOT* a prior version or + the build will fail. The same applies to djdev203.zip. Please note + that Bison requires m4-144b.zip or later to work properly. + +3.4.: If for some reason you want to reconfigure the package cd into the top + srcdir (bison-@TREE_VERSION@) and run the following commands: + del djgpp\config.cache + make clean + djgpp\config + + Please note that you *MUST* delete the config.cache file in the djgpp + subdir or you will not really reconfigure the sources because the + configuration informations will be read from the cache file instead + of being newly computed. + To build the programs in a directory other than where the sources are, + you must add the parameter that specifies the source directory, + e.g: + x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@ + + Lets assume you want to build the binaries in a directory placed on a + different drive (z:\build in this case) from where the sources are, + then you will run the following commands: + z: + md \build + cd \build + x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@ + + The order of the options and the srcdir option does not matter. You + *MUST* use forward slashes to specify the source directory. + + The batch file will set same environment variables, make MSDOS specific + modifications to the Makefile.in's and supply all other needed options + to the configure script. + +3.5.: To compile the package run from the top srcdir the command: + make + +3.6.: Now you can run the tests if you like. From the top srcdir run the + command: + make check + + No test should fail but the tests #131 (Doxygen Public Documentation) + and #132 (Doxygen Private Documentation) will be skipped. Please note + that the testsuite only works with LFN available. On plain DOS, most + of the tests will fail due to invalid DOS names. + +3.7.: To install the binaries, header, library, catalogs, and info docs + run the following command from the top srcdir: + make install + + This will install the products into your DJGPP installation tree given + by the default prefix "/dev/env/DJDIR". If you prefer to install them + into some other directory you will have to set prefix to the appropiate + value: + make install prefix=z:/some/other/place + + + + Send GNU bison specific bug reports to . + Send suggestions and bug reports concerning the DJGPP port to + comp.os.msdos.djgpp or . + + +Enjoy. + + Guerrero, Juan Manuel diff --git a/djgpp/config.bat b/djgpp/config.bat new file mode 100644 index 0000000..61a02d6 --- /dev/null +++ b/djgpp/config.bat @@ -0,0 +1,547 @@ +@echo off +Rem Configure Bison for DJGPP. + +Rem WARNING WARNING WARNING: This file needs to have DOS CRLF end-of-line +Rem format, or else stock DOS/Windows shells will refuse to run it. + +Rem Copyright (C) 2005, 2006, 2007, 2008 Free Software Foundation, Inc. + +Rem This program is free software: you can redistribute it and/or modify +Rem it under the terms of the GNU General Public License as published by +Rem the Free Software Foundation, either version 3 of the License, or +Rem (at your option) any later version. +Rem +Rem This program is distributed in the hope that it will be useful, +Rem but WITHOUT ANY WARRANTY; without even the implied warranty of +Rem MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Long option names are indicated with +.B \-\- +instead of +.BR \- . +Abbreviations for option names are allowed as long as they +are unique.

Once you are proficient with Bison, you can use it to develop +a wide range of language parsers, from those used in simple desk +calculators to complex programming languages. + + Bison is upward compatible with Yacc: all properly-written Yacc +grammars ought to work with Bison with no change. Anyone familiar with +Yacc should be able to use Bison with little trouble. You need to be +fluent in C or C++ programming in order to use Bison or to understand +this manual. + + We begin with tutorial chapters that explain the basic concepts of +using Bison and show three explained examples, each building on the +last. If you don't know Bison or Yacc, start by reading these +chapters. Reference chapters follow which describe specific aspects of +Bison in detail. + + Bison was written primarily by Robert Corbett; Richard Stallman made +it Yacc-compatible. Wilfred Hansen of Carnegie Mellon University added +multi-character string literals and other features. + + This edition corresponds to version 2.4.1 of Bison. + + +File: bison.info, Node: Conditions, Next: Copying, Prev: Introduction, Up: Top + +Conditions for Using Bison +************************** + +The distribution terms for Bison-generated parsers permit using the +parsers in nonfree programs. Before Bison version 2.2, these extra +permissions applied only when Bison was generating LALR(1) parsers in +C. And before Bison version 1.24, Bison-generated parsers could be +used only in programs that were free software. + + The other GNU programming tools, such as the GNU C compiler, have +never had such a requirement. They could always be used for nonfree +software. The reason Bison was different was not due to a special +policy decision; it resulted from applying the usual General Public +License to all of the Bison source code. + + The output of the Bison utility--the Bison parser file--contains a +verbatim copy of a sizable piece of Bison, which is the code for the +parser's implementation. (The actions from your grammar are inserted +into this implementation at one point, but most of the rest of the +implementation is not changed.) When we applied the GPL terms to the +skeleton code for the parser's implementation, the effect was to +restrict the use of Bison output to free software. + + We didn't change the terms because of sympathy for people who want to +make software proprietary. *Software should be free.* But we +concluded that limiting Bison's use to free software was doing little to +encourage people to make other software free. So we decided to make the +practical conditions for using Bison match the practical conditions for +using the other GNU tools. + + This exception applies when Bison is generating code for a parser. +You can tell whether the exception applies to a Bison output file by +inspecting the file for text beginning with "As a special +exception...". The text spells out the exact terms of the exception. + + +File: bison.info, Node: Copying, Next: Concepts, Prev: Conditions, Up: Top + +GNU GENERAL PUBLIC LICENSE +************************** + + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. `http://fsf.org/' + + Everyone is permitted to copy and distribute verbatim copies of this + license document, but changing it is not allowed. + +Preamble +======== + +The GNU General Public License is a free, copyleft license for software +and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains +free software for all its users. We, the Free Software Foundation, use +the GNU General Public License for most of our software; it applies +also to any other work released this way by its authors. You can apply +it to your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you +have certain responsibilities if you distribute copies of the software, +or if you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the +manufacturer can do so. This is fundamentally incompatible with the +aim of protecting users' freedom to change the software. The +systematic pattern of such abuse occurs in the area of products for +individuals to use, which is precisely where it is most unacceptable. +Therefore, we have designed this version of the GPL to prohibit the +practice for those products. If such problems arise substantially in +other domains, we stand ready to extend this provision to those domains +in future versions of the GPL, as needed to protect the freedom of +users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + +TERMS AND CONDITIONS +==================== + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public + License. + + "Copyright" also means copyright-like laws that apply to other + kinds of works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this + License. Each licensee is addressed as "you". "Licensees" and + "recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the + work in a fashion requiring copyright permission, other than the + making of an exact copy. The resulting work is called a "modified + version" of the earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work + based on the Program. + + To "propagate" a work means to do anything with it that, without + permission, would make you directly or secondarily liable for + infringement under applicable copyright law, except executing it + on a computer or modifying a private copy. Propagation includes + copying, distribution (with or without modification), making + available to the public, and in some countries other activities as + well. + + To "convey" a work means any kind of propagation that enables other + parties to make or receive copies. Mere interaction with a user + through a computer network, with no transfer of a copy, is not + conveying. + + An interactive user interface displays "Appropriate Legal Notices" + to the extent that it includes a convenient and prominently visible + feature that (1) displays an appropriate copyright notice, and (2) + tells the user that there is no warranty for the work (except to + the extent that warranties are provided), that licensees may + convey the work under this License, and how to view a copy of this + License. If the interface presents a list of user commands or + options, such as a menu, a prominent item in the list meets this + criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work + for making modifications to it. "Object code" means any + non-source form of a work. + + A "Standard Interface" means an interface that either is an + official standard defined by a recognized standards body, or, in + the case of interfaces specified for a particular programming + language, one that is widely used among developers working in that + language. + + The "System Libraries" of an executable work include anything, + other than the work as a whole, that (a) is included in the normal + form of packaging a Major Component, but which is not part of that + Major Component, and (b) serves only to enable use of the work + with that Major Component, or to implement a Standard Interface + for which an implementation is available to the public in source + code form. A "Major Component", in this context, means a major + essential component (kernel, window system, and so on) of the + specific operating system (if any) on which the executable work + runs, or a compiler used to produce the work, or an object code + interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all + the source code needed to generate, install, and (for an executable + work) run the object code and to modify the work, including + scripts to control those activities. However, it does not include + the work's System Libraries, or general-purpose tools or generally + available free programs which are used unmodified in performing + those activities but which are not part of the work. For example, + Corresponding Source includes interface definition files + associated with source files for the work, and the source code for + shared libraries and dynamically linked subprograms that the work + is specifically designed to require, such as by intimate data + communication or control flow between those subprograms and other + parts of the work. + + The Corresponding Source need not include anything that users can + regenerate automatically from other parts of the Corresponding + Source. + + The Corresponding Source for a work in source code form is that + same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of + copyright on the Program, and are irrevocable provided the stated + conditions are met. This License explicitly affirms your unlimited + permission to run the unmodified Program. The output from running + a covered work is covered by this License only if the output, + given its content, constitutes a covered work. This License + acknowledges your rights of fair use or other equivalent, as + provided by copyright law. + + You may make, run and propagate covered works that you do not + convey, without conditions so long as your license otherwise + remains in force. You may convey covered works to others for the + sole purpose of having them make modifications exclusively for + you, or provide you with facilities for running those works, + provided that you comply with the terms of this License in + conveying all material for which you do not control copyright. + Those thus making or running the covered works for you must do so + exclusively on your behalf, under your direction and control, on + terms that prohibit them from making any copies of your + copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under + the conditions stated below. Sublicensing is not allowed; section + 10 makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological + measure under any applicable law fulfilling obligations under + article 11 of the WIPO copyright treaty adopted on 20 December + 1996, or similar laws prohibiting or restricting circumvention of + such measures. + + When you convey a covered work, you waive any legal power to forbid + circumvention of technological measures to the extent such + circumvention is effected by exercising rights under this License + with respect to the covered work, and you disclaim any intention + to limit operation or modification of the work as a means of + enforcing, against the work's users, your or third parties' legal + rights to forbid circumvention of technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you + receive it, in any medium, provided that you conspicuously and + appropriately publish on each copy an appropriate copyright notice; + keep intact all notices stating that this License and any + non-permissive terms added in accord with section 7 apply to the + code; keep intact all notices of the absence of any warranty; and + give all recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, + and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to + produce it from the Program, in the form of source code under the + terms of section 4, provided that you also meet all of these + conditions: + + a. The work must carry prominent notices stating that you + modified it, and giving a relevant date. + + b. The work must carry prominent notices stating that it is + released under this License and any conditions added under + section 7. This requirement modifies the requirement in + section 4 to "keep intact all notices". + + c. You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable + section 7 additional terms, to the whole of the work, and all + its parts, regardless of how they are packaged. This License + gives no permission to license the work in any other way, but + it does not invalidate such permission if you have separately + received it. + + d. If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has + interactive interfaces that do not display Appropriate Legal + Notices, your work need not make them do so. + + A compilation of a covered work with other separate and independent + works, which are not by their nature extensions of the covered + work, and which are not combined with it such as to form a larger + program, in or on a volume of a storage or distribution medium, is + called an "aggregate" if the compilation and its resulting + copyright are not used to limit the access or legal rights of the + compilation's users beyond what the individual works permit. + Inclusion of a covered work in an aggregate does not cause this + License to apply to the other parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms + of sections 4 and 5, provided that you also convey the + machine-readable Corresponding Source under the terms of this + License, in one of these ways: + + a. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for + as long as you offer spare parts or customer support for that + product model, to give anyone who possesses the object code + either (1) a copy of the Corresponding Source for all the + software in the product that is covered by this License, on a + durable physical medium customarily used for software + interchange, for a price no more than your reasonable cost of + physically performing this conveying of source, or (2) access + to copy the Corresponding Source from a network server at no + charge. + + c. Convey individual copies of the object code with a copy of + the written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, + and only if you received the object code with such an offer, + in accord with subsection 6b. + + d. Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access + to the Corresponding Source in the same way through the same + place at no further charge. You need not require recipients + to copy the Corresponding Source along with the object code. + If the place to copy the object code is a network server, the + Corresponding Source may be on a different server (operated + by you or a third party) that supports equivalent copying + facilities, provided you maintain clear directions next to + the object code saying where to find the Corresponding Source. + Regardless of what server hosts the Corresponding Source, you + remain obligated to ensure that it is available for as long + as needed to satisfy these requirements. + + e. Convey the object code using peer-to-peer transmission, + provided you inform other peers where the object code and + Corresponding Source of the work are being offered to the + general public at no charge under subsection 6d. + + + A separable portion of the object code, whose source code is + excluded from the Corresponding Source as a System Library, need + not be included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means + any tangible personal property which is normally used for personal, + family, or household purposes, or (2) anything designed or sold for + incorporation into a dwelling. In determining whether a product + is a consumer product, doubtful cases shall be resolved in favor of + coverage. For a particular product received by a particular user, + "normally used" refers to a typical or common use of that class of + product, regardless of the status of the particular user or of the + way in which the particular user actually uses, or expects or is + expected to use, the product. A product is a consumer product + regardless of whether the product has substantial commercial, + industrial or non-consumer uses, unless such uses represent the + only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, + procedures, authorization keys, or other information required to + install and execute modified versions of a covered work in that + User Product from a modified version of its Corresponding Source. + The information must suffice to ensure that the continued + functioning of the modified object code is in no case prevented or + interfered with solely because modification has been made. + + If you convey an object code work under this section in, or with, + or specifically for use in, a User Product, and the conveying + occurs as part of a transaction in which the right of possession + and use of the User Product is transferred to the recipient in + perpetuity or for a fixed term (regardless of how the transaction + is characterized), the Corresponding Source conveyed under this + section must be accompanied by the Installation Information. But + this requirement does not apply if neither you nor any third party + retains the ability to install modified object code on the User + Product (for example, the work has been installed in ROM). + + The requirement to provide Installation Information does not + include a requirement to continue to provide support service, + warranty, or updates for a work that has been modified or + installed by the recipient, or for the User Product in which it + has been modified or installed. Access to a network may be denied + when the modification itself materially and adversely affects the + operation of the network or violates the rules and protocols for + communication across the network. + + Corresponding Source conveyed, and Installation Information + provided, in accord with this section must be in a format that is + publicly documented (and with an implementation available to the + public in source code form), and must require no special password + or key for unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of + this License by making exceptions from one or more of its + conditions. Additional permissions that are applicable to the + entire Program shall be treated as though they were included in + this License, to the extent that they are valid under applicable + law. If additional permissions apply only to part of the Program, + that part may be used separately under those permissions, but the + entire Program remains governed by this License without regard to + the additional permissions. + + When you convey a copy of a covered work, you may at your option + remove any additional permissions from that copy, or from any part + of it. (Additional permissions may be written to require their own + removal in certain cases when you modify the work.) You may place + additional permissions on material, added by you to a covered work, + for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material + you add to a covered work, you may (if authorized by the copyright + holders of that material) supplement the terms of this License + with terms: + + a. Disclaiming warranty or limiting liability differently from + the terms of sections 15 and 16 of this License; or + + b. Requiring preservation of specified reasonable legal notices + or author attributions in that material or in the Appropriate + Legal Notices displayed by works containing it; or + + c. Prohibiting misrepresentation of the origin of that material, + or requiring that modified versions of such material be + marked in reasonable ways as different from the original + version; or + + d. Limiting the use for publicity purposes of names of licensors + or authors of the material; or + + e. Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f. Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified + versions of it) with contractual assumptions of liability to + the recipient, for any liability that these contractual + assumptions directly impose on those licensors and authors. + + All other non-permissive additional terms are considered "further + restrictions" within the meaning of section 10. If the Program as + you received it, or any part of it, contains a notice stating that + it is governed by this License along with a term that is a further + restriction, you may remove that term. If a license document + contains a further restriction but permits relicensing or + conveying under this License, you may add to a covered work + material governed by the terms of that license document, provided + that the further restriction does not survive such relicensing or + conveying. + + If you add terms to a covered work in accord with this section, you + must place, in the relevant source files, a statement of the + additional terms that apply to those files, or a notice indicating + where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in + the form of a separately written license, or stated as exceptions; + the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly + provided under this License. Any attempt otherwise to propagate or + modify it is void, and will automatically terminate your rights + under this License (including any patent licenses granted under + the third paragraph of section 11). + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly + and finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from + you under this License. If your rights have been terminated and + not permanently reinstated, you do not qualify to receive new + licenses for the same material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or + run a copy of the Program. Ancillary propagation of a covered work + occurring solely as a consequence of using peer-to-peer + transmission to receive a copy likewise does not require + acceptance. However, nothing other than this License grants you + permission to propagate or modify any covered work. These actions + infringe copyright if you do not accept this License. Therefore, + by modifying or propagating a covered work, you indicate your + acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically + receives a license from the original licensors, to run, modify and + propagate that work, subject to this License. You are not + responsible for enforcing compliance by third parties with this + License. + + An "entity transaction" is a transaction transferring control of an + organization, or substantially all assets of one, or subdividing an + organization, or merging organizations. If propagation of a + covered work results from an entity transaction, each party to that + transaction who receives a copy of the work also receives whatever + licenses to the work the party's predecessor in interest had or + could give under the previous paragraph, plus a right to + possession of the Corresponding Source of the work from the + predecessor in interest, if the predecessor has it or can get it + with reasonable efforts. + + You may not impose any further restrictions on the exercise of the + rights granted or affirmed under this License.

Patents. + + A "contributor" is a copyright holder who authorizes use under this + License of the Program or a work on which the Program is based. + The work thus licensed is called the contributor's "contributor + version". + + A contributor's "essential patent claims" are all patent claims + owned or controlled by the contributor, whether already acquired or + hereafter acquired, that would be infringed by some manner, + permitted by this License, of making, using, or selling its + contributor version, but do not include claims that would be + infringed only as a consequence of further modification of the + contributor version. For purposes of this definition, "control" + includes the right to grant patent sublicenses in a manner + consistent with the requirements of this License. + + Each contributor grants you a non-exclusive, worldwide, + royalty-free patent license under the contributor's essential + patent claims, to make, use, sell, offer for sale, import and + otherwise run, modify and propagate the contents of its + contributor version. + + In the following three paragraphs, a "patent license" is any + express agreement or commitment, however denominated, not to + enforce a patent (such as an express permission to practice a + patent or covenant not to sue for patent infringement). To + "grant" such a patent license to a party means to make such an + agreement or commitment not to enforce a patent against the party. + + If you convey a covered work, knowingly relying on a patent + license, and the Corresponding Source of the work is not available + for anyone to copy, free of charge and under the terms of this + License, through a publicly available network server or other + readily accessible means, then you must either (1) cause the + Corresponding Source to be so available, or (2) arrange to deprive + yourself of the benefit of the patent license for this particular + work, or (3) arrange, in a manner consistent with the requirements + of this License, to extend the patent license to downstream + recipients.

If you do not already know how to +use Bison or Yacc, we suggest you start by reading this chapter +carefully. + +* Menu: + +* Language and Grammar:: Languages and context-free grammars, + as mathematical ideas. +* Grammar in Bison:: How we represent grammars for Bison's sake. +* Semantic Values:: Each token or syntactic grouping can have + a semantic value (the value of an integer, + the name of an identifier, etc.). +* Semantic Actions:: Each rule can have an action containing C code. +* GLR Parsers:: Writing parsers for general context-free languages. +* Locations Overview:: Tracking Locations. +* Bison Parser:: What are Bison's input and output, + how is the output used? +* Stages:: Stages in writing and running Bison grammars. +* Grammar Layout:: Overall structure of a Bison grammar file. + + +File: bison.info, Node: Language and Grammar, Next: Grammar in Bison, Up: Concepts + +1.1 Languages and Context-Free Grammars +======================================= + +In order for Bison to parse a language, it must be described by a +"context-free grammar". This means that you specify one or more +"syntactic groupings" and give rules for constructing them from their +parts. For example, in the C language, one kind of grouping is called +an `expression'. One rule for making an expression might be, "An +expression can be made of a minus sign and another expression". +Another would be, "An expression can be an integer". As you can see, +rules are often recursive, but there must be at least one rule which +leads out of the recursion. + + The most common formal system for presenting such rules for humans +to read is "Backus-Naur Form" or "BNF", which was developed in order to +specify the language Algol 60. Any grammar expressed in BNF is a +context-free grammar. The input to Bison is essentially +machine-readable BNF. + + There are various important subclasses of context-free grammar. +Although it can handle almost all context-free grammars, Bison is +optimized for what are called LALR(1) grammars. In brief, in these +grammars, it must be possible to tell how to parse any portion of an +input string with just a single token of lookahead. Strictly speaking, +that is a description of an LR(1) grammar, and LALR(1) involves +additional restrictions that are hard to explain simply; but it is rare +in actual practice to find an LR(1) grammar that fails to be LALR(1). +*Note Mysterious Reduce/Reduce Conflicts: Mystery Conflicts, for more +information on this. + + Parsers for LALR(1) grammars are "deterministic", meaning roughly +that the next grammar rule to apply at any point in the input is +uniquely determined by the preceding input and a fixed, finite portion +(called a "lookahead") of the remaining input. A context-free grammar +can be "ambiguous", meaning that there are multiple ways to apply the +grammar rules to get the same inputs. Even unambiguous grammars can be +"nondeterministic", meaning that no fixed lookahead always suffices to +determine the next grammar rule to apply. With the proper +declarations, Bison is also able to parse these more general +context-free grammars, using a technique known as GLR parsing (for +Generalized LR). Bison's GLR parsers are able to handle any +context-free grammar for which the number of possible parses of any +given string is finite. + + In the formal grammatical rules for a language, each kind of +syntactic unit or grouping is named by a "symbol". Those which are +built by grouping smaller constructs according to grammatical rules are +called "nonterminal symbols"; those which can't be subdivided are called +"terminal symbols" or "token types". We call a piece of input +corresponding to a single terminal symbol a "token", and a piece +corresponding to a single nonterminal symbol a "grouping". + + We can use the C language as an example of what symbols, terminal and +nonterminal, mean. The tokens of C are identifiers, constants (numeric +and string), and the various keywords, arithmetic operators and +punctuation marks. So the terminal symbols of a grammar for C include +`identifier', `number', `string', plus one symbol for each keyword, +operator or punctuation mark: `if', `return', `const', `static', `int', +`char', `plus-sign', `open-brace', `close-brace', `comma' and many more. +(These tokens can be subdivided into characters, but that is a matter of +lexicography, not grammar.) + + Here is a simple C function subdivided into tokens: + + int /* keyword `int' */ + square (int x) /* identifier, open-paren, keyword `int', + identifier, close-paren */ + { /* open-brace */ + return x * x; /* keyword `return', identifier, asterisk, + identifier, semicolon */ + } /* close-brace */ + + The syntactic groupings of C include the expression, the statement, +the declaration, and the function definition. These are represented in +the grammar of C by nonterminal symbols `expression', `statement', +`declaration' and `function definition'. The full grammar uses dozens +of additional language constructs, each with its own nonterminal +symbol, in order to express the meanings of these four. The example +above is a function definition; it contains one declaration, and one +statement. In the statement, each `x' is an expression and so is `x * +x'. + + Each nonterminal symbol must have grammatical rules showing how it +is made out of simpler constructs. For example, one kind of C +statement is the `return' statement; this would be described with a +grammar rule which reads informally as follows: + + A `statement' can be made of a `return' keyword, an `expression' + and a `semicolon'. + +There would be many other rules for `statement', one for each kind of +statement in C. + + One nonterminal symbol must be distinguished as the special one which +defines a complete utterance in the language. It is called the "start +symbol". In a compiler, this means a complete input program. In the C +language, the nonterminal symbol `sequence of definitions and +declarations' plays this role. + + For example, `1 + 2' is a valid C expression--a valid part of a C +program--but it is not valid as an _entire_ C program. In the +context-free grammar of C, this follows from the fact that `expression' +is not the start symbol. + + The Bison parser reads a sequence of tokens as its input, and groups +the tokens using the grammar rules. If the input is valid, the end +result is that the entire token sequence reduces to a single grouping +whose symbol is the grammar's start symbol. If we use a grammar for C, +the entire input must be a `sequence of definitions and declarations'. +If not, the parser reports a syntax error. + + +File: bison.info, Node: Grammar in Bison, Next: Semantic Values, Prev: Language and Grammar, Up: Concepts + +1.2 From Formal Rules to Bison Input +==================================== + +A formal grammar is a mathematical construct. To define the language +for Bison, you must write a file expressing the grammar in Bison syntax: +a "Bison grammar" file. *Note Bison Grammar Files: Grammar File. + + A nonterminal symbol in the formal grammar is represented in Bison +input as an identifier, like an identifier in C. By convention, it +should be in lower case, such as `expr', `stmt' or `declaration'. + + The Bison representation for a terminal symbol is also called a +"token type". Token types as well can be represented as C-like +identifiers. By convention, these identifiers should be upper case to +distinguish them from nonterminals: for example, `INTEGER', +`IDENTIFIER', `IF' or `RETURN'. A terminal symbol that stands for a +particular keyword in the language should be named after that keyword +converted to upper case. The terminal symbol `error' is reserved for +error recovery. *Note Symbols::. + + A terminal symbol can also be represented as a character literal, +just like a C character constant. You should do this whenever a token +is just a single character (parenthesis, plus-sign, etc.): use that +same character in a literal as the terminal symbol for that token. + + A third way to represent a terminal symbol is with a C string +constant containing several characters. *Note Symbols::, for more +information. + + The grammar rules also have an expression in Bison syntax. For +example, here is the Bison rule for a C `return' statement. The +semicolon in quotes is a literal character token, representing part of +the C syntax for the statement; the naked semicolon, and the colon, are +Bison punctuation used in every rule. + + stmt: RETURN expr ';' + ; + +*Note Syntax of Grammar Rules: Rules. + + +File: bison.info, Node: Semantic Values, Next: Semantic Actions, Prev: Grammar in Bison, Up: Concepts + +1.3 Semantic Values +=================== + +A formal grammar selects tokens only by their classifications: for +example, if a rule mentions the terminal symbol `integer constant', it +means that _any_ integer constant is grammatically valid in that +position. The precise value of the constant is irrelevant to how to +parse the input: if `x+4' is grammatical then `x+1' or `x+3989' is +equally grammatical. + + But the precise value is very important for what the input means +once it is parsed. A compiler is useless if it fails to distinguish +between 4, 1 and 3989 as constants in the program! Therefore, each +token in a Bison grammar has both a token type and a "semantic value". +*Note Defining Language Semantics: Semantics, for details. + + The token type is a terminal symbol defined in the grammar, such as +`INTEGER', `IDENTIFIER' or `',''. It tells everything you need to know +to decide where the token may validly appear and how to group it with +other tokens. The grammar rules know nothing about tokens except their +types. + + The semantic value has all the rest of the information about the +meaning of the token, such as the value of an integer, or the name of an +identifier. (A token such as `','' which is just punctuation doesn't +need to have any semantic value.) + + For example, an input token might be classified as token type +`INTEGER' and have the semantic value 4. Another input token might +have the same token type `INTEGER' but value 3989. When a grammar rule +says that `INTEGER' is allowed, either of these tokens is acceptable +because each is an `INTEGER'. When the parser accepts the token, it +keeps track of the token's semantic value. + + Each grouping can also have a semantic value as well as its +nonterminal symbol. For example, in a calculator, an expression +typically has a semantic value that is a number. In a compiler for a +programming language, an expression typically has a semantic value that +is a tree structure describing the meaning of the expression. + + +File: bison.info, Node: Semantic Actions, Next: GLR Parsers, Prev: Semantic Values, Up: Concepts + +1.4 Semantic Actions +==================== + +In order to be useful, a program must do more than parse input; it must +also produce some output based on the input. In a Bison grammar, a +grammar rule can have an "action" made up of C statements. Each time +the parser recognizes a match for that rule, the action is executed. +*Note Actions::. + + Most of the time, the purpose of an action is to compute the +semantic value of the whole construct from the semantic values of its +parts. For example, suppose we have a rule which says an expression +can be the sum of two expressions. When the parser recognizes such a +sum, each of the subexpressions has a semantic value which describes +how it was built up. The action for this rule should create a similar +sort of value for the newly recognized larger expression. + + For example, here is a rule that says an expression can be the sum of +two subexpressions: + + expr: expr '+' expr { $$ = $1 + $3; } + ; + +The action says how to produce the semantic value of the sum expression +from the values of the two subexpressions. + + +File: bison.info, Node: GLR Parsers, Next: Locations Overview, Prev: Semantic Actions, Up: Concepts + +1.5 Writing GLR Parsers +======================= + +In some grammars, Bison's standard LALR(1) parsing algorithm cannot +decide whether to apply a certain grammar rule at a given point. That +is, it may not be able to decide (on the basis of the input read so +far) which of two possible reductions (applications of a grammar rule) +applies, or whether to apply a reduction or read more of the input and +apply a reduction later in the input. These are known respectively as +"reduce/reduce" conflicts (*note Reduce/Reduce::), and "shift/reduce" +conflicts (*note Shift/Reduce::). + + To use a grammar that is not easily modified to be LALR(1), a more +general parsing algorithm is sometimes necessary. If you include +`%glr-parser' among the Bison declarations in your file (*note Grammar +Outline::), the result is a Generalized LR (GLR) parser. These parsers +handle Bison grammars that contain no unresolved conflicts (i.e., after +applying precedence declarations) identically to LALR(1) parsers. +However, when faced with unresolved shift/reduce and reduce/reduce +conflicts, GLR parsers use the simple expedient of doing both, +effectively cloning the parser to follow both possibilities. Each of +the resulting parsers can again split, so that at any given time, there +can be any number of possible parses being explored. The parsers +proceed in lockstep; that is, all of them consume (shift) a given input +symbol before any of them proceed to the next. Each of the cloned +parsers eventually meets one of two possible fates: either it runs into +a parsing error, in which case it simply vanishes, or it merges with +another parser, because the two of them have reduced the input to an +identical set of symbols. + + During the time that there are multiple parsers, semantic actions are +recorded, but not performed. When a parser disappears, its recorded +semantic actions disappear as well, and are never performed. When a +reduction makes two parsers identical, causing them to merge, Bison +records both sets of semantic actions. Whenever the last two parsers +merge, reverting to the single-parser case, Bison resolves all the +outstanding actions either by precedences given to the grammar rules +involved, or by performing both actions, and then calling a designated +user-defined function on the resulting values to produce an arbitrary +merged result. + +* Menu: + +* Simple GLR Parsers:: Using GLR parsers on unambiguous grammars. +* Merging GLR Parses:: Using GLR parsers to resolve ambiguities. +* GLR Semantic Actions:: Deferred semantic actions have special concerns. +* Compiler Requirements:: GLR parsers require a modern C compiler. + + +File: bison.info, Node: Simple GLR Parsers, Next: Merging GLR Parses, Up: GLR Parsers + +1.5.1 Using GLR on Unambiguous Grammars +--------------------------------------- + +In the simplest cases, you can use the GLR algorithm to parse grammars +that are unambiguous, but fail to be LALR(1). Such grammars typically +require more than one symbol of lookahead, or (in rare cases) fall into +the category of grammars in which the LALR(1) algorithm throws away too +much information (they are in LR(1), but not LALR(1), *note Mystery +Conflicts::). + + Consider a problem that arises in the declaration of enumerated and +subrange types in the programming language Pascal. Here are some +examples: + + type subrange = lo .. hi; + type enum = (a, b, c); + +The original language standard allows only numeric literals and +constant identifiers for the subrange bounds (`lo' and `hi'), but +Extended Pascal (ISO/IEC 10206) and many other Pascal implementations +allow arbitrary expressions there. This gives rise to the following +situation, containing a superfluous pair of parentheses: + + type subrange = (a) .. b; + +Compare this to the following declaration of an enumerated type with +only one value: + + type enum = (a); + +(These declarations are contrived, but they are syntactically valid, +and more-complicated cases can come up in practical programs.) + + These two declarations look identical until the `..' token. With +normal LALR(1) one-token lookahead it is not possible to decide between +the two forms when the identifier `a' is parsed. It is, however, +desirable for a parser to decide this, since in the latter case `a' +must become a new identifier to represent the enumeration value, while +in the former case `a' must be evaluated with its current meaning, +which may be a constant or even a function call. + + You could parse `(a)' as an "unspecified identifier in parentheses", +to be resolved later, but this typically requires substantial +contortions in both semantic actions and large parts of the grammar, +where the parentheses are nested in the recursive rules for expressions. + + You might think of using the lexer to distinguish between the two +forms by returning different tokens for currently defined and undefined +identifiers. But if these declarations occur in a local scope, and `a' +is defined in an outer scope, then both forms are possible--either +locally redefining `a', or using the value of `a' from the outer scope. +So this approach cannot work. + + A simple solution to this problem is to declare the parser to use +the GLR algorithm. When the GLR parser reaches the critical state, it +merely splits into two branches and pursues both syntax rules +simultaneously. Sooner or later, one of them runs into a parsing +error. If there is a `..' token before the next `;', the rule for +enumerated types fails since it cannot accept `..' anywhere; otherwise, +the subrange type rule fails since it requires a `..' token. So one of +the branches fails silently, and the other one continues normally, +performing all the intermediate actions that were postponed during the +split. + + If the input is syntactically incorrect, both branches fail and the +parser reports a syntax error as usual. + + The effect of all this is that the parser seems to "guess" the +correct branch to take, or in other words, it seems to use more +lookahead than the underlying LALR(1) algorithm actually allows for. +In this example, LALR(2) would suffice, but also some cases that are +not LALR(k) for any k can be handled this way. + + In general, a GLR parser can take quadratic or cubic worst-case time, +and the current Bison parser even takes exponential time and space for +some grammars. In practice, this rarely happens, and for many grammars +it is possible to prove that it cannot happen. The present example +contains only one conflict between two rules, and the type-declaration +context containing the conflict cannot be nested. So the number of +branches that can exist at any time is limited by the constant 2, and +the parsing time is still linear. + + Here is a Bison grammar corresponding to the example above. It +parses a vastly simplified form of Pascal type declarations. + + %token TYPE DOTDOT ID + + %left '+' '-' + %left '*' '/' + + %% + + type_decl : TYPE ID '=' type ';' + ; + + type : '(' id_list ')' + | expr DOTDOT expr + ; + + id_list : ID + | id_list ',' ID + ; + + expr : '(' expr ')' + | expr '+' expr + | expr '-' expr + | expr '*' expr + | expr '/' expr + | ID + ; + + When used as a normal LALR(1) grammar, Bison correctly complains +about one reduce/reduce conflict. In the conflicting situation the +parser chooses one of the alternatives, arbitrarily the one declared +first. Therefore the following correct input is not recognized: + + type t = (a) .. b; + + The parser can be turned into a GLR parser, while also telling Bison +to be silent about the one known reduce/reduce conflict, by adding +these two declarations to the Bison input file (before the first `%%'): + + %glr-parser + %expect-rr 1 + +No change in the grammar itself is required. Now the parser recognizes +all valid declarations, according to the limited syntax above, +transparently. In fact, the user does not even notice when the parser +splits. + + So here we have a case where we can use the benefits of GLR, almost +without disadvantages. Even in simple cases like this, however, there +are at least two potential problems to beware. First, always analyze +the conflicts reported by Bison to make sure that GLR splitting is only +done where it is intended. A GLR parser splitting inadvertently may +cause problems less obvious than an LALR parser statically choosing the +wrong alternative in a conflict. Second, consider interactions with +the lexer (*note Semantic Tokens::) with great care. Since a split +parser consumes tokens without performing any actions during the split, +the lexer cannot obtain information via parser actions. Some cases of +lexer interactions can be eliminated by using GLR to shift the +complications from the lexer to the parser. You must check the +remaining cases for correctness. + + In our example, it would be safe for the lexer to return tokens +based on their current meanings in some symbol table, because no new +symbols are defined in the middle of a type declaration. Though it is +possible for a parser to define the enumeration constants as they are +parsed, before the type declaration is completed, it actually makes no +difference since they cannot be used within the same enumerated type +declaration. + + +File: bison.info, Node: Merging GLR Parses, Next: GLR Semantic Actions, Prev: Simple GLR Parsers, Up: GLR Parsers + +1.5.2 Using GLR to Resolve Ambiguities +-------------------------------------- + +Let's consider an example, vastly simplified from a C++ grammar. + + %{ + #include + #define YYSTYPE char const * + int yylex (void); + void yyerror (char const *); + %} + + %token TYPENAME ID + + %right '=' + %left '+' + + %glr-parser + + %% + + prog : + | prog stmt { printf ("\n"); } + ; + + stmt : expr ';' %dprec 1 + | decl %dprec 2 + ; + + expr : ID { printf ("%s ", $$); } + | TYPENAME '(' expr ')' + { printf ("%s ", $1); } + | expr '+' expr { printf ("+ "); } + | expr '=' expr { printf ("= "); } + ; + + decl : TYPENAME declarator ';' + { printf ("%s ", $1); } + | TYPENAME declarator '=' expr ';' + { printf ("%s ", $1); } + ; + + declarator : ID { printf ("\"%s\" ", $1); } + | '(' declarator ')' + ; + +This models a problematic part of the C++ grammar--the ambiguity between +certain declarations and statements. For example, + + T (x) = y+z; + +parses as either an `expr' or a `stmt' (assuming that `T' is recognized +as a `TYPENAME' and `x' as an `ID'). Bison detects this as a +reduce/reduce conflict between the rules `expr : ID' and `declarator : +ID', which it cannot resolve at the time it encounters `x' in the +example above. Since this is a GLR parser, it therefore splits the +problem into two parses, one for each choice of resolving the +reduce/reduce conflict. Unlike the example from the previous section +(*note Simple GLR Parsers::), however, neither of these parses "dies," +because the grammar as it stands is ambiguous. One of the parsers +eventually reduces `stmt : expr ';'' and the other reduces `stmt : +decl', after which both parsers are in an identical state: they've seen +`prog stmt' and have the same unprocessed input remaining. We say that +these parses have "merged." + + At this point, the GLR parser requires a specification in the +grammar of how to choose between the competing parses. In the example +above, the two `%dprec' declarations specify that Bison is to give +precedence to the parse that interprets the example as a `decl', which +implies that `x' is a declarator. The parser therefore prints + + "x" y z + T + + The `%dprec' declarations only come into play when more than one +parse survives. Consider a different input string for this parser: + + T (x) + y; + +This is another example of using GLR to parse an unambiguous construct, +as shown in the previous section (*note Simple GLR Parsers::). Here, +there is no ambiguity (this cannot be parsed as a declaration). +However, at the time the Bison parser encounters `x', it does not have +enough information to resolve the reduce/reduce conflict (again, +between `x' as an `expr' or a `declarator'). In this case, no +precedence declaration is used. Again, the parser splits into two, one +assuming that `x' is an `expr', and the other assuming `x' is a +`declarator'. The second of these parsers then vanishes when it sees +`+', and the parser prints + + x T y + + + Suppose that instead of resolving the ambiguity, you wanted to see +all the possibilities. For this purpose, you must merge the semantic +actions of the two possible parsers, rather than choosing one over the +other. To do so, you could change the declaration of `stmt' as follows: + + stmt : expr ';' %merge + | decl %merge + ; + +and define the `stmtMerge' function as: + + static YYSTYPE + stmtMerge (YYSTYPE x0, YYSTYPE x1) + { + printf (" "); + return ""; + } + +with an accompanying forward declaration in the C declarations at the +beginning of the file: + + %{ + #define YYSTYPE char const * + static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1); + %} + +With these declarations, the resulting parser parses the first example +as both an `expr' and a `decl', and prints + + "x" y z + T x T y z + = + + Bison requires that all of the productions that participate in any +particular merge have identical `%merge' clauses. Otherwise, the +ambiguity would be unresolvable, and the parser will report an error +during any parse that results in the offending merge. + + +File: bison.info, Node: GLR Semantic Actions, Next: Compiler Requirements, Prev: Merging GLR Parses, Up: GLR Parsers + +1.5.3 GLR Semantic Actions +-------------------------- + +By definition, a deferred semantic action is not performed at the same +time as the associated reduction. This raises caveats for several +Bison features you might use in a semantic action in a GLR parser. + + In any semantic action, you can examine `yychar' to determine the +type of the lookahead token present at the time of the associated +reduction. After checking that `yychar' is not set to `YYEMPTY' or +`YYEOF', you can then examine `yylval' and `yylloc' to determine the +lookahead token's semantic value and location, if any. In a +nondeferred semantic action, you can also modify any of these variables +to influence syntax analysis. *Note Lookahead Tokens: Lookahead. + + In a deferred semantic action, it's too late to influence syntax +analysis. In this case, `yychar', `yylval', and `yylloc' are set to +shallow copies of the values they had at the time of the associated +reduction. For this reason alone, modifying them is dangerous. +Moreover, the result of modifying them is undefined and subject to +change with future versions of Bison. For example, if a semantic +action might be deferred, you should never write it to invoke +`yyclearin' (*note Action Features::) or to attempt to free memory +referenced by `yylval'. + + Another Bison feature requiring special consideration is `YYERROR' +(*note Action Features::), which you can invoke in a semantic action to +initiate error recovery. During deterministic GLR operation, the +effect of `YYERROR' is the same as its effect in an LALR(1) parser. In +a deferred semantic action, its effect is undefined. + + Also, see *note Default Action for Locations: Location Default +Action, which describes a special usage of `YYLLOC_DEFAULT' in GLR +parsers. + + +File: bison.info, Node: Compiler Requirements, Prev: GLR Semantic Actions, Up: GLR Parsers + +1.5.4 Considerations when Compiling GLR Parsers +----------------------------------------------- + +The GLR parsers require a compiler for ISO C89 or later. In addition, +they use the `inline' keyword, which is not C89, but is C99 and is a +common extension in pre-C99 compilers. It is up to the user of these +parsers to handle portability issues. For instance, if using Autoconf +and the Autoconf macro `AC_C_INLINE', a mere + + %{ + #include + %} + +will suffice. Otherwise, we suggest + + %{ + #if __STDC_VERSION__ < 199901 && ! defined __GNUC__ && ! defined inline + #define inline + #endif + %} + + +File: bison.info, Node: Locations Overview, Next: Bison Parser, Prev: GLR Parsers, Up: Concepts + +1.6 Locations +============= + +Many applications, like interpreters or compilers, have to produce +verbose and useful error messages. To achieve this, one must be able +to keep track of the "textual location", or "location", of each +syntactic construct. Bison provides a mechanism for handling these +locations. + + Each token has a semantic value. In a similar fashion, each token +has an associated location, but the type of locations is the same for +all tokens and groupings. Moreover, the output parser is equipped with +a default data structure for storing locations (*note Locations::, for +more details). + + Like semantic values, locations can be reached in actions using a +dedicated set of constructs. In the example above, the location of the +whole grouping is `@$', while the locations of the subexpressions are +`@1' and `@3'. + + When a rule is matched, a default action is used to compute the +semantic value of its left hand side (*note Actions::). In the same +way, another default action is used for locations. However, the action +for locations is general enough for most cases, meaning there is +usually no need to describe for each rule how `@$' should be formed. +When building a new location for a given grouping, the default behavior +of the output parser is to take the beginning of the first symbol, and +the end of the last symbol. + + +File: bison.info, Node: Bison Parser, Next: Stages, Prev: Locations Overview, Up: Concepts + +1.7 Bison Output: the Parser File +================================= + +When you run Bison, you give it a Bison grammar file as input. The +output is a C source file that parses the language described by the +grammar. This file is called a "Bison parser". Keep in mind that the +Bison utility and the Bison parser are two distinct programs: the Bison +utility is a program whose output is the Bison parser that becomes part +of your program. + + The job of the Bison parser is to group tokens into groupings +according to the grammar rules--for example, to build identifiers and +operators into expressions. As it does this, it runs the actions for +the grammar rules it uses. + + The tokens come from a function called the "lexical analyzer" that +you must supply in some fashion (such as by writing it in C). The Bison +parser calls the lexical analyzer each time it wants a new token. It +doesn't know what is "inside" the tokens (though their semantic values +may reflect this). Typically the lexical analyzer makes the tokens by +parsing characters of text, but Bison does not depend on this. *Note +The Lexical Analyzer Function `yylex': Lexical. + + The Bison parser file is C code which defines a function named +`yyparse' which implements that grammar. This function does not make a +complete C program: you must supply some additional functions. One is +the lexical analyzer. Another is an error-reporting function which the +parser calls to report an error. In addition, a complete C program must +start with a function called `main'; you have to provide this, and +arrange for it to call `yyparse' or the parser will never run. *Note +Parser C-Language Interface: Interface. + + Aside from the token type names and the symbols in the actions you +write, all symbols defined in the Bison parser file itself begin with +`yy' or `YY'. This includes interface functions such as the lexical +analyzer function `yylex', the error reporting function `yyerror' and +the parser function `yyparse' itself. This also includes numerous +identifiers used for internal purposes. Therefore, you should avoid +using C identifiers starting with `yy' or `YY' in the Bison grammar +file except for the ones defined in this manual. Also, you should +avoid using the C identifiers `malloc' and `free' for anything other +than their usual meanings. + + In some cases the Bison parser file includes system headers, and in +those cases your code should respect the identifiers reserved by those +headers. On some non-GNU hosts, `', `', +`', and `' are included as needed to declare memory +allocators and related types. `' is included if message +translation is in use (*note Internationalization::). Other system +headers may be included if you define `YYDEBUG' to a nonzero value +(*note Tracing Your Parser: Tracing.). + + +File: bison.info, Node: Stages, Next: Grammar Layout, Prev: Bison Parser, Up: Concepts + +1.8 Stages in Using Bison +========================= + +The actual language-design process using Bison, from grammar +specification to a working compiler or interpreter, has these parts: + + 1. Formally specify the grammar in a form recognized by Bison (*note + Bison Grammar Files: Grammar File.). For each grammatical rule in + the language, describe the action that is to be taken when an + instance of that rule is recognized. The action is described by a + sequence of C statements. + + 2. Write a lexical analyzer to process input and pass tokens to the + parser. The lexical analyzer may be written by hand in C (*note + The Lexical Analyzer Function `yylex': Lexical.). It could also + be produced using Lex, but the use of Lex is not discussed in this + manual. + + 3. Write a controlling function that calls the Bison-produced parser. + + 4. Write error-reporting routines. + + To turn this source code as written into a runnable program, you +must follow these steps: + + 1. Run Bison on the grammar to produce the parser. + + 2. Compile the code output by Bison, as well as any other source + files. + + 3. Link the object files to produce the finished product. + + +File: bison.info, Node: Grammar Layout, Prev: Stages, Up: Concepts + +1.9 The Overall Layout of a Bison Grammar +========================================= + +The input file for the Bison utility is a "Bison grammar file". The +general form of a Bison grammar file is as follows: + + %{ + PROLOGUE + %} + + BISON DECLARATIONS + + %% + GRAMMAR RULES + %% + EPILOGUE + +The `%%', `%{' and `%}' are punctuation that appears in every Bison +grammar file to separate the sections. + + The prologue may define types and variables used in the actions. +You can also use preprocessor commands to define macros used there, and +use `#include' to include header files that do any of these things. +You need to declare the lexical analyzer `yylex' and the error printer +`yyerror' here, along with any other global identifiers used by the +actions in the grammar rules. + + The Bison declarations declare the names of the terminal and +nonterminal symbols, and may also describe operator precedence and the +data types of semantic values of various symbols. + + The grammar rules define how to construct each nonterminal symbol +from its parts. + + The epilogue can contain any code you want to use. Often the +definitions of functions declared in the prologue go here. In a simple +program, all the rest of the program can go here. + + +File: bison.info, Node: Examples, Next: Grammar File, Prev: Concepts, Up: Top + +2 Examples +********** + +Now we show and explain three sample programs written using Bison: a +reverse polish notation calculator, an algebraic (infix) notation +calculator, and a multi-function calculator. All three have been tested +under BSD Unix 4.3; each produces a usable, though limited, interactive +desk-top calculator. + + These examples are simple, but Bison grammars for real programming +languages are written the same way.

