From 2061b410c77c6fb24503185000f1036ee6896d93 Mon Sep 17 00:00:00 2001 From: bapt Date: Tue, 6 Feb 2018 12:22:42 +0000 Subject: [PATCH] Remove libreadline from the source tree, all consumers but gdb has been switched to libedit long ago, libreadline was built as an internallib for a while and kept only for gdbtui which was broken using libreadline. Since gdb has been mostly deorbitted in all arches, gdbtui was only installed on arm and sparc64, given it has been removed, gdb has been switched to use libedit, no consumers are left for libreadline. Thus this removal --- contrib/libreadline/CHANGELOG | 960 -- contrib/libreadline/CHANGES | 995 -- contrib/libreadline/COPYING | 339 - contrib/libreadline/FREEBSD-upgrade | 13 -

Fixed output of key bindings (like bash `bind -p') to honor the setting of - convert-meta and use \e where appropriate. - -h. Changed the default filename completion function to call the filename - dequoting function if the directory completion hook isn't set. This means - that any directory completion hooks need to dequote the directory name, - since application-specific hooks need to know how the word was quoted, - even if no other changes are made. - -i.

Fixed a bug that caused prompts with invisible characters to be redrawn - multiple times in a multibyte locale. - -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. - -1. Changes to Readline - -a. Fixes to avoid core dumps because of null pointer references in the - multibyte character code. - -b. Fix to avoid infinite recursion caused by certain key combinations. - -c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly. - -d. 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. The code that initializes the terminal tracks changes made to the terminal - special characters with stty(1) (or equivalent), so that these changes - are reflected in the readline bindings. New application-callable function - to make it work: rl_tty_unset_default_bindings(). - -p. 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. Fixed a problem that could cause readline to refer to freed memory when - moving between history lines while doing searches. - -hh. 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 - . - -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//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. diff --git a/contrib/libreadline/COPYING b/contrib/libreadline/COPYING deleted file mode 100644 index 1bf152638784..000000000000 --- a/contrib/libreadline/COPYING +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it.

Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) 19yy - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes some time. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile readline and build the static readline - and history libraries. If supported, the shared readline and history - libraries will be built also. See below for instructions on compiling - the other parts of the distribution. Typing `make everything' will - cause the static and shared libraries (if supported) and the example - programs to be built. - - 3. Type `make install' to install the static readline and history - libraries, the readline include files, the documentation, and, if - supported, the shared readline and history libraries. - - 4. You can remove the created libraries and object files from the - build directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile readline for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the readline developers, and should be used with care. - -The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It -uses those values to create a `Makefile' in the build directory, -and Makefiles in the `doc', `shlib', and `examples' -subdirectories. It also creates a `config.h' file containing -system-dependent definitions. Finally, it creates a shell script -`config.status' that you can run in the future to recreate the -current configuration, a file `config.cache' that saves the -results of its tests to speed up reconfiguring, and a file -`config.log' containing compiler output (useful mainly for -debugging `configure'). - -If you need to do unusual things to compile readline, please try -to figure out how `configure' could check whether to do them, and -mail diffs or instructions to so they can -be considered for the next release. If at some point -`config.cache' contains results you don't want to keep, you may -remove or edit it. - -The file `configure.in' is used to create `configure' by a -program called `autoconf'. You only need `configure.in' if you -want to change it or regenerate `configure' using a newer version -of `autoconf'. The readline `configure.in' requires autoconf -version 2.50 or newer. - -Compilers and Options -===================== - -Some systems require unusual options for compilation or linking that -the `configure' script does not know about. You can give `configure' -initial values for variables by setting them in the environment. Using -a Bourne-compatible shell, you can do that on the command line like -this: - - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure - -Or on systems that have the `env' program, you can do it like this: - - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure - -Compiling For Multiple Architectures -==================================== - -You can compile readline for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - -If you have to use a `make' that does not supports the `VPATH' -variable, you have to compile readline for one architecture at a -time in the source code directory. After you have installed -readline for one architecture, use `make distclean' before -reconfiguring for another architecture. - -Installation Names -================== - -By default, `make install' will install the readline libraries in -`/usr/local/lib', the include files in -`/usr/local/include/readline', the man pages in `/usr/local/man', -and the info files in `/usr/local/info'. You can specify an -installation prefix other than `/usr/local' by giving `configure' -the option `--prefix=PATH' or by supplying a value for the -DESTDIR variable when running `make install'. - -You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. -If you give `configure' the option `--exec-prefix=PATH', the -readline Makefiles will use PATH as the prefix for installing the -libraries. Documentation and other data files will still use the -regular prefix. - -Specifying the System Type -========================== - -There may be some features `configure' can not figure out -automatically, but need to determine by the type of host readline -will run on. Usually `configure' can figure that out, but if it -prints a message saying it can not guess the host type, give it -the `--host=TYPE' option. TYPE can either be a short name for -the system type, such as `sun4', or a canonical name with three -fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). - -See the file `config.sub' for the possible values of each field. - -Sharing Defaults -================ - -If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: the readline `configure' looks for a site script, but not -all `configure' scripts do. - -Operation Controls -================== - -`configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--version' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`configure' also accepts some other, not widely useful, options. - -Optional Features -================= - -The readline `configure' recognizes a single `--with-PACKAGE' option: - -`--with-curses' - This tells readline that it can find the termcap library functions - (tgetent, et al.) in the curses library, rather than a separate - termcap library. Readline uses the termcap functions, but does not - link with the termcap or curses library itself, allowing applications - which link with readline the to choose an appropriate library. - This option tells readline to link the example programs with the - curses library rather than libtermcap. - -`configure' also recognizes two `--enable-FEATURE' options: - -`--enable-shared' - Build the shared libraries by default on supported platforms. The - default is `yes'. - -`--enable-static' - Build the static libraries by default. The default is `yes'. - -Shared Libraries -================ - -There is support for building shared versions of the readline and -history libraries. The configure script creates a Makefile in -the `shlib' subdirectory, and typing `make shared' will cause -shared versions of the readline and history libraries to be built -on supported platforms. - -If `configure' is given the `--enable-shared' option, it will attempt -to build the shared libraries by default on supported platforms. - -Configure calls the script support/shobj-conf to test whether or -not shared library creation is supported and to generate the values -of variables that are substituted into shlib/Makefile. If you -try to build shared libraries on an unsupported platform, `make' -will display a message asking you to update support/shobj-conf for -your platform. - -If you need to update support/shobj-conf, you will need to create -a `stanza' for your operating system and compiler. The script uses -the value of host_os and ${CC} as determined by configure. For -instance, FreeBSD 4.2 with any version of gcc is identified as -`freebsd4.2-gcc*'. - -In the stanza for your operating system-compiler pair, you will need to -define several variables. They are: - -SHOBJ_CC The C compiler used to compile source files into shareable - object files. This is normally set to the value of ${CC} - by configure, and should not need to be changed. - -SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create - position-independent code. If you are using gcc, this - should probably be set to `-fpic'. - -SHOBJ_LD The link editor to be used to create the shared library from - the object files created by $SHOBJ_CC. If you are using - gcc, a value of `gcc' will probably work. - -SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. - If you are using gcc, `-shared' may be all that is necessary. - These should be the flags needed for generic shared object - creation. - -SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library - creation. Many systems use the -R option to the link - editor to embed a path within the library for run-time - library searches. A reasonable value for such systems would - be `-R$(libdir)'. - -SHLIB_LIBS Any additional libraries that shared libraries should be - linked against when they are created. - -SHLIB_LIBPREF The prefix to use when generating the filename of the shared - library. The default is `lib'; Cygwin uses `cyg'. - -SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when - generating the filename of the shared library. Many systems - use `so'; HP-UX uses `sl'. - -SHLIB_LIBVERSION The string to append to the filename to indicate the version - of the shared library. It should begin with $(SHLIB_LIBSUFF), - and possibly include version information that allows the - run-time loader to load the version of the shared library - appropriate for a particular program. Systems using shared - libraries similar to SunOS 4.x use major and minor library - version numbers; for those systems a value of - `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. - Systems based on System V Release 4 don't use minor version - numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. - Other Unix versions use different schemes. - -SHLIB_DLLVERSION The version number for shared libraries that determines API - compatibility between readline versions and the underlying - system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but - can be overridden at configuration time by defining DLLVERSION - in the environment. - -SHLIB_DOT The character used to separate the name of the shared library - from the suffix and version information. The default is `.'; - systems like Cygwin which don't separate version information - from the library name should set this to the empty string. - -SHLIB_STATUS Set this to `supported' when you have defined the other - necessary variables. Make uses this to determine whether - or not shared library creation should be attempted. If - shared libraries are not supported, this will be set to - `unsupported'. - -You should look at the existing stanzas in support/shobj-conf for ideas. - -Once you have updated support/shobj-conf, re-run configure and type -`make shared' or `make'. The shared libraries will be created in the -shlib subdirectory. - -If shared libraries are created, `make install' will install them. -You may install only the shared libraries by running `make -install-shared' from the top-level build directory. Running `make -install' in the shlib subdirectory will also work. If you don't want -to install any created shared libraries, run `make install-static'. diff --git a/contrib/libreadline/MANIFEST b/contrib/libreadline/MANIFEST deleted file mode 100644 index b288fb6f80a1..000000000000 --- a/contrib/libreadline/MANIFEST +++ /dev/null @@ -1,146 +0,0 @@ -# -# Master distribution manifest for the standalone readline distribution -# -doc d -examples d -examples/rlfe d -support d -shlib d -COPYING f -README f -MANIFEST f -INSTALL f -CHANGELOG f -CHANGES f -NEWS f -USAGE f -aclocal.m4 f -config.h.in f -configure f -configure.in f -Makefile.in f -ansi_stdlib.h f -chardefs.h f -history.h f -histlib.h f -keymaps.h f -posixdir.h f -posixjmp.h f -posixstat.h f -readline.h f -rlconf.h f -rldefs.h f -rlmbutil.h f -rlprivate.h f -rlshell.h f -rlstdc.h f -rltty.h f -rltypedefs.h f -rlwinsize.h f -tcap.h f -tilde.h f -xmalloc.h f -bind.c f -callback.c f -compat.c f -complete.c f -display.c f -emacs_keymap.c f -funmap.c f -input.c f -isearch.c f -keymaps.c f -kill.c f -macro.c f -mbutil.c f -misc.c f -nls.c f -parens.c f -readline.c f -rltty.c f -savestring.c f -search.c f -shell.c f -signals.c f -terminal.c f -text.c f -tilde.c f -undo.c f -util.c f -vi_keymap.c f -vi_mode.c f -xmalloc.c f -history.c f -histexpand.c f -histfile.c f -histsearch.c f -shlib/Makefile.in f -support/config.guess f -support/config.rpath f -support/config.sub f -support/install.sh f -support/mkdirs f -support/mkdist f -support/mkinstalldirs f -support/shobj-conf f -support/shlib-install f -support/wcwidth.c f -doc/Makefile.in f -doc/texinfo.tex f -doc/version.texi f -doc/fdl.texi f -doc/rlman.texi f -doc/rltech.texi f -doc/rluser.texi f -doc/rluserman.texi f -doc/history.texi f -doc/hstech.texi f -doc/hsuser.texi f -doc/readline.3 f -doc/history.3 f -doc/texi2dvi f -doc/texi2html f -examples/Makefile.in f -examples/excallback.c f -examples/fileman.c f -examples/manexamp.c f -examples/readlinebuf.h f -examples/rl-fgets.c f -examples/rlcat.c f -examples/rltest.c f -examples/rl.c f -examples/rlptytest.c f -examples/rlversion.c f -examples/histexamp.c f -examples/Inputrc f -examples/rlfe/ChangeLog f -examples/rlfe/Makefile.in f -examples/rlfe/README f -examples/rlfe/config.h.in f -examples/rlfe/configure f -examples/rlfe/configure.in f -examples/rlfe/extern.h f -examples/rlfe/os.h f -examples/rlfe/pty.c f -examples/rlfe/rlfe.c f -examples/rlfe/screen.h f -# formatted documentation, from MANIFEST.doc -doc/readline.ps f -doc/history.ps f -doc/rluserman.ps f -doc/readline.dvi f -doc/history.dvi f -doc/rluserman.dvi f -doc/readline.info f -doc/history.info f -doc/rluserman.info f -doc/readline.html f -doc/history.html f -doc/rluserman.html f -doc/readline.0 f -doc/history.0 f -doc/readline_3.ps f -doc/history_3.ps f -doc/history.pdf f -doc/readline.pdf f -doc/rluserman.pdf f diff --git a/contrib/libreadline/Makefile.in b/contrib/libreadline/Makefile.in deleted file mode 100644 index 87df42831570..000000000000 --- a/contrib/libreadline/Makefile.in +++ /dev/null @@ -1,536 +0,0 @@ -## -*- text -*- ## -# Master Makefile for the GNU readline library. -# Copyright (C) 1994-2004 Free Software Foundation, Inc. - -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2, or (at your option) -# any later version. - -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Both -Emacs and vi editing modes are available. The Readline library includes -additional functions to maintain a list of previously-entered command -lines, to recall and perhaps reedit those lines, and perform csh-like -history expansion on previous commands. - -The history facilites are also placed into a separate library, the -History library, as part of the build process. The History library -may be used without Readline in applications which desire its -capabilities. - -The Readline library is free software, distributed under the terms of -the [GNU] General Public License, version 2. For more information, see -the file COPYING. - -To build the library, try typing `./configure', then `make'. The -configuration process is automated, so no further intervention should -be necessary. Readline builds with `gcc' by default if it is -available. If you want to use `cc' instead, type - - CC=cc ./configure - -if you are using a Bourne-style shell. If you are not, the following -may work: - - env CC=cc ./configure - -Read the file INSTALL in this directory for more information about how -to customize and control the build process. - -The file rlconf.h contains C preprocessor defines that enable and disable -certain Readline features. - -The special make target `everything' will build the static and shared -libraries (if the target platform supports them) and the examples. - -Examples -======== - -There are several example programs that use Readline features in the -examples directory. The `rl' program is of particular interest. It -is a command-line interface to Readline, suitable for use in shell -scripts in place of `read'. - -Shared Libraries -================ - -There is skeletal support for building shared versions of the -Readline and History libraries. The configure script creates -a Makefile in the `shlib' subdirectory, and typing `make shared' -will cause shared versions of the Readline and History libraries -to be built on supported platforms. - -If `configure' is given the `--enable-shared' option, it will attempt -to build the shared libraries by default on supported platforms. - -Configure calls the script support/shobj-conf to test whether or -not shared library creation is supported and to generate the values -of variables that are substituted into shlib/Makefile. If you -try to build shared libraries on an unsupported platform, `make' -will display a message asking you to update support/shobj-conf for -your platform. - -If you need to update support/shobj-conf, you will need to create -a `stanza' for your operating system and compiler. The script uses -the value of host_os and ${CC} as determined by configure. For -instance, FreeBSD 4.2 with any version of gcc is identified as -`freebsd4.2-gcc*'. - -In the stanza for your operating system-compiler pair, you will need to -define several variables. They are: - -SHOBJ_CC The C compiler used to compile source files into shareable - object files. This is normally set to the value of ${CC} - by configure, and should not need to be changed. - -SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create - position-independent code. If you are using gcc, this - should probably be set to `-fpic'. - -SHOBJ_LD The link editor to be used to create the shared library from - the object files created by $SHOBJ_CC. If you are using - gcc, a value of `gcc' will probably work. - -SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. - If you are using gcc, `-shared' may be all that is necessary. - These should be the flags needed for generic shared object - creation. - -SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library - creation. Many systems use the -R option to the link - editor to embed a path within the library for run-time - library searches. A reasonable value for such systems would - be `-R$(libdir)'. - -SHLIB_LIBS Any additional libraries that shared libraries should be - linked against when they are created. - -SHLIB_LIBPREF The prefix to use when generating the filename of the shared - library. The default is `lib'; Cygwin uses `cyg'. - -SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when - generating the filename of the shared library. Many systems - use `so'; HP-UX uses `sl'. - -SHLIB_LIBVERSION The string to append to the filename to indicate the version - of the shared library. It should begin with $(SHLIB_LIBSUFF), - and possibly include version information that allows the - run-time loader to load the version of the shared library - appropriate for a particular program. Systems using shared - libraries similar to SunOS 4.x use major and minor library - version numbers; for those systems a value of - `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. - Systems based on System V Release 4 don't use minor version - numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. - Other Unix versions use different schemes. - -SHLIB_DLLVERSION The version number for shared libraries that determines API - compatibility between readline versions and the underlying - system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but - can be overridden at configuration time by defining DLLVERSION - in the environment. - -SHLIB_DOT The character used to separate the name of the shared library - from the suffix and version information. The default is `.'; - systems like Cygwin which don't separate version information - from the library name should set this to the empty string. - -SHLIB_STATUS Set this to `supported' when you have defined the other - necessary variables. Make uses this to determine whether - or not shared library creation should be attempted. - -You should look at the existing stanzas in support/shobj-conf for ideas. - -Once you have updated support/shobj-conf, re-run configure and type -`make shared'. The shared libraries will be created in the shlib -subdirectory. - -If shared libraries are created, `make install' will install them. -You may install only the shared libraries by running `make -install-shared' from the top-level build directory. Running `make -install' in the shlib subdirectory will also work.

