readline-8.3/CHANGES 000644 000436 000024 00000254116 15013112710 014223 0 ustar 00chet staff 000000 000000 This document details the changes between this version, readline-8.3, and
the previous version, readline-8.2.
1. Changes to Readline
a. Fixed a bug in clearing the visible line structure before redisplay.
b. Fix a bug where setlocale(3) returning NULL caused a crash.
c. Fixed signal checking in callback mode to handle signals that arrive before
readline restore's the application's signal handlers.
d. Fixed a bug with word completion where the directory name needs to be
dequoted and tilde-expanded.
e. Fixed a bug that caused compilation to fail on systems with select but not
pselect.
f. System-specific changes for: WIN32, z/OS, Cygwin, MSYS
g. Fixed a bug that caused word completion mismatches if the quoted text the
user typed was longer than the unquoted match.
h. Fixes for freeing undo lists that might appear in history list entries
after non-incremental searches.
i. Fixes for some errors revealed by address sanitizer.
j. In vi mode, if an `f' or `F' move command associated with a `c' or `C'
command fails, don't enter insert mode.
k. Fixed bug with truncating a history file containing timestamps that caused
the timestamp associated with the first history entry not to be written.
l. Fix vi-mode so that a motion command attached to d/D, y/Y, or t/T must
consume or delete at least one character.
m. Fix a redisplay error when displaying meta characters as octal sequences
and other C locale issues.
n. Fix error that caused characters composing an incomplete multibyte
character not to be inserted into the line.
o. In callback mode, let the application echo the signal characters (e.g., ^C)
when the application's signal handlers are installed.
p. Added some support for lines that consume more than the physical number of
screen lines.
q. Make sure dump-variables returns the string values for active-region-start-color
and active-region-end-color if they're set.
r. Fixes to how characters between 128 and 159 are printed when displaying
macro values (use symbolic notation instead of directly printing the
character).
s. Don't convert meta characters that contain NULL (\M-\C-@) to actual NULs,
which prematurely terminates the macro value.
t. Fix typo in the readline color prefix extension that it uses for coloring
filename prefixes when displaying possible completions.
u. Call the filename rewrite hook on the word being completed before comparing
it against possible completions from the file system to get consistent
strings.
v. Fix infinite recursion that can happen if someone binds a key that doesn't
have a different upper and lower case represenation to do-lowercase-version.
w. Check for non-ANSI (dumb) terminals a little more thoroughly.
x. Don't attempt to history-expand the `quick substitution' character at the
beginning of a line if the application has set the quoting state to single
quotes.
y. Fix small memory leak if non-incremental or incremental search is
interrupted by a signal.
z. Loading very large history files should be much faster.
aa. Retry opening startup files if the open is interrupted by a signal
and is not automatically restarted.
bb. Make sure the bracketed-paste input buffer is null-terminated when read
returns an error.
cc. Fixed a small memory leak in execute-named-command if the command doesn't
exist or the function doesn't return.
dd. Fix for attempting to change case of invalid multibyte characters.
ee. Fix for possible completions that compare identically when using case-
insensitive completion but have different byte lengths.
ff. Fix to make non-incremental searches use undo lists and set the history
position the same way as incremental searches.
gg. Don't check for signals when handling a received signal.
hh. Fix off-by-one error when tokenizing words like $((expr)) while performing
history expansion.
ii. Fixes for incremental searches and redisplay in the C locale.
jj. Fixes for some use-after-free of the undo list errors when stacking multiple
commands that use rl_maybe_replace_line to save changes to a history entry.
kk. Fixes to ensure that completion-prefix-display-length and
colored-completion-prefix are mutually exclusive.
ll. Fixed a bug that allowed a history search to change the current history
list position.
mm. Fixed a bug that allowed ^G to retain a saved command to execute.
nn. Updates to new export-completions command to allow filename suffixes.
oo. Fixed a redisplay bug with prompts containing multiple sequences of
invisible characters that are longer than the screen width.
pp. The history library no longer skips blank lines while it is reading a
multiline history entry from a history file.
