Remove libreadline from the source tree, all consumers but gdb

Browse Source 
has been switched to libedit long ago, libreadline was built as an
internallib for a while and kept only for gdbtui which was broken using
libreadline.

Since gdb has been mostly deorbitted in all arches, gdbtui was only installed
on arm and sparc64, given it has been removed, gdb has been switched to use
libedit, no consumers are left for libreadline. Thus this removal

---
Makefile.in
- quote value of ${INSTALL_DATA} when passing it to makes in

doc/Makefile.in
- add a VPATH assignment so the documentation is not remade if it's
already up-to-date in the distribution

they are not found in the current (build) directory -- only an
issue if the libraries are built in a different directory than
the source directory
5/1
---

---
shlib/Makefile.in
- made the suffix rule that creates xx.so from xx.c write the

generated postscript files. Set to 300 because I don't have
any 600-dpi printers

choose to install only the shared libraries. I'm not sure about
the uninstall one yet -- maybe it should check whether or not
the static libraries are installed and not remove the header files
if they are

the minor version number
11/13
-----
examples/rlfe.c
- rlfe can perform filename completion for relative pathnames in the
inferior process's context if the OS supports /proc/PID/cwd (linux
does it OK, Solaris is slightly warped, none of the BSDs have it)

This document details the changes between this version, readline-5.2,
and the previous version, readline-5.1.
1. Changes to Readline
a. Fixed a problem that caused segmentation faults when using readline in
callback mode and typing consecutive DEL characters on an empty line.
b. Fixed several redisplay problems with multibyte characters, all having to
do with the different code paths and variable meanings between single-byte
and multibyte character redisplay.
c. Fixed a problem with key sequence translation when presented with the
sequence \M-\C-x.
d. Fixed a problem that prevented the `a' command in vi mode from being
undone and redone properly.
e. Fixed a problem that prevented empty inserts in vi mode from being undone
properly.
f. Fixed a problem that caused readline to initialize with an incorrect idea
of whether or not the terminal can autowrap.
g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
convert-meta and use \e where appropriate.
h. Changed the default filename completion function to call the filename
dequoting function if the directory completion hook isn't set. This means
that any directory completion hooks need to dequote the directory name,
since application-specific hooks need to know how the word was quoted,
even if no other changes are made.
i. Fixed a bug with creating the prompt for a non-interactive search string
when there are non-printing characters in the primary prompt.
j. Fixed a bug that caused prompts with invisible characters to be redrawn
multiple times in a multibyte locale.
k. Fixed a bug that could cause the key sequence scanning code to return the
wrong function.
l. Fixed a problem with the callback interface that caused it to fail when
using multi-character keyboard macros.
m. Fixed a bug that could cause a core dump when an edited history entry was
re-executed under certain conditions.
n. Fixed a bug that caused readline to reference freed memory when attmpting
to display a portion of the prompt.
o. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
the prompt and input line multiple times.
p. Fixed history expansion to not be confused by here-string redirection.
q. Readline no longer treats read errors by converting them to newlines, as
it does with EOF. This caused partial lines to be returned from readline().
r. Fixed a redisplay bug that occurred in multibyte-capable locales when the
prompt was one character longer than the screen width.
2. New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-5.1,
and the previous version, readline-5.0.
1. Changes to Readline
a. Fixed a bug that caused multiliine prompts to be wrapped and displayed
incorrectly.
b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
line correctly.
c. Fixed a problem in computing the number of invisible characters on the first
line of a prompt whose length exceeds the screen width.
d. Fixed vi-mode searching so that failure preserves the current line rather
than the last line in the history list.
e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at
end-of-line when manipulating multibyte characters.
f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at
end-of-line when manipulating multibyte characters.
g. Fixed multiple bugs in the redisplay of multibyte characters: displaying
prompts longer than the screen width containing multibyte characters,
h. Fix the calculation of the number of physical characters in the prompt
string when it contains multibyte characters.
i. A non-zero value for the `rl_complete_suppress_append' variable now causes
no `/' to be appended to a directory name.
j. Fixed forward-word and backward-word to work when words contained
multibyte characters.
k. Fixed a bug in finding the delimiter of a `?' substring when performing
history expansion in a locale that supports multibyte characters.
l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
of the `convert-meta' variable.
n. Fixed saving and restoring primary prompt when prompting for incremental
and non-incremental searches; search prompts now display multibyte
characters correctly.
o. Fixed a bug that caused keys originally bound to self-insert but shadowed
by a multi-character key sequence to not be inserted.
p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
dereferenced if NULL (matching the documentation).
q. Extensive changes to readline to add enough state so that commands
requiring additional characters (searches, multi-key sequences, numeric
arguments, commands requiring an additional specifier character like
vi-mode change-char, etc.) work without synchronously waiting for
additional input.
r. Lots of changes so readline builds and runs on MinGW.
s. Readline no longer tries to modify the terminal settings when running in
callback mode.
t. The Readline display code no longer sets the location of the last invisible
character in the prompt if the \[\] sequence is empty.
u. The `change-case' command now correctly changes the case of multibyte
characters.
v. Changes to the shared library construction scripts to deal with Windows
DLL naming conventions for Cygwin.
w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
SIGWINCH.
x. Fixed the non-incremental search code in vi mode to dispose of any current
undo list when copying a line from the history into the current editing
buffer.
y. Fixed a bug that caused reversing the incremental search direction to
not work correctly.
z. Fixed the vi-mode `U' command to only undo up to the first time insert mode
was entered, as Posix specifies.
aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
place.
bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
with invisible characters in the prompt in a multibyte locale.
cc. Fixed a bug that could cause the terminal special chars to be bound in the
wrong keymap in vi mode.
2. New Features in Readline
a. The key sequence sent by the keypad `delete' key is now automatically
bound to delete-char.
b. A negative argument to menu-complete now cycles backward through the
completion list.
c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
readline will bind the terminal special characters to their readline
equivalents when it's called (on by default).
d. New bindable command: vi-rubout. Saves deleted text for possible
reinsertion, as with any vi-mode `text modification' command; `X' is bound
to this in vi command mode.
e. If the rl_completion_query_items is set to a value < 0, readline never
asks the user whether or not to view the possible completions.
f. The `C-w' binding in incremental search now understands multibyte
characters.
g. New application-callable auxiliary function, rl_variable_value, returns
a string corresponding to a readline variable's value.
h. When parsing inputrc files and variable binding commands, the parser
strips trailing whitespace from values assigned to boolean variables
before checking them.
i. A new external application-controllable variable that allows the LINES
and COLUMNS environment variables to set the window size regardless of
what the kernel returns.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-5.0,
and the previous version, readline-4.3.
1. Changes to Readline
a. Fixes to avoid core dumps because of null pointer references in the
multibyte character code.
b. Fix to avoid infinite recursion caused by certain key combinations.
c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
d. Readline no longer tries to read ahead more than one line of input, even
when more is available.
e. Fixed the code that adjusts the point to not mishandle null wide
characters.
f. Fixed a bug in the history expansion `g' modifier that caused it to skip
every other match.
g. Fixed a bug that caused the prompt to overwrite previous output when the
output doesn't contain a newline and the locale supports multibyte
characters. This same change fixes the problem of readline redisplay
slowing down dramatically as the line gets longer in multibyte locales.
h. History traversal with arrow keys in vi insertion mode causes the cursor
to be placed at the end of the new line, like in emacs mode.
i. The locale initialization code does a better job of using the right
precedence and defaulting when checking the appropriate environment
variables.
j. Fixed the history word tokenizer to handle <( and >( better when used as
part of bash.
k. The overwrite mode code received several bug fixes to improve undo.
l. Many speedups to the multibyte character redisplay code.
m. The callback character reading interface should not hang waiting to read
keyboard input.
n. Fixed a bug with redoing vi-mode `s' command.
o. The code that initializes the terminal tracks changes made to the terminal
special characters with stty(1) (or equivalent), so that these changes
are reflected in the readline bindings. New application-callable function
to make it work: rl_tty_unset_default_bindings().
p. Fixed a bug that could cause garbage to be inserted in the buffer when
changing character case in vi mode when using a multibyte locale.
q. Fixed a bug in the redisplay code that caused problems on systems
supporting multibyte characters when moving between history lines when the
new line has more glyphs but fewer bytes.
r. Undo and redo now work better after exiting vi insertion mode.
s. Make sure system calls are restarted after a SIGWINCH is received using
SA_RESTART.
t. Improvements to the code that displays possible completions when using
multibyte characters.
u. Fixed a problem when parsing nested if statements in inputrc files.
v. The completer now takes multibyte characters into account when looking for
quoted substrings on which to perform completion.
w. The history search functions now perform better bounds checking on the
history list.
x. Change to history expansion functions to treat `^' as equivalent to word
one, as the documention states.
y. Some changes to the display code to improve display and redisplay of
multibyte characters.
z. Changes to speed up the multibyte character redisplay code.
aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
last character of a word if invoked while point was on the word's
next-to-last character.
bb. Fixed a bug that could cause incorrect filename quoting when
case-insensitive completion was enabled and the word being completed
contained backslashes quoting word break characters.
cc. Fixed a bug in redisplay triggered when the prompt string contains
invisible characters.
dd. Fixed some display (and other) bugs encountered in multibyte locales
when a non-ascii character was the last character on a line.
ee. Fixed some display bugs caused by multibyte characters in prompt strings.
ff. Fixed a problem with history expansion caused by non-whitespace characters
used as history word delimiters.
gg. Fixed a problem that could cause readline to refer to freed memory when
moving between history lines while doing searches.
hh. Improvements to the code that expands and displays prompt strings
containing multibyte characters.
ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
to the last `c'hange command for later use with `.'.
jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work
incorrectly.
kk. Fixed a problem in vi-mode that caused the last text modification command
to not be remembered across different command lines.
ll. Fixed problems with changing characters and changing case at the end of
the line.
mm. Fixed a problem with readline saving the contents of the current line
before beginning a non-interactive search.
nn. Fixed a problem with EOF detection when using rl_event_hook.
oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
arguments.
2. New Features in Readline
a. History expansion has a new `a' modifier equivalent to the `g' modifier
for compatibility with the BSD csh.
b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
modifier, which performs a substitution once per word.
c. All non-incremental search operations may now undo the operation of
replacing the current line with the history line.
d. The text inserted by an `a' command in vi mode can be reinserted with
`.'.
e. New bindable variable, `show-all-if-unmodified'. If set, the readline
completer will list possible completions immediately if there is more
than one completion and partial completion cannot be performed.
f. There is a new application-callable `free_history_entry()' function.
g. History list entries now contain timestamp information; the history file
functions know how to read and write timestamp information associated
with each entry.
h. Four new key binding functions have been added:
rl_bind_key_if_unbound()
rl_bind_key_if_unbound_in_map()
rl_bind_keyseq_if_unbound()
rl_bind_keyseq_if_unbound_in_map()
i. New application variable, rl_completion_quote_character, set to any
quote character readline finds before it calls the application completion
function.
j. New application variable, rl_completion_suppress_quote, settable by an
application completion function. If set to non-zero, readline does not
attempt to append a closing quote to a completed word.
k. New application variable, rl_completion_found_quote, set to a non-zero
value if readline determines that the word to be completed is quoted.
Set before readline calls any application completion function.
l. New function hook, rl_completion_word_break_hook, called when readline
needs to break a line into words when completion is attempted. Allows
the word break characters to vary based on position in the line.
m. New bindable command: unix-filename-rubout. Does the same thing as
unix-word-rubout, but adds `/' to the set of word delimiters.
n. When listing completions, directories have a `/' appended if the
`mark-directories' option has been enabled.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.3,
and the previous version, readline-4.2a.
1. Changes to Readline
a. Fixed output of comment-begin character when listing variable values.
b. Added some default key bindings for common escape sequences produced by
HOME and END keys.
c. Fixed the mark handling code to be more emacs-compatible.
d. A bug was fixed in the code that prints possible completions to keep it
from printing empty strings in certain circumstances.
e. Change the key sequence printing code to print ESC as M\- if ESC is a
meta-prefix character -- it's easier for users to understand than \e.
f. Fixed unstifle_history() to return values that match the documentation.
g. Fixed the event loop (rl_event_hook) to handle the case where the input
file descriptor is invalidated.
h. Fixed the prompt display code to work better when the application has a
custom redisplay function.
i. Changes to make reading and writing the history file a little faster, and
to cope with huge history files without calling abort(3) from xmalloc.
j. The vi-mode `S' and `s' commands are now undone correctly.
k. Fixed a problem which caused the display to be messed up when the last
line of a multi-line prompt (possibly containing invisible characters)
was longer than the screen width.
2. New Features in Readline
a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
be bound to readline functions. Now the arrow keys may be used in vi
insert mode.
b. When listing completions, and the number of lines displayed is more than
the screen length, readline uses an internal pager to display the results.
This is controlled by the `page-completions' variable (default on).
c. New code to handle editing and displaying multibyte characters.
d. The behavior introduced in bash-2.05a of deciding whether or not to
append a slash to a completed name that is a symlink to a directory has
been made optional, controlled by the `mark-symlinked-directories'
variable (default is the 2.05a behavior).
e. The `insert-comment' command now acts as a toggle if given a numeric
argument: if the first characters on the line don't specify a
comment, insert one; if they do, delete the comment text
f. New application-settable completion variable:
rl_completion_mark_symlink_dirs, allows an application's completion
function to temporarily override the user's preference for appending
slashes to names which are symlinks to directories.
g. New function available to application completion functions:
rl_completion_mode, to tell how the completion function was invoked
and decide which argument to supply to rl_complete_internal (to list
completions, etc.).
h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
bindable command, which could be bound to `Insert'.
i. New application-settable completion variable:
rl_completion_suppress_append, inhibits appending of
rl_completion_append_character to completed words.
j. New key bindings when reading an incremental search string: ^W yanks
the currently-matched word out of the current line into the search
string; ^Y yanks the rest of the current line into the search string,
DEL or ^H deletes characters from the search string.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.2a,