The -dnl default (if it is not specified or empty) is 'no-libtool'. -dnl INTLSYMBOL should be 'external' for packages with no intl directory, -dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. -dnl If INTLSYMBOL is 'use-libtool', then a libtool library -dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, -dnl depending on --{enable,disable}-{shared,static} and on the presence of -dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library -dnl $(top_builddir)/intl/libintl.a will be created. -dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext -dnl implementations (in libc or libintl) without the ngettext() function -dnl will be ignored. If NEEDSYMBOL is specified and is -dnl 'need-formatstring-macros', then GNU gettext implementations that don't -dnl support the ISO C 99 formatstring macros will be ignored. -dnl INTLDIR is used to find the intl libraries. If empty, -dnl the value `$(top_builddir)/intl/' is used. -dnl -dnl The result of the configuration is one of three cases: -dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled -dnl and used. -dnl Catalog format: GNU --> install in $(datadir) -dnl Catalog extension: .mo after installation, .gmo in source tree -dnl 2) GNU gettext has been found in the system's C library. -dnl Catalog format: GNU --> install in $(datadir) -dnl Catalog extension: .mo after installation, .gmo in source tree -dnl 3) No internationalization, always use English msgid. -dnl Catalog format: none -dnl Catalog extension: none -dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. -dnl The use of .gmo is historical (it was needed to avoid overwriting the -dnl GNU format catalogs when building on a platform with an X/Open gettext), -dnl but we keep it in order not to force irrelevant filename changes on the -dnl maintainers. -dnl -AC_DEFUN([AM_GNU_GETTEXT], -[ - dnl Argument checking. - ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , - [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT -])])])])]) - ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , - [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT -])])])]) - define(gt_included_intl, ifelse([$1], [external], [no], [yes])) - define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) - - AC_REQUIRE([AM_PO_SUBDIRS])dnl - ifelse(gt_included_intl, yes, [ - AC_REQUIRE([AM_INTL_SUBDIR])dnl - ]) - - dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. - AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) - AC_REQUIRE([AC_LIB_RPATH]) - - dnl Sometimes libintl requires libiconv, so first search for libiconv. - dnl Ideally we would do this search only after the - dnl if test "$USE_NLS" = "yes"; then - dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then - dnl tests.

Any member of the public is a -licensee, and is addressed as ``you''. You accept the license if you -copy, modify or distribute the work in a way requiring permission -under copyright law. - -A ``Modified Version'' of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A ``Secondary Section'' is a named appendix or a front-matter section -of the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall -subject (or to related matters) and contains nothing that could fall -directly within that overall subject. (Thus, if the Document is in -part a textbook of mathematics, a Secondary Section may not explain -any mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The ``Invariant Sections'' are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. If a -section does not fit the above definition of Secondary then it is not -allowed to be designated as Invariant. The Document may contain zero -Invariant Sections. If the Document does not identify any Invariant -Sections then there are none. - -The ``Cover Texts'' are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. A Front-Cover Text may -be at most 5 words, and a Back-Cover Text may be at most 25 words. - -A ``Transparent'' copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, that is suitable for revising the document -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup, or absence of markup, has been arranged to thwart -or discourage subsequent modification by readers is not Transparent. -An image format is not Transparent if used for any substantial amount -of text. A copy that is not ``Transparent'' is called ``Opaque''. - -Examples of suitable formats for Transparent copies include plain -@sc{ascii} without markup, Texinfo input format, La@TeX{} input -format, @acronym{SGML} or @acronym{XML} using a publicly available -@acronym{DTD}, and standard-conforming simple @acronym{HTML}, -PostScript or @acronym{PDF} designed for human modification.

The GNU -History library is able to keep track of those lines, associate arbitrary -data with each line, and utilize information from previous lines in -composing new ones. -.PP -.SH "HISTORY EXPANSION" -.PP -The history library supports a history expansion feature that -is identical to the history expansion in -.BR bash. -This section describes what syntax features are available. -.PP -History expansions introduce words from the history list into -the input stream, making it easy to repeat commands, insert the -arguments to a previous command into the current input line, or -fix errors in previous commands quickly. -.PP -History expansion is usually performed immediately after a complete line -is read. -It takes place in two parts. -The first is to determine which line from the history list -to use during substitution. -The second is to select portions of that line for inclusion into -the current one. -The line selected from the history is the \fIevent\fP, -and the portions of that line that are acted upon are \fIwords\fP. -Various \fImodifiers\fP are available to manipulate the selected words. -The line is broken into words in the same fashion as \fBbash\fP -does when reading input, -so that several words that would otherwise be separated -are considered one word when surrounded by quotes (see the -description of \fBhistory_tokenize()\fP below). -History expansions are introduced by the appearance of the -history expansion character, which is \^\fB!\fP\^ by default. -Only backslash (\^\fB\e\fP\^) and single quotes can quote -the history expansion character. -.SS Event Designators -.PP -An event designator is a reference to a command line entry in the -history list. -.PP -.PD 0 -.TP -.B ! -Start a history substitution, except when followed by a -.BR blank , -newline, = or (. -.TP -.B !\fIn\fR -Refer to command line -.IR n . -.TP -.B !\-\fIn\fR -Refer to the current command line minus -.IR n . -.TP -.B !! -Refer to the previous command. This is a synonym for `!\-1'. -.TP -.B !\fIstring\fR -Refer to the most recent command starting with -.IR string . -.TP -.B !?\fIstring\fR\fB[?]\fR -Refer to the most recent command containing -.IR string . -The trailing \fB?\fP may be omitted if -.I string -is followed immediately by a newline. -.TP -.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u -Quick substitution. Repeat the last command, replacing -.I string1 -with -.IR string2 . -Equivalent to -``!!:s/\fIstring1\fP/\fIstring2\fP/'' -(see \fBModifiers\fP below). -.TP -.B !# -The entire command line typed so far. -.PD -.SS Word Designators -.PP -Word designators are used to select desired words from the event. -A -.B : -separates the event specification from the word designator. -It may be omitted if the word designator begins with a -.BR ^ , -.BR $ , -.BR * , -.BR \- , -or -.BR % . -Words are numbered from the beginning of the line, -with the first word being denoted by 0 (zero). -Words are inserted into the current line separated by single spaces. -.PP -.PD 0 -.TP -.B 0 (zero) -The zeroth word. For the shell, this is the command -word. -.TP -.I n -The \fIn\fRth word. -.TP -.B ^ -The first argument. That is, word 1. -.TP -.B $ -The last argument. -.TP -.B % -The word matched by the most recent `?\fIstring\fR?' search. -.TP -.I x\fB\-\fPy -A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'. -.TP -.B * -All of the words but the zeroth. This is a synonym -for `\fI1\-$\fP'. It is not an error to use -.B * -if there is just one -word in the event; the empty string is returned in that case. -.TP -.B x* -Abbreviates \fIx\-$\fP. -.TP -.B x\- -Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word. -.PD -.PP -If a word designator is supplied without an event specification, the -previous command is used as the event. -.SS Modifiers -.PP -After the optional word designator, there may appear a sequence of -one or more of the following modifiers, each preceded by a `:'. -.PP -.PD 0 -.PP -.TP -.B h -Remove a trailing file name component, leaving only the head. -.TP -.B t -Remove all leading file name components, leaving the tail. -.TP -.B r -Remove a trailing suffix of the form \fI.xxx\fP, leaving the -basename. -.TP -.B e -Remove all but the trailing suffix. -.TP -.B p -Print the new command but do not execute it. -.TP -.B q -Quote the substituted words, escaping further substitutions. -.TP -.B x -Quote the substituted words as with -.BR q , -but break into words at -.B blanks -and newlines. -.TP -.B s/\fIold\fP/\fInew\fP/ -Substitute -.I new -for the first occurrence of -.I old -in the event line. Any delimiter can be used in place of /. The -final delimiter is optional if it is the last character of the -event line. The delimiter may be quoted in -.I old -and -.I new -with a single backslash. If & appears in -.IR new , -it is replaced by -.IR old . -A single backslash will quote the &. If -.I old -is null, it is set to the last -.I old -substituted, or, if no previous history substitutions took place, -the last -.I string -in a -.B !?\fIstring\fR\fB[?]\fR -search. -.TP -.B & -Repeat the previous substitution. -.TP -.B g -Cause changes to be applied over the entire event line. This is -used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR') -or `\fB:&\fP'. If used with -`\fB:s\fP', any delimiter can be used -in place of /, and the final delimiter is optional -if it is the last character of the event line. -An \fBa\fP may be used as a synonym for \fBg\fP. -.TP -.B G -Apply the following `\fBs\fP' modifier once to each word in the event line. -.PD -.SH "PROGRAMMING WITH HISTORY FUNCTIONS" -This section describes how to use the History library in other programs. -.SS Introduction to History -.PP -The programmer using the History library has available functions -for remembering lines on a history list, associating arbitrary data -with a line, removing lines from the list, searching through the list -for a line containing an arbitrary text string, and referencing any line -in the list directly. In addition, a history \fIexpansion\fP function -is available which provides for a consistent user interface across -different programs. -.PP -The user using programs written with the History library has the -benefit of a consistent user interface with a set of well-known -commands for manipulating the text of previous lines and using that text -in new commands. The basic history manipulation commands are -identical to -the history substitution provided by \fBbash\fP. -.PP -If the programmer desires, he can use the Readline library, which -includes some history manipulation by default, and has the added -advantage of command line editing. -.PP -Before declaring any functions using any functionality the History -library provides in other code, an application writer should include -the file -.FN -in any file that uses the -History library's features. It supplies extern declarations for all -of the library's public functions and variables, and declares all of -the public data structures. - -.SS History Storage -.PP -The history list is an array of history entries.

