It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..312398c --- /dev/null +++ b/Makefile.am @@ -0,0 +1,37 @@ + +AUTOMAKE_OPTIONS = foreign + +SUBDIRS = src examples doc + +EXTRA_DIST = libedit.pc.in +pkgconfigdir = $(libdir)/pkgconfig +pkgconfig_DATA = libedit.pc + +## GENERATED BY SCRIPT - DO NOT EDIT BELOW + +EXTRA_DIST += patches/README \ + patches/00-sys.h.patch \ + patches/01-vis.h.patch \ + patches/02-fgetln.c.patch \ + patches/03-el_term.h.patch \ + patches/04-readline.c.patch \ + patches/05-strlcat.c.patch \ + patches/06-filecomplete.c.patch \ + patches/07-vis.c.patch \ + patches/08-el.h.patch \ + patches/09-history.c.patch \ + patches/10-el.c.patch \ + patches/11-search.c.patch \ + patches/12-unvis.c.patch \ + patches/13-strlcpy.c.patch \ + patches/14-editrc.5.roff.patch \ + patches/15-editline.3.roff.patch \ + patches/cvs_export.sh \ + patches/patches_make.sh \ + patches/patches_apply.sh \ + patches/patches_check.sh \ + patches/extra_dist_list.sh \ + patches/update_version.sh \ + patches/update_dist.sh \ + patches/timestamp.cvsexport + diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..eee61db --- /dev/null +++ b/Makefile.in @@ -0,0 +1,796 @@ +# Makefile.in generated by automake 1.11 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +# 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, +# Inc. +# This Makefile.in is free software;

history and tokenization functions, +similar to those found in +.Xr sh 1 . +.Pp +These functions are available in the +.Nm libedit +library (which needs the +.Nm libcurses +library). +Programs should be linked with +.Fl ledit +.Fl lcurses . +.Sh LINE EDITING FUNCTIONS +The line editing functions use a common data structure, +.Fa EditLine , +which is created by +.Fn el_init +and freed by +.Fn el_end . +.Pp +The following functions are available: +.Bl -tag -width 4n +.It Fn el_init +Initialise the line editor, and return a data structure +to be used by all other line editing functions. +.Fa prog +is the name of the invoking program, used when reading the +.Xr editrc 5 +file to determine which settings to use. +.Fa fin , +.Fa fout +and +.Fa ferr +are the input, output, and error streams (respectively) to use. +In this documentation, references to +.Dq the tty +are actually to this input/output stream combination. +.It Fn el_end +Clean up and finish with +.Fa e , +assumed to have been created with +.Fn el_init . +.It Fn el_reset +Reset the tty and the parser. +This should be called after an error which may have upset the tty's +state. +.It Fn el_gets +Read a line from the tty. +.Fa count +is modified to contain the number of characters read. +Returns the line read if successful, or +.Dv NULL +if no characters were read or if an error occurred. +If an error occurred, +.Fa count