and the previous version, readline-4.2.
1. Changes to Readline
a. More `const' and type casting fixes.
b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
overflow problems.
c. The completion code no longer appends a `/' or ` ' to a match when
completing a symbolic link that resolves to a directory name, unless
the match does not add anything to the word being completed. This
means that a tab will complete the word up to the full name, but not
add anything, and a subsequent tab will add a slash.
d. Fixed a trivial typo that made the vi-mode `dT' command not work.
e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
f. Fixed the tty code so that ^V works more than once.
g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
because the use of __P in typedefs conflicted g++ and glibc.
h. The completion code now attempts to do a better job of preserving the
case of the word the user typed if ignoring case in completions.
i. Readline defaults to not echoing the input and lets the terminal
initialization code enable echoing if there is a controlling terminal.
j. The key binding code now processes only two hex digits after a `\x'
escape sequence, and the documentation was changed to note that the
octal and hex escape sequences result in an eight-bit value rather
than strict ASCII.
k. Fixed a few places where negative array subscripts could have occurred.
l. Fixed the vi-mode code to use a better method to determine the bounds of
the array used to hold the marks, and to avoid out-of-bounds references.
m. Fixed the defines in chardefs.h to work better when chars are signed.
n. Fixed configure.in to use the new names for bash autoconf macros.
o. Readline no longer attempts to define its own versions of some ctype
macros if they are implemented as functions in libc but not as macros in
<ctype.h>.
p. Fixed a problem where rl_backward could possibly set point to before
the beginning of the line.
q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
include file problems.
2. New Features in Readline
a. Added extern declaration for rl_get_termcap to readline.h, making it a
public function (it was always there, just not in readline.h).
b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
d. New bindable boolean readline variable: match-hidden-files. Controls
completion of files beginning with a `.' (on Unix). Enabled by default.
e. The history expansion code now allows any character to terminate a
`:first-' modifier, like csh.
f. The incremental search code remembers the last search string and uses
it if ^R^R is typed without a search string.
h. New bindable variable `history-preserve-point'. If set, the history
code attempts to place the user at the same location on each history
line retrived with previous-history or next-history.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.2,
and the previous version, readline-4.1.
1. Changes to Readline
a. When setting the terminal attributes on systems using `struct termio',
readline waits for output to drain before changing the attributes.
b. A fix was made to the history word tokenization code to avoid attempts to
dereference a null pointer.
c. Readline now defaults rl_terminal_name to $TERM if the calling application
has left it unset, and tries to initialize with the resultant value.
d. Instead of calling (*rl_getc_function)() directly to get input in certain
places, readline now calls rl_read_key() consistently.
e. Fixed a bug in the completion code that allowed a backslash to quote a
single quote inside a single-quoted string.
f. rl_prompt is no longer assigned directly from the argument to readline(),
but uses memory allocated by readline. This allows constant strings to
be passed to readline without problems arising when the prompt processing
code wants to modify the string.
g. Fixed a bug that caused non-interactive history searches to return the
wrong line when performing multiple searches backward for the same string.
h. Many variables, function arguments, and function return values are now
declared `const' where appropriate, to improve behavior when linking with
C++ code.
i. The control character detection code now works better on systems where
`char' is unsigned by default.
j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
replaced with a set of specific prototyped typedefs, though they are
still in the readline header files for backwards compatibility.
m. Nearly all of the (undocumented) internal global variables in the library
now have an _rl_ prefix -- there were a number that did not, like
screenheight, screenwidth, alphabetic, etc.
n. The ding() convenience function has been renamed to rl_ding(), though the
old function is still defined for backwards compatibility.
o. The completion convenience functions filename_completion_function,
username_completion_function, and completion_matches now have an rl_
prefix, though the old names are still defined for backwards compatibility.
p. The functions shared by readline and bash (linkage is satisfied from bash
when compiling with bash, and internally otherwise) now have an sh_ prefix.
q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
that the `soname' contains only the major version number rather than the
major and minor numbers.
r. Fixed a redisplay bug that occurred when the prompt spanned more than one
physical line and contained invisible characters.
s. Added a missing `includedir' variable to the Makefile.
t. When installing the shared libraries, make sure symbolic links are relative.
u. Added configure test so that it can set `${MAKE}' appropriately.
v. Fixed a bug in rl_forward that could cause the point to be set to before
the beginning of the line in vi mode.
w. Fixed a bug in the callback read-char interface to make it work when a
readline function pushes some input onto the input stream with
rl_execute_next (like the incremental search functions).
x. Fixed a file descriptor leak in the history file manipulation code that
was tripped when attempting to truncate a non-regular file (like
/dev/null).
y. Changes to make all of the exported readline functions declared in
readline.h have an rl_ prefix (rltty_set_default_bindings is now
rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
z. The formatted documentation included in the base readline distribution
is no longer removed on a `make distclean'.
aa. Some changes were made to avoid gcc warnings with -Wall.
bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
`set keymap EMACS' works.
cc. The history file writing and truncation functions now return a useful
status on error.
dd. Fixed a bug that could cause applications to dereference a NULL pointer
if a NULL second argument was passed to history_expand().
ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
value, rl_read_key() now immediately returns '\n' (which is assumed to
be bound to accept-line).
2. New Features in Readline
a. The blink timeout for paren matching is now settable by applications,
via the rl_set_paren_blink_timeout() function.
b. _rl_executing_macro has been renamed to rl_executing_macro, which means
it's now part of the public interface.
c. Readline has a new variable, rl_readline_state, which is a bitmap that
encapsulates the current state of the library; intended for use by
callbacks and hook functions.
d. rlfe has a new -l option to log input and output (-a appends to logfile),
a new -n option to set the readline application name, and -v and -h
options for version and help information.
e. rlfe can now perform filename completion for the inferior process if the
OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
inferior's current working directory.
f. A new file, rltypedefs.h, contains the new typedefs for function pointers
and is installed by `make install'.
g. New application-callable function rl_set_prompt(const char *prompt):
expands its prompt string argument and sets rl_prompt to the result.
h. New application-callable function rl_set_screen_size(int rows, int cols):
public method for applications to set readline's idea of the screen
dimensions.
i. The history example program (examples/histexamp.c) is now built as one
of the examples.
j. The documentation has been updated to cover nearly all of the public
functions and variables declared in readline.h.
k. New function, rl_get_screen_size (int *rows, int *columns), returns
readline's idea of the screen dimensions.
l. The timeout in rl_gather_tyi (readline keyboard input polling function)
is now settable via a function (rl_set_keyboard_input_timeout()).
m. Renamed the max_input_history variable to history_max_entries; the old
variable is maintained for backwards compatibility.
n. The list of characters that separate words for the history tokenizer is
now settable with a variable: history_word_delimiters. The default
value is as before.
o. There is a new history.3 manual page documenting the history library.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.1,
and the previous version, readline-4.0.
1. Changes to Readline
a. Changed the HTML documents so that the table-of-contents is no longer
a separate file.
b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
OSF/1.
c. The shared library major and minor versions are now constructed
automatically by configure and substituted into the makefiles.
d. It's now possible to install the shared libraries separately from the
static libraries.
e. The history library tries to truncate the history file only if it is a
regular file.
f. A bug that caused _rl_dispatch to address negative array indices on
systems with signed chars was fixed.
g. rl-yank-nth-arg now leaves the history position the same as when it was
called.
h. Changes to the completion code to handle MS-DOS drive-letter:pathname
filenames.
i. Completion is now case-insensitive by default on MS-DOS.
j. Fixes to the history file manipulation code for MS-DOS.
k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
l. Some fixes were made to the redisplay code for better operation on MS-DOS.
m. The quoted-insert code will now insert tty special chars like ^C.
n. A bug was fixed that caused the display code to reference memory before
the start of the prompt string.
o. More support for __EMX__ (OS/2).
p. A bug was fixed in readline's signal handling that could cause infinite
recursion in signal handlers.
q. A bug was fixed that caused the point to be less than zero when rl_forward
was given a very large numeric argument.
r. The vi-mode code now gets characters via the application-settable value
of rl_getc_function rather than calling rl_getc directly.
s. The history file code now uses O_BINARY mode when reading and writing
the history file on cygwin32.
t. Fixed a bug in the redisplay code for lines with more than 256 line
breaks.
u. A bug was fixed which caused invisible character markers to not be
stripped from the prompt string if the terminal was in no-echo mode.
v. Readline no longer tries to get the variables it needs for redisplay
from the termcap entry if the calling application has specified its
own redisplay function. Readline treats the terminal as `dumb' in
this case.
w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
sequences is redrawn correctly.
x. Changes to the install and install-shared targets so that the libraries
and header files are installed separately.
2. New Features in Readline
a. A new Readline `user manual' is in doc/rluserman.texinfo.
b. Parentheses matching is now always compiled into readline, and enabled
or disabled when the value of the `blink-matching-paren' variable is
changed.
c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
d. MS-DOS systems now use ~/_history as the default history file.
e. history-search-{forward,backward} now leave the point at the end of the
line when the string to search for is empty, like
{reverse,forward}-search-history.
f. history-search-{forward,backward} now leave the last history line found
in the readline buffer if the second or subsequent search fails.
g. New function for use by applications: rl_on_new_line_with_prompt, used
when an application displays the prompt itself before calling readline().
h. New variable for use by applications: rl_already_prompted. An application
that displays the prompt itself before calling readline() must set this to
a non-zero value.
i. A new variable, rl_gnu_readline_p, always 1. The intent is that an
application can verify whether or not it is linked with the `real'
readline library or some substitute.
j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
is included in the examples subdirectory, though it is not built
by default.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.0,
and the previous version, readline-2.2.
1. Changes to Readline
a. The version number is now 4.0, to match the major and minor version
numbers on the shared readline and history libraries. Future
releases will maintain the identical numbering.
b. Fixed a typo in the `make install' recipe that copied libreadline.a
to libhistory.old right after installing it.
c. The readline and history info files are now installed out of the source
directory if they are not found in the build directory.
d. The library no longer exports a function named `savestring' -- backwards
compatibility be damned.
e. There is no longer any #ifdef SHELL code in the source files.
f. Some changes were made to the key binding code to fix memory leaks and
better support Win32 systems.
g. Fixed a silly typo in the paren matching code -- it's microseconds, not
milliseconds.
h. The readline library should be compilable by C++ compilers.
i. The readline.h public header file now includes function prototypes for
all readline functions, and some changes were made to fix errors in the
source files uncovered by the use of prototypes.
j. The maximum numeric argument is now clamped at 1000000.
k. Fixes to rl_yank_last_arg to make it behave better.
l. Fixed a bug in the display code that caused core dumps if the prompt
string length exceeded 1024 characters.
m. The menu completion code was fixed to properly insert a single completion
if there is only one match.
n. A bug was fixed that caused the display code to improperly display tabs
after newlines.
o. A fix was made to the completion code in which a typo caused the wrong
value to be passed to the function that computed the longest common
prefix of the list of matches.
p. The completion code now checks the value of rl_filename_completion_desired,
which is set by application-supplied completion functions to indicate
that filename completion is being performed, to decide whether or not to
call an application-supplied `ignore completions' function.
q. Code was added to the history library to catch history substitutions
using `&' without a previous history substitution or search having been
performed.
2. New Features in Readline
a. There is a new script, support/shobj-conf, to do system-specific shared
object and library configuration. It generates variables for configure
to substitute into makefiles. The README file provides a detailed
explanation of the shared library creation process.
b. Shared libraries and objects are now built in the `shlib' subdirectory.
There is a shlib/Makefile.in to control the build process. `make shared'
from the top-level directory is still the right way to build shared
versions of the libraries.
c. rlconf.h is now installed, so applications can find out which features
have been compiled into the installed readline and history libraries.
d. rlstdc.h is now an installed header file.
e. Many changes to the signal handling:
o Readline now catches SIGQUIT and cleans up the tty before returning;
o A new variable, rl_catch_signals, is available to application writers
to indicate to readline whether or not it should install its own
signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
SIGTTIN, and SIGTTOU;
o A new variable, rl_catch_sigwinch, is available to application
writers to indicate to readline whether or not it should install its
own signal handler for SIGWINCH, which will chain to the calling
applications's SIGWINCH handler, if one is installed;
o There is a new function, rl_free_line_state, for application signal
handlers to call to free up the state associated with the current
line after receiving a signal;
o There is a new function, rl_cleanup_after_signal, to clean up the
display and terminal state after receiving a signal;
o There is a new function, rl_reset_after_signal, to reinitialize the
terminal and display state after an application signal handler
returns and readline continues
f. There is a new function, rl_resize_terminal, to reset readline's idea of
the screen size after a SIGWINCH.
g. New public functions: rl_save_prompt and rl_restore_prompt. These were
previously private functions with a `_' prefix. These functions are
used when an application wants to write a message to the `message area'
with rl_message and have the prompt restored correctly when the message
is erased.
h. New function hook: rl_pre_input_hook, called just before readline starts
reading input, after initialization.
i. New function hook: rl_display_matches_hook, called when readline would
display the list of completion matches. The new function
rl_display_match_list is what readline uses internally, and is available
for use by application functions called via this hook.
j. New bindable function, delete-char-or-list, like tcsh.
k. A new variable, rl_erase_empty_line, which, if set by an application using
readline, will cause readline to erase, prompt and all, lines on which the
only thing typed was a newline.
l. There is a new script, support/shlib-install, to install and uninstall
the shared readline and history libraries.
m. A new bindable variable, `isearch-terminators', which is a string
containing the set of characters that should terminate an incremental
search without being executed as a command.
n. A new bindable function, forward-backward-delete-char.
-------------------------------------------------------------------------------
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.
59 Temple Place, Suite 330, Boston, MA 02111 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., 59 Temple Place - Suite 330, Boston, MA 02111-1307, 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.

