+This document details the changes between this version, readline-2.2.1,
+and the previous version, readline-2.2.
+
+1. Changes to Readline
+
+a. The `make install' target was corrected so that it did not move the
+ newly-installed libreadline.a to libhistory.old
+
+b. The `make install' target for the documentation will now install the
+ info files from the source directory if they do not appear in the
+ build directory, since they are shipped in the readline tar file.
+
+c. Fixed a problem with redisplay that showed up when the prompt string was
+ longer than the screen width and the prompt contained invisible characters.
+
+d. Fixed a problem with the paren matching code -- the blink was far too
+ short (it's specified in microseconds, not milliseconds, Chet!).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, readline-2.2,
+and the previous version, readline-2.1.
+
+1. Changes to Readline
+
+a. Added a missing `extern' to a declaration in readline.h that kept
+ readline from compiling cleanly on some systems.
+
+b. The history file is now opened with mode 0600 when it is written for
+ better security.
+
+c. Changes were made to the SIGWINCH handling code so that prompt redisplay
+ is done better.
+
+d. ^G now interrupts incremental searches correctly.
+
+e. A bug that caused a core dump when the set of characters to be quoted
+ when completing words was empty was fixed.
+
+f. Fixed a problem in the readline test program rltest.c that caused a core
+ dump.
+
+g. The code that handles parser directives in inputrc files now displays
+ more error messages.
+
+h. The history expansion code was fixed so that the appearance of the
+ history comment character at the beginning of a word inhibits history
+ expansion for that word and the rest of the input line.
+
+i. The code that prints completion listings now behaves better if one or
+ more of the filenames contains non-printable characters.
+
+j. The time delay when showing matching parentheses is now 0.5 seconds.
+
+
+2. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program 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.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify

+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.
--- /dev/null
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ 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 at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' 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. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+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 supports 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.
+
+ 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' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+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 host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+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.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+Introduction
+============
+
+This is the Gnu Readline library, version 2.2
+
+The Readline library provides a set of functions for use by applications
+that allow users to edit command lines as they are typed in. Both
+Emacs and vi editing modes are available. The Readline library includes
+additional functions to maintain a list of previously-entered command
+lines, to recall and perhaps reedit those lines, and perform csh-like
+history expansion on previous commands.
+
+The history facilites are also placed into a separate library, the
+History library, as part of the build process. The History library
+may be used without Readline in applications which desire its
+capabilities.
+
+The Readline library is free software, distributed under the terms of
+the GNU Public License, version 2. For more information, see the file
+COPYING.
+
+To build the library, try typing `./configure', then `make'. The
+configuration process is automated, so no further intervention should
+be necessary. Readline builds with `gcc' by default if it is
+available. If you want to use `cc' instead, type
+
+ CC=cc ./configure
+
+if you are using a Bourne-style shell. If you are not, the following
+may work:
+
+ env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.
+
+The file rlconf.h contains defines that enable and disable certain
+Readline features.
+
+Examples
+========
+
+There are several example programs that use Readline features in the
+examples directory. The `rl' program is of particular interest. It
+is a command-line interface to Readline, suitable for use in shell
+scripts in place of `read'.
+
+Shared Libraries
+================
+
+There is skeletal support for building shared versions of the
+Readline and History libraries.
+
+Typing `make shared' will cause shared versions of the Readline and
+History libraries to be built on SunOS 4.1.x. For versions of Unix
+other than SunOS, you will have to make some changes to Makefile.in.
+The relevant variables are:
+
+PICFLAG Options to give to the compiler to produce position-independent
+ code. The value `-fpic' works for most versions of gcc.
+SHLIB_OPTS Options to give to the linker to produce a shared library.
+ The value `-assert pure-text -ldl' works on SunOS 4.1.x.
+ The value `-Bshareable' works for some versions of GNU ld.
+
+MAJOR The major version number of the shared library. You should
+ not need to change this.
+MINOR The minor version number of the shared library. Some systems,
+ such as SVR4 and its descendents (e.g., Solaris, Unixware),
+ do not use minor version numbers. For those systems, this
+ variable should be left unset.
+
+LD The linker. The value of `ld' is correct for SunOS 4.1.x.
+ You may need to change it to `gcc'; make sure to change
+ SHLIB_OPTS if you do so.
+
+Once you have edited Makefile.in, type `make Makefile' to rebuild the
+Makefile, then `make shared' to build the shared libraries.
+
+Documentation
+=============
+
+The documentation for the Readline and History libraries appears in the
+`doc' subdirectory. There are two texinfo files and a Unix-style manual
+page describing the programming facilities available in the Readline
+library. The texinfo files include both user and programmer's manuals.
+
+Reporting Bugs
+==============
+
+Bug reports for Readline should be sent to:
+
+ bug-readline@gnu.org
+
+When reporting a bug, please include the following information:
+
+ * the version number and release status of Readline (e.g., 2.2-release)
+ * the machine and OS that it is running on
+ * a list of the compilation flags or the contents of `config.h', if
+ appropriate
+ * a description of the bug
+ * a recipe for recreating the bug reliably
+ * a fix for the bug if you have one!
+
+If you would like to contact the Readline maintainer directly, send mail
+to bash-maintainers@gnu.org.
+
+Since Readline is developed along with bash, the bug-bash@gnu.org mailing
+list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
+Readline bug reports and fixes.

+@chapter Programming with GNU History
+
+This chapter describes how to interface programs that you write
+with the GNU History Library.
+It should be considered a technical guide.
+For information on the interactive use of GNU History, @pxref{Using
+History Interactively}.
+

