Changes to Readline + +a. Fixed a bug that caused multiliine prompts to be wrapped and displayed + incorrectly. + +b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current + line correctly. + +c. Fixed a problem in computing the number of invisible characters on the first + line of a prompt whose length exceeds the screen width. + +d. Fixed vi-mode searching so that failure preserves the current line rather + than the last line in the history list. + +e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +g. Fixed multiple bugs in the redisplay of multibyte characters: displaying + prompts longer than the screen width containing multibyte characters, + +h. Fix the calculation of the number of physical characters in the prompt + string when it contains multibyte characters. + +i. A non-zero value for the `rl_complete_suppress_append' variable now causes + no `/' to be appended to a directory name. + +j. Fixed forward-word and backward-word to work when words contained + multibyte characters. + +k. Fixed a bug in finding the delimiter of a `?' substring when performing + history expansion in a locale that supports multibyte characters. + +l. Fixed a memory leak caused by not freeing the timestamp in a history entry. + +m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting + of the `convert-meta' variable. + +n. Fixed saving and restoring primary prompt when prompting for incremental + and non-incremental searches; search prompts now display multibyte + characters correctly. + +o. Fixed a bug that caused keys originally bound to self-insert but shadowed + by a multi-character key sequence to not be inserted. + +p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't + dereferenced if NULL (matching the documentation). + +q. Extensive changes to readline to add enough state so that commands + requiring additional characters (searches, multi-key sequences, numeric + arguments, commands requiring an additional specifier character like + vi-mode change-char, etc.) work without synchronously waiting for + additional input. + +r. Lots of changes so readline builds and runs on MinGW. + +s. Readline no longer tries to modify the terminal settings when running in + callback mode. + +t. The Readline display code no longer sets the location of the last invisible + character in the prompt if the \[\] sequence is empty. + +u. The `change-case' command now correctly changes the case of multibyte + characters. + +v. Changes to the shared library construction scripts to deal with Windows + DLL naming conventions for Cygwin. + +w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed + SIGWINCH. + +x. Fixed the non-incremental search code in vi mode to dispose of any current + undo list when copying a line from the history into the current editing + buffer. + +y. Fixed a bug that caused reversing the incremental search direction to + not work correctly. + +z. Fixed the vi-mode `U' command to only undo up to the first time insert mode + was entered, as Posix specifies. + +aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong + place. + +bb. Fixed a redisplay bug caused by moving the cursor vertically to a line + with invisible characters in the prompt in a multibyte locale. + +cc. Fixed a bug that could cause the terminal special chars to be bound in the + wrong keymap in vi mode. + +2. 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. The `C-w' binding in incremental search now understands multibyte + characters. + +g. New application-callable auxiliary function, rl_variable_value, returns + a string corresponding to a readline variable's value. + +h. When parsing inputrc files and variable binding commands, the parser + strips trailing whitespace from values assigned to boolean variables + before checking them. + +i. 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 document details the changes between this version, readline-5.0, and the previous version, readline-4.3. |
