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.

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.>

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

(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:

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

Basic Installation
==================
These are installation instructions for Readline-5.1.
These are generic installation instructions.
The simplest way to compile readline is:
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
1. `cd' to the directory containing the readline source code and type
`./configure' to configure readline for your system. If you're
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes some time. While running, it prints some
Running `configure' takes awhile. 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.
2. Type `make' to compile the package.
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.
3. Optionally, type `make check' to run any self-tests that come with
the package.
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
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the 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.
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
Or on systems that have the `env' program, you can do it like this:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile readline for more than one kind of computer at the
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
@ -83,205 +90,140 @@ 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.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a

package 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'.
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.
If you give `configure' the option `--exec-prefix=PATH', the
readline Makefiles will use PATH as the prefix for installing the
libraries. Documentation and other data files will still use the
regular prefix.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' 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).
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
See the file `config.sub' for the possible values of each field.
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the `--target=TYPE' option to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
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.
A warning: not all `configure' scripts look for a site script.
Operation Controls
Defining Variables
==================
`configure' recognizes the following options to control how it
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script).
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--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'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made.
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.
`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-5.1 since
the release of readline-5.0.
1. 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. New application-callable auxiliary function, rl_variable_value, returns
a string corresponding to a readline variable's value.
g. When parsing inputrc files and variable binding commands, the parser
strips trailing whitespace from values assigned to boolean variables
before checking them.
h. 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.

Introduction
============
This is the Gnu Readline library, version 5.1.
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.

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.

## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do

* key.c: This module contains the procedures for maintaining

*
* An extended-key (key) is a sequence of keystrokes introduced
* with a sequence introducer and consisting of an arbitrary
* number of characters. This module maintains a map (the el->el_key.map)
* to convert these extended-key sequences into input strs
* (XK_STR), editor functions (XK_CMD), or unix commands (XK_EXE).
*
* Warning:
* If key is a substr of some other keys, then the longer
* keys are lost!! That is, if the keys "abcd" and "abcef"
* are in el->el_key.map, adding the key "abc" will cause the first two
* definitions to be lost.
*
* Restrictions:
* -------------
* 1) It is not possible to have one key that is a
* substr of another.
