Move readline to the readline/readline subdirectory
readline turns out to be a bit of a stumbling block for the project to
move gdbsupport (and then gdbserver) to the top-level.
The issue is that readline headers are intended to be included with
names like "readline/readline.h". To support this, gdb effectively
adds a -I option pointing to the top-level source directory -- but,
importantly, this option is not used when the system readline is used.
For gdbsupport, a -I option like this would always be needed, but that
in turn would break the system readline case. This was PR build/17077,
fixed in commit a8a5dbcab8df0b3a9e04745d4fe8d64740acb323.
Previously, we had discussed this on the gdb-patches list in terms of
removing readline from the tree
https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html
However, Eli expressed some concerns, and Joel did as well (off-list).
Given those concerns, and the fact that a patch-free local readline is
relatively new in gdb (it was locally patched for years), I changed my
mind and decided to handle this situation by moving the readline
sources down a level.
That is, upstream readline is now in readline/readline, and the
top-level readline directory just contains the minimal configury
needed to build that.
This fixes the problem because, when gdb unconditionally adds a
-I$(top_srcdir), this will not find readline headers. A separate -I
will be needed instead, which is exactly what's needed for
--with-system-readline.

Changes to Readline + +a. Added a guard to prevent nested macros from causing an infinite expansion + loop. + +b. Instead of allocating enough history list entries to hold the maximum list + size, cap the number allocated initially. + +c. Added a strategy to avoid allocating huge amounts of memory if a block of + history entries without timestamps occurs after a block with timestamps. + +d. Added support for keyboard timeouts when an ESC character is the last + character in a macro. + +e. There are several performance improvements when in a UTF-8 locale. + +f. Readline does a better job of preserving the original set of blocked + signals when using pselect() to wait for input. + +g. Fixed a bug that caused multibyte characters in macros to be mishandled. + +h. Fixed several bugs in the code that calculates line breaks when expanding + prompts that span several lines, contain multibyte characters, and contain + invisible character seqeuences. + +i. Fixed several bugs in cursor positioning when displaying lines with prompts + containing invisible characters and multibyte characters. + +j. When performing case-insensitive completion, Readline no longer sorts the + list of matches unless directed to do so. + +k. Fixed a problem with key sequences ending with a backslash. + +l. Fixed out-of-bounds and free memory read errors found via fuzzing. + +m. Fixed several cases where the mark was set to an invalid value. + +n. Fixed a problem with the case-changing operators in the case where the + lower and upper case versions of a character do not have the same number + of bytes. + +o. Handle incremental and non-incremental search character reads returning EOF. + +p. Handle the case where a failing readline command at the end of a multi-key + sequence could be misinterpreted. + +q. The history library now prints a meaningful error message if the history + file isn't a regular file. + +r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace + a multibyte character. + +s. The key binding code now attempts to remove a keymap if a key unbinding + leaves it empty. + +t. Fixed a line-wrapping issue that caused problems for some terminal + emulators. + +u. If there is a key bound to the tty's VDISCARD special character, readline + disables VDISCARD while it is active. + +v. Fixed a problem with exiting bracketed paste mode on terminals that assume + the bracketed paste mode character sequence contains visible characters. + +w. Fixed a bug that could cause a key binding command to refer to an + uninitialized variable. + +x. Added more UTF-8-specific versions of multibyte functions, and optimized + existing functions if the current locale uses UTF-8 encoding. + +y. Fixed a problem with bracketed-paste inserting more than one character and + interacting with other readline functions. + +z. Fixed a bug that caused the history library to attempt to append a history + line to a non-existent history entry. + +aa. If using bracketed paste mode, output a newline after the \r that is the + last character of the mode disable string to avoid overwriting output. + +bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better + handle multibyte characters. + +cc. Fixed a redisplay problem that caused an extra newline to be generated on + accept-line when the line length is exactly the screenwidth. + +dd. Fixed a bug with adding multibyte characters to an incremental search + string. + +ee. Fixed a bug with redoing text insertions in vi mode. + +ff. Fixed a bug with pasting text into an incremental search string if bracketed + paste mode is enabled. ESC cannot be one of the incremental search + terminator characters for this to work. + +gg. Fixed a bug with anchored search patterns when performing searches in vi + mode. + +2. New Features in Readline + +a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as + Posix specifies (uses fnmatch(3) if available). + +b. There are new `next-screen-line' and `previous-screen-line' bindable + commands, which move the cursor to the same column in the next, or previous, + physical line, respectively. + +c. There are default key