-This is a terse description of the new features added to readline-7.0 since
-the release of readline-6.3.
+This is a terse description of the new features added to readline-6.2 since
+the release of readline-6.1.
-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.
-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. New bindable variable `completion-display-width' to set the number of
+ columns used when displaying completions.
-b. There is a new bindable variable, `enable-bracketed-paste', which enables
- support for a terminal's bracketed paste mode.
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
-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. There are new bindable vi-mode command names to avoid readline's case-
+ insensitive matching not allowing them to be bound separately.
-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 is a terse description of the new features added to readline-6.3 since
-the release of readline-6.2.
-
-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 detects there is data available on its input file
- descriptor.
-
-l. Readline calls an application-set event hook (rl_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.
-
-m. If the user-settable variable `history-size' is set to a value less than
- 0, the history list size is unlimited.
-
-n. New application-settable variable: rl_signal_event_hook; function that is
- called when readline is reading terminal input and read(2) is interrupted
- by a signal. Currently not called for SIGHUP or SIGTERM.
-
--------------------------------------------------------------------------------
-This is a terse description of the new features added to readline-6.1 since
-the release of readline-6.0.
-
-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 rewite 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 is a terse description of the new features added to readline-6.0 since
-the release of readline-5.2.
-
-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 is a terse description of the new features added to readline-5.2 since
-the release of readline-5.1.
-
-New Features in Readline
-
-a. Calling applications can now set the keyboard timeout to 0, allowing
- poll-like behavior.
-
-b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
- the default last-ditch startup file.
-
-c. The history file reading functions now allow windows-like \r\n line
- terminators.
-
--------------------------------------------------------------------------------
-This is a terse description of the new features added to readline-5.1 since
-the release of readline-5.0.
-
-New Features in Readline
-
-a. The key sequence sent by the keypad `delete' key is now automatically
- bound to delete-char.
-
-b. A negative argument to menu-complete now cycles backward through the
- completion list.
-
-c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
- readline will bind the terminal special characters to their readline
- equivalents when it's called (on by default).
-
-d. New bindable command: vi-rubout. Saves deleted text for possible
- reinsertion, as with any vi-mode `text modification' command; `X' is bound
- to this in vi command mode.
-
-e. If the rl_completion_query_items is set to a value < 0, readline never
- asks the user whether or not to view the possible completions.
-
-f. New application-callable auxiliary function, rl_variable_value, returns
- a string corresponding to a readline variable's value.
-
-g. When parsing inputrc files and variable binding commands, the parser
- strips trailing whitespace from values assigned to boolean variables
- before checking them.
-
-h. A new external application-controllable variable that allows the LINES
- and COLUMNS environment variables to set the window size regardless of
- what the kernel returns.
-
-
--------------------------------------------------------------------------------
-This is a terse description of the new features added to readline-5.0 since
-the release of readline-4.3.
-
-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.
+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.