Basic Installation
==================
These are installation instructions for Readline-5.2.
The simplest way to compile readline is:
1. `cd' to the directory containing the readline source code and type
`./configure' to configure readline 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 some time. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile readline and build the static readline
and history libraries. If supported, the shared readline and history
libraries will be built also. See below for instructions on compiling
the other parts of the distribution. Typing `make everything' will
cause the static and shared libraries (if supported) and the example
programs to be built.
3. Type `make install' to install the static readline and history
libraries, the readline include files, the documentation, and, if
supported, the shared readline and history libraries.
4. You can remove the created libraries and object files from the
build directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile readline for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the readline developers, and should be used with care.
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 the build directory,
and Makefiles in the `doc', `shlib', and `examples'
subdirectories. It also creates a `config.h' file 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 readline, please try
to figure out how `configure' could check whether to do them, and
mail diffs or instructions to <bug-readline@gnu.org> 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 readline `configure.in' requires autoconf
version 2.50 or newer.
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 readline 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 readline for one architecture at a
time in the source code directory. After you have installed
readline for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' will install the readline libraries in
`/usr/local/lib', the include files in
`/usr/local/include/readline', the man pages in `/usr/local/man',
and the info files in `/usr/local/info'. You can specify an
installation prefix other than `/usr/local' by giving `configure'
the option `--prefix=PATH' or by supplying a value for the
DESTDIR variable when running `make install'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.
If you give `configure' the option `--exec-prefix=PATH', the
readline Makefiles will use PATH as the prefix for installing the
libraries. Documentation and other data files will still use the
regular prefix.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but need to determine by the type of host readline
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 (e.g., i386-unknown-freebsd4.2).
See the file `config.sub' for the possible values of each field.
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: the readline `configure' looks for a site script, but not
all `configure' scripts do.
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.
Optional Features
=================
The readline `configure' recognizes a single `--with-PACKAGE' option:
`--with-curses'
This tells readline that it can find the termcap library functions
(tgetent, et al.) in the curses library, rather than a separate
termcap library. Readline uses the termcap functions, but does not
link with the termcap or curses library itself, allowing applications
which link with readline the to choose an appropriate library.
This option tells readline to link the example programs with the
curses library rather than libtermcap.
`configure' also recognizes two `--enable-FEATURE' options:
`--enable-shared'
Build the shared libraries by default on supported platforms. The
default is `yes'.
`--enable-static'
Build the static libraries by default. The default is `yes'.
Shared Libraries
================
There is support for building shared versions of the readline and
history libraries. The configure script creates a Makefile in
the `shlib' subdirectory, and typing `make shared' will cause
shared versions of the readline and history libraries to be built
on supported platforms.
If `configure' is given the `--enable-shared' option, it will attempt
to build the shared libraries by default on supported platforms.
Configure calls the script support/shobj-conf to test whether or
not shared library creation is supported and to generate the values
of variables that are substituted into shlib/Makefile. If you
try to build shared libraries on an unsupported platform, `make'
will display a message asking you to update support/shobj-conf for
your platform.
If you need to update support/shobj-conf, you will need to create
a `stanza' for your operating system and compiler. The script uses
the value of host_os and ${CC} as determined by configure. For
instance, FreeBSD 4.2 with any version of gcc is identified as
`freebsd4.2-gcc*'.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
position-independent code. If you are using gcc, this
should probably be set to `-fpic'.
SHOBJ_LD The link editor to be used to create the shared library from
the object files created by $SHOBJ_CC. If you are using
gcc, a value of `gcc' will probably work.
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
If you are using gcc, `-shared' may be all that is necessary.
These should be the flags needed for generic shared object
creation.
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
creation. Many systems use the -R option to the link
editor to embed a path within the library for run-time
library searches. A reasonable value for such systems would
be `-R$(libdir)'.
SHLIB_LIBS Any additional libraries that shared libraries should be
linked against when they are created.
SHLIB_LIBPREF The prefix to use when generating the filename of the shared
library. The default is `lib'; Cygwin uses `cyg'.
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
generating the filename of the shared library. Many systems
use `so'; HP-UX uses `sl'.
SHLIB_LIBVERSION The string to append to the filename to indicate the version
of the shared library. It should begin with $(SHLIB_LIBSUFF),
and possibly include version information that allows the
run-time loader to load the version of the shared library
appropriate for a particular program. Systems using shared
libraries similar to SunOS 4.x use major and minor library
version numbers; for those systems a value of
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
Systems based on System V Release 4 don't use minor version
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
Other Unix versions use different schemes.
SHLIB_DLLVERSION The version number for shared libraries that determines API
compatibility between readline versions and the underlying
system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
can be overridden at configuration time by defining DLLVERSION
in the environment.
SHLIB_DOT The character used to separate the name of the shared library
from the suffix and version information. The default is `.';
systems like Cygwin which don't separate version information
from the library name should set this to the empty string.
SHLIB_STATUS Set this to `supported' when you have defined the other
necessary variables. Make uses this to determine whether
or not shared library creation should be attempted. If
shared libraries are not supported, this will be set to
`unsupported'.
You should look at the existing stanzas in support/shobj-conf for ideas.
Once you have updated support/shobj-conf, re-run configure and type
`make shared' or `make'. The shared libraries will be created in the
shlib subdirectory.
If shared libraries are created, `make install' will install them.
You may install only the shared libraries by running `make
install-shared' from the top-level build directory. Running `make
install' in the shlib subdirectory will also work. If you don't want
to install any created shared libraries, run `make install-static'.

