Fix the calculation of the number of physical characters in the prompt + string when it contains multibyte characters. + +i. A non-zero value for the `rl_complete_suppress_append' variable now causes + no `/' to be appended to a directory name. + +j. Fixed forward-word and backward-word to work when words contained + multibyte characters. + +k. Fixed a bug in finding the delimiter of a `?' substring when performing + history expansion in a locale that supports multibyte characters. + +l. Fixed a memory leak caused by not freeing the timestamp in a history entry. + +m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting + of the `convert-meta' variable. + +n. Fixed saving and restoring primary prompt when prompting for incremental + and non-incremental searches; search prompts now display multibyte + characters correctly. + +o. Fixed a bug that caused keys originally bound to self-insert but shadowed + by a multi-character key sequence to not be inserted. + +p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't + dereferenced if NULL (matching the documentation). + +q. Extensive changes to readline to add enough state so that commands + requiring additional characters (searches, multi-key sequences, numeric + arguments, commands requiring an additional specifier character like + vi-mode change-char, etc.) work without synchronously waiting for + additional input. + +r. Lots of changes so readline builds and runs on MinGW. + +s. Readline no longer tries to modify the terminal settings when running in + callback mode. + +t. The Readline display code no longer sets the location of the last invisible + character in the prompt if the \[\] sequence is empty. + +u. The `change-case' command now correctly changes the case of multibyte + characters. + +v. Changes to the shared library construction scripts to deal with Windows + DLL naming conventions for Cygwin. + +w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed + SIGWINCH. + +x. Fixed the non-incremental search code in vi mode to dispose of any current + undo list when copying a line from the history into the current editing + buffer. + +y. Fixed a bug that caused reversing the incremental search direction to + not work correctly. + +z. Fixed the vi-mode `U' command to only undo up to the first time insert mode + was entered, as Posix specifies. + +aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong + place. + +bb. Fixed a redisplay bug caused by moving the cursor vertically to a line + with invisible characters in the prompt in a multibyte locale. + +cc.

The key sequence sent by the keypad `delete' key is now automatically + bound to delete-char. + +b. A negative argument to menu-complete now cycles backward through the + completion list. + +c. A new bindable readline variable: bind-tty-special-chars. If non-zero, + readline will bind the terminal special characters to their readline + equivalents when it's called (on by default). + +d. New bindable command: vi-rubout. Saves deleted text for possible + reinsertion, as with any vi-mode `text modification' command; `X' is bound + to this in vi command mode. + +e. If the rl_completion_query_items is set to a value < 0, readline never + asks the user whether or not to view the possible completions. + +f.

Changes to Readline + +a. Fixes to avoid core dumps because of null pointer references in the + multibyte character code. + +b. Fix to avoid infinite recursion caused by certain key combinations. + +c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly. + +d. Readline no longer tries to read ahead more than one line of input, even + when more is available. + +e. Fixed the code that adjusts the point to not mishandle null wide + characters. + +f. Fixed a bug in the history expansion `g' modifier that caused it to skip + every other match. + +g. Fixed a bug that caused the prompt to overwrite previous output when the + output doesn't contain a newline and the locale supports multibyte + characters. This same change fixes the problem of readline redisplay + slowing down dramatically as the line gets longer in multibyte locales. + +h. History traversal with arrow keys in vi insertion mode causes the cursor + to be placed at the end of the new line, like in emacs mode. + +i. The locale initialization code does a better job of using the right + precedence and defaulting when checking the appropriate environment + variables. + +j. Fixed the history word tokenizer to handle <( and >( better when used as + part of bash. + +k. The overwrite mode code received several bug fixes to improve undo. + +l. Many speedups to the multibyte character redisplay code. + +m. The callback character reading interface should not hang waiting to read + keyboard input. + +n. Fixed a bug with redoing vi-mode `s' command. + +o. The code that initializes the terminal tracks changes made to the terminal + special characters with stty(1) (or equivalent), so that these changes + are reflected in the readline bindings. New application-callable function + to make it work: rl_tty_unset_default_bindings(). + +p. Fixed a bug that could cause garbage to be inserted in the buffer when + changing character case in vi mode when using a multibyte locale. + +q. Fixed a bug in the redisplay code that caused problems on systems + supporting multibyte characters when moving between history lines when the + new line has more glyphs but fewer bytes. + +r. Undo and redo now work better after exiting vi insertion mode. + +s. Make sure system calls are restarted after a SIGWINCH is received using + SA_RESTART. + +t. Improvements to the code that displays possible completions when using + multibyte characters. + +u. Fixed a problem when parsing nested if statements in inputrc files. + +v. The completer now takes multibyte characters into account when looking for + quoted substrings on which to perform completion. + +w. The history search functions now perform better bounds checking on the + history list. + +x. Change to history expansion functions to treat `^' as equivalent to word + one, as the documention states. + +y. Some changes to the display code to improve display and redisplay of + multibyte characters. + +z. Changes to speed up the multibyte character redisplay code. + +aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the + last character of a word if invoked while point was on the word's + next-to-last character. + +bb. Fixed a bug that could cause incorrect filename quoting when + case-insensitive completion was enabled and the word being completed + contained backslashes quoting word break characters. + +cc. Fixed a bug in redisplay triggered when the prompt string contains + invisible characters. + +dd. Fixed some display (and other) bugs encountered in multibyte locales + when a non-ascii character was the last character on a line. + +ee. Fixed some display bugs caused by multibyte characters in prompt strings. + +ff. Fixed a problem with history expansion caused by non-whitespace characters + used as history word delimiters. + +gg. Fixed a problem that could cause readline to refer to freed memory when + moving between history lines while doing searches. + +hh. Improvements to the code that expands and displays prompt strings + containing multibyte characters. + +ii. Fixed a problem with vi-mode not correctly remembering the numeric argument + to the last `c'hange command for later use with `.'. + +jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work + incorrectly. + +kk. Fixed a problem in vi-mode that caused the last text modification command + to not be remembered across different command lines. + +ll. Fixed problems with changing characters and changing case at the end of + the line. + +mm. Fixed a problem with readline saving the contents of the current line + before beginning a non-interactive search. + +nn. Fixed a problem with EOF detection when using rl_event_hook. + +oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric + arguments. + +2. New Features in Readline + +a. History expansion has a new `a' modifier equivalent to the `g' modifier + for compatibility with the BSD csh. + +b. History expansion has a new `G' modifier equivalent to the BSD csh `g' + modifier, which performs a substitution once per word. + +c. All non-incremental search operations may now undo the operation of + replacing the current line with the history line. + +d. The text inserted by an `a' command in vi mode can be reinserted with + `.'. + +e. New bindable variable, `show-all-if-unmodified'. If set, the readline + completer will list possible completions immediately if there is more + than one completion and partial completion cannot be performed. + +f. There is a new application-callable `free_history_entry()' function. + +g. History list entries now contain timestamp information; the history file + functions know how to read and write timestamp information associated + with each entry. + +h. Four new key binding functions have been added: + + rl_bind_key_if_unbound() + rl_bind_key_if_unbound_in_map() + rl_bind_keyseq_if_unbound() + rl_bind_keyseq_if_unbound_in_map() + +i. New application variable, rl_completion_quote_character, set to any + quote character readline finds before it calls the application completion + function. + +j. New application variable, rl_completion_suppress_quote, settable by an + application completion function. If set to non-zero, readline does not + attempt to append a closing quote to a completed word. + +k. New application variable, rl_completion_found_quote, set to a non-zero + value if readline determines that the word to be completed is quoted. + Set before readline calls any application completion function. + +l. New function hook, rl_completion_word_break_hook, called when readline + needs to break a line into words when completion is attempted. Allows + the word break characters to vary based on position in the line. + +m. New bindable command: unix-filename-rubout. Does the same thing as + unix-word-rubout, but adds `/' to the set of word delimiters. + +n. When listing completions, directories have a `/' appended if the + `mark-directories' option has been enabled. + +------------------------------------------------------------------------------- This document details the changes between this version, readline-4.3, and the previous version, readline-4.2a. diff --git a/readline/INSTALL b/readline/INSTALL index adb27a9..1a73c77 100644 --- a/readline/INSTALL +++ b/readline/INSTALL @@ -1,7 +1,7 @@ Basic Installation ================== -These are installation instructions for Readline-4.3. +These are installation instructions for Readline-5.1.