This +example provides a good starting point, since operator precedence is +not an issue. The second example will illustrate how operator +precedence is handled. + + The source code for this calculator is named `rpcalc.y'.

The Bison parser will use +whatever type `YYSTYPE' is defined as; if you don't define it, `int' is +the default. Because we specify `double', each token and each +expression has an associated value, which is a floating point number. + + The `#include' directive is used to declare the exponentiation +function `pow'. + + The forward declarations for `yylex' and `yyerror' are needed +because the C language requires that functions be declared before they +are used. These functions will be defined in the epilogue, but the +parser calls them so they must be declared in the prologue. + + The second section, Bison declarations, provides information to Bison +about the token types (*note The Bison Declarations Section: Bison +Declarations.). Each terminal symbol that is not a single-character +literal must be declared here. (Single-character literals normally +don't need to be declared.) In this example, all the arithmetic +operators are designated by single-character literals, so the only +terminal symbol that needs to be declared is `NUM', the token type for +numeric constants. + + +File: bison.info, Node: Rpcalc Rules, Next: Rpcalc Lexer, Prev: Rpcalc Declarations, Up: RPN Calc + +2.1.2 Grammar Rules for `rpcalc' +-------------------------------- + +Here are the grammar rules for the reverse polish notation calculator. + + input: /* empty */ + | input line + ; + + line: '\n' + | exp '\n' { printf ("\t%.10g\n", $1); } + ; + + exp: NUM { $$ = $1; } + | exp exp '+' { $$ = $1 + $2; } + | exp exp '-' { $$ = $1 - $2; } + | exp exp '*' { $$ = $1 * $2; } + | exp exp '/' { $$ = $1 / $2; } + /* Exponentiation */ + | exp exp '^' { $$ = pow ($1, $2); } + /* Unary minus */ + | exp 'n' { $$ = -$1; } + ; + %% + + The groupings of the rpcalc "language" defined here are the +expression (given the name `exp'), the line of input (`line'), and the +complete input transcript (`input'). Each of these nonterminal symbols +has several alternate rules, joined by the vertical bar `|' which is +read as "or". The following sections explain what these rules mean. + + The semantics of the language is determined by the actions taken +when a grouping is recognized. The actions are the C code that appears +inside braces. *Note Actions::. + + You must specify these actions in C, but Bison provides the means for +passing semantic values between the rules. In each action, the +pseudo-variable `$$' stands for the semantic value for the grouping +that the rule is going to construct. Assigning a value to `$$' is the +main job of most actions. The semantic values of the components of the +rule are referred to as `$1', `$2', and so on. + +* Menu: + +* Rpcalc Input:: +* Rpcalc Line:: +* Rpcalc Expr:: + + +File: bison.info, Node: Rpcalc Input, Next: Rpcalc Line, Up: Rpcalc Rules + +2.1.2.1 Explanation of `input' +.............................. + +Consider the definition of `input': + + input: /* empty */ + | input line + ; + + This definition reads as follows: "A complete input is either an +empty string, or a complete input followed by an input line". Notice +that "complete input" is defined in terms of itself. This definition +is said to be "left recursive" since `input' appears always as the +leftmost symbol in the sequence. *Note Recursive Rules: Recursion. + + The first alternative is empty because there are no symbols between +the colon and the first `|'; this means that `input' can match an empty +string of input (no tokens). We write the rules this way because it is +legitimate to type `Ctrl-d' right after you start the calculator. It's +conventional to put an empty alternative first and write the comment +`/* empty */' in it. + + The second alternate rule (`input line') handles all nontrivial +input. It means, "After reading any number of lines, read one more +line if possible." The left recursion makes this rule into a loop. +Since the first alternative matches empty input, the loop can be +executed zero or more times. + + The parser function `yyparse' continues to process input until a +grammatical error is seen or the lexical analyzer says there are no more +input tokens; we will arrange for the latter to happen at end-of-input. + + +File: bison.info, Node: Rpcalc Line, Next: Rpcalc Expr, Prev: Rpcalc Input, Up: Rpcalc Rules + +2.1.2.2 Explanation of `line' +............................. + +Now consider the definition of `line': + + line: '\n' + | exp '\n' { printf ("\t%.10g\n", $1); } + ; + + The first alternative is a token which is a newline character; this +means that rpcalc accepts a blank line (and ignores it, since there is +no action). The second alternative is an expression followed by a +newline. This is the alternative that makes rpcalc useful. The +semantic value of the `exp' grouping is the value of `$1' because the +`exp' in question is the first symbol in the alternative. The action +prints this value, which is the result of the computation the user +asked for. + + This action is unusual because it does not assign a value to `$$'. +As a consequence, the semantic value associated with the `line' is +uninitialized (its value will be unpredictable). This would be a bug if +that value were ever used, but we don't use it: once rpcalc has printed +the value of the user's input line, that value is no longer needed. + + +File: bison.info, Node: Rpcalc Expr, Prev: Rpcalc Line, Up: Rpcalc Rules + +2.1.2.3 Explanation of `expr' +............................. + +The `exp' grouping has several rules, one for each kind of expression. +The first rule handles the simplest expressions: those that are just +numbers. The second handles an addition-expression, which looks like +two expressions followed by a plus-sign. The third handles +subtraction, and so on. + + exp: NUM + | exp exp '+' { $$ = $1 + $2; } + | exp exp '-' { $$ = $1 - $2; } + ... + ; + + We have used `|' to join all the rules for `exp', but we could +equally well have written them separately: + + exp: NUM ; + exp: exp exp '+' { $$ = $1 + $2; } ; + exp: exp exp '-' { $$ = $1 - $2; } ; + ... + + Most of the rules have actions that compute the value of the +expression in terms of the value of its parts. For example, in the +rule for addition, `$1' refers to the first component `exp' and `$2' +refers to the second one. The third component, `'+'', has no meaningful +associated semantic value, but if it had one you could refer to it as +`$3'. When `yyparse' recognizes a sum expression using this rule, the +sum of the two subexpressions' values is produced as the value of the +entire expression. *Note Actions::. + + You don't have to give an action for every rule. When a rule has no +action, Bison by default copies the value of `$1' into `$$'. This is +what happens in the first rule (the one that uses `NUM'). + + The formatting shown here is the recommended convention, but Bison +does not require it. You can add or change white space as much as you +wish. For example, this: + + exp : NUM | exp exp '+' {$$ = $1 + $2; } | ... ; + +means the same thing as this: + + exp: NUM + | exp exp '+' { $$ = $1 + $2; } + | ... + ; + +The latter, however, is much more readable. + + +File: bison.info, Node: Rpcalc Lexer, Next: Rpcalc Main, Prev: Rpcalc Rules, Up: RPN Calc + +2.1.3 The `rpcalc' Lexical Analyzer +----------------------------------- + +The lexical analyzer's job is low-level parsing: converting characters +or sequences of characters into tokens. The Bison parser gets its +tokens by calling the lexical analyzer. *Note The Lexical Analyzer +Function `yylex': Lexical. + + Only a simple lexical analyzer is needed for the RPN calculator. +This lexical analyzer skips blanks and tabs, then reads in numbers as +`double' and returns them as `NUM' tokens. Any other character that +isn't part of a number is a separate token. Note that the token-code +for such a single-character token is the character itself. + + The return value of the lexical analyzer function is a numeric code +which represents a token type. The same text used in Bison rules to +stand for this token type is also a C expression for the numeric code +for the type. This works in two ways. If the token type is a +character literal, then its numeric code is that of the character; you +can use the same character literal in the lexical analyzer to express +the number. If the token type is an identifier, that identifier is +defined by Bison as a C macro whose definition is the appropriate +number. In this example, therefore, `NUM' becomes a macro for `yylex' +to use. + + The semantic value of the token (if it has one) is stored into the +global variable `yylval', which is where the Bison parser will look for +it. (The C data type of `yylval' is `YYSTYPE', which was defined at +the beginning of the grammar; *note Declarations for `rpcalc': Rpcalc +Declarations.) + + A token type code of zero is returned if the end-of-input is +encountered. (Bison recognizes any nonpositive value as indicating +end-of-input.) + + Here is the code for the lexical analyzer: + + /* The lexical analyzer returns a double floating point + number on the stack and the token NUM, or the numeric code + of the character read if not a number. It skips all blanks + and tabs, and returns 0 for end-of-input. */ + + #include + + int + yylex (void) + { + int c; + + /* Skip white space. */ + while ((c = getchar ()) == ' ' || c == '\t') + ; + /* Process numbers. */ + if (c == '.' || isdigit (c)) + { + ungetc (c, stdin); + scanf ("%lf", &yylval); + return NUM; + } + /* Return end-of-input. */ + if (c == EOF) + return 0; + /* Return a single char. */ + return c; + } + + +File: bison.info, Node: Rpcalc Main, Next: Rpcalc Error, Prev: Rpcalc Lexer, Up: RPN Calc + +2.1.4 The Controlling Function +------------------------------ + +In keeping with the spirit of this example, the controlling function is +kept to the bare minimum.

It is up to the programmer to supply `yyerror' +(*note Parser C-Language Interface: Interface.), so here is the +definition we will use: + + #include + + /* Called by yyparse on error. */ + void + yyerror (char const *s) + { + fprintf (stderr, "%s\n", s); + } + + After `yyerror' returns, the Bison parser may recover from the error +and continue parsing if the grammar contains a suitable error rule +(*note Error Recovery::). Otherwise, `yyparse' returns nonzero. We +have not written any error rules in this example, so any invalid input +will cause the calculator program to exit. This is not clean behavior +for a real calculator, but it is adequate for the first example. + + +File: bison.info, Node: Rpcalc Generate, Next: Rpcalc Compile, Prev: Rpcalc Error, Up: RPN Calc + +2.1.6 Running Bison to Make the Parser +-------------------------------------- + +Before running Bison to produce a parser, we need to decide how to +arrange all the source code in one or more source files. For such a +simple example, the easiest thing is to put everything in one file. The +definitions of `yylex', `yyerror' and `main' go at the end, in the +epilogue of the file (*note The Overall Layout of a Bison Grammar: +Grammar Layout.). + + For a large project, you would probably have several source files, +and use `make' to arrange to recompile them. + + With all the source in a single file, you use the following command +to convert it into a parser file: + + bison FILE.y + +In this example the file was called `rpcalc.y' (for "Reverse Polish +CALCulator"). Bison produces a file named `FILE.tab.c', removing the +`.y' from the original file name. The file output by Bison contains +the source code for `yyparse'.

The declarations +`%left' and `%right' (right associativity) take the place of `%token' +which is used to declare a token type name without associativity. +(These tokens are single-character literals, which ordinarily don't +need to be declared. We declare them here to specify the +associativity.) + + Operator precedence is determined by the line ordering of the +declarations; the higher the line number of the declaration (lower on +the page or screen), the higher the precedence. Hence, exponentiation +has the highest precedence, unary minus (`NEG') is next, followed by +`*' and `/', and so on. *Note Operator Precedence: Precedence. + + The other important new feature is the `%prec' in the grammar +section for the unary minus operator.

All we have handled is error reporting with `yyerror'. Recall +that by default `yyparse' returns after calling `yyerror'. This means +that an erroneous input line causes the calculator program to exit. +Now we show how to rectify this deficiency. + + The Bison language itself includes the reserved word `error', which +may be included in the grammar rules. In the example below it has been +added to one of the alternatives for `line': + + line: '\n' + | exp '\n' { printf ("\t%.10g\n", $1); } + | error '\n' { yyerrok; } + ; + + This addition to the grammar allows for simple error recovery in the +event of a syntax error. If an expression that cannot be evaluated is +read, the error will be recognized by the third rule for `line', and +parsing will continue. (The `yyerror' function is still called upon to +print its message as well.) The action executes the statement +`yyerrok', a macro defined automatically by Bison; its meaning is that +error recovery is complete (*note Error Recovery::).

In addition, it updates `yylloc', the global variable (of type +`YYLTYPE') containing the token's location. + + Now, each time this function returns a token, the parser has its +number as well as its semantic value, and its location in the text. +The last needed change is to initialize `yylloc', for example in the +controlling function: + + int + main (void) + { + yylloc.first_line = yylloc.last_line = 1; + yylloc.first_column = yylloc.last_column = 0; + return yyparse (); + } + + Remember that computing locations is not a matter of syntax.

It would be nice to have a +calculator that provides other mathematical functions such as `sin', +`cos', etc. + + It is easy to add new operators to the infix calculator as long as +they are only single-character literals.

Its +definition, which is kept in the header `calc.h', is as follows.

The function `putsym' is passed a name and the type +(`VAR' or `FNCT') of the object to be installed. The object is linked +to the front of the list, and a pointer to the object is returned.

Strings of alphanumeric +characters with a leading letter are recognized as either variables or +functions depending on what the symbol table says about them. + + The string is passed to `getsym' for look up in the symbol table. If +the name appears in the table, a pointer to its location and its type +(`VAR' or `FNCT') is returned to `yyparse'. If it is not already in +the table, then it is installed as a `VAR' using `putsym'.

These are copied to the beginning of the parser file so that +they precede the definition of `yyparse'. You can use `#include' to +get the declarations from a header file. If you don't need any C +declarations, you may omit the `%{' and `%}' delimiters that bracket +this section. + + The PROLOGUE section is terminated by the first occurrence of `%}' +that is outside a comment, a string literal, or a character constant. + + You may have more than one PROLOGUE section, intermixed with the +BISON DECLARATIONS. This allows you to have C and Bison declarations +that refer to each other. For example, the `%union' declaration may +use types defined in a header file, and you may wish to prototype +functions that take arguments of type `YYSTYPE'. This can be done with +two PROLOGUE blocks, one before and one after the `%union' declaration. + + %{ + #define _GNU_SOURCE + #include + #include "ptypes.h" + %} + + %union { + long int n; + tree t; /* `tree' is defined in `ptypes.h'. */ + } + + %{ + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(F, N, L) print_token_value (F, N, L) + %} + + ... + + When in doubt, it is usually safer to put prologue code before all +Bison declarations, rather than after. For example, any definitions of +feature test macros like `_GNU_SOURCE' or `_POSIX_C_SOURCE' should +appear before all Bison declarations, as feature test macros can affect +the behavior of Bison-generated `#include' directives. + + +File: bison.info, Node: Prologue Alternatives, Next: Bison Declarations, Prev: Prologue, Up: Grammar Outline + +3.1.2 Prologue Alternatives +--------------------------- + +(The prologue alternatives described here are experimental. More user +feedback will help to determine whether they should become permanent +features.) + + The functionality of PROLOGUE sections can often be subtle and +inflexible. As an alternative, Bison provides a %code directive with +an explicit qualifier field, which identifies the purpose of the code +and thus the location(s) where Bison should generate it. For C/C++, +the qualifier can be omitted for the default location, or it can be one +of `requires', `provides', `top'. *Note %code: Decl Summary. + + Look again at the example of the previous section: + + %{ + #define _GNU_SOURCE + #include + #include "ptypes.h" + %} + + %union { + long int n; + tree t; /* `tree' is defined in `ptypes.h'. */ + } + + %{ + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(F, N, L) print_token_value (F, N, L) + %} + + ... + +Notice that there are two PROLOGUE sections here, but there's a subtle +distinction between their functionality. For example, if you decide to +override Bison's default definition for `YYLTYPE', in which PROLOGUE +section should you write your new definition? You should write it in +the first since Bison will insert that code into the parser source code +file _before_ the default `YYLTYPE' definition. In which PROLOGUE +section should you prototype an internal function, `trace_token', that +accepts `YYLTYPE' and `yytokentype' as arguments? You should prototype +it in the second since Bison will insert that code _after_ the +`YYLTYPE' and `yytokentype' definitions. + + This distinction in functionality between the two PROLOGUE sections +is established by the appearance of the `%union' between them. This +behavior raises a few questions. First, why should the position of a +`%union' affect definitions related to `YYLTYPE' and `yytokentype'? +Second, what if there is no `%union'? In that case, the second kind of +PROLOGUE section is not available. This behavior is not intuitive. + + To avoid this subtle `%union' dependency, rewrite the example using a +`%code top' and an unqualified `%code'. Let's go ahead and add the new +`YYLTYPE' definition and the `trace_token' prototype at the same time: + + %code top { + #define _GNU_SOURCE + #include + + /* WARNING: The following code really belongs + * in a `%code requires'; see below. */ + + #include "ptypes.h" + #define YYLTYPE YYLTYPE + typedef struct YYLTYPE + { + int first_line; + int first_column; + int last_line; + int last_column; + char *filename; + } YYLTYPE; + } + + %union { + long int n; + tree t; /* `tree' is defined in `ptypes.h'. */ + } + + %code { + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(F, N, L) print_token_value (F, N, L) + static void trace_token (enum yytokentype token, YYLTYPE loc); + } + + ... + +In this way, `%code top' and the unqualified `%code' achieve the same +functionality as the two kinds of PROLOGUE sections, but it's always +explicit which kind you intend. Moreover, both kinds are always +available even in the absence of `%union'. + + The `%code top' block above logically contains two parts. The first +two lines before the warning need to appear near the top of the parser +source code file. The first line after the warning is required by +`YYSTYPE' and thus also needs to appear in the parser source code file. +However, if you've instructed Bison to generate a parser header file +(*note %defines: Decl Summary.), you probably want that line to appear +before the `YYSTYPE' definition in that header file as well. The +`YYLTYPE' definition should also appear in the parser header file to +override the default `YYLTYPE' definition there. + + In other words, in the `%code top' block above, all but the first two +lines are dependency code required by the `YYSTYPE' and `YYLTYPE' +definitions. Thus, they belong in one or more `%code requires': + + %code top { + #define _GNU_SOURCE + #include + } + + %code requires { + #include "ptypes.h" + } + %union { + long int n; + tree t; /* `tree' is defined in `ptypes.h'. */ + } + + %code requires { + #define YYLTYPE YYLTYPE + typedef struct YYLTYPE + { + int first_line; + int first_column; + int last_line; + int last_column; + char *filename; + } YYLTYPE; + } + + %code { + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(F, N, L) print_token_value (F, N, L) + static void trace_token (enum yytokentype token, YYLTYPE loc); + } + + ... + +Now Bison will insert `#include "ptypes.h"' and the new `YYLTYPE' +definition before the Bison-generated `YYSTYPE' and `YYLTYPE' +definitions in both the parser source code file and the parser header +file. (By the same reasoning, `%code requires' would also be the +appropriate place to write your own definition for `YYSTYPE'.) + + When you are writing dependency code for `YYSTYPE' and `YYLTYPE', you +should prefer `%code requires' over `%code top' regardless of whether +you instruct Bison to generate a parser header file. When you are +writing code that you need Bison to insert only into the parser source +code file and that has no special need to appear at the top of that +file, you should prefer the unqualified `%code' over `%code top'. +These practices will make the purpose of each block of your code +explicit to Bison and to other developers reading your grammar file. +Following these practices, we expect the unqualified `%code' and `%code +requires' to be the most important of the four PROLOGUE alternatives. + + At some point while developing your parser, you might decide to +provide `trace_token' to modules that are external to your parser. +Thus, you might wish for Bison to insert the prototype into both the +parser header file and the parser source code file. Since this +function is not a dependency required by `YYSTYPE' or `YYLTYPE', it +doesn't make sense to move its prototype to a `%code requires'. More +importantly, since it depends upon `YYLTYPE' and `yytokentype', `%code +requires' is not sufficient. Instead, move its prototype from the +unqualified `%code' to a `%code provides': + + %code top { + #define _GNU_SOURCE + #include + } + + %code requires { + #include "ptypes.h" + } + %union { + long int n; + tree t; /* `tree' is defined in `ptypes.h'. */ + } + + %code requires { + #define YYLTYPE YYLTYPE + typedef struct YYLTYPE + { + int first_line; + int first_column; + int last_line; + int last_column; + char *filename; + } YYLTYPE; + } + + %code provides { + void trace_token (enum yytokentype token, YYLTYPE loc); + } + + %code { + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(F, N, L) print_token_value (F, N, L) + } + + ... + +Bison will insert the `trace_token' prototype into both the parser +header file and the parser source code file after the definitions for +`yytokentype', `YYLTYPE', and `YYSTYPE'. + + The above examples are careful to write directives in an order that +reflects the layout of the generated parser source code and header +files: `%code top', `%code requires', `%code provides', and then +`%code'. While your grammar files may generally be easier to read if +you also follow this order, Bison does not require it. Instead, Bison +lets you choose an organization that makes sense to you. + + You may declare any of these directives multiple times in the +grammar file. In that case, Bison concatenates the contained code in +declaration order. This is the only way in which the position of one +of these directives within the grammar file affects its functionality. + + The result of the previous two properties is greater flexibility in +how you may organize your grammar file. For example, you may organize +semantic-type-related directives by semantic type: + + %code requires { #include "type1.h" } + %union { type1 field1; } + %destructor { type1_free ($$); } + %printer { type1_print ($$); } + + %code requires { #include "type2.h" } + %union { type2 field2; } + %destructor { type2_free ($$); } + %printer { type2_print ($$); } + +You could even place each of the above directive groups in the rules +section of the grammar file next to the set of rules that uses the +associated semantic type. (In the rules section, you must terminate +each of those directives with a semicolon.) And you don't have to +worry that some directive (like a `%union') in the definitions section +is going to adversely affect their functionality in some +counter-intuitive manner just because it comes first. Such an +organization is not possible using PROLOGUE sections. + + This section has been concerned with explaining the advantages of +the four PROLOGUE alternatives over the original Yacc PROLOGUE. +However, in most cases when using these directives, you shouldn't need +to think about all the low-level ordering issues discussed here. +Instead, you should simply use these directives to label each block of +your code according to its purpose and let Bison handle the ordering. +`%code' is the most generic label. Move code to `%code requires', +`%code provides', or `%code top' as needed. + + +File: bison.info, Node: Bison Declarations, Next: Grammar Rules, Prev: Prologue Alternatives, Up: Grammar Outline + +3.1.3 The Bison Declarations Section +------------------------------------ + +The BISON DECLARATIONS section contains declarations that define +terminal and nonterminal symbols, specify precedence, and so on. In +some simple grammars you may not need any declarations. *Note Bison +Declarations: Declarations. + + +File: bison.info, Node: Grammar Rules, Next: Epilogue, Prev: Bison Declarations, Up: Grammar Outline + +3.1.4 The Grammar Rules Section +------------------------------- + +The "grammar rules" section contains one or more Bison grammar rules, +and nothing else. *Note Syntax of Grammar Rules: Rules. + + There must always be at least one grammar rule, and the first `%%' +(which precedes the grammar rules) may never be omitted even if it is +the first thing in the file. + + +File: bison.info, Node: Epilogue, Prev: Grammar Rules, Up: Grammar Outline + +3.1.5 The epilogue +------------------ + +The EPILOGUE is copied verbatim to the end of the parser file, just as +the PROLOGUE is copied to the beginning. This is the most convenient +place to put anything that you want to have in the parser file but +which need not come before the definition of `yyparse'. For example, +the definitions of `yylex' and `yyerror' often go here. Because C +requires functions to be declared before being used, you often need to +declare functions like `yylex' and `yyerror' in the Prologue, even if +you define them in the Epilogue. *Note Parser C-Language Interface: +Interface. + + If the last section is empty, you may omit the `%%' that separates it +from the grammar rules. + + The Bison parser itself contains many macros and identifiers whose +names start with `yy' or `YY', so it is a good idea to avoid using any +such names (except those documented in this manual) in the epilogue of +the grammar file. + + +File: bison.info, Node: Symbols, Next: Rules, Prev: Grammar Outline, Up: Grammar File + +3.2 Symbols, Terminal and Nonterminal +===================================== + +"Symbols" in Bison grammars represent the grammatical classifications +of the language. + + A "terminal symbol" (also known as a "token type") represents a +class of syntactically equivalent tokens. You use the symbol in grammar +rules to mean that a token in that class is allowed. The symbol is +represented in the Bison parser by a numeric code, and the `yylex' +function returns a token type code to indicate what kind of token has +been read. You don't need to know what the code value is; you can use +the symbol to stand for it. + + A "nonterminal symbol" stands for a class of syntactically +equivalent groupings. The symbol name is used in writing grammar rules. +By convention, it should be all lower case. + + Symbol names can contain letters, digits (not at the beginning), +underscores and periods. Periods make sense only in nonterminals. + + There are three ways of writing terminal symbols in the grammar: + + * A "named token type" is written with an identifier, like an + identifier in C. By convention, it should be all upper case. Each + such name must be defined with a Bison declaration such as + `%token'. *Note Token Type Names: Token Decl. + + * A "character token type" (or "literal character token") is written + in the grammar using the same syntax used in C for character + constants; for example, `'+'' is a character token type. A + character token type doesn't need to be declared unless you need to + specify its semantic value data type (*note Data Types of Semantic + Values: Value Type.), associativity, or precedence (*note Operator + Precedence: Precedence.). + + By convention, a character token type is used only to represent a + token that consists of that particular character. Thus, the token + type `'+'' is used to represent the character `+' as a token. + Nothing enforces this convention, but if you depart from it, your + program will confuse other readers. + + All the usual escape sequences used in character literals in C can + be used in Bison as well, but you must not use the null character + as a character literal because its numeric code, zero, signifies + end-of-input (*note Calling Convention for `yylex': Calling + Convention.). Also, unlike standard C, trigraphs have no special + meaning in Bison character literals, nor is backslash-newline + allowed. + + * A "literal string token" is written like a C string constant; for + example, `"<="' is a literal string token. A literal string token + doesn't need to be declared unless you need to specify its semantic + value data type (*note Value Type::), associativity, or precedence + (*note Precedence::). + + You can associate the literal string token with a symbolic name as + an alias, using the `%token' declaration (*note Token + Declarations: Token Decl.). If you don't do that, the lexical + analyzer has to retrieve the token number for the literal string + token from the `yytname' table (*note Calling Convention::). + + *Warning*: literal string tokens do not work in Yacc. + + By convention, a literal string token is used only to represent a + token that consists of that particular string. Thus, you should + use the token type `"<="' to represent the string `<=' as a token. + Bison does not enforce this convention, but if you depart from it, + people who read your program will be confused. + + All the escape sequences used in string literals in C can be used + in Bison as well, except that you must not use a null character + within a string literal. Also, unlike Standard C, trigraphs have + no special meaning in Bison string literals, nor is + backslash-newline allowed. A literal string token must contain + two or more characters; for a token containing just one character, + use a character token (see above). + + How you choose to write a terminal symbol has no effect on its +grammatical meaning. That depends only on where it appears in rules and +on when the parser function returns that symbol. + + The value returned by `yylex' is always one of the terminal symbols, +except that a zero or negative value signifies end-of-input. Whichever +way you write the token type in the grammar rules, you write it the +same way in the definition of `yylex'. The numeric code for a +character token type is simply the positive numeric code of the +character, so `yylex' can use the identical value to generate the +requisite code, though you may need to convert it to `unsigned char' to +avoid sign-extension on hosts where `char' is signed. Each named token +type becomes a C macro in the parser file, so `yylex' can use the name +to stand for the code. (This is why periods don't make sense in +terminal symbols.) *Note Calling Convention for `yylex': Calling +Convention. + + If `yylex' is defined in a separate file, you need to arrange for the +token-type macro definitions to be available there. Use the `-d' +option when you run Bison, so that it will write these macro definitions +into a separate header file `NAME.tab.h' which you can include in the +other source files that need it. *Note Invoking Bison: Invocation. + + If you want to write a grammar that is portable to any Standard C +host, you must use only nonnull character tokens taken from the basic +execution character set of Standard C. This set consists of the ten +digits, the 52 lower- and upper-case English letters, and the +characters in the following C-language string: + + "\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_{|}~" + + The `yylex' function and Bison must use a consistent character set +and encoding for character tokens. For example, if you run Bison in an +ASCII environment, but then compile and run the resulting program in an +environment that uses an incompatible character set like EBCDIC, the +resulting program may not work because the tables generated by Bison +will assume ASCII numeric values for character tokens. It is standard +practice for software distributions to contain C source files that were +generated by Bison in an ASCII environment, so installers on platforms +that are incompatible with ASCII must rebuild those files before +compiling them. + + The symbol `error' is a terminal symbol reserved for error recovery +(*note Error Recovery::); you shouldn't use it for any other purpose. +In particular, `yylex' should never return this value. The default +value of the error token is 256, unless you explicitly assigned 256 to +one of your tokens with a `%token' declaration. + + +File: bison.info, Node: Rules, Next: Recursion, Prev: Symbols, Up: Grammar File + +3.3 Syntax of Grammar Rules +=========================== + +A Bison grammar rule has the following general form: + + RESULT: COMPONENTS... + ; + +where RESULT is the nonterminal symbol that this rule describes, and +COMPONENTS are various terminal and nonterminal symbols that are put +together by this rule (*note Symbols::). + + For example, + + exp: exp '+' exp + ; + +says that two groupings of type `exp', with a `+' token in between, can +be combined into a larger grouping of type `exp'. + + White space in rules is significant only to separate symbols. You +can add extra white space as you wish. + + Scattered among the components can be ACTIONS that determine the +semantics of the rule. An action looks like this: + + {C STATEMENTS} + +This is an example of "braced code", that is, C code surrounded by +braces, much like a compound statement in C. Braced code can contain +any sequence of C tokens, so long as its braces are balanced. Bison +does not check the braced code for correctness directly; it merely +copies the code to the output file, where the C compiler can check it. + + Within braced code, the balanced-brace count is not affected by +braces within comments, string literals, or character constants, but it +is affected by the C digraphs `<%' and `%>' that represent braces. At +the top level braced code must be terminated by `}' and not by a +digraph. Bison does not look for trigraphs, so if braced code uses +trigraphs you should ensure that they do not affect the nesting of +braces or the boundaries of comments, string literals, or character +constants. + + Usually there is only one action and it follows the components. +*Note Actions::. + + Multiple rules for the same RESULT can be written separately or can +be joined with the vertical-bar character `|' as follows: + + RESULT: RULE1-COMPONENTS... + | RULE2-COMPONENTS... + ... + ; + +They are still considered distinct rules even when joined in this way. + + If COMPONENTS in a rule is empty, it means that RESULT can match the +empty string. For example, here is how to define a comma-separated +sequence of zero or more `exp' groupings: + + expseq: /* empty */ + | expseq1 + ; + + expseq1: exp + | expseq1 ',' exp + ; + +It is customary to write a comment `/* empty */' in each rule with no +components. + + +File: bison.info, Node: Recursion, Next: Semantics, Prev: Rules, Up: Grammar File + +3.4 Recursive Rules +=================== + +A rule is called "recursive" when its RESULT nonterminal appears also +on its right hand side. Nearly all Bison grammars need to use +recursion, because that is the only way to define a sequence of any +number of a particular thing. Consider this recursive definition of a +comma-separated sequence of one or more expressions: + + expseq1: exp + | expseq1 ',' exp + ; + +Since the recursive use of `expseq1' is the leftmost symbol in the +right hand side, we call this "left recursion". By contrast, here the +same construct is defined using "right recursion": + + expseq1: exp + | exp ',' expseq1 + ; + +Any kind of sequence can be defined using either left recursion or right +recursion, but you should always use left recursion, because it can +parse a sequence of any number of elements with bounded stack space. +Right recursion uses up space on the Bison stack in proportion to the +number of elements in the sequence, because all the elements must be +shifted onto the stack before the rule can be applied even once. *Note +The Bison Parser Algorithm: Algorithm, for further explanation of this. + + "Indirect" or "mutual" recursion occurs when the result of the rule +does not appear directly on its right hand side, but does appear in +rules for other nonterminals which do appear on its right hand side. + + For example: + + expr: primary + | primary '+' primary + ; + + primary: constant + | '(' expr ')' + ; + +defines two mutually-recursive nonterminals, since each refers to the +other. + + +File: bison.info, Node: Semantics, Next: Locations, Prev: Recursion, Up: Grammar File + +3.5 Defining Language Semantics +=============================== + +The grammar rules for a language determine only the syntax. The +semantics are determined by the semantic values associated with various +tokens and groupings, and by the actions taken when various groupings +are recognized. + + For example, the calculator calculates properly because the value +associated with each expression is the proper number; it adds properly +because the action for the grouping `X + Y' is to add the numbers +associated with X and Y. + +* Menu: + +* Value Type:: Specifying one data type for all semantic values. +* Multiple Types:: Specifying several alternative data types. +* Actions:: An action is the semantic definition of a grammar rule. +* Action Types:: Specifying data types for actions to operate on. +* Mid-Rule Actions:: Most actions go at the end of a rule. + This says when, why and how to use the exceptional + action in the middle of a rule. + + +File: bison.info, Node: Value Type, Next: Multiple Types, Up: Semantics + +3.5.1 Data Types of Semantic Values +----------------------------------- + +In a simple program it may be sufficient to use the same data type for +the semantic values of all language constructs. This was true in the +RPN and infix calculator examples (*note Reverse Polish Notation +Calculator: RPN Calc.). + + Bison normally uses the type `int' for semantic values if your +program uses the same data type for all language constructs. To +specify some other type, define `YYSTYPE' as a macro, like this: + + #define YYSTYPE double + +`YYSTYPE''s replacement list should be a type name that does not +contain parentheses or square brackets. This macro definition must go +in the prologue of the grammar file (*note Outline of a Bison Grammar: +Grammar Outline.). + + +File: bison.info, Node: Multiple Types, Next: Actions, Prev: Value Type, Up: Semantics + +3.5.2 More Than One Value Type +------------------------------ + +In most programs, you will need different data types for different kinds +of tokens and groupings. For example, a numeric constant may need type +`int' or `long int', while a string constant needs type `char *', and +an identifier might need a pointer to an entry in the symbol table. + + To use more than one data type for semantic values in one parser, +Bison requires you to do two things: + + * Specify the entire collection of possible data types, either by + using the `%union' Bison declaration (*note The Collection of + Value Types: Union Decl.), or by using a `typedef' or a `#define' + to define `YYSTYPE' to be a union type whose member names are the + type tags. + + * Choose one of those types for each symbol (terminal or + nonterminal) for which semantic values are used. This is done for + tokens with the `%token' Bison declaration (*note Token Type + Names: Token Decl.) and for groupings with the `%type' Bison + declaration (*note Nonterminal Symbols: Type Decl.). + + +File: bison.info, Node: Actions, Next: Action Types, Prev: Multiple Types, Up: Semantics + +3.5.3 Actions +------------- + +An action accompanies a syntactic rule and contains C code to be +executed each time an instance of that rule is recognized. The task of +most actions is to compute a semantic value for the grouping built by +the rule from the semantic values associated with tokens or smaller +groupings. + + An action consists of braced code containing C statements, and can be +placed at any position in the rule; it is executed at that position. +Most rules have just one action at the end of the rule, following all +the components. Actions in the middle of a rule are tricky and used +only for special purposes (*note Actions in Mid-Rule: Mid-Rule +Actions.). + + The C code in an action can refer to the semantic values of the +components matched by the rule with the construct `$N', which stands for +the value of the Nth component. The semantic value for the grouping +being constructed is `$$'. Bison translates both of these constructs +into expressions of the appropriate type when it copies the actions +into the parser file. `$$' is translated to a modifiable lvalue, so it +can be assigned to. + + Here is a typical example: + + exp: ... + | exp '+' exp + { $$ = $1 + $3; } + +This rule constructs an `exp' from two smaller `exp' groupings +connected by a plus-sign token. In the action, `$1' and `$3' refer to +the semantic values of the two component `exp' groupings, which are the +first and third symbols on the right hand side of the rule. The sum is +stored into `$$' so that it becomes the semantic value of the +addition-expression just recognized by the rule. If there were a +useful semantic value associated with the `+' token, it could be +referred to as `$2'. + + Note that the vertical-bar character `|' is really a rule separator, +and actions are attached to a single rule. This is a difference with +tools like Flex, for which `|' stands for either "or", or "the same +action as that of the next rule". In the following example, the action +is triggered only when `b' is found: + + a-or-b: 'a'|'b' { a_or_b_found = 1; }; + + If you don't specify an action for a rule, Bison supplies a default: +`$$ = $1'. Thus, the value of the first symbol in the rule becomes the +value of the whole rule. Of course, the default action is valid only +if the two data types match. There is no meaningful default action for +an empty rule; every empty rule must have an explicit action unless the +rule's value does not matter. + + `$N' with N zero or negative is allowed for reference to tokens and +groupings on the stack _before_ those that match the current rule. +This is a very risky practice, and to use it reliably you must be +certain of the context in which the rule is applied. Here is a case in +which you can use this reliably: + + foo: expr bar '+' expr { ... } + | expr bar '-' expr { ... } + ; + + bar: /* empty */ + { previous_expr = $0; } + ; + + As long as `bar' is used only in the fashion shown here, `$0' always +refers to the `expr' which precedes `bar' in the definition of `foo'. + + It is also possible to access the semantic value of the lookahead +token, if any, from a semantic action. This semantic value is stored +in `yylval'. *Note Special Features for Use in Actions: Action +Features. + + +File: bison.info, Node: Action Types, Next: Mid-Rule Actions, Prev: Actions, Up: Semantics + +3.5.4 Data Types of Values in Actions +------------------------------------- + +If you have chosen a single data type for semantic values, the `$$' and +`$N' constructs always have that data type. + + If you have used `%union' to specify a variety of data types, then +you must declare a choice among these types for each terminal or +nonterminal symbol that can have a semantic value. Then each time you +use `$$' or `$N', its data type is determined by which symbol it refers +to in the rule. In this example, + + exp: ... + | exp '+' exp + { $$ = $1 + $3; } + +`$1' and `$3' refer to instances of `exp', so they all have the data +type declared for the nonterminal symbol `exp'. If `$2' were used, it +would have the data type declared for the terminal symbol `'+'', +whatever that might be. + + Alternatively, you can specify the data type when you refer to the +value, by inserting `' after the `$' at the beginning of the +reference. For example, if you have defined types as shown here: + + %union { + int itype; + double dtype; + } + +then you can write `$1' to refer to the first subunit of the +rule as an integer, or `$1' to refer to it as a double. + + +File: bison.info, Node: Mid-Rule Actions, Prev: Action Types, Up: Semantics + +3.5.5 Actions in Mid-Rule +------------------------- + +Occasionally it is useful to put an action in the middle of a rule. +These actions are written just like usual end-of-rule actions, but they +are executed before the parser even recognizes the following components. + + A mid-rule action may refer to the components preceding it using +`$N', but it may not refer to subsequent components because it is run +before they are parsed. + + The mid-rule action itself counts as one of the components of the +rule. This makes a difference when there is another action later in +the same rule (and usually there is another at the end): you have to +count the actions along with the symbols when working out which number +N to use in `$N'. + + The mid-rule action can also have a semantic value. The action can +set its value with an assignment to `$$', and actions later in the rule +can refer to the value using `$N'. Since there is no symbol to name +the action, there is no way to declare a data type for the value in +advance, so you must use the `$<...>N' construct to specify a data type +each time you refer to this value. + + There is no way to set the value of the entire rule with a mid-rule +action, because assignments to `$$' do not have that effect. The only +way to set the value for the entire rule is with an ordinary action at +the end of the rule. + + Here is an example from a hypothetical compiler, handling a `let' +statement that looks like `let (VARIABLE) STATEMENT' and serves to +create a variable named VARIABLE temporarily for the duration of +STATEMENT. To parse this construct, we must put VARIABLE into the +symbol table while STATEMENT is parsed, then remove it afterward. Here +is how it is done: + + stmt: LET '(' var ')' + { $$ = push_context (); + declare_variable ($3); } + stmt { $$ = $6; + pop_context ($5); } + +As soon as `let (VARIABLE)' has been recognized, the first action is +run. It saves a copy of the current semantic context (the list of +accessible variables) as its semantic value, using alternative +`context' in the data-type union. Then it calls `declare_variable' to +add the new variable to that list. Once the first action is finished, +the embedded statement `stmt' can be parsed. Note that the mid-rule +action is component number 5, so the `stmt' is component number 6. + + After the embedded statement is parsed, its semantic value becomes +the value of the entire `let'-statement. Then the semantic value from +the earlier action is used to restore the prior list of variables. This +removes the temporary `let'-variable from the list so that it won't +appear to exist while the rest of the program is parsed. + + In the above example, if the parser initiates error recovery (*note +Error Recovery::) while parsing the tokens in the embedded statement +`stmt', it might discard the previous semantic context `$5' +without restoring it. Thus, `$5' needs a destructor (*note +Freeing Discarded Symbols: Destructor Decl.). However, Bison currently +provides no means to declare a destructor specific to a particular +mid-rule action's semantic value. + + One solution is to bury the mid-rule action inside a nonterminal +symbol and to declare a destructor for that symbol: + + %type let + %destructor { pop_context ($$); } let + + %% + + stmt: let stmt + { $$ = $2; + pop_context ($1); } + ; + + let: LET '(' var ')' + { $$ = push_context (); + declare_variable ($3); } + ; + +Note that the action is now at the end of its rule. Any mid-rule +action can be converted to an end-of-rule action in this way, and this +is what Bison actually does to implement mid-rule actions. + + Taking action before a rule is completely recognized often leads to +conflicts since the parser must commit to a parse in order to execute +the action. For example, the following two rules, without mid-rule +actions, can coexist in a working parser because the parser can shift +the open-brace token and look at what follows before deciding whether +there is a declaration or not: + + compound: '{' declarations statements '}' + | '{' statements '}' + ; + +But when we add a mid-rule action as follows, the rules become +nonfunctional: + + compound: { prepare_for_local_variables (); } + '{' declarations statements '}' + | '{' statements '}' + ; + +Now the parser is forced to decide whether to run the mid-rule action +when it has read no farther than the open-brace. In other words, it +must commit to using one rule or the other, without sufficient +information to do it correctly. (The open-brace token is what is called +the "lookahead" token at this time, since the parser is still deciding +what to do about it. *Note Lookahead Tokens: Lookahead.) + + You might think that you could correct the problem by putting +identical actions into the two rules, like this: + + compound: { prepare_for_local_variables (); } + '{' declarations statements '}' + | { prepare_for_local_variables (); } + '{' statements '}' + ; + +But this does not help, because Bison does not realize that the two +actions are identical. (Bison never tries to understand the C code in +an action.) + + If the grammar is such that a declaration can be distinguished from a +statement by the first token (which is true in C), then one solution +which does work is to put the action after the open-brace, like this: + + compound: '{' { prepare_for_local_variables (); } + declarations statements '}' + | '{' statements '}' + ; + +Now the first token of the following declaration or statement, which +would in any case tell Bison which rule to use, can still do so. + + Another solution is to bury the action inside a nonterminal symbol +which serves as a subroutine: + + subroutine: /* empty */ + { prepare_for_local_variables (); } + ; + + compound: subroutine + '{' declarations statements '}' + | subroutine + '{' statements '}' + ; + +Now Bison can execute the action in the rule for `subroutine' without +deciding which rule for `compound' it will eventually use. + + +File: bison.info, Node: Locations, Next: Declarations, Prev: Semantics, Up: Grammar File + +3.6 Tracking Locations +====================== + +Though grammar rules and semantic actions are enough to write a fully +functional parser, it can be useful to process some additional +information, especially symbol locations. + + The way locations are handled is defined by providing a data type, +and actions to take when rules are matched. + +* Menu: + +* Location Type:: Specifying a data type for locations. +* Actions and Locations:: Using locations in actions. +* Location Default Action:: Defining a general way to compute locations. + + +File: bison.info, Node: Location Type, Next: Actions and Locations, Up: Locations + +3.6.1 Data Type of Locations +---------------------------- + +Defining a data type for locations is much simpler than for semantic +values, since all tokens and groupings always use the same type. + + You can specify the type of locations by defining a macro called +`YYLTYPE', just as you can specify the semantic value type by defining +a `YYSTYPE' macro (*note Value Type::). When `YYLTYPE' is not defined, +Bison uses a default structure type with four members: + + typedef struct YYLTYPE + { + int first_line; + int first_column; + int last_line; + int last_column; + } YYLTYPE; + + At the beginning of the parsing, Bison initializes all these fields +to 1 for `yylloc'. + + +File: bison.info, Node: Actions and Locations, Next: Location Default Action, Prev: Location Type, Up: Locations + +3.6.2 Actions and Locations +--------------------------- + +Actions are not only useful for defining language semantics, but also +for describing the behavior of the output parser with locations. + + The most obvious way for building locations of syntactic groupings +is very similar to the way semantic values are computed. In a given +rule, several constructs can be used to access the locations of the +elements being matched. The location of the Nth component of the right +hand side is `@N', while the location of the left hand side grouping is +`@$'. + + Here is a basic example using the default data type for locations: + + exp: ... + | exp '/' exp + { + @$.first_column = @1.first_column; + @$.first_line = @1.first_line; + @$.last_column = @3.last_column; + @$.last_line = @3.last_line; + if ($3) + $$ = $1 / $3; + else + { + $$ = 1; + fprintf (stderr, + "Division by zero, l%d,c%d-l%d,c%d", + @3.first_line, @3.first_column, + @3.last_line, @3.last_column); + } + } + + As for semantic values, there is a default action for locations that +is run each time a rule is matched. It sets the beginning of `@$' to +the beginning of the first symbol, and the end of `@$' to the end of the +last symbol. + + With this default action, the location tracking can be fully +automatic. The example above simply rewrites this way: + + exp: ... + | exp '/' exp + { + if ($3) + $$ = $1 / $3; + else + { + $$ = 1; + fprintf (stderr, + "Division by zero, l%d,c%d-l%d,c%d", + @3.first_line, @3.first_column, + @3.last_line, @3.last_column); + } + } + + It is also possible to access the location of the lookahead token, +if any, from a semantic action. This location is stored in `yylloc'. +*Note Special Features for Use in Actions: Action Features. + + +File: bison.info, Node: Location Default Action, Prev: Actions and Locations, Up: Locations + +3.6.3 Default Action for Locations +---------------------------------- + +Actually, actions are not the best place to compute locations. Since +locations are much more general than semantic values, there is room in +the output parser to redefine the default action to take for each rule. +The `YYLLOC_DEFAULT' macro is invoked each time a rule is matched, +before the associated action is run. It is also invoked while +processing a syntax error, to compute the error's location. Before +reporting an unresolvable syntactic ambiguity, a GLR parser invokes +`YYLLOC_DEFAULT' recursively to compute the location of that ambiguity. + + Most of the time, this macro is general enough to suppress location +dedicated code from semantic actions. + + The `YYLLOC_DEFAULT' macro takes three parameters. The first one is +the location of the grouping (the result of the computation). When a +rule is matched, the second parameter identifies locations of all right +hand side elements of the rule being matched, and the third parameter +is the size of the rule's right hand side. When a GLR parser reports +an ambiguity, which of multiple candidate right hand sides it passes to +`YYLLOC_DEFAULT' is undefined. When processing a syntax error, the +second parameter identifies locations of the symbols that were +discarded during error processing, and the third parameter is the +number of discarded symbols. + + By default, `YYLLOC_DEFAULT' is defined this way: + + # define YYLLOC_DEFAULT(Current, Rhs, N) \ + do \ + if (N) \ + { \ + (Current).first_line = YYRHSLOC(Rhs, 1).first_line; \ + (Current).first_column = YYRHSLOC(Rhs, 1).first_column; \ + (Current).last_line = YYRHSLOC(Rhs, N).last_line; \ + (Current).last_column = YYRHSLOC(Rhs, N).last_column; \ + } \ + else \ + { \ + (Current).first_line = (Current).last_line = \ + YYRHSLOC(Rhs, 0).last_line; \ + (Current).first_column = (Current).last_column = \ + YYRHSLOC(Rhs, 0).last_column; \ + } \ + while (0) + + where `YYRHSLOC (rhs, k)' is the location of the Kth symbol in RHS +when K is positive, and the location of the symbol just before the +reduction when K and N are both zero. + + When defining `YYLLOC_DEFAULT', you should consider that: + + * All arguments are free of side-effects. However, only the first + one (the result) should be modified by `YYLLOC_DEFAULT'. + + * For consistency with semantic actions, valid indexes within the + right hand side range from 1 to N.