This is a terse description of the new features added to readline-5.2 since
the release of readline-5.1.
1. New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.

Introduction
============
This is the Gnu Readline library, version 5.2.
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] General 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 C preprocessor defines that enable and disable
certain Readline features.
The special make target `everything' will build the static and shared
libraries (if the target platform supports them) and the examples.
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. The configure script creates
a Makefile in the `shlib' subdirectory, and typing `make shared'
will cause shared versions of the Readline and History libraries
to be built on supported platforms.
If `configure' is given the `--enable-shared' option, it will attempt
to build the shared libraries by default on supported platforms.
Configure calls the script support/shobj-conf to test whether or
not shared library creation is supported and to generate the values
of variables that are substituted into shlib/Makefile. If you
try to build shared libraries on an unsupported platform, `make'
will display a message asking you to update support/shobj-conf for
your platform.
If you need to update support/shobj-conf, you will need to create
a `stanza' for your operating system and compiler. The script uses
the value of host_os and ${CC} as determined by configure. For
instance, FreeBSD 4.2 with any version of gcc is identified as
`freebsd4.2-gcc*'.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
position-independent code. If you are using gcc, this
should probably be set to `-fpic'.
SHOBJ_LD The link editor to be used to create the shared library from
the object files created by $SHOBJ_CC. If you are using
gcc, a value of `gcc' will probably work.
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
If you are using gcc, `-shared' may be all that is necessary.
These should be the flags needed for generic shared object
creation.
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
creation. Many systems use the -R option to the link
editor to embed a path within the library for run-time
library searches. A reasonable value for such systems would
be `-R$(libdir)'.
SHLIB_LIBS Any additional libraries that shared libraries should be
linked against when they are created.
SHLIB_LIBPREF The prefix to use when generating the filename of the shared
library. The default is `lib'; Cygwin uses `cyg'.
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
generating the filename of the shared library. Many systems
use `so'; HP-UX uses `sl'.
SHLIB_LIBVERSION The string to append to the filename to indicate the version
of the shared library. It should begin with $(SHLIB_LIBSUFF),
and possibly include version information that allows the
run-time loader to load the version of the shared library
appropriate for a particular program. Systems using shared
libraries similar to SunOS 4.x use major and minor library
version numbers; for those systems a value of
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
Systems based on System V Release 4 don't use minor version
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
Other Unix versions use different schemes.
SHLIB_DLLVERSION The version number for shared libraries that determines API
compatibility between readline versions and the underlying
system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
can be overridden at configuration time by defining DLLVERSION
in the environment.
SHLIB_DOT The character used to separate the name of the shared library
from the suffix and version information. The default is `.';
systems like Cygwin which don't separate version information
from the library name should set this to the empty string.
SHLIB_STATUS Set this to `supported' when you have defined the other
necessary variables. Make uses this to determine whether
or not shared library creation should be attempted.
You should look at the existing stanzas in support/shobj-conf for ideas.
Once you have updated support/shobj-conf, re-run configure and type
`make shared'. The shared libraries will be created in the shlib
subdirectory.
If shared libraries are created, `make install' will install them.
You may install only the shared libraries by running `make
install-shared' from the top-level build directory. Running `make
install' in the shlib subdirectory will also work. If you don't want
to install any created shared libraries, run `make install-static'.
Documentation
=============
The documentation for the Readline and History libraries appears in
the `doc' subdirectory. There are three texinfo files and a
Unix-style manual page describing the facilities available in the
Readline library. The texinfo files include both user and
programmer's manuals. HTML versions of the manuals appear in the
`doc' subdirectory as well.
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., 4.2-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.

Subject: Use of Readline
Reply-to: rms@gnu.org
I think Allbery's suggestion is a good one. So please add this text
in a suitable place. Please don't put it in the GPL itself; that
should be the same as the GPL everywhere else. Putting it in the
README and/or the documentation would be a good idea.
======================================================================
Our position on the use of Readline through a shared-library linking
mechanism is that there is no legal difference between shared-library
linking and static linking--either kind of linking combines various
modules into a single larger work. The conditions for using Readline
in a larger work are stated in section 3 of the GNU GPL.