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.

A.1 GNU Free Documentation License

+ +

+ + +

+ Version 1.2, November 2002 +
+

+ +
 
Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+

+ +

    +
  1. +PREAMBLE +

    + +The purpose of this License is to make a manual, textbook, or other +functional and useful document free in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +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. +

    + +

  2. +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. +

    + +

  3. +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. +

    + +

  4. +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. +

    + +

  5. +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: +

    + +

      +
    1. +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. +

      + +

    2. +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. +

      + +

    3. +State on the Title page the name of the publisher of the +Modified Version, as the publisher. +

      + +

    4. +Preserve all the copyright notices of the Document. +

      + +

    5. +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. +

      + +

    6. +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. +

      + +

    7. +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. +

      + +

    8. +Include an unaltered copy of this License. +

      + +

    9. +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. +

      + +

    10. +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. +

      + +

    11. +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. +

      + +

    12. +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. +

      + +

    13. +Delete any section Entitled "Endorsements". Such a section +may not be included in the Modified Version. +

      + +

    14. +Do not retitle any existing section to be Entitled "Endorsements" or +to conflict in title with any Invariant Section. +

      + +

    15. +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. +

    + +

  6. +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." +

    + +

  7. +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. +

    + +

  8. +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 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. +

    + +

  9. +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. +

    + +

  10. +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. +

    + +

  11. +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. +

A.1.1 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. +

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 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. + +A.1.1 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: history.info, Node: Concept Index, Next: Function and Variable Index, Prev: Copying This Manual, Up: Top -Concept Index -************* +Appendix B Concept Index +************************ +[index] * Menu: * anchored search: Searching the History List. -* event designators: Event Designators. -* history events: Event Designators. -* history expansion: History Interaction. + (line 10) +* event designators: Event Designators.

What is the GNU History library for? +* History Storage:: How information is stored. +* History Functions:: Functions that you can use. +* History Variables:: Variables that control behaviour. +* History Programming Example:: Example of using the GNU History Library. +@end menu + +@node Introduction to History +@section Introduction to History + +Many programs read input from the user a line at a time. The @sc{gnu} +History library is able to keep track of those lines, associate arbitrary +data with each line, and utilize information from previous lines in +composing new ones. + +The programmer using the History library has available functions +for remembering lines on a history list, associating arbitrary data +with a line, removing lines from the list, searching through the list +for a line containing an arbitrary text string, and referencing any line +in the list directly. In addition, a history @dfn{expansion} function +is available which provides for a consistent user interface across +different programs. + +The user using programs written with the History library has the +benefit of a consistent user interface with a set of well-known +commands for manipulating the text of previous lines and using that text +in new commands. The basic history manipulation commands are similar to +the history substitution provided by @code{csh}. + +If the programmer desires, he can use the Readline library, which +includes some history manipulation by default, and has the added +advantage of command line editing. + +Before declaring any functions using any functionality the History +library provides in other code, an application writer should include +the file @code{} in any file that uses the +History library's features. It supplies extern declarations for all +of the library's public functions and variables, and declares all of +the public data structures. + +@node History Storage +@section History Storage + +The history list is an array of history entries. A history entry is +declared as follows: + +@example +typedef void *histdata_t; + +typedef struct _hist_entry @{ + char *line; + char *timestamp; + histdata_t data; +@} HIST_ENTRY; +@end example + +The history list itself might therefore be declared as + +@example +HIST_ENTRY **the_history_list; +@end example + +The state of the History library is encapsulated into a single structure: + +@example +/* + * A structure used to pass around the current state of the history. + */ +typedef struct _hist_state @{ + HIST_ENTRY **entries; /* Pointer to the entries themselves. */ + int offset; /* The location pointer within this array. */ + int length; /* Number of elements within this array. */ + int size; /* Number of slots allocated to this array. */ + int flags; +@} HISTORY_STATE; +@end example + +If the flags member includes @code{HS_STIFLED}, the history has been +stifled. + +@node History Functions +@section History Functions + +This section describes the calling sequence for the various functions +exported by the @sc{gnu} History library. + +@menu +* Initializing History and State Management:: Functions to call when you + want to use history in a + program. +* History List Management:: Functions used to manage the list + of history entries. +* Information About the History List:: Functions returning information about + the history list. +* Moving Around the History List:: Functions used to change the position + in the history list. +* Searching the History List:: Functions to search the history list + for entries containing a string. +* Managing the History File:: Functions that read and write a file + containing the history list. +* History Expansion:: Functions to perform csh-like history + expansion. +@end menu + +@node Initializing History and State Management +@subsection Initializing History and State Management + +This section describes functions used to initialize and manage +the state of the History library when you want to use the history +functions in your program. + +@deftypefun void using_history (void) +Begin a session in which the history functions might be used.