If -.B prompt -is \fBNULL\fP or the empty string, no prompt is issued. -The line returned is allocated with -.IR malloc (3); -the caller must free it when finished. The line returned -has the final newline removed, so only the text of the line -remains. -.LP -.B readline -offers editing capabilities while the user is entering the -line. -By default, the line editing commands -are similar to those of emacs. -A vi\-style line editing interface is also available. -.LP -This manual page describes only the most basic use of \fBreadline\fP. -Much more functionality is available; see -\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP -for additional information. -.SH RETURN VALUE -.LP -.B readline -returns the text of the line read. A blank line -returns the empty string. If -.B EOF -is encountered while reading a line, and the line is empty, -.B NULL -is returned. If an -.B EOF -is read with a non\-empty line, it is -treated as a newline. -.SH NOTATION -.LP -An emacs-style notation is used to denote -keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n -means Control\-N. Similarly, -.I meta -keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards -without a -.I meta -key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key -then the -.I x -key. This makes ESC the \fImeta prefix\fP. -The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, -or press the Escape key -then hold the Control key while pressing the -.I x -key.) -.PP -Readline commands may be given numeric -.IR arguments , -which normally act as a repeat count. Sometimes, however, it is the -sign of the argument that is significant. Passing a negative argument -to a command that acts in the forward direction (e.g., \fBkill\-line\fP) -causes that command to act in a backward direction. Commands whose -behavior with arguments deviates from this are noted. -.PP -When a command is described as \fIkilling\fP text, the text -deleted is saved for possible future retrieval -(\fIyanking\fP). The killed text is saved in a -\fIkill ring\fP. Consecutive kills cause the text to be -accumulated into one unit, which can be yanked all at once. -Commands which do not kill text separate the chunks of text -on the kill ring. -.SH INITIALIZATION FILE -.LP -Readline is customized by putting commands in an initialization -file (the \fIinputrc\fP file). -The name of this file is taken from the value of the -.B INPUTRC -environment variable. If that variable is unset, the default is -.IR ~/.inputrc . -If that file does not exist or cannot be read, the ultimate default is -.IR /etc/inputrc . -When a program which uses the readline library starts up, the -init file is read, and the key bindings and variables are set. -There are only a few basic constructs allowed in the -readline init file. Blank lines are ignored. -Lines beginning with a \fB#\fP are comments. -Lines beginning with a \fB$\fP indicate conditional constructs. -Other lines denote key bindings and variable settings. -Each program using this library may add its own commands -and bindings. -.PP -For example, placing -.RS -.PP -M\-Control\-u: universal\-argument -.RE -or -.RS -C\-Meta\-u: universal\-argument -.RE -.sp -into the -.I inputrc -would make M\-C\-u execute the readline command -.IR universal\-argument . -.PP -The following symbolic character names are recognized while -processing key bindings: -.IR DEL , -.IR ESC , -.IR ESCAPE , -.IR LFD , -.IR NEWLINE , -.IR RET , -.IR RETURN , -.IR RUBOUT , -.IR SPACE , -.IR SPC , -and -.IR TAB . -.PP -In addition to command names, readline allows keys to be bound -to a string that is inserted when the key is pressed (a \fImacro\fP). -.PP -.SS Key Bindings -.PP -The syntax for controlling key bindings in the -.I inputrc -file is simple. All that is required is the name of the -command or the text of a macro and a key sequence to which -it should be bound. The name may be specified in one of two ways: -as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP -prefixes, or as a key sequence. -The name and key sequence are separated by a colon. There can be no -whitespace between the name and the colon. -.PP -When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP, -.I keyname -is the name of a key spelled out in English. For example: -.sp -.RS -Control\-u: universal\-argument -.br -Meta\-Rubout: backward\-kill\-word -.br -Control\-o: "> output" -.RE -.LP -In the above example, -.I C\-u -is bound to the function -.BR universal\-argument , -.I M-DEL -is bound to the function -.BR backward\-kill\-word , -and -.I C\-o -is bound to run the macro -expressed on the right hand side (that is, to insert the text -.if t \f(CW> output\fP -.if n ``> output'' -into the line). -.PP -In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, -.B keyseq -differs from -.B keyname -above in that strings denoting -an entire key sequence may be specified by placing the sequence -within double quotes.