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

@item
PREAMBLE
The purpose of this License is to make a manual, textbook, or other
functional and useful document @dfn{free} in the sense of freedom: to
assure everyone the effective freedom to copy and redistribute it,
with or without modifying it, either commercially or noncommercially.
Secondarily, this License preserves for the author and publisher a way
to get credit for their work, while not being considered responsible
for modifications made by others.
This License is a kind of ``copyleft'', which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft
license designed for free software.
We have designed this License in order to use it for manuals for free
software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals;
it can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License
principally for works whose purpose is instruction or reference.
@item
APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be
distributed under the terms of this License. Such a notice grants a
world-wide, royalty-free license, unlimited in duration, to use that
work under the conditions stated herein. The ``Document'', below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as ``you''. You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
A ``Modified Version'' of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
A ``Secondary Section'' is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall
subject (or to related matters) and contains nothing that could fall
directly within that overall subject. (Thus, if the Document is in
part a textbook of mathematics, a Secondary Section may not explain
any mathematics.) The relationship could be a matter of historical
connection with the subject or with related matters, or of legal,
commercial, philosophical, ethical or political position regarding
them.
The ``Invariant Sections'' are certain Secondary Sections whose titles
are designated, as being those of Invariant Sections, in the notice
that says that the Document is released under this License. If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero
Invariant Sections. If the Document does not identify any Invariant
Sections then there are none.
The ``Cover Texts'' are certain short passages of text that are listed,
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
the Document is released under this License. A Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
A ``Transparent'' copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or
for automatic translation to a variety of formats suitable for input
to text formatters. A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text. A copy that is not ``Transparent'' is called ``Opaque''.
Examples of suitable formats for Transparent copies include plain
@sc{ascii} without markup, Texinfo input format, La@TeX{} input
format, @acronym{SGML} or @acronym{XML} using a publicly available
@acronym{DTD}, and standard-conforming simple @acronym{HTML},
PostScript or @acronym{PDF} designed for human modification. Examples
of transparent image formats include @acronym{PNG}, @acronym{XCF} and
@acronym{JPG}. Opaque formats include proprietary formats that can be
read and edited only by proprietary word processors, @acronym{SGML} or
@acronym{XML} for which the @acronym{DTD} and/or processing tools are
not generally available, and the machine-generated @acronym{HTML},
PostScript or @acronym{PDF} produced by some word processors for
output purposes only.
The ``Title Page'' means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page. For works in
formats which do not have any title page as such, ``Title Page'' means
the text near the most prominent appearance of the work's title,
preceding the beginning of the body of the text.
A section ``Entitled XYZ'' means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language. (Here XYZ stands for a
specific section name mentioned below, such as ``Acknowledgements'',
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
of such a section when you modify the Document means that it remains a
section ``Entitled XYZ'' according to this definition.
The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
@item
VERBATIM COPYING
You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies
to the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use
technical measures to obstruct or control the reading or further
copying of the copies you make or distribute. However, you may accept
compensation in exchange for copies. If you distribute a large enough
number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and
you may publicly display copies.
@item
COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have
printed covers) of the Document, numbering more than 100, and the
Document's license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
the back cover. Both covers must also clearly and legibly identify
you as the publisher of these copies. The front cover must present
the full title with all words of the title equally prominent and
visible. You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve
the title of the Document and satisfy these conditions, can be treated
as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.
If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps,
when you begin distribution of Opaque copies in quantity, to ensure
that this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you distribute an
Opaque copy (directly or through your agents or retailers) of that
edition to the public.
It is requested, but not required, that you contact the authors of the
Document well before redistributing any large number of copies, to give
them a chance to provide you with an updated version of the Document.
@item
MODIFICATIONS
You may copy and distribute a Modified Version of the Document under
the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution
and modification of the Modified Version to whoever possesses a copy
of it. In addition, you must do these things in the Modified Version:
@enumerate A
@item
Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
@item
List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
@item
State on the Title page the name of the publisher of the
Modified Version, as the publisher.
@item
Preserve all the copyright notices of the Document.
@item
Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
@item
Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
@item
Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
@item
Include an unaltered copy of this License.
@item
Preserve the section Entitled ``History'', Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section Entitled ``History'' in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
@item
Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on. These may be placed in the ``History'' section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
@item
For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
the Title of the section, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.
@item
Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section titles.
@item
Delete any section Entitled ``Endorsements''. Such a section
may not be included in the Modified Version.
@item
Do not retitle any existing section to be Entitled ``Endorsements'' or
to conflict in title with any Invariant Section.
@item
Preserve any Warranty Disclaimers.
@end enumerate
If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant. To do this, add their titles to the
list of Invariant Sections in the Modified Version's license notice.
These titles must be distinct from any other section titles.
You may add a section Entitled ``Endorsements'', provided it contains
nothing but endorsements of your Modified Version by various
parties---for example, statements of peer review or that the text has
been approved by an organization as the authoritative definition of a
standard.
You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
@item
COMBINING DOCUMENTS
You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled ``History''
in the various original documents, forming one section Entitled
``History''; likewise combine any sections Entitled ``Acknowledgements'',
and any sections Entitled ``Dedications''. You must delete all
sections Entitled ``Endorsements.''
@item
COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
@item
AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an ``aggregate'' if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
@item
TRANSLATION
Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers. In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.
If a section in the Document is Entitled ``Acknowledgements'',
``Dedications'', or ``History'', the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.
@item
TERMINATION
You may not copy, modify, sublicense, or distribute the Document except
as expressly provided for under this License. Any other attempt to
copy, modify, sublicense or distribute the Document is void, and will
automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such
parties remain in full compliance.
@item
FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions
of the GNU Free Documentation License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns. See
@uref{http://www.gnu.org/copyleft/}.
Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License ``or any later version'' applies to it, you have the option of
following the terms and conditions either of that specified version or
of any later version that has been published (not as a draft) by the
Free Software Foundation. If the Document does not specify a version
number of this License, you may choose any version ever published (not
as a draft) by the Free Software Foundation.
@end enumerate
@page
@appendixsubsec ADDENDUM: How to use this License for your documents
To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and
license notices just after the title page:
@smallexample
@group
Copyright (C) @var{year} @var{your name}.
Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.2
or any later version published by the Free Software Foundation;
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
A copy of the license is included in the section entitled ``GNU
Free Documentation License''.
@end group
@end smallexample
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
replace the ``with...Texts.'' line with this:
@smallexample
@group
with the Invariant Sections being @var{list their titles}, with
the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
being @var{list}.
@end group
@end smallexample
If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.
If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License,
to permit their use in free software.

.SH NAME
history \- GNU History Library
.SH COPYRIGHT
.if t The GNU History Library is Copyright \(co 1989-2002 by the Free Software Foundation, Inc.
.if n The GNU History Library is Copyright (C) 1989-2002 by the Free Software Foundation, Inc.
.SH DESCRIPTION
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.
.PP
.SH "HISTORY EXPANSION"
.PP
The history library supports a history expansion feature that
is identical to the history expansion in
.BR bash.
This section describes what syntax features are available.
.PP
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.
.PP
History expansion is usually performed immediately after a complete line
is read.
It takes place in two parts.
The first is to determine which line from the history list
to use during substitution.
The second is to select portions of that line for inclusion into
the current one.
The line selected from the history is the \fIevent\fP,
and the portions of that line that are acted upon are \fIwords\fP.
Various \fImodifiers\fP are available to manipulate the selected words.
The line is broken into words in the same fashion as \fBbash\fP
does when reading input,
so that several words that would otherwise be separated
are considered one word when surrounded by quotes (see the
description of \fBhistory_tokenize()\fP below).
History expansions are introduced by the appearance of the
history expansion character, which is \^\fB!\fP\^ by default.
Only backslash (\^\fB\e\fP\^) and single quotes can quote
the history expansion character.
.SS Event Designators
.PP
An event designator is a reference to a command line entry in the
history list.
.PP
.PD 0
.TP
.B !
Start a history substitution, except when followed by a
.BR blank ,
newline, = or (.
.TP
.B !\fIn\fR
Refer to command line
.IR n .
.TP
.B !\-\fIn\fR
Refer to the current command line minus
.IR n .
.TP
.B !!
Refer to the previous command. This is a synonym for `!\-1'.
.TP
.B !\fIstring\fR
Refer to the most recent command starting with
.IR string .
.TP
.B !?\fIstring\fR\fB[?]\fR
Refer to the most recent command containing
.IR string .
The trailing \fB?\fP may be omitted if
.I string
is followed immediately by a newline.
.TP
.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u
Quick substitution. Repeat the last command, replacing
.I string1
with
.IR string2 .
Equivalent to
``!!:s/\fIstring1\fP/\fIstring2\fP/''
(see \fBModifiers\fP below).
.TP
.B !#
The entire command line typed so far.
.PD
.SS Word Designators
.PP
Word designators are used to select desired words from the event.
A
.B :
separates the event specification from the word designator.
It may be omitted if the word designator begins with a
.BR ^ ,
.BR $ ,
.BR * ,
.BR \- ,
or
.BR % .
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.
.PP
.PD 0
.TP
.B 0 (zero)
The zeroth word. For the shell, this is the command
word.
.TP
.I n
The \fIn\fRth word.
.TP
.B ^
The first argument. That is, word 1.
.TP
.B $
The last argument.
.TP
.B %
The word matched by the most recent `?\fIstring\fR?' search.
.TP
.I x\fB\-\fPy
A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'.
.TP
.B *
All of the words but the zeroth. This is a synonym
for `\fI1\-$\fP'. It is not an error to use
.B *
if there is just one
word in the event; the empty string is returned in that case.
.TP
.B x*
Abbreviates \fIx\-$\fP.
.TP
.B x\-
Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word.
.PD
.PP
If a word designator is supplied without an event specification, the
previous command is used as the event.
.SS Modifiers
.PP
After the optional word designator, there may appear a sequence of
one or more of the following modifiers, each preceded by a `:'.
.PP
.PD 0
.PP
.TP
.B h
Remove a trailing file name component, leaving only the head.
.TP
.B t
Remove all leading file name components, leaving the tail.
.TP
.B r
Remove a trailing suffix of the form \fI.xxx\fP, leaving the
basename.
.TP
.B e
Remove all but the trailing suffix.