bindings for control-arrow-key key combinations. + +d. A negative argument (-N) to `quoted-insert' means to insert the next N + characters using quoted-insert. + +e. New public function: rl_check_signals(), which allows applications to + respond to signals that readline catches while waiting for input using + a custom read function. + +f. There is new support for conditionally testing the readline version in an + inputrc file, with a full set of arithmetic comparison operators available. + +g. There is a simple variable comparison facility available for use within an + inputrc file. Allowable operators are equality and inequality; string + variables may be compared to a value; boolean variables must be compared to + either `on' or `off'; variable names are separated from the operator by + whitespace. + +h. The history expansion library now understands command and process + substitution and extended globbing and allows them to appear anywhere in a + word. + +i. The history library has a new variable that allows applications to set the + initial quoting state, so quoting state can be inherited from a previous + line. + +j. Readline now allows application-defined keymap names; there is a new public + function, rl_set_keymap_name(), to do that. + +k. The "Insert" keypad key, if available, now puts readline into overwrite + mode. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-7.0, and the +previous version, readline-6.3. + +1. Changes to Readline + +a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y' + commands with modifiers was fixed. + +b. Fixed a bug that caused callback mode to dump core when reading a + multiple-key sequence (e.g., arrow keys). + +c. Fixed a bug that caused the redisplay code to erase some of the line when + using horizontal scrolling with incremental search. + +d. Readline's input handler now performs signal processing if read(2) is + interrupted by SIGALRM or SIGVTALRM. + +e. Fixed a problem with revert-all-at-newline freeing freed memory. + +f. Clarified the documentation for the history_quotes_inhibit_expansion + variable to note that it inhibits scanning for the history comment + character and that it only affects double-quoted strings. + +g. Fixed an off-by-one error in the prompt printed when performing searches. + +h. Use pselect(2), if available, to wait for input before calling read(2), so + a SIGWINCH can interrupt it, since it doesn't interrupt read(2). + +i. Some memory leaks caused by signals interrupting filename completion have + been fixed. + +j. Reading EOF twice on a non-empty line causes EOF to be returned, rather + than the partial line. This can cause partial lines to be executed on + SIGHUP, for example. + +k. Fixed a bug concerning deleting multibyte characters from the search + string while performing an incremental search. + +l. Fixed a bug with tilde expanding directory names in filename completion. + +m. Fixed a bug that did not allow binding sequences beginning with a `\'. + +n. Fixed a redisplay bug involving incorrect line wrapping when the prompt + contains a multibyte character in the last screen column. + +o. Fixed a bug that caused history expansion to disregard characters that are + documented to delimit a history event specifier without requiring `:'. + +p. Fixed a bug that could cause reading past the end of a string when reading + the value when binding the set of isearch terminators. + +q. Fixed a bug that caused readline commands that depend on knowing which + key invoked them to misbehave when dispatching key sequences that are + prefixes of other key bindings. + +r. Paren matching now works in vi insert mode. + +s. Colored completion prefixes are now displayed using a different color, less + likely to collide with files. + +t. Fixed a bug that caused vi-mode character search to misbehave when + running in callback mode. + +u. Fixed a bug that caused output to be delayed when input is coming from a + macro in vi-mode. + +v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing + a multi-key key sequence via a macro. + +w. Fixed a bug that caused problems with applications that supply their own + input function when performing completion. + +x. When read returns -1/EIO when attempting to read a key, return an error + instead of line termination back to the caller. + +y. Updated tty auditing feature based on patch from Red Hat. + +z. Fixed a bug that could cause the history library to crash on overflows + introduced by malicious editing of timestamps in the history file. + +aa. The history file writing functions only attempt to create and use a backup + history file if the history file exists and is a regular file. + +bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface. + +cc. Fixed several redisplay bugs with prompt strings containing multibyte + and non-visible characters whose physical length is longer than the screen + width. + +dd. Fixed a redisplay bug with prompt strings containing invisible characters + whose physical length exceeds the screen width and using incremental search. + +ee. Readline prints more descriptive error messages when it encounters errors + while reading an inputrc file. + +ff. Fixed a bug in the character insertion code that attempts to optimize + typeahead when it reads a character that is not bound to self-insert and + resets the key sequence state. + +gg. When refreshing the line as the result of a key sequence, Readline attempts + to redraw only the last line of a multiline prompt. + +hh. Fixed an issue that caused completion of git commands to display + incorrectly when using