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.
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.)
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.
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.
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
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
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, 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
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
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.

UNMETA to deal with meta characters. Prior to this, we used
numeric values and tests.
* readline.c (rl_complete_internal) Report exactly the number of
possible completions, not the number + 1.
* vi_mode.c (rl_do_move) Do not change the cursor position when
using `cw' or `cW'.

USGr3ness.
* readline.c (rl_unix_word_rubout) As per the "Now REMEMBER"
comment, pass arguments to rl_kill_text () in the correct order to

* history.c (get_history_event) Non-anchored searches can have a
return index of greater than zero from get_history_event ().
Fri Nov 1 07:02:13 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c (rl_translate_keyseq) Make C-? translate to RUBOUT
unconditionally.
Mon Oct 28 11:34:52 1991 Brian Fox (bfox at gnuwest.fsf.org)

* funmap.c; Add entry for call-last-kbd-macro.
* readline.c (rl_prep_term); Use system EOF character on POSIX
systems also.
Thu Oct 3 16:19:53 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c; Make a distinction between having a TERMIOS tty
driver, and having POSIX signal handling. You might one without
the other. New defines used HAVE_POSIX_SIGNALS, and
TERMIOS_TTY_DRIVER.
Tue Jul 30 22:37:26 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: rl_getc () If a call to read () returns without an
error, but with zero characters, the file is empty, so return EOF.
Thu Jul 11 20:58:38 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: (rl_get_next_history, rl_get_previous_history)
Reallocate the buffer space if the line being moved to is longer
the the current space allocated. Amazing that no one has found
this bug until now.
Sun Jul 7 02:37:05 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c:(rl_parse_and_bind) Allow leading whitespace.
Make sure TERMIO and TERMIOS systems treat CR and NL
disctinctly.
Tue Jun 25 04:09:27 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: Rework parsing conditionals to pay attention to the
prior states of the conditional stack. This makes $if statements
work correctly.
Mon Jun 24 20:45:59 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: support for displaying key binding information
includes the functions rl_list_funmap_names (),
invoking_keyseqs_in_map (), rl_invoking_keyseqs (),
rl_dump_functions (), and rl_function_dumper ().
funmap.c: support for same includes rl_funmap_names ().
readline.c, funmap.c: no longer define STATIC_MALLOC. However,
update both version of xrealloc () to handle a null pointer.
Thu Apr 25 12:03:49 1991 Brian Fox (bfox at gnuwest.fsf.org)
* vi_mode.c (rl_vi_fword, fWord, etc. All functions use

