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. +New Features in Readline -b. New bindable variable `completion-display-width' to set the number of - columns used when displaying completions. +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. -c. New bindable variable `completion-case-map' to cause case-insensitive - completion to treat `-' and `_' as identical. +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) -d. There are new bindable vi-mode command names to avoid readline's case- - insensitive matching not allowing them to be bound separately. +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. -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. +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. |