Nonterminal symbols must be +declared if you need to specify which data type to use for the semantic +value (*note More Than One Value Type: Multiple Types.). + + The first rule in the file also specifies the start symbol, by +default.

If +the requirement is not met, `bison' exits with an error (exit status +63). + + %require "VERSION" + + +File: bison.info, Node: Token Decl, Next: Precedence Decl, Prev: Require Decl, Up: Declarations + +3.7.2 Token Type Names +---------------------- + +The basic way to declare a token type name (terminal symbol) is as +follows: + + %token NAME + + Bison will convert this into a `#define' directive in the parser, so +that the function `yylex' (if it is in this file) can use the name NAME +to stand for this token type's code. + + Alternatively, you can use `%left', `%right', or `%nonassoc' instead +of `%token', if you wish to specify associativity and precedence. +*Note Operator Precedence: Precedence Decl. + + You can explicitly specify the numeric code for a token type by +appending a nonnegative decimal or hexadecimal integer value in the +field immediately following the token name: + + %token NUM 300 + %token XNUM 0x12d // a GNU extension + +It is generally best, however, to let Bison choose the numeric codes for +all token types. Bison will automatically select codes that don't +conflict with each other or with normal characters. + + In the event that the stack type is a union, you must augment the +`%token' or other token declaration to include the data type +alternative delimited by angle-brackets (*note More Than One Value +Type: Multiple Types.). + + For example: + + %union { /* define stack type */ + double val; + symrec *tptr; + } + %token NUM /* define token NUM and its type */ + + You can associate a literal string token with a token type name by +writing the literal string at the end of a `%token' declaration which +declares the name. For example: + + %token arrow "=>" + +For example, a grammar for the C language might specify these names with +equivalent literal string tokens: + + %token OR "||" + %token LE 134 "<=" + %left OR "<=" + +Once you equate the literal string and the token name, you can use them +interchangeably in further declarations or the grammar rules. The +`yylex' function can use the token name or the literal string to obtain +the token type code number (*note Calling Convention::). Syntax error +messages passed to `yyerror' from the parser will reference the literal +string instead of the token name. + + The token numbered as 0 corresponds to end of file; the following +line allows for nicer error messages referring to "end of file" instead +of "$end": + + %token END 0 "end of file" + + +File: bison.info, Node: Precedence Decl, Next: Union Decl, Prev: Token Decl, Up: Declarations + +3.7.3 Operator Precedence +------------------------- + +Use the `%left', `%right' or `%nonassoc' declaration to declare a token +and specify its precedence and associativity, all at once. These are +called "precedence declarations". *Note Operator Precedence: +Precedence, for general information on operator precedence. + + The syntax of a precedence declaration is nearly the same as that of +`%token': either + + %left SYMBOLS... + +or + + %left SYMBOLS... + + And indeed any of these declarations serves the purposes of `%token'. +But in addition, they specify the associativity and relative precedence +for all the SYMBOLS: + + * The associativity of an operator OP determines how repeated uses + of the operator nest: whether `X OP Y OP Z' is parsed by grouping + X with Y first or by grouping Y with Z first. `%left' specifies + left-associativity (grouping X with Y first) and `%right' + specifies right-associativity (grouping Y with Z first). + `%nonassoc' specifies no associativity, which means that `X OP Y + OP Z' is considered a syntax error. + + * The precedence of an operator determines how it nests with other + operators. All the tokens declared in a single precedence + declaration have equal precedence and nest together according to + their associativity. When two tokens declared in different + precedence declarations associate, the one declared later has the + higher precedence and is grouped first. + + For backward compatibility, there is a confusing difference between +the argument lists of `%token' and precedence declarations. Only a +`%token' can associate a literal string with a token type name. A +precedence declaration always interprets a literal string as a +reference to a separate token. For example: + + %left OR "<=" // Does not declare an alias. + %left OR 134 "<=" 135 // Declares 134 for OR and 135 for "<=". + + +File: bison.info, Node: Union Decl, Next: Type Decl, Prev: Precedence Decl, Up: Declarations + +3.7.4 The Collection of Value Types +----------------------------------- + +The `%union' declaration specifies the entire collection of possible +data types for semantic values. The keyword `%union' is followed by +braced code containing the same thing that goes inside a `union' in C. + + For example: + + %union { + double val; + symrec *tptr; + } + +This says that the two alternative types are `double' and `symrec *'. +They are given names `val' and `tptr'; these names are used in the +`%token' and `%type' declarations to pick one of the types for a +terminal or nonterminal symbol (*note Nonterminal Symbols: Type Decl.). + + As an extension to POSIX, a tag is allowed after the `union'. For +example: + + %union value { + double val; + symrec *tptr; + } + +specifies the union tag `value', so the corresponding C type is `union +value'. If you do not specify a tag, it defaults to `YYSTYPE'. + + As another extension to POSIX, you may specify multiple `%union' +declarations; their contents are concatenated. However, only the first +`%union' declaration can specify a tag. + + Note that, unlike making a `union' declaration in C, you need not +write a semicolon after the closing brace. + + Instead of `%union', you can define and use your own union type +`YYSTYPE' if your grammar contains at least one `' tag. For +example, you can put the following into a header file `parser.h': + + union YYSTYPE { + double val; + symrec *tptr; + }; + typedef union YYSTYPE YYSTYPE; + +and then your grammar can use the following instead of `%union': + + %{ + #include "parser.h" + %} + %type expr + %token ID + + +File: bison.info, Node: Type Decl, Next: Initial Action Decl, Prev: Union Decl, Up: Declarations + +3.7.5 Nonterminal Symbols +------------------------- + +When you use `%union' to specify multiple value types, you must declare +the value type of each nonterminal symbol for which values are used. +This is done with a `%type' declaration, like this: + + %type NONTERMINAL... + +Here NONTERMINAL is the name of a nonterminal symbol, and TYPE is the +name given in the `%union' to the alternative that you want (*note The +Collection of Value Types: Union Decl.). You can give any number of +nonterminal symbols in the same `%type' declaration, if they have the +same value type. Use spaces to separate the symbol names. + + You can also declare the value type of a terminal symbol. To do +this, use the same `' construction in a declaration for the +terminal symbol. All kinds of token declarations allow `'. + + +File: bison.info, Node: Initial Action Decl, Next: Destructor Decl, Prev: Type Decl, Up: Declarations + +3.7.6 Performing Actions before Parsing +--------------------------------------- + +Sometimes your parser needs to perform some initializations before +parsing. The `%initial-action' directive allows for such arbitrary +code. + + -- Directive: %initial-action { CODE } + Declare that the braced CODE must be invoked before parsing each + time `yyparse' is called. The CODE may use `$$' and `@$' -- + initial value and location of the lookahead -- and the + `%parse-param'. + + For instance, if your locations use a file name, you may use + + %parse-param { char const *file_name }; + %initial-action + { + @$.initialize (file_name); + }; + + +File: bison.info, Node: Destructor Decl, Next: Expect Decl, Prev: Initial Action Decl, Up: Declarations + +3.7.7 Freeing Discarded Symbols +------------------------------- + +During error recovery (*note Error Recovery::), symbols already pushed +on the stack and tokens coming from the rest of the file are discarded +until the parser falls on its feet. If the parser runs out of memory, +or if it returns via `YYABORT' or `YYACCEPT', all the symbols on the +stack must be discarded. Even if the parser succeeds, it must discard +the start symbol. + + When discarded symbols convey heap based information, this memory is +lost. While this behavior can be tolerable for batch parsers, such as +in traditional compilers, it is unacceptable for programs like shells or +protocol implementations that may parse and execute indefinitely. + + The `%destructor' directive defines code that is called when a +symbol is automatically discarded. + + -- Directive: %destructor { CODE } SYMBOLS + Invoke the braced CODE whenever the parser discards one of the + SYMBOLS. Within CODE, `$$' designates the semantic value + associated with the discarded symbol, and `@$' designates its + location. The additional parser parameters are also available + (*note The Parser Function `yyparse': Parser Function.). + + When a symbol is listed among SYMBOLS, its `%destructor' is called + a per-symbol `%destructor'. You may also define a per-type + `%destructor' by listing a semantic type tag among SYMBOLS. In + that case, the parser will invoke this CODE whenever it discards + any grammar symbol that has that semantic type tag unless that + symbol has its own per-symbol `%destructor'. + + Finally, you can define two different kinds of default + `%destructor's. (These default forms are experimental. More user + feedback will help to determine whether they should become + permanent features.) You can place each of `<*>' and `<>' in the + SYMBOLS list of exactly one `%destructor' declaration in your + grammar file. The parser will invoke the CODE associated with one + of these whenever it discards any user-defined grammar symbol that + has no per-symbol and no per-type `%destructor'. The parser uses + the CODE for `<*>' in the case of such a grammar symbol for which + you have formally declared a semantic type tag (`%type' counts as + such a declaration, but `$$' does not). The parser uses the + CODE for `<>' in the case of such a grammar symbol that has no + declared semantic type tag. + +For example: + + %union { char *string; } + %token STRING1 + %token STRING2 + %type string1 + %type string2 + %union { char character; } + %token CHR + %type chr + %token TAGLESS + + %destructor { } + %destructor { free ($$); } <*> + %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1 + %destructor { printf ("Discarding tagless symbol.\n"); } <> + +guarantees that, when the parser discards any user-defined symbol that +has a semantic type tag other than `', it passes its +semantic value to `free' by default. However, when the parser discards +a `STRING1' or a `string1', it also prints its line number to `stdout'. +It performs only the second `%destructor' in this case, so it invokes +`free' only once. Finally, the parser merely prints a message whenever +it discards any symbol, such as `TAGLESS', that has no semantic type +tag. + + A Bison-generated parser invokes the default `%destructor's only for +user-defined as opposed to Bison-defined symbols. For example, the +parser will not invoke either kind of default `%destructor' for the +special Bison-defined symbols `$accept', `$undefined', or `$end' (*note +Bison Symbols: Table of Symbols.), none of which you can reference in +your grammar. It also will not invoke either for the `error' token +(*note error: Table of Symbols.), which is always defined by Bison +regardless of whether you reference it in your grammar. However, it +may invoke one of them for the end token (token 0) if you redefine it +from `$end' to, for example, `END': + + %token END 0 + + Finally, Bison will never invoke a `%destructor' for an unreferenced +mid-rule semantic value (*note Actions in Mid-Rule: Mid-Rule Actions.). +That is, Bison does not consider a mid-rule to have a semantic value if +you do not reference `$$' in the mid-rule's action or `$N' (where N is +the RHS symbol position of the mid-rule) in any later action in that +rule. However, if you do reference either, the Bison-generated parser +will invoke the `<>' `%destructor' whenever it discards the mid-rule +symbol. + + + "Discarded symbols" are the following: + + * stacked symbols popped during the first phase of error recovery, + + * incoming terminals during the second phase of error recovery, + + * the current lookahead and the entire stack (except the current + right-hand side symbols) when the parser returns immediately, and + + * the start symbol, when the parser succeeds. + + The parser can "return immediately" because of an explicit call to +`YYABORT' or `YYACCEPT', or failed error recovery, or memory exhaustion. + + Right-hand side symbols of a rule that explicitly triggers a syntax +error via `YYERROR' are not discarded automatically. As a rule of +thumb, destructors are invoked only when user actions cannot manage the +memory. + + +File: bison.info, Node: Expect Decl, Next: Start Decl, Prev: Destructor Decl, Up: Declarations + +3.7.8 Suppressing Conflict Warnings +----------------------------------- + +Bison normally warns if there are any conflicts in the grammar (*note +Shift/Reduce Conflicts: Shift/Reduce.), but most real grammars have +harmless shift/reduce conflicts which are resolved in a predictable way +and would be difficult to eliminate. It is desirable to suppress the +warning about these conflicts unless the number of conflicts changes. +You can do this with the `%expect' declaration. + + The declaration looks like this: + + %expect N + + Here N is a decimal integer. The declaration says there should be N +shift/reduce conflicts and no reduce/reduce conflicts. Bison reports +an error if the number of shift/reduce conflicts differs from N, or if +there are any reduce/reduce conflicts. + + For normal LALR(1) parsers, reduce/reduce conflicts are more +serious, and should be eliminated entirely. Bison will always report +reduce/reduce conflicts for these parsers. With GLR parsers, however, +both kinds of conflicts are routine; otherwise, there would be no need +to use GLR parsing. Therefore, it is also possible to specify an +expected number of reduce/reduce conflicts in GLR parsers, using the +declaration: + + %expect-rr N + + In general, using `%expect' involves these steps: + + * Compile your grammar without `%expect'. Use the `-v' option to + get a verbose list of where the conflicts occur. Bison will also + print the number of conflicts. + + * Check each of the conflicts to make sure that Bison's default + resolution is what you really want. If not, rewrite the grammar + and go back to the beginning. + + * Add an `%expect' declaration, copying the number N from the number + which Bison printed. With GLR parsers, add an `%expect-rr' + declaration as well. + + Now Bison will warn you if you introduce an unexpected conflict, but +will keep silent otherwise. + + +File: bison.info, Node: Start Decl, Next: Pure Decl, Prev: Expect Decl, Up: Declarations + +3.7.9 The Start-Symbol +---------------------- + +Bison assumes by default that the start symbol for the grammar is the +first nonterminal specified in the grammar specification section. The +programmer may override this restriction with the `%start' declaration +as follows: + + %start SYMBOL + + +File: bison.info, Node: Pure Decl, Next: Push Decl, Prev: Start Decl, Up: Declarations + +3.7.10 A Pure (Reentrant) Parser +-------------------------------- + +A "reentrant" program is one which does not alter in the course of +execution; in other words, it consists entirely of "pure" (read-only) +code. Reentrancy is important whenever asynchronous execution is +possible; for example, a nonreentrant program may not be safe to call +from a signal handler. In systems with multiple threads of control, a +nonreentrant program must be called only within interlocks. + + Normally, Bison generates a parser which is not reentrant. This is +suitable for most uses, and it permits compatibility with Yacc. (The +standard Yacc interfaces are inherently nonreentrant, because they use +statically allocated variables for communication with `yylex', +including `yylval' and `yylloc'.) + + Alternatively, you can generate a pure, reentrant parser. The Bison +declaration `%define api.pure' says that you want the parser to be +reentrant. It looks like this: + + %define api.pure + + The result is that the communication variables `yylval' and `yylloc' +become local variables in `yyparse', and a different calling convention +is used for the lexical analyzer function `yylex'. *Note Calling +Conventions for Pure Parsers: Pure Calling, for the details of this. +The variable `yynerrs' becomes local in `yyparse' in pull mode but it +becomes a member of yypstate in push mode. (*note The Error Reporting +Function `yyerror': Error Reporting.). The convention for calling +`yyparse' itself is unchanged. + + Whether the parser is pure has nothing to do with the grammar rules. +You can generate either a pure parser or a nonreentrant parser from any +valid grammar. + + +File: bison.info, Node: Push Decl, Next: Decl Summary, Prev: Pure Decl, Up: Declarations + +3.7.11 A Push Parser +-------------------- + +(The current push parsing interface is experimental and may evolve. +More user feedback will help to stabilize it.) + + A pull parser is called once and it takes control until all its input +is completely parsed. A push parser, on the other hand, is called each +time a new token is made available. + + A push parser is typically useful when the parser is part of a main +event loop in the client's application. This is typically a +requirement of a GUI, when the main event loop needs to be triggered +within a certain time period. + + Normally, Bison generates a pull parser. The following Bison +declaration says that you want the parser to be a push parser (*note +%define api.push_pull: Decl Summary.): + + %define api.push_pull "push" + + In almost all cases, you want to ensure that your push parser is also +a pure parser (*note A Pure (Reentrant) Parser: Pure Decl.). The only +time you should create an impure push parser is to have backwards +compatibility with the impure Yacc pull mode interface. Unless you know +what you are doing, your declarations should look like this: + + %define api.pure + %define api.push_pull "push" + + There is a major notable functional difference between the pure push +parser and the impure push parser. It is acceptable for a pure push +parser to have many parser instances, of the same type of parser, in +memory at the same time. An impure push parser should only use one +parser at a time. + + When a push parser is selected, Bison will generate some new symbols +in the generated parser. `yypstate' is a structure that the generated +parser uses to store the parser's state. `yypstate_new' is the +function that will create a new parser instance. `yypstate_delete' +will free the resources associated with the corresponding parser +instance. Finally, `yypush_parse' is the function that should be +called whenever a token is available to provide the parser. A trivial +example of using a pure push parser would look like this: + + int status; + yypstate *ps = yypstate_new (); + do { + status = yypush_parse (ps, yylex (), NULL); + } while (status == YYPUSH_MORE); + yypstate_delete (ps); + + If the user decided to use an impure push parser, a few things about +the generated parser will change. The `yychar' variable becomes a +global variable instead of a variable in the `yypush_parse' function. +For this reason, the signature of the `yypush_parse' function is +changed to remove the token as a parameter. A nonreentrant push parser +example would thus look like this: + + extern int yychar; + int status; + yypstate *ps = yypstate_new (); + do { + yychar = yylex (); + status = yypush_parse (ps); + } while (status == YYPUSH_MORE); + yypstate_delete (ps); + + That's it. Notice the next token is put into the global variable +`yychar' for use by the next invocation of the `yypush_parse' function. + + Bison also supports both the push parser interface along with the +pull parser interface in the same generated parser. In order to get +this functionality, you should replace the `%define api.push_pull +"push"' declaration with the `%define api.push_pull "both"' +declaration. Doing this will create all of the symbols mentioned +earlier along with the two extra symbols, `yyparse' and `yypull_parse'. +`yyparse' can be used exactly as it normally would be used. However, +the user should note that it is implemented in the generated parser by +calling `yypull_parse'. This makes the `yyparse' function that is +generated with the `%define api.push_pull "both"' declaration slower +than the normal `yyparse' function. If the user calls the +`yypull_parse' function it will parse the rest of the input stream. It +is possible to `yypush_parse' tokens to select a subgrammar and then +`yypull_parse' the rest of the input stream. If you would like to +switch back and forth between between parsing styles, you would have to +write your own `yypull_parse' function that knows when to quit looking +for input. An example of using the `yypull_parse' function would look +like this: + + yypstate *ps = yypstate_new (); + yypull_parse (ps); /* Will call the lexer */ + yypstate_delete (ps); + + Adding the `%define api.pure' declaration does exactly the same +thing to the generated parser with `%define api.push_pull "both"' as it +did for `%define api.push_pull "push"'. + + +File: bison.info, Node: Decl Summary, Prev: Push Decl, Up: Declarations + +3.7.12 Bison Declaration Summary +-------------------------------- + +Here is a summary of the declarations used to define a grammar: + + -- Directive: %union + Declare the collection of data types that semantic values may have + (*note The Collection of Value Types: Union Decl.). + + -- Directive: %token + Declare a terminal symbol (token type name) with no precedence or + associativity specified (*note Token Type Names: Token Decl.). + + -- Directive: %right + Declare a terminal symbol (token type name) that is + right-associative (*note Operator Precedence: Precedence Decl.). + + -- Directive: %left + Declare a terminal symbol (token type name) that is + left-associative (*note Operator Precedence: Precedence Decl.). + + -- Directive: %nonassoc + Declare a terminal symbol (token type name) that is nonassociative + (*note Operator Precedence: Precedence Decl.).

It inserts + CODE verbatim at a language-dependent default location in the + output(1). + + For C/C++, the default location is the parser source code file + after the usual contents of the parser header file. Thus, `%code' + replaces the traditional Yacc prologue, `%{CODE%}', for most + purposes. For a detailed discussion, see *note Prologue + Alternatives::. + + For Java, the default location is inside the parser class. + + (Like all the Yacc prologue alternatives, this directive is + experimental. More user feedback will help to determine whether + it should become a permanent feature.) + + -- Directive: %code QUALIFIER {CODE} + This is the qualified form of the `%code' directive. If you need + to specify location-sensitive verbatim CODE that does not belong + at the default location selected by the unqualified `%code' form, + use this form instead. + + QUALIFIER identifies the purpose of CODE and thus the location(s) + where Bison should generate it. Not all values of QUALIFIER are + available for all target languages: + + * requires + + * Language(s): C, C++ + + * Purpose: This is the best place to write dependency code + required for `YYSTYPE' and `YYLTYPE'. In other words, + it's the best place to define types referenced in + `%union' directives, and it's the best place to override + Bison's default `YYSTYPE' and `YYLTYPE' definitions. + + * Location(s): The parser header file and the parser + source code file before the Bison-generated `YYSTYPE' + and `YYLTYPE' definitions. + + * provides + + * Language(s): C, C++ + + * Purpose: This is the best place to write additional + definitions and declarations that should be provided to + other modules. + + * Location(s): The parser header file and the parser + source code file after the Bison-generated `YYSTYPE', + `YYLTYPE', and token definitions. + + * top + + * Language(s): C, C++ + + * Purpose: The unqualified `%code' or `%code requires' + should usually be more appropriate than `%code top'. + However, occasionally it is necessary to insert code + much nearer the top of the parser source code file. For + example: + + %code top { + #define _GNU_SOURCE + #include + } + + * Location(s): Near the top of the parser source code file. + + * imports + + * Language(s): Java + + * Purpose: This is the best place to write Java import + directives. + + * Location(s): The parser Java file after any Java package + directive and before any class definitions. + + (Like all the Yacc prologue alternatives, this directive is + experimental. More user feedback will help to determine whether + it should become a permanent feature.) + + For a detailed discussion of how to use `%code' in place of the + traditional Yacc prologue for C/C++, see *note Prologue + Alternatives::. + + -- Directive: %debug + In the parser file, define the macro `YYDEBUG' to 1 if it is not + already defined, so that the debugging facilities are compiled. + *Note Tracing Your Parser: Tracing. + + -- Directive: %define VARIABLE + -- Directive: %define VARIABLE "VALUE" + Define a variable to adjust Bison's behavior. The possible + choices for VARIABLE, as well as their meanings, depend on the + selected target language and/or the parser skeleton (*note + %language: Decl Summary, *note %skeleton: Decl Summary.). + + Bison will warn if a VARIABLE is defined multiple times. + + Omitting `"VALUE"' is always equivalent to specifying it as `""'. + + Some VARIABLEs may be used as Booleans.

This is equivalent to + `"true"'. + + 3. `"VALUE"' is `"false"'. + + 4. VARIABLE is never defined. In this case, Bison selects a + default value, which may depend on the selected target + language and/or parser skeleton. + + Some of the accepted VARIABLEs are: + + * api.pure + + * Language(s): C + + * Purpose: Request a pure (reentrant) parser program. + *Note A Pure (Reentrant) Parser: Pure Decl. + + * Accepted Values: Boolean + + * Default Value: `"false"' + + * api.push_pull + + * Language(s): C (LALR(1) only) + + * Purpose: Requests a pull parser, a push parser, or both. + *Note A Push Parser: Push Decl.

Bison considers + a state to be unreachable if there exists no sequence of + transitions from the start state to that state. A state + can become unreachable during conflict resolution if + Bison disables a shift action leading to it from a + predecessor state. Keeping unreachable states is + sometimes useful for analysis purposes, but they are + useless in the generated parser. + + * Accepted Values: Boolean + + * Default Value: `"false"' + + * Caveats: + + * Unreachable states may contain conflicts and may + use rules not used in any other state. Thus, + keeping unreachable states may induce warnings that + are irrelevant to your parser's behavior, and it + may eliminate warnings that are relevant. Of + course, the change in warnings may actually be + relevant to a parser table analysis that wants to + keep unreachable states, so this behavior will + likely remain in future Bison releases. + + * While Bison is able to remove unreachable states, + it is not guaranteed to remove other kinds of + useless states. Specifically, when Bison disables + reduce actions during conflict resolution, some + goto actions may become useless, and thus some + additional states may become useless. If Bison + were to compute which goto actions were useless and + then disable those actions, it could identify such + states as unreachable and then remove those states. + However, Bison does not compute which goto actions + are useless. + + * namespace + + * Languages(s): C++ + + * Purpose: Specifies the namespace for the parser class. + For example, if you specify: + + %define namespace "foo::bar" + + Bison uses `foo::bar' verbatim in references such as: + + foo::bar::parser::semantic_type + + However, to open a namespace, Bison removes any leading + `::' and then splits on any remaining occurrences: + + namespace foo { namespace bar { + class position; + class location; + } } + + * Accepted Values: Any absolute or relative C++ namespace + reference without a trailing `"::"'. For example, + `"foo"' or `"::foo::bar"'. + + * Default Value: The value specified by `%name-prefix', + which defaults to `yy'. This usage of `%name-prefix' is + for backward compatibility and can be confusing since + `%name-prefix' also specifies the textual prefix for the + lexical analyzer function. Thus, if you specify + `%name-prefix', it is best to also specify `%define + namespace' so that `%name-prefix' _only_ affects the + lexical analyzer function. For example, if you specify: + + %define namespace "foo" + %name-prefix "bar::" + + The parser namespace is `foo' and `yylex' is referenced + as `bar::lex'. + + + -- Directive: %defines + Write a header file containing macro definitions for the token type + names defined in the grammar as well as a few other declarations. + If the parser output file is named `NAME.c' then this file is + named `NAME.h'. + + For C parsers, the output header declares `YYSTYPE' unless + `YYSTYPE' is already defined as a macro or you have used a + `' tag without using `%union'. Therefore, if you are using + a `%union' (*note More Than One Value Type: Multiple Types.) with + components that require other definitions, or if you have defined + a `YYSTYPE' macro or type definition (*note Data Types of Semantic + Values: Value Type.), you need to arrange for these definitions to + be propagated to all modules, e.g., by putting them in a + prerequisite header that is included both by your parser and by + any other module that needs `YYSTYPE'. + + Unless your parser is pure, the output header declares `yylval' as + an external variable. *Note A Pure (Reentrant) Parser: Pure Decl. + + If you have also used locations, the output header declares + `YYLTYPE' and `yylloc' using a protocol similar to that of the + `YYSTYPE' macro and `yylval'. *Note Tracking Locations: Locations. + + This output file is normally essential if you wish to put the + definition of `yylex' in a separate source file, because `yylex' + typically needs to be able to refer to the above-mentioned + declarations and to the token type codes. *Note Semantic Values + of Tokens: Token Values. + + If you have declared `%code requires' or `%code provides', the + output header also contains their code. *Note %code: Decl Summary. + + -- Directive: %defines DEFINES-FILE + Same as above, but save in the file DEFINES-FILE. + + -- Directive: %destructor + Specify how the parser should reclaim the memory associated to + discarded symbols. *Note Freeing Discarded Symbols: Destructor + Decl. + + -- Directive: %file-prefix "PREFIX" + Specify a prefix to use for all Bison output file names.