After saving the history, the history file is truncated +to contain no more than @env{$HISTFILESIZE} +lines. If @env{HISTFILESIZE} is not set, no truncation is performed. + +If the @env{HISTTIMEFORMAT} is set, the time stamp information +associated with each history entry is written to the history file. + +The builtin command @code{fc} may be used to list or edit and re-execute +a portion of the history list. +The @code{history} builtin may be used to display or modify the history +list and manipulate the history file. +When using command-line editing, search commands +are available in each editing mode that provide access to the +history list (@pxref{Commands For History}). + +The shell allows control over which commands are saved on the history +list. The @env{HISTCONTROL} and @env{HISTIGNORE} +variables may be set to cause the shell to save only a subset of the +commands entered. +The @code{cmdhist} +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The @code{lithist} +shell option causes the shell to save the command with embedded newlines +instead of semicolons. +The @code{shopt} builtin is used to set these options. +@xref{Bash Builtins}, for a description of @code{shopt}. + +@node Bash History Builtins +@section Bash History Builtins +@cindex history builtins + +Bash provides two builtin commands which manipulate the +history list and history file. + +@table @code + +@item fc +@btindex fc +@example +@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]} +@code{fc -s [@var{pat}=@var{rep}] [@var{command}]} +@end example + +Fix Command. In the first form, a range of commands from @var{first} to +@var{last} is selected from the history list. Both @var{first} and +@var{last} may be specified as a string (to locate the most recent +command beginning with that string) or as a number (an index into the +history list, where a negative number is used as an offset from the +current command number). If @var{last} is not specified it is set to +@var{first}. If @var{first} is not specified it is set to the previous +command for editing and @minus{}16 for listing. If the @option{-l} flag is +given, the commands are listed on standard output. The @option{-n} flag +suppresses the command numbers when listing. The @option{-r} flag +reverses the order of the listing. Otherwise, the editor given by +@var{ename} is invoked on a file containing those commands. If +@var{ename} is not given, the value of the following variable expansion +is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}. This says to use the +value of the @env{FCEDIT} variable if set, or the value of the +@env{EDITOR} variable if that is set, or @code{vi} if neither is set. +When editing is complete, the edited commands are echoed and executed. + +In the second form, @var{command} is re-executed after each instance +of @var{pat} in the selected command is replaced by @var{rep}. + +A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so +that typing @samp{r cc} runs the last command beginning with @code{cc} +and typing @samp{r} re-executes the last command (@pxref{Aliases}). + +@item history +@btindex history +@example +history [@var{n}] +history -c +history -d @var{offset} +history [-anrw] [@var{filename}] +history -ps @var{arg} +@end example + +With no options, display the history list with line numbers. +Lines prefixed with a @samp{*} have been modified. +An argument of @var{n} lists only the last @var{n} lines. +If the shell variable @env{HISTTIMEFORMAT} is set and not null, +it is used as a format string for @var{strftime} to display +the time stamp associated with each displayed history entry. +No intervening blank is printed between the formatted time stamp +and the history line. + +Options, if supplied, have the following meanings: + +@table @code +@item -c +Clear the history list.

This section +describes the syntax used to manipulate the history information. + +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. + +History expansion takes place in two parts. The first is to determine +which line from the history list should be used during substitution. +The second is to select portions of that line for inclusion into the +current one. The line selected from the history is called the +@dfn{event}, and the portions of that line that are acted upon are +called @dfn{words}. Various @dfn{modifiers} are available to manipulate +the selected words. The line is broken into words in the same fashion +that Bash does, so that several words +surrounded by quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is @samp{!} by default. +@ifset BashFeatures +Only @samp{\} and @samp{'} may be used to escape the history expansion +character. +@end ifset + +@ifset BashFeatures +Several shell options settable with the @code{shopt} +builtin (@pxref{Bash Builtins}) may be used to tailor +the behavior of history expansion. If the +@code{histverify} shell option is enabled, and Readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the Readline +editing buffer for further modification. +If Readline is being used, and the @code{histreedit} +shell option is enabled, a failed history expansion will be +reloaded into the Readline editing buffer for correction. +The @option{-p} option to the @code{history} builtin command +may be used to see what a history expansion will do before using it. +The @option{-s} option to the @code{history} builtin may be used to +add commands to the end of the history list without actually executing +them, so that they are available for subsequent recall. +This is most useful in conjunction with Readline. + +The shell allows control of the various characters used by the +history expansion mechanism with the @code{histchars} variable. +@end ifset + +@menu +* Event Designators:: How to specify which history line to use. +* Word Designators:: Specifying which words are of interest. +* Modifiers:: Modifying the results of substitution. +@end menu + +@node Event Designators +@subsection Event Designators +@cindex event designators + +An event designator is a reference to a command line entry in the +history list. +@cindex history events + +@table @asis + +@item @code{!} +@ifset BashFeatures +Start a history substitution, except when followed by a space, tab, +the end of the line, @samp{=} or @samp{(} (when the +@code{extglob} shell option is enabled using the @code{shopt} builtin). +@end ifset +@ifclear BashFeatures +Start a history substitution, except when followed by a space, tab, +the end of the line, or @samp{=}. +@end ifclear + +@item @code{!@var{n}} +Refer to command line @var{n}. + +@item @code{!-@var{n}} +Refer to the command @var{n} lines back. + +@item @code{!!} +Refer to the previous command.

    + +The purpose of this License is to make a manual, textbook, or other +functional and useful document free in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +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. +

    + +

  2. +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. +

    + +

  3. +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. +

    + +

  4. +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. +

    + +

  5. +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: +

    + +

      +
    1. +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. +

      + +

    2. +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. +

      + +

    3. +State on the Title page the name of the publisher of the +Modified Version, as the publisher. +

      + +

    4. +Preserve all the copyright notices of the Document. +

      + +

    5. +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. +

      + +

    6. +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. +

      + +

    7. +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. +

      + +

    8. +Include an unaltered copy of this License. +

      + +

    9. +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. +

      + +

    10. +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. +

      + +

    11. +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. +

      + +

    12. +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. +

      + +

    13. +Delete any section Entitled "Endorsements". Such a section +may not be included in the Modified Version. +

      + +

    14. +Do not retitle any existing section to be Entitled "Endorsements" or +to conflict in title with any Invariant Section. +

      + +

    15. +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. +

    + +

  6. +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." +

    + +

  7. +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. +

    + +

  8. +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 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. +

    + +

  9. +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. +

    + +

  10. +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. +

    + +

  11. +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. +

A.1.1 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. +

PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document "free" in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. 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 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.