+@node Introduction to History
+@section Introduction to History
+
+Many programs read input from the user a line at a time. The 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.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries. A history entry is
+declared as follows:
+
+@example
+typedef struct _hist_entry @{
+ char *line;
+ char *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 the current state of the history stuff around. */
+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
+present in GNU History.
+
+@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 ()
+Begin a session in which the history functions might be used. This
+initializes the interactive variables.
+@end deftypefun
+
+@deftypefun {HISTORY_STATE *} history_get_history_state ()
+Return a structure describing the current state of the input history.
+@end deftypefun
+
+@deftypefun void history_set_history_state (HISTORY_STATE *state)
+Set the state of the history list according to @var{state}.
+@end deftypefun
+
+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (char *string)
+Place @var{string} at the end of the history list. The associated data
+field (if any) is set to @code{NULL}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history. The
+removed element is returned so you can free the line, data,
+and containing structure.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} replace_history_entry (int which, char *line, char *data)
+Make the history entry at offset @var{which} have @var{line} and @var{data}.
+This returns the old entry so you can dispose of the data. In the case
+of an invalid @var{which}, a @code{NULL} pointer is returned.
+@end deftypefun
+
+@deftypefun void clear_history ()
+Clear the history list by deleting all the entries.
+@end deftypefun
+
+@deftypefun void stifle_history (int max)
+Stifle the history list, remembering only the last @var{max} entries.
+@end deftypefun
+
+@deftypefun int unstifle_history ()
+Stop stifling the history. This returns the previous amount the
+history was stifled. The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled ()
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+
+@node Information About the History List
+@subsection Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list ()
+Return a @code{NULL} terminated array of @code{HIST_ENTRY} which is the
+current input history. Element 0 of this list is the beginning of time.
+If there is no history, return @code{NULL}.
+@end deftypefun
+
+@deftypefun int where_history ()
+Returns the offset of the current history element.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} current_history ()
+Return the history entry at the current position, as determined by
+@code{where_history ()}. If there is no entry there, return a @code{NULL}
+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}, starting from
+@code{history_base}. If there is no entry there, or if @var{offset}
+is greater than the history length, return a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun int history_total_bytes ()
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+@end deftypefun
+
+@node Moving Around the History List
+@subsection Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+@deftypefun int history_set_pos (int pos)
+Set the position in the history list to @var{pos}, an absolute index
+into the list.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} previous_history ()
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry. If there is no previous entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} next_history ()
+Move the current history offset forward to the next history entry, and
+return the a pointer to that entry. If there is no next entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string. Searching may be performed both forward and backward
+from the current history position. The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset. If @var{direction} < 0, then the search is through previous entries,
+else through subsequent. If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found. Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset. The search is anchored: matching lines must begin with
+@var{string}. If @var{direction} < 0, then the search is through previous
+entries, else through subsequent. If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0.
+Otherwise, nothing is changed, and a -1 is returned.
+@end deftypefun
+
+@deftypefun int history_search_pos (char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list. If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward. Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (char *filename)
+Add the contents of @var{filename} to the history list, a line at a
+time. If @var{filename} is @code{NULL}, then read from
+@file{~/.history}. Returns 0 if successful, or errno if not.
+@end deftypefun
+
+@deftypefun int read_history_range (char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}. If
+@var{from} is zero, start at the beginning. If @var{to} is less than
+@var{from}, then read until the end of the file. If @var{filename} is
+@code{NULL}, then read from @file{~/.history}. Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary. If @var{filename} is
+@code{NULL}, then write the history list to @file{~/.history}. Values
+returned are as in @code{read_history ()}.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+@end deftypefun
+
+@deftypefun int history_truncate_file (char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement @code{csh}-like history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}). Returns:
+@table @code
+@item 0
+If no expansions took place (or, if the only change in
+the text was the de-slashifying of the history expansion
+character);
+@item 1
+if expansions did take place;
+@item -1
+if there was an error in expansion;
+@item 2
+if the returned line should only be displayed, but not executed,
+as with the @code{:p} modifier (@pxref{Modifiers}).
+@end table
+
+If an error ocurred in expansion, then @var{output} contains a descriptive
+error message.
+@end deftypefun
+
+@deftypefun {char *} history_arg_extract (int first, int last, char *string)
+Extract a string segment consisting of the @var{first} through @var{last}
+arguments present in @var{string}. Arguments are broken up as in Bash.
+@end deftypefun
+
+@deftypefun {char *} get_history_event (char *string, int *cindex, int qchar)
+Returns the text of the history event beginning at @var{string} +
+@var{*cindex}. @var{*cindex} is modified to point to after the event
+specifier. At function entry, @var{cindex} points to the index into
+@var{string} where the history event specification begins. @var{qchar}
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+@end deftypefun
+
+@deftypefun {char **} history_tokenize (char *string)
+Return an array of tokens parsed out of @var{string}, much as the
+shell might. The tokens are split on white space and on the
+characters @code{()<>;&|$}, and shell quoting conventions are
+obeyed.
+@end deftypefun
+
+@node History Variables
+@section History Variables
+
+This section describes the externally visible variables exported by
+the GNU History Library.
+
+@deftypevar int history_base
+The logical offset of the first entry in the history list.
+@end deftypevar
+
+@deftypevar int history_length
+The number of entries currently stored in the history list.
+@end deftypevar
+
+@deftypevar int max_input_history
+The maximum number of history entries. This must be changed using
+@code{stifle_history ()}.
+@end deftypevar
+
+@deftypevar char history_expansion_char
+The character that starts a history event. The default is @samp{!}.
+@end deftypevar
+
+@deftypevar char history_subst_char
+The character that invokes word substitution if found at the start of
+a line. The default is @samp{^}.
+@end deftypevar
+
+@deftypevar char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}. The default is whitespace and
+@samp{=}.
+@end deftypevar
+
+@deftypevar {char *} history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to whitespace, @samp{:} and @samp{?} in the case of
+a substring search. The default is empty.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character. The default value is 0.
+@end deftypevar
+
+@deftypevar {Function *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string}) and an integer index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to NULL.

+@cindex command history
+@cindex history list
+
+When the @samp{-o history} option to the @code{set} builtin
+is enabled (@pxref{The Set Builtin}),
+the shell provides access to the @var{command history},
+the list of commands previously typed. The text of the last
+@code{HISTSIZE}
+commands (default 500) is saved in a history list. The shell
+stores each command in the history list prior to parameter and
+variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@code{HISTIGNORE} and @code{HISTCONTROL}.
+When the shell starts up, the history is initialized from the
+file named by the @code{HISTFILE} variable (default @file{~/.bash_history}).
+@code{HISTFILE} is truncated, if necessary, to contain no more than
+the number of lines specified by the value of the @code{HISTFILESIZE}
+variable. When an interactive shell exits, the last
+@code{HISTSIZE} lines are copied from the history list to @code{HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @code{HISTFILE}
+is unset, or if the history file is unwritable, the history is
+not saved. After saving the history, the history file is truncated
+to contain no more than @code{$HISTFILESIZE}
+lines. If @code{HISTFILESIZE} is not set, no truncation is performed.
+
+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 can be used to display or modify the history
+list and manipulate the history file.
+When using the command-line editing, search commands
+are available in each editing mode that provide access to the
+history list.
+
+The shell allows control over which commands are saved on the history
+list. The @code{HISTCONTROL} and @code{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.

+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands that allow you to manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@comment 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 @samp{-l} flag is
+given, the commands are listed on standard output. The @samp{-n} flag
+suppresses the command numbers when listing. The @samp{-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 @code{FCEDIT} variable if set, or the value of the
+@code{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
+@comment btindex history
+@example
+history [-c] [@var{n}]
+history [-anrw] [@var{filename}]
+history -ps @var{arg}
+@end example
+
+Display the history list with line numbers. Lines prefixed with
+with a @samp{*} have been modified. An argument of @var{n} says
+to list only the last @var{n} lines. Options, if supplied, have
+the following meanings:
+
+@table @code
+@item -w
+Write out the current history to the history file.
+
+@item -r
+Read the current history file and append its contents to
+the history list.
+
+@item -a
+Append the new
+history lines (history lines entered since the beginning of the
+current Bash session) to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list. These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -c
+Clear the history list. This may be combined
+with the other options to replace the history list completely.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+@end table
+
+When the @samp{-w}, @samp{-r}, @samp{-a}, or @samp{-n} option is
+used, if @var{filename}
+is given, then it is used as the history file. If not, then
+the value of the @code{HISTFILE} variable is used.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}. 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 @samp{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @samp{-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.

+
+@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{!}
+Start a history substitution, except when followed by a space, tab,
+the end of the line, @samp{=} or @samp{(}.
+
+@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. This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command starting with @var{string}.
+
+@item @code{!?@var{string}[?]}
+Refer to the most recent command containing @var{string}. The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution. Repeat the last command, replacing @var{string1}
+with @var{string2}. Equivalent to
+@code{!!:s/@var{string1}/@var{string2}/}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator. It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}. Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero). Words are
+inserted into the current line separated by single spaces.
+
+@table @code
+
+@item 0 (zero)
+The @code{0}th word. For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The word matched by the most recent @samp{?@var{string}?} search.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th. This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading pathname components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line. Any delimiter may be used in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash. If @samp{&} appears in @var{new},
+it is replaced by @var{old}. A single backslash will quote
+the @samp{&}. The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+Cause changes to be applied over the entire event line. Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.