But what if you want to parse more than +one language with the same program? Then you need to avoid a name +conflict between different definitions of `yyparse', `yylval', and so +on. + + The easy way to do this is to use the option `-p PREFIX' (*note +Invoking Bison: Invocation.). This renames the interface functions and +variables of the Bison parser to start with PREFIX instead of `yy'. +You can use this to give each parser distinct names that do not +conflict. + + The precise list of symbols renamed is `yyparse', `yylex', +`yyerror', `yynerrs', `yylval', `yylloc', `yychar' and `yydebug'. If +you use a push parser, `yypush_parse', `yypull_parse', `yypstate', +`yypstate_new' and `yypstate_delete' will also be renamed. For +example, if you use `-p c', the names become `cparse', `clex', and so +on. + + *All the other variables and macros associated with Bison are not +renamed.* These others are not global; there is no conflict if the same +name is used in different parsers. For example, `YYSTYPE' is not +renamed, but defining this in different ways in different parsers causes +no trouble (*note Data Types of Semantic Values: Value Type.). + + The `-p' option works by adding macro definitions to the beginning +of the parser source file, defining `yyparse' as `PREFIXparse', and so +on.

Bison does not create +this function automatically; you must write it so that `yyparse' can +call it. The function is sometimes referred to as a lexical scanner. + + In simple programs, `yylex' is often defined at the end of the Bison +grammar file. If `yylex' is defined in a separate source file, you +need to arrange for the token-type macro definitions to be available +there. To do this, use the `-d' option when you run Bison, so that it +will write these macro definitions into a separate header file +`NAME.tab.h' which you can include in the other source files that need +it. *Note Invoking Bison: Invocation. + +* Menu: + +* Calling Convention:: How `yyparse' calls `yylex'. +* Token Values:: How `yylex' must return the semantic value + of the token it has read. +* Token Locations:: How `yylex' must return the text location + (line number, etc.) of the token, if the + actions want that. +* Pure Calling:: How the calling convention differs in a pure parser + (*note A Pure (Reentrant) Parser: Pure Decl.). + + +File: bison.info, Node: Calling Convention, Next: Token Values, Up: Lexical + +4.6.1 Calling Convention for `yylex' +------------------------------------ + +The value that `yylex' returns must be the positive numeric code for +the type of token it has just found; a zero or negative value signifies +end-of-input. + + When a token is referred to in the grammar rules by a name, that name +in the parser file becomes a C macro whose definition is the proper +numeric code for that token type. So `yylex' can use the name to +indicate that type. *Note Symbols::. + + When a token is referred to in the grammar rules by a character +literal, the numeric code for that character is also the code for the +token type. So `yylex' can simply return that character code, possibly +converted to `unsigned char' to avoid sign-extension. The null +character must not be used this way, because its code is zero and that +signifies end-of-input. + + Here is an example showing these things: + + int + yylex (void) + { + ... + if (c == EOF) /* Detect end-of-input. */ + return 0; + ... + if (c == '+' || c == '-') + return c; /* Assume token type for `+' is '+'. */ + ... + return INT; /* Return the type of the token. */ + ... + } + +This interface has been designed so that the output from the `lex' +utility can be used without change as the definition of `yylex'. + + If the grammar uses literal string tokens, there are two ways that +`yylex' can determine the token type codes for them: + + * If the grammar defines symbolic token names as aliases for the + literal string tokens, `yylex' can use these symbolic names like + all others. In this case, the use of the literal string tokens in + the grammar file has no effect on `yylex'. + + * `yylex' can find the multicharacter token in the `yytname' table. + The index of the token in the table is the token type's code. The + name of a multicharacter token is recorded in `yytname' with a + double-quote, the token's characters, and another double-quote. + The token's characters are escaped as necessary to be suitable as + input to Bison. + + Here's code for looking up a multicharacter token in `yytname', + assuming that the characters of the token are stored in + `token_buffer', and assuming that the token does not contain any + characters like `"' that require escaping. + + for (i = 0; i < YYNTOKENS; i++) + { + if (yytname[i] != 0 + && yytname[i][0] == '"' + && ! strncmp (yytname[i] + 1, token_buffer, + strlen (token_buffer)) + && yytname[i][strlen (token_buffer) + 1] == '"' + && yytname[i][strlen (token_buffer) + 2] == 0) + break; + } + + The `yytname' table is generated only if you use the + `%token-table' declaration. *Note Decl Summary::. + + +File: bison.info, Node: Token Values, Next: Token Locations, Prev: Calling Convention, Up: Lexical + +4.6.2 Semantic Values of Tokens +------------------------------- + +In an ordinary (nonreentrant) parser, the semantic value of the token +must be stored into the global variable `yylval'. When you are using +just one data type for semantic values, `yylval' has that type. Thus, +if the type is `int' (the default), you might write this in `yylex': + + ... + yylval = value; /* Put value onto Bison stack. */ + return INT; /* Return the type of the token. */ + ... + + When you are using multiple data types, `yylval''s type is a union +made from the `%union' declaration (*note The Collection of Value +Types: Union Decl.). So when you store a token's value, you must use +the proper member of the union. If the `%union' declaration looks like +this: + + %union { + int intval; + double val; + symrec *tptr; + } + +then the code in `yylex' might look like this: + + ... + yylval.intval = value; /* Put value onto Bison stack. */ + return INT; /* Return the type of the token. */ + ... + + +File: bison.info, Node: Token Locations, Next: Pure Calling, Prev: Token Values, Up: Lexical + +4.6.3 Textual Locations of Tokens +--------------------------------- + +If you are using the `@N'-feature (*note Tracking Locations: +Locations.) in actions to keep track of the textual locations of tokens +and groupings, then you must provide this information in `yylex'. The +function `yyparse' expects to find the textual location of a token just +parsed in the global variable `yylloc'. So `yylex' must store the +proper data in that variable. + + By default, the value of `yylloc' is a structure and you need only +initialize the members that are going to be used by the actions. The +four members are called `first_line', `first_column', `last_line' and +`last_column'. Note that the use of this feature makes the parser +noticeably slower. + + The data type of `yylloc' has the name `YYLTYPE'. + + +File: bison.info, Node: Pure Calling, Prev: Token Locations, Up: Lexical + +4.6.4 Calling Conventions for Pure Parsers +------------------------------------------ + +When you use the Bison declaration `%define api.pure' to request a +pure, reentrant parser, the global communication variables `yylval' and +`yylloc' cannot be used. (*Note A Pure (Reentrant) Parser: Pure Decl.) +In such parsers the two global variables are replaced by pointers +passed as arguments to `yylex'. You must declare them as shown here, +and pass the information back by storing it through those pointers. + + int + yylex (YYSTYPE *lvalp, YYLTYPE *llocp) + { + ... + *lvalp = value; /* Put value onto Bison stack. */ + return INT; /* Return the type of the token. */ + ... + } + + If the grammar file does not use the `@' constructs to refer to +textual locations, then the type `YYLTYPE' will not be defined. In +this case, omit the second argument; `yylex' will be called with only +one argument. + + If you wish to pass the additional parameter data to `yylex', use +`%lex-param' just like `%parse-param' (*note Parser Function::). + + -- Directive: lex-param {ARGUMENT-DECLARATION} + Declare that the braced-code ARGUMENT-DECLARATION is an additional + `yylex' argument declaration. + + For instance: + + %parse-param {int *nastiness} + %lex-param {int *nastiness} + %parse-param {int *randomness} + +results in the following signature: + + int yylex (int *nastiness); + int yyparse (int *nastiness, int *randomness); + + If `%define api.pure' is added: + + int yylex (YYSTYPE *lvalp, int *nastiness); + int yyparse (int *nastiness, int *randomness); + +and finally, if both `%define api.pure' and `%locations' are used: + + int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness); + int yyparse (int *nastiness, int *randomness); + + +File: bison.info, Node: Error Reporting, Next: Action Features, Prev: Lexical, Up: Interface + +4.7 The Error Reporting Function `yyerror' +========================================== + +The Bison parser detects a "syntax error" or "parse error" whenever it +reads a token which cannot satisfy any syntax rule. An action in the +grammar can also explicitly proclaim an error, using the macro +`YYERROR' (*note Special Features for Use in Actions: Action Features.). + + The Bison parser expects to report the error by calling an error +reporting function named `yyerror', which you must supply. It is +called by `yyparse' whenever a syntax error is found, and it receives +one argument. For a syntax error, the string is normally +`"syntax error"'. + + If you invoke the directive `%error-verbose' in the Bison +declarations section (*note The Bison Declarations Section: Bison +Declarations.), then Bison provides a more verbose and specific error +message string instead of just plain `"syntax error"'. + + The parser can detect one other kind of error: memory exhaustion. +This can happen when the input contains constructions that are very +deeply nested. It isn't likely you will encounter this, since the Bison +parser normally extends its stack automatically up to a very large +limit. But if memory is exhausted, `yyparse' calls `yyerror' in the +usual fashion, except that the argument string is `"memory exhausted"'. + + In some cases diagnostics like `"syntax error"' are translated +automatically from English to some other language before they are +passed to `yyerror'. *Note Internationalization::. + + The following definition suffices in simple programs: + + void + yyerror (char const *s) + { + fprintf (stderr, "%s\n", s); + } + + After `yyerror' returns to `yyparse', the latter will attempt error +recovery if you have written suitable error recovery grammar rules +(*note Error Recovery::). If recovery is impossible, `yyparse' will +immediately return 1. + + Obviously, in location tracking pure parsers, `yyerror' should have +an access to the current location. This is indeed the case for the GLR +parsers, but not for the Yacc parser, for historical reasons. I.e., if +`%locations %define api.pure' is passed then the prototypes for +`yyerror' are: + + void yyerror (char const *msg); /* Yacc parsers. */ + void yyerror (YYLTYPE *locp, char const *msg); /* GLR parsers. */ + + If `%parse-param {int *nastiness}' is used, then: + + void yyerror (int *nastiness, char const *msg); /* Yacc parsers. */ + void yyerror (int *nastiness, char const *msg); /* GLR parsers. */ + + Finally, GLR and Yacc parsers share the same `yyerror' calling +convention for absolutely pure parsers, i.e., when the calling +convention of `yylex' _and_ the calling convention of `%define +api.pure' are pure. I.e.: + + /* Location tracking. */ + %locations + /* Pure yylex. */ + %define api.pure + %lex-param {int *nastiness} + /* Pure yyparse. */ + %parse-param {int *nastiness} + %parse-param {int *randomness} + +results in the following signatures for all the parser kinds: + + int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness); + int yyparse (int *nastiness, int *randomness); + void yyerror (YYLTYPE *locp, + int *nastiness, int *randomness, + char const *msg); + +The prototypes are only indications of how the code produced by Bison +uses `yyerror'. Bison-generated code always ignores the returned +value, so `yyerror' can return any type, including `void'. Also, +`yyerror' can be a variadic function; that is why the message is always +passed last. + + Traditionally `yyerror' returns an `int' that is always ignored, but +this is purely for historical reasons, and `void' is preferable since +it more accurately describes the return type for `yyerror'. + + The variable `yynerrs' contains the number of syntax errors reported +so far. Normally this variable is global; but if you request a pure +parser (*note A Pure (Reentrant) Parser: Pure Decl.) then it is a +local variable which only the actions can access. + + +File: bison.info, Node: Action Features, Next: Internationalization, Prev: Error Reporting, Up: Interface + +4.8 Special Features for Use in Actions +======================================= + +Here is a table of Bison constructs, variables and macros that are +useful in actions. + + -- Variable: $$ + Acts like a variable that contains the semantic value for the + grouping made by the current rule. *Note Actions::. + + -- Variable: $N + Acts like a variable that contains the semantic value for the Nth + component of the current rule. *Note Actions::. + + -- Variable: $$ + Like `$$' but specifies alternative TYPEALT in the union specified + by the `%union' declaration. *Note Data Types of Values in + Actions: Action Types. + + -- Variable: $N + Like `$N' but specifies alternative TYPEALT in the union specified + by the `%union' declaration. *Note Data Types of Values in + Actions: Action Types. + + -- Macro: YYABORT; + Return immediately from `yyparse', indicating failure. *Note The + Parser Function `yyparse': Parser Function. + + -- Macro: YYACCEPT; + Return immediately from `yyparse', indicating success. *Note The + Parser Function `yyparse': Parser Function. + + -- Macro: YYBACKUP (TOKEN, VALUE); + Unshift a token.

By default, they appear in English. However, Bison +also supports outputting diagnostics in the user's native language. To +make this work, the user should set the usual environment variables. +*Note The User's View: (gettext)Users. For example, the shell command +`export LC_ALL=fr_CA.UTF-8' might set the user's locale to French +Canadian using the UTF-8 encoding. The exact set of available locales +depends on the user's installation. + + The maintainer of a package that uses a Bison-generated parser +enables the internationalization of the parser's output through the +following steps. Here we assume a package that uses GNU Autoconf and +GNU Automake. + + 1. Into the directory containing the GNU Autoconf macros used by the + package--often called `m4'--copy the `bison-i18n.m4' file + installed by Bison under `share/aclocal/bison-i18n.m4' in Bison's + installation directory. For example: + + cp /usr/local/share/aclocal/bison-i18n.m4 m4/bison-i18n.m4 + + 2. In the top-level `configure.ac', after the `AM_GNU_GETTEXT' + invocation, add an invocation of `BISON_I18N'. This macro is + defined in the file `bison-i18n.m4' that you copied earlier. It + causes `configure' to find the value of the `BISON_LOCALEDIR' + variable, and it defines the source-language symbol `YYENABLE_NLS' + to enable translations in the Bison-generated parser. + + 3. In the `main' function of your program, designate the directory + containing Bison's runtime message catalog, through a call to + `bindtextdomain' with domain name `bison-runtime'. For example: + + bindtextdomain ("bison-runtime", BISON_LOCALEDIR); + + Typically this appears after any other call `bindtextdomain + (PACKAGE, LOCALEDIR)' that your package already has. Here we rely + on `BISON_LOCALEDIR' to be defined as a string through the + `Makefile'. + + 4. In the `Makefile.am' that controls the compilation of the `main' + function, make `BISON_LOCALEDIR' available as a C preprocessor + macro, either in `DEFS' or in `AM_CPPFLAGS'. For example: + + DEFS = @DEFS@ -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"' + + or: + + AM_CPPFLAGS = -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"' + + 5. Finally, invoke the command `autoreconf' to generate the build + infrastructure. + + +File: bison.info, Node: Algorithm, Next: Error Recovery, Prev: Interface, Up: Top + +5 The Bison Parser Algorithm +**************************** + +As Bison reads tokens, it pushes them onto a stack along with their +semantic values. The stack is called the "parser stack". Pushing a +token is traditionally called "shifting". + + For example, suppose the infix calculator has read `1 + 5 *', with a +`3' to come. The stack will have four elements, one for each token +that was shifted. + + But the stack does not always have an element for each token read. +When the last N tokens and groupings shifted match the components of a +grammar rule, they can be combined according to that rule. This is +called "reduction". Those tokens and groupings are replaced on the +stack by a single grouping whose symbol is the result (left hand side) +of that rule. Running the rule's action is part of the process of +reduction, because this is what computes the semantic value of the +resulting grouping. + + For example, if the infix calculator's parser stack contains this: + + 1 + 5 * 3 + +and the next input token is a newline character, then the last three +elements can be reduced to 15 via the rule: + + expr: expr '*' expr; + +Then the stack contains just these three elements: + + 1 + 15 + +At this point, another reduction can be made, resulting in the single +value 16. Then the newline token can be shifted. + + The parser tries, by shifts and reductions, to reduce the entire +input down to a single grouping whose symbol is the grammar's +start-symbol (*note Languages and Context-Free Grammars: Language and +Grammar.). + + This kind of parser is known in the literature as a bottom-up parser. + +* Menu: + +* Lookahead:: Parser looks one token ahead when deciding what to do. +* Shift/Reduce:: Conflicts: when either shifting or reduction is valid. +* Precedence:: Operator precedence works by resolving conflicts. +* Contextual Precedence:: When an operator's precedence depends on context. +* Parser States:: The parser is a finite-state-machine with stack. +* Reduce/Reduce:: When two rules are applicable in the same situation. +* Mystery Conflicts:: Reduce/reduce conflicts that look unjustified. +* Generalized LR Parsing:: Parsing arbitrary context-free grammars. +* Memory Management:: What happens when memory is exhausted. How to avoid it. + + +File: bison.info, Node: Lookahead, Next: Shift/Reduce, Up: Algorithm + +5.1 Lookahead Tokens +==================== + +The Bison parser does _not_ always reduce immediately as soon as the +last N tokens and groupings match a rule. This is because such a +simple strategy is inadequate to handle most languages. Instead, when a +reduction is possible, the parser sometimes "looks ahead" at the next +token in order to decide what to do. + + When a token is read, it is not immediately shifted; first it +becomes the "lookahead token", which is not on the stack. Now the +parser can perform one or more reductions of tokens and groupings on +the stack, while the lookahead token remains off to the side. When no +more reductions should take place, the lookahead token is shifted onto +the stack. This does not mean that all possible reductions have been +done; depending on the token type of the lookahead token, some rules +may choose to delay their application. + + Here is a simple case where lookahead is needed. These three rules +define expressions which contain binary addition operators and postfix +unary factorial operators (`!'), and allow parentheses for grouping. + + expr: term '+' expr + | term + ; + + term: '(' expr ')' + | term '!' + | NUMBER + ; + + Suppose that the tokens `1 + 2' have been read and shifted; what +should be done? If the following token is `)', then the first three +tokens must be reduced to form an `expr'. This is the only valid +course, because shifting the `)' would produce a sequence of symbols +`term ')'', and no rule allows this. + + If the following token is `!', then it must be shifted immediately so +that `2 !' can be reduced to make a `term'. If instead the parser were +to reduce before shifting, `1 + 2' would become an `expr'. It would +then be impossible to shift the `!' because doing so would produce on +the stack the sequence of symbols `expr '!''. No rule allows that +sequence. + + The lookahead token is stored in the variable `yychar'. Its +semantic value and location, if any, are stored in the variables +`yylval' and `yylloc'. *Note Special Features for Use in Actions: +Action Features. + + +File: bison.info, Node: Shift/Reduce, Next: Precedence, Prev: Lookahead, Up: Algorithm + +5.2 Shift/Reduce Conflicts +========================== + +Suppose we are parsing a language which has if-then and if-then-else +statements, with a pair of rules like this: + + if_stmt: + IF expr THEN stmt + | IF expr THEN stmt ELSE stmt + ; + +Here we assume that `IF', `THEN' and `ELSE' are terminal symbols for +specific keyword tokens. + + When the `ELSE' token is read and becomes the lookahead token, the +contents of the stack (assuming the input is valid) are just right for +reduction by the first rule. But it is also legitimate to shift the +`ELSE', because that would lead to eventual reduction by the second +rule. + + This situation, where either a shift or a reduction would be valid, +is called a "shift/reduce conflict". Bison is designed to resolve +these conflicts by choosing to shift, unless otherwise directed by +operator precedence declarations. To see the reason for this, let's +contrast it with the other alternative. + + Since the parser prefers to shift the `ELSE', the result is to attach +the else-clause to the innermost if-statement, making these two inputs +equivalent: + + if x then if y then win (); else lose; + + if x then do; if y then win (); else lose; end; + + But if the parser chose to reduce when possible rather than shift, +the result would be to attach the else-clause to the outermost +if-statement, making these two inputs equivalent: + + if x then if y then win (); else lose; + + if x then do; if y then win (); end; else lose; + + The conflict exists because the grammar as written is ambiguous: +either parsing of the simple nested if-statement is legitimate. The +established convention is that these ambiguities are resolved by +attaching the else-clause to the innermost if-statement; this is what +Bison accomplishes by choosing to shift rather than reduce. (It would +ideally be cleaner to write an unambiguous grammar, but that is very +hard to do in this case.) This particular ambiguity was first +encountered in the specifications of Algol 60 and is called the +"dangling `else'" ambiguity. + + To avoid warnings from Bison about predictable, legitimate +shift/reduce conflicts, use the `%expect N' declaration. There will be +no warning as long as the number of shift/reduce conflicts is exactly N. +*Note Suppressing Conflict Warnings: Expect Decl. + + The definition of `if_stmt' above is solely to blame for the +conflict, but the conflict does not actually appear without additional +rules.

It depends on +the next token. Of course, if the next token is `)', we must reduce; +shifting is invalid because no single rule can reduce the token +sequence `- 2 )' or anything starting with that. But if the next token +is `*' or `<', we have a choice: either shifting or reduction would +allow the parse to complete, but with different results. + + To decide which one Bison should do, we must consider the results. +If the next operator token OP is shifted, then it must be reduced first +in order to permit another opportunity to reduce the difference. The +result is (in effect) `1 - (2 OP 3)'. On the other hand, if the +subtraction is reduced before shifting OP, the result is +`(1 - 2) OP 3'. Clearly, then, the choice of shift or reduce should +depend on the relative precedence of the operators `-' and OP: `*' +should be shifted first, but not `<'. + + What about input such as `1 - 2 - 5'; should this be `(1 - 2) - 5' +or should it be `1 - (2 - 5)'? For most operators we prefer the +former, which is called "left association". The latter alternative, +"right association", is desirable for assignment operators. The choice +of left or right association is a matter of whether the parser chooses +to shift or reduce when the stack contains `1 - 2' and the lookahead +token is `-': shifting makes right-associativity. + + +File: bison.info, Node: Using Precedence, Next: Precedence Examples, Prev: Why Precedence, Up: Precedence + +5.3.2 Specifying Operator Precedence +------------------------------------ + +Bison allows you to specify these choices with the operator precedence +declarations `%left' and `%right'. Each such declaration contains a +list of tokens, which are operators whose precedence and associativity +is being declared. The `%left' declaration makes all those operators +left-associative and the `%right' declaration makes them +right-associative. A third alternative is `%nonassoc', which declares +that it is a syntax error to find the same operator twice "in a row". + + The relative precedence of different operators is controlled by the +order in which they are declared. The first `%left' or `%right' +declaration in the file declares the operators whose precedence is +lowest, the next such declaration declares the operators whose +precedence is a little higher, and so on. + + +File: bison.info, Node: Precedence Examples, Next: How Precedence, Prev: Using Precedence, Up: Precedence + +5.3.3 Precedence Examples +------------------------- + +In our example, we would want the following declarations: + + %left '<' + %left '-' + %left '*' + + In a more complete example, which supports other operators as well, +we would declare them in groups of equal precedence. For example, +`'+'' is declared with `'-'': + + %left '<' '>' '=' NE LE GE + %left '+' '-' + %left '*' '/' + +(Here `NE' and so on stand for the operators for "not equal" and so on. +We assume that these tokens are more than one character long and +therefore are represented by names, not character literals.) + + +File: bison.info, Node: How Precedence, Prev: Precedence Examples, Up: Precedence + +5.3.4 How Precedence Works +-------------------------- + +The first effect of the precedence declarations is to assign precedence +levels to the terminal symbols declared. The second effect is to assign +precedence levels to certain rules: each rule gets its precedence from +the last terminal symbol mentioned in the components. (You can also +specify explicitly the precedence of a rule. *Note Context-Dependent +Precedence: Contextual Precedence.) + + Finally, the resolution of conflicts works by comparing the +precedence of the rule being considered with that of the lookahead +token. If the token's precedence is higher, the choice is to shift. +If the rule's precedence is higher, the choice is to reduce. If they +have equal precedence, the choice is made based on the associativity of +that precedence level. The verbose output file made by `-v' (*note +Invoking Bison: Invocation.) says how each conflict was resolved. + + Not all rules and not all tokens have precedence. If either the +rule or the lookahead token has no precedence, then the default is to +shift. + + +File: bison.info, Node: Contextual Precedence, Next: Parser States, Prev: Precedence, Up: Algorithm + +5.4 Context-Dependent Precedence +================================ + +Often the precedence of an operator depends on the context. This sounds +outlandish at first, but it is really very common. For example, a minus +sign typically has a very high precedence as a unary operator, and a +somewhat lower precedence (lower than multiplication) as a binary +operator. + + The Bison precedence declarations, `%left', `%right' and +`%nonassoc', can only be used once for a given token; so a token has +only one precedence declared in this way. For context-dependent +precedence, you need to use an additional mechanism: the `%prec' +modifier for rules. + + The `%prec' modifier declares the precedence of a particular rule by +specifying a terminal symbol whose precedence should be used for that +rule. It's not necessary for that symbol to appear otherwise in the +rule. The modifier's syntax is: + + %prec TERMINAL-SYMBOL + +and it is written after the components of the rule. Its effect is to +assign the rule the precedence of TERMINAL-SYMBOL, overriding the +precedence that would be deduced for it in the ordinary way. The +altered rule precedence then affects how conflicts involving that rule +are resolved (*note Operator Precedence: Precedence.). + + Here is how `%prec' solves the problem of unary minus. First, +declare a precedence for a fictitious terminal symbol named `UMINUS'. +There are no tokens of this type, but the symbol serves to stand for its +precedence: + + ... + %left '+' '-' + %left '*' + %left UMINUS + + Now the precedence of `UMINUS' can be used in specific rules: + + exp: ... + | exp '-' exp + ... + | '-' exp %prec UMINUS + + +File: bison.info, Node: Parser States, Next: Reduce/Reduce, Prev: Contextual Precedence, Up: Algorithm + +5.5 Parser States +================= + +The function `yyparse' is implemented using a finite-state machine. +The values pushed on the parser stack are not simply token type codes; +they represent the entire sequence of terminal and nonterminal symbols +at or near the top of the stack. The current state collects all the +information about previous input which is relevant to deciding what to +do next. + + Each time a lookahead token is read, the current parser state +together with the type of lookahead token are looked up in a table. +This table entry can say, "Shift the lookahead token." In this case, +it also specifies the new parser state, which is pushed onto the top of +the parser stack. Or it can say, "Reduce using rule number N." This +means that a certain number of tokens or groupings are taken off the +top of the stack, and replaced by one grouping. In other words, that +number of states are popped from the stack, and one new state is pushed. + + There is one other alternative: the table can say that the lookahead +token is erroneous in the current state. This causes error processing +to begin (*note Error Recovery::). + + +File: bison.info, Node: Reduce/Reduce, Next: Mystery Conflicts, Prev: Parser States, Up: Algorithm + +5.6 Reduce/Reduce Conflicts +=========================== + +A reduce/reduce conflict occurs if there are two or more rules that +apply to the same sequence of input. This usually indicates a serious +error in the grammar. + + For example, here is an erroneous attempt to define a sequence of +zero or more `word' groupings. + + sequence: /* empty */ + { printf ("empty sequence\n"); } + | maybeword + | sequence word + { printf ("added word %s\n", $2); } + ; + + maybeword: /* empty */ + { printf ("empty maybeword\n"); } + | word + { printf ("single word %s\n", $1); } + ; + +The error is an ambiguity: there is more than one way to parse a single +`word' into a `sequence'. It could be reduced to a `maybeword' and +then into a `sequence' via the second rule. Alternatively, +nothing-at-all could be reduced into a `sequence' via the first rule, +and this could be combined with the `word' using the third rule for +`sequence'. + + There is also more than one way to reduce nothing-at-all into a +`sequence'. This can be done directly via the first rule, or +indirectly via `maybeword' and then the second rule. + + You might think that this is a distinction without a difference, +because it does not change whether any particular input is valid or +not. But it does affect which actions are run. One parsing order runs +the second rule's action; the other runs the first rule's action and +the third rule's action. In this example, the output of the program +changes. + + Bison resolves a reduce/reduce conflict by choosing to use the rule +that appears first in the grammar, but it is very risky to rely on +this. Every reduce/reduce conflict must be studied and usually +eliminated. Here is the proper way to define `sequence': + + sequence: /* empty */ + { printf ("empty sequence\n"); } + | sequence word + { printf ("added word %s\n", $2); } + ; + + Here is another common error that yields a reduce/reduce conflict: + + sequence: /* empty */ + | sequence words + | sequence redirects + ; + + words: /* empty */ + | words word + ; + + redirects:/* empty */ + | redirects redirect + ; + +The intention here is to define a sequence which can contain either +`word' or `redirect' groupings. The individual definitions of +`sequence', `words' and `redirects' are error-free, but the three +together make a subtle ambiguity: even an empty input can be parsed in +infinitely many ways! + + Consider: nothing-at-all could be a `words'. Or it could be two +`words' in a row, or three, or any number. It could equally well be a +`redirects', or two, or any number. Or it could be a `words' followed +by three `redirects' and another `words'. And so on. + + Here are two ways to correct these rules. First, to make it a +single level of sequence: + + sequence: /* empty */ + | sequence word + | sequence redirect + ; + + Second, to prevent either a `words' or a `redirects' from being +empty: + + sequence: /* empty */ + | sequence words + | sequence redirects + ; + + words: word + | words word + ; + + redirects:redirect + | redirects redirect + ; + + +File: bison.info, Node: Mystery Conflicts, Next: Generalized LR Parsing, Prev: Reduce/Reduce, Up: Algorithm + +5.7 Mysterious Reduce/Reduce Conflicts +====================================== + +Sometimes reduce/reduce conflicts can occur that don't look warranted. +Here is an example: + + %token ID + + %% + def: param_spec return_spec ',' + ; + param_spec: + type + | name_list ':' type + ; + return_spec: + type + | name ':' type + ; + type: ID + ; + name: ID + ; + name_list: + name + | name ',' name_list + ; + + It would seem that this grammar can be parsed with only a single +token of lookahead: when a `param_spec' is being read, an `ID' is a +`name' if a comma or colon follows, or a `type' if another `ID' +follows. In other words, this grammar is LR(1). + + However, Bison, like most parser generators, cannot actually handle +all LR(1) grammars. In this grammar, two contexts, that after an `ID' +at the beginning of a `param_spec' and likewise at the beginning of a +`return_spec', are similar enough that Bison assumes they are the same. +They appear similar because the same set of rules would be active--the +rule for reducing to a `name' and that for reducing to a `type'. Bison +is unable to determine at that stage of processing that the rules would +require different lookahead tokens in the two contexts, so it makes a +single parser state for them both. Combining the two contexts causes a +conflict later. In parser terminology, this occurrence means that the +grammar is not LALR(1). + + In general, it is better to fix deficiencies than to document them. +But this particular deficiency is intrinsically hard to fix; parser +generators that can handle LR(1) grammars are hard to write and tend to +produce parsers that are very large. In practice, Bison is more useful +as it is now. + + When the problem arises, you can often fix it by identifying the two +parser states that are being confused, and adding something to make them +look distinct. In the above example, adding one rule to `return_spec' +as follows makes the problem go away: + + %token BOGUS + ... + %% + ... + return_spec: + type + | name ':' type + /* This rule is never used. */ + | ID BOGUS + ; + + This corrects the problem because it introduces the possibility of an +additional active rule in the context after the `ID' at the beginning of +`return_spec'. This rule is not active in the corresponding context in +a `param_spec', so the two contexts receive distinct parser states. As +long as the token `BOGUS' is never generated by `yylex', the added rule +cannot alter the way actual input is parsed. + + In this particular example, there is another way to solve the +problem: rewrite the rule for `return_spec' to use `ID' directly +instead of via `name'. This also causes the two confusing contexts to +have different sets of active rules, because the one for `return_spec' +activates the altered rule for `return_spec' rather than the one for +`name'. + + param_spec: + type + | name_list ':' type + ; + return_spec: + type + | ID ':' type + ; + + For a more detailed exposition of LALR(1) parsers and parser +generators, please see: Frank DeRemer and Thomas Pennello, Efficient +Computation of LALR(1) Look-Ahead Sets, `ACM Transactions on +Programming Languages and Systems', Vol. 4, No. 4 (October 1982), pp. +615-649 `http://doi.acm.org/10.1145/69622.357187'. + + +File: bison.info, Node: Generalized LR Parsing, Next: Memory Management, Prev: Mystery Conflicts, Up: Algorithm + +5.8 Generalized LR (GLR) Parsing +================================ + +Bison produces _deterministic_ parsers that choose uniquely when to +reduce and which reduction to apply based on a summary of the preceding +input and on one extra token of lookahead. As a result, normal Bison +handles a proper subset of the family of context-free languages. +Ambiguous grammars, since they have strings with more than one possible +sequence of reductions cannot have deterministic parsers in this sense. +The same is true of languages that require more than one symbol of +lookahead, since the parser lacks the information necessary to make a +decision at the point it must be made in a shift-reduce parser. +Finally, as previously mentioned (*note Mystery Conflicts::), there are +languages where Bison's particular choice of how to summarize the input +seen so far loses necessary information. + + When you use the `%glr-parser' declaration in your grammar file, +Bison generates a parser that uses a different algorithm, called +Generalized LR (or GLR). A Bison GLR parser uses the same basic +algorithm for parsing as an ordinary Bison parser, but behaves +differently in cases where there is a shift-reduce conflict that has not +been resolved by precedence rules (*note Precedence::) or a +reduce-reduce conflict. When a GLR parser encounters such a situation, +it effectively _splits_ into a several parsers, one for each possible +shift or reduction. These parsers then proceed as usual, consuming +tokens in lock-step. Some of the stacks may encounter other conflicts +and split further, with the result that instead of a sequence of states, +a Bison GLR parsing stack is what is in effect a tree of states. + + In effect, each stack represents a guess as to what the proper parse +is. Additional input may indicate that a guess was wrong, in which case +the appropriate stack silently disappears. Otherwise, the semantics +actions generated in each stack are saved, rather than being executed +immediately. When a stack disappears, its saved semantic actions never +get executed. When a reduction causes two stacks to become equivalent, +their sets of semantic actions are both saved with the state that +results from the reduction. We say that two stacks are equivalent when +they both represent the same sequence of states, and each pair of +corresponding states represents a grammar symbol that produces the same +segment of the input token stream. + + Whenever the parser makes a transition from having multiple states +to having one, it reverts to the normal LALR(1) parsing algorithm, +after resolving and executing the saved-up actions. At this +transition, some of the states on the stack will have semantic values +that are sets (actually multisets) of possible actions. The parser +tries to pick one of the actions by first finding one whose rule has +the highest dynamic precedence, as set by the `%dprec' declaration. +Otherwise, if the alternative actions are not ordered by precedence, +but there the same merging function is declared for both rules by the +`%merge' declaration, Bison resolves and evaluates both and then calls +the merge function on the result. Otherwise, it reports an ambiguity. + + It is possible to use a data structure for the GLR parsing tree that +permits the processing of any LALR(1) grammar in linear time (in the +size of the input), any unambiguous (not necessarily LALR(1)) grammar in +quadratic worst-case time, and any general (possibly ambiguous) +context-free grammar in cubic worst-case time. However, Bison currently +uses a simpler data structure that requires time proportional to the +length of the input times the maximum number of stacks required for any +prefix of the input. Thus, really ambiguous or nondeterministic +grammars can require exponential time and space to process. Such badly +behaving examples, however, are not generally of practical interest. +Usually, nondeterminism in a grammar is local--the parser is "in doubt" +only for a few tokens at a time. Therefore, the current data structure +should generally be adequate. On LALR(1) portions of a grammar, in +particular, it is only slightly slower than with the default Bison +parser. + + For a more detailed exposition of GLR parsers, please see: Elizabeth +Scott, Adrian Johnstone and Shamsa Sadaf Hussain, Tomita-Style +Generalised LR Parsers, Royal Holloway, University of London, +Department of Computer Science, TR-00-12, +`http://www.cs.rhul.ac.uk/research/languages/publications/tomita_style_1.ps', +(2000-12-24). + + +File: bison.info, Node: Memory Management, Prev: Generalized LR Parsing, Up: Algorithm + +5.9 Memory Management, and How to Avoid Memory Exhaustion +========================================================= + +The Bison parser stack can run out of memory if too many tokens are +shifted and not reduced.

This value is the maximum number of +tokens that can be shifted (and not reduced) before overflow. + + The stack space allowed is not necessarily allocated.

