-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.
-
-2. New Features in Readline
-
-a. The history truncation code now uses the same error recovery mechansim 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.
-
--------------------------------------------------------------------------------
-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.