For such programs, the default behaviour of +Readline is sufficient. This section describes how to use Readline in +the simplest way possible, perhaps to replace calls in your code to +@code{gets()} or @code{fgets()}. + +@findex readline +@cindex readline, function + +The function @code{readline()} prints a prompt @var{prompt} +and then reads and returns a single line of text from the user. +If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed. +The line @code{readline} returns is allocated with @code{malloc()}; +the caller should @code{free()} the line when it has finished with it. +The declaration for @code{readline} in ANSI C is + +@example +@code{char *readline (const char *@var{prompt});} +@end example + +@noindent +So, one might say +@example +@code{char *line = readline ("Enter a line: ");} +@end example +@noindent +in order to read a line of text from the user. +The line returned has the final newline removed, so only the +text remains. + +If @code{readline} encounters an @code{EOF} while reading the line, and the +line is empty at that point, then @code{(char *)NULL} is returned. +Otherwise, the line is ended just as if a newline had been typed. + +If you want the user to be able to get at the line later, (with +@key{C-p} for example), you must call @code{add_history()} to save the +line away in a @dfn{history} list of such lines. + +@example +@code{add_history (line)}; +@end example + +@noindent +For full details on the GNU History Library, see the associated manual. + +It is preferable to avoid saving empty lines on the history list, since +users rarely have a burning need to reuse a blank line. Here is +a function which usefully replaces the standard @code{gets()} library +function, and has the advantage of no static buffer to overflow: + +@example +/* A static variable for holding the line. */ +static char *line_read = (char *)NULL; + +/* Read a string, and return a pointer to it. + Returns NULL on EOF. */ +char * +rl_gets () +@{ + /* If the buffer has already been allocated, + return the memory to the free pool. */ + if (line_read) + @{ + free (line_read); + line_read = (char *)NULL; + @} + + /* Get a line from the user. */ + line_read = readline (""); + + /* If the line has any text in it, + save it on the history. */ + if (line_read && *line_read) + add_history (line_read); + + return (line_read); +@} +@end example + +This function gives the user the default behaviour of @key{TAB} +completion: completion on file names. If you do not want Readline to +complete on filenames, you can change the binding of the @key{TAB} key +with @code{rl_bind_key()}. + +@example +@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});} +@end example + +@code{rl_bind_key()} takes two arguments: @var{key} is the character that +you want to bind, and @var{function} is the address of the function to +call when @var{key} is pressed. Binding @key{TAB} to @code{rl_insert()} +makes @key{TAB} insert itself. +@code{rl_bind_key()} returns non-zero if @var{key} is not a valid +ASCII character code (between 0 and 255). + +Thus, to disable the default @key{TAB} behavior, the following suffices: +@example +@code{rl_bind_key ('\t', rl_insert);} +@end example + +This code should be executed once at the start of your program; you +might write a function called @code{initialize_readline()} which +performs this and other desired initializations, such as installing +custom completers (@pxref{Custom Completers}). + +@node Custom Functions +@section Custom Functions + +Readline provides many functions for manipulating the text of +the line, but it isn't possible to anticipate the needs of all +programs. This section describes the various functions and variables +defined within the Readline library which allow a user program to add +customized functionality to Readline. + +Before declaring any functions that customize Readline's behavior, or +using any functionality Readline provides in other code, an +application writer should include the file @code{} +in any file that uses Readline's features. Since some of the definitions +in @code{readline.h} use the @code{stdio} library, the file +@code{} should be included before @code{readline.h}. + +@code{readline.h} defines a C preprocessor variable that should +be treated as an integer, @code{RL_READLINE_VERSION}, which may +be used to conditionally compile application code depending on +the installed Readline version. The value is a hexadecimal +encoding of the major and minor version numbers of the library, +of the form 0x@var{MMmm}. @var{MM} is the two-digit major +version number; @var{mm} is the two-digit minor version number. +For Readline 4.2, for example, the value of +@code{RL_READLINE_VERSION} would be @code{0x0402}. + +@menu +* Readline Typedefs:: C declarations to make code readable. +* Function Writing:: Variables and calling conventions. +@end menu + +@node Readline Typedefs +@subsection Readline Typedefs + +For readabilty, we declare a number of new object types, all pointers +to functions. + +The reason for declaring these new types is to make it easier to write +code describing pointers to C functions with appropriately prototyped +arguments and return values. + +For instance, say we want to declare a variable @var{func} as a pointer +to a function which takes two @code{int} arguments and returns an +@code{int} (this is the type of all of the Readline bindable functions). +Instead of the classic C declaration + +@code{int (*func)();} + +@noindent +or the ANSI-C style declaration + +@code{int (*func)(int, int);} + +@noindent +we may write + +@code{rl_command_func_t *func;} + +The full list of function pointer types available is + +@table @code +@item typedef int rl_command_func_t (int, int); + +@item typedef char *rl_compentry_func_t (const char *, int); + +@item typedef char **rl_completion_func_t (const char *, int, int); + +@item typedef char *rl_quote_func_t (char *, int, char *); + +@item typedef char *rl_dequote_func_t (char *, int); + +@item typedef int rl_compignore_func_t (char **); + +@item typedef void rl_compdisp_func_t (char **, int, int); + +@item typedef int rl_hook_func_t (void); + +@item typedef int rl_getc_func_t (FILE *); + +@item typedef int rl_linebuf_func_t (char *, int); + +@item typedef int rl_intfunc_t (int); +@item #define rl_ivoidfunc_t rl_hook_func_t +@item typedef int rl_icpfunc_t (char *); +@item typedef int rl_icppfunc_t (char **); + +@item typedef void rl_voidfunc_t (void); +@item typedef void rl_vintfunc_t (int); +@item typedef void rl_vcpfunc_t (char *); +@item typedef void rl_vcppfunc_t (char **); + +@end table + +@node Function Writing +@subsection Writing a New Function + +In order to write new functions for Readline, you need to know the +calling conventions for keyboard-invoked functions, and the names of the +variables that describe the current state of the line read so far. + +The calling sequence for a command @code{foo} looks like + +@example +@code{int foo (int count, int key)} +@end example + +@noindent +where @var{count} is the numeric argument (or 1 if defaulted) and +@var{key} is the key that invoked this function. + +It is completely up to the function as to what should be done with the +numeric argument. Some functions use it as a repeat count, some +as a flag, and others to choose alternate behavior (refreshing the current +line as opposed to refreshing the screen, for example). Some choose to +ignore it. In general, if a +function uses the numeric argument as a repeat count, it should be able +to do something useful with both negative and positive arguments. +At the very least, it should be aware that it can be passed a +negative argument. + +A command function should return 0 if its action completes successfully, +and a non-zero value if some error occurs. +This is the convention obeyed by all of the builtin Readline bindable +command functions. + +@node Readline Variables +@section Readline Variables + +These variables are available to function writers. + +@deftypevar {char *} rl_line_buffer +This is the line gathered so far.