+.SH DESCRIPTION
+.LP
+.B readline
+will read a line from the terminal
+and return it, using
+.B prompt
+as a prompt. If
+.B prompt
+is null, no prompt is issued. The line returned is allocated with
+.IR malloc (3),
+so the caller must free it when finished. The line returned
+has the final newline removed, so only the text of the line
+remains.
+.LP
+.B readline
+offers editing capabilities while the user is entering the
+line.
+By default, the line editing commands
+are similar to those of emacs.
+A vi\-style line editing interface is also available.
+.SH RETURN VALUE
+.LP
+.B readline
+returns the text of the line read. A blank line
+returns the empty string. If
+.B EOF
+is encountered while reading a line, and the line is empty,
+.B NULL
+is returned. If an
+.B EOF
+is read with a non\-empty line, it is
+treated as a newline.
+.SH NOTATION
+.LP
+An emacs-style notation is used to denote
+keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
+means Control\-N. Similarly,
+.I meta
+keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards
+without a
+.I meta
+key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
+then the
+.I x
+key. This makes ESC the \fImeta prefix\fP.
+The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
+or press the Escape key
+then hold the Control key while pressing the
+.I x
+key.)
+.PP
+Readline commands may be given numeric
+.IR arguments ,
+which normally act as a repeat count. Sometimes, however, it is the
+sign of the argument that is significant. Passing a negative argument
+to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
+causes that command to act in a backward direction. Commands whose
+behavior with arguments deviates from this are noted.
+.PP
+When a command is described as \fIkilling\fP text, the text
+deleted is saved for possible future retrieval
+(\fIyanking\fP). The killed text is saved in a
+\fIkill ring\fP. Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once.
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+.SH INITIALIZATION FILE
+.LP
+Readline is customized by putting commands in an initialization
+file (the \fIinputrc\fP file).
+The name of this file is taken from the value of the
+.B INPUTRC
+environment variable. If that variable is unset, the default is
+.IR ~/.inputrc .
+When a program which uses the readline library starts up, the
+init file is read, and the key bindings and variables are set.
+There are only a few basic constructs allowed in the
+readline init file. Blank lines are ignored.
+Lines beginning with a \fB#\fP are comments.
+Lines beginning with a \fB$\fP indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+Each program using this library may add its own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+into the
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized while
+processing key bindings:
+.IR RUBOUT ,
+.IR DEL ,
+.IR ESC ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR SPC ,
+.IR SPACE ,
+and
+.IR TAB .
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a \fImacro\fP).
+.PP
+.SS Key Bindings
+.PP
+The syntax for controlling key bindings in the
+.I inputrc
+file is simple. All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound. The name may be specified in one of two ways:
+as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
+prefixes, or as a key sequence.
+When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
+.I keyname
+is the name of a key spelled out in English. For example:
+.sp
+.RS
+Control\-u: universal\-argument
+.br
+Meta\-Rubout: backward\-kill\-word
+.br
+Control\-o: ">&output"
+.RE
+.LP
+In the above example,
+.I C\-u
+is bound to the function
+.BR universal\-argument ,
+.I M-DEL
+is bound to the function
+.BR backward\-kill\-word ,
+and
+.I C\-o
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+.I >&output
+into the line).
+.PP
+In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.B keyseq
+differs from
+.B keyname
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes. Some GNU Emacs style key escapes can be
+used, as in the following example.
+.sp
+.RS
+"\eC\-u": universal\-argument
+.br
+"\eC\-x\eC\-r": re\-read\-init\-file
+.br
+"\ee[11~": "Function Key 1"
+.RE
+.PP
+In this example,
+.I C-u
+is again bound to the function
+.BR universal\-argument .
+.I "C-x C-r"
+is bound to the function
+.BR re\-read\-init\-file ,
+and
+.I "ESC [ 1 1 ~"
+is bound to insert the text
+.BR "Function Key 1" .
+The full set of GNU Emacs style escape sequences is
+.RS
+.PD 0
+.TP
+.B \eC\-
+control prefix
+.TP
+.B \eM\-
+meta prefix
+.TP
+.B \ee
+an escape character
+.TP
+.B \e\e
+backslash
+.TP
+.B \e"
+literal "
+.TP
+.B \e'
+literal '
+.RE
+.PD
+.PP
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+.RS
+.PD 0
+.TP
+.B \ea
+alert (bell)
+.TP
+.B \eb
+backspace
+.TP
+.B \ed
+delete
+.TP
+.B \ef
+form feed
+.TP
+.B \en
+newline
+.TP
+.B \er
+carriage return
+.TP
+.B \et
+horizontal tab
+.TP
+.B \ev
+vertical tab
+.TP
+.B \e\fInnn\fP
+the character whose ASCII code is the octal value \fInnn\fP
+(one to three digits)
+.TP
+.B \ex\fInnn\fP
+the character whose ASCII code is the hexadecimal value \fInnn\fP
+(one to three digits)
+.RE
+.PD
+.PP
+When entering the text of a macro, single or double quotes should
+be used to indicate a macro definition. Unquoted text
+is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including " and '.
+.PP
+.B Bash
+allows the current readline key bindings to be displayed or modified
+with the
+.B bind
+builtin command. The editing mode may be switched during interactive
+use by using the
+.B \-o
+option to the
+.B set
+builtin command. Other programs using this library provide
+similar mechanisms. The
+.I inputrc
+file may be edited and re-read if a program does not provide
+any other means to incorporate new bindings.
+.SS Variables
+.PP
+Readline has variables that can be used to further customize its
+behavior. A variable may be set in the
+.I inputrc
+file with a statement of the form
+.RS
+.PP
+\fBset\fP \fIvariable\-name\fP \fIvalue\fP
+.RE
+.PP
+Except where noted, readline variables can take the values
+.B On
+or
+.BR Off .
+The variables and their default values are:
+.PP
+.PD 0
+.TP
+.B bell\-style (audible)
+Controls what happens when readline wants to ring the terminal bell.
+If set to \fBnone\fP, readline never rings the bell. If set to
+\fBvisible\fP, readline uses a visible bell if one is available.
+If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
+.TP
+.B comment\-begin (``#'')
+The string that is inserted in \fBvi\fP mode when the
+.B insert\-comment
+command is executed.
+This command is bound to
+.B M\-#
+in emacs mode and to
+.B #
+in vi command mode.
+.TP
+.B completion\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.TP
+.B completion\-query\-items (100)
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the \fBpossible\-completions\fP command.
+It may be set to any integer value greater than or equal to
+zero. If the number of possible completions is greater than
+or equal to the value of this variable, the user is asked whether
+or not he wishes to view them; otherwise they are simply listed
+on the terminal.
+.TP
+.B convert\-meta (On)
+If set to \fBOn\fP, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prepending an
+escape character (in effect, using escape as the \fImeta prefix\fP).
+.TP
+.B disable\-completion (Off)
+If set to \fBOn\fP, readline will inhibit word completion. Completion
+characters will be inserted into the line as if they had been
+mapped to \fBself-insert\fP.
+.TP
+.B editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to \fIemacs\fP or \fIvi\fP.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.TP
+.B enable\-keypad (Off)
+When set to \fBOn\fP, readline will try to enable the application
+keypad when it is called. Some systems need this to enable the
+arrow keys.
+.TP
+.B expand\-tilde (Off)
+If set to \fBon\fP, tilde expansion is performed when readline
+attempts word completion.
+.TP
+.B horizontal\-scroll\-mode (Off)
+When set to \fBOn\fP, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+.TP
+.B keymap (emacs)
+Set the current readline keymap. The set of legal keymap names is
+\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+vi-command\fP, and
+.IR vi-insert .
+\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
+equivalent to \fIemacs-standard\fP. The default value is
+.IR emacs ;
+the value of
+.B editing\-mode
+also affects the default keymap.
+.TP
+.B mark\-directories (On)
+If set to \fBOn\fP, complete<d directory names have a slash
+appended.
+.TP
+.B mark\-modified\-lines (Off)
+If set to \fBOn\fP, history lines that have been modified are displayed
+with a preceding asterisk (\fB*\fP).
+.TP
+.B meta\-flag (Off)
+If set to \fBOn\fP, readline will enable eight-bit input (that is,
+it will not strip the high bit from the characters it reads),
+regardless of what the terminal claims it can support.
+.TP
+.B output\-meta (Off)
+If set to \fBOn\fP, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+.TP
+.B print\-completions\-horizontally (Off)
+If set to \fBOn\fP, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+.TP
+.B show\-all\-if\-ambiguous (Off)
+This alters the default behavior of the completion functions. If
+set to
+.BR on ,
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+.TP
+.B visible\-stats (Off)
+If set to \fBOn\fP, a character denoting a file's type as reported
+by \fBstat\fP(2) is appended to the filename when listing possible
+completions.
+.PD
+.SS Conditional Constructs
+.PP
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. There are four parser directives used.
+.IP \fB$if\fP
+The
+.B $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline. The text of the test extends to the end of the line;
+no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$if\fP directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the \fBset keymap\fP command, for instance, to set bindings in
+the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
+readline is starting out in emacs mode.
+.IP \fBterm\fP
+The \fBterm=\fP 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
+.B =
+is tested against the full name of the terminal and the portion
+of the terminal name before the first \fB\-\fP. This allows
+.I sun
+to match both
+.I sun
+and
+.IR sun\-cmd ,
+for instance.
+.IP \fBapplication\fP
+The \fBapplication\fP construct is used to include
+application-specific settings. Each program using the readline
+library sets the \fIapplication name\fP, and an initialization
+file 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:
+.sp 1
+.RS
+.nf
+\fB$if\fP bash
+# Quote the current or previous word
+"\eC-xq": "\eeb\e"\eef\e""
+\fB$endif\fP
+.fi
+.RE
+.RE
+.IP \fB$endif\fP
+This command, as seen in the previous example, terminates an
+\fB$if\fP command.
+.IP \fB$else\fP
+Commands in this branch of the \fB$if\fP directive are executed if
+the test fails.
+.IP \fB$include\fP
+This directive takes a single filename as an argument and reads commands
+and bindings from that file. For example, the following directive
+would read \fI/etc/inputrc\fP:
+.sp 1
+.RS
+.nf
+\fB$include\fP \^ \fI/etc/inputrc\fP
+.fi
+.RE
+.SH SEARCHING
+.PP
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:
+.I incremental
+and
+.IR non-incremental .
+.PP
+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.
+The Escape character is used to terminate an incremental search.
+Control-J will also terminate the search.
+Control-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 Control-S or
+Control-R as appropriate.
+This will search backward or forward in the history for the next
+line 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 \fInewline\fP will terminate the search and accept
+the line, thereby executing the command from the history list.
+.PP
+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.
+.SH EDITING COMMANDS
+.PP
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.

