GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 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.
The Free Software Foundation has exempted Bash from the requirement of
Paragraph 2c of the General Public License. This is to say, there is
no requirement for Bash to print a notice when it is started
interactively in the usual way. We made this exception because users
and standards expect shells not to print such messages. This
exception applies to any program that serves as a shell and that is
based primarily on Bash as opposed to other GNU software.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our 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. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, 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 a 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 tell them 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.
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 Agreement 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 work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
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
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual 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 General
Public License.
d) 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.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 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
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying 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.
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.
7. 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 the 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
the license, you may choose any version ever published by the Free Software
Foundation.
8. 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
9. 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.
10. 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 humanity, 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 1, 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) 19xx 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 a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
That's all there is to it!

Sun Dec 29 10:59:00 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c (init_terminal_io) Default to environment variables
LINES and COLUMNS before termcap entry values. If all else fails,
then assume 80x24 terminal.
Sat Dec 28 16:33:11 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: If this machine is USG and it is hpux, then define
USGr3.
* history.c: Cosmetic fixes.
Thu Nov 21 00:10:12 1991 Brian Fox (bfox at gnuwest.fsf.org)
* vi_mode.c: (rl_do_move) Place cursor at end of line, never at
next to last character.
Thu Nov 14 05:08:01 1991 Brian Fox (bfox at gnuwest.fsf.org)
* 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)
* readline.c; Use Posix directory routines and macros.
* 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 $if statements
work correctly.
Mon Jun 24 20:45:59 1991 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c: support for displaying key binding information
includes the functions rl_list_funmap_names (),
invoking_keyseqs_in_map (), rl_invoking_keyseqs (),
rl_dump_functions (), and rl_function_dumper ().
funmap.c: support for same includes rl_funmap_names ().
readline.c, funmap.c: no longer define STATIC_MALLOC. However,
update both version of xrealloc () to handle a null pointer.
Thu Apr 25 12:03:49 1991 Brian Fox (bfox at gnuwest.fsf.org)
* vi_mode.c (rl_vi_fword, fWord, etc. All functions use
the macro `isident()'. Fixed movement bug which prevents
continious movement through the text.
Fri Jul 27 16:47:01 1990 Brian Fox (bfox at gnuwest.fsf.org)
* readline.c (parser_if) Allow "$if term=foo" construct.
Wed May 23 16:10:33 1990 Brian Fox (bfox at gnuwest.fsf.org)

executed. Fixed typo in username_completion_function ().
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.

History Interaction
===================
The History library provides a history expansion feature that is
similar to the history expansion in Csh. The following text describes
the sytax that you use to manipulate the history information.
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 "event", and the portions of that line that are
acted upon are called "words". The line is broken into words in the
same fashion that the Bash shell does, so that several English (or
Unix) words surrounded by quotes are considered as one word.

File: history.info, Node: Event Designators, Next: Word Designators, Up: History Interaction
Event Designators
-----------------
An event designator is a reference to a command line entry in the
history list.
`!'
Start a history subsititution, except when followed by a space,
tab, or the end of the line... = or (.
`!!'
Refer to the previous command. This is a synonym for `!-1'.
`!n'
Refer to command line N.
`!-n'
Refer to the command line N lines back.
`!string'
Refer to the most recent command starting with STRING.
`!?string'[`?']
Refer to the most recent command containing STRING.

File: history.info, Node: Word Designators, Next: Modifiers, Prev: Event Designators, Up: History Interaction
Word Designators
----------------
A : separates the event specification from the word designator. It
can be omitted if the word designator begins with a ^, $, * or %.
Words are numbered from the beginning of the line, with the first word
being denoted by a 0 (zero).
`0 (zero)'
The zero'th word. For many applications, this is the command
word.
`n'
The N'th word.
`^'
The first argument. that is, word 1.
`$'
The last argument.
`%'
The word matched by the most recent `?string?' search.
`x-y'
A range of words; `-Y' Abbreviates `0-Y'.
`*'
All of the words, excepting the zero'th. This is a synonym for
`1-$'. It is not an error to use * if there is just one word in
the event. The empty string is returned in that case.

File: history.info, Node: Modifiers, Prev: Word Designators, Up: History Interaction
Modifiers
---------
After the optional word designator, you can add a sequence of one
or more of the following modifiers, each preceded by a :.
`#'
The entire command line typed so far. This means the current
command, not the previous command, so it really isn't a word
designator, and doesn't belong in this section.
`h'
Remove a trailing pathname component, leaving only the head.
`r'
Remove a trailing suffix of the form `.'SUFFIX, leaving the
basename.
`e'
Remove all but the suffix.
`t'
Remove all leading pathname components, leaving the tail.
`p'
Print the new command but do not execute it.