colored-completion-prefix. + +ii. Fixed several redisplay bugs having to do with multibyte characters and + invisible characters in prompt strings. + +jj. Fixed a bug that caused mode strings to be displayed incorrectly if the + prompt was shorter than the mode string. + +2. New Features in Readline + +a. The history truncation code now uses the same error recovery mechansim as + the history writing code, and restores the old version of the history file + on error. The error recovery mechanism handles symlinked history files. + +b. There is a new bindable variable, `enable-bracketed-paste', which enables + support for a terminal's bracketed paste mode. + +c. The editing mode indicators can now be strings and are user-settable + (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string' + variables). Mode strings can contain invisible character sequences. + Setting mode strings to null strings restores the defaults. + +d. Prompt expansion adds the mode string to the last line of a multi-line + prompt (one with embedded newlines). + +e. There is a new bindable variable, `colored-completion-prefix', which, if + set, causes the common prefix of a set of possible completions to be + displayed in color. + +f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs- + mode yank-pop. + +g. The redisplay code underwent several efficiency improvements for multibyte + locales. + +h. The insert-char function attempts to batch-insert all pending typeahead + that maps to self-insert, as long as it is coming from the terminal. + +i. rl_callback_sigcleanup: a new application function that can clean up and + unset any state set by readline's callback mode. Intended to be used + after a signal. + +j. If an incremental search string has its last character removed with DEL, the + resulting empty search string no longer matches the previous line. + +k. If readline reads a history file that begins with `#' (or the value of + the history comment character) and has enabled history timestamps, the history + entries are assumed to be delimited by timestamps. This allows multi-line + history entries. + +l. Readline now throws an error if it parses a key binding without a terminating + `:' or whitespace. + +m. The default binding for ^W in vi mode now uses word boundaries specified + by Posix (vi-unix-word-rubout is bindable command name). + +n. rl_clear_visible_line: new application-callable function; clears all + screen lines occupied by the current visible readline line. + +o. rl_tty_set_echoing: application-callable function that controls whether + or not readline thinks it is echoing terminal output. + +p. Handle >| and strings of digits preceding and following redirection + specifications as single tokens when tokenizing the line for history + expansion. + +q. Fixed a bug with displaying completions when the prefix display length + is greater than the length of the completions to be displayed. + +r. The :p history modifier now applies to the entire line, so any expansion + specifying :p causes the line to be printed instead of expanded. + +s. New application-callable function: rl_pending_signal(): returns the signal + number of any signal readline has caught but not yet handled. + +t. New application-settable variable: rl_persistent_signal_handlers: if set + to a non-zero value, readline will enable the readline-6.2 signal handler + behavior in callback mode: handlers are installed when + rl_callback_handler_install is called and removed removed when a complete + line has been read. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-6.3, and the +previous version, readline-6.2. + +1. Changes to Readline + +a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode + commands to work on the entire line. + +b. Fixed a bug that caused redisplay problems with prompts longer than 128 + characters and history searches. + +c. Fixed a bug that caused readline to try and run code to modify its idea + of the screen size in a signal handler context upon receiving a SIGWINCH. + +d. Fixed a bug that caused the `meta' key to be enabled beyond the duration + of an individual call top readline(). + +e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's + redisplay to mishandle zero-width combining characters. + +f. Fixed a bug that caused readline to `forget' part of a key sequence when + a multiple-key sequence caused it to break out of an incremental search. + +g. Fixed bugs that caused readline to execute code in a signal handler + context if interrupted while reading from the file system during completion. + +h. Fixed a bug that caused readline to `forget' part of a key sequence when + reading an unbound multi-character key sequence. + +i. Fixed a bug that caused Readline's signal handlers to be installed beyond + the bounds of a single call to readline(). + +j. Fixed a bug that caused the `.' command to not redo the most recent `R' + command in vi mode. + +k. Fixed a bug that caused ignoring case in completion matches to result in + readline using the wrong match. + +l. Paren matching now works in vi insert mode. + +m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix + work together. + +n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone + in vi editing mode. + +o. Fixed a bug that caused the filename comparison code to not compare + multibyte characters correctly when using case-sensitive or case-mapping + comparisons. + +p. Fixed the input reading loop to call the input hook function only when there + is no terminal input available. + +q. Fixed a bug that caused binding a macro to a multi-character key sequence + where the sequence and macro value share a common prefix to not perform + the macro replacement. + +r. Fixed several redisplay errors with multibyte characters and prompts + containing invisible characters when using horizontal scrolling. + +s. Fixed a bug that caused redisplay errors when trying to overwrite + existing characters using multibyte characters. + +t. Fixed a bug in vi mode that caused the arrow keys to set the saved last + vi-mode command to the wrong value. + +u. Fixed a bug that caused double-quoted strings to be scanned incorrectly + when being used as the value of a readline variable assignment. + +v. Fixed a bug with vi mode that prevented `.' from repeating a command + entered on a previous line (command). + +w. Fixed a bug that could cause completion to core dump if it was interrupted + by a signal. + +x. Fixed a bug that could cause readline to crash and seg fault attempting to + expand an empty history entry. + +y. Fixed a bug that caused display problems with multi-line prompts containing + invisible characters on multiple lines. + +z. Fixed a bug that caused effects made by undoing changes to a history line to + be discarded. + +2. New Features in Readline + +a. Readline is now more responsive to SIGHUP and other fatal signals when + reading input from the terminal or performing word completion but no + longer attempts to run any not-allowable functions from a signal handler + context. + +b. There are new bindable commands to search the history for the string of + characters between the beginning of the line and the point + (history-substring-search-forward, history-substring-search-backward) + +c. Readline allows quoted strings as the values of variables when setting + them with `set'. As a side effect, trailing spaces and tabs are ignored + when setting a string variable's value. + +d. The history library creates a backup of the history file when writing it + and restores the backup on a write error. + +e. New application-settable variable: rl_filename_stat_hook: a function called + with a filename before using it in a call to stat(2). Bash uses it to + expand shell variables so things like $HOME/Downloads have a slash + appended. + +f. New bindable function `print-last-kbd-macro', prints the most-recently- + defined keyboard macro in a reusable format. + +g. New user-settable variable `colored-stats', enables use of colored text + to denote file types when displaying possible completions (colored analog + of visible-stats). + +h. New user-settable variable `keyseq-timout', acts as an inter-character + timeout when reading input or incremental search strings. + +i. New application-callable function: rl_clear_history. Clears the history list + and frees all readline-associated private data. + +j. New user-settable variable, show-mode-in-prompt, adds a characters to the + beginning of the prompt indicating the current editing mode. + +k. New application-settable variable: rl_input_available_hook; function to be + called when readline needs to check whether there is data available on its + input source. The default hook checks rl_instream. + +l. Readline calls an application-set event hook (rl_signal_event_hook) after + it gets a signal while reading input (read returns -1/EINTR but readline + does not handle the signal immediately) to allow the application to handle + or otherwise note it. Not currently called for SIGHUP or SIGTERM. + +m. If the user-settable variable `history-size' is set to a value less than + 0, the history list size is unlimited. + +n. When creating shared libraries on Mac OS X, the pathname written into the + library (install_name) no longer includes the minor version number. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-6.2, +and the previous version, readline-6.1. + +1. Changes to Readline + +a. Fixed a bug that caused the unconverted filename to be added to the list of + completions when the application specified filename conversion functions. + +b. Fixed a bug that caused the wrong filename to be passed to opendir when the + application has specified a filename dequoting function. + +c. Fixed a bug when repeating a character search in vi mode in the case where + there was no search to repeat. + +d. When show-all-if-ambiguous is set, the completion routines no longer insert + a common match prefix that is shorter than the text being completed. + +e. The full set of vi editing commands may now be used in callback mode. + +f. Fixed a bug that caused readline to not update its idea of the terminal + dimensions while running in `no-echo' mode. + +h. Fixed a bug that caused readline to dump core if an application called + rl_prep_terminal without setting rl_instream. + +i. Fixed a bug that caused meta-prefixed characters bound to incremental + search forward or backward to not be recognized if they were typed + subsequently. + +j. The incremental search code treats key sequences that map to the same + functions as (default) ^G, ^W, and ^Y as equivalent to those characters. + +k. Fixed a bug in menu-complete that caused it to misbehave with large + negative argument. + +l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked + at the end of the line. + +m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave + as if it were a negative argument. + +n. Fixed a bug that caused directory names in words to be completed to not + be dequoted correctly. + +2. New Features in Readline + +a. The history library does not try to write the history filename in the + current directory if $HOME is unset. This closes a potential security + problem if the application does not specify a history filename. + +b. New bindable variable `completion-display-width' to set the number of + columns used when displaying completions. + +c. New bindable variable `completion-case-map' to cause case-insensitive + completion to treat `-' and `_' as identical. + +d. There are new bindable vi-mode command names to avoid readline's case- + insensitive matching not allowing them to be bound separately. + +e. New bindable variable `menu-complete-display-prefix' causes the menu + completion code to display the common prefix of the possible completions + before cycling through the list, instead of after. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-6.1, +and the previous version, readline-6.0. + +1. Changes to Readline + +a. The SIGWINCH signal handler now avoids calling the redisplay code if + one arrives while in the middle of redisplay. + +b. Changes to the timeout code to make sure that timeout values greater + than one second are handled better. + +c. Fixed a bug in the redisplay code that was triggered by a prompt + containing invisible characters exactly the width of the screen. + +d. Fixed a bug in the redisplay code encountered when running in horizontal + scroll mode. + +e. Fixed a bug that prevented menu completion from properly completing + filenames. + +f. Fixed a redisplay bug caused by a multibyte character causing a line to + wrap. + +g. Fixed a bug that caused key sequences of two characters to not be + recognized when a longer sequence identical in the first two characters + was bound. + +h. Fixed a bug that caused history expansion to be attempted on $'...' + single-quoted strings. + +i. Fixed a bug that caused incorrect redisplay when the prompt contained + multibyte characters in an `invisible' sequence bracketed by \[ and + \]. + +j. Fixed a bug that caused history expansion to short-circuit after + encountering a multibyte character. + +k. Fixed a bug that caused applications using the callback interface to not + react to SIGINT (or other signals) until another character arrived. + +2. New Features in Readline + +a. New bindable function: menu-complete-backward. + +b. In the vi insertion keymap, C-n is now bound to menu-complete by default, + and C-p to menu-complete-backward. + +c. When in vi command mode, repeatedly hitting ESC now does nothing, even + when ESC introduces a bound key sequence. This is closer to how + historical vi behaves. + +d. New bindable function: skip-csi-sequence. Can be used as a default to + consume key sequences generated by keys like Home and End without having + to bind all keys. + +e. New application-settable function: rl_filename_rewrite_hook. Can be used + to rewite or modify filenames read from the file system before they are + compared to the word to be completed. + +f. New bindable variable: skip-completed-text, active when completing in the + middle of a word. If enabled, it means that characters in the completion + that match characters in the remainder of the word are "skipped" rather + than inserted into the line. + +g. The pre-readline-6.0 version of menu completion is available as + "old-menu-complete" for users who do not like the readline-6.0 version. + +h. New bindable variable: echo-control-characters. If enabled, and the + tty ECHOCTL bit is set, controls the echoing of characters corresponding + to keyboard-generated signals. + +i. New bindable variable: enable-meta-key. Controls whether or not readline + sends the smm/rmm sequences if the terminal indicates it has a meta key + that enables eight-bit characters. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-6.0, +and the previous version, readline-5.2. + +1. Changes to Readline + +a. Fixed a number of redisplay errors in environments supporting multibyte + characters. + +b. Fixed bugs in vi command mode that caused motion commands to inappropriately + set the mark. + +c. When using the arrow keys in vi insertion mode, readline allows movement + beyond the current end of the line (unlike command mode). + +d. Fixed bugs that caused readline to loop when the terminal has been taken + away and reads return -1/EIO. + +e. Fixed bugs in redisplay occurring when displaying prompts containing + invisible characters. + +f. Fixed a bug that caused the completion append character to not be reset to + the default after an application-specified completion function changed it. + +g. Fixed a problem that caused incorrect positioning of the cursor while in + emacs editing mode when moving forward at the end of a line while using + a locale supporting multibyte characters. + +h. Fixed an off-by-one error that caused readline to drop every 511th + character of buffered input. + +i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up. + +j. Fixed redisplay bugs caused by multiline prompts with invisible characters + or no characters following the final newline. + +k. Fixed redisplay bug caused by prompts consisting solely of invisible + characters. + +l. Fixed a bug in the code that buffers characters received very quickly in + succession which caused characters to be dropped. + +m. Fixed a bug that caused readline to reference uninitialized data structures + if it received a SIGWINCH before completing initialzation. + +n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly + and therefore unrepeatable. + +o. Fixed a bug that caused readline to disable echoing when it was being used + with an output file descriptor that was not a terminal. + +p. Readline now blocks SIGINT while manipulating internal data structures + during redisplay. + +q. Fixed