+.PD
+.SS Commands for Manipulating the History
+.PP
+.PD 0
+.TP
+.B accept\-line (Newline, Return)
+Accept the line regardless of where the cursor is. If this line is

+Move to the end of the input history, i.e., the line currently being
+entered.
+.TP
+.B reverse\-search\-history (C\-r)
+Search backward starting at the current line and moving `up' through
+the history as necessary. This is an incremental search.
+.TP
+.B forward\-search\-history (C\-s)

+position (the \fIpoint\fP).
+This is a non-incremental search.
+.TP
+.B history\-search\-backward
+Search backward through the history for the string of characters
+between the start of the current line and the point.
+This is a non-incremental search.
+.TP
+.B yank\-nth\-arg (M\-C\-y)
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point (the current
+cursor position). With an argument
+.IR n ,
+insert the \fIn\fPth word from the previous command (the words

+.TP
+.B
+yank\-last\-arg (M\-.\^, M\-_\^)
+Insert the last argument to the previous command (the last word of
+the previous history entry). With an argument,
+behave exactly like \fByank\-nth\-arg\fP.
+Successive calls to \fByank\-last\-arg\fP move back through the history
+list, inserting the last argument of each line in turn.
+.PD
+.SS Commands for Changing Text
+.PP
+.PD 0
+.TP
+.B delete\-char (C\-d)
+Delete the character under the cursor. If point is at the
+beginning of the line, there are no characters in the line, and
+the last character typed was not bound to \fBBdelete\-char\fP, then return
+.SM
+.BR EOF .
+.TP
+.B backward\-delete\-char (Rubout)
+Delete the character behind the cursor. When given a numeric argument,
+save the deleted text on the kill ring.
+.TP
+.B quoted\-insert (C\-q, C\-v)
+Add the next character that you type to the line verbatim. This is
+how to insert characters like \fBC\-q\fP, for example.
+.TP
+.B tab\-insert (M-TAB)
+Insert a tab character.
+.TP
+.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...)
+Insert the character typed.
+.TP
+.B transpose\-chars (C\-t)
+Drag the character before point forward over the character at point.

+.B transpose\-words (M\-t)
+Drag the word behind the cursor past the word in front of the cursor
+moving the cursor over that word as well.
+.TP
+.B upcase\-word (M\-u)
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move point.

+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move point.
+.TP
+.B capitalize\-word (M\-c)
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move point.
+.PD
+.SS Killing and Yanking
+.PP
+.PD 0
+.TP
+.B kill\-line (C\-k)
+Kill the text from the current cursor position to the end of the line.
+.TP
+.B backward\-kill\-line (C\-x Rubout)
+Kill backward to the beginning of the line.
+.TP
+.B unix\-line\-discard (C\-u)
+Kill backward from point to the beginning of the line.
+The killed text is saved on the kill-ring.
+.\" There is no real difference between this and backward-kill-line
+.TP
+.B kill\-whole\-line
+Kill all characters on the current line, no matter where the
+cursor is.
+.TP
+.B kill\-word (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 \fBforward\-word\fP.
+.TP
+.B backward\-kill\-word (M\-Rubout)
+Kill the word behind the cursor. Word boundaries are the same as
+those used by \fBbackward\-word\fP.
+.TP
+.B unix\-word\-rubout (C\-w)
+Kill the word behind the cursor, using white space as a word boundary.
+The word boundaries are different from
+.BR backward\-kill\-word .
+.TP
+.B delete\-horizontal\-space (M\-\e)
+Delete all spaces and tabs around point.
+.TP
+.B kill\-region
+Kill the text between the point and \fImark\fP (saved cursor position).
+This text is referred to as the \fIregion\fP.
+.TP
+.B copy\-region\-as\-kill
+Copy the text in the region to the kill buffer.
+.TP
+.B copy\-backward\-word
+Copy the word before point to the kill buffer.
+The word boundaries are the same as \fBbackward\-word\fP.
+.TP
+.B copy\-forward\-word
+Copy the word following point to the kill buffer.
+The word boundaries are the same as \fBforward\-word\fP.
+.TP
+.B yank (C\-y)
+Yank the top of the kill ring into the buffer at the cursor.
+.TP
+.B yank\-pop (M\-y)
+Rotate the kill ring, and yank the new top. Only works following
+.B yank
+or
+.BR yank\-pop .
+.PD
+.SS Numeric Arguments
+.PP
+.PD 0
+.TP
+.B digit\-argument (M\-0, M\-1, ..., M\-\-)
+Add this digit to the argument already accumulating, or start a new
+argument. M\-\- starts a negative argument.
+.TP
+.B universal\-argument
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing
+.B universal\-argument
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+.PD
+.SS Completing
+.PP
+.PD 0
+.TP
+.B complete (TAB)
+Attempt to perform completion on the text before point.
+The actual completion performed is application-specific.
+.BR Bash ,
+for instance, attempts completion treating the text as a variable
+(if the text begins with \fB$\fP), username (if the text begins with
+\fB~\fP), hostname (if the text begins with \fB@\fP), or
+command (including aliases and functions) in turn. If none
+of these produces a match, filename completion is attempted.
+.BR Gdb ,
+on the other hand,
+allows completion of program functions and variables, and
+only attempts filename completion under certain circumstances.
+.TP
+.B possible\-completions (M\-?)
+List the possible completions of the text before point.
+.TP
+.B insert\-completions (M\-*)
+Insert all completions of the text before point
+that would have been generated by
+\fBpossible\-completions\fP.
+.TP
+.B menu\-complete
+Similar to \fBcomplete\fP, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of \fBmenu\-complete\fP steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung and the
+original text is restored.
+An argument of \fIn\fP moves \fIn\fP positions forward in the list
+of matches; a negative argument may be used to move backward
+through the list.
+This command is intended to be bound to \fBTAB\fP, but is unbound
+by default.
+.PD
+.SS Keyboard Macros
+.PP
+.PD 0
+.TP
+.B start\-kbd\-macro (C\-x (\^)
+Begin saving the characters typed into the current keyboard macro.
+.TP
+.B end\-kbd\-macro (C\-x )\^)