2. New Features in Readline
a. Output a newline if there is no prompt and readline reads an empty line.
b. The history library falls back to stdio when writing the history list if
mmap fails.
c. New bindable variable `search-ignore-case', causes readline to perform
case-insensitive incremental and non-incremental history searches.
d. rl_full_quoting_desired: new application-settable variable, causes all
completions to be quoted as if they were filenames.
e. rl_macro_display_hook: new application-settable function pointer, used if
the application wants to print macro values itself instead of letting
readline do it
f. rl_reparse_colors: new application-callable function, reparses $LS_COLORS
(presumably after the user changes it)
g. rl_completion_rewrite_hook: new application-settable function pointer,
called to modify the word being completed before comparing it against
pathnames from the file system.
h. execute-named-command: a new bindable command that reads the name of a
readline command from the standard input and executes it. Bound to M-x
in emacs mode by default.
i. Incremental and non-incremental searches now allow ^V/^Q (or, in the former
case, anything bound to quoted-insert) to quote characters in the search
string.
j. Documentation has been significantly updated.
k. New `force-meta-prefix' bindable variable, which forces the use of ESC as
the meta prefix when using "\M-" in key bindings instead of overloading
convert-meta.
l. The default value for `readline-colored-completion-prefix' no longer has a
leading `.'; the original report was based on a misunderstanding.
m. There is a new bindable command, `export-completions', which writes the
possible completions for a word to the standard output in a defined format.
n. Readline can reset its idea of the screen dimensions when executing after
a SIGCONT.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-8.2, and
the previous version, readline-8.1.
1. Changes to Readline
a. Fixed a problem with cleaning up active marks when using callback mode.
b. Fixed a problem with arithmetic comparison operators checking the version.
c. Fixed a problem that could cause readline not to build on systems without
POSIX signal functions.
d. Fixed a bug that could cause readline to crash if the application removed
the callback line handler before readline read all typeahead.
e. Added additional checks for read errors in the middle of readline commands.
f. Fixed a redisplay problem that occurred when switching from the digit-
argument prompt `(arg: N)' back to the regular prompt and the regular
prompt contained invisible characters.
g. Fixed a problem with restoring the prompt when aborting an incremental
search.
h. Fix a problem with characters > 128 not being displayed correctly in certain
single-byte encodings.
i. Fixed a problem with unix-filename-rubout that caused it to delete too much
when applied to a pathname consisting only of one or more slashes.
j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
the screen changed dimensions during a call to readline() and the prompt
became longer than the screen width.
k. Fixed a problem that caused the \r output by turning off bracketed paste
to overwrite the line if terminal echo was disabled.
l. Fixed a bug that could cause colored-completion-prefix to not display if
completion-prefix-display-length was set.
m. Fixed a problem with line wrapping prompts when a group of invisible
characters runs to the right edge of the screen and the prompt extends
longer then the screen width.
n. Fixed a couple problems that could cause rl_end to be set incorrectly by
transpose-words.
o. Prevent some display problems when running a command as the result of a
trap or one bound using `bind -x' and the command generates output.
p. Fixed an issue with multi-line prompt strings that have one or more
invisible characters at the end of a physical line.
q. Fixed an issue that caused a history line's undo list to be cleared when
it should not have been.
r. When replacing a history entry, make sure the existing entry has a non-NULL
timestamp before copying it; it may have been added by the application, not
the history library.
2. New Features in Readline
a. There is now an HS_HISTORY_VERSION containing the version number of the
history library for applications to use.
b. History expansion better understands multiple history expansions that may
contain strings that would ordinarily inhibit history expansion (e.g.,
`abc!$!$').
c. There is a new framework for readline timeouts, including new public
functions to set timeouts and query how much time is remaining before a
timeout hits, and a hook function that can trigger when readline times
out. There is a new state value to indicate a timeout.
d. Automatically bind termcap key sequences for page-up and page-down to
history-search-backward and history-search-forward, respectively.
e. There is a new `fetch-history' bindable command that retrieves the history
entry corresponding to its numeric argument. Negative arguments count back
from the end of the history.
f. `vi-undo' is now a bindable command.
g. There is a new option: `enable-active-region'. This separates control of
the active region and bracketed-paste. It has the same default value as
bracketed-paste, and enabling bracketed paste enables the active region.