.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
This section describes how to use the History library in other programs.
.SS Introduction to History
.PP
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 \fIexpansion\fP function
is available which provides for a consistent user interface across
different programs.
.PP
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
identical to
the history substitution provided by \fBbash\fP.
.PP
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.
.PP
Before declaring any functions using any functionality the History
library provides in other code, an application writer should include
the file
.FN <readline/history.h>
in any file that uses the
History library's features. It supplies extern declarations for all
of the library's public functions and variables, and declares all of
the public data structures.
.SS History Storage
.PP
The history list is an array of history entries. A history entry is
declared as follows:
.PP
.Vb "typedef void *" histdata_t;
.PP
.nf
typedef struct _hist_entry {
char *line;
char *timestamp;
histdata_t data;
} HIST_ENTRY;
.fi
.PP
The history list itself might therefore be declared as
.PP
.Vb "HIST_ENTRY **" the_history_list;
.PP
The state of the History library is encapsulated into a single structure:
.PP
.nf
/*
* A structure used to pass around the current state of the history.
*/
typedef struct _hist_state {
HIST_ENTRY **entries; /* Pointer to the entries themselves. */
int offset; /* The location pointer within this array. */
int length; /* Number of elements within this array. */
int size; /* Number of slots allocated to this array. */
int flags;
} HISTORY_STATE;
.fi
.PP
If the flags member includes \fBHS_STIFLED\fP, the history has been
stifled.
.SH "History Functions"
.PP
This section describes the calling sequence for the various functions
exported by the GNU History library.
.SS 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.
.Fn1 void using_history void
Begin a session in which the history functions might be used. This
initializes the interactive variables.
.Fn1 "HISTORY_STATE *" history_get_history_state void
Return a structure describing the current state of the input history.
.Fn1 void history_set_history_state "HISTORY_STATE *state"

.SS History List Management
These functions manage individual entries on the history list, or set
parameters managing the list itself.
.Fn1 void add_history "const char *string"
Place \fIstring\fP at the end of the history list. The associated data
field (if any) is set to \fBNULL\fP.
.Fn1 void add_history_time "const char *string"
Change the time stamp associated with the most recent history entry to
\fIstring\fP.
.Fn1 "HIST_ENTRY *" remove_history "int which"

and containing structure.
.Fn1 "histdata_t" free_history_entry "HIST_ENTRY *histent"
Free the history entry \fIhistent\fP and any history library private
data associated with it. Returns the application-specific data
so the caller can dispose of it.
.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.
This returns the old entry so the caller can dispose of any
application-specific data. In the case
of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
.Fn1 void clear_history "void"
Clear the history list by deleting all the entries.
.Fn1 void stifle_history "int max"
Stifle the history list, remembering only the last \fImax\fP entries.
.Fn1 int unstifle_history "void"
Stop stifling the history. This returns the previously-set
maximum number of history entries (as set by \fBstifle_history()\fP).
history was stifled. The value is positive if the history was
stifled, negative if it wasn't.
.Fn1 int history_is_stifled "void"
Returns non-zero if the history is stifled, zero if it is not.
.SS Information About the History List
These functions return information about the entire history list or
individual list entries.
.Fn1 "HIST_ENTRY **" history_list "void"
Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
current input history. Element 0 of this list is the beginning of time.
If there is no history, return \fBNULL\fP.
.Fn1 int where_history "void"
Returns the offset of the current history element.
.Fn1 "HIST_ENTRY *" current_history "void"
Return the history entry at the current position, as determined by
\fBwhere_history()\fP. If there is no entry there, return a \fBNULL\fP
pointer.
.Fn1 "HIST_ENTRY *" history_get "int offset"
Return the history entry at position \fIoffset\fP, starting from
\fBhistory_base\fP.

is greater than the history length, return a \fBNULL\fP pointer.
.Fn1 "time_t" history_get_time "HIST_ENTRY *"
Return the time stamp associated with the history entry passed as the argument.
.Fn1 int history_total_bytes "void"
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.
.SS Moving Around the History List
These functions allow the current index into the history list to be
set or changed.
.Fn1 int history_set_pos "int pos"
Set the current history offset to \fIpos\fP, an absolute index
into the list.
Returns 1 on success, 0 if \fIpos\fP is less than zero or greater
than the number of history entries.
.Fn1 "HIST_ENTRY *" previous_history "void"
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 \fBNULL\fP pointer.
.Fn1 "HIST_ENTRY *" next_history "void"
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 \fBNULL\fP pointer.
.SS Searching the History List
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 \fIanchored\fP,
meaning that the string must match at the beginning of the history entry.
.Fn2 int history_search "const char *string" "int direction"
Search the history for \fIstring\fP, starting at the current history offset.
If \fIdirection\fP is less than 0, then the search is through
previous entries, otherwise through subsequent entries.
If \fIstring\fP 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
\fIstring\fP was found. Otherwise, nothing is changed, and a -1 is
returned.
.Fn2 int history_search_prefix "const char *string" "int direction"
Search the history for \fIstring\fP, starting at the current history
offset. The search is anchored: matching lines must begin with
\fIstring\fP. If \fIdirection\fP is less than 0, then the search is
through previous entries, otherwise through subsequent entries.
If \fIstring\fP 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.
.Fn3 int history_search_pos "const char *string" "int direction" "int pos"
Search for \fIstring\fP in the history list, starting at \fIpos\fP, an
absolute index into the list. If \fIdirection\fP is negative, the search
proceeds backward from \fIpos\fP, otherwise forward. Returns the absolute
index of the history element where \fIstring\fP was found, or -1 otherwise.
.SS 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.
.Fn1 int read_history "const char *filename"
Add the contents of \fIfilename\fP to the history list, a line at a time.
If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP.
Returns 0 if successful, or \fBerrno\fP if not.
.Fn3 int read_history_range "const char *filename" "int from" "int to"
Read a range of lines from \fIfilename\fP, adding them to the history list.
Start reading at line \fIfrom\fP and end at \fIto\fP.
If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than
\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is
\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful,
or \fBerrno\fP if not.
.Fn1 int write_history "const char *filename"
Write the current history to \fIfilename\fP, overwriting \fIfilename\fP
if necessary.
If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP.
Returns 0 on success, or \fBerrno\fP on a read or write error.
.Fn2 int append_history "int nelements" "const char *filename"
Append the last \fInelements\fP of the history list to \fIfilename\fP.
If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP.
Returns 0 on success, or \fBerrno\fP on a read or write error.
.Fn2 int history_truncate_file "const char *filename" "int nlines"
Truncate the history file \fIfilename\fP, leaving only the last
\fInlines\fP lines.
If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated.
Returns 0 on success, or \fBerrno\fP on failure.
.SS History Expansion
These functions implement history expansion.
.Fn2 int history_expand "char *string" "char **output"
Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer
to a string. Returns:
.RS
.PD 0
.TP
0
If no expansions took place (or, if the only change in
the text was the removal of escape characters preceding the history expansion
character);
.TP
1
if expansions did take place;
.TP
-1
if there was an error in expansion;
.TP
2
if the returned line should be displayed, but not executed,
as with the \fB:p\fP modifier.
.PD
.RE
If an error ocurred in expansion, then \fIoutput\fP contains a descriptive
error message.
.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar"
Returns the text of the history event beginning at \fIstring\fP +
\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event
specifier. At function entry, \fIcindex\fP points to the index into
\fIstring\fP where the history event specification begins. \fIqchar\fP
is a character that is allowed to end the event specification in addition
to the ``normal'' terminating characters.
.Fn1 "char **" history_tokenize "const char *string"
Return an array of tokens parsed out of \fIstring\fP, much as the
shell might.
The tokens are split on the characters in the
\fBhistory_word_delimiters\fP variable,
and shell quoting conventions are obeyed.
.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string"
Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP
arguments present in \fIstring\fP. Arguments are split using
\fBhistory_tokenize()\fP.
.SS History Variables
This section describes the externally-visible variables exported by
the GNU History Library.
.Vb int history_base
The logical offset of the first entry in the history list.
.Vb int history_length
The number of entries currently stored in the history list.
.Vb int history_max_entries
The maximum number of history entries. This must be changed using
\fBstifle_history()\fP.
.Vb int history_write_timestamps
If non-zero, timestamps are written to the history file, so they can be
preserved between sessions. The default value is 0, meaning that
timestamps are not saved.
.Vb char history_expansion_char
The character that introduces a history event. The default is \fB!\fP.
Setting this to 0 inhibits history expansion.
.Vb char history_subst_char
The character that invokes word substitution if found at the start of
a line. The default is \fB^\fP.
.Vb 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.
.Vb "char *" history_word_delimiters
The characters that separate tokens for \fBhistory_tokenize()\fP.
The default value is \fB"\ \et\en()<>;&|"\fP.
.Vb "char *" history_no_expand_chars
The list of characters which inhibit history expansion if found immediately
following \fBhistory_expansion_char\fP. The default is space, tab, newline,
\fB\er\fP, and \fB=\fP.
.Vb "char *" history_search_delimiter_chars
The list of additional characters which can delimit a history search
string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
a substring search. The default is empty.
.Vb int history_quotes_inhibit_expansion
If non-zero, single-quoted words are not scanned for the history expansion
character. The default value is 0.
.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
This should be set to the address of a function that takes two arguments:
a \fBchar *\fP (\fIstring\fP)
and an \fBint\fP index into that string (\fIi\fP).
It should return a non-zero value if the history expansion starting at
\fIstring[i]\fP should not be performed; zero if the expansion should
be done.
It is intended for use by applications like \fBbash\fP that use the history
expansion character for additional purposes.
By default, this variable is set to \fBNULL\fP.