+.BR bell\-style ).
+.TP
+.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...)
+If the metafied character \fIx\fP is lowercase, run the command
+that is bound to the corresponding uppercase character.
+.TP
+.B prefix\-meta (ESC)
+Metafy the next character typed.

+.TP
+.B undo (C\-_, C\-x C\-u)
+Incremental undo, separately remembered for each line.
+.TP
+.B revert\-line (M\-r)
+Undo all changes made to this line. This is like executing the
+.B undo
+command enough times to return the line to its initial state.
+.TP
+.B tilde\-expand (M\-~)
+Perform tilde expansion on the current word.
+.TP
+.B set\-mark (C\-@, M-<space>)
+Set the mark to the current point. If a
+numeric argument is supplied, the mark is set to that position.
+.TP
+.B exchange\-point\-and\-mark (C\-x C\-x)
+Swap the point with the mark. The current cursor position is set to
+the saved position, and the old cursor position is saved as the mark.
+.TP
+.B character\-search (C\-])
+A character is read and point is moved to the next occurrence of that
+character. A negative count searches for previous occurrences.
+.TP
+.B character\-search\-backward (M\-C\-])
+A character is read and point is moved to the previous occurrence of that
+character. A negative count searches for subsequent occurrences.
+.TP
+.B insert\-comment (M\-#)
+The value of the readline
+.B comment\-begin
+variable is inserted at the beginning of the current line, and the line
+is accepted as if a newline had been typed. This makes the current line
+a shell comment.
+.TP
+.B dump\-functions
+Print all of the functions and their key bindings to the
+readline output stream. If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-variables
+Print all of the settable variables and their values to the
+readline output stream. If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-macros
+Print all of the readline key sequences bound to macros and the

+.SH DEFAULT KEY BINDINGS
+.LP
+The following is a list of the default emacs and vi bindings.
+Characters with the 8th bit set are written as M\-<character>, and
+are referred to as
+.I metafied
+characters.
+The printable ASCII characters not mentioned in the list of emacs
+standard bindings are bound to the
+.I self\-insert
+function, which just inserts the given character into the input line.
+In vi insertion mode, all characters not specifically mentioned are
+bound to
+.IR self\-insert .
+Characters assigned to signal generation by
+.IR stty (1)
+or the terminal driver, such as C-Z or C-C,
+retain that function.
+Upper and lower case
+.I metafied
+characters are bound to the same function in the emacs mode
+meta keymap.
+The remaining characters are unbound, which causes readline
+to ring the bell (subject to the setting of the

+@node Programming with GNU Readline
+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the GNU Readline Library and
+other programs. If you are a programmer, and you wish to include the
+features found in GNU Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.
+
+@menu
+* Basic Behavior:: Using the default behavior of Readline.
+* Custom Functions:: Adding your own functions to Readline.
+* Readline Variables:: Variables accessible to custom
+ functions.
+* Readline Convenience Functions:: Functions which Readline supplies to
+ aid in writing your own
+* Custom Completers:: Supplanting or supplementing Readline's
+ completion functions.
+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}. 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 and then reads and returns
+a single line of text from the user. The line @code{readline}
+returns is allocated with @code{malloc ()}; you should @code{free ()}
+the line when you are done with it. The declaration for @code{readline}
+in ANSI C is
+
+@example
+@code{char *readline (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}, int (*@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.
+
+@menu
+* The Function Type:: C declarations to make code readable.
+* Function Writing:: Variables and calling conventions.
+@end menu
+
+@node The Function Type
+@subsection The Function Type
+
+For readabilty, we declare a new type of object, called
+@dfn{Function}. A @code{Function} is a C function which
+returns an @code{int}. The type declaration for @code{Function} is:
+
+@noindent
+@code{typedef int Function ();}
+
+The reason for declaring this new type is to make it easier to write
+code describing pointers to C functions. Let us say we had a variable
+called @var{func} which was a pointer to a function. Instead of the
+classic C declaration
+
+@code{int (*)()func;}
+
+@noindent
+we may write
+
+@code{Function *func;}
+
+@noindent
+Similarly, there are
+
+@example
+typedef void VFunction ();
+typedef char *CPFunction (); @r{and}
+typedef char **CPPFunction ();
+@end example
+
+@noindent
+for functions returning no value, @code{pointer to char}, and
+@code{pointer to pointer to char}, respectively.
+
+@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{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.
+
+@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. You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}. When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The mark (saved position) in the current line. If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read. This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses. This is set from the argument to

+The terminal type, used for initialization.
+@end deftypevar
+
+@deftypevar {char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file

+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+@end deftypevar
+
+@deftypevar {Function *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {Function *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when readline is waiting for terminal input.
+@end deftypevar
+
+@deftypevar {Function *} rl_getc_function
+If non-zero, @code{readline} will call indirectly through this pointer
+to get a character from the input stream. By default, it is set to
+@code{rl_getc}, the default @code{readline} character input function
+(@pxref{Utility Functions}).
+@end deftypevar
+
+@deftypevar {VFunction *} rl_redisplay_function
+If non-zero, @code{readline} will call indirectly through this pointer