This is a +way to stuff a single character into the input stream. +@end deftypevar + +@deftypevar int rl_dispatching +Set to a non-zero value if a function is being called from a key binding; +zero otherwise. Application functions can test this to discover whether +they were called directly or by Readline's dispatching mechanism. +@end deftypevar + +@deftypevar int rl_erase_empty_line +Setting this to a non-zero value causes Readline to completely erase +the current line, including any prompt, any time a newline is typed as +the only character on an otherwise-empty line.

They are intended to indicate +exceptional events, like a user pressing the interrupt key on his terminal, +or a network connection being broken. There is a class of signals that can +be sent to the process currently reading input from the keyboard. Since +Readline changes the terminal attributes when it is called, it needs to +perform special processing when such a signal is received in order to +restore the terminal to a sane state, or provide application writers with +functions to do so manually. + +Readline contains an internal signal handler that is installed for a +number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, +@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}). +When one of these signals is received, the signal handler +will reset the terminal attributes to those that were in effect before +@code{readline()} was called, reset the signal handling to what it was +before @code{readline()} was called, and resend the signal to the calling +application. +If and when the calling application's signal handler returns, Readline +will reinitialize the terminal and continue to accept input. +When a @code{SIGINT} is received, the Readline signal handler performs +some additional work, which will cause any partially-entered line to be +aborted (see the description of @code{rl_free_line_state()} below). + +There is an additional Readline signal handler, for @code{SIGWINCH}, which +the kernel sends to a process whenever the terminal's size changes (for +example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH} +handler updates Readline's internal screen size information, and then calls +any @code{SIGWINCH} signal handler the calling application has installed. +Readline calls the application's @code{SIGWINCH} signal handler without +resetting the terminal to its original state. If the application's signal +handler does more than update its idea of the terminal size and return (for +example, a @code{longjmp} back to a main processing loop), it @emph{must} +call @code{rl_cleanup_after_signal()} (described below), to restore the +terminal state. + +Readline provides two variables that allow application writers to +control whether or not it will catch certain signals and act on them +when they are received. It is important that applications change the +values of these variables only when calling @code{readline()}, not in +a signal handler, so Readline's internal signal state is not corrupted. + +@deftypevar int rl_catch_signals +If this variable is non-zero, Readline will install signal handlers for +@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM}, +@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}. + +The default value of @code{rl_catch_signals} is 1. +@end deftypevar + +@deftypevar int rl_catch_sigwinch +If this variable is non-zero, Readline will install a signal handler for +@code{SIGWINCH}. + +The default value of @code{rl_catch_sigwinch} is 1. +@end deftypevar + +If an application does not wish to have Readline catch any signals, or +to handle signals other than those Readline catches (@code{SIGHUP}, +for example), +Readline provides convenience functions to do the necessary terminal +and internal state cleanup upon receipt of a signal. + +@deftypefun void rl_cleanup_after_signal (void) +This function will reset the state of the terminal to what it was before +@code{readline()} was called, and remove the Readline signal handlers for +all signals, depending on the values of @code{rl_catch_signals} and +@code{rl_catch_sigwinch}. +@end deftypefun + +@deftypefun void rl_free_line_state (void) +This will free any partial state associated with the current input line +(undo information, any partial history entry, any partially-entered +keyboard macro, and any partially-entered numeric argument).

That is, it is not possible to accurately +expand a partial word without knowing all of the possible words +which make sense in that context. The Readline library provides +the user interface to completion, and two of the most common +completion functions: filename and username. For completing other types +of text, you must write your own completion function. This section +describes exactly what such functions must do, and provides an example. + +There are three major functions used to perform completion: + +@enumerate +@item +The user-interface function @code{rl_complete()}. This function is +called with the same arguments as other bindable Readline functions: +@var{count} and @var{invoking_key}. +It isolates the word to be completed and calls +@code{rl_completion_matches()} to generate a list of possible completions. +It then either lists the possible completions, inserts the possible +completions, or actually performs the +completion, depending on which behavior is desired. + +@item +The internal function @code{rl_completion_matches()} uses an +application-supplied @dfn{generator} function to generate the list of +possible matches, and then returns the array of these matches. +The caller should place the address of its generator function in +@code{rl_completion_entry_function}. + +@item +The generator function is called repeatedly from +@code{rl_completion_matches()}, returning a string each time. The +arguments to the generator function are @var{text} and @var{state}. +@var{text} is the partial word to be completed. @var{state} is zero the +first time the function is called, allowing the generator to perform +any necessary initialization, and a positive non-zero integer for +each subsequent call. The generator function returns +@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are +no more possibilities left. Usually the generator function computes the +list of possible completions when @var{state} is zero, and returns them +one at a time on subsequent calls. Each string the generator function +returns as a match must be allocated with @code{malloc()}; Readline +frees the strings when it has finished with them. +Such a generator function is referred to as an +@dfn{application-specific completion function}. + +@end enumerate + +@deftypefun int rl_complete (int ignore, int invoking_key) +Complete the word at or before point.