@node Introduction to History
@section Introduction to History
Many programs read input from the user a line at a time. The @sc{gnu}
History library is able to keep track of those lines, associate arbitrary
data with each line, and utilize information from previous lines in
composing new ones.
The programmer using the History library has available functions
for remembering lines on a history list, associating arbitrary data
with a line, removing lines from the list, searching through the list
for a line containing an arbitrary text string, and referencing any line
in the list directly. In addition, a history @dfn{expansion} function
is available which provides for a consistent user interface across
different programs.
The user using programs written with the History library has the
benefit of a consistent user interface with a set of well-known
commands for manipulating the text of previous lines and using that text
in new commands. The basic history manipulation commands are similar to
the history substitution provided by @code{csh}.
If the programmer desires, he can use the Readline library, which
includes some history manipulation by default, and has the added
advantage of command line editing.
Before declaring any functions using any functionality the History
library provides in other code, an application writer should include
the file @code{<readline/history.h>} in any file that uses the
History library's features. It supplies extern declarations for all
of the library's public functions and variables, and declares all of
the public data structures.
@node History Storage
@section History Storage
The history list is an array of history entries. A history entry is

@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 current history offset to @var{pos}, an absolute index
into the list.
Returns 1 on success, 0 if @var{pos} is less than zero or greater
than the number of history entries.
@end deftypefun
@deftypefun {HIST_ENTRY *} previous_history (void)
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 (void)
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 (const char *string, int direction)
Search the history for @var{string}, starting at the current history offset.
If @var{direction} is less than 0, then the search is through
previous entries, otherwise through subsequent entries.
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 (const 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} is less than 0, then the search is
through previous entries, otherwise through subsequent entries.
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 (const 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 (const 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 @code{errno} if not.
@end deftypefun
@deftypefun int read_history_range (const 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 (const 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}.
Returns 0 on success, or @code{errno} on a read or write error.
@end deftypefun
@deftypefun int append_history (int nelements, const char *filename)
Append the last @var{nelements} of the history list to @var{filename}.
If @var{filename} is @code{NULL}, then append to @file{~/.history}.
Returns 0 on success, or @code{errno} on a read or write error.
@end deftypefun
@deftypefun int history_truncate_file (const char *filename, int nlines)
Truncate the history file @var{filename}, leaving only the last
@var{nlines} lines.
If @var{filename} is @code{NULL}, then @file{~/.history} is truncated.
Returns 0 on success, or @code{errno} on failure.
@end deftypefun
@node History Expansion
@subsection History Expansion
These functions implement 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 removal of escape characters preceding 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 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 *} get_history_event (const 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 (const char *string)
Return an array of tokens parsed out of @var{string}, much as the
shell might. The tokens are split on the characters in the
@var{history_word_delimiters} variable,
and shell quoting conventions are obeyed.
@end deftypefun
@deftypefun {char *} history_arg_extract (int first, int last, const char *string)
Extract a string segment consisting of the @var{first} through @var{last}
arguments present in @var{string}. Arguments are split using
@code{history_tokenize}.
@end deftypefun
@node History Variables
@section History Variables
This section describes the externally-visible variables exported by
the @sc{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 history_max_entries
The maximum number of history entries. This must be changed using
@code{stifle_history()}.
@end deftypevar
@deftypevar int history_write_timestamps
If non-zero, timestamps are written to the history file, so they can be
preserved between sessions. The default value is 0, meaning that
timestamps are not saved.
@end deftypevar
@deftypevar char history_expansion_char
The character that introduces a history event. The default is @samp{!}.
Setting this to 0 inhibits history expansion.
@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_word_delimiters
The characters that separate tokens for @code{history_tokenize()}.
The default value is @code{" \t\n()<>;&|"}.
@end deftypevar
@deftypevar {char *} history_search_delimiter_chars
The list of additional characters which can delimit a history search
string, in addition to space, TAB, @samp{:} and @samp{?} in the case of
a substring search. The default is empty.
@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 space, tab, newline,
carriage return, and @samp{=}.
@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 {rl_linebuf_func_t *} 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 @code{int} 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 @code{NULL}.
@end deftypevar

@cindex command history
@cindex history list
When the @option{-o history} option to the @code{set} builtin
is enabled (@pxref{The Set Builtin}),
the shell provides access to the @dfn{command history},
the list of commands previously typed.
The value of the @env{HISTSIZE} shell variable is used as the
number of commands to save in a history list.
The text of the last @env{$HISTSIZE}
commands (default 500) is saved.
The shell stores each command in the history list prior to
parameter and variable expansion
but after history expansion is performed, subject to the
values of the shell variables
@env{HISTIGNORE} and @env{HISTCONTROL}.
When the shell starts up, the history is initialized from the
file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
The file named by the value of @env{HISTFILE} is truncated, if
necessary, to contain no more than the number of lines specified by
the value of the @env{HISTFILESIZE} variable.
When an interactive shell exits, the last
@env{$HISTSIZE} lines are copied from the history list to the file
named by @env{$HISTFILE}.
If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
the lines are appended to the history file,
otherwise the history file is overwritten.
If @env{HISTFILE}
is unset, or if the history file is unwritable, the history is
not saved. After saving the history, the history file is truncated
to contain no more than @env{$HISTFILESIZE}
lines. If @env{HISTFILESIZE} is not set, no truncation is performed.
If the @env{HISTTIMEFORMAT} is set, the time stamp information
associated with each history entry is written to the history file.
The builtin command @code{fc} may be used to list or edit and re-execute
a portion of the history list.
The @code{history} builtin may be used to display or modify the history
list and manipulate the history file.
When using command-line editing, search commands
are available in each editing mode that provide access to the
history list (@pxref{Commands For History}).
The shell allows control over which commands are saved on the history
list. The @env{HISTCONTROL} and @env{HISTIGNORE}
variables may be set to cause the shell to save only a subset of the
commands entered.
The @code{cmdhist}
shell option, if enabled, causes the shell to attempt to save each
line of a multi-line command in the same history entry, adding
semicolons where necessary to preserve syntactic correctness.
The @code{lithist}
shell option causes the shell to save the command with embedded newlines
instead of semicolons.
The @code{shopt} builtin is used to set these options.
@xref{Bash Builtins}, for a description of @code{shopt}.
@node Bash History Builtins
@section Bash History Builtins
@cindex history builtins
Bash provides two builtin commands which manipulate the
history list and history file.
@table @code
@item fc
@btindex fc
@example
@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]}
@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
@end example
Fix Command. In the first form, a range of commands from @var{first} to
@var{last} is selected from the history list. Both @var{first} and
@var{last} may be specified as a string (to locate the most recent
command beginning with that string) or as a number (an index into the
history list, where a negative number is used as an offset from the
current command number). If @var{last} is not specified it is set to
@var{first}. If @var{first} is not specified it is set to the previous
command for editing and @minus{}16 for listing. If the @option{-l} flag is
given, the commands are listed on standard output. The @option{-n} flag
suppresses the command numbers when listing. The @option{-r} flag
reverses the order of the listing. Otherwise, the editor given by
@var{ename} is invoked on a file containing those commands. If
@var{ename} is not given, the value of the following variable expansion
is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}. This says to use the
value of the @env{FCEDIT} variable if set, or the value of the
@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
When editing is complete, the edited commands are echoed and executed.
In the second form, @var{command} is re-executed after each instance
of @var{pat} in the selected command is replaced by @var{rep}.
A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
that typing @samp{r cc} runs the last command beginning with @code{cc}
and typing @samp{r} re-executes the last command (@pxref{Aliases}).
@item history
@btindex history
@example
history [@var{n}]
history -c
history -d @var{offset}
history [-anrw] [@var{filename}]
history -ps @var{arg}
@end example
With no options, display the history list with line numbers.
Lines prefixed with a @samp{*} have been modified.
An argument of @var{n} lists only the last @var{n} lines.
If the shell variable @env{HISTTIMEFORMAT} is set and not null,
it is used as a format string for @var{strftime} to display
the time stamp associated with each displayed history entry.
No intervening blank is printed between the formatted time stamp
and the history line.
Options, if supplied, have the following meanings:
@table @code
@item -c
Clear the history list. This may be combined
with the other options to replace the history list completely.
@item -d @var{offset}
Delete the history entry at position @var{offset}.
@var{offset} should be specified as it appears when the history is
displayed.
@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 -r
Read the current history file and append its contents to
the history list.
@item -w
Write out the current history to the history file.
@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.
@item -s
The @var{arg}s are added to the end of
the history list as a single entry.
@end table
When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
used, if @var{filename}
is given, then it is used as the history file. If not, then
the value of the @env{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 @option{-p} option to the @code{history} builtin command
may be used to see what a history expansion will do before using it.
The @option{-s} option to the @code{history} builtin may be used to
add commands to the end of the history list without actually executing
them, so that they are available for subsequent recall.
This is most useful in conjunction with Readline.
The shell allows control of the various characters used by the
history expansion mechanism with the @code{histchars} variable.