+@end menu
+
+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline. This is done by representing the function with a descriptive
+name. The user is able to type the descriptive name when referring to
+the function. Thus, in an init file, one might find
+
+@example
+Meta-Rubout: backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}. You, as the
+programmer, should bind the functions you write to descriptive names as
+well. Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (char *name, Function *function, int key)
+Add @var{name} to the list of named functions. Make @var{function} be
+the function that gets called. If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key ()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications. It is
+the recommended way to add a few functions to the default functions that
+Readline has built in. If you need to do something other
+than adding a function to Readline, you may need to use the
+underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}. The keymap is the
+association between the keys that the user types and the functions that
+get run. You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap ()
+Returns a new, empty keymap. The space for the keymap is allocated with
+@code{malloc ()}; you should @code{free ()} it when you are done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap ()
+Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.
+@end deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with @var{keymap}.
+@end deftypefun
+
+Readline has several internal keymaps. These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap ()
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (char *name)
+Return the keymap matching @var{name}. @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}. @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+You associate keys with functions through the keymap. Readline has
+several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, Function *function)
+Binds @var{key} to @var{function} in the currently active keymap.
+Returns non-zero in the case of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_bind_key_in_map (int key, Function *function, Keymap map)
+Bind @var{key} to @var{function} in @var{map}. Returns non-zero in the case
+of an invalid @var{key}.
+@end deftypefun
+
+@deftypefun int rl_unbind_key (int key)
+Bind @var{key} to the null function in the currently active keymap.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
+Bind @var{key} to the null function in @var{map}.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_function_in_map (Function *function, Keymap map)
+Unbind all keys that execute @var{function} in @var{map}.
+@end deftypefun
+
+@deftypefun int rl_unbind_command_in_map (char *command, Keymap map)
+Unbind all keys that are bound to @var{command} in @var{map}.
+@end deftypefun
+
+@deftypefun int rl_generic_bind (int type, char *keyseq, char *data, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the arbitrary
+pointer @var{data}. @var{type} says what kind of data is pointed to by
+@var{data}; this can be a function (@code{ISFUNC}), a macro
+(@code{ISMACR}), or a keymap (@code{ISKMAP}). This makes new keymaps as
+necessary. The initial keymap in which to do bindings is @var{map}.
+@end deftypefun
+
+@deftypefun int rl_parse_and_bind (char *line)
+Parse @var{line} as if it had been read from the @code{inputrc} file and
+perform any key bindings and variable assignments found
+(@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun int rl_read_init_file (char *filename)
+Read keybindings and variable assignments from @var{filename}
+(@pxref{Readline Init File}).
+@end deftypefun
+
+@node Associating Function Names and Bindings
+@subsection Associating Function Names and Bindings
+
+These functions allow you to find out what keys invoke named functions
+and the functions invoked by a particular key sequence.
+
+@deftypefun {Function *} rl_named_function (char *name)
+Return the function with name @var{name}.
+@end deftypefun
+
+@deftypefun {Function *} rl_function_of_keyseq (char *keyseq, Keymap map, int *type)
+Return the function invoked by @var{keyseq} in keymap @var{map}.
+If @var{map} is NULL, the current keymap is used. If @var{type} is
+not NULL, the type of the object is returned in it (one of @code{ISFUNC},
+@code{ISKMAP}, or @code{ISMACR}).
+@end deftypefun
+
+@deftypefun {char **} rl_invoking_keyseqs (Function *function)
+Return an array of strings representing the key sequences used to
+invoke @var{function} in the current keymap.
+@end deftypefun
+
+@deftypefun {char **} rl_invoking_keyseqs_in_map (Function *function, Keymap map)
+Return an array of strings representing the key sequences used to

+@end deftypefun
+
+@deftypefun void rl_function_dumper (int readable)
+Print the readline function names and the key sequences currently
+bound to them to @code{rl_outstream}. If @var{readable} is non-zero,
+the list is formatted in such a way that it can be made part of an
+@code{inputrc} file and re-read.
+@end deftypefun

+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful. It is certainly easy to try
+something if you know you can undo it. I could use an undo function for
+the stock market.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text ()} or @code{rl_delete_text ()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group ()} and
+@code{rl_end_undo_group ()}.
+
+The types of events that can be undone are:
+
+@example
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @};
+@end example
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text. That is, the undo code
+tells undo what to undo, not how to undo it. @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group ()} and
+@code{rl_end_undo_group ()}.
+
+@deftypefun int rl_begin_undo_group ()
+Begins saving undo information in a group construct. The undo
+information usually comes from calls to @code{rl_insert_text ()} and
+@code{rl_delete_text ()}, but could be the result of calls to
+@code{rl_add_undo ()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group ()
+Closes the current undo group started with @code{rl_begin_undo_group
+()}. There should be one call to @code{rl_end_undo_group ()}
+for each call to @code{rl_begin_undo_group ()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}). The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void free_undo_list ()
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo ()
+Undo the first thing on the undo list. Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying ()}
+once, just before you modify the text. You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a
+single undo unit. It is assumed that you will subsequently modify
+that text.

+@node Alternate Interface
+@subsection Alternate Interface
+
+An alternate interface is available to plain @code{readline()}. Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to @code{select()}
+on various file descriptors. To accomodate this need, readline can
+also be invoked as a `callback' function from an event loop. There
+are functions available to make this easy.
+
+@deftypefun void rl_callback_handler_install (char *prompt, Vfunction *lhandler)
+Set up the terminal for readline I/O and display the initial
+expanded value of @var{prompt}. Save the value of @var{lhandler} to
+use as a callback when a complete line of input has been entered.
+@end deftypefun
+
+@deftypefun void rl_callback_read_char ()
+Whenever an application determines that keyboard input is available, it
+should call @code{rl_callback_read_char()}, which will read the next
+character from the current input source. If that character completes the
+line, @code{rl_callback_read_char} will invoke the @var{lhandler}
+function saved by @code{rl_callback_handler_install} to process the
+line. @code{EOF} is indicated by calling @var{lhandler} with a
+@code{NULL} line.
+@end deftypefun
+
+@deftypefun void rl_callback_handler_remove ()
+Restore the terminal to its initial state and remove the line handler.
+This may be called from within a callback as well as independently.
+@end deftypefun
+
+@subsection An Example
+
+Here is a function which changes lowercase characters to their uppercase
+equivalents, and uppercase characters to lowercase. If
+this function was bound to @samp{M-c}, then typing @samp{M-c} would
+change the case of the character under point. Typing @samp{M-1 0 M-c}
+would change the case of the following 10 characters, leaving the cursor on
+the last character changed.