a bug in redisplay that caused readline to segfault when pasting a + very long line (over 130,000 characters). + +r. Fixed bugs in redisplay when using prompts with no visible printing + characters. + +s. Fixed a bug that caused redisplay errors when using prompts with invisible + characters and numeric arguments to a command in a multibyte locale. + +t. Fixed a bug that caused redisplay errors when using prompts with invisible + characters spanning more than two physical screen lines. + +2. New Features in Readline + +a. A new variable, rl_sort_completion_matches; allows applications to inhibit + match list sorting (but beware: some things don't work right if + applications do this). + +b. A new variable, rl_completion_invoking_key; allows applications to discover + the key that invoked rl_complete or rl_menu_complete. + +c. The functions rl_block_sigint and rl_release_sigint are now public and + available to calling applications who want to protect critical sections + (like redisplay). + +d. The functions rl_save_state and rl_restore_state are now public and + available to calling applications; documented rest of readline's state + flag values. + +e. A new user-settable variable, `history-size', allows setting the maximum + number of entries in the history list. + +f. There is a new implementation of menu completion, with several improvements + over the old; the most notable improvement is a better `completions + browsing' mode. + +g. The menu completion code now uses the rl_menu_completion_entry_function + variable, allowing applications to provide their own menu completion + generators. + +h. There is support for replacing a prefix of a pathname with a `...' when + displaying possible completions. This is controllable by setting the + `completion-prefix-display-length' variable. Matches with a common prefix + longer than this value have the common prefix replaced with `...'. + +i. There is a new `revert-all-at-newline' variable. If enabled, readline will + undo all outstanding changes to all history lines when `accept-line' is + executed. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-5.2, +and the previous version, readline-5.1. + +1. Changes to Readline + +a. Fixed a problem that caused segmentation faults when using readline in + callback mode and typing consecutive DEL characters on an empty line. + +b. Fixed several redisplay problems with multibyte characters, all having to + do with the different code paths and variable meanings between single-byte + and multibyte character redisplay. + +c. Fixed a problem with key sequence translation when presented with the + sequence \M-\C-x. + +d. Fixed a problem that prevented the `a' command in vi mode from being + undone and redone properly. + +e. Fixed a problem that prevented empty inserts in vi mode from being undone + properly. + +f. Fixed a problem that caused readline to initialize with an incorrect idea + of whether or not the terminal can autowrap. + +g. 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 with creating the prompt for a non-interactive search string + when there are non-printing characters in the primary prompt. + +j. Fixed a bug that caused prompts with invisible characters to be redrawn + multiple times in a multibyte locale. + +k. Fixed a bug that could cause the key sequence scanning code to return the + wrong function. + +l. Fixed a problem with the callback interface that caused it to fail when + using multi-character keyboard macros. + +m. Fixed a bug that could cause a core dump when an edited history entry was + re-executed under certain conditions. + +n. Fixed a bug that caused readline to reference freed memory when attmpting + to display a portion of the prompt. + +o. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing + the prompt and input line multiple times. + +p. Fixed history expansion to not be confused by here-string redirection. + +q. Readline no longer treats read errors by converting them to newlines, as + it does with EOF. This caused partial lines to be returned from readline(). + +r. Fixed a redisplay bug that occurred in multibyte-capable locales when the + prompt was one character longer than the screen width. + +2. New Features in Readline + +a. Calling applications can now set the keyboard timeout to 0, allowing + poll-like behavior. + +b. The value of SYS_INPUTRC (configurable at compilation time) is now used as + the default last-ditch startup file. + +c. The history file reading functions now allow windows-like \r\n line + terminators. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-5.1, +and the previous version, readline-5.0. + +1. Changes to Readline + +a. Fixed a bug that caused multiliine prompts to be wrapped and displayed + incorrectly. + +b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current + line correctly. + +c. Fixed a problem in computing the number of invisible characters on the first + line of a prompt whose length exceeds the screen width. + +d. Fixed vi-mode searching so that failure preserves the current line rather + than the last line in the history list. + +e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +g. Fixed multiple bugs in the redisplay of multibyte characters: displaying + prompts longer than the screen width containing multibyte characters, + +h. Fix the calculation of the number of physical characters in the prompt + string when it contains multibyte characters. + +i. A non-zero value for the `rl_complete_suppress_append' variable now causes + no `/' to be appended to a directory name. + +j. Fixed forward-word and