The -.I inputrc -file may be edited and re-read if a program does not provide -any other means to incorporate new bindings. -.SS Variables -.PP -Readline has variables that can be used to further customize its -behavior. A variable may be set in the -.I inputrc -file with a statement of the form -.RS -.PP -\fBset\fP \fIvariable\-name\fP \fIvalue\fP -.RE -.PP -Except where noted, readline variables can take the values -.B On -or -.B Off -(without regard to case). -Unrecognized variable names are ignored. -When a variable value is read, empty or null values, "on" (case-insensitive), -and "1" are equivalent to \fBOn\fP. All other values are equivalent to -\fBOff\fP. -The variables and their default values are: -.PP -.PD 0 -.TP -.B bell\-style (audible) -Controls what happens when readline wants to ring the terminal bell. -If set to \fBnone\fP, readline never rings the bell. If set to -\fBvisible\fP, readline uses a visible bell if one is available. -If set to \fBaudible\fP, readline attempts to ring the terminal's bell. -.TP -.B bind\-tty\-special\-chars (On) -If set to \fBOn\fP, readline attempts to bind the control characters -treated specially by the kernel's terminal driver to their readline -equivalents. -.TP -.B comment\-begin (``#'') -The string that is inserted in \fBvi\fP mode when the -.B insert\-comment -command is executed. -This command is bound to -.B M\-# -in emacs mode and to -.B # -in vi command mode. -.TP -.B completion\-ignore\-case (Off) -If set to \fBOn\fP, readline performs filename matching and completion -in a case\-insensitive fashion. -.TP -.B completion\-query\-items (100) -This determines when the user is queried about viewing -the number of possible completions -generated by the \fBpossible\-completions\fP command. -It may be set to any integer value greater than or equal to -zero. If the number of possible completions is greater than -or equal to the value of this variable, the user is asked whether -or not he wishes to view them; otherwise they are simply listed -on the terminal. A negative value causes readline to never ask. -.TP -.B convert\-meta (On) -If set to \fBOn\fP, readline will convert characters with the -eighth bit set to an ASCII key sequence -by stripping the eighth bit and prefixing it with an -escape character (in effect, using escape as the \fImeta prefix\fP). -.TP -.B disable\-completion (Off) -If set to \fBOn\fP, readline will inhibit word completion. Completion -characters will be inserted into the line as if they had been -mapped to \fBself-insert\fP. -.TP -.B editing\-mode (emacs) -Controls whether readline begins with a set of key bindings similar -to emacs or vi. -.B editing\-mode -can be set to either -.B emacs -or -.BR vi . -.TP -.B enable\-keypad (Off) -When set to \fBOn\fP, readline will try to enable the application -keypad when it is called. Some systems need this to enable the -arrow keys. -.TP -.B expand\-tilde (Off) -If set to \fBon\fP, tilde expansion is performed when readline -attempts word completion. -.TP -.B history\-preserve\-point (Off) -If set to \fBon\fP, the history code attempts to place point at the -same location on each history line retrieved with \fBprevious-history\fP -or \fBnext-history\fP. -.TP -.B horizontal\-scroll\-mode (Off) -When set to \fBOn\fP, makes readline use a single line for display, -scrolling the input horizontally on a single screen line when it -becomes longer than the screen width rather than wrapping to a new line. -.TP -.B input\-meta (Off) -If set to \fBOn\fP, readline will enable eight-bit input (that is, -it will not clear the eighth bit in the characters it reads), -regardless of what the terminal claims it can support. The name -.B meta\-flag -is a synonym for this variable. -.TP -.B isearch\-terminators (``C\-[ C\-J'') -The string of characters that should terminate an incremental -search without subsequently executing the character as a command. -If this variable has not been given a value, the characters -\fIESC\fP and \fIC\-J\fP will terminate an incremental search. -.TP -.B keymap (emacs) -Set the current readline keymap. The set of legal keymap names is -\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, -vi-command\fP, and -.IR vi-insert . -\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is -equivalent to \fIemacs-standard\fP. The default value is -.IR emacs . -The value of -.B editing\-mode -also affects the default keymap. -.TP -.B mark\-directories (On) -If set to \fBOn\fP, completed directory names have a slash -appended. -.TP -.B mark\-modified\-lines (Off) -If set to \fBOn\fP, history lines that have been modified are displayed -with a preceding asterisk (\fB*\fP). -.TP -.B mark\-symlinked\-directories (Off) -If set to \fBOn\fP, completed names which are symbolic links to directories -have a slash appended (subject to the value of -\fBmark\-directories\fP). -.TP -.B match\-hidden\-files (On) -This variable, when set to \fBOn\fP, causes readline to match files whose -names begin with a `.' (hidden files) when performing filename -completion, unless the leading `.' is -supplied by the user in the filename to be completed. -.TP -.B output\-meta (Off) -If set to \fBOn\fP, readline will display characters with the -eighth bit set directly rather than as a meta-prefixed escape -sequence. -.TP -.B page\-completions (On) -If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager -to display a screenful of possible completions at a time. -.TP -.B print\-completions\-horizontally (Off) -If set to \fBOn\fP, readline will display completions with matches -sorted horizontally in alphabetical order, rather than down the screen. -.TP -.B show\-all\-if\-ambiguous (Off) -This alters the default behavior of the completion functions. If -set to -.BR on , -words which have more than one possible completion cause the -matches to be listed immediately instead of ringing the bell. -.TP -.B show\-all\-if\-unmodified (Off) -This alters the default behavior of the completion functions in -a fashion similar to \fBshow\-all\-if\-ambiguous\fP. -If set to -.BR on , -words which have more than one possible completion without any -possible partial completion (the possible completions don't share -a common prefix) cause the matches to be listed immediately instead -of ringing the bell. -.TP -.B visible\-stats (Off) -If set to \fBOn\fP, a character denoting a file's type as reported -by \fIstat\fP(2) is appended to the filename when listing possible -completions. -.PD -.SS Conditional Constructs -.PP -Readline implements a facility similar in spirit to the conditional -compilation features of the C preprocessor which allows key -bindings and variable settings to be performed as the result -of tests. There are four parser directives used. -.IP \fB$if\fP -The -.B $if -construct allows bindings to be made based on the -editing mode, the terminal being used, or the application using -readline. The text of the test extends to the end of the line; -no characters are required to isolate it. -.RS -.IP \fBmode\fP -The \fBmode=\fP form of the \fB$if\fP directive is used to test -whether readline is in emacs or vi mode. -This may be used in conjunction -with the \fBset keymap\fP command, for instance, to set bindings in -the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if -readline is starting out in emacs mode. -.IP \fBterm\fP -The \fBterm=\fP form may be used to include terminal-specific -key bindings, perhaps to bind the key sequences output by the -terminal's function keys. The word on the right side of the -.B = -is tested against the full name of the terminal and the portion -of the terminal name before the first \fB\-\fP. This allows -.I sun -to match both -.I sun -and -.IR sun\-cmd , -for instance. -.IP \fBapplication\fP -The \fBapplication\fP construct is used to include -application-specific settings. Each program using the readline -library sets the \fIapplication name\fP, and an initialization -file can test for a particular value. -This could be used to bind key sequences to functions useful for -a specific program. For instance, the following command adds a -key sequence that quotes the current or previous word in Bash: -.sp 1 -.RS -.nf -\fB$if\fP Bash -# Quote the current or previous word -"\eC-xq": "\eeb\e"\eef\e"" -\fB$endif\fP -.fi -.RE -.RE -.IP \fB$endif\fP -This command, as seen in the previous example, terminates an -\fB$if\fP command. -.IP \fB$else\fP -Commands in this branch of the \fB$if\fP directive are executed if -the test fails. -.IP \fB$include\fP -This directive takes a single filename as an argument and reads commands -and bindings from that file. For example, the following directive -would read \fI/etc/inputrc\fP: -.sp 1 -.RS -.nf -\fB$include\fP \^ \fI/etc/inputrc\fP -.fi -.RE -.SH SEARCHING -.PP -Readline provides commands for searching through the command history -for lines containing a specified string. -There are two search modes: -.I incremental -and -.IR non-incremental . -.PP -Incremental searches begin before the user has finished typing the -search string. -As each character of the search string is typed, readline displays -the next entry from the history matching the string typed so far. -An incremental search requires only as many characters as needed to -find the desired history entry. -To search backward in the history for a particular string, type -\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history. -The characters present in the value of the \fBisearch-terminators\fP -variable are used to terminate an incremental search. -If that variable has not been assigned a value the \fIEscape\fP and -\fBC\-J\fP characters will terminate an incremental search. -\fBC\-G\fP will abort an incremental search and restore the original -line. -When the search is terminated, the history entry containing the -search string becomes the current line. -.PP -To find other matching entries in the history list, type \fBC\-s\fP or -\fBC\-r\fP as appropriate. -This will search backward or forward in the history for the next -line matching the search string typed so far. -Any other key sequence bound to a readline command will terminate -the search and execute that command. -For instance, a newline will terminate the search and accept -the line, thereby executing the command from the history list. -A movement command will terminate the search, make the last line found -the current line, and begin editing. -.PP -Non-incremental searches read the entire search string before starting -to search for matching history lines. The search string may be -typed by the user or be part of the contents of the current line. -.SH EDITING COMMANDS -.PP -The following is a list of the names of the commands and the default -key sequences to which they are bound. -Command names without an accompanying key sequence are unbound by default. -.PP -In the following descriptions, \fIpoint\fP refers to the current cursor -position, and \fImark\fP refers to a cursor position saved by the -\fBset\-mark\fP command. -The text between the point and mark is referred to as the \fIregion\fP. -.SS Commands for Moving -.PP -.PD 0 -.TP -.B beginning\-of\-line (C\-a) -Move to the start of the current line. -.TP -.B end\-of\-line (C\-e) -Move to the end of the line. -.TP -.B forward\-char (C\-f) -Move forward a character. -.TP -.B backward\-char (C\-b) -Move back a character. -.TP -.B forward\-word (M\-f) -Move forward to the end of the next word. Words are composed of -alphanumeric characters (letters and digits). -.TP -.B backward\-word (M\-b) -Move back to the start of the current or previous word. Words are -composed of alphanumeric characters (letters and digits). -.TP -.B clear\-screen (C\-l) -Clear the screen leaving the current line at the top of the screen. -With an argument, refresh the current line without clearing the -screen. -.TP -.B redraw\-current\-line -Refresh the current line. -.PD -.SS Commands for Manipulating the History -.PP -.PD 0 -.TP -.B accept\-line (Newline, Return) -Accept the line regardless of where the cursor is. -If this line is -non-empty, it may be added to the history list for future recall with -\fBadd_history()\fP. -If the line is a modified history line, the history line is restored to its original state. -.TP -.B previous\-history (C\-p) -Fetch the previous command from the history list, moving back in -the list. -.TP -.B next\-history (C\-n) -Fetch the next command from the history list, moving forward in the -list. -.TP -.B beginning\-of\-history (M\-<) -Move to the first line in the history. -.TP -.B end\-of\-history (M\->) -Move to the end of the input history, i.e., the line currently being -entered. -.TP -.B reverse\-search\-history (C\-r) -Search backward starting at the current line and moving `up' through -the history as necessary. This is an incremental search. -.TP -.B forward\-search\-history (C\-s) -Search forward starting at the current line and moving `down' through -the history as necessary. This is an incremental search. -.TP -.B non\-incremental\-reverse\-search\-history (M\-p) -Search backward through the history starting at the current line -using a non-incremental search for a string supplied by the user. -.TP -.B non\-incremental\-forward\-search\-history (M\-n) -Search forward through the history using a non-incremental search -for a string supplied by the user. -.TP -.B history\-search\-forward -Search forward through the history for the string of characters -between the start of the current line and the current cursor -position (the \fIpoint\fP). -This is a non-incremental search. -.TP -.B history\-search\-backward -Search backward through the history for the string of characters -between the start of the current line and the point. -This is a non-incremental search. -.TP -.B yank\-nth\-arg (M\-C\-y) -Insert the first argument to the previous command (usually -the second word on the previous line) at point. -With an argument -.IR n , -insert the \fIn\fPth word from the previous command (the words -in the previous command begin with word 0). A negative argument -inserts the \fIn\fPth word from the end of the previous command. -Once the argument \fIn\fP is computed, the argument is extracted -as if the "!\fIn\fP" history expansion had been specified. -.TP -.B -yank\-last\-arg (M\-.\^, M\-_\^) -Insert the last argument to the previous command (the last word of -the previous history entry). With an argument, -behave exactly like \fByank\-nth\-arg\fP. -Successive calls to \fByank\-last\-arg\fP move back through the history -list, inserting the last argument of each line in turn. -The history expansion facilities are used to extract the last argument, -as if the "!$" history expansion had been specified. -.PD -.SS Commands for Changing Text -.PP -.PD 0 -.TP -.B delete\-char (C\-d) -Delete the character at point. If point is at the -beginning of the line, there are no characters in the line, and -the last character typed was not bound to \fBdelete\-char\fP, then return -.SM -.BR EOF . -.TP -.B backward\-delete\-char (Rubout) -Delete the character behind the cursor. When given a numeric argument, -save the deleted text on the kill ring. -.TP -.B forward\-backward\-delete\-char -Delete the character under the cursor, unless the cursor is at the -end of the line, in which case the character behind the cursor is -deleted. -.TP -.B quoted\-insert (C\-q, C\-v) -Add the next character that you type to the line verbatim. This is -how to insert characters like \fBC\-q\fP, for example. -.TP -.B tab\-insert (M-TAB) -Insert a tab character. -.TP -.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...) -Insert the character typed. -.TP -.B transpose\-chars (C\-t) -Drag the character before point forward over the character at point, -moving point forward as well. -If point is at the end of the line, then this transposes -the two characters before point. -Negative arguments have no effect. -.TP -.B transpose\-words (M\-t) -Drag the word before point past the word after point, -moving point over that word as well. -If point is at the end of the line, this transposes -the last two words on the line. -.TP -.B upcase\-word (M\-u) -Uppercase the current (or following) word. With a negative argument, -uppercase the previous word, but do not move point. -.TP -.B downcase\-word (M\-l) -Lowercase the current (or following) word. With a negative argument, -lowercase the previous word, but do not move point. -.TP -.B capitalize\-word (M\-c) -Capitalize the current (or following) word. With a negative argument, -capitalize the previous word, but do not move point. -.TP -.B overwrite\-mode -Toggle overwrite mode. With an explicit positive numeric argument, -switches to overwrite mode. With an explicit non-positive numeric -argument, switches to insert mode. This command affects only -\fBemacs\fP mode; \fBvi\fP mode does overwrite differently. -Each call to \fIreadline()\fP starts in insert mode. -In overwrite mode, characters bound to \fBself\-insert\fP replace -the text at point rather than pushing the text to the right. -Characters bound to \fBbackward\-delete\-char\fP replace the character -before point with a space.

