-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.
-
-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.
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.
+
2. New Features in Readline
a. There is now an HS_HISTORY_VERSION containing the version number of the
h. rl_completer_word_break_characters is now `const char *' like
rl_basic_word_break_characters.
-i. The non-incremental history searches now leave the current history offset
- at the position of the last matching history entry, like incremental search.
-
-j. Readline looks in $LS_COLORS for a custom filename extension
+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.