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 making up new ones.
The programmer using the History library has available to him
functions for remembering lines on a history stack, associating
arbitrary data with a line, removing lines from the stack, searching
through the stack for a line containing an arbitrary text string, and
referencing any line on the stack directly. In addition, a history
"expansion" function is available which provides for a consistent user
interface across many different programs.
The end-user using programs written with the History library has the
benifit 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 used by `Csh'.
If the programmer desires, he can use the Readline library, which
includes some history manipulation by default, and has the added
advantage of Emacs style command line editing.

History Storage
===============
typedef struct _hist_entry {
char *line;
char *data;
} HIST_ENTRY;

File: history.info, Node: History Functions, Next: History Variables, Prev: History Storage, Up: Programming with GNU History
History Functions
=================
This section describes the calling sequence for the various
functions present in GNU History.
* Function: void using_history ()
Begin a session in which the history functions might be used.
This just initializes the interactive variables.
* Function: void add_history (CHAR *STRING)
Place STRING at the end of the history list. The associated data
field (if any) is set to `NULL'.
* Function: int where_history ()
Returns the number which says what history element we are now
looking at.
* Function: int history_set_pos (INT POS)
Set the position in the history list to POS.
* Function: int history_search_pos (CHAR *STRING, INT DIRECTION, INT
POS)
Search for STRING in the history list, starting at POS, an
absolute index into the list. DIRECTION, if negative, says to
search backwards from POS, else forwards. Returns the absolute
index of the history element where STRING was found, or -1
otherwise.
* Function: HIST_ENTRY *remove_history ();
Remove history element WHICH from the history. The removed
element is returned to you so you can free the line, data, and
containing structure.
* Function: void stifle_history (INT MAX)
Stifle the history list, remembering only MAX number of entries.
* Function: int unstifle_history ();
Stop stifling the history. This returns the previous amount the
history was stifled by. The value is positive if the history was
stifled, negative if it wasn't.
* Function: int read_history (CHAR *FILENAME)
Add the contents of FILENAME to the history list, a line at a
time. If FILENAME is `NULL', then read from `~/.history'.
Returns 0 if successful, or errno if not.
* Function: int read_history_range (CHAR *FILENAME, INT FROM, INT TO)
Read a range of lines from FILENAME, adding them to the history
list. Start reading at the FROM'th line and end at the TO'th. If
FROM is zero, start at the beginning. If TO is less than FROM,
then read until the end of the file. If FILENAME is `NULL', then
read from `~/.history'. Returns 0 if successful, or `errno' if
not.
* Function: int write_history (CHAR *FILENAME)
Append the current history to FILENAME. If FILENAME is `NULL',
then append the history list to `~/.history'. Values returned
are as in `read_history ()'.
* Function: int append_history (INT NELEMENTS, CHAR *FILENAME)
Append NELEMENT entries to FILENAME. The entries appended are
from the end of the list minus NELEMENTS up to the end of the
list.
* Function: HIST_ENTRY *replace_history_entry ()
Make the history entry at WHICH have LINE and DATA. This returns
the old entry so you can dispose of the data. In the case of an
invalid WHICH, a `NULL' pointer is returned.
* Function: HIST_ENTRY *current_history ()
Return the history entry at the current position, as determined by
`history_offset'. If there is no entry there, return a `NULL'
pointer.
* Function: HIST_ENTRY *previous_history ()
Back up HISTORY_OFFSET to the previous history entry, and return a
pointer to that entry. If there is no previous entry, return a
`NULL' pointer.
* Function: HIST_ENTRY *next_history ()
Move `history_offset' forward to the next history entry, and
return the a pointer to that entry. If there is no next entry,
return a `NULL' pointer.
* Function: HIST_ENTRY **history_list ()
Return a `NULL' terminated array of `HIST_ENTRY' which is the
current input history. Element 0 of this list is the beginning
of time. If there is no history, return `NULL'.
* Function: int history_search (CHAR *STRING, INT DIRECTION)
Search the history for STRING, starting at `history_offset'. If
DIRECTION < 0, then the search is through previous entries, else
through subsequent. If STRING is found, then `current_history
()' is the history entry, and the value of this function is the
offset in the line of that history entry that the STRING was
found in. Otherwise, nothing is changed, and a -1 is returned.
* Function: int history_expand (CHAR *STRING, CHAR **OUTPUT)
Expand STRING, placing the result into OUTPUT, a pointer to a
string. Returns:
`0'
If no expansions took place (or, if the only change in the
text was the de-slashifying of the history expansion
character),
`1'
if expansions did take place, or
`-1'
if there was an error in expansion.
If an error ocurred in expansion, then OUTPUT contains a
descriptive error message.
* Function: char *history_arg_extract (INT FIRST, INT LAST, CHAR
*STRING)
Extract a string segment consisting of the FIRST through LAST
arguments present in STRING. Arguments are broken up as in the
GNU Bash shell.
* Function: int history_total_bytes ();
Return the number of bytes that the primary history entries are
using. This just adds up the lengths of `the_history->lines'.