Word boundaries are the same as -those used by \fBforward\-word\fP. -.TP -.B backward\-kill\-word (M\-Rubout) -Kill the word behind point. -Word boundaries are the same as those used by \fBbackward\-word\fP. -.TP -.B unix\-word\-rubout (C\-w) -Kill the word behind point, using white space as a word boundary. -The killed text is saved on the kill-ring. -.TP -.B unix\-filename\-rubout -Kill the word behind point, using white space and the slash character -as the word boundaries. -The killed text is saved on the kill-ring. -.TP -.B delete\-horizontal\-space (M\-\e) -Delete all spaces and tabs around point. -.TP -.B kill\-region -Kill the text between the point and \fImark\fP (saved cursor position). -This text is referred to as the \fIregion\fP. -.TP -.B copy\-region\-as\-kill -Copy the text in the region to the kill buffer. -.TP -.B copy\-backward\-word -Copy the word before point to the kill buffer. -The word boundaries are the same as \fBbackward\-word\fP. -.TP -.B copy\-forward\-word -Copy the word following point to the kill buffer. -The word boundaries are the same as \fBforward\-word\fP. -.TP -.B yank (C\-y) -Yank the top of the kill ring into the buffer at point. -.TP -.B yank\-pop (M\-y) -Rotate the kill ring, and yank the new top. Only works following -.B yank -or -.BR yank\-pop . -.PD -.SS Numeric Arguments -.PP -.PD 0 -.TP -.B digit\-argument (M\-0, M\-1, ..., M\-\-) -Add this digit to the argument already accumulating, or start a new -argument. M\-\- starts a negative argument. -.TP -.B universal\-argument -This is another way to specify an argument. -If this command is followed by one or more digits, optionally with a -leading minus sign, those digits define the argument. -If the command is followed by digits, executing -.B universal\-argument -again ends the numeric argument, but is otherwise ignored. -As a special case, if this command is immediately followed by a -character that is neither a digit or minus sign, the argument count -for the next command is multiplied by four. -The argument count is initially one, so executing this function the -first time makes the argument count four, a second time makes the -argument count sixteen, and so on. -.PD -.SS Completing -.PP -.PD 0 -.TP -.B complete (TAB) -Attempt to perform completion on the text before point. -The actual completion performed is application-specific. -.BR Bash , -for instance, attempts completion treating the text as a variable -(if the text begins with \fB$\fP), username (if the text begins with -\fB~\fP), hostname (if the text begins with \fB@\fP), or -command (including aliases and functions) in turn. If none -of these produces a match, filename completion is attempted. -.BR Gdb , -on the other hand, -allows completion of program functions and variables, and -only attempts filename completion under certain circumstances. -.TP -.B possible\-completions (M\-?) -List the possible completions of the text before point. -.TP -.B insert\-completions (M\-*) -Insert all completions of the text before point -that would have been generated by -\fBpossible\-completions\fP. -.TP -.B menu\-complete -Similar to \fBcomplete\fP, but replaces the word to be completed -with a single match from the list of possible completions. -Repeated execution of \fBmenu\-complete\fP steps through the list -of possible completions, inserting each match in turn. -At the end of the list of completions, the bell is rung -(subject to the setting of \fBbell\-style\fP) -and the original text is restored. -An argument of \fIn\fP moves \fIn\fP positions forward in the list -of matches; a negative argument may be used to move backward -through the list. -This command is intended to be bound to \fBTAB\fP, but is unbound -by default. -.TP -.B delete\-char\-or\-list -Deletes the character under the cursor if not at the beginning or -end of the line (like \fBdelete-char\fP). -If at the end of the line, behaves identically to -\fBpossible-completions\fP. -.PD -.SS Keyboard Macros -.PP -.PD 0 -.TP -.B start\-kbd\-macro (C\-x (\^) -Begin saving the characters typed into the current keyboard macro. -.TP -.B end\-kbd\-macro (C\-x )\^) -Stop saving the characters typed into the current keyboard macro -and store the definition. -.TP -.B call\-last\-kbd\-macro (C\-x e) -Re-execute the last keyboard macro defined, by making the characters -in the macro appear as if typed at the keyboard. -.PD -.SS Miscellaneous -.PP -.PD 0 -.TP -.B re\-read\-init\-file (C\-x C\-r) -Read in the contents of the \fIinputrc\fP file, and incorporate -any bindings or variable assignments found there. -.TP -.B abort (C\-g) -Abort the current editing command and -ring the terminal's bell (subject to the setting of -.BR bell\-style ). -.TP -.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...) -If the metafied character \fIx\fP is lowercase, run the command -that is bound to the corresponding uppercase character. -.TP -.B prefix\-meta (ESC) -Metafy the next character typed. -.SM -.B ESC -.B f -is equivalent to -.BR Meta\-f . -.TP -.B undo (C\-_, C\-x C\-u) -Incremental undo, separately remembered for each line. -.TP -.B revert\-line (M\-r) -Undo all changes made to this line.