Users can now turn off the active region while leaving bracketed paste
enabled.
h. rl_completer_word_break_characters is now `const char *' like
rl_basic_word_break_characters.
i. Readline looks in $LS_COLORS for a custom filename extension
(*.readline-colored-completion-prefix) and uses that as the default color
for the common prefix displayed when `colored-completion-prefix' is set.
j. Two new bindable string variables: active-region-start-color and
active-region-end-color. The first sets the color used to display the
active region; the second turns it off. If set, these are used in place
of terminal standout mode.
k. New readline state (RL_STATE_EOF) and application-visible variable
(rl_eof_found) to allow applications to detect when readline reads EOF
before calling the deprep-terminal hook.
l. There is a new configuration option: --with-shared-termcap-library, which
forces linking the shared readline library with the shared termcap (or
curses/ncurses/termlib) library so applications don't have to do it.
m. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
each time it is called, and modifies the appropriate locale-specific display
and key binding variables when the locale changes.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-8.1, and
the previous version, readline-8.0.
1. Changes to Readline
a. There are a number of fixes that were found as the result of fuzzing with
random input.
b. Changed the revert-all-at-newline behavior to make sure to start at the end
of the history list when doing it, instead of the line where the user hit
return.
c. When parsing `set' commands from the inputrc file or an application, readline
now allows trailing whitespace.
d. Fixed a bug that left a file descriptor open to the history file if the
file size was 0.
e. Fixed a problem with binding key sequences containing meta characters.
f. Fixed a bug that caused the wrong line to be displayed if the user tried to
move back beyond the beginning of the history list, or forward past the end
of the history list.
g. If readline catches SIGTSTP, it now sets a hook that allows the calling
application to handle it if it desires.
h. Fixed a redisplay problem with a prompt string containing embedded newlines.
i. Fixed a problem with completing filenames containing invalid multibyte
sequences when case-insensitive comparisons are enabled.
j. Fixed a redisplay problem with prompt strings containing invisible multibyte
characters.
k. Fixed a problem with multibyte characters mapped to editing commands that
modify the search string in incremental search.
l. Fixed a bug with maintaining the key sequence while resolving a bound
command in the presence of ambiguous sequences (sequences with a common
prefix), in most cases while attempting to unbind it.
m. Fixed several buffer overflows found as the result of fuzzing.
n. Reworked backslash handling when translating key sequences for key binding
to be more uniform and consistent, which introduces a slight backwards
incompatibility.
o. Fixed a bug with saving the history that resulted in errors not being
propagated to the calling application when the history file is not writable.
p. Readline only calls chown(2) on a newly-written history file if it really
needs to, instead of having it be a no-op.
q. Readline now behaves better when operate-and-get-next is used when the
history list is `full': when there are already $HISTSIZE entries.
r. Fixed a bug that could cause vi redo (`.') of a replace command not to work
correctly in the C or POSIX locale.
s. Fixed a bug with vi-mode digit arguments that caused the last command to be
set incorrectly. This prevents yank-last-arg from working as intended, for
example.
t. Make sure that all undo groups are closed when leaving vi insertion mode.
u. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
the motion command doesn't have any effect.
v. Fixed several potential memory leaks in the callback mode context handling.
w. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
executing the terminal cleanup code, since it's no longer run in a signal
handling context.
x. Fixed a bug that could cause an application with an application-specific
redisplay function to crash if the line data structures had not been
initialized.
y. Terminals that are named "dumb" or unknown do not enable bracketed paste
by default.
z. Ensure that disabling bracketed paste turns off highlighting the incremental
search string when the search is successful.
2. New Features in Readline
a. If a second consecutive completion attempt produces matches where the first
did not, treat it as a new completion attempt and insert a match as
appropriate.
b. Bracketed paste mode works in more places: incremental search strings, vi
overstrike mode, character search, and reading numeric arguments.
c. Readline automatically switches to horizontal scrolling if the terminal has
only one line.
d. Unbinding all key sequences bound to a particular readline function now
descends into keymaps for multi-key sequences.
e. rl-clear-display: new bindable command that clears the screen and, if
possible, the scrollback buffer (bound to emacs mode M-C-l by default).
f. New active mark and face feature: when enabled, it will highlight the text
inserted by a bracketed paste (the `active region') and the text found by
incremental and non-incremental history searches. This is tied to bracketed
paste and can be disabled by turning off bracketed paste.
g. Readline sets the mark in several additional commands.
h. Bracketed paste mode is enabled by default. There is a configure-time
option (--enable-bracketed-paste-default) to set the default to on or off.
i. Readline tries to take advantage of the more regular structure of UTF-8
characters to identify the beginning and end of characters when moving
through the line buffer.
j. The bindable operate-and-get-next command (and its default bindings) are
now part of readline instead of a bash-specific addition.
k. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-8.0, and the
previous version, readline-7.0.