File: history.info, Node: History Variables, Next: History Programming Example, Prev: History Functions, Up: Programming with GNU History
History Variables
=================
This section describes the variables in GNU History that are
externally visible.
* Variable: int history_base
For convenience only. You set this when interpreting history
commands. It is the logical offset of the first history element.

File: history.info, Node: History Programming Example, Prev: History Variables, Up: Programming with GNU History
History Programming Example
===========================
The following snippet of code demonstrates simple use of the GNU
History Library.
main ()

int done = 0;
line[0] = 0;
while (!done)

for (i = 0; the_list[i]; i++)
fprintf (stdout, "%d: %s\n",
i + history_base, the_list[i]->line);
}
if (strncmp (line, "delete", strlen ("delete")) == 0)
{
int which;
if ((sscanf (line + strlen ("delete"), "%d", &which)) == 1)
{
HIST_ENTRY *entry = remove_history (which);
if (!entry)
fprintf (stderr, "No such entry %d\n", which);
else
{
free (entry->line);
free (entry);
}
}

fprintf (stderr, "non-numeric arg given to `delete'\n");
}
}

@cindex expansion
The History library provides a history expansion feature that is similar
to the history expansion in Csh. The following text describes the sytax
that you use to manipulate the history information.
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}. The line is broken into words in the same fashion
that the Bash shell does, so that several English (or Unix) words
surrounded by quotes are considered as one word.

Refer to the most recent command containing @var{string}.
@end table
@node Word Designators
@subsection Word Designators
A @key{:} separates the event specification from the word designator. It
can be omitted if the word designator begins with a @key{^}, @key{$},
@key{*} or @key{%}. Words are numbered from the beginning of the line,
with the first word being denoted by a 0 (zero).
@table @code
@item 0 (zero)
The zero'th word. For many applications, this is the command word.
@item 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 @code{?string?} search.
@item x-y
A range of words; @code{-@var{y}} Abbreviates @code{0-@var{y}}.
@item *
All of the words, excepting the zero'th. This is a synonym for @code{1-$}.
It is not an error to use @key{*} if there is just one word in the event.
The empty string is returned in that case.

@node Introduction and Notation
@section Introduction to Line Editing
The following paragraphs describe the notation we use to represent
keystrokes.
The text @key{C-k} is read as `Control-K' and describes the character
produced when the Control key is depressed and the @key{k} key is struck.
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 struck. 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}, for more info).
@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.

* Readline Bare Essentials:: The least you need to know about Readline.
* Readline Movement Commands:: Moving about the input line.
* Readline Killing Commands:: How to delete text, and how to get it back!
* Readline Arguments:: Giving numeric arguments to commands.
@end menu
@node Readline Bare Essentials
@subsection Readline Bare Essentials
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 @key{DEL} 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. Aftwerwards, 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 get `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 get `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 itself into the line at the cursor.
@item @key{C-_}
Undo the last thing that you did. 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.
@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
The act of @dfn{cutting} text means to delete the text from the line, and
to save away the deleted text for later use, just as if you had cut the
text out of the line with a pair of scissors. There is a
@dfn{Killing} text means to delete the text from the line, but to save
it away for later use, usually by @dfn{yanking} 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.
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 fromthe 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
And, here is how to @dfn{yank} the text back into the line. Yanking
is
@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
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 in one clean sweep. 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.
@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 @key{M--} @key{C-k}.
The general way to pass numeric arguments to a command is to type meta
digits before the command. If the first `digit' you type 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 @key{M-1 0 C-d}.
@node Readline Init File
@section Readline Init File
Although the Readline library comes with a set of Emacs-like
keybindings, it is possible that you would like to use a different set
of keybindings. You can customize programs that use Readline by putting
commands in an @dfn{init} file in your home directory. The name of this
file is @file{~/.inputrc}.
When a program which uses the Readline library starts up, the
@file{~/.inputrc} file is read, and the keybindings 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 Syntax:: Syntax for the commands in @file{~/.inputrc}.
* Readline Vi Mode:: Switching to @code{vi} mode in Readline.
@end menu
@node Readline Init Syntax
@subsection Readline Init Syntax
There are only four constructs allowed in the @file{~/.inputrc}
file:
@table @asis
@item Variable Settings
You can change the state of a few variables in Readline. You do this by
using the @code{set} command within the init file. Here is how you
would specify that you wish to use Vi line editing commands:
@example
set editing-mode vi
@end example
Right now, there are only a few variables which can be set; so few in
fact, that we just iterate them here:
@table @code
@item editing-mode
@vindex editing-mode
The @code{editing-mode} variable controls which editing mode you are
using. By default, GNU Readline starts up in Emacs editing mode, where
the keystrokes are most similar to Emacs. This variable can either be
set to @code{emacs} or @code{vi}.
@item horizontal-scroll-mode
@vindex horizontal-scroll-mode
This variable can either be set to @code{On} or @code{Off}. Setting it
to @code{On} means that the text of the lines that you edit will scroll
horizontally on a single screen line when they are larger than the width
of the screen, instead of wrapping onto a new screen line. By default,
this variable is set to @code{Off}.
@item mark-modified-lines
@vindex mark-modified-lines
This variable when set to @code{On}, says to display an asterisk
(@samp{*}) at the starts of history lines which have been modified.
This variable is off by default.
@item prefer-visible-bell
@vindex prefer-visible-bell
If this variable is set to @code{On} it means to use a visible bell if
one is available, rather than simply ringing the terminal bell. By
default, the value is @code{Off}.
@end table
@item Key Bindings
The syntax for controlling keybindings in the @file{~/.inputrc} file is
simple. First you have to know the @i{name} of the command that you
want to change. The following pages contain tables of the command name,
the default keybinding, 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 @file{~/.inputrc} 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, @samp{C-u} is bound to the function
@code{universal-argument}, and @samp{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. Simply place the key sequence
in double quotes. GNU Emacs style key escapes can be used, as in the
following example:
@example
"\C-u": universal-argument
"\C-x\C-r": re-read-init-file
"\e[11~": "Function Key 1"
@end example
In the above example, @samp{C-u} is bound to the function
@code{universal-argument} (just as it was in the first example),
@samp{C-x C-r} is bound to the function @code{re-read-init-file}, and
@samp{ESC [ 1 1 ~} is bound to insert the text @samp{Function Key 1}.

