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.

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.

Readline no longer tries to read ahead more than one line of input, even - when more is available. - -e. Fixed the code that adjusts the point to not mishandle null wide - characters. - -f. Fixed a bug in the history expansion `g' modifier that caused it to skip - every other match. - -g. Fixed a bug that caused the prompt to overwrite previous output when the - output doesn't contain a newline and the locale supports multibyte - characters. This same change fixes the problem of readline redisplay - slowing down dramatically as the line gets longer in multibyte locales. - -h. History traversal with arrow keys in vi insertion mode causes the cursor - to be placed at the end of the new line, like in emacs mode. - -i. The locale initialization code does a better job of using the right - precedence and defaulting when checking the appropriate environment - variables. - -j. Fixed the history word tokenizer to handle <( and >( better when used as - part of bash. - -k. The overwrite mode code received several bug fixes to improve undo. - -l. Many speedups to the multibyte character redisplay code. - -m. The callback character reading interface should not hang waiting to read - keyboard input. - -n. Fixed a bug with redoing vi-mode `s' command. - -o.

Fixed a bug that could cause garbage to be inserted in the buffer when - changing character case in vi mode when using a multibyte locale. - -q. Fixed a bug in the redisplay code that caused problems on systems - supporting multibyte characters when moving between history lines when the - new line has more glyphs but fewer bytes. - -r. Undo and redo now work better after exiting vi insertion mode. - -s. Make sure system calls are restarted after a SIGWINCH is received using - SA_RESTART. - -t. Improvements to the code that displays possible completions when using - multibyte characters. - -u. Fixed a problem when parsing nested if statements in inputrc files. - -v. The completer now takes multibyte characters into account when looking for - quoted substrings on which to perform completion. - -w. The history search functions now perform better bounds checking on the - history list. - -x. Change to history expansion functions to treat `^' as equivalent to word - one, as the documention states. - -y. Some changes to the display code to improve display and redisplay of - multibyte characters. - -z. Changes to speed up the multibyte character redisplay code. - -aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the - last character of a word if invoked while point was on the word's - next-to-last character. - -bb. Fixed a bug that could cause incorrect filename quoting when - case-insensitive completion was enabled and the word being completed - contained backslashes quoting word break characters. - -cc. Fixed a bug in redisplay triggered when the prompt string contains - invisible characters. - -dd. Fixed some display (and other) bugs encountered in multibyte locales - when a non-ascii character was the last character on a line. - -ee. Fixed some display bugs caused by multibyte characters in prompt strings. - -ff. Fixed a problem with history expansion caused by non-whitespace characters - used as history word delimiters. - -gg.

Improvements to the code that expands and displays prompt strings - containing multibyte characters. - -ii. Fixed a problem with vi-mode not correctly remembering the numeric argument - to the last `c'hange command for later use with `.'. - -jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work - incorrectly. - -kk. Fixed a problem in vi-mode that caused the last text modification command - to not be remembered across different command lines. - -ll. Fixed problems with changing characters and changing case at the end of - the line. - -mm. Fixed a problem with readline saving the contents of the current line - before beginning a non-interactive search. - -nn. Fixed a problem with EOF detection when using rl_event_hook. - -oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric - arguments. - -2. 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. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-4.3, -and the previous version, readline-4.2a. - -1. Changes to Readline - -a. Fixed output of comment-begin character when listing variable values. - -b. Added some default key bindings for common escape sequences produced by - HOME and END keys. - -c. Fixed the mark handling code to be more emacs-compatible. - -d. A bug was fixed in the code that prints possible completions to keep it - from printing empty strings in certain circumstances. - -e. Change the key sequence printing code to print ESC as M\- if ESC is a - meta-prefix character -- it's easier for users to understand than \e. - -f. Fixed unstifle_history() to return values that match the documentation. - -g. Fixed the event loop (rl_event_hook) to handle the case where the input - file descriptor is invalidated. - -h. Fixed the prompt display code to work better when the application has a - custom redisplay function. - -i. Changes to make reading and writing the history file a little faster, and - to cope with huge history files without calling abort(3) from xmalloc. - -j. The vi-mode `S' and `s' commands are now undone correctly. - -k. Fixed a problem which caused the display to be messed up when the last - line of a multi-line prompt (possibly containing invisible characters) - was longer than the screen width. - -2. New Features in Readline - -a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both - be bound to readline functions. Now the arrow keys may be used in vi - insert mode. - -b. When listing completions, and the number of lines displayed is more than - the screen length, readline