For example, a compiler should recover sufficiently to parse the +rest of the input file and check it for errors; a calculator should +accept another expression. + + In a simple interactive command parser where each input is one line, +it may be sufficient to allow `yyparse' to return 1 on error and have +the caller ignore the rest of the input line when that happens (and +then call `yyparse' again). But this is inadequate for a compiler, +because it forgets all the syntactic context leading up to the error. +A syntax error deep within a function in the compiler input should not +cause the compiler to treat the following line like the beginning of a +source file. + + You can define how to recover from a syntax error by writing rules to +recognize the special token `error'. This is a terminal symbol that is +always defined (you need not declare it) and reserved for error +handling. The Bison parser generates an `error' token whenever a +syntax error happens; if you have provided a rule to recognize this +token in the current context, the parse can continue. + + For example: + + stmnts: /* empty string */ + | stmnts '\n' + | stmnts exp '\n' + | stmnts error '\n' + + The fourth rule in this example says that an error followed by a +newline makes a valid addition to any `stmnts'. + + What happens if a syntax error occurs in the middle of an `exp'? The +error recovery rule, interpreted strictly, applies to the precise +sequence of a `stmnts', an `error' and a newline. If an error occurs in +the middle of an `exp', there will probably be some additional tokens +and subexpressions on the stack after the last `stmnts', and there will +be tokens to read before the next newline. So the rule is not +applicable in the ordinary way. + + But Bison can force the situation to fit the rule, by discarding +part of the semantic context and part of the input. First it discards +states and objects from the stack until it gets back to a state in +which the `error' token is acceptable. (This means that the +subexpressions already parsed are discarded, back to the last complete +`stmnts'.) At this point the `error' token can be shifted. Then, if +the old lookahead token is not acceptable to be shifted next, the +parser reads tokens and discards them until it finds a token which is +acceptable. In this example, Bison reads and discards input until the +next newline so that the fourth rule can apply. Note that discarded +symbols are possible sources of memory leaks, see *note Freeing +Discarded Symbols: Destructor Decl, for a means to reclaim this memory. + + The choice of error rules in the grammar is a choice of strategies +for error recovery. A simple and useful strategy is simply to skip the +rest of the current input line or current statement if an error is +detected: + + stmnt: error ';' /* On error, skip until ';' is read. */ + + It is also useful to recover to the matching close-delimiter of an +opening-delimiter that has already been parsed. Otherwise the +close-delimiter will probably appear to be unmatched, and generate +another, spurious error message: + + primary: '(' expr ')' + | '(' error ')' + ... + ; + + Error recovery strategies are necessarily guesses. When they guess +wrong, one syntax error often leads to another. In the above example, +the error recovery rule guesses that an error is due to bad input +within one `stmnt'. Suppose that instead a spurious semicolon is +inserted in the middle of a valid `stmnt'. After the error recovery +rule recovers from the first error, another syntax error will be found +straightaway, since the text following the spurious semicolon is also +an invalid `stmnt'. + + To prevent an outpouring of error messages, the parser will output +no error message for another syntax error that happens shortly after +the first; only after three consecutive input tokens have been +successfully shifted will error messages resume. + + Note that rules which accept the `error' token may have actions, just +as any other rules can. + + You can make error messages resume immediately by using the macro +`yyerrok' in an action. If you do this in the error rule's action, no +error messages will be suppressed. This macro requires no arguments; +`yyerrok;' is a valid C statement. + + The previous lookahead token is reanalyzed immediately after an +error. If this is unacceptable, then the macro `yyclearin' may be used +to clear this token. Write the statement `yyclearin;' in the error +rule's action. *Note Special Features for Use in Actions: Action +Features. + + For example, suppose that on a syntax error, an error handling +routine is called that advances the input stream to some point where +parsing should once again commence. The next symbol returned by the +lexical scanner is probably correct. The previous lookahead token +ought to be discarded with `yyclearin;'. + + The expression `YYRECOVERING ()' yields 1 when the parser is +recovering from a syntax error, and 0 otherwise. Syntax error +diagnostics are suppressed while recovering from a syntax error. + + +File: bison.info, Node: Context Dependency, Next: Debugging, Prev: Error Recovery, Up: Top + +7 Handling Context Dependencies +******************************* + +The Bison paradigm is to parse tokens first, then group them into larger +syntactic units. In many languages, the meaning of a token is affected +by its context. Although this violates the Bison paradigm, certain +techniques (known as "kludges") may enable you to write Bison parsers +for such languages. + +* Menu: + +* Semantic Tokens:: Token parsing can depend on the semantic context. +* Lexical Tie-ins:: Token parsing can depend on the syntactic context. +* Tie-in Recovery:: Lexical tie-ins have implications for how + error recovery rules must be written. + + (Actually, "kludge" means any technique that gets its job done but is +neither clean nor robust.) + + +File: bison.info, Node: Semantic Tokens, Next: Lexical Tie-ins, Up: Context Dependency + +7.1 Semantic Info in Token Types +================================ + +The C language has a context dependency: the way an identifier is used +depends on what its current meaning is. For example, consider this: + + foo (x); + + This looks like a function call statement, but if `foo' is a typedef +name, then this is actually a declaration of `x'. How can a Bison +parser for C decide how to parse this input? + + The method used in GNU C is to have two different token types, +`IDENTIFIER' and `TYPENAME'. When `yylex' finds an identifier, it +looks up the current declaration of the identifier in order to decide +which token type to return: `TYPENAME' if the identifier is declared as +a typedef, `IDENTIFIER' otherwise. + + The grammar rules can then express the context dependency by the +choice of token type to recognize. `IDENTIFIER' is accepted as an +expression, but `TYPENAME' is not. `TYPENAME' can start a declaration, +but `IDENTIFIER' cannot. In contexts where the meaning of the +identifier is _not_ significant, such as in declarations that can +shadow a typedef name, either `TYPENAME' or `IDENTIFIER' is +accepted--there is one rule for each of the two token types. + + This technique is simple to use if the decision of which kinds of +identifiers to allow is made at a place close to where the identifier is +parsed. But in C this is not always so: C allows a declaration to +redeclare a typedef name provided an explicit type has been specified +earlier: + + typedef int foo, bar; + int baz (void) + { + static bar (bar); /* redeclare `bar' as static variable */ + extern foo foo (foo); /* redeclare `foo' as function */ + return foo (bar); + } + + Unfortunately, the name being declared is separated from the +declaration construct itself by a complicated syntactic structure--the +"declarator". + + As a result, part of the Bison parser for C needs to be duplicated, +with all the nonterminal names changed: once for parsing a declaration +in which a typedef name can be redefined, and once for parsing a +declaration in which that can't be done. Here is a part of the +duplication, with actions omitted for brevity: + + initdcl: + declarator maybeasm '=' + init + | declarator maybeasm + ; + + notype_initdcl: + notype_declarator maybeasm '=' + init + | notype_declarator maybeasm + ; + +Here `initdcl' can redeclare a typedef name, but `notype_initdcl' +cannot. The distinction between `declarator' and `notype_declarator' +is the same sort of thing. + + There is some similarity between this technique and a lexical tie-in +(described next), in that information which alters the lexical analysis +is changed during parsing by other parts of the program. The +difference is here the information is global, and is used for other +purposes in the program. A true lexical tie-in has a special-purpose +flag controlled by the syntactic context. + + +File: bison.info, Node: Lexical Tie-ins, Next: Tie-in Recovery, Prev: Semantic Tokens, Up: Context Dependency + +7.2 Lexical Tie-ins +=================== + +One way to handle context-dependency is the "lexical tie-in": a flag +which is set by Bison actions, whose purpose is to alter the way tokens +are parsed. + + For example, suppose we have a language vaguely like C, but with a +special construct `hex (HEX-EXPR)'. After the keyword `hex' comes an +expression in parentheses in which all integers are hexadecimal. In +particular, the token `a1b' must be treated as an integer rather than +as an identifier if it appears in that context. Here is how you can do +it: + + %{ + int hexflag; + int yylex (void); + void yyerror (char const *); + %} + %% + ... + expr: IDENTIFIER + | constant + | HEX '(' + { hexflag = 1; } + expr ')' + { hexflag = 0; + $$ = $4; } + | expr '+' expr + { $$ = make_sum ($1, $3); } + ... + ; + + constant: + INTEGER + | STRING + ; + +Here we assume that `yylex' looks at the value of `hexflag'; when it is +nonzero, all integers are parsed in hexadecimal, and tokens starting +with letters are parsed as integers if possible. + + The declaration of `hexflag' shown in the prologue of the parser file +is needed to make it accessible to the actions (*note The Prologue: +Prologue.). You must also write the code in `yylex' to obey the flag. + + +File: bison.info, Node: Tie-in Recovery, Prev: Lexical Tie-ins, Up: Context Dependency + +7.3 Lexical Tie-ins and Error Recovery +====================================== + +Lexical tie-ins make strict demands on any error recovery rules you +have. *Note Error Recovery::. + + The reason for this is that the purpose of an error recovery rule is +to abort the parsing of one construct and resume in some larger +construct. For example, in C-like languages, a typical error recovery +rule is to skip tokens until the next semicolon, and then start a new +statement, like this: + + stmt: expr ';' + | IF '(' expr ')' stmt { ... } + ... + error ';' + { hexflag = 0; } + ; + + If there is a syntax error in the middle of a `hex (EXPR)' +construct, this error rule will apply, and then the action for the +completed `hex (EXPR)' will never run. So `hexflag' would remain set +for the entire rest of the input, or until the next `hex' keyword, +causing identifiers to be misinterpreted as integers. + + To avoid this problem the error recovery rule itself clears +`hexflag'. + + There may also be an error recovery rule that works within +expressions. For example, there could be a rule which applies within +parentheses and skips to the close-parenthesis: + + expr: ... + | '(' expr ')' + { $$ = $2; } + | '(' error ')' + ... + + If this rule acts within the `hex' construct, it is not going to +abort that construct (since it applies to an inner level of parentheses +within the construct). Therefore, it should not clear the flag: the +rest of the `hex' construct should be parsed with the flag still in +effect. + + What if there is an error recovery rule which might abort out of the +`hex' construct or might not, depending on circumstances? There is no +way you can write the action to determine whether a `hex' construct is +being aborted or not. So if you are using a lexical tie-in, you had +better make sure your error recovery rules are not of this kind. Each +rule must be such that you can be sure that it always will, or always +won't, have to clear the flag. + + +File: bison.info, Node: Debugging, Next: Invocation, Prev: Context Dependency, Up: Top + +8 Debugging Your Parser +*********************** + +Developing a parser can be a challenge, especially if you don't +understand the algorithm (*note The Bison Parser Algorithm: +Algorithm.).

The +conflict means that either the grammar is ambiguous, or the parser lacks +information to make the right decision. Indeed the grammar is +ambiguous, as, since we did not specify the precedence of `/', the +sentence `NUM + NUM / NUM' can be parsed as `NUM + (NUM / NUM)', which +corresponds to shifting `/', or as `(NUM + NUM) / NUM', which +corresponds to reducing rule 1. + + Because in LALR(1) parsing a single decision can be made, Bison +arbitrarily chose to disable the reduction, see *note Shift/Reduce +Conflicts: Shift/Reduce. Discarded actions are reported in between +square brackets. + + Note that all the previous states had a single possible action: +either shifting the next token and going to the corresponding state, or +reducing a single rule. In the other cases, i.e., when shifting _and_ +reducing is possible or when _several_ reductions are possible, the +lookahead is required to select the action. State 8 is one such state: +if the lookahead is `*' or `/' then the action is shifting, otherwise +the action is reducing rule 1.

This is compliant with POSIX Yacc. You could use + `-DYYDEBUG=1' as a compiler option or you could put `#define + YYDEBUG 1' in the prologue of the grammar file (*note The + Prologue: Prologue.). + +the option `-t', `--debug' + Use the `-t' option when you run Bison (*note Invoking Bison: + Invocation.). This is POSIX compliant too. + +the directive `%debug' + Add the `%debug' directive (*note Bison Declaration Summary: Decl + Summary.). This is a Bison extension, which will prove useful + when Bison will output parsers for languages that don't use a + preprocessor. Unless POSIX and Yacc portability matter to you, + this is the preferred solution. + + We suggest that you always enable the debug option so that debugging +is always possible. + + The trace facility outputs messages with macro calls of the form +`YYFPRINTF (stderr, FORMAT, ARGS)' where FORMAT and ARGS are the usual +`printf' format and variadic arguments. If you define `YYDEBUG' to a +nonzero value but do not define `YYFPRINTF', `' is +automatically included and `YYFPRINTF' is defined to `fprintf'. + + Once you have compiled the program with trace facilities, the way to +request a trace is to store a nonzero value in the variable `yydebug'. +You can do this by making the C code do it (in `main', perhaps), or you +can alter the value with a C debugger. + + Each step taken by the parser when `yydebug' is nonzero produces a +line or two of trace information, written on `stderr'. The trace +messages tell you these things: + + * Each time the parser calls `yylex', what kind of token was read. + + * Each time a token is shifted, the depth and complete contents of + the state stack (*note Parser States::). + + * Each time a rule is reduced, which rule it is, and the complete + contents of the state stack afterward. + + To make sense of this information, it helps to refer to the listing +file produced by the Bison `-v' option (*note Invoking Bison: +Invocation.). This file shows the meaning of each state in terms of +positions in various rules, and also what each state will do with each +possible input token. As you read the successive trace messages, you +can see that the parser is functioning according to its specification in +the listing file. Eventually you will arrive at the place where +something undesirable happens, and you will see which parts of the +grammar are to blame. + + The parser file is a C program and you can use C debuggers on it, +but it's not easy to interpret what it is doing. The parser function +is a finite-state machine interpreter, and aside from the actions it +executes the same code over and over. Only the values of variables +show where in the grammar it is working. + + The debugging information normally gives the token type of each token +read, but not its semantic value. You can optionally define a macro +named `YYPRINT' to provide a way to print the value. If you define +`YYPRINT', it should take three arguments. The parser will pass a +standard I/O stream, the numeric code for the token type, and the token +value (from `yylval'). + + Here is an example of `YYPRINT' suitable for the multi-function +calculator (*note Declarations for `mfcalc': Mfcalc Declarations.): + + %{ + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(file, type, value) print_token_value (file, type, value) + %} + + ... %% ... %% ... + + static void + print_token_value (FILE *file, int type, YYSTYPE value) + { + if (type == VAR) + fprintf (file, "%s", value.tptr->name); + else if (type == NUM) + fprintf (file, "%d", value.val); + } + + +File: bison.info, Node: Invocation, Next: Other Languages, Prev: Debugging, Up: Top + +9 Invoking Bison +**************** + +The usual way to invoke Bison is as follows: + + bison INFILE + + Here INFILE is the grammar file name, which usually ends in `.y'. +The parser file's name is made by replacing the `.y' with `.tab.c' and +removing any leading directory.

More user +feedback will help to stabilize it.) + + The Java parser skeletons are selected using the `%language "Java"' +directive or the `-L java'/`--language=java' option. + + When generating a Java parser, `bison BASENAME.y' will create a +single Java source file named `BASENAME.java'.

The entire output file name can be +changed by the `%output' directive or the `-o'/`--output' option. The +output file contains a single class for the parser. + + You can create documentation for generated parsers using Javadoc. + + Contrary to C parsers, Java parsers do not use global variables; the +state of the parser is always local to an instance of the parser class. +Therefore, all Java parsers are "pure", and the `%pure-parser' and +`%define api.pure' directives does not do anything when used in Java. + + Push parsers are currently unsupported in Java and `%define +api.push_pull' have no effect. + + GLR parsers are currently unsupported in Java.

To +improve the type safety of the parser, you can declare the common +superclass of all the semantic values using the `%define stype' +directive. For example, after the following declaration: + + %define stype "ASTNode" + +any `%type' or `%token' specifying a semantic type which is not a +subclass of ASTNode, will cause a compile-time error. + + Types used in the directives may be qualified with a package name. +Primitive data types are accepted for Java version 1.5 or later. Note +that in this case the autoboxing feature of Java 1.5 will be used. +Generic types may not be used; this is due to a limitation in the +implementation of Bison, and may change in future releases. + + Java parsers do not support `%destructor', since the language adopts +garbage collection. The parser will try to hold references to semantic +values for as little time as needed. + + Java parsers do not support `%printer', as `toString()' can be used +to print the semantic values.

An +auxiliary user-defined class defines a "position", a single point in a +file; Bison itself defines a class representing a "location", a range +composed of a pair of positions (possibly spanning several files). The +location class is an inner class of the parser; the name is `Location' +by default, and may also be renamed using `%define location_type +"CLASS-NAME'. + + The location class treats the position as a completely opaque value. +By default, the class name is `Position', but this can be changed with +`%define position_type "CLASS-NAME"'. This class must be supplied by +the user. + + -- Instance Variable of Location: Position begin + -- Instance Variable of Location: Position end + The first, inclusive, position of the range, and the first beyond. + + -- Constructor on Location: Location (Position LOC) + Create a `Location' denoting an empty range located at a given + point. + + -- Constructor on Location: Location (Position BEGIN, Position END) + Create a `Location' from the endpoints of the range. + + -- Method on Location: String toString () + Prints the range represented by the location. For this to work + properly, the position class should override the `equals' and + `toString' methods appropriately. + + +File: bison.info, Node: Java Parser Interface, Next: Java Scanner Interface, Prev: Java Location Values, Up: Java Parsers + +10.2.4 Java Parser Interface +---------------------------- + +The name of the generated parser class defaults to `YYParser'. The +`YY' prefix may be changed using the `%name-prefix' directive or the +`-p'/`--name-prefix' option. Alternatively, use `%define +parser_class_name "NAME"' to give a custom name to the class. The +interface of this class is detailed below. + + By default, the parser class has package visibility. A declaration +`%define public' will change to public visibility. Remember that, +according to the Java language specification, the name of the `.java' +file should match the name of the class in this case. Similarly, you +can use `abstract', `final' and `strictfp' with the `%define' +declaration to add other modifiers to the parser class. + + The Java package name of the parser class can be specified using the +`%define package' directive. The superclass and the implemented +interfaces of the parser class can be specified with the `%define +extends' and `%define implements' directives. + + The parser class defines an inner class, `Location', that is used +for location tracking (see *note Java Location Values::), and a inner +interface, `Lexer' (see *note Java Scanner Interface::). Other than +these inner class/interface, and the members described in the interface +below, all the other members and fields are preceded with a `yy' or +`YY' prefix to avoid clashes with user code. + + The parser class can be extended using the `%parse-param' directive. +Each occurrence of the directive will add a `protected final' field to +the parser class, and an argument to its constructor, which initialize +them automatically. + + Token names defined by `%token' and the predefined `EOF' token name +are added as constant fields to the parser class. + + -- Constructor on YYParser: YYParser (LEX_PARAM, ..., PARSE_PARAM, + ...) + Build a new parser object with embedded `%code lexer'.

In either case, the scanner has to implement the `Lexer' +inner interface of the parser class. + + In the first case, the body of the scanner class is placed in `%code +lexer' blocks. If you want to pass parameters from the parser +constructor to the scanner constructor, specify them with `%lex-param'; +they are passed before `%parse-param's to the constructor. + + In the second case, the scanner has to implement the `Lexer' +interface, which is defined within the parser class (e.g., +`YYParser.Lexer'). The constructor of the parser object will then +accept an object implementing the interface; `%lex-param' is not used +in this case. + + In both cases, the scanner has to implement the following methods. + + -- Method on Lexer: void yyerror (Location LOC, String MSG) + This method is defined by the user to emit an error message. The + first parameter is omitted if location tracking is not active. + Its type can be changed using `%define location_type "CLASS-NAME".' + + -- Method on Lexer: int yylex () + Return the next token. Its type is the return value, its semantic + value and location are saved and returned by the ther methods in + the interface. + + Use `%define lex_throws' to specify any uncaught exceptions. + Default is `java.io.IOException'. + + -- Method on Lexer: Position getStartPos () + -- Method on Lexer: Position getEndPos () + Return respectively the first position of the last token that + `yylex' returned, and the first position beyond it. These methods + are not needed unless location tracking is active. + + The return type can be changed using `%define position_type + "CLASS-NAME".' + + -- Method on Lexer: Object getLVal () + Return the semantical value of the last token that yylex returned. + + The return type can be changed using `%define stype "CLASS-NAME".' + + +File: bison.info, Node: Java Action Features, Next: Java Differences, Prev: Java Scanner Interface, Up: Java Parsers + +10.2.6 Special Features for Use in Java Actions +----------------------------------------------- + +The following special constructs can be uses in Java actions.

This +section summarizes these differences. + + * Java lacks a preprocessor, so the `YYERROR', `YYACCEPT', `YYABORT' + symbols (*note Table of Symbols::) cannot obviously be macros. + Instead, they should be preceded by `return' when they appear in + an action. The actual definition of these symbols is opaque to + the Bison grammar, and it might change in the future. The only + meaningful operation that you can do, is to return them. See + *note Java Action Features::. + + Note that of these three symbols, only `YYACCEPT' and `YYABORT' + will cause a return from the `yyparse' method(1). + + * Java lacks unions, so `%union' has no effect. Instead, semantic + values have a common base type: `Object' or as specified by + `%define stype'. Angle backets on `%token', `type', `$N' and `$$' + specify subtypes rather than fields of an union. The type of + `$$', even with angle brackets, is the base type since Java casts + are not allow on the left-hand side of assignments. Also, `$N' + and `@N' are not allowed on the left-hand side of assignments. See + *note Java Semantic Values:: and *note Java Action Features::. + + * The prolog declarations have a different meaning than in C/C++ + code. + `%code imports' + blocks are placed at the beginning of the Java source code. + They may include copyright notices. For a `package' + declarations, it is suggested to use `%define package' + instead. + + unqualified `%code' + blocks are placed inside the parser class. + + `%code lexer' + blocks, if specified, should include the implementation of the + scanner. If there is no such block, the scanner can be any + class that implements the appropriate interface (see *note + Java Scanner Interface::). + + Other `%code' blocks are not supported in Java parsers. In + particular, `%{ ... %}' blocks should not be used and may give an + error in future versions of Bison. + + The epilogue has the same meaning as in C/C++ code and it can be + used to define other classes used by the parser _outside_ the + parser class. + + ---------- Footnotes ---------- + + (1) Java parsers include the actions in a separate method than +`yyparse' in order to have an intuitive syntax that corresponds to +these C macros. + + +File: bison.info, Node: Java Declarations Summary, Prev: Java Differences, Up: Java Parsers + +10.2.8 Java Declarations Summary +-------------------------------- + +This summary only include declarations specific to Java or have special +meaning when used in a Java parser. + + -- Directive: %language "Java" + Generate a Java class for the parser. + + -- Directive: %lex-param {TYPE NAME} + A parameter for the lexer class defined by `%code lexer' _only_, + added as parameters to the lexer constructor and the parser + constructor that _creates_ a lexer.

How can I reset the error flag of `yyparse'? + +or + + My parser includes support for an `#include'-like feature, in + which case I run `yyparse' from `yyparse'. This fails + although I did specify `%define api.pure'. + + These problems typically come not from Bison itself, but from +Lex-generated scanners. Because these scanners use large buffers for +speed, they might not notice a change of input file. As a +demonstration, consider the following source file, `first-line.l': + + +%{ +#include +#include +%} +%% +.*\n ECHO; return 1; +%% +int +yyparse (char const *file) +{ + yyin = fopen (file, "r"); + if (!yyin) + exit (2); + /* One token only. */ + yylex (); + if (fclose (yyin) != 0) + exit (3); + return 0; +} + +int +main (void) +{ + yyparse ("input"); + yyparse ("input"); + return 0; +} + +If the file `input' contains + + +input:1: Hello, +input:2: World! + +then instead of getting the first line twice, you get: + + $ flex -ofirst-line.c first-line.l + $ gcc -ofirst-line first-line.c -ll + $ ./first-line + input:1: Hello, + input:2: World! + + Therefore, whenever you change `yyin', you must tell the +Lex-generated scanner to discard its current buffer and switch to the +new one. This depends upon your implementation of Lex; see its +documentation for more. For Flex, it suffices to call +`YY_FLUSH_BUFFER' after each change to `yyin'. If your Flex-generated +scanner needs to read from several input streams to handle features +like include files, you might consider using Flex functions like +`yy_switch_to_buffer' that manipulate multiple input buffers. + + If your Flex-generated scanner uses start conditions (*note Start +conditions: (flex)Start conditions.), you might also want to reset the +scanner's state, i.e., go back to the initial start condition, through +a call to `BEGIN (0)'. + + +File: bison.info, Node: Strings are Destroyed, Next: Implementing Gotos/Loops, Prev: How Can I Reset the Parser, Up: FAQ + +11.3 Strings are Destroyed +========================== + + My parser seems to destroy old strings, or maybe it loses track of + them. Instead of reporting `"foo", "bar"', it reports + `"bar", "bar"', or even `"foo\nbar", "bar"'. + + This error is probably the single most frequent "bug report" sent to +Bison lists, but is only concerned with a misunderstanding of the role +of the scanner. Consider the following Lex code: + + +%{ +#include +char *yylval = NULL; +%} +%% +.* yylval = yytext; return 1; +\n /* IGNORE */ +%% +int +main () +{ + /* Similar to using $1, $2 in a Bison action. */ + char *fst = (yylex (), yylval); + char *snd = (yylex (), yylval); + printf ("\"%s\", \"%s\"\n", fst, snd); + return 0; +} + + If you compile and run this code, you get: + + $ flex -osplit-lines.c split-lines.l + $ gcc -osplit-lines split-lines.c -ll + $ printf 'one\ntwo\n' | ./split-lines + "one + two", "two" + +this is because `yytext' is a buffer provided for _reading_ in the +action, but if you want to keep it, you have to duplicate it (e.g., +using `strdup'). Note that the output may depend on how your +implementation of Lex handles `yytext'. For instance, when given the +Lex compatibility option `-l' (which triggers the option `%array') Flex +generates a different behavior: + + $ flex -l -osplit-lines.c split-lines.l + $ gcc -osplit-lines split-lines.c -ll + $ printf 'one\ntwo\n' | ./split-lines + "two", "two" + + +File: bison.info, Node: Implementing Gotos/Loops, Next: Multiple start-symbols, Prev: Strings are Destroyed, Up: FAQ + +11.4 Implementing Gotos/Loops +============================= + + My simple calculator supports variables, assignments, and functions, + but how can I implement gotos, or loops? + + Although very pedagogical, the examples included in the document blur +the distinction to make between the parser--whose job is to recover the +structure of a text and to transmit it to subsequent modules of the +program--and the processing (such as the execution) of this structure. +This works well with so called straight line programs, i.e., precisely +those that have a straightforward execution model: execute simple +instructions one after the others. + + If you want a richer model, you will probably need to use the parser +to construct a tree that does represent the structure it has recovered; +this tree is usually called the "abstract syntax tree", or "AST" for +short. Then, walking through this tree, traversing it in various ways, +will enable treatments such as its execution or its translation, which +will result in an interpreter or a compiler. + + This topic is way beyond the scope of this manual, and the reader is +invited to consult the dedicated literature. + + +File: bison.info, Node: Multiple start-symbols, Next: Secure? Conform?, Prev: Implementing Gotos/Loops, Up: FAQ + +11.5 Multiple start-symbols +=========================== + + I have several closely related grammars, and I would like to share their + implementations. In fact, I could use a single grammar but with + multiple entry points. + + Bison does not support multiple start-symbols, but there is a very +simple means to simulate them. If `foo' and `bar' are the two pseudo +start-symbols, then introduce two new tokens, say `START_FOO' and +`START_BAR', and use them as switches from the real start-symbol: + + %token START_FOO START_BAR; + %start start; + start: START_FOO foo + | START_BAR bar; + + These tokens prevents the introduction of new conflicts. As far as +the parser goes, that is all that is needed. + + Now the difficult part is ensuring that the scanner will send these +tokens first. If your scanner is hand-written, that should be +straightforward. If your scanner is generated by Lex, them there is +simple means to do it: recall that anything between `%{ ... %}' after +the first `%%' is copied verbatim in the top of the generated `yylex' +function. Make sure a variable `start_token' is available in the +scanner (e.g., a global variable or using `%lex-param' etc.), and use +the following: + + /* Prologue. */ + %% + %{ + if (start_token) + { + int t = start_token; + start_token = 0; + return t; + } + %} + /* The rules. */ + + +File: bison.info, Node: Secure?

Secondarily, this License preserves for the + author and publisher a way to get credit for their work, while not + being considered responsible for modifications made by others. + + This License is a kind of "copyleft", which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. + We recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work, in any medium, + that contains a notice placed by the copyright holder saying it + can be distributed under the terms of this License. Such a notice + grants a world-wide, royalty-free license, unlimited in duration, + to use that work under the conditions stated herein. The + "Document", below, refers to any such manual or work. Any member + of the public is a licensee, and is addressed as "you". You + accept the license if you copy, modify or distribute the work in a + way requiring permission under copyright law. + + A "Modified Version" of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A "Secondary Section" is a named appendix or a front-matter section + of the Document that deals exclusively with the relationship of the + publishers or authors of the Document to the Document's overall + subject (or to related matters) and contains nothing that could + fall directly within that overall subject. (Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in + the notice that says that the Document is released under this + License. If a section does not fit the above definition of + Secondary then it is not allowed to be designated as Invariant. + The Document may contain zero Invariant Sections. If the Document + does not identify any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images + composed of pixels) generic paint programs or (for drawings) some + widely available drawing editor, and that is suitable for input to + text formatters or for automatic translation to a variety of + formats suitable for input to text formatters. A copy made in an + otherwise Transparent file format whose markup, or absence of + markup, has been arranged to thwart or discourage subsequent + modification by readers is not Transparent. An image format is + not Transparent if used for any substantial amount of text. A + copy that is not "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and + standard-conforming simple HTML, PostScript or PDF designed for + human modification. Examples of transparent image formats include + PNG, XCF and JPG. Opaque formats include proprietary formats that + can be read and edited only by proprietary word processors, SGML or + XML for which the DTD and/or processing tools are not generally + available, and the machine-generated HTML, PostScript or PDF + produced by some word processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow + the conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the + title equally prominent and visible. You may add other material + on the covers in addition. Copying with changes limited to the + covers, as long as they preserve the title of the Document and + satisfy these conditions, can be treated as verbatim copying in + other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a + machine-readable Transparent copy along with each Opaque copy, or + state in or with each Opaque copy a computer-network location from + which the general network-using public has access to download + using public-standard network protocols a complete Transparent + copy of the Document, free of added material. If you use the + latter option, you must take reasonably prudent steps, when you + begin distribution of Opaque copies in quantity, to ensure that + this Transparent copy will remain thus accessible at the stated + location until at least one year after the last time you + distribute an Opaque copy (directly or through your agents or + retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of + copies, to give them a chance to provide you with an updated + version of the Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with + the Modified Version filling the role of the Document, thus + licensing distribution and modification of the Modified Version to + whoever possesses a copy of it. In addition, you must do these + things in the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of + previous versions (which should, if there were any, be listed + in the History section of the Document). You may use the + same title as a previous version if the original publisher of + that version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on + the Title Page. If there is no section Entitled "History" in + the Document, create one stating the title, year, authors, + and publisher of the Document as given on its Title Page, + then add an item describing the Modified Version as stated in + the previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in + the "History" section. You may omit a network location for a + work that was published at least four years before the + Document itself, or if the original publisher of the version + it refers to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the + section all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section + titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option + designate some or all of these sections as invariant. To do this, + add their titles to the list of Invariant Sections in the Modified + Version's license notice. These titles must be distinct from any + other section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end + of the list of Cover Texts in the Modified Version. Only one + passage of Front-Cover Text and one of Back-Cover Text may be + added by (or through arrangements made by) any one entity. If the + Document already includes a cover text for the same cover, + previously added by you or by arrangement made by the same entity + you are acting on behalf of, you may not add another; but you may + replace the old one, on explicit permission from the previous + publisher that added the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination + all of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the + documents in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow + this License in all other respects regarding verbatim copying of + that document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of + a storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided for under this License. Any other + attempt to copy, modify, sublicense or distribute the Document is + void, and will automatically terminate your rights under this + License. However, parties who have received copies, or rights, + from you under this License will not have their licenses + terminated so long as such parties remain in full compliance. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + `http://www.gnu.org/copyleft/'. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If + the Document does not specify a version number of this License, + you may choose any version ever published (not as a draft) by the + Free Software Foundation. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts. A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have Invariant Sections, Front-Cover Texts and Back-Cover +Texts, replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with + the Front-Cover Texts being LIST, and with the Back-Cover Texts + being LIST. + + If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + + If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, to +permit their use in free software. + + +File: bison.info, Node: Index, Prev: Copying This Manual, Up: Top + +Index +***** + +[index] +* Menu: + +* $ <1>: Table of Symbols.

Once you are proficient with +Bison, you can use it to develop a wide range of language parsers, from those +used in simple desk calculators to complex programming languages. + +Bison is upward compatible with Yacc: all properly-written Yacc grammars +ought to work with Bison with no change. Anyone familiar with Yacc +should be able to use Bison with little trouble. You need to be fluent in +C or C++ programming in order to use Bison or to understand this manual. + +We begin with tutorial chapters that explain the basic concepts of using +Bison and show three explained examples, each building on the last. If you +don't know Bison or Yacc, start by reading these chapters. Reference +chapters follow which describe specific aspects of Bison in detail. + +Bison was written primarily by Robert Corbett; Richard Stallman made it +Yacc-compatible. Wilfred Hansen of Carnegie Mellon University added +multi-character string literals and other features. + +This edition corresponds to version @value{VERSION} of Bison. + +@node Conditions +@unnumbered Conditions for Using Bison + +The distribution terms for Bison-generated parsers permit using the +parsers in nonfree programs. Before Bison version 2.2, these extra +permissions applied only when Bison was generating @acronym{LALR}(1) +parsers in C@. And before Bison version 1.24, Bison-generated +parsers could be used only in programs that were free software. + +The other @acronym{GNU} programming tools, such as the @acronym{GNU} C +compiler, have never +had such a requirement. They could always be used for nonfree +software. The reason Bison was different was not due to a special +policy decision; it resulted from applying the usual General Public +License to all of the Bison source code. + +The output of the Bison utility---the Bison parser file---contains a +verbatim copy of a sizable piece of Bison, which is the code for the +parser's implementation. (The actions from your grammar are inserted +into this implementation at one point, but most of the rest of the +implementation is not changed.) When we applied the @acronym{GPL} +terms to the skeleton code for the parser's implementation, +the effect was to restrict the use of Bison output to free software. + +We didn't change the terms because of sympathy for people who want to +make software proprietary. @strong{Software should be free.} But we +concluded that limiting Bison's use to free software was doing little to +encourage people to make other software free.

This means that you specify one or more +@dfn{syntactic groupings} and give rules for constructing them from their +parts. For example, in the C language, one kind of grouping is called an +`expression'. One rule for making an expression might be, ``An expression +can be made of a minus sign and another expression''. Another would be, +``An expression can be an integer''.