+
+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available. 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 Readline
+functions intended for interactive use: @var{count} and
+@var{invoking_key}. It isolates the word to be completed and calls
+@code{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{completion_matches ()} uses your
+@dfn{generator} function to generate the list of possible matches, and
+then returns the array of these matches. You should place the address
+of your generator function in @code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{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. When the generator function returns
+@code{(char *)NULL} this signals @code{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.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point. You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{completion_matches ()}). The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {Function *} rl_completion_entry_function
+This is a pointer to the generator function for @code{completion_matches
+()}. If the value of @code{rl_completion_entry_function} is
+@code{(Function *)NULL} then the default filename generator function,
+@code{filename_completion_function ()}, is used.
+@end deftypevar
+
+@node Completion Functions
+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point. @var{what_to_do} says what to do
+with the completion. A value of @samp{?} means list the possible
+completions. @samp{TAB} means do standard completion. @samp{*} means
+insert all of the possible completions. @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point. You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{completion_matches ()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion. This calls @code{rl_complete_internal ()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key))
+List the possible completions. See description of @code{rl_complete
+()}. This calls @code{rl_complete_internal ()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key))
+Insert the list of possible completions into the line, deleting the
+partially-completed word. See description of @code{rl_complete ()}.
+This calls @code{rl_complete_internal ()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun {char **} completion_matches (char *text, CPFunction *entry_func)
+Returns an array of @code{(char *)} which is a list of completions for
+@var{text}. If there are no completions, returns @code{(char **)NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions. The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{(char *)}. The first argument is @var{text}. The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls. @var{entry_func} returns a @code{NULL} pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} filename_completion_function (char *text, int state)
+A generator function for filename completion in the general case. Note
+that completion in Bash is a little different because of all
+the pathnames that must be followed when looking up completions for a
+command. The Bash source is a useful reference for writing custom
+completion functions.
+@end deftypefun
+
+@deftypefun {char *} username_completion_function (char *text, int state)
+A completion generator for usernames. @var{text} contains a partial
+username preceded by a random character (usually @samp{~}). As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {Function *} rl_completion_entry_function
+A pointer to the generator function for @code{completion_matches ()}.
+@code{NULL} means to use @code{filename_entry_function ()}, the default
+filename completer.
+@end deftypevar
+
+@deftypevar {CPPFunction *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} saying
+what the boundaries of @var{text} are. If this function exists and
+returns @code{NULL}, or if this variable is set to @code{NULL}, then
+@code{rl_complete ()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+@end deftypevar
+
+@deftypevar {CPFunction *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an application-
+specific fashion. This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename. The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}. The @var{text}
+is the filename to be quoted. The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}. Some functions use this to decide whether or not to
+insert a closing quote character. The @var{quote_pointer} is a pointer
+to any opening quote character the user typed. Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {CPFunction *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem. It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character
+that delimits the filename (usually @samp{'} or @samp{"}). If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {Function *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling readline uses. The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line. It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call. After that, we ask the user if she is sure
+she wants to see them all. The default value is 100.
+@end deftypevar
+
+@deftypevar {char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine. The default value of this variable is the characters
+which break words for completion in Bash, i.e.,
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {char *} rl_basic_quote_characters
+List of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal ()}. The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {char *} rl_completer_quote_characters
+List of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename. The default is the null string.
+@end deftypevar
+
+@deftypevar {char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text. The
+default is a space character (@samp{ }). Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in custom completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then disallow duplicates in the matches. Default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames. This is @emph{always} zero on entry, and can only be changed
+within a completion entry generator function. If it is set to a non-zero
+value, directory names have a slash appended and Readline attempts to
+quote completed filenames if they contain any embedded word break
+characters.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}. This is @emph{always} non-zero
+on entry, and can only be changed within a completion entry generator
+function. The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibit<ed. The completion
+character will be inserted as any other bound to @code{self-insert}.
+@end deftypevar
+
+@deftypevar {Function *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {Function *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes. It is called with the address of a
+string (the current directory name) as an argument. It could be used
+to expand symbolic links or shell variables in pathnames.

+
+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @key{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @key{M-k} is read as `Meta-K' and describes the character
+produced when the meta key (if you have one) is depressed, and the @key{k}
+key is pressed. If you do not have a meta key, the identical keystroke
+can be generated by typing @key{ESC} @i{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @key{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @key{C-k}.
+
+In addition, several keys have their own names. 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}).
+
+@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{RETURN}. You do not have to be at the
+end of the line to press @key{RETURN}; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+@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 miss typing a character that you wanted to type, and
+not notice your error until you have typed several other characters. In
+that case, you can type @key{C-b} to move the cursor to the left, and then
+correct your mistake. Afterwards, you can move the cursor to the right
+with @key{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 basic bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @key{C-b}
+Move back one character.
+@item @key{C-f}
+Move forward one character.
+@item @key{DEL}
+Delete the character to the left of the cursor.
+@item @key{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @key{C-_}
+Undo the last editing command. You can undo all the way back to an
+empty line.
+@end table
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic possible 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 @key{C-b}, @key{C-f},
+@key{C-d}, and @key{DEL}. Here are some commands for moving more rapidly
+about the line.
+
+@table @key
+@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 @key{C-f} moves forward a character, while @key{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.
+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 @key
+@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.
+
+@item M-DEL
+Kill from the cursor the start of the previous word, or if between
+words, to the start of the previous word.
+
+@item C-w
+Kill from the cursor to the previous whitespace. This is different than
+@key{M-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 @key
+@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 @key{C-y} or @key{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 (@key{-}), 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 @key{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}.
+
+@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: @var{incremental} and @var{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.
+The @key{ESC} character is used to terminate an incremental search.
+@key{C-j} will also terminate the search.
+@key{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 @key{C-s} or
+@key{C-r} 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.
+
+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 @code{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 in his home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @code{INPUTRC}. If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @code{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. Here 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
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@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 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 he wants to see the list of possibilities. 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. 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 ASCII key sequence by stripping the eighth
+bit and prepending 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 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. By default,
+this variable is set to @samp{off}.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command}; @code{emacs} is
+equivalent to @code{emacs-standard}. The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended. The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not strip the eighth bit from the characters it reads),
+regardless of what the terminal claims it can support. The
+default value is @samp{off}. The name @code{meta-flag} is a
+synonym for this variable.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence. The default is @samp{off}.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions. If
+set to @samp{on},
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions. The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple. First you have to know 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 the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command on a line in the init file. The name of the key
+can be expressed in different ways, depending on which is most
+comfortable for you.
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English. For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the above example, @key{C-u} is bound to the function
+@code{universal-argument}, and @key{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes. Some GNU Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+@example
+"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e[11~": "Function Key 1"
+@end example
+
+In the above example, @key{C-u} is bound to the function
+@code{universal-argument} (just as it was in the first example),
+@samp{@key{C-x} @key{C-r}} is bound to the function @code{re-read-init-file},
+and @samp{@key{ESC} @key{[} @key{1} @key{1} @key{~}} is bound to insert
+the text @samp{Function Key 1}.
+
+@end table
+
+The following GNU Emacs style escape sequences are available when
+specifying key sequences:
+
+@table @code
+@item @kbd{\C-}
+control prefix
+@item @kbd{\M-}
+meta prefix
+@item @kbd{\e}
+an escape character
+@item @kbd{\\}
+backslash
+@item @kbd{\"}
+@key{"}
+@item @kbd{\'}
+@key{'}
+@end table
+
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \d
+delete
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \@var{nnn}
+the character whose ASCII code is the octal value @var{nnn}
+(one to three digits)
+@item \x@var{nnn}
+the character whose ASCII code is the hexadecimal value @var{nnn}
+(one to three digits)
+@end table
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including @samp{"} and @samp{'}.
+For example, the following binding will make @samp{C-x \}
+insert a single @samp{\} into the line:
+@example
+"\C-x\\": "\\"
+@end example
+
+@end table
+
+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. 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{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}. This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item application
+The @var{application} construct is used to include
+application-specific settings. Each program using the Readline
+library sets the @var{application name}, and you can test for it.
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$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 $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+@example
+$include /etc/inputrc
+@end example
+@end table
+
+@node Sample Init File
+@subsection Sample Init File

+Here is an example of an inputrc file. This illustrates key
+binding, variable assignment, and conditional syntax.

+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the

+@node Commands For Completion
+@subsection Letting Readline Type For You
+
+@ftable @code
+@item complete (TAB)
+Attempt to do completion on the text before the cursor. This is
+application-specific. Generally, if you are typing a filename
+argument, you can do filename completion; if you are typing a command,
+you can do command completion; if you are typing in a symbol to GDB, you
+can do symbol name completion; if you are typing in a variable to Bash,
+you can do variable name completion, and so on.
+@ifset BashFeatures
+Bash attempts completion treating the text as a variable (if the
+text begins with @samp{$}), username (if the text begins with
+@samp{~}), hostname (if the text begins with @samp{@@}), or
+command (including aliases and functions) in turn. If none
+of these produces a match, filename completion is attempted.
+@end ifset
+
+@item possible-completions (M-?)
+List the possible completions of the text before the cursor.
+
+@item insert-completions (M-*)
+Insert all completions of the text before point that would have
+been generated by @code{possible-completions}.
+
+@item menu-complete ()
+Similar to @code{complete}, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of @code{menu-complete} steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung and the
+original text is restored.
+An argument of @var{n} moves @var{n} positions forward in the list
+of matches; a negative argument may be used to move backward
+through the list.
+This command is intended to be bound to @code{TAB}, but is unbound
+by default.