1. Changes to Readline
a. Added a guard to prevent nested macros from causing an infinite expansion
loop.
b. Instead of allocating enough history list entries to hold the maximum list
size, cap the number allocated initially.
c. Added a strategy to avoid allocating huge amounts of memory if a block of
history entries without timestamps occurs after a block with timestamps.
d. Added support for keyboard timeouts when an ESC character is the last
character in a macro.
e. There are several performance improvements when in a UTF-8 locale.
f. Readline does a better job of preserving the original set of blocked
signals when using pselect() to wait for input.
g. Fixed a bug that caused multibyte characters in macros to be mishandled.
h. Fixed several bugs in the code that calculates line breaks when expanding
prompts that span several lines, contain multibyte characters, and contain
invisible character seqeuences.
i. Fixed several bugs in cursor positioning when displaying lines with prompts
containing invisible characters and multibyte characters.
j. When performing case-insensitive completion, Readline no longer sorts the
list of matches unless directed to do so.
k. Fixed a problem with key sequences ending with a backslash.
l. Fixed out-of-bounds and free memory read errors found via fuzzing.
m. Fixed several cases where the mark was set to an invalid value.
n. Fixed a problem with the case-changing operators in the case where the
lower and upper case versions of a character do not have the same number
of bytes.
o. Handle incremental and non-incremental search character reads returning EOF.
p. Handle the case where a failing readline command at the end of a multi-key
sequence could be misinterpreted.
q. The history library now prints a meaningful error message if the history
file isn't a regular file.
r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
a multibyte character.
s. The key binding code now attempts to remove a keymap if a key unbinding
leaves it empty.
t. Fixed a line-wrapping issue that caused problems for some terminal
emulators.
u. If there is a key bound to the tty's VDISCARD special character, readline
disables VDISCARD while it is active.
v. Fixed a problem with exiting bracketed paste mode on terminals that assume
the bracketed paste mode character sequence contains visible characters.
w. Fixed a bug that could cause a key binding command to refer to an
uninitialized variable.
x. Added more UTF-8-specific versions of multibyte functions, and optimized
existing functions if the current locale uses UTF-8 encoding.
y. Fixed a problem with bracketed-paste inserting more than one character and
interacting with other readline functions.
z. Fixed a bug that caused the history library to attempt to append a history
line to a non-existent history entry.
aa. If using bracketed paste mode, output a newline after the \r that is the
last character of the mode disable string to avoid overwriting output.
bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better
handle multibyte characters.
cc. Fixed a redisplay problem that caused an extra newline to be generated on
accept-line when the line length is exactly the screenwidth.
dd. Fixed a bug with adding multibyte characters to an incremental search
string.
ee. Fixed a bug with redoing text insertions in vi mode.
ff. Fixed a bug with pasting text into an incremental search string if bracketed
paste mode is enabled. ESC cannot be one of the incremental search
terminator characters for this to work.
gg. Fixed a bug with anchored search patterns when performing searches in vi
mode.
2. New Features in Readline
a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
Posix specifies (uses fnmatch(3) if available).
b. There are new `next-screen-line' and `previous-screen-line' bindable
commands, which move the cursor to the same column in the next, or previous,
physical line, respectively.
c. There are default key bindings for control-arrow-key key combinations.
d. A negative argument (-N) to `quoted-insert' means to insert the next N
characters using quoted-insert.
e. New public function: rl_check_signals(), which allows applications to
respond to signals that readline catches while waiting for input using
a custom read function.
f. There is new support for conditionally testing the readline version in an
inputrc file, with a full set of arithmetic comparison operators available.
g. There is a simple variable comparison facility available for use within an
inputrc file. Allowable operators are equality and inequality; string
variables may be compared to a value; boolean variables must be compared to
either `on' or `off'; variable names are separated from the operator by
whitespace.
h. The history expansion library now understands command and process
substitution and extended globbing and allows them to appear anywhere in a
word.
i. The history library has a new variable that allows applications to set the
initial quoting state, so quoting state can be inherited from a previous
line.
j. Readline now allows application-defined keymap names; there is a new public
function, rl_set_keymap_name(), to do that.
k. The "Insert" keypad key, if available, now puts readline into overwrite
mode.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-7.0, and the
previous version, readline-6.3.