Strictly speaking, that is a description of an +@acronym{LR}(1) grammar, and @acronym{LALR}(1) involves additional +restrictions that are +hard to explain simply; but it is rare in actual practice to find an +@acronym{LR}(1) grammar that fails to be @acronym{LALR}(1). +@xref{Mystery Conflicts, ,Mysterious Reduce/Reduce Conflicts}, for +more information on this. + +@cindex @acronym{GLR} parsing +@cindex generalized @acronym{LR} (@acronym{GLR}) parsing +@cindex ambiguous grammars +@cindex nondeterministic parsing + +Parsers for @acronym{LALR}(1) grammars are @dfn{deterministic}, meaning +roughly that the next grammar rule to apply at any point in the input is +uniquely determined by the preceding input and a fixed, finite portion +(called a @dfn{lookahead}) of the remaining input. A context-free +grammar can be @dfn{ambiguous}, meaning that there are multiple ways to +apply the grammar rules to get the same inputs. Even unambiguous +grammars can be @dfn{nondeterministic}, meaning that no fixed +lookahead always suffices to determine the next grammar rule to apply. +With the proper declarations, Bison is also able to parse these more +general context-free grammars, using a technique known as @acronym{GLR} +parsing (for Generalized @acronym{LR}). Bison's @acronym{GLR} parsers +are able to handle any context-free grammar for which the number of +possible parses of any given string is finite. + +@cindex symbols (abstract) +@cindex token +@cindex syntactic grouping +@cindex grouping, syntactic +In the formal grammatical rules for a language, each kind of syntactic +unit or grouping is named by a @dfn{symbol}. Those which are built by +grouping smaller constructs according to grammatical rules are called +@dfn{nonterminal symbols}; those which can't be subdivided are called +@dfn{terminal symbols} or @dfn{token types}. We call a piece of input +corresponding to a single terminal symbol a @dfn{token}, and a piece +corresponding to a single nonterminal symbol a @dfn{grouping}. + +We can use the C language as an example of what symbols, terminal and +nonterminal, mean. The tokens of C are identifiers, constants (numeric +and string), and the various keywords, arithmetic operators and +punctuation marks. So the terminal symbols of a grammar for C include +`identifier', `number', `string', plus one symbol for each keyword, +operator or punctuation mark: `if', `return', `const', `static', `int', +`char', `plus-sign', `open-brace', `close-brace', `comma' and many more. +(These tokens can be subdivided into characters, but that is a matter of +lexicography, not grammar.) + +Here is a simple C function subdivided into tokens: + +@ifinfo +@example +int /* @r{keyword `int'} */ +square (int x) /* @r{identifier, open-paren, keyword `int',} + @r{identifier, close-paren} */ +@{ /* @r{open-brace} */ + return x * x; /* @r{keyword `return', identifier, asterisk,} + @r{identifier, semicolon} */ +@} /* @r{close-brace} */ +@end example +@end ifinfo +@ifnotinfo +@example +int /* @r{keyword `int'} */ +square (int x) /* @r{identifier, open-paren, keyword `int', identifier, close-paren} */ +@{ /* @r{open-brace} */ + return x * x; /* @r{keyword `return', identifier, asterisk, identifier, semicolon} */ +@} /* @r{close-brace} */ +@end example +@end ifnotinfo + +The syntactic groupings of C include the expression, the statement, the +declaration, and the function definition. These are represented in the +grammar of C by nonterminal symbols `expression', `statement', +`declaration' and `function definition'. The full grammar uses dozens of +additional language constructs, each with its own nonterminal symbol, in +order to express the meanings of these four. The example above is a +function definition; it contains one declaration, and one statement. In +the statement, each @samp{x} is an expression and so is @samp{x * x}. + +Each nonterminal symbol must have grammatical rules showing how it is made +out of simpler constructs. For example, one kind of C statement is the +@code{return} statement; this would be described with a grammar rule which +reads informally as follows: + +@quotation +A `statement' can be made of a `return' keyword, an `expression' and a +`semicolon'. +@end quotation + +@noindent +There would be many other rules for `statement', one for each kind of +statement in C. + +@cindex start symbol +One nonterminal symbol must be distinguished as the special one which +defines a complete utterance in the language. It is called the @dfn{start +symbol}. In a compiler, this means a complete input program. In the C +language, the nonterminal symbol `sequence of definitions and declarations' +plays this role. + +For example, @samp{1 + 2} is a valid C expression---a valid part of a C +program---but it is not valid as an @emph{entire} C program. In the +context-free grammar of C, this follows from the fact that `expression' is +not the start symbol. + +The Bison parser reads a sequence of tokens as its input, and groups the +tokens using the grammar rules. If the input is valid, the end result is +that the entire token sequence reduces to a single grouping whose symbol is +the grammar's start symbol. If we use a grammar for C, the entire input +must be a `sequence of definitions and declarations'. If not, the parser +reports a syntax error. + +@node Grammar in Bison +@section From Formal Rules to Bison Input +@cindex Bison grammar +@cindex grammar, Bison +@cindex formal grammar + +A formal grammar is a mathematical construct. To define the language +for Bison, you must write a file expressing the grammar in Bison syntax: +a @dfn{Bison grammar} file. @xref{Grammar File, ,Bison Grammar Files}. + +A nonterminal symbol in the formal grammar is represented in Bison input +as an identifier, like an identifier in C@. By convention, it should be +in lower case, such as @code{expr}, @code{stmt} or @code{declaration}. + +The Bison representation for a terminal symbol is also called a @dfn{token +type}. Token types as well can be represented as C-like identifiers. By +convention, these identifiers should be upper case to distinguish them from +nonterminals: for example, @code{INTEGER}, @code{IDENTIFIER}, @code{IF} or +@code{RETURN}. A terminal symbol that stands for a particular keyword in +the language should be named after that keyword converted to upper case. +The terminal symbol @code{error} is reserved for error recovery. +@xref{Symbols}. + +A terminal symbol can also be represented as a character literal, just like +a C character constant. You should do this whenever a token is just a +single character (parenthesis, plus-sign, etc.): use that same character in +a literal as the terminal symbol for that token. + +A third way to represent a terminal symbol is with a C string constant +containing several characters. @xref{Symbols}, for more information. + +The grammar rules also have an expression in Bison syntax. For example, +here is the Bison rule for a C @code{return} statement. The semicolon in +quotes is a literal character token, representing part of the C syntax for +the statement; the naked semicolon, and the colon, are Bison punctuation +used in every rule. + +@example +stmt: RETURN expr ';' + ; +@end example + +@noindent +@xref{Rules, ,Syntax of Grammar Rules}. + +@node Semantic Values +@section Semantic Values +@cindex semantic value +@cindex value, semantic + +A formal grammar selects tokens only by their classifications: for example, +if a rule mentions the terminal symbol `integer constant', it means that +@emph{any} integer constant is grammatically valid in that position. The +precise value of the constant is irrelevant to how to parse the input: if +@samp{x+4} is grammatical then @samp{x+1} or @samp{x+3989} is equally +grammatical. + +But the precise value is very important for what the input means once it is +parsed. A compiler is useless if it fails to distinguish between 4, 1 and +3989 as constants in the program! Therefore, each token in a Bison grammar +has both a token type and a @dfn{semantic value}. @xref{Semantics, +,Defining Language Semantics}, +for details. + +The token type is a terminal symbol defined in the grammar, such as +@code{INTEGER}, @code{IDENTIFIER} or @code{','}. It tells everything +you need to know to decide where the token may validly appear and how to +group it with other tokens. The grammar rules know nothing about tokens +except their types. + +The semantic value has all the rest of the information about the +meaning of the token, such as the value of an integer, or the name of an +identifier. (A token such as @code{','} which is just punctuation doesn't +need to have any semantic value.) + +For example, an input token might be classified as token type +@code{INTEGER} and have the semantic value 4. Another input token might +have the same token type @code{INTEGER} but value 3989. When a grammar +rule says that @code{INTEGER} is allowed, either of these tokens is +acceptable because each is an @code{INTEGER}. When the parser accepts the +token, it keeps track of the token's semantic value. + +Each grouping can also have a semantic value as well as its nonterminal +symbol. For example, in a calculator, an expression typically has a +semantic value that is a number. In a compiler for a programming +language, an expression typically has a semantic value that is a tree +structure describing the meaning of the expression. + +@node Semantic Actions +@section Semantic Actions +@cindex semantic actions +@cindex actions, semantic + +In order to be useful, a program must do more than parse input; it must +also produce some output based on the input. In a Bison grammar, a grammar +rule can have an @dfn{action} made up of C statements. Each time the +parser recognizes a match for that rule, the action is executed. +@xref{Actions}. + +Most of the time, the purpose of an action is to compute the semantic value +of the whole construct from the semantic values of its parts. For example, +suppose we have a rule which says an expression can be the sum of two +expressions. When the parser recognizes such a sum, each of the +subexpressions has a semantic value which describes how it was built up. +The action for this rule should create a similar sort of value for the +newly recognized larger expression. + +For example, here is a rule that says an expression can be the sum of +two subexpressions: + +@example +expr: expr '+' expr @{ $$ = $1 + $3; @} + ; +@end example + +@noindent +The action says how to produce the semantic value of the sum expression +from the values of the two subexpressions. + +@node GLR Parsers +@section Writing @acronym{GLR} Parsers +@cindex @acronym{GLR} parsing +@cindex generalized @acronym{LR} (@acronym{GLR}) parsing +@findex %glr-parser +@cindex conflicts +@cindex shift/reduce conflicts +@cindex reduce/reduce conflicts + +In some grammars, Bison's standard +@acronym{LALR}(1) parsing algorithm cannot decide whether to apply a +certain grammar rule at a given point. That is, it may not be able to +decide (on the basis of the input read so far) which of two possible +reductions (applications of a grammar rule) applies, or whether to apply +a reduction or read more of the input and apply a reduction later in the +input. These are known respectively as @dfn{reduce/reduce} conflicts +(@pxref{Reduce/Reduce}), and @dfn{shift/reduce} conflicts +(@pxref{Shift/Reduce}). + +To use a grammar that is not easily modified to be @acronym{LALR}(1), a +more general parsing algorithm is sometimes necessary. If you include +@code{%glr-parser} among the Bison declarations in your file +(@pxref{Grammar Outline}), the result is a Generalized @acronym{LR} +(@acronym{GLR}) parser. These parsers handle Bison grammars that +contain no unresolved conflicts (i.e., after applying precedence +declarations) identically to @acronym{LALR}(1) parsers. However, when +faced with unresolved shift/reduce and reduce/reduce conflicts, +@acronym{GLR} parsers use the simple expedient of doing both, +effectively cloning the parser to follow both possibilities. Each of +the resulting parsers can again split, so that at any given time, there +can be any number of possible parses being explored. The parsers +proceed in lockstep; that is, all of them consume (shift) a given input +symbol before any of them proceed to the next. Each of the cloned +parsers eventually meets one of two possible fates: either it runs into +a parsing error, in which case it simply vanishes, or it merges with +another parser, because the two of them have reduced the input to an +identical set of symbols. + +During the time that there are multiple parsers, semantic actions are +recorded, but not performed. When a parser disappears, its recorded +semantic actions disappear as well, and are never performed. When a +reduction makes two parsers identical, causing them to merge, Bison +records both sets of semantic actions. Whenever the last two parsers +merge, reverting to the single-parser case, Bison resolves all the +outstanding actions either by precedences given to the grammar rules +involved, or by performing both actions, and then calling a designated +user-defined function on the resulting values to produce an arbitrary +merged result. + +@menu +* Simple GLR Parsers:: Using @acronym{GLR} parsers on unambiguous grammars. +* Merging GLR Parses:: Using @acronym{GLR} parsers to resolve ambiguities. +* GLR Semantic Actions:: Deferred semantic actions have special concerns. +* Compiler Requirements:: @acronym{GLR} parsers require a modern C compiler. +@end menu + +@node Simple GLR Parsers +@subsection Using @acronym{GLR} on Unambiguous Grammars +@cindex @acronym{GLR} parsing, unambiguous grammars +@cindex generalized @acronym{LR} (@acronym{GLR}) parsing, unambiguous grammars +@findex %glr-parser +@findex %expect-rr +@cindex conflicts +@cindex reduce/reduce conflicts +@cindex shift/reduce conflicts + +In the simplest cases, you can use the @acronym{GLR} algorithm +to parse grammars that are unambiguous, but fail to be @acronym{LALR}(1). +Such grammars typically require more than one symbol of lookahead, +or (in rare cases) fall into the category of grammars in which the +@acronym{LALR}(1) algorithm throws away too much information (they are in +@acronym{LR}(1), but not @acronym{LALR}(1), @ref{Mystery Conflicts}). + +Consider a problem that +arises in the declaration of enumerated and subrange types in the +programming language Pascal. Here are some examples: + +@example +type subrange = lo .. hi; +type enum = (a, b, c); +@end example + +@noindent +The original language standard allows only numeric +literals and constant identifiers for the subrange bounds (@samp{lo} +and @samp{hi}), but Extended Pascal (@acronym{ISO}/@acronym{IEC} +10206) and many other +Pascal implementations allow arbitrary expressions there. This gives +rise to the following situation, containing a superfluous pair of +parentheses: + +@example +type subrange = (a) .. b; +@end example + +@noindent +Compare this to the following declaration of an enumerated +type with only one value: + +@example +type enum = (a); +@end example + +@noindent +(These declarations are contrived, but they are syntactically +valid, and more-complicated cases can come up in practical programs.) + +These two declarations look identical until the @samp{..} token. +With normal @acronym{LALR}(1) one-token lookahead it is not +possible to decide between the two forms when the identifier +@samp{a} is parsed. It is, however, desirable +for a parser to decide this, since in the latter case +@samp{a} must become a new identifier to represent the enumeration +value, while in the former case @samp{a} must be evaluated with its +current meaning, which may be a constant or even a function call. + +You could parse @samp{(a)} as an ``unspecified identifier in parentheses'', +to be resolved later, but this typically requires substantial +contortions in both semantic actions and large parts of the +grammar, where the parentheses are nested in the recursive rules for +expressions. + +You might think of using the lexer to distinguish between the two +forms by returning different tokens for currently defined and +undefined identifiers. But if these declarations occur in a local +scope, and @samp{a} is defined in an outer scope, then both forms +are possible---either locally redefining @samp{a}, or using the +value of @samp{a} from the outer scope. So this approach cannot +work. + +A simple solution to this problem is to declare the parser to +use the @acronym{GLR} algorithm. +When the @acronym{GLR} parser reaches the critical state, it +merely splits into two branches and pursues both syntax rules +simultaneously. Sooner or later, one of them runs into a parsing +error. If there is a @samp{..} token before the next +@samp{;}, the rule for enumerated types fails since it cannot +accept @samp{..} anywhere; otherwise, the subrange type rule +fails since it requires a @samp{..} token. So one of the branches +fails silently, and the other one continues normally, performing +all the intermediate actions that were postponed during the split. + +If the input is syntactically incorrect, both branches fail and the parser +reports a syntax error as usual. + +The effect of all this is that the parser seems to ``guess'' the +correct branch to take, or in other words, it seems to use more +lookahead than the underlying @acronym{LALR}(1) algorithm actually allows +for. In this example, @acronym{LALR}(2) would suffice, but also some cases +that are not @acronym{LALR}(@math{k}) for any @math{k} can be handled this way. + +In general, a @acronym{GLR} parser can take quadratic or cubic worst-case time, +and the current Bison parser even takes exponential time and space +for some grammars. In practice, this rarely happens, and for many +grammars it is possible to prove that it cannot happen. +The present example contains only one conflict between two +rules, and the type-declaration context containing the conflict +cannot be nested. So the number of +branches that can exist at any time is limited by the constant 2, +and the parsing time is still linear. + +Here is a Bison grammar corresponding to the example above. It +parses a vastly simplified form of Pascal type declarations. + +@example +%token TYPE DOTDOT ID + +@group +%left '+' '-' +%left '*' '/' +@end group + +%% + +@group +type_decl : TYPE ID '=' type ';' + ; +@end group + +@group +type : '(' id_list ')' + | expr DOTDOT expr + ; +@end group + +@group +id_list : ID + | id_list ',' ID + ; +@end group + +@group +expr : '(' expr ')' + | expr '+' expr + | expr '-' expr + | expr '*' expr + | expr '/' expr + | ID + ; +@end group +@end example + +When used as a normal @acronym{LALR}(1) grammar, Bison correctly complains +about one reduce/reduce conflict. In the conflicting situation the +parser chooses one of the alternatives, arbitrarily the one +declared first. Therefore the following correct input is not +recognized: + +@example +type t = (a) .. b; +@end example + +The parser can be turned into a @acronym{GLR} parser, while also telling Bison +to be silent about the one known reduce/reduce conflict, by +adding these two declarations to the Bison input file (before the first +@samp{%%}): + +@example +%glr-parser +%expect-rr 1 +@end example + +@noindent +No change in the grammar itself is required. Now the +parser recognizes all valid declarations, according to the +limited syntax above, transparently. In fact, the user does not even +notice when the parser splits. + +So here we have a case where we can use the benefits of @acronym{GLR}, +almost without disadvantages. Even in simple cases like this, however, +there are at least two potential problems to beware. First, always +analyze the conflicts reported by Bison to make sure that @acronym{GLR} +splitting is only done where it is intended. A @acronym{GLR} parser +splitting inadvertently may cause problems less obvious than an +@acronym{LALR} parser statically choosing the wrong alternative in a +conflict. Second, consider interactions with the lexer (@pxref{Semantic +Tokens}) with great care. Since a split parser consumes tokens without +performing any actions during the split, the lexer cannot obtain +information via parser actions. Some cases of lexer interactions can be +eliminated by using @acronym{GLR} to shift the complications from the +lexer to the parser. You must check the remaining cases for +correctness. + +In our example, it would be safe for the lexer to return tokens based on +their current meanings in some symbol table, because no new symbols are +defined in the middle of a type declaration. Though it is possible for +a parser to define the enumeration constants as they are parsed, before +the type declaration is completed, it actually makes no difference since +they cannot be used within the same enumerated type declaration. + +@node Merging GLR Parses +@subsection Using @acronym{GLR} to Resolve Ambiguities +@cindex @acronym{GLR} parsing, ambiguous grammars +@cindex generalized @acronym{LR} (@acronym{GLR}) parsing, ambiguous grammars +@findex %dprec +@findex %merge +@cindex conflicts +@cindex reduce/reduce conflicts + +Let's consider an example, vastly simplified from a C++ grammar. + +@example +%@{ + #include + #define YYSTYPE char const * + int yylex (void); + void yyerror (char const *); +%@} + +%token TYPENAME ID + +%right '=' +%left '+' + +%glr-parser + +%% + +prog : + | prog stmt @{ printf ("\n"); @} + ; + +stmt : expr ';' %dprec 1 + | decl %dprec 2 + ; + +expr : ID @{ printf ("%s ", $$); @} + | TYPENAME '(' expr ')' + @{ printf ("%s ", $1); @} + | expr '+' expr @{ printf ("+ "); @} + | expr '=' expr @{ printf ("= "); @} + ; + +decl : TYPENAME declarator ';' + @{ printf ("%s ", $1); @} + | TYPENAME declarator '=' expr ';' + @{ printf ("%s ", $1); @} + ; + +declarator : ID @{ printf ("\"%s\" ", $1); @} + | '(' declarator ')' + ; +@end example + +@noindent +This models a problematic part of the C++ grammar---the ambiguity between +certain declarations and statements.

Since this is a +@acronym{GLR} parser, it therefore splits the problem into two parses, one for +each choice of resolving the reduce/reduce conflict. +Unlike the example from the previous section (@pxref{Simple GLR Parsers}), +however, neither of these parses ``dies,'' because the grammar as it stands is +ambiguous. One of the parsers eventually reduces @code{stmt : expr ';'} and +the other reduces @code{stmt : decl}, after which both parsers are in an +identical state: they've seen @samp{prog stmt} and have the same unprocessed +input remaining. We say that these parses have @dfn{merged.} + +At this point, the @acronym{GLR} parser requires a specification in the +grammar of how to choose between the competing parses. +In the example above, the two @code{%dprec} +declarations specify that Bison is to give precedence +to the parse that interprets the example as a +@code{decl}, which implies that @code{x} is a declarator. +The parser therefore prints + +@example +"x" y z + T +@end example + +The @code{%dprec} declarations only come into play when more than one +parse survives.

To achieve this, one must be able to keep track of +the @dfn{textual location}, or @dfn{location}, of each syntactic construct. +Bison provides a mechanism for handling these locations. + +Each token has a semantic value. In a similar fashion, each token has an +associated location, but the type of locations is the same for all tokens and +groupings. Moreover, the output parser is equipped with a default data +structure for storing locations (@pxref{Locations}, for more details). + +Like semantic values, locations can be reached in actions using a dedicated +set of constructs. In the example above, the location of the whole grouping +is @code{@@$}, while the locations of the subexpressions are @code{@@1} and +@code{@@3}. + +When a rule is matched, a default action is used to compute the semantic value +of its left hand side (@pxref{Actions}). In the same way, another default +action is used for locations. However, the action for locations is general +enough for most cases, meaning there is usually no need to describe for each +rule how @code{@@$} should be formed. When building a new location for a given +grouping, the default behavior of the output parser is to take the beginning +of the first symbol, and the end of the last symbol. + +@node Bison Parser +@section Bison Output: the Parser File +@cindex Bison parser +@cindex Bison utility +@cindex lexical analyzer, purpose +@cindex parser + +When you run Bison, you give it a Bison grammar file as input. The output +is a C source file that parses the language described by the grammar. +This file is called a @dfn{Bison parser}. Keep in mind that the Bison +utility and the Bison parser are two distinct programs: the Bison utility +is a program whose output is the Bison parser that becomes part of your +program. + +The job of the Bison parser is to group tokens into groupings according to +the grammar rules---for example, to build identifiers and operators into +expressions. As it does this, it runs the actions for the grammar rules it +uses. + +The tokens come from a function called the @dfn{lexical analyzer} that +you must supply in some fashion (such as by writing it in C). The Bison +parser calls the lexical analyzer each time it wants a new token. It +doesn't know what is ``inside'' the tokens (though their semantic values +may reflect this). Typically the lexical analyzer makes the tokens by +parsing characters of text, but Bison does not depend on this. +@xref{Lexical, ,The Lexical Analyzer Function @code{yylex}}. + +The Bison parser file is C code which defines a function named +@code{yyparse} which implements that grammar. This function does not make +a complete C program: you must supply some additional functions. One is +the lexical analyzer. Another is an error-reporting function which the +parser calls to report an error. In addition, a complete C program must +start with a function called @code{main}; you have to provide this, and +arrange for it to call @code{yyparse} or the parser will never run. +@xref{Interface, ,Parser C-Language Interface}. + +Aside from the token type names and the symbols in the actions you +write, all symbols defined in the Bison parser file itself +begin with @samp{yy} or @samp{YY}. This includes interface functions +such as the lexical analyzer function @code{yylex}, the error reporting +function @code{yyerror} and the parser function @code{yyparse} itself. +This also includes numerous identifiers used for internal purposes. +Therefore, you should avoid using C identifiers starting with @samp{yy} +or @samp{YY} in the Bison grammar file except for the ones defined in +this manual. Also, you should avoid using the C identifiers +@samp{malloc} and @samp{free} for anything other than their usual +meanings. + +In some cases the Bison parser file includes system headers, and in +those cases your code should respect the identifiers reserved by those +headers. On some non-@acronym{GNU} hosts, @code{}, @code{}, +@code{}, and @code{} are included as needed to +declare memory allocators and related types. @code{} is +included if message translation is in use +(@pxref{Internationalization}). Other system headers may +be included if you define @code{YYDEBUG} to a nonzero value +(@pxref{Tracing, ,Tracing Your Parser}). + +@node Stages +@section Stages in Using Bison +@cindex stages in using Bison +@cindex using Bison + +The actual language-design process using Bison, from grammar specification +to a working compiler or interpreter, has these parts: + +@enumerate +@item +Formally specify the grammar in a form recognized by Bison +(@pxref{Grammar File, ,Bison Grammar Files}).

The +Bison parser will use whatever type @code{YYSTYPE} is defined as; if you +don't define it, @code{int} is the default. Because we specify +@code{double}, each token and each expression has an associated value, +which is a floating point number. + +The @code{#include} directive is used to declare the exponentiation +function @code{pow}. + +The forward declarations for @code{yylex} and @code{yyerror} are +needed because the C language requires that functions be declared +before they are used. These functions will be defined in the +epilogue, but the parser calls them so they must be declared in the +prologue. + +The second section, Bison declarations, provides information to Bison +about the token types (@pxref{Bison Declarations, ,The Bison +Declarations Section}). Each terminal symbol that is not a +single-character literal must be declared here. (Single-character +literals normally don't need to be declared.) In this example, all the +arithmetic operators are designated by single-character literals, so the +only terminal symbol that needs to be declared is @code{NUM}, the token +type for numeric constants. + +@node Rpcalc Rules +@subsection Grammar Rules for @code{rpcalc} + +Here are the grammar rules for the reverse polish notation calculator. + +@example +input: /* empty */ + | input line +; + +line: '\n' + | exp '\n' @{ printf ("\t%.10g\n", $1); @} +; + +exp: NUM @{ $$ = $1; @} + | exp exp '+' @{ $$ = $1 + $2; @} + | exp exp '-' @{ $$ = $1 - $2; @} + | exp exp '*' @{ $$ = $1 * $2; @} + | exp exp '/' @{ $$ = $1 / $2; @} + /* Exponentiation */ + | exp exp '^' @{ $$ = pow ($1, $2); @} + /* Unary minus */ + | exp 'n' @{ $$ = -$1; @} +; +%% +@end example + +The groupings of the rpcalc ``language'' defined here are the expression +(given the name @code{exp}), the line of input (@code{line}), and the +complete input transcript (@code{input}). Each of these nonterminal +symbols has several alternate rules, joined by the vertical bar @samp{|} +which is read as ``or''. The following sections explain what these rules +mean. + +The semantics of the language is determined by the actions taken when a +grouping is recognized. The actions are the C code that appears inside +braces. @xref{Actions}. + +You must specify these actions in C, but Bison provides the means for +passing semantic values between the rules. In each action, the +pseudo-variable @code{$$} stands for the semantic value for the grouping +that the rule is going to construct. Assigning a value to @code{$$} is the +main job of most actions. The semantic values of the components of the +rule are referred to as @code{$1}, @code{$2}, and so on. + +@menu +* Rpcalc Input:: +* Rpcalc Line:: +* Rpcalc Expr:: +@end menu + +@node Rpcalc Input +@subsubsection Explanation of @code{input} + +Consider the definition of @code{input}: + +@example +input: /* empty */ + | input line +; +@end example + +This definition reads as follows: ``A complete input is either an empty +string, or a complete input followed by an input line''. Notice that +``complete input'' is defined in terms of itself. This definition is said +to be @dfn{left recursive} since @code{input} appears always as the +leftmost symbol in the sequence. @xref{Recursion, ,Recursive Rules}. + +The first alternative is empty because there are no symbols between the +colon and the first @samp{|}; this means that @code{input} can match an +empty string of input (no tokens). We write the rules this way because it +is legitimate to type @kbd{Ctrl-d} right after you start the calculator. +It's conventional to put an empty alternative first and write the comment +@samp{/* empty */} in it. + +The second alternate rule (@code{input line}) handles all nontrivial input. +It means, ``After reading any number of lines, read one more line if +possible.'' The left recursion makes this rule into a loop. Since the +first alternative matches empty input, the loop can be executed zero or +more times. + +The parser function @code{yyparse} continues to process input until a +grammatical error is seen or the lexical analyzer says there are no more +input tokens; we will arrange for the latter to happen at end-of-input. + +@node Rpcalc Line +@subsubsection Explanation of @code{line} + +Now consider the definition of @code{line}: + +@example +line: '\n' + | exp '\n' @{ printf ("\t%.10g\n", $1); @} +; +@end example + +The first alternative is a token which is a newline character; this means +that rpcalc accepts a blank line (and ignores it, since there is no +action). The second alternative is an expression followed by a newline. +This is the alternative that makes rpcalc useful. The semantic value of +the @code{exp} grouping is the value of @code{$1} because the @code{exp} in +question is the first symbol in the alternative. The action prints this +value, which is the result of the computation the user asked for. + +This action is unusual because it does not assign a value to @code{$$}. As +a consequence, the semantic value associated with the @code{line} is +uninitialized (its value will be unpredictable). This would be a bug if +that value were ever used, but we don't use it: once rpcalc has printed the +value of the user's input line, that value is no longer needed. + +@node Rpcalc Expr +@subsubsection Explanation of @code{expr} + +The @code{exp} grouping has several rules, one for each kind of expression. +The first rule handles the simplest expressions: those that are just numbers. +The second handles an addition-expression, which looks like two expressions +followed by a plus-sign. The third handles subtraction, and so on. + +@example +exp: NUM + | exp exp '+' @{ $$ = $1 + $2; @} + | exp exp '-' @{ $$ = $1 - $2; @} + @dots{} + ; +@end example + +We have used @samp{|} to join all the rules for @code{exp}, but we could +equally well have written them separately: + +@example +exp: NUM ; +exp: exp exp '+' @{ $$ = $1 + $2; @} ; +exp: exp exp '-' @{ $$ = $1 - $2; @} ; + @dots{} +@end example + +Most of the rules have actions that compute the value of the expression in +terms of the value of its parts. For example, in the rule for addition, +@code{$1} refers to the first component @code{exp} and @code{$2} refers to +the second one. The third component, @code{'+'}, has no meaningful +associated semantic value, but if it had one you could refer to it as +@code{$3}. When @code{yyparse} recognizes a sum expression using this +rule, the sum of the two subexpressions' values is produced as the value of +the entire expression. @xref{Actions}. + +You don't have to give an action for every rule. When a rule has no +action, Bison by default copies the value of @code{$1} into @code{$$}. +This is what happens in the first rule (the one that uses @code{NUM}). + +The formatting shown here is the recommended convention, but Bison does +not require it. You can add or change white space as much as you wish. +For example, this: + +@example +exp : NUM | exp exp '+' @{$$ = $1 + $2; @} | @dots{} ; +@end example + +@noindent +means the same thing as this: + +@example +exp: NUM + | exp exp '+' @{ $$ = $1 + $2; @} + | @dots{} +; +@end example + +@noindent +The latter, however, is much more readable. + +@node Rpcalc Lexer +@subsection The @code{rpcalc} Lexical Analyzer +@cindex writing a lexical analyzer +@cindex lexical analyzer, writing + +The lexical analyzer's job is low-level parsing: converting characters +or sequences of characters into tokens. The Bison parser gets its +tokens by calling the lexical analyzer. @xref{Lexical, ,The Lexical +Analyzer Function @code{yylex}}. + +Only a simple lexical analyzer is needed for the @acronym{RPN} +calculator. This +lexical analyzer skips blanks and tabs, then reads in numbers as +@code{double} and returns them as @code{NUM} tokens. Any other character +that isn't part of a number is a separate token. Note that the token-code +for such a single-character token is the character itself. + +The return value of the lexical analyzer function is a numeric code which +represents a token type. The same text used in Bison rules to stand for +this token type is also a C expression for the numeric code for the type. +This works in two ways. If the token type is a character literal, then its +numeric code is that of the character; you can use the same +character literal in the lexical analyzer to express the number. If the +token type is an identifier, that identifier is defined by Bison as a C +macro whose definition is the appropriate number. In this example, +therefore, @code{NUM} becomes a macro for @code{yylex} to use. + +The semantic value of the token (if it has one) is stored into the +global variable @code{yylval}, which is where the Bison parser will look +for it. (The C data type of @code{yylval} is @code{YYSTYPE}, which was +defined at the beginning of the grammar; @pxref{Rpcalc Declarations, +,Declarations for @code{rpcalc}}.) + +A token type code of zero is returned if the end-of-input is encountered. +(Bison recognizes any nonpositive value as indicating end-of-input.) + +Here is the code for the lexical analyzer: + +@example +@group +/* The lexical analyzer returns a double floating point + number on the stack and the token NUM, or the numeric code + of the character read if not a number.

Otherwise, @code{yyparse} returns nonzero. We +have not written any error rules in this example, so any invalid input will +cause the calculator program to exit. This is not clean behavior for a +real calculator, but it is adequate for the first example. + +@node Rpcalc Generate +@subsection Running Bison to Make the Parser +@cindex running Bison (introduction) + +Before running Bison to produce a parser, we need to decide how to +arrange all the source code in one or more source files. For such a +simple example, the easiest thing is to put everything in one file. The +definitions of @code{yylex}, @code{yyerror} and @code{main} go at the +end, in the epilogue of the file +(@pxref{Grammar Layout, ,The Overall Layout of a Bison Grammar}). + +For a large project, you would probably have several source files, and use +@code{make} to arrange to recompile them. + +With all the source in a single file, you use the following command to +convert it into a parser file: + +@example +bison @var{file}.y +@end example + +@noindent +In this example the file was called @file{rpcalc.y} (for ``Reverse Polish +@sc{calc}ulator'').

The declarations +@code{%left} and @code{%right} (right associativity) take the place of +@code{%token} which is used to declare a token type name without +associativity. (These tokens are single-character literals, which +ordinarily don't need to be declared. We declare them here to specify +the associativity.) + +Operator precedence is determined by the line ordering of the +declarations; the higher the line number of the declaration (lower on +the page or screen), the higher the precedence.

This means that an erroneous input line causes the +calculator program to exit. Now we show how to rectify this deficiency. + +The Bison language itself includes the reserved word @code{error}, which +may be included in the grammar rules.

If an expression that cannot be evaluated is +read, the error will be recognized by the third rule for @code{line}, +and parsing will continue. (The @code{yyerror} function is still called +upon to print its message as well.) The action executes the statement +@code{yyerrok}, a macro defined automatically by Bison; its meaning is +that error recovery is complete (@pxref{Error Recovery}). Note the +difference between @code{yyerrok} and @code{yyerror}; neither one is a +misprint. + +This form of error recovery deals with syntax errors. There are other +kinds of errors; for example, division by zero, which raises an exception +signal that is normally fatal. A real calculator program must handle this +signal and use @code{longjmp} to return to @code{main} and resume parsing +input lines; it would also have to discard the rest of the current line of +input.

Therefore, grammar rules for this example will be very close +to those of the previous example: we will only modify them to benefit +from the new information. + +Here, we will use locations to report divisions by zero, and locate the +wrong expressions or subexpressions. + +@example +@group +input : /* empty */ + | input line +; +@end group + +@group +line : '\n' + | exp '\n' @{ printf ("%d\n", $1); @} +; +@end group + +@group +exp : NUM @{ $$ = $1; @} + | exp '+' exp @{ $$ = $1 + $3; @} + | exp '-' exp @{ $$ = $1 - $3; @} + | exp '*' exp @{ $$ = $1 * $3; @} +@end group +@group + | exp '/' exp + @{ + if ($3) + $$ = $1 / $3; + else + @{ + $$ = 1; + fprintf (stderr, "%d.%d-%d.%d: division by zero", + @@3.first_line, @@3.first_column, + @@3.last_line, @@3.last_column); + @} + @} +@end group +@group + | '-' exp %prec NEG @{ $$ = -$2; @} + | exp '^' exp @{ $$ = pow ($1, $3); @} + | '(' exp ')' @{ $$ = $2; @} +@end group +@end example + +This code shows how to reach locations inside of semantic actions, by +using the pseudo-variables @code{@@@var{n}} for rule components, and the +pseudo-variable @code{@@$} for groupings. + +We don't need to assign a value to @code{@@$}: the output parser does it +automatically. By default, before executing the C code of each action, +@code{@@$} is set to range from the beginning of @code{@@1} to the end +of @code{@@@var{n}}, for a rule with @var{n} components. This behavior +can be redefined (@pxref{Location Default Action, , Default Action for +Locations}), and for very specific rules, @code{@@$} can be computed by +hand. + +@node Ltcalc Lexer +@subsection The @code{ltcalc} Lexical Analyzer. + +Until now, we relied on Bison's defaults to enable location +tracking. The next step is to rewrite the lexical analyzer, and make it +able to feed the parser with the token locations, as it already does for +semantic values. + +To this end, we must take into account every single character of the +input text, to avoid the computed locations of being fuzzy or wrong: + +@example +@group +int +yylex (void) +@{ + int c; +@end group + +@group + /* Skip white space. */ + while ((c = getchar ()) == ' ' || c == '\t') + ++yylloc.last_column; +@end group + +@group + /* Step. */ + yylloc.first_line = yylloc.last_line; + yylloc.first_column = yylloc.last_column; +@end group + +@group + /* Process numbers. */ + if (isdigit (c)) + @{ + yylval = c - '0'; + ++yylloc.last_column; + while (isdigit (c = getchar ())) + @{ + ++yylloc.last_column; + yylval = yylval * 10 + c - '0'; + @} + ungetc (c, stdin); + return NUM; + @} +@end group + + /* Return end-of-input. */ + if (c == EOF) + return 0; + + /* Return a single char, and update location. */ + if (c == '\n') + @{ + ++yylloc.last_line; + yylloc.last_column = 0; + @} + else + ++yylloc.last_column; + return c; +@} +@end example + +Basically, the lexical analyzer performs the same processing as before: +it skips blanks and tabs, and reads numbers or single-character tokens. +In addition, it updates @code{yylloc}, the global variable (of type +@code{YYLTYPE}) containing the token's location. + +Now, each time this function returns a token, the parser has its number +as well as its semantic value, and its location in the text. The last +needed change is to initialize @code{yylloc}, for example in the +controlling function: + +@example +@group +int +main (void) +@{ + yylloc.first_line = yylloc.last_line = 1; + yylloc.first_column = yylloc.last_column = 0; + return yyparse (); +@} +@end group +@end example + +Remember that computing locations is not a matter of syntax.

For example, the +definitions of @code{yylex} and @code{yyerror} often go here.

You use the symbol in grammar +rules to mean that a token in that class is allowed. The symbol is +represented in the Bison parser by a numeric code, and the @code{yylex} +function returns a token type code to indicate what kind of token has +been read. You don't need to know what the code value is; you can use +the symbol to stand for it. + +A @dfn{nonterminal symbol} stands for a class of syntactically +equivalent groupings. The symbol name is used in writing grammar rules. +By convention, it should be all lower case. + +Symbol names can contain letters, digits (not at the beginning), +underscores and periods. Periods make sense only in nonterminals. + +There are three ways of writing terminal symbols in the grammar: + +@itemize @bullet +@item +A @dfn{named token type} is written with an identifier, like an +identifier in C@. By convention, it should be all upper case. Each +such name must be defined with a Bison declaration such as +@code{%token}. @xref{Token Decl, ,Token Type Names}. + +@item +@cindex character token +@cindex literal token +@cindex single-character literal +A @dfn{character token type} (or @dfn{literal character token}) is +written in the grammar using the same syntax used in C for character +constants; for example, @code{'+'} is a character token type. A +character token type doesn't need to be declared unless you need to +specify its semantic value data type (@pxref{Value Type, ,Data Types of +Semantic Values}), associativity, or precedence (@pxref{Precedence, +,Operator Precedence}). + +By convention, a character token type is used only to represent a +token that consists of that particular character. Thus, the token +type @code{'+'} is used to represent the character @samp{+} as a +token. Nothing enforces this convention, but if you depart from it, +your program will confuse other readers. + +All the usual escape sequences used in character literals in C can be +used in Bison as well, but you must not use the null character as a +character literal because its numeric code, zero, signifies +end-of-input (@pxref{Calling Convention, ,Calling Convention +for @code{yylex}}). Also, unlike standard C, trigraphs have no +special meaning in Bison character literals, nor is backslash-newline +allowed. + +@item +@cindex string token +@cindex literal string token +@cindex multicharacter literal +A @dfn{literal string token} is written like a C string constant; for +example, @code{"<="} is a literal string token. A literal string token +doesn't need to be declared unless you need to specify its semantic +value data type (@pxref{Value Type}), associativity, or precedence +(@pxref{Precedence}). + +You can associate the literal string token with a symbolic name as an +alias, using the @code{%token} declaration (@pxref{Token Decl, ,Token +Declarations}). If you don't do that, the lexical analyzer has to +retrieve the token number for the literal string token from the +@code{yytname} table (@pxref{Calling Convention}). + +@strong{Warning}: literal string tokens do not work in Yacc. + +By convention, a literal string token is used only to represent a token +that consists of that particular string. Thus, you should use the token +type @code{"<="} to represent the string @samp{<=} as a token. Bison +does not enforce this convention, but if you depart from it, people who +read your program will be confused. + +All the escape sequences used in string literals in C can be used in +Bison as well, except that you must not use a null character within a +string literal. Also, unlike Standard C, trigraphs have no special +meaning in Bison string literals, nor is backslash-newline allowed. A +literal string token must contain two or more characters; for a token +containing just one character, use a character token (see above). +@end itemize + +How you choose to write a terminal symbol has no effect on its +grammatical meaning. That depends only on where it appears in rules and +on when the parser function returns that symbol. + +The value returned by @code{yylex} is always one of the terminal +symbols, except that a zero or negative value signifies end-of-input. +Whichever way you write the token type in the grammar rules, you write +it the same way in the definition of @code{yylex}. The numeric code +for a character token type is simply the positive numeric code of the +character, so @code{yylex} can use the identical value to generate the +requisite code, though you may need to convert it to @code{unsigned +char} to avoid sign-extension on hosts where @code{char} is signed. +Each named token type becomes a C macro in +the parser file, so @code{yylex} can use the name to stand for the code. +(This is why periods don't make sense in terminal symbols.) +@xref{Calling Convention, ,Calling Convention for @code{yylex}}. + +If @code{yylex} is defined in a separate file, you need to arrange for the +token-type macro definitions to be available there. Use the @samp{-d} +option when you run Bison, so that it will write these macro definitions +into a separate header file @file{@var{name}.tab.h} which you can include +in the other source files that need it. @xref{Invocation, ,Invoking Bison}. + +If you want to write a grammar that is portable to any Standard C +host, you must use only nonnull character tokens taken from the basic +execution character set of Standard C@. This set consists of the ten +digits, the 52 lower- and upper-case English letters, and the +characters in the following C-language string: + +@example +"\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_@{|@}~" +@end example + +The @code{yylex} function and Bison must use a consistent character set +and encoding for character tokens. For example, if you run Bison in an +@acronym{ASCII} environment, but then compile and run the resulting +program in an environment that uses an incompatible character set like +@acronym{EBCDIC}, the resulting program may not work because the tables +generated by Bison will assume @acronym{ASCII} numeric values for +character tokens. It is standard practice for software distributions to +contain C source files that were generated by Bison in an +@acronym{ASCII} environment, so installers on platforms that are +incompatible with @acronym{ASCII} must rebuild those files before +compiling them. + +The symbol @code{error} is a terminal symbol reserved for error recovery +(@pxref{Error Recovery}); you shouldn't use it for any other purpose. +In particular, @code{yylex} should never return this value. The default +value of the error token is 256, unless you explicitly assigned 256 to +one of your tokens with a @code{%token} declaration. + +@node Rules +@section Syntax of Grammar Rules +@cindex rule syntax +@cindex grammar rule syntax +@cindex syntax of grammar rules + +A Bison grammar rule has the following general form: + +@example +@group +@var{result}: @var{components}@dots{} + ; +@end group +@end example + +@noindent +where @var{result} is the nonterminal symbol that this rule describes, +and @var{components} are various terminal and nonterminal symbols that +are put together by this rule (@pxref{Symbols}). + +For example, + +@example +@group +exp: exp '+' exp + ; +@end group +@end example + +@noindent +says that two groupings of type @code{exp}, with a @samp{+} token in between, +can be combined into a larger grouping of type @code{exp}. + +White space in rules is significant only to separate symbols. You can add +extra white space as you wish. + +Scattered among the components can be @var{actions} that determine +the semantics of the rule. An action looks like this: + +@example +@{@var{C statements}@} +@end example + +@noindent +@cindex braced code +This is an example of @dfn{braced code}, that is, C code surrounded by +braces, much like a compound statement in C@. Braced code can contain +any sequence of C tokens, so long as its braces are balanced. Bison +does not check the braced code for correctness directly; it merely +copies the code to the output file, where the C compiler can check it. + +Within braced code, the balanced-brace count is not affected by braces +within comments, string literals, or character constants, but it is +affected by the C digraphs @samp{<%} and @samp{%>} that represent +braces. At the top level braced code must be terminated by @samp{@}} +and not by a digraph. Bison does not look for trigraphs, so if braced +code uses trigraphs you should ensure that they do not affect the +nesting of braces or the boundaries of comments, string literals, or +character constants. + +Usually there is only one action and it follows the components. +@xref{Actions}. + +@findex | +Multiple rules for the same @var{result} can be written separately or can +be joined with the vertical-bar character @samp{|} as follows: + +@example +@group +@var{result}: @var{rule1-components}@dots{} + | @var{rule2-components}@dots{} + @dots{} + ; +@end group +@end example + +@noindent +They are still considered distinct rules even when joined in this way. + +If @var{components} in a rule is empty, it means that @var{result} can +match the empty string. For example, here is how to define a +comma-separated sequence of zero or more @code{exp} groupings: + +@example +@group +expseq: /* empty */ + | expseq1 + ; +@end group + +@group +expseq1: exp + | expseq1 ',' exp + ; +@end group +@end example + +@noindent +It is customary to write a comment @samp{/* empty */} in each rule +with no components. + +@node Recursion +@section Recursive Rules +@cindex recursive rule + +A rule is called @dfn{recursive} when its @var{result} nonterminal +appears also on its right hand side. Nearly all Bison grammars need to +use recursion, because that is the only way to define a sequence of any +number of a particular thing. Consider this recursive definition of a +comma-separated sequence of one or more expressions: + +@example +@group +expseq1: exp + | expseq1 ',' exp + ; +@end group +@end example + +@cindex left recursion +@cindex right recursion +@noindent +Since the recursive use of @code{expseq1} is the leftmost symbol in the +right hand side, we call this @dfn{left recursion}. By contrast, here +the same construct is defined using @dfn{right recursion}: + +@example +@group +expseq1: exp + | exp ',' expseq1 + ; +@end group +@end example + +@noindent +Any kind of sequence can be defined using either left recursion or right +recursion, but you should always use left recursion, because it can +parse a sequence of any number of elements with bounded stack space. +Right recursion uses up space on the Bison stack in proportion to the +number of elements in the sequence, because all the elements must be +shifted onto the stack before the rule can be applied even once. +@xref{Algorithm, ,The Bison Parser Algorithm}, for further explanation +of this. + +@cindex mutual recursion +@dfn{Indirect} or @dfn{mutual} recursion occurs when the result of the +rule does not appear directly on its right hand side, but does appear +in rules for other nonterminals which do appear on its right hand +side. + +For example: + +@example +@group +expr: primary + | primary '+' primary + ; +@end group + +@group +primary: constant + | '(' expr ')' + ; +@end group +@end example + +@noindent +defines two mutually-recursive nonterminals, since each refers to the +other. + +@node Semantics +@section Defining Language Semantics +@cindex defining language semantics +@cindex language semantics, defining + +The grammar rules for a language determine only the syntax.