+@ifset BashFeatures
+@item complete-filename (M-/)
+Attempt filename completion on the text before point.
+
+@item possible-filename-completions (C-x /)

+List the possible completions of the text before point,
+treating it as a hostname.
+
+@item complete-command (M-!)
+Attempt completion on the text before point, treating
+it as a command name. Command completion attempts to
+match the text against aliases, reserved words, shell
+functions, shell builtins, and finally executable filenames,
+in that order.
+
+@item possible-command-completions (C-x !)
+List the possible completions of the text before point,

+the output is formatted in such a way that it can be made part
+of an @var{inputrc} file. This command is unbound by default.
+
+@ifset BashFeatures
+@item glob-expand-word (C-x *)
+The word before point is treated as a pattern for pathname expansion,
+and the list of matching file names is inserted, replacing the word.
+
+@item glob-list-expansions (C-x g)
+The list of expansions that would have been generated by
+@code{glob-expand-word} is displayed, and the line is redrawn.
+
+@item display-shell-version (C-x C-v)
+Display version information about the current instance of Bash.
+
+@item shell-expand-line (M-C-e)
+Expand the line as the shell does.
+This performs alias and history expansion as well as all of the shell
+word expansions (@pxref{Shell Expansions}).
+
+@item history-expand-line (M-^)
+Perform history expansion on the current line.
+
+@item magic-space ()
+Perform history expansion on the current line and insert a space
+(@pxref{History Interaction}).
+
+@item alias-expand-line ()
+Perform alias expansion on the current line (@pxref{Aliases}).
+
+@item history-and-alias-expand-line ()
+Perform history and alias expansion on the current line.
+
+@item insert-last-argument (M-., M-_)
+A synonym for @code{yank-last-arg}.
+
+@item operate-and-get-next (C-o)
+Accept the current line for execution and fetch the next line
+relative to the current line from the history for editing. Any
+argument is ignored.
+
+@item emacs-editing-mode (C-e)
+When in @code{vi} editing mode, this causes a switch back to
+@code{emacs} editing mode, as if the command @samp{set -o emacs} had
+been executed.
+
+@end ifset
+
+@end ftable
+
+@node Readline vi Mode
+@section Readline vi Mode
+
+While the Readline library does not have a full set of @code{vi}
+editing functions, it does contain enough to allow simple editing
+of the line. The Readline @code{vi} mode behaves as specified in
+the @sc{POSIX} 1003.2 standard.
+
+@ifset BashFeatures
+In order to switch interactively between @code{emacs} and @code{vi}
+editing modes, use the @samp{set -o emacs} and @samp{set -o vi}
+commands (@pxref{The Set Builtin}).
+@end ifset
+@ifclear BashFeatures
+In order to switch interactively between @code{emacs} and @code{vi}
+editing modes, use the command M-C-j (toggle-editing-mode).
+@end ifclear
+The Readline default is @code{emacs} mode.
+
+When you enter a line in @code{vi} mode, you are already placed in
+`insertion' mode, as if you had typed an @samp{i}. Pressing @key{ESC}
+switches you into `command' mode, where you can edit the text of the
+line with the standard @code{vi} movement keys, move to previous
+history lines with @samp{k} and subsequent lines with @samp{j}, and
+so forth.

+# In the interest of general portability, some common bourne shell
+# constructs were avoided because they weren't guaranteed to be available
+# in some earlier implementations. I've tried to make this program as
+# portable as possible. Welcome to unix, where the lowest common
+# denominator is rapidly diminishing.
+#
+# Among the more interesting lossages I noticed with some bourne shells
+# are:
+# * No shell functions.
+# * No `unset' builtin.
+# * `shift' cannot take a numeric argument, and signals an error if
+# there are no arguments to shift.
+
+# Code:
+
+# Name by which this script was invoked.

+.SH NAME
+texi2html \- a Texinfo to HTML converter
+.SH SYNOPSIS
+.B texi2html [options] file
+.PP
+.B texi2html -check [-verbose] files
+.SH DESCRIPTION
+.I Texi2html
+converts the given Texinfo file to a set of HTML files. It tries to handle
+most of the Texinfo commands. It creates hypertext links for cross-references,
+footnotes...
+.PP
+It also tries to add links from a reference to its corresponding entry in the
+bibliography (if any). It may also handle a glossary (see the
+.B \-glossary
+option).
+.PP
+.I Texi2html
+creates several files depending on the contents of the Texinfo file and on
+the chosen options (see FILES).
+.PP
+The HTML files created by
+.I texi2html
+are closer to TeX than to Info, that's why
+.I texi2html
+converts @iftex sections and not @ifinfo ones by default. You can reverse
+this with the \-expandinfo option.
+.SH OPTIONS
+.TP 12
+.B \-check
+Check the given file and give the list of all things that may be Texinfo commands.
+This may be used to check the output of
+.I texi2html
+to find the Texinfo commands that have been left in the HTML file.
+.TP
+.B \-expandinfo
+Expand @ifinfo sections, not @iftex ones.
+.TP
+.B \-glossary
+Use the section named 'Glossary' to build a list of terms and put links in the HTML
+document from each term toward its definition.
+.TP
+.B \-invisible \fIname\fP
+Use \fIname\fP to create invisible destination anchors for index links. This is a workaround
+for a known bug of many WWW browsers, including xmosaic.
+.TP
+.B \-I \fIdir\fP
+Look also in \fIdir\fP to find included files.
+.TP
+.B \-menu
+Show the Texinfo menus; by default they are ignored.
+.TP
+.B \-monolithic
+Output only one file, including the table of contents and footnotes.
+.TP
+.B \-number
+Number the sections.
+.TP
+.B \-split_chapter
+Split the output into several HTML files (one per main section:
+chapter, appendix...).
+.TP
+.B \-split_node
+Split the output into several HTML files (one per node).
+.TP
+.B \-usage
+Print usage instructions, listing the current available command-line options.
+.TP
+.B \-verbose
+Give a verbose output. Can be used with the
+.B \-check
+option.
+.PP
+.SH FILES
+By default
+.I texi2html
+creates the following files (foo being the name of the Texinfo file):
+.TP 16
+.B foo_toc.html
+The table of contents.
+.TP
+.B foo.html
+The document's contents.
+.TP
+.B foo_foot.html
+The footnotes (if any).
+.PP
+When used with the
+.B \-split
+option, it creates several files (one per chapter or node), named
+.B foo_n.html
+(n being the indice of the chapter or node), instead of the single
+.B foo.html
+file.
+.PP
+When used with the
+.B \-monolithic
+option, it creates only one file:
+.B foo.html
+.SH VARIABLES
+.I texi2html
+predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
+.SH ADDITIONAL COMMANDS
+.I texi2html
+implements the following non-Texinfo commands:
+.TP 16
+.B @ifhtml
+This indicates the start of an HTML section, this section will passed through
+without any modofication.
+.TP
+.B @end ifhtml
+This indcates the end of an HTML section.
+.SH VERSION
+This is \fItexi2html\fP version 1.51, 09/10/96.
+.PP
+The latest version of \fItexi2html\fP can be found in WWW, cf. URL
+http://wwwcn.cern.ch/dci/texi2html/