uses an internal pager to display the results. - This is controlled by the `page-completions' variable (default on). - -c. New code to handle editing and displaying multibyte characters. - -d. The behavior introduced in bash-2.05a of deciding whether or not to - append a slash to a completed name that is a symlink to a directory has - been made optional, controlled by the `mark-symlinked-directories' - variable (default is the 2.05a behavior). - -e. The `insert-comment' command now acts as a toggle if given a numeric - argument: if the first characters on the line don't specify a - comment, insert one; if they do, delete the comment text - -f. New application-settable completion variable: - rl_completion_mark_symlink_dirs, allows an application's completion - function to temporarily override the user's preference for appending - slashes to names which are symlinks to directories. - -g. New function available to application completion functions: - rl_completion_mode, to tell how the completion function was invoked - and decide which argument to supply to rl_complete_internal (to list - completions, etc.). - -h. Readline now has an overwrite mode, toggled by the `overwrite-mode' - bindable command, which could be bound to `Insert'. - -i. New application-settable completion variable: - rl_completion_suppress_append, inhibits appending of - rl_completion_append_character to completed words. - -j. New key bindings when reading an incremental search string: ^W yanks - the currently-matched word out of the current line into the search - string; ^Y yanks the rest of the current line into the search string, - DEL or ^H deletes characters from the search string. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-4.2a, -and the previous version, readline-4.2. - -1. Changes to Readline - -a. More `const' and type casting fixes. - -b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer - overflow problems. - -c. The completion code no longer appends a `/' or ` ' to a match when - completing a symbolic link that resolves to a directory name, unless - the match does not add anything to the word being completed. This - means that a tab will complete the word up to the full name, but not - add anything, and a subsequent tab will add a slash. - -d. Fixed a trivial typo that made the vi-mode `dT' command not work. - -e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert. - -f. Fixed the tty code so that ^V works more than once. - -g. Changed the use of __P((...)) for function prototypes to PARAMS((...)) - because the use of __P in typedefs conflicted g++ and glibc. - -h. The completion code now attempts to do a better job of preserving the - case of the word the user typed if ignoring case in completions. - -i. Readline defaults to not echoing the input and lets the terminal - initialization code enable echoing if there is a controlling terminal. - -j. The key binding code now processes only two hex digits after a `\x' - escape sequence, and the documentation was changed to note that the - octal and hex escape sequences result in an eight-bit value rather - than strict ASCII. - -k. Fixed a few places where negative array subscripts could have occurred. - -l. Fixed the vi-mode code to use a better method to determine the bounds of - the array used to hold the marks, and to avoid out-of-bounds references. - -m. Fixed the defines in chardefs.h to work better when chars are signed. - -n. Fixed configure.in to use the new names for bash autoconf macros. - -o. Readline no longer attempts to define its own versions of some ctype - macros if they are implemented as functions in libc but not as macros in - <ctype.h>. - -p. Fixed a problem where rl_backward could possibly set point to before - the beginning of the line. - -q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause - include file problems. - -2. New Features in Readline - -a. Added extern declaration for rl_get_termcap to readline.h, making it a - public function (it was always there, just not in readline.h). - -b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402, - RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2. - -c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION. - -d. New bindable boolean readline variable: match-hidden-files. Controls - completion of files beginning with a `.' (on Unix). Enabled by default. - -e. The history expansion code now allows any character to terminate a - `:first-' modifier, like csh. - -f. The incremental search code remembers the last search string and uses - it if ^R^R is typed without a search string. - -h. New bindable variable `history-preserve-point'. If set, the history - code attempts to place the user at the same location on each history - line retrived with previous-history or next-history. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-4.2, -and the previous version, readline-4.1. - -1. Changes to Readline - -a. When setting the terminal attributes on systems using `struct termio', - readline waits for output to drain before changing the attributes. - -b. A fix was made to the history word tokenization code to avoid attempts to - dereference a null pointer. - -c. Readline now defaults rl_terminal_name to $TERM if the calling application - has left it unset, and tries to initialize with the resultant value. - -d. Instead of calling (*rl_getc_function)() directly to get input in certain - places, readline now calls rl_read_key() consistently. - -e. Fixed a bug in the completion code that allowed a backslash to quote a - single quote inside a single-quoted string. - -f. rl_prompt is no longer assigned directly from the argument to readline(), - but uses memory allocated by readline. This allows constant strings to - be passed to readline without problems arising when the prompt processing - code wants to modify the