This was true in the +@acronym{RPN} and infix calculator examples (@pxref{RPN Calc, ,Reverse Polish +Notation Calculator}). + +Bison normally uses the type @code{int} for semantic values if your +program uses the same data type for all language constructs. To +specify some other type, define @code{YYSTYPE} as a macro, like this: + +@example +#define YYSTYPE double +@end example + +@noindent +@code{YYSTYPE}'s replacement list should be a type name +that does not contain parentheses or square brackets. +This macro definition must go in the prologue of the grammar file +(@pxref{Grammar Outline, ,Outline of a Bison Grammar}). + +@node Multiple Types +@subsection More Than One Value Type + +In most programs, you will need different data types for different kinds +of tokens and groupings. For example, a numeric constant may need type +@code{int} or @code{long int}, while a string constant needs type +@code{char *}, and an identifier might need a pointer to an entry in the +symbol table. + +To use more than one data type for semantic values in one parser, Bison +requires you to do two things: + +@itemize @bullet +@item +Specify the entire collection of possible data types, either by using the +@code{%union} Bison declaration (@pxref{Union Decl, ,The Collection of +Value Types}), or by using a @code{typedef} or a @code{#define} to +define @code{YYSTYPE} to be a union type whose member names are +the type tags. + +@item +Choose one of those types for each symbol (terminal or nonterminal) for +which semantic values are used. This is done for tokens with the +@code{%token} Bison declaration (@pxref{Token Decl, ,Token Type Names}) +and for groupings with the @code{%type} Bison declaration (@pxref{Type +Decl, ,Nonterminal Symbols}). +@end itemize + +@node Actions +@subsection Actions +@cindex action +@vindex $$ +@vindex $@var{n} + +An action accompanies a syntactic rule and contains C code to be executed +each time an instance of that rule is recognized. The task of most actions +is to compute a semantic value for the grouping built by the rule from the +semantic values associated with tokens or smaller groupings. + +An action consists of braced code containing C statements, and can be +placed at any position in the rule; +it is executed at that position. Most rules have just one action at the +end of the rule, following all the components. Actions in the middle of +a rule are tricky and used only for special purposes (@pxref{Mid-Rule +Actions, ,Actions in Mid-Rule}). + +The C code in an action can refer to the semantic values of the components +matched by the rule with the construct @code{$@var{n}}, which stands for +the value of the @var{n}th component. The semantic value for the grouping +being constructed is @code{$$}. Bison translates both of these +constructs into expressions of the appropriate type when it copies the +actions into the parser file. @code{$$} is translated to a modifiable +lvalue, so it can be assigned to. + +Here is a typical example: + +@example +@group +exp: @dots{} + | exp '+' exp + @{ $$ = $1 + $3; @} +@end group +@end example + +@noindent +This rule constructs an @code{exp} from two smaller @code{exp} groupings +connected by a plus-sign token. In the action, @code{$1} and @code{$3} +refer to the semantic values of the two component @code{exp} groupings, +which are the first and third symbols on the right hand side of the rule. +The sum is stored into @code{$$} so that it becomes the semantic value of +the addition-expression just recognized by the rule. If there were a +useful semantic value associated with the @samp{+} token, it could be +referred to as @code{$2}. + +Note that the vertical-bar character @samp{|} is really a rule +separator, and actions are attached to a single rule. This is a +difference with tools like Flex, for which @samp{|} stands for either +``or'', or ``the same action as that of the next rule''. In the +following example, the action is triggered only when @samp{b} is found: + +@example +@group +a-or-b: 'a'|'b' @{ a_or_b_found = 1; @}; +@end group +@end example + +@cindex default action +If you don't specify an action for a rule, Bison supplies a default: +@w{@code{$$ = $1}.} Thus, the value of the first symbol in the rule +becomes the value of the whole rule. Of course, the default action is +valid only if the two data types match. There is no meaningful default +action for an empty rule; every empty rule must have an explicit action +unless the rule's value does not matter. + +@code{$@var{n}} with @var{n} zero or negative is allowed for reference +to tokens and groupings on the stack @emph{before} those that match the +current rule. This is a very risky practice, and to use it reliably +you must be certain of the context in which the rule is applied. Here +is a case in which you can use this reliably: + +@example +@group +foo: expr bar '+' expr @{ @dots{} @} + | expr bar '-' expr @{ @dots{} @} + ; +@end group + +@group +bar: /* empty */ + @{ previous_expr = $0; @} + ; +@end group +@end example + +As long as @code{bar} is used only in the fashion shown here, @code{$0} +always refers to the @code{expr} which precedes @code{bar} in the +definition of @code{foo}. + +@vindex yylval +It is also possible to access the semantic value of the lookahead token, if +any, from a semantic action. +This semantic value is stored in @code{yylval}. +@xref{Action Features, ,Special Features for Use in Actions}. + +@node Action Types +@subsection Data Types of Values in Actions +@cindex action data types +@cindex data types in actions + +If you have chosen a single data type for semantic values, the @code{$$} +and @code{$@var{n}} constructs always have that data type. + +If you have used @code{%union} to specify a variety of data types, then you +must declare a choice among these types for each terminal or nonterminal +symbol that can have a semantic value. Then each time you use @code{$$} or +@code{$@var{n}}, its data type is determined by which symbol it refers to +in the rule. In this example, + +@example +@group +exp: @dots{} + | exp '+' exp + @{ $$ = $1 + $3; @} +@end group +@end example + +@noindent +@code{$1} and @code{$3} refer to instances of @code{exp}, so they all +have the data type declared for the nonterminal symbol @code{exp}. If +@code{$2} were used, it would have the data type declared for the +terminal symbol @code{'+'}, whatever that might be. + +Alternatively, you can specify the data type when you refer to the value, +by inserting @samp{<@var{type}>} after the @samp{$} at the beginning of the +reference. For example, if you have defined types as shown here: + +@example +@group +%union @{ + int itype; + double dtype; +@} +@end group +@end example + +@noindent +then you can write @code{$1} to refer to the first subunit of the +rule as an integer, or @code{$1} to refer to it as a double. + +@node Mid-Rule Actions +@subsection Actions in Mid-Rule +@cindex actions in mid-rule +@cindex mid-rule actions + +Occasionally it is useful to put an action in the middle of a rule. +These actions are written just like usual end-of-rule actions, but they +are executed before the parser even recognizes the following components. + +A mid-rule action may refer to the components preceding it using +@code{$@var{n}}, but it may not refer to subsequent components because +it is run before they are parsed. + +The mid-rule action itself counts as one of the components of the rule. +This makes a difference when there is another action later in the same rule +(and usually there is another at the end): you have to count the actions +along with the symbols when working out which number @var{n} to use in +@code{$@var{n}}. + +The mid-rule action can also have a semantic value. The action can set +its value with an assignment to @code{$$}, and actions later in the rule +can refer to the value using @code{$@var{n}}. Since there is no symbol +to name the action, there is no way to declare a data type for the value +in advance, so you must use the @samp{$<@dots{}>@var{n}} construct to +specify a data type each time you refer to this value. + +There is no way to set the value of the entire rule with a mid-rule +action, because assignments to @code{$$} do not have that effect. The +only way to set the value for the entire rule is with an ordinary action +at the end of the rule. + +Here is an example from a hypothetical compiler, handling a @code{let} +statement that looks like @samp{let (@var{variable}) @var{statement}} and +serves to create a variable named @var{variable} temporarily for the +duration of @var{statement}. To parse this construct, we must put +@var{variable} into the symbol table while @var{statement} is parsed, then +remove it afterward. Here is how it is done: + +@example +@group +stmt: LET '(' var ')' + @{ $$ = push_context (); + declare_variable ($3); @} + stmt @{ $$ = $6; + pop_context ($5); @} +@end group +@end example + +@noindent +As soon as @samp{let (@var{variable})} has been recognized, the first +action is run. It saves a copy of the current semantic context (the +list of accessible variables) as its semantic value, using alternative +@code{context} in the data-type union. Then it calls +@code{declare_variable} to add the new variable to that list. Once the +first action is finished, the embedded statement @code{stmt} can be +parsed. Note that the mid-rule action is component number 5, so the +@samp{stmt} is component number 6. + +After the embedded statement is parsed, its semantic value becomes the +value of the entire @code{let}-statement. Then the semantic value from the +earlier action is used to restore the prior list of variables. This +removes the temporary @code{let}-variable from the list so that it won't +appear to exist while the rest of the program is parsed. + +@findex %destructor +@cindex discarded symbols, mid-rule actions +@cindex error recovery, mid-rule actions +In the above example, if the parser initiates error recovery (@pxref{Error +Recovery}) while parsing the tokens in the embedded statement @code{stmt}, +it might discard the previous semantic context @code{$5} without +restoring it. +Thus, @code{$5} needs a destructor (@pxref{Destructor Decl, , Freeing +Discarded Symbols}). +However, Bison currently provides no means to declare a destructor specific to +a particular mid-rule action's semantic value. + +One solution is to bury the mid-rule action inside a nonterminal symbol and to +declare a destructor for that symbol: + +@example +@group +%type let +%destructor @{ pop_context ($$); @} let + +%% + +stmt: let stmt + @{ $$ = $2; + pop_context ($1); @} + ; + +let: LET '(' var ')' + @{ $$ = push_context (); + declare_variable ($3); @} + ; + +@end group +@end example + +@noindent +Note that the action is now at the end of its rule. +Any mid-rule action can be converted to an end-of-rule action in this way, and +this is what Bison actually does to implement mid-rule actions. + +Taking action before a rule is completely recognized often leads to +conflicts since the parser must commit to a parse in order to execute the +action. For example, the following two rules, without mid-rule actions, +can coexist in a working parser because the parser can shift the open-brace +token and look at what follows before deciding whether there is a +declaration or not: + +@example +@group +compound: '@{' declarations statements '@}' + | '@{' statements '@}' + ; +@end group +@end example + +@noindent +But when we add a mid-rule action as follows, the rules become nonfunctional: + +@example +@group +compound: @{ prepare_for_local_variables (); @} + '@{' declarations statements '@}' +@end group +@group + | '@{' statements '@}' + ; +@end group +@end example + +@noindent +Now the parser is forced to decide whether to run the mid-rule action +when it has read no farther than the open-brace.

Bison will always report +reduce/reduce conflicts for these parsers. With @acronym{GLR} +parsers, however, both kinds of conflicts are routine; otherwise, +there would be no need to use @acronym{GLR} parsing. Therefore, it is +also possible to specify an expected number of reduce/reduce conflicts +in @acronym{GLR} parsers, using the declaration: + +@example +%expect-rr @var{n} +@end example + +In general, using @code{%expect} involves these steps: + +@itemize @bullet +@item +Compile your grammar without @code{%expect}.

Reentrancy is important whenever asynchronous execution is possible; +for example, a nonreentrant program may not be safe to call from a signal +handler. In systems with multiple threads of control, a nonreentrant +program must be called only within interlocks. + +Normally, Bison generates a parser which is not reentrant. This is +suitable for most uses, and it permits compatibility with Yacc. (The +standard Yacc interfaces are inherently nonreentrant, because they use +statically allocated variables for communication with @code{yylex}, +including @code{yylval} and @code{yylloc}.) + +Alternatively, you can generate a pure, reentrant parser. The Bison +declaration @code{%define api.pure} says that you want the parser to be +reentrant. It looks like this: + +@example +%define api.pure +@end example + +The result is that the communication variables @code{yylval} and +@code{yylloc} become local variables in @code{yyparse}, and a different +calling convention is used for the lexical analyzer function +@code{yylex}. @xref{Pure Calling, ,Calling Conventions for Pure +Parsers}, for the details of this.

It is acceptable for a pure push parser to have +many parser instances, of the same type of parser, in memory at the same time. +An impure push parser should only use one parser at a time. + +When a push parser is selected, Bison will generate some new symbols in +the generated parser. @code{yypstate} is a structure that the generated +parser uses to store the parser's state. @code{yypstate_new} is the +function that will create a new parser instance. @code{yypstate_delete} +will free the resources associated with the corresponding parser instance. +Finally, @code{yypush_parse} is the function that should be called whenever a +token is available to provide the parser. A trivial example +of using a pure push parser would look like this: + +@example +int status; +yypstate *ps = yypstate_new (); +do @{ + status = yypush_parse (ps, yylex (), NULL); +@} while (status == YYPUSH_MORE); +yypstate_delete (ps); +@end example + +If the user decided to use an impure push parser, a few things about +the generated parser will change. The @code{yychar} variable becomes +a global variable instead of a variable in the @code{yypush_parse} function. +For this reason, the signature of the @code{yypush_parse} function is +changed to remove the token as a parameter. A nonreentrant push parser +example would thus look like this: + +@example +extern int yychar; +int status; +yypstate *ps = yypstate_new (); +do @{ + yychar = yylex (); + status = yypush_parse (ps); +@} while (status == YYPUSH_MORE); +yypstate_delete (ps); +@end example + +That's it. Notice the next token is put into the global variable @code{yychar} +for use by the next invocation of the @code{yypush_parse} function. + +Bison also supports both the push parser interface along with the pull parser +interface in the same generated parser. In order to get this functionality, +you should replace the @code{%define api.push_pull "push"} declaration with the +@code{%define api.push_pull "both"} declaration. Doing this will create all of +the symbols mentioned earlier along with the two extra symbols, @code{yyparse} +and @code{yypull_parse}. @code{yyparse} can be used exactly as it normally +would be used. However, the user should note that it is implemented in the +generated parser by calling @code{yypull_parse}. +This makes the @code{yyparse} function that is generated with the +@code{%define api.push_pull "both"} declaration slower than the normal +@code{yyparse} function. If the user +calls the @code{yypull_parse} function it will parse the rest of the input +stream. It is possible to @code{yypush_parse} tokens to select a subgrammar +and then @code{yypull_parse} the rest of the input stream. If you would like +to switch back and forth between between parsing styles, you would have to +write your own @code{yypull_parse} function that knows when to quit looking +for input. An example of using the @code{yypull_parse} function would look +like this: + +@example +yypstate *ps = yypstate_new (); +yypull_parse (ps); /* Will call the lexer */ +yypstate_delete (ps); +@end example + +Adding the @code{%define api.pure} declaration does exactly the same thing to +the generated parser with @code{%define api.push_pull "both"} as it did for +@code{%define api.push_pull "push"}. + +@node Decl Summary +@subsection Bison Declaration Summary +@cindex Bison declaration summary +@cindex declaration summary +@cindex summary, Bison declaration + +Here is a summary of the

lr.keep_unreachable_states +@findex %define lr.keep_unreachable_states + +@itemize @bullet +@item Language(s): all + +@item Purpose: Requests that Bison allow unreachable parser states to remain in +the parser tables. +Bison considers a state to be unreachable if there exists no sequence of +transitions from the start state to that state. +A state can become unreachable during conflict resolution if Bison disables a +shift action leading to it from a predecessor state. +Keeping unreachable states is sometimes useful for analysis purposes, but they +are useless in the generated

warnings may actually be relevant to a parser table +analysis that wants to keep unreachable states, so this behavior will likely +remain in future Bison releases. + +@item While Bison is able to remove unreachable states, it is not guaranteed to +remove other kinds of useless states. +Specifically, when Bison disables reduce actions during conflict resolution, +some goto actions may become useless, and thus some additional states may +become useless. +If Bison were to compute which goto actions were useless and then disable those +actions, it could identify such states as unreachable and then remove those +states. +However, Bison does not compute which goto actions are useless. +@end itemize +@end itemize + +@item namespace +@findex %define namespace + +@itemize +@item Languages(s): C++ + +@item Purpose: Specifies the namespace for the parser class. +For example, if you specify: + +@smallexample +%define namespace "foo::bar" +@end smallexample + +Bison uses @code{foo::bar} verbatim in references such as: + +@smallexample +foo::bar::parser::semantic_type +@end smallexample + +However, to open a namespace, Bison removes any leading @code{::} and then +splits on any remaining occurrences: + +@smallexample +namespace foo @{ namespace bar @{ + class position; + class location; +@} @} +@end smallexample + +@item Accepted Values: Any absolute or relative C++ namespace reference without +a trailing @code{"::"}. +For example, @code{"foo"} or @code{"::foo::bar"}. + +@item Default Value: The value specified by @code{%name-prefix}, which defaults +to @code{yy}. +This usage of @code{%name-prefix} is for backward compatibility and can be +confusing since @code{%name-prefix} also specifies the textual prefix for the +lexical analyzer function. +Thus, if you specify @code{%name-prefix}, it is best to also specify +@code{%define namespace} so that @code{%name-prefix} @emph{only} affects the +lexical analyzer function. +For example, if you specify: + +@smallexample +%define namespace "foo" +%name-prefix "bar::" +@end smallexample + +The parser namespace is @code{foo} and @code{yylex} is referenced as +@code{bar::lex}. +@end itemize

as a macro or you have used a +@code{<@var{type}>} tag without using @code{%union}. +Therefore, if you are using a @code{%union} +(@pxref{Multiple Types, ,More Than One Value Type}) with components that +require other definitions, or if you have defined a @code{YYSTYPE} macro +or type definition +(@pxref{Value Type, ,Data Types of Semantic Values}), you need to +arrange for these definitions to be propagated to all modules, e.g., by +putting them in a prerequisite header that is included both by your +parser and by any other module that needs @code{YYSTYPE}. + +Unless your parser is pure,

The stack is called the @dfn{parser stack}. Pushing a +token is traditionally called @dfn{shifting}. + +For example, suppose the infix calculator has read @samp{1 + 5 *}, with a +@samp{3} to come. The stack will have four elements, one for each token +that was shifted. + +But the stack does not always have an element for each token read. When +the last @var{n} tokens and groupings shifted match the components of a +grammar rule, they can be combined according to that rule. This is called +@dfn{reduction}. Those tokens and groupings are replaced on the stack by a +single grouping whose symbol is the result (left hand side) of that rule. +Running the rule's action is part of the process of reduction, because this +is what computes the semantic value of the resulting grouping. + +For example, if the infix calculator's parser stack contains this: + +@example +1 + 5 * 3 +@end example + +@noindent +and the next input token is a newline character, then the last three +elements can be reduced to 15 via the rule: + +@example +expr: expr '*' expr; +@end example + +@noindent +Then the stack contains just these three elements: + +@example +1 + 15 +@end example + +@noindent +At this point, another reduction can be made, resulting in the single value +16. Then the newline token can be shifted. + +The parser tries, by shifts and reductions, to reduce the entire input down +to a single grouping whose symbol is the grammar's start-symbol +(@pxref{Language and Grammar, ,Languages and Context-Free Grammars}). + +This kind of parser is known in the literature as a bottom-up parser. + +@menu +* Lookahead:: Parser looks one token ahead when deciding what to do. +* Shift/Reduce:: Conflicts: when either shifting or reduction is valid. +* Precedence:: Operator precedence works by resolving conflicts. +* Contextual Precedence:: When an operator's precedence depends on context. +* Parser States:: The parser is a finite-state-machine with stack. +* Reduce/Reduce:: When two rules are applicable in the same situation. +* Mystery Conflicts:: Reduce/reduce conflicts that look unjustified. +* Generalized LR Parsing:: Parsing arbitrary context-free grammars. +* Memory Management:: What happens when memory is exhausted. How to avoid it. +@end menu + +@node Lookahead +@section Lookahead Tokens +@cindex lookahead token + +The Bison parser does @emph{not} always reduce immediately as soon as the +last @var{n} tokens and groupings match a rule. This is because such a +simple strategy is inadequate to handle most languages. Instead, when a +reduction is possible, the parser sometimes ``looks ahead'' at the next +token in order to decide what to do. + +When a token is read, it is not immediately shifted; first it becomes the +@dfn{lookahead token}, which is not on the stack. Now the parser can +perform one or more reductions of tokens and groupings on the stack, while +the lookahead token remains off to the side. When no more reductions +should take place, the lookahead token is shifted onto the stack. This +does not mean that all possible reductions have been done; depending on the +token type of the lookahead token, some rules may choose to delay their +application. + +Here is a simple case where lookahead is needed. These three rules define +expressions which contain binary addition operators and postfix unary +factorial operators (@samp{!}), and allow parentheses for grouping. + +@example +@group +expr: term '+' expr + | term + ; +@end group + +@group +term: '(' expr ')' + | term '!' + | NUMBER + ; +@end group +@end example + +Suppose that the tokens @w{@samp{1 + 2}} have been read and shifted; what +should be done? If the following token is @samp{)}, then the first three +tokens must be reduced to form an @code{expr}. This is the only valid +course, because shifting the @samp{)} would produce a sequence of symbols +@w{@code{term ')'}}, and no rule allows this. + +If the following token is @samp{!}, then it must be shifted immediately so +that @w{@samp{2 !}} can be reduced to make a @code{term}. If instead the +parser were to reduce before shifting, @w{@samp{1 + 2}} would become an +@code{expr}. It would then be impossible to shift the @samp{!} because +doing so would produce on the stack the sequence of symbols @code{expr +'!'}. No rule allows that sequence. + +@vindex yychar +@vindex yylval +@vindex yylloc +The lookahead token is stored in the variable @code{yychar}. +Its semantic value and location, if any, are stored in the variables +@code{yylval} and @code{yylloc}. +@xref{Action Features, ,Special Features for Use in Actions}. + +@node Shift/Reduce +@section Shift/Reduce Conflicts +@cindex conflicts +@cindex shift/reduce conflicts +@cindex dangling @code{else} +@cindex @code{else}, dangling + +Suppose we are parsing a language which has if-then and if-then-else +statements, with a pair of rules like this: + +@example +@group +if_stmt: + IF expr THEN stmt + | IF expr THEN stmt ELSE stmt + ; +@end group +@end example + +@noindent +Here we assume that @code{IF}, @code{THEN} and @code{ELSE} are +terminal symbols for specific keyword tokens. + +When the @code{ELSE} token is read and becomes the lookahead token, the +contents of the stack (assuming the input is valid) are just right for +reduction by the first rule. But it is also legitimate to shift the +@code{ELSE}, because that would lead to eventual reduction by the second +rule. + +This situation, where either a shift or a reduction would be valid, is +called a @dfn{shift/reduce conflict}. Bison is designed to resolve +these conflicts by choosing to shift, unless otherwise directed by +operator precedence declarations. To see the reason for this, let's +contrast it with the other alternative. + +Since the parser prefers to shift the @code{ELSE}, the result is to attach +the else-clause to the innermost if-statement, making these two inputs +equivalent: + +@example +if x then if y then win (); else lose; + +if x then do; if y then win (); else lose; end; +@end example + +But if the parser chose to reduce when possible rather than shift, the +result would be to attach the else-clause to the outermost if-statement, +making these two inputs equivalent: + +@example +if x then if y then win (); else lose; + +if x then do; if y then win (); end; else lose; +@end example + +The conflict exists because the grammar as written is ambiguous: either +parsing of the simple nested if-statement is legitimate. The established +convention is that these ambiguities are resolved by attaching the +else-clause to the innermost if-statement; this is what Bison accomplishes +by choosing to shift rather than reduce. (It would ideally be cleaner to +write an unambiguous grammar, but that is very hard to do in this case.) +This particular ambiguity was first encountered in the specifications of +Algol 60 and is called the ``dangling @code{else}'' ambiguity. + +To avoid warnings from Bison about predictable, legitimate shift/reduce +conflicts, use the @code{%expect @var{n}} declaration. There will be no +warning as long as the number of shift/reduce conflicts is exactly @var{n}. +@xref{Expect Decl, ,Suppressing Conflict Warnings}. + +The definition of @code{if_stmt} above is solely to blame for the +conflict, but the conflict does not actually appear without additional +rules.

It +depends on the next token. Of course, if the next token is @samp{)}, we +must reduce; shifting is invalid because no single rule can reduce the +token sequence @w{@samp{- 2 )}} or anything starting with that. But if +the next token is @samp{*} or @samp{<}, we have a choice: either +shifting or reduction would allow the parse to complete, but with +different results. + +To decide which one Bison should do, we must consider the results. If +the next operator token @var{op} is shifted, then it must be reduced +first in order to permit another opportunity to reduce the difference. +The result is (in effect) @w{@samp{1 - (2 @var{op} 3)}}. On the other +hand, if the subtraction is reduced before shifting @var{op}, the result +is @w{@samp{(1 - 2) @var{op} 3}}. Clearly, then, the choice of shift or +reduce should depend on the relative precedence of the operators +@samp{-} and @var{op}: @samp{*} should be shifted first, but not +@samp{<}. + +@cindex associativity +What about input such as @w{@samp{1 - 2 - 5}}; should this be +@w{@samp{(1 - 2) - 5}} or should it be @w{@samp{1 - (2 - 5)}}?

The choice of left or right association is a +matter of whether the parser chooses to shift or reduce when the stack +contains @w{@samp{1 - 2}} and the lookahead token is @samp{-}: shifting +makes right-associativity. + +@node Using Precedence +@subsection Specifying Operator Precedence +@findex %left +@findex %right +@findex %nonassoc + +Bison allows you to specify these choices with the operator precedence +declarations @code{%left} and @code{%right}. Each such declaration +contains a list of tokens, which are operators whose precedence and +associativity is being declared. The @code{%left} declaration makes all +those operators left-associative and the @code{%right} declaration makes +them right-associative. A third alternative is @code{%nonassoc}, which +declares that it is a syntax error to find the same operator twice ``in a +row''. + +The relative precedence of different operators is controlled by the +order in which they are declared.

We assume that these tokens are more than one character long +and therefore are represented by names, not character literals.) + +@node How Precedence +@subsection How Precedence Works + +The first effect of the precedence declarations is to assign precedence +levels to the terminal symbols declared. The second effect is to assign +precedence levels to certain rules: each rule gets its precedence from +the last terminal symbol mentioned in the components. (You can also +specify explicitly the precedence of a rule. @xref{Contextual +Precedence, ,Context-Dependent Precedence}.) + +Finally, the resolution of conflicts works by comparing the precedence +of the rule being considered with that of the lookahead token. If the +token's precedence is higher, the choice is to shift. If the rule's +precedence is higher, the choice is to reduce. If they have equal +precedence, the choice is made based on the associativity of that +precedence level. The verbose output file made by @samp{-v} +(@pxref{Invocation, ,Invoking Bison}) says how each conflict was +resolved. + +Not all rules and not all tokens have precedence. If either the rule or +the lookahead token has no precedence, then the default is to shift. + +@node Contextual Precedence +@section Context-Dependent Precedence +@cindex context-dependent precedence +@cindex unary operator precedence +@cindex precedence, context-dependent +@cindex precedence, unary operator +@findex %prec + +Often the precedence of an operator depends on the context. This sounds +outlandish at first, but it is really very common. For example, a minus +sign typically has a very high precedence as a unary operator, and a +somewhat lower precedence (lower than multiplication) as a binary operator. + +The Bison precedence declarations, @code{%left}, @code{%right} and +@code{%nonassoc}, can only be used once for a given token; so a token has +only one precedence declared in this way. For context-dependent +precedence, you need to use an additional mechanism: the @code{%prec} +modifier for rules. + +The @code{%prec} modifier declares the precedence of a particular rule by +specifying a terminal symbol whose precedence should be used for that rule. +It's not necessary for that symbol to appear otherwise in the rule. The +modifier's syntax is: + +@example +%prec @var{terminal-symbol} +@end example + +@noindent +and it is written after the components of the rule. Its effect is to +assign the rule the precedence of @var{terminal-symbol}, overriding +the precedence that would be deduced for it in the ordinary way. The +altered rule precedence then affects how conflicts involving that rule +are resolved (@pxref{Precedence, ,Operator Precedence}). + +Here is how @code{%prec} solves the problem of unary minus. First, declare +a precedence for a fictitious terminal symbol named @code{UMINUS}. There +are no tokens of this type, but the symbol serves to stand for its +precedence: + +@example +@dots{} +%left '+' '-' +%left '*' +%left UMINUS +@end example + +Now the precedence of @code{UMINUS} can be used in specific rules: + +@example +@group +exp: @dots{} + | exp '-' exp + @dots{} + | '-' exp %prec UMINUS +@end group +@end example + +@ifset defaultprec +If you forget to append @code{%prec UMINUS} to the rule for unary +minus, Bison silently assumes that minus has its usual precedence. +This kind of problem can be tricky to debug, since one typically +discovers the mistake only by testing the code. + +The @code{%no-default-prec;} declaration makes it easier to discover +this kind of problem systematically. It causes rules that lack a +@code{%prec} modifier to have no precedence, even if the last terminal +symbol mentioned in their components has a declared precedence. + +If @code{%no-default-prec;} is in effect, you must specify @code{%prec} +for all rules that participate in precedence conflict resolution. +Then you will see any shift/reduce conflict until you tell Bison how +to resolve it, either by changing your grammar or by adding an +explicit precedence. This will probably add declarations to the +grammar, but it helps to protect against incorrect rule precedences. + +The effect of @code{%no-default-prec;} can be reversed by giving +@code{%default-prec;}, which is the default. +@end ifset + +@node Parser States +@section Parser States +@cindex finite-state machine +@cindex parser state +@cindex state (of parser) + +The function @code{yyparse} is implemented using a finite-state machine. +The values pushed on the parser stack are not simply token type codes; they +represent the entire sequence of terminal and nonterminal symbols at or +near the top of the stack. The current state collects all the information +about previous input which is relevant to deciding what to do next. + +Each time a lookahead token is read, the current parser state together +with the type of lookahead token are looked up in a table. This table +entry can say, ``Shift the lookahead token.'' In this case, it also +specifies the new parser state, which is pushed onto the top of the +parser stack. Or it can say, ``Reduce using rule number @var{n}.'' +This means that a certain number of tokens or groupings are taken off +the top of the stack, and replaced by one grouping. In other words, +that number of states are popped from the stack, and one new state is +pushed. + +There is one other alternative: the table can say that the lookahead token +is erroneous in the current state. This causes error processing to begin +(@pxref{Error Recovery}). + +@node Reduce/Reduce +@section Reduce/Reduce Conflicts +@cindex reduce/reduce conflict +@cindex conflicts, reduce/reduce + +A reduce/reduce conflict occurs if there are two or more rules that apply +to the same sequence of input.

It could be reduced to a +@code{maybeword} and then into a @code{sequence} via the second rule. +Alternatively, nothing-at-all could be reduced into a @code{sequence} +via the first rule, and this could be combined with the @code{word} +using the third rule for @code{sequence}. + +There is also more than one way to reduce nothing-at-all into a +@code{sequence}. This can be done directly via the first rule, +or indirectly via @code{maybeword} and then the second rule. + +You might think that this is a distinction without a difference, because it +does not change whether any particular input is valid or not. But it does +affect which actions are run. One parsing order runs the second rule's +action; the other runs the first rule's action and the third rule's action. +In this example, the output of the program changes. + +Bison resolves a reduce/reduce conflict by choosing to use the rule that +appears first in the grammar, but it is very risky to rely on this. Every +reduce/reduce conflict must be studied and usually eliminated. Here is the +proper way to define @code{sequence}: + +@example +sequence: /* empty */ + @{ printf ("empty sequence\n"); @} + | sequence word + @{ printf ("added word %s\n", $2); @} + ; +@end example + +Here is another common error that yields a reduce/reduce conflict: + +@example +sequence: /* empty */ + | sequence words + | sequence redirects + ; + +words: /* empty */ + | words word + ; + +redirects:/* empty */ + | redirects redirect + ; +@end example + +@noindent +The intention here is to define a sequence which can contain either +@code{word} or @code{redirect} groupings. The individual definitions of +@code{sequence}, @code{words} and @code{redirects} are error-free, but the +three together make a subtle ambiguity: even an empty input can be parsed +in infinitely many ways! + +Consider: nothing-at-all could be a @code{words}. Or it could be two +@code{words} in a row, or three, or any number. It could equally well be a +@code{redirects}, or two, or any number. Or it could be a @code{words} +followed by three @code{redirects} and another @code{words}. And so on. + +Here are two ways to correct these rules. First, to make it a single level +of sequence: + +@example +sequence: /* empty */ + | sequence word + | sequence redirect + ; +@end example + +Second, to prevent either a @code{words} or a @code{redirects} +from being empty: + +@example +sequence: /* empty */ + | sequence words + | sequence redirects + ; + +words: word + | words word + ; + +redirects:redirect + | redirects redirect + ; +@end example + +@node Mystery Conflicts +@section Mysterious Reduce/Reduce Conflicts + +Sometimes reduce/reduce conflicts can occur that don't look warranted. +Here is an example: + +@example +@group +%token ID + +%% +def: param_spec return_spec ',' + ; +param_spec: + type + | name_list ':' type + ; +@end group +@group +return_spec: + type + | name ':' type + ; +@end group +@group +type: ID + ; +@end group +@group +name: ID + ; +name_list: + name + | name ',' name_list + ; +@end group +@end example + +It would seem that this grammar can be parsed with only a single token +of lookahead: when a @code{param_spec} is being read, an @code{ID} is +a @code{name} if a comma or colon follows, or a @code{type} if another +@code{ID} follows. In other words, this grammar is @acronym{LR}(1). + +@cindex @acronym{LR}(1) +@cindex @acronym{LALR}(1) +However, Bison, like most parser generators, cannot actually handle all +@acronym{LR}(1) grammars. In this grammar, two contexts, that after +an @code{ID} +at the beginning of a @code{param_spec} and likewise at the beginning of +a @code{return_spec}, are similar enough that Bison assumes they are the +same. They appear similar because the same set of rules would be +active---the rule for reducing to a @code{name} and that for reducing to +a @code{type}. Bison is unable to determine at that stage of processing +that the rules would require different lookahead tokens in the two +contexts, so it makes a single parser state for them both. Combining +the two contexts causes a conflict later. In parser terminology, this +occurrence means that the grammar is not @acronym{LALR}(1). + +In general, it is better to fix deficiencies than to document them. But +this particular deficiency is intrinsically hard to fix; parser +generators that can handle @acronym{LR}(1) grammars are hard to write +and tend to +produce parsers that are very large. In practice, Bison is more useful +as it is now. + +When the problem arises, you can often fix it by identifying the two +parser states that are being confused, and adding something to make them +look distinct. In the above example, adding one rule to +@code{return_spec} as follows makes the problem go away: + +@example +@group +%token BOGUS +@dots{} +%% +@dots{} +return_spec: + type + | name ':' type + /* This rule is never used. */ + | ID BOGUS + ; +@end group +@end example + +This corrects the problem because it introduces the possibility of an +additional active rule in the context after the @code{ID} at the beginning of +@code{return_spec}. This rule is not active in the corresponding context +in a @code{param_spec}, so the two contexts receive distinct parser states. +As long as the token @code{BOGUS} is never generated by @code{yylex}, +the added rule cannot alter the way actual input is parsed. + +In this particular example, there is another way to solve the problem: +rewrite the rule for @code{return_spec} to use @code{ID} directly +instead of via @code{name}. This also causes the two confusing +contexts to have different sets of active rules, because the one for +@code{return_spec} activates the altered rule for @code{return_spec} +rather than the one for @code{name}. + +@example +param_spec: + type + | name_list ':' type + ; +return_spec: + type + | ID ':' type + ; +@end example + +For a more detailed exposition of @acronym{LALR}(1) parsers and parser +generators, please see: +Frank DeRemer and Thomas Pennello, Efficient Computation of +@acronym{LALR}(1) Look-Ahead Sets, @cite{@acronym{ACM} Transactions on +Programming Languages and Systems}, Vol.@: 4, No.@: 4 (October 1982), +pp.@: 615--649 @uref{http://doi.acm.org/10.1145/69622.357187}. + +@node Generalized LR Parsing +@section Generalized @acronym{LR} (@acronym{GLR}) Parsing +@cindex @acronym{GLR} parsing +@cindex generalized @acronym{LR} (@acronym{GLR}) parsing +@cindex ambiguous grammars +@cindex nondeterministic parsing + +Bison produces @emph{deterministic} parsers that choose uniquely +when to reduce and which reduction to apply +based on a summary of the preceding input and on one extra token of lookahead. +As a result, normal Bison handles a proper subset of the family of +context-free languages. +Ambiguous grammars, since they have strings with more than one possible +sequence of reductions cannot have deterministic parsers in this sense. +The same is true of languages that require more than one symbol of +lookahead, since the parser lacks the information necessary to make a +decision at the point it must be made in a shift-reduce parser. +Finally, as previously mentioned (@pxref{Mystery Conflicts}), +there are languages where Bison's particular choice of how to +summarize the input seen so far loses necessary information. + +When you use the @samp{%glr-parser} declaration in your grammar file, +Bison generates a parser that uses a different algorithm, called +Generalized @acronym{LR} (or @acronym{GLR}). A Bison @acronym{GLR} +parser uses the same basic +algorithm for parsing as an ordinary Bison parser, but behaves +differently in cases where there is a shift-reduce conflict that has not +been resolved by precedence rules (@pxref{Precedence}) or a +reduce-reduce conflict. When a @acronym{GLR} parser encounters such a +situation, it +effectively @emph{splits} into a several parsers, one for each possible +shift or reduction. These parsers then proceed as usual, consuming +tokens in lock-step. Some of the stacks may encounter other conflicts +and split further, with the result that instead of a sequence of states, +a Bison @acronym{GLR} parsing stack is what is in effect a tree of states. + +In effect, each stack represents a guess as to what the proper parse +is. Additional input may indicate that a guess was wrong, in which case +the appropriate stack silently disappears. Otherwise, the semantics +actions generated in each stack are saved, rather than being executed +immediately. When a stack disappears, its saved semantic actions never +get executed. When a reduction causes two stacks to become equivalent, +their sets of semantic actions are both saved with the state that +results from the reduction. We say that two stacks are equivalent +when they both represent the same sequence of states, +and each pair of corresponding states represents a +grammar symbol that produces the same segment of the input token +stream. + +Whenever the parser makes a transition from having multiple +states to having one, it reverts to the normal @acronym{LALR}(1) parsing +algorithm, after resolving and executing the saved-up actions. +At this transition, some of the states on the stack will have semantic +values that are sets (actually multisets) of possible actions. The +parser tries to pick one of the actions by first finding one whose rule +has the highest dynamic precedence, as set by the @samp{%dprec} +declaration. Otherwise, if the alternative actions are not ordered by +precedence, but there the same merging function is declared for both +rules by the @samp{%merge} declaration, +Bison resolves and evaluates both and then calls the merge function on +the result. Otherwise, it reports an ambiguity. + +It is possible to use a data structure for the @acronym{GLR} parsing tree that +permits the processing of any @acronym{LALR}(1) grammar in linear time (in the +size of the input), any unambiguous (not necessarily +@acronym{LALR}(1)) grammar in +quadratic worst-case time, and any general (possibly ambiguous) +context-free grammar in cubic worst-case time. However, Bison currently +uses a simpler data structure that requires time proportional to the +length of the input times the maximum number of stacks required for any +prefix of the input. Thus, really ambiguous or nondeterministic +grammars can require exponential time and space to process. Such badly +behaving examples, however, are not generally of practical interest. +Usually, nondeterminism in a grammar is local---the parser is ``in +doubt'' only for a few tokens at a time. Therefore, the current data +structure should generally be adequate. On @acronym{LALR}(1) portions of a +grammar, in particular, it is only slightly slower than with the default +Bison parser. + +For a more detailed exposition of @acronym{GLR} parsers, please see: Elizabeth +Scott, Adrian Johnstone and Shamsa Sadaf Hussain, Tomita-Style +Generalised @acronym{LR} Parsers, Royal Holloway, University of +London, Department of Computer Science, TR-00-12, +@uref{http://www.cs.rhul.ac.uk/research/languages/publications/tomita_style_1.ps}, +(2000-12-24). + +@node Memory Management +@section Memory Management, and How to Avoid Memory Exhaustion +@cindex memory exhaustion +@cindex memory management +@cindex stack overflow +@cindex parser stack overflow +@cindex overflow of parser stack + +The Bison parser stack can run out of memory if too many tokens are shifted and +not reduced.

The Bison maintainers hope to fix +this deficiency in a future release. + +@node Error Recovery +@chapter Error Recovery +@cindex error recovery +@cindex recovery from errors + +It is not usually acceptable to have a program terminate on a syntax +error. For example, a compiler should recover sufficiently to parse the +rest of the input file and check it for errors; a calculator should accept +another expression. + +In a simple interactive command parser where each input is one line, it may +be sufficient to allow @code{yyparse} to return 1 on error and have the +caller ignore the rest of the input line when that happens (and then call +@code{yyparse} again). But this is inadequate for a compiler, because it +forgets all the syntactic context leading up to the error. A syntax error +deep within a function in the compiler input should not cause the compiler +to treat the following line like the beginning of a source file. + +@findex error +You can define how to recover from a syntax error by writing rules to +recognize the special token @code{error}. This is a terminal symbol that +is always defined (you need not declare it) and reserved for error +handling. The Bison parser generates an @code{error} token whenever a +syntax error happens; if you have provided a rule to recognize this token +in the current context, the parse can continue. + +For example: + +@example +stmnts: /* empty string */ + | stmnts '\n' + | stmnts exp '\n' + | stmnts error '\n' +@end example + +The fourth rule in this example says that an error followed by a newline +makes a valid addition to any @code{stmnts}. + +What happens if a syntax error occurs in the middle of an @code{exp}? The +error recovery rule, interpreted strictly, applies to the precise sequence +of a @code{stmnts}, an @code{error} and a newline. If an error occurs in +the middle of an @code{exp}, there will probably be some additional tokens +and subexpressions on the stack after the last @code{stmnts}, and there +will be tokens to read before the next newline. So the rule is not +applicable in the ordinary way. + +But Bison can force the situation to fit the rule, by discarding part of +the semantic context and part of the input. First it discards states +and objects from the stack until it gets back to a state in which the +@code{error} token is acceptable. (This means that the subexpressions +already parsed are discarded, back to the last complete @code{stmnts}.) +At this point the @code{error} token can be shifted. Then, if the old +lookahead token is not acceptable to be shifted next, the parser reads +tokens and discards them until it finds a token which is acceptable. In +this example, Bison reads and discards input until the next newline so +that the fourth rule can apply. Note that discarded symbols are +possible sources of memory leaks, see @ref{Destructor Decl, , Freeing +Discarded Symbols}, for a means to reclaim this memory. + +The choice of error rules in the grammar is a choice of strategies for +error recovery. A simple and useful strategy is simply to skip the rest of +the current input line or current statement if an error is detected: + +@example +stmnt: error ';' /* On error, skip until ';' is read. */ +@end example + +It is also useful to recover to the matching close-delimiter of an +opening-delimiter that has already been parsed. Otherwise the +close-delimiter will probably appear to be unmatched, and generate another, +spurious error message: + +@example +primary: '(' expr ')' + | '(' error ')' + @dots{} + ; +@end example + +Error recovery strategies are necessarily guesses. When they guess wrong, +one syntax error often leads to another. In the above example, the error +recovery rule guesses that an error is due to bad input within one +@code{stmnt}. Suppose that instead a spurious semicolon is inserted in the +middle of a valid @code{stmnt}. After the error recovery rule recovers +from the first error, another syntax error will be found straightaway, +since the text following the spurious semicolon is also an invalid +@code{stmnt}. + +To prevent an outpouring of error messages, the parser will output no error +message for another syntax error that happens shortly after the first; only +after three consecutive input tokens have been successfully shifted will +error messages resume. + +Note that rules which accept the @code{error} token may have actions, just +as any other rules can. + +@findex yyerrok +You can make error messages resume immediately by using the macro +@code{yyerrok} in an action. If you do this in the error rule's action, no +error messages will be suppressed. This macro requires no arguments; +@samp{yyerrok;} is a valid C statement. + +@findex yyclearin +The previous lookahead token is reanalyzed immediately after an error. If +this is unacceptable, then the macro @code{yyclearin} may be used to clear +this token. Write the statement @samp{yyclearin;} in the error rule's +action. +@xref{Action Features, ,Special Features for Use in Actions}. + +For example, suppose that on a syntax error, an error handling routine is +called that advances the input stream to some point where parsing should +once again commence. The next symbol returned by the lexical scanner is +probably correct. The previous lookahead token ought to be discarded +with @samp{yyclearin;}. + +@vindex YYRECOVERING +The expression @code{YYRECOVERING ()} yields 1 when the parser +is recovering from a syntax error, and 0 otherwise. +Syntax error diagnostics are suppressed while recovering from a syntax +error. + +@node Context Dependency +@chapter Handling Context Dependencies + +The Bison paradigm is to parse tokens first, then group them into larger +syntactic units.