A negative count searches for previous occurrences. -.TP -.B character\-search\-backward (M\-C\-]) -A character is read and point is moved to the previous occurrence of that -character. A negative count searches for subsequent occurrences. -.TP -.B insert\-comment (M\-#) -Without a numeric argument, the value of the readline -.B comment\-begin -variable is inserted at the beginning of the current line. -If a numeric argument is supplied, this command acts as a toggle: if -the characters at the beginning of the line do not match the value -of \fBcomment\-begin\fP, the value is inserted, otherwise -the characters in \fBcomment-begin\fP are deleted from the beginning of -the line. -In either case, the line is accepted as if a newline had been typed. -The default value of -.B comment\-begin -makes the current line a shell comment. -If a numeric argument causes the comment character to be removed, the line -will be executed by the shell. -.TP -.B dump\-functions -Print all of the functions and their key bindings to the -readline output stream. If a numeric argument is supplied, -the output is formatted in such a way that it can be made part -of an \fIinputrc\fP file. -.TP -.B dump\-variables -Print all of the settable variables and their values to the -readline output stream.

This section describes how to use Readline in -the simplest way possible, perhaps to replace calls in your code to -@code{gets()} or @code{fgets()}. - -@findex readline -@cindex readline, function - -The function @code{readline()} prints a prompt @var{prompt} -and then reads and returns a single line of text from the user. -If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed. -The line @code{readline} returns is allocated with @code{malloc()}; -the caller should @code{free()} the line when it has finished with it. -The declaration for @code{readline} in ANSI C is - -@example -@code{char *readline (const char *@var{prompt});} -@end example - -@noindent -So, one might say -@example -@code{char *line = readline ("Enter a line: ");} -@end example -@noindent -in order to read a line of text from the user. -The line returned has the final newline removed, so only the -text remains. - -If @code{readline} encounters an @code{EOF} while reading the line, and the -line is empty at that point, then @code{(char *)NULL} is returned. -Otherwise, the line is ended just as if a newline had been typed. - -If you want the user to be able to get at the line later, (with -@key{C-p} for example), you must call @code{add_history()} to save the -line away in a @dfn{history} list of such lines. - -@example -@code{add_history (line)}; -@end example - -@noindent -For full details on the GNU History Library, see the associated manual. - -It is preferable to avoid saving empty lines on the history list, since -users rarely have a burning need to reuse a blank line. Here is -a function which usefully replaces the standard @code{gets()} library -function, and has the advantage of no static buffer to overflow: - -@example -/* A static variable for holding the line. */ -static char *line_read = (char *)NULL; - -/* Read a string, and return a pointer to it. - Returns NULL on EOF. */ -char * -rl_gets () -@{ - /* If the buffer has already been allocated, - return the memory to the free pool. */ - if (line_read) - @{ - free (line_read); - line_read = (char *)NULL; - @} - - /* Get a line from the user. */ - line_read = readline (""); - - /* If the line has any text in it, - save it on the history. */ - if (line_read && *line_read) - add_history (line_read); - - return (line_read); -@} -@end example - -This function gives the user the default behaviour of @key{TAB} -completion: completion on file names. If you do not want Readline to -complete on filenames, you can change the binding of the @key{TAB} key -with @code{rl_bind_key()}. - -@example -@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});} -@end example - -@code{rl_bind_key()} takes two arguments: @var{key} is the character that -you want to bind, and @var{function} is the address of the function to -call when @var{key} is pressed. Binding @key{TAB} to @code{rl_insert()} -makes @key{TAB} insert itself. -@code{rl_bind_key()} returns non-zero if @var{key} is not a valid -ASCII character code (between 0 and 255). - -Thus, to disable the default @key{TAB} behavior, the following suffices: -@example -@code{rl_bind_key ('\t', rl_insert);} -@end example - -This code should be executed once at the start of your program; you -might write a function called @code{initialize_readline()} which -performs this and other desired initializations, such as installing -custom completers (@pxref{Custom Completers}). - -@node Custom Functions -@section Custom Functions - -Readline provides many functions for manipulating the text of -the line, but it isn't possible to anticipate the needs of all -programs. This section describes the various functions and variables -defined within the Readline library which allow a user program to add -customized functionality to Readline. - -Before declaring any functions that customize Readline's behavior, or -using any functionality Readline provides in other code, an -application writer should include the file @code{} -in any file that uses Readline's features. Since some of the definitions -in @code{readline.h} use the @code{stdio} library, the file -@code{} should be included before @code{readline.h}. - -@code{readline.h} defines a C preprocessor variable that should -be treated as an integer, @code{RL_READLINE_VERSION}, which may -be used to conditionally compile application code depending on -the installed Readline version.

They are intended to indicate -exceptional events, like a user pressing the interrupt key on his terminal, -or a network connection being broken. There is a class of signals that can -be sent to the process currently reading input from the keyboard. Since -Readline changes the terminal attributes when it is called, it needs to -perform special processing when such a signal is received in order to -restore the terminal to a sane state, or provide application writers with -functions to do so manually. - -Readline contains an internal signal handler that is installed for a -number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, -@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}). -When one of these signals is received, the signal handler -will reset the terminal attributes to those that were in effect before -@code{readline()} was called, reset the signal handling to what it was -before @code{readline()} was called, and resend the signal to the calling -application. -If and when the calling application's signal handler returns, Readline -will reinitialize the terminal and continue to accept input. -When a @code{SIGINT} is received, the Readline signal handler performs -some additional work, which will cause any partially-entered line to be -aborted (see the description of @code{rl_free_line_state()} below). - -There is an additional Readline signal handler, for @code{SIGWINCH}, which -the kernel sends to a process whenever the terminal's size changes (for -example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH} -handler updates Readline's internal screen size information, and then calls -any @code{SIGWINCH} signal handler the calling application has installed. -Readline calls the application's @code{SIGWINCH} signal handler without -resetting the terminal to its original state. If the application's signal -handler does more than update its idea of the terminal size and return (for -example, a @code{longjmp} back to a main processing loop), it @emph{must} -call @code{rl_cleanup_after_signal()} (described below), to restore the -terminal state. - -Readline provides two variables that allow application writers to -control whether or not it will catch certain signals and act on them -when they are received. It is important that applications change the -values of these variables only when calling @code{readline()}, not in -a signal handler, so Readline's internal signal state is not corrupted. - -@deftypevar int rl_catch_signals -If this variable is non-zero, Readline will install signal handlers for -@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM}, -@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}. - -The default value of @code{rl_catch_signals} is 1. -@end deftypevar - -@deftypevar int rl_catch_sigwinch -If this variable is non-zero, Readline will install a signal handler for -@code{SIGWINCH}. - -The default value of @code{rl_catch_sigwinch} is 1. -@end deftypevar - -If an application does not wish to have Readline catch any signals, or -to handle signals other than those Readline catches (@code{SIGHUP}, -for example), -Readline provides convenience functions to do the necessary terminal -and internal state cleanup upon receipt of a signal. - -@deftypefun void rl_cleanup_after_signal (void) -This function will reset the state of the terminal to what it was before -@code{readline()} was called, and remove the Readline signal handlers for -all signals, depending on the values of @code{rl_catch_signals} and -@code{rl_catch_sigwinch}. -@end deftypefun - -@deftypefun void rl_free_line_state (void) -This will free any partial state associated with the current input line -(undo information, any partial history entry, any partially-entered -keyboard macro, and any partially-entered numeric argument).