Mon Apr 9 19:55:48 1990 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: username_completion_function (); For text passed in
with a leading `~', remember that this could be a filename (after
it is completed).
Thu Apr 5 13:44:24 1990 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: rl_search_history (): Correctly handle case of an
unfound search string, but a graceful exit (as with ESC).
* readline.c: rl_restart_output (); The Apollo passes the address
of the file descriptor to TIOCSTART, not the descriptor itself.
Tue Mar 20 05:38:55 1990 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: rl_complete (); second call in a row causes possible
completions to be listed.
* readline.c: rl_redisplay (), added prompt_this_line variable
which is the first character character following \n in prompt.
Sun Mar 11 04:32:03 1990 Brian Fox (bfox at gnuwest.fsf.org)
* Signals are now supposedly handled inside of SYSV compilation.
Wed Jan 17 19:24:09 1990 Brian Fox (bfox at sbphy.ucsb.edu)
* history.c: history_expand (); fixed overwriting memory error,
added needed argument to call to get_history_event ().
Thu Jan 11 10:54:04 1990 Brian Fox (bfox at sbphy.ucsb.edu)
* readline.c: added mark_modified_lines to control the
display of an asterisk on modified history lines. Also
added a user variable called mark-modified-lines to the
`set' command.
Thu Jan 4 10:38:05 1990 Brian Fox (bfox at sbphy.ucsb.edu)
* readline.c: start_insert (). Only use IC if we don't have an im
capability.
Fri Sep 8 09:00:45 1989 Brian Fox (bfox at aurel)
* readline.c: rl_prep_terminal (). Only turn on 8th bit
as meta-bit iff the terminal is not using parity.
Sun Sep 3 08:57:40 1989 Brian Fox (bfox at aurel)
* readline.c: start_insert (). Uses multiple
insertion call in cases where that makes sense.
rl_insert (). Read type-ahead buffer for additional
keys that are bound to rl_insert, and insert them
all at once. Make insertion of single keys given
with an argument much more efficient.
Tue Aug 8 18:13:57 1989 Brian Fox (bfox at aurel)
* readline.c: Changed handling of EOF. readline () returns
(char *)EOF or consed string. The EOF character is read from the
tty, or if the tty doesn't have one, defaults to C-d.
* readline.c: Added support for event driven programs.
rl_event_hook is the address of a function you want called
while Readline is waiting for input.
* readline.c: Cleanup time. Functions without type declarations
do not use return with a value.
* history.c: history_expand () has new variable which is the
characters to ignore immediately following history_expansion_char.
Sun Jul 16 08:14:00 1989 Brian Fox (bfox at aurel)
* rl_prep_terminal ()
BSD version turns off C-s, C-q, C-y, C-v.
* readline.c -- rl_prep_terminal ()
SYSV version hacks readline_echoing_p.
BSD version turns on passing of the 8th bit for the duration
of reading the line.
Tue Jul 11 06:25:01 1989 Brian Fox (bfox at aurel)
* readline.c: new variable rl_tilde_expander.
If non-null, this contains the address of a function to call if
the standard meaning for expanding a tilde fails. The function is
called with the text sans tilde (as in "foo"), and returns a
malloc()'ed string which is the expansion, or a NULL pointer if
there is no expansion.
* readline.h - new file chardefs.h
Separates things that only readline.c needs from the standard
header file publishing interesting things about readline.
* readline.c:
readline_default_bindings () now looks at terminal chararacters
and binds those as well.
Wed Jun 28 20:20:51 1989 Brian Fox (bfox at aurel)
* Made readline and history into independent libraries.

This is the distribution of the Gnu Readline library. See the file
STANDALONE for a description of the #defines that can be passed via
the makefile to build readline on different systems.
The file rlconf.h contains defines that enable and disable certain
readline features.

This is a description of C preprocessor defines that readline accepts.
Most are passed in from the parent `make'; e.g. from the bash source
directory.
NO_SYS_FILE <sys/file.h> is not present
HAVE_UNISTD_H <unistd.h> exists
HAVE_STDLIB_H <stdlib.h> exists
HAVE_VARARGS_H <varargs.h> exists and is usable
HAVE_STRING_H <string.h> exists
HAVE_ALLOCA_H <alloca.h> exists and is needed for alloca()
HAVE_ALLOCA alloca(3) or a define for it exists
PRAGMA_ALLOCA use of alloca() requires a #pragma, as in AIX 3.x
VOID_SIGHANDLER signal handlers are void functions
HAVE_DIRENT_H <dirent.h> exists and is usable
HAVE_SYS_PTEM_H <sys/ptem.h> exists
HAVE_SYS_PTE_H <sys/pte.h> exists
HAVE_SYS_STREAM_H <sys/stream.h> exists
HAVE_SYS_SELECT_H <sys/select.h> exists
System-specific options:
GWINSZ_IN_SYS_IOCTL need to include <sys/ioctl.h> for TIOCGWINSZ
HAVE_GETPW_DECLS the getpw* functions are declared in <pwd.h> and cannot
be redeclared without compiler errors
HAVE_STRCASECMP the strcasecmp and strncasecmp functions are available

@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.

@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

@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} (@pxref{Korn Shell Builtins})
may be used to list or edit and re-execute a portion of
the history list. The @code{history} builtin (@pxref{C Shell Builtins})
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.

@end ifset
@node History Interaction
@section Interactive 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 previous history 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 previous 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 English (or Unix) words
surrounded by quotes are considered as 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.
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, @key{=} or @key{(}.
@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
can 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{&}.