Specifically, +@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all +stand for themselves when seen in this text, or in an init file +(@pxref{Readline Init File}). +If your keyboard lacks a @key{LFD} key, typing @key{C-j} will +produce the desired character. +The @key{RET} key may be labeled @key{Return} or @key{Enter} on +some keyboards. + +@node Readline Interaction +@section Readline Interaction +@cindex interaction, readline + +Often during an interactive session you type in a long line of text, +only to notice that the first word on the line is misspelled. The +Readline library gives you a set of commands for manipulating the text +as you type it in, allowing you to just fix your typo, and not forcing +you to retype the majority of the line. Using these editing commands, +you move the cursor to the place that needs correction, and delete or +insert the text of the corrections. Then, when you are satisfied with +the line, you simply press @key{RET}. You do not have to be at the +end of the line to press @key{RET}; the entire line is accepted +regardless of the location of the cursor within the line. + +@menu +* Readline Bare Essentials:: The least you need to know about Readline. +* Readline Movement Commands:: Moving about the input line. +* Readline Killing Commands:: How to delete text, and how to get it back! +* Readline Arguments:: Giving numeric arguments to commands. +* Searching:: Searching through previous lines. +@end menu + +@node Readline Bare Essentials +@subsection Readline Bare Essentials +@cindex notation, readline +@cindex command editing +@cindex editing command lines + +In order to enter characters into the line, simply type them. The typed +character appears where the cursor was, and then the cursor moves one +space to the right. If you mistype a character, you can use your +erase character to back up and delete the mistyped character. + +Sometimes you may mistype a character, and +not notice the error until you have typed several other characters. In +that case, you can type @kbd{C-b} to move the cursor to the left, and then +correct your mistake. Afterwards, you can move the cursor to the right +with @kbd{C-f}. + +When you add text in the middle of a line, you will notice that characters +to the right of the cursor are `pushed over' to make room for the text +that you have inserted. Likewise, when you delete text behind the cursor, +characters to the right of the cursor are `pulled back' to fill in the +blank space created by the removal of the text. A list of the bare +essentials for editing the text of an input line follows. + +@table @asis +@item @kbd{C-b} +Move back one character. +@item @kbd{C-f} +Move forward one character. +@item @key{DEL} or @key{Backspace} +Delete the character to the left of the cursor. +@item @kbd{C-d} +Delete the character underneath the cursor. +@item @w{Printing characters} +Insert the character into the line at the cursor. +@item @kbd{C-_} or @kbd{C-x C-u} +Undo the last editing command. You can undo all the way back to an +empty line. +@end table + +@noindent +(Depending on your configuration, the @key{Backspace} key be set to +delete the character to the left of the cursor and the @key{DEL} key set +to delete the character underneath the cursor, like @kbd{C-d}, rather +than the character to the left of the cursor.) + +@node Readline Movement Commands +@subsection Readline Movement Commands + + +The above table describes the most basic keystrokes that you need +in order to do editing of the input line. For your convenience, many +other commands have been added in addition to @kbd{C-b}, @kbd{C-f}, +@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly +about the line. + +@table @kbd +@item C-a +Move to the start of the line. +@item C-e +Move to the end of the line. +@item M-f +Move forward a word, where a word is composed of letters and digits. +@item M-b +Move backward a word. +@item C-l +Clear the screen, reprinting the current line at the top. +@end table + +Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves +forward a word. It is a loose convention that control keystrokes +operate on characters while meta keystrokes operate on words. + +@node Readline Killing Commands +@subsection Readline Killing Commands + +@cindex killing text +@cindex yanking text + +@dfn{Killing} text means to delete the text from the line, but to save +it away for later use, usually by @dfn{yanking} (re-inserting) +it back into the line. +(`Cut' and `paste' are more recent jargon for `kill' and `yank'.) + +If the description for a command says that it `kills' text, then you can +be sure that you can get the text back in a different (or the same) +place later. + +When you use a kill command, the text is saved in a @dfn{kill-ring}. +Any number of consecutive kills save all of the killed text together, so +that when you yank it back, you get it all. The kill +ring is not line specific; the text that you killed on a previously +typed line is available to be yanked back later, when you are typing +another line. +@cindex kill ring + +Here is the list of commands for killing text. + +@table @kbd +@item C-k +Kill the text from the current cursor position to the end of the line. + +@item M-d +Kill from the cursor to the end of the current word, or, if between +words, to the end of the next word. +Word boundaries are the same as those used by @kbd{M-f}. + +@item M-@key{DEL} +Kill from the cursor the start of the current word, or, if between +words, to the start of the previous word. +Word boundaries are the same as those used by @kbd{M-b}. + +@item C-w +Kill from the cursor to the previous whitespace. This is different than +@kbd{M-@key{DEL}} because the word boundaries differ. + +@end table + +Here is how to @dfn{yank} the text back into the line. Yanking +means to copy the most-recently-killed text from the kill buffer. + +@table @kbd +@item C-y +Yank the most recently killed text back into the buffer at the cursor. + +@item M-y +Rotate the kill-ring, and yank the new top. You can only do this if +the prior command is @kbd{C-y} or @kbd{M-y}. +@end table + +@node Readline Arguments +@subsection Readline Arguments + +You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the @i{sign} of the +argument that is significant. If you pass a negative argument to a +command which normally acts in a forward direction, that command will +act in a backward direction. For example, to kill text back to the +start of the line, you might type @samp{M-- C-k}. + +The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first `digit' typed is a minus +sign (@samp{-}), then the sign of the argument will be negative. Once +you have typed one meta digit to get the argument started, you can type +the remainder of the digits, and then the command. For example, to give +the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}, +which will delete the next ten characters on the input line. + +@node Searching +@subsection Searching for Commands in the History + +Readline provides commands for searching through the command history +@ifset BashFeatures +(@pxref{Bash History Facilities}) +@end ifset +for lines containing a specified string. +There are two search modes: @dfn{incremental} and @dfn{non-incremental}. + +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, Readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +To search backward in the history for a particular string, type +@kbd{C-r}. Typing @kbd{C-s} searches forward through the history. +The characters present in the value of the @code{isearch-terminators} variable +are used to terminate an incremental search. +If that variable has not been assigned a value, the @key{ESC} and +@kbd{C-J} characters will terminate an incremental search. +@kbd{C-g} will abort an incremental search and restore the original line. +When the search is terminated, the history entry containing the +search string becomes the current line. + +To find other matching entries in the history list, type @kbd{C-r} or +@kbd{C-s} as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a Readline command will terminate +the search and execute that command. +For instance, a @key{RET} will terminate the search and accept +the line, thereby executing the command from the history list. +A movement command will terminate the search, make the last line found +the current line, and begin editing. + +Readline remembers the last incremental search string. If two +@kbd{C-r}s are typed without any intervening characters defining a new +search string, any remembered search string is used. + +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. + +@node Readline Init File +@section Readline Init File +@cindex initialization file, readline + +Although the Readline library comes with a set of Emacs-like +keybindings installed by default, it is possible to use a different set +of keybindings. +Any user can customize programs that use Readline by putting +commands in an @dfn{inputrc} file, conventionally in his home directory. +The name of this +@ifset BashFeatures +file is taken from the value of the shell variable @env{INPUTRC}. If +@end ifset +@ifclear BashFeatures +file is taken from the value of the environment variable @env{INPUTRC}. If +@end ifclear +that variable is unset, the default is @file{~/.inputrc}. + +When a program which uses the Readline library starts up, the +init file is read, and the key bindings are set. + +In addition, the @code{C-x C-r} command re-reads this init file, thus +incorporating any changes that you might have made to it. + +@menu +* Readline Init File Syntax:: Syntax for the commands in the inputrc file. + +* Conditional Init Constructs:: Conditional key bindings in the inputrc file. + +* Sample Init File:: An example inputrc file. +@end menu + +@node Readline Init File Syntax +@subsection Readline Init File Syntax + +There are only a few basic constructs allowed in the +Readline init file. Blank lines are ignored. +Lines beginning with a @samp{#} are comments. +Lines beginning with a @samp{$} indicate conditional +constructs (@pxref{Conditional Init Constructs}). Other lines +denote variable settings and key bindings. + +@table @asis +@item Variable Settings +You can modify the run-time behavior of Readline by +altering the values of variables in Readline +using the @code{set} command within the init file. +The syntax is simple: + +@example +set @var{variable} @var{value} +@end example + +@noindent +Here, for example, is how to +change from the default Emacs-like key binding to use +@code{vi} line editing commands: + +@example +set editing-mode vi +@end example + +Variable names and values, where appropriate, are recognized without regard +to case. Unrecognized variable names are ignored. + +Boolean variables (those that can be set to on or off) are set to on if +the value is null or empty, @var{on} (case-insensitive), or 1. Any other +value results in the variable being set to off. + +@ifset BashFeatures +The @w{@code{bind -V}} command lists the current Readline variable names +and values. @xref{Bash Builtins}. +@end ifset + +A great deal of run-time behavior is changeable with the following +variables. + +@cindex variables, readline +@table @code + +@item bell-style +@vindex bell-style +Controls what happens when Readline wants to ring the terminal bell. +If set to @samp{none}, Readline never rings the bell. If set to +@samp{visible}, Readline uses a visible bell if one is available. +If set to @samp{audible} (the default), Readline attempts to ring +the terminal's bell. + +@item bind-tty-special-chars +@vindex bind-tty-special-chars +If set to @samp{on}, Readline attempts to bind the control characters +treated specially by the kernel's terminal driver to their Readline +equivalents. + +@item comment-begin +@vindex comment-begin +The string to insert at the beginning of the line when the +@code{insert-comment} command is executed. The default value +is @code{"#"}. + +@item completion-ignore-case +If set to @samp{on}, Readline performs filename matching and completion +in a case-insensitive fashion. +The default value is @samp{off}. + +@item completion-query-items +@vindex completion-query-items +The number of possible completions that determines when the user is +asked whether the list of possibilities should be displayed. +If the number of possible completions is greater than this value, +Readline will ask the user whether or not he wishes to view +them; otherwise, they are simply listed. +This variable must be set to an integer value greater than or equal to 0. +A negative value means Readline should never ask. +The default limit is @code{100}. + +@item convert-meta +@vindex convert-meta +If set to @samp{on}, Readline will convert characters with the +eighth bit set to an @sc{ascii} key sequence by stripping the eighth +bit and prefixing an @key{ESC} character, converting them to a +meta-prefixed key sequence. The default value is @samp{on}. + +@item disable-completion +@vindex disable-completion +If set to @samp{On}, Readline will inhibit word completion. +Completion characters will be inserted into the line as if they had +been mapped to @code{self-insert}. The default is @samp{off}. + +@item editing-mode +@vindex editing-mode +The @code{editing-mode} variable controls which default set of +key bindings is used. By default, Readline starts up in Emacs editing +mode, where the keystrokes are most similar to Emacs. This variable can be +set to either @samp{emacs} or @samp{vi}. + +@item enable-keypad +@vindex enable-keypad +When set to @samp{on}, Readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. The default is @samp{off}. + +@item expand-tilde +@vindex expand-tilde +If set to @samp{on}, tilde expansion is performed when Readline +attempts word completion. The default is @samp{off}. + +@item history-preserve-point +@vindex history-preserve-point +If set to @samp{on}, the history code attempts to place point at the +same location on each history line retrieved with @code{previous-history} +or @code{next-history}. The default is @samp{off}. + +@item horizontal-scroll-mode +@vindex horizontal-scroll-mode +This variable can be set to either @samp{on} or @samp{off}. Setting it +to @samp{on} means that the text of the lines being edited will scroll +horizontally on a single screen line when they are longer than the width +of the screen, instead of wrapping onto a new screen line.