1. Changes to Readline
a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
commands with modifiers was fixed.
b. Fixed a bug that caused callback mode to dump core when reading a
multiple-key sequence (e.g., arrow keys).
c. Fixed a bug that caused the redisplay code to erase some of the line when
using horizontal scrolling with incremental search.
d. Readline's input handler now performs signal processing if read(2) is
interrupted by SIGALRM or SIGVTALRM.
e. Fixed a problem with revert-all-at-newline freeing freed memory.
f. Clarified the documentation for the history_quotes_inhibit_expansion
variable to note that it inhibits scanning for the history comment
character and that it only affects double-quoted strings.
g. Fixed an off-by-one error in the prompt printed when performing searches.
h. Use pselect(2), if available, to wait for input before calling read(2), so
a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
i. Some memory leaks caused by signals interrupting filename completion have
been fixed.
j. Reading EOF twice on a non-empty line causes EOF to be returned, rather
than the partial line. This can cause partial lines to be executed on
SIGHUP, for example.
k. Fixed a bug concerning deleting multibyte characters from the search
string while performing an incremental search.
l. Fixed a bug with tilde expanding directory names in filename completion.
m. Fixed a bug that did not allow binding sequences beginning with a `\'.
n. Fixed a redisplay bug involving incorrect line wrapping when the prompt
contains a multibyte character in the last screen column.
o. Fixed a bug that caused history expansion to disregard characters that are
documented to delimit a history event specifier without requiring `:'.
p. Fixed a bug that could cause reading past the end of a string when reading
the value when binding the set of isearch terminators.
q. Fixed a bug that caused readline commands that depend on knowing which
key invoked them to misbehave when dispatching key sequences that are
prefixes of other key bindings.
r. Paren matching now works in vi insert mode.
s. Colored completion prefixes are now displayed using a different color, less
likely to collide with files.
t. Fixed a bug that caused vi-mode character search to misbehave when
running in callback mode.
u. Fixed a bug that caused output to be delayed when input is coming from a
macro in vi-mode.
v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
a multi-key key sequence via a macro.
w. Fixed a bug that caused problems with applications that supply their own
input function when performing completion.
x. When read returns -1/EIO when attempting to read a key, return an error
instead of line termination back to the caller.
y. Updated tty auditing feature based on patch from Red Hat.
z. Fixed a bug that could cause the history library to crash on overflows
introduced by malicious editing of timestamps in the history file.
aa. The history file writing functions only attempt to create and use a backup
history file if the history file exists and is a regular file.
bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface.
cc. Fixed several redisplay bugs with prompt strings containing multibyte
and non-visible characters whose physical length is longer than the screen
width.
dd. Fixed a redisplay bug with prompt strings containing invisible characters
whose physical length exceeds the screen width and using incremental search.
ee. Readline prints more descriptive error messages when it encounters errors
while reading an inputrc file.
ff. Fixed a bug in the character insertion code that attempts to optimize
typeahead when it reads a character that is not bound to self-insert and
resets the key sequence state.
gg. When refreshing the line as the result of a key sequence, Readline attempts
to redraw only the last line of a multiline prompt.
hh. Fixed an issue that caused completion of git commands to display
incorrectly when using colored-completion-prefix.
ii. Fixed several redisplay bugs having to do with multibyte characters and
invisible characters in prompt strings.
jj. Fixed a bug that caused mode strings to be displayed incorrectly if the
prompt was shorter than the mode string.
2. New Features in Readline
a. The history truncation code now uses the same error recovery mechanism as
the history writing code, and restores the old version of the history file
on error. The error recovery mechanism handles symlinked history files.
b. There is a new bindable variable, `enable-bracketed-paste', which enables
support for a terminal's bracketed paste mode.
c. The editing mode indicators can now be strings and are user-settable
(new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
variables). Mode strings can contain invisible character sequences.
Setting mode strings to null strings restores the defaults.
d. Prompt expansion adds the mode string to the last line of a multi-line
prompt (one with embedded newlines).
e. There is a new bindable variable, `colored-completion-prefix', which, if
set, causes the common prefix of a set of possible completions to be
displayed in color.
f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
mode yank-pop.
g. The redisplay code underwent several efficiency improvements for multibyte
locales.
h. The insert-char function attempts to batch-insert all pending typeahead
that maps to self-insert, as long as it is coming from the terminal.
i. rl_callback_sigcleanup: a new application function that can clean up and
unset any state set by readline's callback mode. Intended to be used
after a signal.