@end menu
@node Event Designators
@subsection Event Designators
@cindex event designators
An event designator is a reference to a command line entry in the
history list.
@cindex history events
@table @asis
@item @code{!}
@ifset BashFeatures
Start a history substitution, except when followed by a space, tab,
the end of the line, @samp{=} or @samp{(} (when the
@code{extglob} shell option is enabled using the @code{shopt} builtin).
@end ifset
@ifclear BashFeatures
Start a history substitution, except when followed by a space, tab,
the end of the line, or @samp{=}.
@end ifclear
@item @code{!@var{n}}
Refer to command line @var{n}.
@item @code{!-@var{n}}
Refer to the command @var{n} lines back.
@item @code{!!}
Refer to the previous command. 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{$},
@samp{*}, @samp{-}, or @samp{%}. Words are numbered from the beginning
of the line, with the first word being denoted by 0 (zero). Words are
inserted into the current line separated by single spaces.
@need 0.75
For example,
@table @code
@item !!
designates the preceding command. When you type this, the preceding
command is repeated in toto.
@item !!:$
designates the last argument of the preceding command. This may be
shortened to @code{!$}.
@item !fi:2
designates the second argument of the most recent command starting with
the letters @code{fi}.
@end table
@need 0.75
Here are the word designators:
@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
@itemx a
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{&}.
@item G
Apply the following @samp{s} modifier once to each word in the event.

/*
From: Jeff Solomon <jsolomon@stanford.edu>
Date: Fri, 9 Apr 1999 10:13:27 -0700 (PDT)
To: chet@po.cwru.edu
Subject: new readline example
Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
Chet,
I've been using readline 4.0. Specifically, I've been using the perl
version Term::ReadLine::Gnu. It works great.
Anyway, I've been playing around the alternate interface and I wanted
to contribute a little C program, callback.c, to you that you could
use as an example of the alternate interface in the /examples
directory of the readline distribution.
My example shows how, using the alternate interface, you can
interactively change the prompt (which is very nice imo). Also, I
point out that you must roll your own terminal setting when using the
alternate interface because readline depreps (using your parlance) the
terminal while in the user callback. I try to demostrate what I mean
with an example. I've included the program below.
To compile, I just put the program in the examples directory and made
the appropriate changes to the EXECUTABLES and OBJECTS line and added
an additional target 'callback'.
I compiled on my Sun Solaris2.6 box using Sun's cc.
Let me know what you think.
Jeff

/* This little examples demonstrates the alternate interface to using readline.
* In the alternate interface, the user maintains control over program flow and
* only calls readline when STDIN is readable. Using the alternate interface,
* you can do anything else while still using readline (like talking to a
* network or another program) without blocking.
*
* Specifically, this program highlights two importants features of the
* alternate interface. The first is the ability to interactively change the
* prompt, which can't be done using the regular interface since rl_prompt is
* read-only.
*
* The second feature really highlights a subtle point when using the alternate
* interface. That is, readline will not alter the terminal when inside your
* callback handler. So let's so, your callback executes a user command that
* takes a non-trivial amount of time to complete (seconds). While your
* executing the command, the user continues to type keystrokes and expects them
* to be re-echoed on the new prompt when it returns. Unfortunately, the default
* terminal configuration doesn't do this. After the prompt returns, the user
* must hit one additional keystroke and then will see all of his previous
* keystrokes. To illustrate this, compile and run this program. Type "sleep" at
* the prompt and then type "bar" before the prompt returns (you have 3
* seconds). Notice how "bar" is re-echoed on the prompt after the prompt
* returns? This is what you expect to happen. Now comment out the 4 lines below
* the line that says COMMENT LINE BELOW. Recompile and rerun the program and do
* the same thing. When the prompt returns, you should not see "bar". Now type
* "f", see how "barf" magically appears? This behavior is un-expected and not
* desired.

Subject: fgets(stdin) --> readline() redirector
To: chet@po.cwru.edu
Hi Chet,
Here is something you may find useful enough to include in the readline
distribution. It is a shared library that redirects calls to fgets(stdin)
to readline() via LD_PRELOAD, and it supports a custom prompt and list of
command names. Many people have asked me for this file, so I thought I'd
pass it your way in hope of just including it with readline to begin with.
Best Regards,
-Harold

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

2004-11-04 Per Bothner <per@bothner.com>
* pty.c: Import from screen-4.0.2.
* configure.in, Makefile.in, config.h.in: Set up autoconf handling,
copying a bunk of stuff over from screen.
* rlfe.c: Use OpenPTY from pty.c instead of get_master_pty.
2004-11-03 Per Bothner <per@bothner.com>
* rlfe.c: Get input emphasis (boldening) more robust.
* rlfe.c: Various cleanups on comments and names.
2003-11-07 Wolfgang Taeuber <wolfgang_taeuber@agilent.com>
* Specify a history file and the size of the history file with command
* line options; use EDITOR/VISUAL to set vi/emacs preference.
1999-09-03 Chet Ramey <chet@nike.ins.cwru.edu>
* fep.c: Memmove is not universally available. This patch assumes
that an autoconf test has been performed, and that memcpy is
available without checking.
* fep.c: VDISCARD is not universally available, even when termios is.
* fep.c: If a system doesn't have TIOCSCTTY, the first `open'
performed after setsid allocates a controlling terminal. The
original code would leave the child process running on the slave pty
without a controlling tty if TIOCSCTTY was not available.
* fep.c: Most versions of SVR4, including solaris, don't allow
terminal ioctl calls on the master side of the pty.
1999-08-28 Per Bothner <per@bothner.com>
* fep.c: Initial release.

rlfe (ReadLine Front-End) is a "universal wrapper" around readline.
You specify an interactive program to run (typically a shell), and
readline is used to edit input lines.
There are other such front-ends; what distinguishes this one is that
it monitors the state of the inferior pty, and if the inferior program
switches its terminal to raw mode, then rlfe passes your characters
through directly. This basically means you can run your entire
session (including bash and terminal-mode emacs) under rlfe.
FEATURES
* Can use all readline commands (and history) in commands that
read input lines in "canonical mode" - even 'cat'!
* Automatically switches between "readline-editing mode" and "raw mode"
depending on the terminal mode. If the inferior program invokes
readline itself, it will do its own line editing. (The inferior
readline will not know about rlfe, and it will have its own history.)
You can even run programs like 'emavs -nw' and 'vi' under rlfe.
The goal is you could leave rlfe always on without even knowing
about it. (We're not quite there, but it works tolerably well.)
* The input line (after any prompt) is changed to bold-face.
INSTALL
The usual: ./configure && make && make install
Note so far rlfe has only been tested on GNU Linux (Fedora Core 2)
and Mac OS X (10.3).
This assumes readline header files and libraries are in the default
places. If not, you can create a link named readline pointing to the
readline sources. To link with libreadline.a and libhistory.a
you can copy or link them, or add LDFLAGS='-/path/to/readline' to
the make command-line.
USAGE
Just run it. That by default runs bash. You can run some other
command by giving it as command-line arguments.
There are a few tweaks: -h allows you to name the history file,
and -s allows you to specify its size. It default to "emacs" mode,
but if the the environment variable EDITOR is set to "vi" that
mode is chosen.
ISSUES
* The mode switching depends on the terminal mode set by the inferior
program. Thus ssh/telnet/screen-type programs will typically be in
raw mode, so rlfe won't be much use, even if remote programs run in
canonical mode. The work-around is to run rlfe on the remote end.
* Echo supression and prompt recognition are somewhat fragile.
(A protocol so that the o/s tty code can reliably communicate its
state to rlfe could solve this problem, and the previous one.)
* See the intro to rlfe.c for more notes.
* Assumes a VT100-compatible terminal, though that could be generalized
if anybody cares.
* Requires ncurses.
* It would be useful to integrate rlfe's logic in a terminal emulator.
That would make it easier to reposition the edit position with a mouse,
integrate cut-and-paste with the system clipboard, and more robustly
handle escape sequence and multi-byte characters more robustly.

/* PROBLEMS/TODO:
*
* Only tested under GNU/Linux and Mac OS 10.x; needs to be ported.
*
* Switching between line-editing-mode vs raw-char-mode depending on
* what tcgetattr returns is inherently not robust, plus it doesn't
* work when ssh/telnetting in. A better solution is possible if the
* tty system can send in-line escape sequences indicating the current
* mode, echo'd input, etc. That would also allow a user preference
* to set different colors for prompt, input, stdout, and stderr.
*
* When running mc -c under the Linux console, mc does not recognize
* mouse clicks, which mc does when not running under rlfe.
*
* Pasting selected text containing tabs is like hitting the tab character,
* which invokes readline completion. We don't want this. I don't know
* if this is fixable without integrating rlfe into a terminal emulator.
*
* Echo suppression is a kludge, but can only be avoided with better kernel
* support: We need a tty mode to disable "real" echoing, while still
* letting the inferior think its tty driver to doing echoing.
* Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
*
* The latest readline may have some hooks we can use to avoid having
* to back up the prompt. (See HAVE_ALREADY_PROMPTED.)
*
* Desirable readline feature: When in cooked no-echo mode (e.g. password),
* echo characters are they are types with '*', but remove them when done.
*
* Asynchronous output while we're editing an input line should be
* inserted in the output view *before* the input line, so that the
* lines being edited (with the prompt) float at the end of the input.
*
* A "page mode" option to emulate more/less behavior: At each page of
* output, pause for a user command. This required parsing the output
* to keep track of line lengths. It also requires remembering the
* output, if we want an option to scroll back, which suggests that
* this should be integrated with a terminal emulator like xterm.