of each line is: +.Dl [prog:]command [arg [...]] +.Pp +.Ar command +is one of the +.Xr editline 3 +builtin commands. +Refer to +.Sx BUILTIN COMMANDS +for more information. +.Pp +.Ar prog +is the program name string that a program defines when it calls +.Xr el_init 3 +to set up +.Xr editline 3 , +which is usually +.Va argv[0] . +.Ar command +will be executed for any program which matches +.Ar prog . +.Pp +.Ar prog +may also be a +.Xr regex 3 +style +regular expression, in which case +.Ar command +will be executed for any program that matches the regular expression. +.Pp +If +.Ar prog +is absent, +.Ar command +is executed for all programs. +.Sh BUILTIN COMMANDS +The +.Nm editline +library has some builtin commands, which affect the way +that the line editing and history functions operate. +These are based on similar named builtins present in the +.Xr tcsh 1 +shell. +.Pp +The following builtin commands are available: +.Bl -tag -width 4n +.It Ic bind Oo Fl a Oc Oo Fl e Oc Oo Fl k Oc Oo Fl l Oc Oo Fl r Oc \ +Oo Fl s Oc Oo Fl v Oc Oo Ar key Op Ar command Oc +Without options, list all bound keys, and the editor command to which +each is bound. +If +.Ar key +is supplied, show the bindings for +.Ar key . +If +.Ar key command +is supplied, bind +.Ar command +to +.Ar key . +Options include: +.Bl -tag -width 4n +.It Fl e +Bind all keys to the standard GNU Emacs-like bindings. +.It Fl v +Bind all keys to the standard +.Xr vi 1 Ns -like +bindings. +.It Fl a +List or change key bindings in the +.Xr vi 1 +mode alternate (command mode) key map. +.It Fl k +.Ar key +is interpreted as a symbolic arrow key name, which may be one of +.Sq up , +.Sq down , +.Sq left +or +.Sq right . +.It Fl l +List all editor commands and a short description of each. +.It Fl r +Remove a key's binding. +.It Fl s +.Ar command +is taken as a literal string and treated as terminal input when +.Ar key +is typed. +Bound keys in +.Ar command +are themselves reinterpreted, and this continues for ten levels of +interpretation. +.El +.Pp +.Ar command +may be one of the commands documented in +.Sx "EDITOR COMMANDS" +below, or another key. +.Pp +.Ar key +and +.Ar command +can contain control characters of the form +.Sm off +.Sq ^character +.Sm on +.Po +e.g. +.Sq ^A +.Pc , +and the following backslashed escape sequences: +.Pp +.Bl -tag -compact -offset indent -width 4n +.It Ic \ea +Bell

echotc Oo Fl sv Oc Ar arg Ar ... +Exercise terminal capabilities given in +.Ar arg Ar ... . +If +.Ar arg +is +.Sq baud , +.Sq cols , +.Sq lines , +.Sq rows , +.Sq meta or +.Sq tabs , +the value of that capability is printed, with +.Dq yes +or +.Dq no +indicating that the terminal does or does not have that capability. +.Pp +.Fl s +returns an empty string for non-existent capabilities, rather than +causing an error. +.Fl v +causes messages to be verbose. +.It Ic edit Op on | off +Enable or disable the +.Nm editline +functionality in a program. +.It Ic history Ar list | Ar size n | Ar unique n +The +.Ar list +command lists all entries in the history. +The +.Ar size +command sets the history size to +.Dv n +entries. +The +.Ar unique +command controls if history should keep duplicate entries. +If +.Dv n +is non zero, only keep unique history entries. +If +.Dv n +is zero, then keep all entries (the default). +.It Ic telltc +List the values of all the terminal capabilities (see +.Xr termcap 5 ) . +.It Ic settc Ar cap Ar val +Set the terminal capability +.Ar cap +to +.Ar val , +as defined in +.Xr termcap 5 . +No sanity checking is done. +.It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q

The + libtool script typically tacks these three numbers onto the end of the name of + the .so file it creates. The formula for calculating the file numbers on Linux + and Solaris is (C - A).(A).(R), so the example given here would create the + file libgrump.so.3.2.1. Other operating systems might use a different library + file name convention; libtool takes care of the details. + + As you release new versions of your library, you will update the library's + C:R:A. Although the rules for changing these version numbers can quickly + become confusing, a few simple tips should help keep you on track. The libtool + documentation goes into greater depth. + + In essence, every time you make a change to the library and release it, the + C:R:A should change. A new library should start with 0:0:0. Each time you + change the public interface (i.e., your installed header files), you should + increment the CURRENT number. This is called your interface number. The main + use of this interface number is to tag successive revisions of your API. + + The AGE number is how many consecutive versions of the API the current + implementation supports. Thus if the CURRENT library API is the sixth + published version of the interface and it is also binary compatible with the + fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When + you break binary compatibility, you need to set AGE to 0 and of course + increment CURRENT. + + The REVISION marks a change in the source code of the library that doesn't + affect the interface-for example, a minor bug fix. Anytime you increment + CURRENT, you should set REVISION back to 0. diff --git a/packaging/cvs_export.sh b/packaging/cvs_export.sh new file mode 100755 index 0000000..7e3fdb7 --- /dev/null +++