the the history as neccessary.
@end ftable
@node Commands For Text
@subsubsection Commands For Changing Text
@ftable @code
@item delete-char (C-d)
Delete the character under the cursor. If the cursor is at the
beginning of the line, and there are no characters in the line, and
the last character typed was not C-d, then return EOF.
@item backward-delete-char (Rubout)
Delete the character behind the cursor. A numeric arg says to kill
the characters instead of deleting them.
@item quoted-insert (C-q, C-v)
Add the next character that you type to the line verbatim. This is
how to insert things like C-q for example.
@item tab-insert (M-TAB)
Insert a tab character.
@item self-insert (a, b, A, 1, !, ...)
Insert yourself.
@item transpose-chars (C-t)

Point moves forward as well. If point is at the end of the line, then
transpose the two characters before point. Negative args don't work.
@item 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.
@item upcase-word (M-u)
Uppercase the current (or following) word. With a negative argument,
do the previous word, but do not move point.
@item downcase-word (M-l)
Lowercase the current (or following) word. With a negative argument,
do the previous word, but do not move point.
@item capitalize-word (M-c)
Uppercase the current (or following) word. With a negative argument,
do the previous word, but do not move point.

Kill from the cursor to the end of the current word, or if between
words, to the end of the next word.
@item backward-kill-word (M-DEL)
Kill the word behind the cursor.
@item unix-line-discard (C-u)
Do what C-u used to do in Unix line input. We save the killed text on
the kill-ring, though.
@item unix-word-rubout (C-w)
Do what C-w used to do in Unix line input. The killed text is saved
on the kill-ring. This is different than backward-kill-word because
the word boundaries differ.
@item yank (C-y)
Yank the top of the kill ring into the buffer at point.
@item yank-pop (M-y)
Rotate the kill-ring, and yank the new top. You can only do this if
the prior command is yank or yank-pop.

Ding! Stops things.
@item do-uppercase-version (M-a, M-b, ...)
Run the command that is bound to your uppercase brother.
@item prefix-meta (ESC)
Make the next character that you type be metafied. This is for people
without a meta key. Typing @samp{ESC f} is equivalent to typing
@samp{M-f}.
@item undo (C-_)
Incremental undo, separately remembered for each line.
@item revert-line (M-r)
Undo all changes made to this line. This is like typing the `undo'
command enough times to get back to the beginning.
@end ftable
@node Readline Vi Mode
@subsection Readline Vi Mode
While the Readline library does not have a full set of Vi editing
functions, it does contain enough to allow simple editing of the line.
In order to switch interactively between Emacs and Vi editing modes, use
the command M-C-j (toggle-editing-mode).
When you enter a line in Vi mode, you are already placed in `insertion'
mode, as if you had typed an `i'. Pressing @key{ESC} switches you into
`edit' mode, where you can edit the text of the line with the standard
Vi movement keys, move to previous history lines with `k', and following
lines with `j', and so forth.