First you need to find the name of the command that you +want to change. The following sections contain tables of the command +name, the default keybinding, if any, and a short description of what +the command does. + +Once you know the name of the command, simply place on a line +in the init file the name of the key +you wish to bind the command to, a colon, and then the name of the +command. The name of the key +can be expressed in different ways, depending on what you find most +comfortable. + +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a @var{macro}). + +@ifset BashFeatures +The @w{@code{bind -p}} command displays Readline function names and +bindings in a format that can put directly into an initialization file. +@xref{Bash Builtins}. +@end ifset + +@table @asis +@item @w{@var{keyname}: @var{function-name} or @var{macro}} +@var{keyname} is the name of a key spelled out in English.

There are four parser directives used. + +@table @code +@item $if +The @code{$if} construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +Readline. The text of the test extends to the end of the line; +no characters are required to isolate it. + +@table @code +@item mode +The @code{mode=} form of the @code{$if} directive is used to test +whether Readline is in @code{emacs} or @code{vi} mode. +This may be used in conjunction +with the @samp{set keymap} command, for instance, to set bindings in +the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if +Readline is starting out in @code{emacs} mode. + +@item term +The @code{term=} form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +@samp{=} is tested against both the full name of the terminal and +the portion of the terminal name before the first @samp{-}. This +allows @code{sun} to match both @code{sun} and @code{sun-cmd}, +for instance. + +@item application +The @var{application} construct is used to include +application-specific settings. Each program using the Readline +library sets the @var{application name}, and you can test for +a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +@example +$if Bash +# Quote the current or previous word +"\C-xq": "\eb\"\ef\"" +$endif +@end example +@end table + +@item $endif +This command, as seen in the previous example, terminates an +@code{$if} command. + +@item $else +Commands in this branch of the @code{$if} directive are executed if +the test fails. + +@item $include +This directive takes a single filename as an argument and reads commands +and bindings from that file. +For example, the following directive reads from @file{/etc/inputrc}: +@example +$include /etc/inputrc +@end example +@end table + +@node Sample Init File +@subsection Sample Init File + +Here is an example of an @var{inputrc} file.

+ Version 1.2, November 2002 +
+

Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+

+ +

    +
  1. +PREAMBLE +

    + +The purpose of this License is to make a manual, textbook, or other +functional and useful document free in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +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. +

    + +

  2. +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. +

    + +

  3. +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. +

    + +

  4. +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. +

    + +

  5. +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: +

    + +

      +
    1. +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. +

      + +

    2. +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. +

      + +

    3. +State on the Title page the name of the publisher of the +Modified Version, as the publisher. +

      + +

    4. +Preserve all the copyright notices of the Document. +

      + +

    5. +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. +

      + +

    6. +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. +

      + +

    7. +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. +

      + +

    8. +Include an unaltered copy of this License. +

      + +

    9. +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. +

      + +

    10. +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. +

      + +

    11. +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. +

      + +

    12. +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. +

      + +

    13. +Delete any section Entitled "Endorsements". Such a section +may not be included in the Modified Version. +

      + +

    14. +Do not retitle any existing section to be Entitled "Endorsements" or +to conflict in title with any Invariant Section. +

      + +

    15. +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. +

    + +

  6. +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." +

    + +

  7. +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. +

    + +

  8. +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 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. +

    + +

  9. +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. +

    + +

  10. +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. +

    + +

  11. +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. +

A.1.1 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. +

PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document "free" in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. 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 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. + +A.1.1 ADDENDUM: How to use this

It is a shared library that redirects calls to fgets(stdin) +to readline() via LD_PRELOAD, and it supports a custom prompt and list of +command names. Many people have asked me for this file, so I thought I'd +pass it your way in hope of just including it with readline to begin with. + +Best Regards, + +-Harold +*/ + +/****************************************************************************** +******************************************************************************* + + FILE NAME: fgets.c TARGET: libfgets.so + AUTHOR: Harold Levy VERSION: 1.0 + hlevy@synopsys.com + + ABSTRACT: Customize fgets() behavior via LD_PRELOAD in the following ways: + + -- If fgets(stdin) is called, redirect to GNU readline() to obtain + command-line editing, file-name completion, history, etc. + + -- A list of commands for command-name completion can be configured by + setting the environment-variable FGETS_COMMAND_FILE to a file containing + the list of commands to be used. + + -- Command-line editing with readline() works best when the prompt string + is known; you can set this with the FGETS_PROMPT environment variable. + + -- There special strings that libfgets will interpret as internal commands: + + _fgets_reset_ reset the command list + + _fgets_dump_ dump status + + _fgets_debug_ toggle debug messages + + HOW TO BUILD: Here are examples of how to build libfgets.so on various + platforms; you will have to add -I and -L flags to configure access to + the readline header and library files. + + (32-bit builds with gcc) + AIX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap + HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline + Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline + SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline + + (64-bit builds without gcc) + SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \ + -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline + + HOW TO USE: Different operating systems have different levels of support + for the LD_PRELOAD concept. The generic method for 32-bit platforms is to + put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths) + in the LD_PRELOAD environment variable, and to put their parent directories + in the LD_LIBRARY_PATH environment variable. Unfortunately there is no + generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have + to build both 32-bit and 64-bit libfgets and libreadline libraries, and + use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and + library_path configurations (a mix of 32-bit and 64-bit calls are made under + 64-bit SunOS). + + EXAMPLE WRAPPER: Here is an example shell script wrapper around the + program "foo" that uses fgets() for command-line input: + + #!/bin/csh + #### replace this with the libtermcap.so directory: + set dir1 = "/usr/lib" + #### replace this with the libfgets.so directory: + set dir2 = "/usr/fgets" + #### replace this with the libreadline.so directory: + set dir3 = "/usr/local/lib" + set lib1 = "${dir1}/libtermcap.so" + set lib2 = "${dir2}/libfgets.so" + set lib3 = "${dir3}/libreadline.so" + if ( "${?LD_PRELOAD}" ) then + setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}" + else + setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}" + endif + if ( "${?LD_LIBRARY_PATH}" ) then + setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}" + else + setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}" + endif + setenv FGETS_COMMAND_FILE "${dir2}/foo.commands" + setenv FGETS_PROMPT "foo> " + exec "foo" $* + + Copyright (C)©2003-2004 Harold Levy. + + This code links to the GNU readline library, and as such is bound by the + terms of the GNU General Public License as published by the Free Software + Foundation, either version 2 or (at your option) any later version. + + The GNU General Public License is often shipped with GNU software, and is + generally kept in a file called COPYING or LICENSE.

This basically means you can run your entire +session (including bash and terminal-mode emacs) under rlfe. + +FEATURES + +* Can use all readline commands (and history) in commands that +read input lines in "canonical mode" - even 'cat'! + +* Automatically switches between "readline-editing mode" and "raw mode" +depending on the terminal mode. If the inferior program invokes +readline itself, it will do its own line editing. (The inferior +readline will not know about rlfe, and it will have its own history.) +You can even run programs like 'emavs -nw' and 'vi' under rlfe. +The goal is you could leave rlfe always on without even knowing +about it.

To link with libreadline.a and libhistory.a +you can copy or link them, or add LDFLAGS='-/path/to/readline' to +the make command-line. + +USAGE + +Just run it. That by default runs bash. You can run some other +command by giving it as command-line arguments. + +There are a few tweaks: -h allows you to name the history file, +and -s allows you to specify its size. It default to "emacs" mode, +but if the the environment variable EDITOR is set to "vi" that +mode is chosen. + +ISSUES + +* The mode switching depends on the terminal mode set by the inferior +program. Thus ssh/telnet/screen-type programs will typically be in +raw mode, so rlfe won't be much use, even if remote programs run in +canonical mode.
