Fixed a bug in clearing the visible line structure before redisplay. + +b. Fix a bug where setlocale(3) returning NULL caused a crash. + +c. Fixed signal checking in callback mode to handle signals that arrive before + readline restore's the application's signal handlers. + +d. Fixed a bug with word completion where the directory name needs to be + dequoted and tilde-expanded. + +e. Fixed a bug that caused compilation to fail on systems with select but not + pselect. + +f. System-specific changes for: WIN32, z/OS, Cygwin, MSYS + +g. Fixed a bug that caused word completion mismatches if the quoted text the + user typed was longer than the unquoted match. + +h. Fixes for freeing undo lists that might appear in history list entries + after non-incremental searches. + +i. Fixes for some errors revealed by address sanitizer. + +j. In vi mode, if an `f' or `F' move command associated with a `c' or `C' + command fails, don't enter insert mode. + +k. Fixed bug with truncating a history file containing timestamps that caused + the timestamp associated with the first history entry not to be written. + +l. Fix vi-mode so that a motion command attached to d/D, y/Y, or t/T must + consume or delete at least one character. + +m. Fix a redisplay error when displaying meta characters as octal sequences + and other C locale issues. + +n. Fix error that caused characters composing an incomplete multibyte + character not to be inserted into the line. + +o. In callback mode, let the application echo the signal characters (e.g., ^C) + when the application's signal handlers are installed. + +p. Added some support for lines that consume more than the physical number of + screen lines. + +q. Make sure dump-variables returns the string values for active-region-start-color + and active-region-end-color if they're set. + +r. Fixes to how characters between 128 and 159 are printed when displaying + macro values (use symbolic notation instead of directly printing the + character). + +s. Don't convert meta characters that contain NULL (\M-\C-@) to actual NULs, + which prematurely terminates the macro value. + +t. Fix typo in the readline color prefix extension that it uses for coloring + filename prefixes when displaying possible completions. + +u. Call the filename rewrite hook on the word being completed before comparing + it against possible completions from the file system to get consistent + strings. + +v. Fix infinite recursion that can happen if someone binds a key that doesn't + have a different upper and lower case represenation to do-lowercase-version. + +w. Check for non-ANSI (dumb) terminals a little more thoroughly. + +x. Don't attempt to history-expand the `quick substitution' character at the + beginning of a line if the application has set the quoting state to single + quotes. + +y. Fix small memory leak if non-incremental or incremental search is + interrupted by a signal. + +z. Loading very large history files should be much faster. + +aa. Retry opening startup files if the open is interrupted by a signal + and is not automatically restarted. + +2. New Features in Readline + +a. Output a newline if there is no prompt and readline reads an empty line. + +b. The history library falls back to stdio when writing the history list if + mmap fails. + +c. New bindable variable `search-ignore-case', causes readline to perform + case-insensitive incremental and non-incremental history searches. + +d. rl_full_quoting_desired: new application-settable variable, causes all + completions to be quoted as if they were filenames. + +e. rl_macro_display_hook: new application-settable function pointer, used if + the application wants to print macro values itself instead of letting + readline do it + +f. rl_reparse_colors: new application-callable function, reparses $LS_COLORS + (presumably after the user changes it) + +g. rl_completion_rewrite_hook: new application-settable function pointer, + called to modify the word being completed before comparing it against + pathnames from the file system. + +h. execute-named-command: a new bindable command that reads the name of a + readline command from the standard input and executes it. Bound to M-x + in emacs mode by default. + +i. Incremental and non-incremental searches now allow ^V/^Q (or, in the former + case, anything bound to quoted-insert) to quote characters in the search + string. + +------------------------------------------------------------------------------- This document details the changes between this version, readline-8.2, and the previous version, readline-8.1. |