Although this violates the Bison paradigm, certain techniques +(known as @dfn{kludges}) may enable you to write Bison parsers for such +languages. + +@menu +* Semantic Tokens:: Token parsing can depend on the semantic context. +* Lexical Tie-ins:: Token parsing can depend on the syntactic context. +* Tie-in Recovery:: Lexical tie-ins have implications for how + error recovery rules must be written. +@end menu + +(Actually, ``kludge'' means any technique that gets its job done but is +neither clean nor robust.) + +@node Semantic Tokens +@section Semantic Info in Token Types + +The C language has a context dependency: the way an identifier is used +depends on what its current meaning is. For example, consider this: + +@example +foo (x); +@end example + +This looks like a function call statement, but if @code{foo} is a typedef +name, then this is actually a declaration of @code{x}. How can a Bison +parser for C decide how to parse this input? + +The method used in @acronym{GNU} C is to have two different token types, +@code{IDENTIFIER} and @code{TYPENAME}. When @code{yylex} finds an +identifier, it looks up the current declaration of the identifier in order +to decide which token type to return: @code{TYPENAME} if the identifier is +declared as a typedef, @code{IDENTIFIER} otherwise. + +The grammar rules can then express the context dependency by the choice of +token type to recognize. @code{IDENTIFIER} is accepted as an expression, +but @code{TYPENAME} is not. @code{TYPENAME} can start a declaration, but +@code{IDENTIFIER} cannot. In contexts where the meaning of the identifier +is @emph{not} significant, such as in declarations that can shadow a +typedef name, either @code{TYPENAME} or @code{IDENTIFIER} is +accepted---there is one rule for each of the two token types. + +This technique is simple to use if the decision of which kinds of +identifiers to allow is made at a place close to where the identifier is +parsed. But in C this is not always so: C allows a declaration to +redeclare a typedef name provided an explicit type has been specified +earlier: + +@example +typedef int foo, bar; +int baz (void) +@{ + static bar (bar); /* @r{redeclare @code{bar} as static variable} */ + extern foo foo (foo); /* @r{redeclare @code{foo} as function} */ + return foo (bar); +@} +@end example + +Unfortunately, the name being declared is separated from the declaration +construct itself by a complicated syntactic structure---the ``declarator''. + +As a result, part of the Bison parser for C needs to be duplicated, with +all the nonterminal names changed: once for parsing a declaration in +which a typedef name can be redefined, and once for parsing a +declaration in which that can't be done. Here is a part of the +duplication, with actions omitted for brevity: + +@example +initdcl: + declarator maybeasm '=' + init + | declarator maybeasm + ; + +notype_initdcl: + notype_declarator maybeasm '=' + init + | notype_declarator maybeasm + ; +@end example + +@noindent +Here @code{initdcl} can redeclare a typedef name, but @code{notype_initdcl} +cannot. The distinction between @code{declarator} and +@code{notype_declarator} is the same sort of thing. + +There is some similarity between this technique and a lexical tie-in +(described next), in that information which alters the lexical analysis is +changed during parsing by other parts of the program. The difference is +here the information is global, and is used for other purposes in the +program. A true lexical tie-in has a special-purpose flag controlled by +the syntactic context. + +@node Lexical Tie-ins +@section Lexical Tie-ins +@cindex lexical tie-in + +One way to handle context-dependency is the @dfn{lexical tie-in}: a flag +which is set by Bison actions, whose purpose is to alter the way tokens are +parsed. + +For example, suppose we have a language vaguely like C, but with a special +construct @samp{hex (@var{hex-expr})}. After the keyword @code{hex} comes +an expression in parentheses in which all integers are hexadecimal. In +particular, the token @samp{a1b} must be treated as an integer rather than +as an identifier if it appears in that context. Here is how you can do it: + +@example +@group +%@{ + int hexflag; + int yylex (void); + void yyerror (char const *); +%@} +%% +@dots{} +@end group +@group +expr: IDENTIFIER + | constant + | HEX '(' + @{ hexflag = 1; @} + expr ')' + @{ hexflag = 0; + $$ = $4; @} + | expr '+' expr + @{ $$ = make_sum ($1, $3); @} + @dots{} + ; +@end group + +@group +constant: + INTEGER + | STRING + ; +@end group +@end example + +@noindent +Here we assume that @code{yylex} looks at the value of @code{hexflag}; when +it is nonzero, all integers are parsed in hexadecimal, and tokens starting +with letters are parsed as integers if possible. + +The declaration of @code{hexflag} shown in the prologue of the parser file +is needed to make it accessible to the actions (@pxref{Prologue, ,The Prologue}). +You must also write the code in @code{yylex} to obey the flag. + +@node Tie-in Recovery +@section Lexical Tie-ins and Error Recovery + +Lexical tie-ins make strict demands on any error recovery rules you have. +@xref{Error Recovery}. + +The reason for this is that the purpose of an error recovery rule is to +abort the parsing of one construct and resume in some larger construct. +For example, in C-like languages, a typical error recovery rule is to skip +tokens until the next semicolon, and then start a new statement, like this: + +@example +stmt: expr ';' + | IF '(' expr ')' stmt @{ @dots{} @} + @dots{} + error ';' + @{ hexflag = 0; @} + ; +@end example + +If there is a syntax error in the middle of a @samp{hex (@var{expr})} +construct, this error rule will apply, and then the action for the +completed @samp{hex (@var{expr})} will never run. So @code{hexflag} would +remain set for the entire rest of the input, or until the next @code{hex} +keyword, causing identifiers to be misinterpreted as integers. + +To avoid this problem the error recovery rule itself clears @code{hexflag}. + +There may also be an error recovery rule that works within expressions. +For example, there could be a rule which applies within parentheses +and skips to the close-parenthesis: + +@example +@group +expr: @dots{} + | '(' expr ')' + @{ $$ = $2; @} + | '(' error ')' + @dots{} +@end group +@end example + +If this rule acts within the @code{hex} construct, it is not going to abort +that construct (since it applies to an inner level of parentheses within +the construct). Therefore, it should not clear the flag: the rest of +the @code{hex} construct should be parsed with the flag still in effect. + +What if there is an error recovery rule which might abort out of the +@code{hex} construct or might not, depending on circumstances? There is no +way you can write the action to determine whether a @code{hex} construct is +being aborted or not. So if you are using a lexical tie-in, you had better +make sure your error recovery rules are not of this kind. Each rule must +be such that you can be sure that it always will, or always won't, have to +clear the flag. + +@c ================================================== Debugging Your Parser + +@node Debugging +@chapter Debugging Your Parser + +Developing a parser can be a challenge, especially if you don't +understand the algorithm (@pxref{Algorithm, ,The Bison Parser +Algorithm}). Even so, sometimes a detailed description of the automaton +can help (@pxref{Understanding, , Understanding Your Parser}), or +tracing the execution of the parser can give some insight on why it +behaves improperly (@pxref{Tracing, , Tracing Your Parser}). + +@menu +* Understanding:: Understanding the structure of your parser. +* Tracing:: Tracing the execution of your parser. +@end menu + +@node Understanding +@section Understanding Your Parser + +As documented elsewhere (@pxref{Algorithm, ,The Bison Parser Algorithm}) +Bison parsers are @dfn{shift/reduce automata}. In some cases (much more +frequent than one would hope), looking at this automaton is required to +tune or simply fix a parser. Bison provides two different +representation of it, either textually or graphically (as a DOT file). + +The textual file is generated when the options @option{--report} or +@option{--verbose} are specified, see @xref{Invocation, , Invoking +Bison}. Its name is made by removing @samp{.tab.c} or @samp{.c} from +the parser output file name, and adding @samp{.output} instead. +Therefore, if the input file is @file{foo.y}, then the parser file is +called @file{foo.tab.c} by default.

If it was coming from +state 0, then, after this reduction it will return to state 0, and will +jump to state 2 (@samp{exp: go to state 2}). + +@example +state 2 + + $accept -> exp . $ (rule 0) + exp -> exp . '+' exp (rule 1) + exp -> exp . '-' exp (rule 2) + exp -> exp . '*' exp (rule 3) + exp -> exp .

For instance, +because of the item @samp{exp -> exp . '+' exp}, if the lookahead if +@samp{+}, it will be shifted on the parse stack, and the automaton +control will jump to state 4, corresponding to the item @samp{exp -> exp +'+' . exp}. Since there is no default action, any other token than +those listed above will trigger a syntax error. + +The state 3 is named the @dfn{final state}, or the @dfn{accepting +state}: + +@example +state 3 + + $accept -> exp $ .

The +conflict means that either the grammar is ambiguous, or the parser lacks +information to make the right decision. Indeed the grammar is +ambiguous, as, since we did not specify the precedence of @samp{/}, the +sentence @samp{NUM + NUM / NUM} can be parsed as @samp{NUM + (NUM / +NUM)}, which corresponds to shifting @samp{/}, or as @samp{(NUM + NUM) / +NUM}, which corresponds to reducing rule 1. + +Because in @acronym{LALR}(1) parsing a single decision can be made, Bison +arbitrarily chose to disable the reduction, see @ref{Shift/Reduce, , +Shift/Reduce Conflicts}. Discarded actions are reported in between +square brackets. + +Note that all the previous states had a single possible action: either +shifting the next token and going to the corresponding state, or +reducing a single rule. In the other cases, i.e., when shifting +@emph{and} reducing is possible or when @emph{several} reductions are +possible, the lookahead is required to select the action. State 8 is +one such state: if the lookahead is @samp{*} or @samp{/} then the action +is shifting, otherwise the action is reducing rule 1. In other words, +the first two items, corresponding to rule 1, are not eligible when the +lookahead token is @samp{*}, since we specified that @samp{*} has higher +precedence than @samp{+}. More generally, some items are eligible only +with some set of possible lookahead tokens. When run with +@option{--report=lookahead}, Bison specifies these lookahead tokens: + +@example +state 8 + + exp -> exp . '+' exp (rule 1) + exp -> exp '+' exp . [$, '+', '-', '/'] (rule 1) + exp -> exp . '-' exp (rule 2) + exp -> exp . '*' exp (rule 3) + exp -> exp .

This is compliant with @acronym{POSIX} Yacc.

Unless @acronym{POSIX} and Yacc portability matter to +you, this is +the preferred solution. +@end table + +We suggest that you always enable the debug option so that debugging is +always possible. + +The trace facility outputs messages with macro calls of the form +@code{YYFPRINTF (stderr, @var{format}, @var{args})} where +@var{format} and @var{args} are the usual @code{printf} format and variadic +arguments. If you define @code{YYDEBUG} to a nonzero value but do not +define @code{YYFPRINTF}, @code{} is automatically included +and @code{YYFPRINTF} is defined to @code{fprintf}. + +Once you have compiled the program with trace facilities, the way to +request a trace is to store a nonzero value in the variable @code{yydebug}. +You can do this by making the C code do it (in @code{main}, perhaps), or +you can alter the value with a C debugger. + +Each step taken by the parser when @code{yydebug} is nonzero produces a +line or two of trace information, written on @code{stderr}. The trace +messages tell you these things: + +@itemize @bullet +@item +Each time the parser calls @code{yylex}, what kind of token was read. + +@item +Each time a token is shifted, the depth and complete contents of the +state stack (@pxref{Parser States}). + +@item +Each time a rule is reduced, which rule it is, and the complete contents +of the state stack afterward. +@end itemize + +To make sense of this information, it helps to refer to the listing file +produced by the Bison @samp{-v} option (@pxref{Invocation, ,Invoking +Bison}). This file shows the meaning of each state in terms of +positions in various rules, and also what each state will do with each +possible input token. As you read the successive trace messages, you +can see that the parser is functioning according to its specification in +the listing file. Eventually you will arrive at the place where +something undesirable happens, and you will see which parts of the +grammar are to blame. + +The parser file is a C program and you can use C debuggers on it, but it's +not easy to interpret what it is doing. The parser function is a +finite-state machine interpreter, and aside from the actions it executes +the same code over and over. Only the values of variables show where in +the grammar it is working. + +@findex YYPRINT +The debugging information normally gives the token type of each token +read, but not its semantic value. You can optionally define a macro +named @code{YYPRINT} to provide a way to print the value. If you define +@code{YYPRINT}, it should take three arguments. The parser will pass a +standard I/O stream, the numeric code for the token type, and the token +value (from @code{yylval}). + +Here is an example of @code{YYPRINT} suitable for the multi-function +calculator (@pxref{Mfcalc Declarations, ,Declarations for @code{mfcalc}}): + +@smallexample +%@{ + static void print_token_value (FILE *, int, YYSTYPE); + #define YYPRINT(file, type, value) print_token_value (file, type, value) +%@} + +@dots{} %% @dots{} %% @dots{} + +static void +print_token_value (FILE *file, int type, YYSTYPE value) +@{ + if (type == VAR) + fprintf (file, "%s", value.tptr->name); + else if (type == NUM) + fprintf (file, "%d", value.val); +@} +@end smallexample + +@c ================================================= Invoking Bison + +@node Invocation +@chapter Invoking Bison +@cindex invoking Bison +@cindex Bison invocation +@cindex options for invoking Bison + +The usual way to invoke Bison is as follows: + +@example +bison @var{infile} +@end example + +Here @var{infile} is the grammar file name, which usually ends in +@samp{.y}. The parser file's name is made by replacing the @samp{.y} +with @samp{.tab.c} and removing any leading directory. Thus, the +@samp{bison foo.y} file name yields +@file{foo.tab.c}, and the @samp{bison hack/foo.y} file name yields +@file{foo.tab.c}. It's also possible, in case you are writing +C++ code instead of C in your grammar file, to name it @file{foo.ypp} +or @file{foo.y++}. Then, the output files will take an extension like +the given one as input (respectively @file{foo.tab.cpp} and +@file{foo.tab.c++}). +This feature takes effect with all options that manipulate file names like +@samp{-o} or @samp{-d}. + +For example : + +@example +bison -d @var{infile.yxx} +@end example +@noindent +will produce @file{infile.tab.cxx} and @file{infile.tab.hxx}, and + +@example +bison -d -o @var{output.c++} @var{infile.y} +@end example +@noindent +will produce @file{output.c++} and @file{outfile.h++}. + +For compatibility with @acronym{POSIX}, the standard Bison +distribution also contains a shell script called @command{yacc} that +invokes Bison with the @option{-y} option. + +@menu +* Bison Options:: All the options described in detail, + in alphabetical order by short options. +* Option Cross Key:: Alphabetical list of long options. +* Yacc Library:: Yacc-compatible @code{yylex} and @code{main}. +@end menu + +@node Bison Options +@section Bison Options + +Bison supports both traditional single-letter options and mnemonic long +option names.

This +section summarizes these differences. + +@itemize +@item +Java lacks a preprocessor, so the @code{YYERROR}, @code{YYACCEPT}, +@code{YYABORT} symbols (@pxref{Table of Symbols}) cannot obviously be +macros. Instead, they should be preceded by @code{return} when they +appear in an action. The actual definition of these symbols is +opaque to the Bison grammar, and it might change in the future. The +only meaningful operation that you can do, is to return them. +See @pxref{Java Action Features}. + +Note that of these three symbols, only @code{YYACCEPT} and +@code{YYABORT} will cause a return from the @code{yyparse} +method@footnote{Java parsers include the actions in a separate +method than @code{yyparse} in order to have an intuitive syntax that +corresponds to these C macros.}. + +@item +Java lacks unions, so @code{%union} has no effect. Instead, semantic +values have a common base type: @code{Object} or as specified by +@code{%define stype}. Angle backets on @code{%token}, @code{type}, +@code{$@var{n}} and @code{$$} specify subtypes rather than fields of +an union. The type of @code{$$}, even with angle brackets, is the base +type since Java casts are not allow on the left-hand side of assignments. +Also, @code{$@var{n}} and @code{@@@var{n}} are not allowed on the +left-hand side of assignments. See @pxref{Java Semantic Values} and +@pxref{Java Action Features}. + +@item +The prolog declarations have a different meaning than in C/C++ code. +@table @asis +@item @code{%code imports} +blocks are placed at the beginning of the Java source code. They may +include copyright notices. For a @code{package} declarations, it is +suggested to use @code{%define package} instead. + +@item unqualified @code{%code} +blocks are placed inside the parser class. + +@item @code{%code lexer} +blocks, if specified, should include the implementation of the +scanner.

What can I do? +@end display + +This question is already addressed elsewhere, @xref{Recursion, +,Recursive Rules}. + +@node How Can I Reset the Parser +@section How Can I Reset the Parser + +The following phenomenon has several symptoms, resulting in the +following typical questions: + +@display +I invoke @code{yyparse} several times, and on correct input it works +properly; but when a parse error is found, all the other calls fail +too. How can I reset the error flag of @code{yyparse}? +@end display + +@noindent +or + +@display +My parser includes support for an @samp{#include}-like feature, in +which case I run @code{yyparse} from @code{yyparse}. This fails +although I did specify @code{%define api.pure}. +@end display + +These problems typically come not from Bison itself, but from +Lex-generated scanners. Because these scanners use large buffers for +speed, they might not notice a change of input file. As a +demonstration, consider the following source file, +@file{first-line.l}: + +@verbatim +%{ +#include +#include +%} +%% +.*\n ECHO; return 1; +%% +int +yyparse (char const *file) +{ + yyin = fopen (file, "r"); + if (!yyin) + exit (2); + /* One token only. */ + yylex (); + if (fclose (yyin) != 0) + exit (3); + return 0; +} + +int +main (void) +{ + yyparse ("input"); + yyparse ("input"); + return 0; +} +@end verbatim + +@noindent +If the file @file{input} contains + +@verbatim +input:1: Hello, +input:2: World! +@end verbatim + +@noindent +then instead of getting the first line twice, you get: + +@example +$ @kbd{flex -ofirst-line.c first-line.l} +$ @kbd{gcc -ofirst-line first-line.c -ll} +$ @kbd{./first-line} +input:1: Hello, +input:2: World! +@end example + +Therefore, whenever you change @code{yyin}, you must tell the +Lex-generated scanner to discard its current buffer and switch to the +new one. This depends upon your implementation of Lex; see its +documentation for more. For Flex, it suffices to call +@samp{YY_FLUSH_BUFFER} after each change to @code{yyin}. If your +Flex-generated scanner needs to read from several input streams to +handle features like include files, you might consider using Flex +functions like @samp{yy_switch_to_buffer} that manipulate multiple +input buffers. + +If your Flex-generated scanner uses start conditions (@pxref{Start +conditions, , Start conditions, flex, The Flex Manual}), you might +also want to reset the scanner's state, i.e., go back to the initial +start condition, through a call to @samp{BEGIN (0)}. + +@node Strings are Destroyed +@section Strings are Destroyed + +@display +My parser seems to destroy old strings, or maybe it loses track of +them. Instead of reporting @samp{"foo", "bar"}, it reports +@samp{"bar", "bar"}, or even @samp{"foo\nbar", "bar"}. +@end display + +This error is probably the single most frequent ``bug report'' sent to +Bison lists, but is only concerned with a misunderstanding of the role +of the scanner.

The grammar file should also be +complete (i.e., I should be able to run it through Bison without having +to edit or add anything). The smaller and simpler the grammar, the +easier it will be to fix the bug. + +Include information about your compilation environment, including your +operating system's name and version and your compiler's name and +version. If you have trouble compiling, you should also include a +transcript of the build session, starting with the invocation of +`configure'. Depending on the nature of the bug, you may be asked to +send additional files as well (such as `config.h' or `config.cache'). + +Patches are most welcome, but not required.

It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +@sc{ascii} without markup, Texinfo input format, La@TeX{} input +format, @acronym{SGML} or @acronym{XML} using a publicly available +@acronym{DTD}, and standard-conforming simple @acronym{HTML}, +PostScript or @acronym{PDF} designed for human modification. Examples +of transparent image formats include @acronym{PNG}, @acronym{XCF} and +@acronym{JPG}. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, @acronym{SGML} or +@acronym{XML} for which the @acronym{DTD} and/or processing tools are +not generally available, and the machine-generated @acronym{HTML}, +PostScript or @acronym{PDF} produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation.

Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + +To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you +have certain responsibilities if you distribute copies of the +software, or if you modify it: responsibilities to respect the freedom +of others. + +For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, +receive or can get the source code. And you must show them these +terms so they know their rights. + +Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + +For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + +Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the +manufacturer can do so. This is fundamentally incompatible with the +aim of protecting users' freedom to change the software. The +systematic pattern of such abuse occurs in the area of products for +individuals to use, which is precisely where it is most unacceptable. +Therefore, we have designed this version of the GPL to prohibit the +practice for those products. If such problems arise substantially in +other domains, we stand ready to extend this provision to those +domains in future versions of the GPL, as needed to protect the +freedom of users. + +Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish +to avoid the special danger that patents applied to a free program +could make it effectively proprietary. To prevent this, the GPL +assures that patents cannot be used to render the program non-free. + +The precise terms and conditions for copying, distribution and +modification follow. + +@heading TERMS AND CONDITIONS + +@enumerate 0 +@item Definitions. + +``This License'' refers to version 3 of the GNU General Public License. + +``Copyright'' also means copyright-like laws that apply to other kinds +of works, such as semiconductor masks. + +``The Program'' refers to any copyrightable work licensed under this +License. Each licensee is addressed as ``you''. ``Licensees'' and +``recipients'' may be individuals or organizations. + +To ``modify'' a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of +an exact copy. The resulting work is called a ``modified version'' of +the earlier work or a work ``based on'' the earlier work. + +A ``covered work'' means either the unmodified Program or a work based +on the Program. + +To ``propagate'' a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + +To ``convey'' a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user +through a computer network, with no transfer of a copy, is not +conveying. + +An interactive user interface displays ``Appropriate Legal Notices'' to +the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + +@item Source Code. + +The ``source code'' for a work means the preferred form of the work for +making modifications to it. ``Object code'' means any non-source form +of a work. + +A ``Standard Interface'' means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + +The ``System Libraries'' of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +``Major Component'', in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + +The ``Corresponding Source'' for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + +The Corresponding Source need not include anything that users can +regenerate automatically from other parts of the Corresponding Source. + +The Corresponding Source for a work in source code form is that same +work. + +@item Basic Permissions. + +All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + +You may make, run and propagate covered works that you do not convey, +without conditions so long as your license otherwise remains in force. +You may convey covered works to others for the sole purpose of having +them make modifications exclusively for you, or provide you with +facilities for running those works, provided that you comply with the +terms of this License in conveying all material for which you do not +control copyright. Those thus making or running the covered works for +you must do so exclusively on your behalf, under your direction and +control, on terms that prohibit them from making any copies of your +copyrighted material outside their relationship with you. + +Conveying under any other circumstances is permitted solely under the +conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + +@item Protecting Users' Legal Rights From Anti-Circumvention Law. + +No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + +When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such +circumvention is effected by exercising rights under this License with +respect to the covered work, and you disclaim any intention to limit +operation or modification of the work as a means of enforcing, against +the work's users, your or third parties' legal rights to forbid +circumvention of technological measures. + +@item Conveying Verbatim Copies. + +You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + +You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + +@item Conveying Modified Source Versions. + +You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these +conditions: + +@enumerate a +@item +The work must carry prominent notices stating that you modified it, +and giving a relevant date. + +@item +The work must carry prominent notices stating that it is released +under this License and any conditions added under section 7. This +requirement modifies the requirement in section 4 to ``keep intact all +notices''. + +@item +You must license the entire work, as a whole, under this License to +anyone who comes into possession of a copy. This License will +therefore apply, along with any applicable section 7 additional terms, +to the whole of the work, and all its parts, regardless of how they +are packaged. This License gives no permission to license the work in +any other way, but it does not invalidate such permission if you have +separately received it. + +@item +If the work has interactive user interfaces, each must display +Appropriate Legal Notices; however, if the Program has interactive +interfaces that do not display Appropriate Legal Notices, your work +need not make them do so. +@end enumerate + +A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +``aggregate'' if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + +@item Conveying Non-Source Forms. + +You may convey a covered work in object code form under the terms of +sections 4 and 5, provided that you also convey the machine-readable +Corresponding Source under the terms of this License, in one of these +ways: + +@enumerate a +@item +Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by the +Corresponding Source fixed on a durable physical medium customarily +used for software interchange. + +@item +Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by a written +offer, valid for at least three years and valid for as long as you +offer spare parts or customer support for that product model, to give +anyone who possesses the object code either (1) a copy of the +Corresponding Source for all the software in the product that is +covered by this License, on a durable physical medium customarily used +for software interchange, for a price no more than your reasonable +cost of physically performing this conveying of source, or (2) access +to copy the Corresponding Source from a network server at no charge. + +@item +Convey individual copies of the object code with a copy of the written +offer to provide the Corresponding Source. This alternative is +allowed only occasionally and noncommercially, and only if you +received the object code with such an offer, in accord with subsection +6b. + +@item +Convey the object code by offering access from a designated place +(gratis or for a charge), and offer equivalent access to the +Corresponding Source in the same way through the same place at no +further charge. You need not require recipients to copy the +Corresponding Source along with the object code. If the place to copy +the object code is a network server, the Corresponding Source may be +on a different server (operated by you or a third party) that supports +equivalent copying facilities, provided you maintain clear directions +next to the object code saying where to find the Corresponding Source. +Regardless of what server hosts the Corresponding Source, you remain +obligated to ensure that it is available for as long as needed to +satisfy these requirements. + +@item +Convey the object code using peer-to-peer transmission, provided you +inform other peers where the object code and Corresponding Source of +the work are being offered to the general public at no charge under +subsection 6d. + +@end enumerate + +A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + +A ``User Product'' is either (1) a ``consumer product'', which means any +tangible personal property which is normally used for personal, +family, or household purposes, or (2) anything designed or sold for +incorporation into a dwelling. In determining whether a product is a +consumer product, doubtful cases shall be resolved in favor of +coverage. For a particular product received by a particular user, +``normally used'' refers to a typical or common use of that class of +product, regardless of the status of the particular user or of the way +in which the particular user actually uses, or expects or is expected +to use, the product. A product is a consumer product regardless of +whether the product has substantial commercial, industrial or +non-consumer uses, unless such uses represent the only significant +mode of use of the product. + +``Installation Information'' for a User Product means any methods, +procedures, authorization keys, or other information required to +install and execute modified versions of a covered work in that User +Product from a modified version of its Corresponding Source. The +information must suffice to ensure that the continued functioning of +the modified object code is in no case prevented or interfered with +solely because modification has been made. + +If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + +The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or +updates for a work that has been modified or installed by the +recipient, or for the User Product in which it has been modified or +installed. Access to a network may be denied when the modification +itself materially and adversely affects the operation of the network +or violates the rules and protocols for communication across the +network. + +Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + +@item Additional Terms. + +``Additional permissions'' are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + +When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + +Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders +of that material) supplement the terms of this License with terms: + +@enumerate a +@item +Disclaiming warranty or limiting liability differently from the terms +of sections 15 and 16 of this License; or + +@item +Requiring preservation of specified reasonable legal notices or author +attributions in that material or in the Appropriate Legal Notices +displayed by works containing it; or + +@item +Prohibiting misrepresentation of the origin of that material, or +requiring that modified versions of such material be marked in +reasonable ways as different from the original version; or + +@item +Limiting the use for publicity purposes of names of licensors or +authors of the material; or + +@item +Declining to grant rights under trademark law for use of some trade +names, trademarks, or service marks; or + +@item +Requiring indemnification of licensors and authors of that material by +anyone who conveys the material (or modified versions of it) with +contractual assumptions of liability to the recipient, for any +liability that these contractual assumptions directly impose on those +licensors and authors. +@end enumerate + +All other non-permissive additional terms are considered ``further +restrictions'' within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + +If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + +Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; the +above requirements apply either way. + +@item Termination. + +You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + +@item Acceptance Not Required for Having Copies. + +You are not required to accept this License in order to receive or run +a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + +@item Automatic Licensing of Downstream Recipients. + +Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + +An ``entity transaction'' is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + +You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + +@item Patents. + +A ``contributor'' is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's ``contributor version''. + +A contributor's ``essential patent claims'' are all patent claims owned +or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, ``control'' includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + +Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + +In the following three paragraphs, a ``patent license'' is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To ``grant'' such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + +If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. ``Knowingly relying'' means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + +If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + +A patent license is ``discriminatory'' if it does not include within the +scope of its coverage, prohibits the exercise of, or is conditioned on +the non-exercise of one or more of the rights that are specifically +granted under this License. You may not convey a covered work if you +are a party to an arrangement with a third party that is in the +business of distributing software, under which you make payment to the +third party based on the extent of your activity of conveying the +work, and under which the third party grants, to any of the parties +who would receive the covered work from you, a discriminatory patent +license (a) in connection with copies of the covered work conveyed by +you (or copies made from those copies), or (b) primarily for and in +connection with specific products or compilations that contain the +covered work, unless you entered into that arrangement, or that patent +license was granted, prior to 28 March 2007. + +Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + +@item No Surrender of Others' Freedom. + +If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey +a covered work so as to satisfy simultaneously your obligations under +this License and any other pertinent obligations, then as a +consequence you may not convey it at all. For example, if you agree +to terms that obligate you to collect a royalty for further conveying +from those to whom you convey the Program, the only way you could +satisfy both those terms and this License would be to refrain entirely +from conveying the Program. + +@item Use with the GNU Affero General Public License. + +Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + +@item Revised Versions of this License. + +The Free Software Foundation may publish revised and/or new versions +of the GNU General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies that a certain numbered version of the GNU General Public +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that numbered version or +of any later version published by the Free Software Foundation. If +the Program does not specify a version number of the GNU General +Public License, you may choose any version ever published by the Free +Software Foundation. + +If the Program specifies that a proxy can decide which future versions +of the GNU General Public License can be used, that proxy's public +statement of acceptance of a version permanently authorizes you to +choose that version for the Program. + +Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + +@item Disclaimer of Warranty. + +THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT +WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND +PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE +DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR +CORRECTION. + +@item Limitation of Liability. + +IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR +CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES +ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT +NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR +LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM +TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER +PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +@item Interpretation of Sections 15 and 16. + +If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + +@end enumerate + +@heading END OF TERMS AND CONDITIONS + +@heading How to Apply These Terms to Your New Programs + +If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + +To do so, attach the following notices to the program.

The idea +is that you would use these pre-tested macros to solve a +very specific set of problems, and they would run fast. +Caution: no side-effects in arguments please!! They may be +evaluated MANY times!! + +These macros operate a stack of objects. Each object starts life +small, and may grow to maturity. (Consider building a word syllable +by syllable.) An object can move while it is growing. Once it has +been "finished" it never changes address again. So the "top of the +stack" is typically an immature growing object, while the rest of the +stack is of mature, fixed size and fixed address objects. + +These routines grab large chunks of memory, using a function you +supply, called `obstack_chunk_alloc'. On occasion, they free chunks, +by calling `obstack_chunk_free'. You must define them and declare +them before using any obstack macros. + +Each independent stack is represented by a `struct obstack'. +Each of the obstack macros expects a pointer to such a structure +as the first argument. + +One motivation for this package is the problem of growing char strings +in symbol tables. Unless you are "fascist pig with a read-only mind" +--Gosper's immortal quote from HAKMEM item 154, out of context--you +would not like to put any arbitrary upper limit on the length of your +symbols. + +In practice this often means you will build many short symbols and a +few long symbols. At the time you are reading a symbol you don't know +how long it is. One traditional method is to read a symbol into a +buffer, realloc()ating the buffer every time you try to read a symbol +that is longer than the buffer. This is beaut, but you still will +want to copy the symbol from the buffer to a more permanent +symbol-table entry say about half the time. + +With obstacks, you can work differently. Use one obstack for all symbol +names. As you read a symbol, grow the name in the obstack gradually. +When the name is complete, finalize it. Then, if the symbol exists already, +free the newly read name. + +The way we do this is to take a large chunk, allocating memory from +low addresses. When you want to build a symbol in the chunk you just +add chars above the current "high water mark" in the chunk. When you +have finished adding chars, because you got to the end of the symbol, +you know how long the chars are, and you can create a new object. +Mostly the chars will not burst over the highest address of the chunk, +because you would typically expect a chunk to be (say) 100 times as +long as an average object. + +In case that isn't clear, when we have enough chars to make up +the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) +so we just point to it where it lies. No moving of chars is +needed and this is the second win: potentially long strings need +never be explicitly shuffled. Once an object is formed, it does not +change its address during its lifetime. + +When the chars burst over a chunk boundary, we allocate a larger +chunk, and then copy the partly formed object from the end of the old +chunk to the beginning of the new larger chunk. We then carry on +accreting characters to the end of the object as we normally would. + +A special macro is provided to add a single char at a time to a +growing object. This allows the use of register variables, which +break the ordinary 'growth' macro. + +Summary: + We allocate large chunks. + We carve out one object at a time from the current chunk. + Once carved, an object never moves. + We are free to append data of any size to the currently + growing object. + Exactly one object is growing in an obstack at any one time. + You can run one obstack per control block. + You may have as many control blocks as you dare. + Because of the way we do it, you can `unwind' an obstack + back to a previous state.

To + be portable, R should be an integer constant expression. Unlike + assert (R), there is no run-time overhead. + + There are two macros, since no single macro can be used in all + contexts in C. verify_true (R) is for scalar contexts, including + integer constant expression contexts. verify (R) is for declaration + contexts, e.g., the top level. + + Symbols ending in "__" are private to this header. + + The code below uses several ideas. + + * The first step is ((R) ? 1 : -1). Given an expression R, of + integral or boolean or floating-point type, this yields an + expression of integral type, whose value is later verified to be + constant and nonnegative. + + * Next this expression W is wrapped in a type + struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }. + If W is negative, this yields a compile-time error. No compiler can + deal with a bit-field of negative size. + + One might think that an array size check would have the same + effect, that is, that the type struct { unsigned int dummy[W]; } + would work as well. However, inside a function, some compilers + (such as C++ compilers and GNU C) allow local parameters and + variables inside array size expressions. With these compilers, + an array size check would not properly diagnose this misuse of + the verify macro: + + void function (int n) { verify (n < 0); } + + * For the verify macro, the struct verify_type__ will need to + somehow be embedded into a declaration. To be portable, this + declaration must declare an object, a constant, a function, or a + typedef name. If the declared entity uses the type directly, + such as in + + struct dummy {...}; + typedef struct {...} dummy; + extern struct {...} *dummy; + extern void dummy (struct {...} *); + extern struct {...} *dummy (void); + + two uses of the verify macro would yield colliding declarations + if the entity names are not disambiguated. A workaround is to + attach the current line number to the entity name: + + #define GL_CONCAT0(x, y) x##y + #define GL_CONCAT(x, y) GL_CONCAT0 (x, y) + extern struct {...} * GL_CONCAT(dummy,__LINE__); + + But this has the problem that two invocations of verify from + within the same macro would collide, since the __LINE__ value + would be the same for both invocations. + + A solution is to use the sizeof operator. It yields a number, + getting rid of the identity of the type.

Bison is upwardly compatible with Yacc, so any +correctly written Yacc grammar should work with Bison without any +changes. If you know Yacc, you shouldn't have any trouble using +Bison.

It only contains two symbols: main and yyerror, +# and both of these are extremely simple (couple lines of C total). +# It doesn't really pay off to introduce a shared library for that. +# +# Therefore -devel subpackage could have been created as -static, but +# the split was done in Jan 2005, which predates current guidelines. +# Besides there is logic to that: the library is devel in the sense +# that the generated parser could be distributed together with other +# sources, and only bison-devel would be necessary to wrap the build. + +%prep +%setup -q + +%build +cp %{SOURCE1001} . +%configure --disable-nls +make + +%install +%makeinstall + +# Remove unpackaged files. +rm -f %{buildroot}/%{_bindir}/yacc +rm -f %{buildroot}/%{_mandir}/man1/yacc* +rm -rf %{buildroot}/%{_infodir} + + +# The distribution contains also source files.

More precisely Bison augments the grammar with the + initial rule, `$accept: START-SYMBOL $end', which is numbered 1, + all the user rules are 2, 3 etc. Each time a rule number is + presented to the user, we subtract 1, so *displayed* rule numbers + are 0, 1, 2... + + Internally, we cannot use the number 0 for a rule because for + instance RITEM stores both symbol (the RHS) and rule numbers: the + symbols are shorts >= 0, and rule number are stored negative. + Therefore 0 cannot be used, since it would be both the rule number + 0, and the token $end). + + Actions are accessed via the rule number. + + The rules themselves are described by several arrays: amongst which + RITEM, and RULES. + + RULES is an array of rules, whose members are: + + RULES[R].lhs -- the symbol of the left hand side of rule R. + + RULES[R].rhs -- the index in RITEM of the beginning of the portion + for rule R. + + RULES[R].prec -- the symbol providing the precedence level of R. + + RULES[R].precsym -- the symbol attached (via %prec) to give its + precedence to R. Of course, if set, it is equal to `prec', but we + need to distinguish one from the other when reducing: a symbol used + in a %prec is not useless. + + RULES[R].assoc -- the associativity of R. + + RULES[R].dprec -- the dynamic precedence level of R (for GLR + parsing). + + RULES[R].merger -- index of merging function for R (for GLR + parsing). + + RULES[R].line -- the line where R was defined. + + RULES[R].useful -- true iff the rule is used (i.e., false if thrown + away by reduce). + + The right hand side is stored as symbol numbers in a portion of + RITEM. + + The length of the portion is one greater than the number of symbols + in the rule's right hand side.

These symbols at these items are the allowable inputs that + can follow now. + + A core represents one state. States are numbered in the NUMBER + field. When generate_states is finished, the starting state is + state 0 and NSTATES is the number of states. (FIXME: This sentence + is no longer true: A transition to a state whose state number is + NSTATES indicates termination.) All the cores are chained together + and FIRST_STATE points to the first one (state 0). + + For each state there is a particular symbol which must have been + the last thing accepted to reach that state. It is the + ACCESSING_SYMBOL of the core. + + Each core contains a vector of NITEMS items which are the indices + in the RITEM vector of the items that are selected in this state. + + The two types of actions are shifts/gotos (push the lookahead token + and read another/goto to the state designated by a nterm) and + reductions (combine the last n things on the stack via a rule, + replace them with the symbol that the rule derives, and leave the + lookahead token alone).

It + leads to a next-to-final state whose accessing_symbol is the + grammar's start symbol. The next-to-final state has one shift to + the final state, whose accessing_symbol is zero (end of input). + The final state has one shift, which goes to the termination state. + The reason for the extra state at the end is to placate the + parser's strategy of making all decisions one token ahead of its + actions. */ + +#ifndef STATE_H_ +# define STATE_H_ + +# include + +# include "gram.h" +# include "symtab.h" + + +/*-------------------. +| Numbering states. | +`-------------------*/ + +typedef int state_number; +# define STATE_NUMBER_MAXIMUM INT_MAX + +/* Be ready to map a state_number to an int. */ +static inline int +state_number_as_int (state_number s) +{ + return s; +} + + +typedef struct state state; + +/*--------------. +| Transitions. | +`--------------*/ + +typedef struct +{ + int num; + state *states[1]; +} transitions; + + +/* What is the symbol labelling the transition to + TRANSITIONS->states[Num]?