j. If an incremental search string has its last character removed with DEL, the
resulting empty search string no longer matches the previous line.
k. If readline reads a history file that begins with `#' (or the value of
the history comment character) and has enabled history timestamps, the history
entries are assumed to be delimited by timestamps. This allows multi-line
history entries.
l. Readline now throws an error if it parses a key binding without a terminating
`:' or whitespace.
m. The default binding for ^W in vi mode now uses word boundaries specified
by Posix (vi-unix-word-rubout is bindable command name).
n. rl_clear_visible_line: new application-callable function; clears all
screen lines occupied by the current visible readline line.
o. rl_tty_set_echoing: application-callable function that controls whether
or not readline thinks it is echoing terminal output.
p. Handle >| and strings of digits preceding and following redirection
specifications as single tokens when tokenizing the line for history
expansion.
q. Fixed a bug with displaying completions when the prefix display length
is greater than the length of the completions to be displayed.
r. The :p history modifier now applies to the entire line, so any expansion
specifying :p causes the line to be printed instead of expanded.
s. New application-callable function: rl_pending_signal(): returns the signal
number of any signal readline has caught but not yet handled.
t. New application-settable variable: rl_persistent_signal_handlers: if set
to a non-zero value, readline will enable the readline-6.2 signal handler
behavior in callback mode: handlers are installed when
rl_callback_handler_install is called and removed removed when a complete
line has been read.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.3, and the
previous version, readline-6.2.
1. Changes to Readline
a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
commands to work on the entire line.
b. Fixed a bug that caused redisplay problems with prompts longer than 128
characters and history searches.
c. Fixed a bug that caused readline to try and run code to modify its idea
of the screen size in a signal handler context upon receiving a SIGWINCH.
d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
of an individual call top readline().
e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
redisplay to mishandle zero-width combining characters.
f. Fixed a bug that caused readline to `forget' part of a key sequence when
a multiple-key sequence caused it to break out of an incremental search.
g. Fixed bugs that caused readline to execute code in a signal handler
context if interrupted while reading from the file system during completion.
h. Fixed a bug that caused readline to `forget' part of a key sequence when
reading an unbound multi-character key sequence.
i. Fixed a bug that caused Readline's signal handlers to be installed beyond
the bounds of a single call to readline().
j. Fixed a bug that caused the `.' command to not redo the most recent `R'
command in vi mode.
k. Fixed a bug that caused ignoring case in completion matches to result in
readline using the wrong match.
l. Paren matching now works in vi insert mode.
m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
work together.
n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
in vi editing mode.
o. Fixed a bug that caused the filename comparison code to not compare
multibyte characters correctly when using case-sensitive or case-mapping
comparisons.
p. Fixed the input reading loop to call the input hook function only when there
is no terminal input available.
q. Fixed a bug that caused binding a macro to a multi-character key sequence
where the sequence and macro value share a common prefix to not perform
the macro replacement.
r. Fixed several redisplay errors with multibyte characters and prompts
containing invisible characters when using horizontal scrolling.
s. Fixed a bug that caused redisplay errors when trying to overwrite
existing characters using multibyte characters.
t. Fixed a bug in vi mode that caused the arrow keys to set the saved last
vi-mode command to the wrong value.
u. Fixed a bug that caused double-quoted strings to be scanned incorrectly
when being used as the value of a readline variable assignment.
v. Fixed a bug with vi mode that prevented `.' from repeating a command
entered on a previous line (command).
w. Fixed a bug that could cause completion to core dump if it was interrupted
by a signal.
x. Fixed a bug that could cause readline to crash and seg fault attempting to
expand an empty history entry.
y. Fixed a bug that caused display problems with multi-line prompts containing
invisible characters on multiple lines.
z. Fixed a bug that caused effects made by undoing changes to a history line to
be discarded.