That is, it is not possible to accurately -expand a partial word without knowing all of the possible words -which make sense in that context. The Readline library provides -the user interface to completion, and two of the most common -completion functions: filename and username. For completing other types -of text, you must write your own completion function. This section -describes exactly what such functions must do, and provides an example. - -There are three major functions used to perform completion: - -@enumerate -@item -The user-interface function @code{rl_complete()}. This function is -called with the same arguments as other bindable Readline functions: -@var{count} and @var{invoking_key}. -It isolates the word to be completed and calls -@code{rl_completion_matches()} to generate a list of possible completions. -It then either lists the possible completions, inserts the possible -completions, or actually performs the -completion, depending on which behavior is desired. - -@item -The internal function @code{rl_completion_matches()} uses an -application-supplied @dfn{generator} function to generate the list of -possible matches, and then returns the array of these matches. -The caller should place the address of its generator function in -@code{rl_completion_entry_function}. - -@item -The generator function is called repeatedly from -@code{rl_completion_matches()}, returning a string each time. The -arguments to the generator function are @var{text} and @var{state}. -@var{text} is the partial word to be completed. @var{state} is zero the -first time the function is called, allowing the generator to perform -any necessary initialization, and a positive non-zero integer for -each subsequent call. The generator function returns -@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are -no more possibilities left. Usually the generator function computes the -list of possible completions when @var{state} is zero, and returns them -one at a time on subsequent calls. Each string the generator function -returns as a match must be allocated with @code{malloc()}; Readline -frees the strings when it has finished with them. -Such a generator function is referred to as an -@dfn{application-specific completion function}. - -@end enumerate - -@deftypefun int rl_complete (int ignore, int invoking_key) -Complete the word at or before point.

You can only do this if -the prior command is @kbd{C-y} or @kbd{M-y}. -@end table - -@node Readline Arguments -@subsection Readline Arguments - -You can pass numeric arguments to Readline commands. Sometimes the -argument acts as a repeat count, other times it is the @i{sign} of the -argument that is significant. If you pass a negative argument to a -command which normally acts in a forward direction, that command will -act in a backward direction. For example, to kill text back to the -start of the line, you might type @samp{M-- C-k}. - -The general way to pass numeric arguments to a command is to type meta -digits before the command. If the first `digit' typed is a minus -sign (@samp{-}), then the sign of the argument will be negative. Once -you have typed one meta digit to get the argument started, you can type -the remainder of the digits, and then the command. For example, to give -the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}, -which will delete the next ten characters on the input line. - -@node Searching -@subsection Searching for Commands in the History - -Readline provides commands for searching through the command history -@ifset BashFeatures -(@pxref{Bash History Facilities}) -@end ifset -for lines containing a specified string. -There are two search modes: @dfn{incremental} and @dfn{non-incremental}. - -Incremental searches begin before the user has finished typing the -search string. -As each character of the search string is typed, Readline displays -the next entry from the history matching the string typed so far. -An incremental search requires only as many characters as needed to -find the desired history entry. -To search backward in the history for a particular string, type -@kbd{C-r}. Typing @kbd{C-s} searches forward through the history. -The characters present in the value of the @code{isearch-terminators} variable -are used to terminate an incremental search. -If that variable has not been assigned a value, the @key{ESC} and -@kbd{C-J} characters will terminate an incremental search. -@kbd{C-g} will abort an incremental search and restore the original line. -When the search is terminated, the history entry containing the -search string becomes the current line. - -To find other matching entries in the history list, type @kbd{C-r} or -@kbd{C-s} as appropriate. -This will search backward or forward in the history for the next -entry matching the search string typed so far. -Any other key sequence bound to a Readline command will terminate -the search and execute that command. -For instance, a @key{RET} will terminate the search and accept -the line, thereby executing the command from the history list. -A movement command will terminate the search, make the last line found -the current line, and begin editing. - -Readline remembers the last incremental search string. If two -@kbd{C-r}s are typed without any intervening characters defining a new -search string, any remembered search string is used. - -Non-incremental searches read the entire search string before starting -to search for matching history lines.

The word on the right side of the -@samp{=} is tested against both the full name of the terminal and -the portion of the terminal name before the first @samp{-}. This -allows @code{sun} to match both @code{sun} and @code{sun-cmd}, -for instance. - -@item application -The @var{application} construct is used to include -application-specific settings. Each program using the Readline -library sets the @var{application name}, and you can test for -a particular value. -This could be used to bind key sequences to functions useful for -a specific program.

The first is the ability to interactively change the - * prompt, which can't be done using the regular interface since rl_prompt is - * read-only. - * - * The second feature really highlights a subtle point when using the alternate - * interface. That is, readline will not alter the terminal when inside your - * callback handler. So let's so, your callback executes a user command that - * takes a non-trivial amount of time to complete (seconds). While your - * executing the command, the user continues to type keystrokes and expects them - * to be re-echoed on the new prompt when it returns. Unfortunately, the default - * terminal configuration doesn't do this. After the prompt returns, the user - * must hit one additional keystroke and then will see all of his previous - * keystrokes. To illustrate this, compile and run this program. Type "sleep" at - * the prompt and then type "bar" before the prompt returns (you have 3 - * seconds). Notice how "bar" is re-echoed on the prompt after the prompt - * returns? This is what you expect to happen. Now comment out the 4 lines below - * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do - * the same thing. When the prompt returns, you should not see "bar". Now type - * "f", see how "barf" magically appears?

The generic method for 32-bit platforms is to - put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths) - in the LD_PRELOAD environment variable, and to put their parent directories - in the LD_LIBRARY_PATH environment variable. Unfortunately there is no - generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have - to build both 32-bit and 64-bit libfgets and libreadline libraries, and - use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and - library_path configurations (a mix of 32-bit and 64-bit calls are made under - 64-bit SunOS). - - EXAMPLE WRAPPER: Here is an example shell script wrapper around the - program "foo" that uses fgets() for command-line input: - - #!/bin/csh - #### replace this with the libtermcap.so directory: - set dir1 = "/usr/lib" - #### replace this with the libfgets.so directory: - set dir2 = "/usr/fgets" - #### replace this with the libreadline.so directory: - set dir3 = "/usr/local/lib" - set lib1 = "${dir1}/libtermcap.so" - set lib2 = "${dir2}/libfgets.so" - set lib3 = "${dir3}/libreadline.so" - if ( "${?LD_PRELOAD}" ) then - setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}" - else - setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}" - endif - if ( "${?LD_LIBRARY_PATH}" ) then - setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}" - else - setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}" - endif - setenv FGETS_COMMAND_FILE "${dir2}/foo.commands" - setenv FGETS_PROMPT "foo> " - exec "foo" $* - - Copyright (C)©2003-2004 Harold Levy. - - This code links to the GNU readline library, and as such is bound by the - terms of the GNU General Public License as published by the Free Software - Foundation, either version 2 or (at your option) any later version. - - The GNU General Public License is often shipped with GNU software, and is - generally kept in a file called COPYING or LICENSE.