string. - -g. Fixed a bug that caused non-interactive history searches to return the - wrong line when performing multiple searches backward for the same string. - -h. Many variables, function arguments, and function return values are now - declared `const' where appropriate, to improve behavior when linking with - C++ code. - -i. The control character detection code now works better on systems where - `char' is unsigned by default. - -j. The vi-mode numeric argument is now capped at 999999, just like emacs mode. - -k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been - replaced with a set of specific prototyped typedefs, though they are - still in the readline header files for backwards compatibility. - -m. Nearly all of the (undocumented) internal global variables in the library - now have an _rl_ prefix -- there were a number that did not, like - screenheight, screenwidth, alphabetic, etc. - -n. The ding() convenience function has been renamed to rl_ding(), though the - old function is still defined for backwards compatibility. - -o. The completion convenience functions filename_completion_function, - username_completion_function, and completion_matches now have an rl_ - prefix, though the old names are still defined for backwards compatibility. - -p. The functions shared by readline and bash (linkage is satisfied from bash - when compiling with bash, and internally otherwise) now have an sh_ prefix. - -q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so - that the `soname' contains only the major version number rather than the - major and minor numbers. - -r. Fixed a redisplay bug that occurred when the prompt spanned more than one - physical line and contained invisible characters. - -s. Added a missing `includedir' variable to the Makefile. - -t. When installing the shared libraries, make sure symbolic links are relative. - -u. Added configure test so that it can set `${MAKE}' appropriately. - -v. Fixed a bug in rl_forward that could cause the point to be set to before - the beginning of the line in vi mode. - -w. Fixed a bug in the callback read-char interface to make it work when a - readline function pushes some input onto the input stream with - rl_execute_next (like the incremental search functions). - -x. Fixed a file descriptor leak in the history file manipulation code that - was tripped when attempting to truncate a non-regular file (like - /dev/null). - -y. Changes to make all of the exported readline functions declared in - readline.h have an rl_ prefix (rltty_set_default_bindings is now - rl_tty_set_default_bindings, crlf is now rl_crlf, etc.) - -z. The formatted documentation included in the base readline distribution - is no longer removed on a `make distclean'. - -aa. Some changes were made to avoid gcc warnings with -Wall. - -bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so - `set keymap EMACS' works. - -cc. The history file writing and truncation functions now return a useful - status on error. - -dd. Fixed a bug that could cause applications to dereference a NULL pointer - if a NULL second argument was passed to history_expand(). - -ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero - value, rl_read_key() now immediately returns '\n' (which is assumed to - be bound to accept-line). - -2. New Features in Readline - -a. The blink timeout for paren matching is now settable by applications, - via the rl_set_paren_blink_timeout() function. - -b. _rl_executing_macro has been renamed to rl_executing_macro, which means - it's now part of the public interface. - -c. Readline has a new variable, rl_readline_state, which is a bitmap that - encapsulates the current state of the library; intended for use by - callbacks and hook functions. - -d. rlfe has a new -l option to log input and output (-a appends to logfile), - a new -n option to set the readline application name, and -v and -h - options for version and help information. - -e. rlfe can now perform filename completion for the inferior process if the - OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the - inferior's current working directory. - -f. A new file, rltypedefs.h, contains the new typedefs for function pointers - and is installed by `make install'. - -g. New application-callable function rl_set_prompt(const char *prompt): - expands its prompt string argument and sets rl_prompt to the result. - -h. New application-callable function rl_set_screen_size(int rows, int cols): - public method for applications to set readline's idea of the screen - dimensions. - -i. The history example program (examples/histexamp.c) is now built as one - of the examples. - -j. The documentation has been updated to cover nearly all of the public - functions and variables declared in readline.h. - -k. New function, rl_get_screen_size (int *rows, int *columns), returns - readline's idea of the screen dimensions. - -l. The timeout in rl_gather_tyi (readline keyboard input polling function) - is now settable via a function (rl_set_keyboard_input_timeout()). - -m. Renamed the max_input_history variable to history_max_entries; the old - variable is maintained for backwards compatibility. - -n. The list of characters that separate words for the history tokenizer is - now settable with a variable: history_word_delimiters. The default - value is as before. - -o. There is a new history.3 manual page documenting the history library. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-4.1, -and the previous version, readline-4.0. - -1. Changes to Readline - -a. Changed the HTML documents so that the table-of-contents is no longer - a separate file. - -b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x, - OSF/1. - -c. The shared library major and minor versions are now constructed - automatically by configure and substituted into the makefiles. - -d. It's now possible to install the shared libraries separately from the - static libraries. - -e. The history library tries to truncate the history file only if it is a - regular file. - -f. A bug that caused _rl_dispatch to address negative array indices on - systems with signed chars was fixed. - -g. rl-yank-nth-arg now leaves the history position the same as when it was - called. - -h. Changes to the completion code to handle MS-DOS drive-letter:pathname - filenames. - -i. Completion is now case-insensitive by default on MS-DOS. - -j. Fixes to the history file manipulation code for MS-DOS. - -k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS. - -l. Some fixes were made to the redisplay code for better operation on MS-DOS. - -m. The quoted-insert code will now insert tty special chars like ^C. - -n. A bug was fixed that caused the display code to reference memory before - the start of the prompt string. - -o. More support for __EMX__ (OS/2). - -p. A bug was fixed in readline's signal handling that could cause infinite - recursion in signal handlers. - -q. A bug was fixed that caused the point to be less than zero when rl_forward - was given a very large numeric argument. - -r. The vi-mode code now gets characters via the application-settable value - of rl_getc_function rather than calling rl_getc directly. - -s. The history file code now uses O_BINARY mode when reading and writing - the history file on cygwin32. - -t. Fixed a bug in the redisplay code for lines with more than 256 line - breaks. - -u. A bug was fixed which caused invisible character markers to not be - stripped from the prompt string if the terminal was in no-echo mode. - -v. Readline no longer tries to get the variables it needs for redisplay - from the termcap entry if the calling application has specified its - own redisplay function. Readline treats the terminal as `dumb' in - this case. - -w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape - sequences is redrawn correctly. - -x. Changes to the install and install-shared targets so that the libraries - and header files are installed separately. - -2. New Features in Readline - -a. A new Readline `user manual' is in doc/rluserman.texinfo. - -b. Parentheses matching is now always compiled into readline, and enabled - or disabled when the value of the `blink-matching-paren' variable is - changed. - -c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename. - -d. MS-DOS systems now use ~/_history as the default history file. - -e. history-search-{forward,backward} now leave the point at the end of the - line when the string to search for is empty, like - {reverse,forward}-search-history. - -f. history-search-{forward,backward} now leave the last history line found - in the readline buffer if the second or subsequent search fails. - -g. New function for use by applications: rl_on_new_line_with_prompt, used - when an application displays the prompt itself before calling readline(). - -h. New variable for use by applications: rl_already_prompted. An application - that displays the prompt itself before calling readline() must set this to - a non-zero value. - -i. A new variable, rl_gnu_readline_p, always 1. The intent is that an - application can verify whether or not it is linked with the `real' - readline library or some substitute. - -j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program - is included in the examples subdirectory, though it is not built - by default. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-4.0, -and the previous version, readline-2.2. - -1. Changes to Readline - -a. The version number is now 4.0, to match the major and minor version - numbers on the shared readline and history libraries. Future - releases will maintain the identical numbering. - -b. Fixed a typo in the `make install' recipe that copied libreadline.a - to libhistory.old right after installing it. - -c. The readline and history info files are now installed out of the source - directory if they are not found in the build directory. - -d. The library no longer exports a function named `savestring' -- backwards - compatibility be damned. - -e. There is no longer any #ifdef SHELL code in the source files. - -f. Some changes were made to the key binding code to fix memory leaks and - better support Win32 systems. - -g. Fixed a silly typo in the paren matching code -- it's microseconds, not - milliseconds. - -h. The readline library should be compilable by C++ compilers. - -i. The readline.h public header file now includes function prototypes for - all readline functions, and some changes were made to fix errors in the - source files uncovered by the use of prototypes. - -j. The maximum numeric argument is now clamped at 1000000. - -k. Fixes to rl_yank_last_arg to make it behave better. - -l. Fixed a bug in the display code that caused core dumps if the prompt - string length exceeded 1024 characters. - -m. The menu completion code was fixed to properly insert a single completion - if there is only one match. - -n. A bug was fixed that caused the display code to improperly display tabs - after newlines. - -o. A fix was made to the completion code in which a typo caused the wrong - value to be passed to the function that computed the longest common - prefix of the list of matches. - -p. The completion code now checks the value of rl_filename_completion_desired, - which is set by application-supplied completion functions to indicate - that filename completion is being performed, to decide whether or not to - call an application-supplied `ignore completions' function. - -q. Code was added to the history library to catch history substitutions - using `&' without a previous history substitution or search having been - performed. - - -2. New Features in Readline - -a. There is a new script, support/shobj-conf, to do