2. New Features in Readline
a. Readline is now more responsive to SIGHUP and other fatal signals when
reading input from the terminal or performing word completion but no
longer attempts to run any not-allowable functions from a signal handler
context.
b. There are new bindable commands to search the history for the string of
characters between the beginning of the line and the point
(history-substring-search-forward, history-substring-search-backward)
c. Readline allows quoted strings as the values of variables when setting
them with `set'. As a side effect, trailing spaces and tabs are ignored
when setting a string variable's value.
d. The history library creates a backup of the history file when writing it
and restores the backup on a write error.
e. New application-settable variable: rl_filename_stat_hook: a function called
with a filename before using it in a call to stat(2). Bash uses it to
expand shell variables so things like $HOME/Downloads have a slash
appended.
f. New bindable function `print-last-kbd-macro', prints the most-recently-
defined keyboard macro in a reusable format.
g. New user-settable variable `colored-stats', enables use of colored text
to denote file types when displaying possible completions (colored analog
of visible-stats).
h. New user-settable variable `keyseq-timout', acts as an inter-character
timeout when reading input or incremental search strings.
i. New application-callable function: rl_clear_history. Clears the history list
and frees all readline-associated private data.
j. New user-settable variable, show-mode-in-prompt, adds a characters to the
beginning of the prompt indicating the current editing mode.
k. New application-settable variable: rl_input_available_hook; function to be
called when readline needs to check whether there is data available on its
input source. The default hook checks rl_instream.
l. Readline calls an application-set event hook (rl_signal_event_hook) after
it gets a signal while reading input (read returns -1/EINTR but readline
does not handle the signal immediately) to allow the application to handle
or otherwise note it. Not currently called for SIGHUP or SIGTERM.
m. If the user-settable variable `history-size' is set to a value less than
0, the history list size is unlimited.
n. When creating shared libraries on Mac OS X, the pathname written into the
library (install_name) no longer includes the minor version number.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.2,
and the previous version, readline-6.1.
1. Changes to Readline
a. Fixed a bug that caused the unconverted filename to be added to the list of
completions when the application specified filename conversion functions.
b. Fixed a bug that caused the wrong filename to be passed to opendir when the
application has specified a filename dequoting function.
c. Fixed a bug when repeating a character search in vi mode in the case where
there was no search to repeat.
d. When show-all-if-ambiguous is set, the completion routines no longer insert
a common match prefix that is shorter than the text being completed.
e. The full set of vi editing commands may now be used in callback mode.
f. Fixed a bug that caused readline to not update its idea of the terminal
dimensions while running in `no-echo' mode.
h. Fixed a bug that caused readline to dump core if an application called
rl_prep_terminal without setting rl_instream.
i. Fixed a bug that caused meta-prefixed characters bound to incremental
search forward or backward to not be recognized if they were typed
subsequently.
j. The incremental search code treats key sequences that map to the same
functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
k. Fixed a bug in menu-complete that caused it to misbehave with large
negative argument.
l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
at the end of the line.
m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
as if it were a negative argument.
n. Fixed a bug that caused directory names in words to be completed to not
be dequoted correctly.
2. New Features in Readline
a. The history library does not try to write the history filename in the
current directory if $HOME is unset. This closes a potential security
problem if the application does not specify a history filename.
b. New bindable variable `completion-display-width' to set the number of
columns used when displaying completions.
c. New bindable variable `completion-case-map' to cause case-insensitive
completion to treat `-' and `_' as identical.
d. There are new bindable vi-mode command names to avoid readline's case-
insensitive matching not allowing them to be bound separately.
e. New bindable variable `menu-complete-display-prefix' causes the menu
completion code to display the common prefix of the possible completions
before cycling through the list, instead of after.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.1,
and the previous version, readline-6.0.
1. Changes to Readline
a. The SIGWINCH signal handler now avoids calling the redisplay code if
one arrives while in the middle of redisplay.
b. Changes to the timeout code to make sure that timeout values greater
than one second are handled better.
c. Fixed a bug in the redisplay code that was triggered by a prompt
containing invisible characters exactly the width of the screen.
d. Fixed a bug in the redisplay code encountered when running in horizontal
scroll mode.
e. Fixed a bug that prevented menu completion from properly completing
filenames.
f. Fixed a redisplay bug caused by a multibyte character causing a line to
wrap.
g. Fixed a bug that caused key sequences of two characters to not be
recognized when a longer sequence identical in the first two characters
was bound.
h. Fixed a bug that caused history expansion to be attempted on $'...'
single-quoted strings.
i. Fixed a bug that caused incorrect redisplay when the prompt contained
multibyte characters in an `invisible' sequence bracketed by \[ and
\].
j. Fixed a bug that caused history expansion to short-circuit after
encountering a multibyte character.
k. Fixed a bug that caused applications using the callback interface to not
react to SIGINT (or other signals) until another character arrived.
