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. |