system-specific shared - object and library configuration. It generates variables for configure - to substitute into makefiles. The README file provides a detailed - explanation of the shared library creation process. - -b. Shared libraries and objects are now built in the `shlib' subdirectory. - There is a shlib/Makefile.in to control the build process. `make shared' - from the top-level directory is still the right way to build shared - versions of the libraries. - -c. rlconf.h is now installed, so applications can find out which features - have been compiled into the installed readline and history libraries. - -d. rlstdc.h is now an installed header file. - -e. Many changes to the signal handling: - o Readline now catches SIGQUIT and cleans up the tty before returning; - o A new variable, rl_catch_signals, is available to application writers - to indicate to readline whether or not it should install its own - signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP, - SIGTTIN, and SIGTTOU; - o A new variable, rl_catch_sigwinch, is available to application - writers to indicate to readline whether or not it should install its - own signal handler for SIGWINCH, which will chain to the calling - applications's SIGWINCH handler, if one is installed; - o There is a new function, rl_free_line_state, for application signal - handlers to call to free up the state associated with the current - line after receiving a signal; - o There is a new function, rl_cleanup_after_signal, to clean up the - display and terminal state after receiving a signal; - o There is a new function, rl_reset_after_signal, to reinitialize the - terminal and display state after an application signal handler - returns and readline continues - -f. There is a new function, rl_resize_terminal, to reset readline's idea of - the screen size after a SIGWINCH. - -g. New public functions: rl_save_prompt and rl_restore_prompt. These were - previously private functions with a `_' prefix. These functions are - used when an application wants to write a message to the `message area' - with rl_message and have the prompt restored correctly when the message - is erased. - -h. New function hook: rl_pre_input_hook, called just before readline starts - reading input, after initialization. - -i. New function hook: rl_display_matches_hook, called when readline would - display the list of completion matches. The new function - rl_display_match_list is what readline uses internally, and is available - for use by application functions called via this hook. - -j. New bindable function, delete-char-or-list, like tcsh. - -k. A new variable, rl_erase_empty_line, which, if set by an application using - readline, will cause readline to erase, prompt and all, lines on which the - only thing typed was a newline. - -l. There is a new script, support/shlib-install, to install and uninstall - the shared readline and history libraries. - -m. A new bindable variable, `isearch-terminators', which is a string - containing the set of characters that should terminate an incremental - search without being executed as a command. - -n. A new bindable function, forward-backward-delete-char. - -------------------------------------------------------------------------------- -This document details the changes between this version, readline-2.2, -and the previous version, readline-2.1. - -1. Changes to Readline - -a. Added a missing `extern' to a declaration in readline.h that kept - readline from compiling cleanly on some systems. - -b. The history file is now opened with mode 0600 when it is written for - better security. - -c. Changes were made to the SIGWINCH handling code so that prompt redisplay - is done better. - -d. ^G now interrupts incremental searches correctly. - -e. A bug that caused a core dump when the set of characters to be quoted - when completing words was empty was fixed. - -f. Fixed a problem in the readline test program rltest.c that caused a core - dump. - -g. The code that handles parser directives in inputrc files now displays - more error messages. - -h. The history expansion code was fixed so that the appearance of the - history comment character at the beginning of a word inhibits history - expansion for that word and the rest of the input line. - -i. The code that prints completion listings now behaves better if one or - more of the filenames contains non-printable characters. - -j. The time delay when showing matching parentheses is now 0.5 seconds. - - -2. New Features in Readline - -a. There is now an option for `iterative' yank-last-arg handline, so a user - can keep entering `M-.', yanking the last argument of successive history - lines. - -b. New variable, `print-completions-horizontally', which causes completion - matches to be displayed across the screen (like `ls -x') rather than up - and down the screen (like `ls'). - -c. New variable, `completion-ignore-case', which causes filename completion - and matching to be performed case-insensitively. - -d. There is a new bindable command, `magic-space', which causes history - expansion to be performed on the current readline buffer and a space to - be inserted into the result. - -e. There is a new bindable command, `menu-complete', which enables tcsh-like - menu completion (successive executions of menu-complete insert a single - completion match, cycling through the list of possible completions). - -f. There is a new bindable command, `paste-from-clipboard', for use on Win32 - systems, to insert the text from the Win32 clipboard into the editing - buffer. - -g. The key sequence translation code now understands printf-style backslash - escape sequences, including \NNN octal escapes. These escape sequences - may be used in key sequence definitions or macro values. - -h. An `$include' inputrc file parser directive has been added. |