2. New Features in Readline
a. New bindable function: menu-complete-backward.
b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
and C-p to menu-complete-backward.
c. When in vi command mode, repeatedly hitting ESC now does nothing, even
when ESC introduces a bound key sequence. This is closer to how
historical vi behaves.
d. New bindable function: skip-csi-sequence. Can be used as a default to
consume key sequences generated by keys like Home and End without having
to bind all keys.
e. New application-settable function: rl_filename_rewrite_hook. Can be used
to rewrite or modify filenames read from the file system before they are
compared to the word to be completed.
f. New bindable variable: skip-completed-text, active when completing in the
middle of a word. If enabled, it means that characters in the completion
that match characters in the remainder of the word are "skipped" rather
than inserted into the line.
g. The pre-readline-6.0 version of menu completion is available as
"old-menu-complete" for users who do not like the readline-6.0 version.
h. New bindable variable: echo-control-characters. If enabled, and the
tty ECHOCTL bit is set, controls the echoing of characters corresponding
to keyboard-generated signals.
i. New bindable variable: enable-meta-key. Controls whether or not readline
sends the smm/rmm sequences if the terminal indicates it has a meta key
that enables eight-bit characters.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.0,
and the previous version, readline-5.2.
1. Changes to Readline
a. Fixed a number of redisplay errors in environments supporting multibyte
characters.
b. Fixed bugs in vi command mode that caused motion commands to inappropriately
set the mark.
c. When using the arrow keys in vi insertion mode, readline allows movement
beyond the current end of the line (unlike command mode).
d. Fixed bugs that caused readline to loop when the terminal has been taken
away and reads return -1/EIO.
e. Fixed bugs in redisplay occurring when displaying prompts containing
invisible characters.
f. Fixed a bug that caused the completion append character to not be reset to
the default after an application-specified completion function changed it.
g. Fixed a problem that caused incorrect positioning of the cursor while in
emacs editing mode when moving forward at the end of a line while using
a locale supporting multibyte characters.
h. Fixed an off-by-one error that caused readline to drop every 511th
character of buffered input.
i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
j. Fixed redisplay bugs caused by multiline prompts with invisible characters
or no characters following the final newline.
k. Fixed redisplay bug caused by prompts consisting solely of invisible
characters.
l. Fixed a bug in the code that buffers characters received very quickly in
succession which caused characters to be dropped.
m. Fixed a bug that caused readline to reference uninitialized data structures
if it received a SIGWINCH before completing initialization.
n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
and therefore unrepeatable.
o. Fixed a bug that caused readline to disable echoing when it was being used
with an output file descriptor that was not a terminal.
p. Readline now blocks SIGINT while manipulating internal data structures
during redisplay.
q. Fixed a bug in redisplay that caused readline to segfault when pasting a
very long line (over 130,000 characters).
r. Fixed bugs in redisplay when using prompts with no visible printing
characters.
s. Fixed a bug that caused redisplay errors when using prompts with invisible
characters and numeric arguments to a command in a multibyte locale.
t. Fixed a bug that caused redisplay errors when using prompts with invisible
characters spanning more than two physical screen lines.
2. New Features in Readline
a. A new variable, rl_sort_completion_matches; allows applications to inhibit
match list sorting (but beware: some things don't work right if
applications do this).
b. A new variable, rl_completion_invoking_key; allows applications to discover
the key that invoked rl_complete or rl_menu_complete.
c. The functions rl_block_sigint and rl_release_sigint are now public and
available to calling applications who want to protect critical sections
(like redisplay).
d. The functions rl_save_state and rl_restore_state are now public and
available to calling applications; documented rest of readline's state
flag values.
e. A new user-settable variable, `history-size', allows setting the maximum
number of entries in the history list.
f. There is a new implementation of menu completion, with several improvements
over the old; the most notable improvement is a better `completions
browsing' mode.
g. The menu completion code now uses the rl_menu_completion_entry_function
variable, allowing applications to provide their own menu completion
generators.
h. There is support for replacing a prefix of a pathname with a `...' when
displaying possible completions. This is controllable by setting the
`completion-prefix-display-length' variable. Matches with a common prefix
longer than this value have the common prefix replaced with `...'.
i. There is a new `revert-all-at-newline' variable. If enabled, readline will
undo all outstanding changes to all history lines when `accept-line' is
executed.
-------------------------------------------------------------------------------
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 documentation 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
.
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 retrieved 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//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

'configure' configures readline 8.3 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print 'checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for '--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or '..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc. You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]

Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CPP C preprocessor
Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.