backward-word to work when words contained + multibyte characters. + +k. Fixed a bug in finding the delimiter of a `?' substring when performing + history expansion in a locale that supports multibyte characters. + +l. Fixed a memory leak caused by not freeing the timestamp in a history entry. + +m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting + of the `convert-meta' variable. + +n. Fixed saving and restoring primary prompt when prompting for incremental + and non-incremental searches; search prompts now display multibyte + characters correctly. + +o. Fixed a bug that caused keys originally bound to self-insert but shadowed + by a multi-character key sequence to not be inserted. + +p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't + dereferenced if NULL (matching the documentation). + +q. Extensive changes to readline to add enough state so that commands + requiring additional characters (searches, multi-key sequences, numeric + arguments, commands requiring an additional specifier character like + vi-mode change-char, etc.) work without synchronously waiting for + additional input. + +r. Lots of changes so readline builds and runs on MinGW. + +s. Readline no longer tries to modify the terminal settings when running in + callback mode. + +t. The Readline display code no longer sets the location of the last invisible + character in the prompt if the \[\] sequence is empty. + +u. The `change-case' command now correctly changes the case of multibyte + characters. + +v. Changes to the shared library construction scripts to deal with Windows + DLL naming conventions for Cygwin. + +w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed + SIGWINCH. + +x. Fixed the non-incremental search code in vi mode to dispose of any current + undo list when copying a line from the history into the current editing + buffer. + +y. Fixed a bug that caused reversing the incremental search direction to + not work correctly. + +z. Fixed the vi-mode `U' command to only undo up to the first time insert mode + was entered, as Posix specifies. + +aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong + place. + +bb. Fixed a redisplay bug caused by moving the cursor vertically to a line + with invisible characters in the prompt in a multibyte locale. + +cc. Fixed a bug that could cause the terminal special chars to be bound in the + wrong keymap in vi mode. + +2. New Features in Readline + +a. The key sequence sent by the keypad `delete' key is now automatically + bound to delete-char. + +b. A negative argument to menu-complete now cycles backward through the + completion list. + +c. A new bindable readline variable: bind-tty-special-chars. If non-zero, + readline will bind the terminal special characters to their readline + equivalents when it's called (on by default). + +d. New bindable command: vi-rubout. Saves deleted text for possible + reinsertion, as with any vi-mode `text modification' command; `X' is bound + to this in vi command mode. + +e. If the rl_completion_query_items is set to a value < 0, readline never + asks the user whether or not to view the possible completions. + +f. The `C-w' binding in incremental search now understands multibyte + characters. + +g. New application-callable auxiliary function, rl_variable_value, returns + a string corresponding to a readline variable's value. + +h. When parsing inputrc files and variable binding commands, the parser + strips trailing whitespace from values assigned to boolean variables + before checking them. + +i. A new external application-controllable variable that allows the LINES + and COLUMNS environment variables to set the window size regardless of + what the kernel returns. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-5.0, +and the previous version, readline-4.3. + +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 + <ctype.h>. + +p. Fixed a problem where rl_backward could possibly set point to before + the beginning of the line. + +q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause + include file problems. + +2. New Features in Readline + +a. Added extern declaration for rl_get_termcap to readline.h, making it a + public function (it was always there, just not in readline.h). + +b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402, + RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2. + +c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION. + +d. New bindable boolean readline variable: match-hidden-files. Controls + completion of files beginning with a `.' (on Unix). Enabled by default. + +e. The history expansion code now allows any character to terminate a + `:first-' modifier, like csh. + +f. The incremental search code remembers the last search string and uses + it if ^R^R is typed without a search string. + +h. New bindable variable `history-preserve-point'. If set, the history + code attempts to place the user at the same location on each history + line retrived with previous-history or next-history. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.2, +and the previous version, readline-4.1. + +1. Changes to Readline + +a. When setting the terminal attributes on systems using `struct termio', + readline waits for output to drain before changing the attributes. + +b. A fix was made to the history word tokenization code to avoid attempts to + dereference a null pointer. + +c. Readline now defaults rl_terminal_name to $TERM if the calling application + has left it unset, and tries to initialize with the resultant value. + +d. Instead of calling (*rl_getc_function)() directly to get input in certain + places, readline now calls rl_read_key() consistently. + +e. Fixed a bug in the completion code that allowed a backslash to quote a + single quote inside a single-quoted string. + +f. rl_prompt is no longer assigned directly from the argument to readline(), + but uses memory allocated by readline. This allows constant strings to + be passed to readline without problems arising when the prompt processing + code wants to modify the string. + +g. Fixed a bug that caused non-interactive history searches to return the + wrong line when performing multiple searches backward for the same string. + +h. Many variables, function arguments, and function return values are now + declared `const' where appropriate, to improve behavior when linking with + C++ code. + +i. The control character detection code now works better on systems where + `char' is unsigned by default. + +j. The vi-mode numeric argument is now capped at 999999, just like emacs mode. + +k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been + replaced with a set of specific prototyped typedefs, though they are + still in the readline header files for backwards compatibility. + +m. Nearly all of the (undocumented) internal global variables in the library + now have an _rl_ prefix -- there were a number that did not, like + screenheight, screenwidth, alphabetic, etc. + +n. The ding() convenience function has been renamed to rl_ding(), though the + old function is still defined for backwards compatibility. + +o. The completion convenience functions filename_completion_function, + username_completion_function, and completion_matches now have an rl_ + prefix, though the old names are still defined for backwards compatibility. + +p. The functions shared by readline and bash (linkage is satisfied from bash + when compiling with bash, and internally otherwise) now have an sh_ prefix. + +q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so + that the `soname' contains only the major version number rather than the + major and minor numbers. + +r. Fixed a redisplay bug that occurred when the prompt spanned more than one + physical line and contained invisible characters. + +s. Added a missing `includedir' variable to the Makefile. + +t. When installing the shared libraries, make sure symbolic links are relative. + +u. Added configure test so that it can set `${MAKE}' appropriately. + +v. Fixed a bug in rl_forward that could cause the point to be set to before + the beginning of the line in vi mode. + +w. Fixed a bug in the callback read-char interface to make it work when a + readline function pushes some input onto the input stream with + rl_execute_next (like the incremental search functions). + +x. Fixed a file descriptor leak in the history file manipulation code that + was tripped when attempting to truncate a non-regular file (like + /dev/null). + +y. Changes to make all of the exported readline functions declared in + readline.h have an rl_ prefix (rltty_set_default_bindings is now + rl_tty_set_default_bindings, crlf is now rl_crlf, etc.) + +z. The formatted documentation included in the base readline distribution + is no longer removed on a `make distclean'. + +aa. Some changes were made to avoid gcc warnings with -Wall. + +bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so + `set keymap EMACS' works. + +cc. The history file writing and truncation functions now return a useful + status on error. + +dd. Fixed a bug that could cause applications to dereference a NULL pointer + if a NULL second argument was passed to history_expand(). + +ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero + value, rl_read_key() now immediately returns '\n' (which is assumed to + be bound to accept-line). + +2. New Features in Readline + +a. The blink timeout for paren matching is now settable by applications, + via the rl_set_paren_blink_timeout() function. + +b. _rl_executing_macro has been renamed to rl_executing_macro, which means + it's now part of the public interface. + +c. Readline has a new variable, rl_readline_state, which is a bitmap that + encapsulates the current state of the library; intended for use by + callbacks and hook functions. + +d. rlfe has a new -l option to log input and output (-a appends to logfile), + a new -n option to set the readline application name, and -v and -h + options for version and help information. + +e. rlfe can now perform filename completion for the inferior process if the + OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the + inferior's current working directory. + +f. A new file, rltypedefs.h, contains the new typedefs for function pointers + and is installed by `make install'. + +g. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +h. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +i. The history example program (examples/histexamp.c) is now built as one + of the examples. + +j. The documentation has been updated to cover nearly all of the public + functions and variables declared in readline.h. + +k. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +l. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +m. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +n. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +o. There is a new history.3 manual page documenting the history library. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.1, +and the previous version, readline-4.0. + +1. Changes to Readline + +a. Changed the HTML documents so that the table-of-contents is no longer + a separate file. + +b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x, + OSF/1. + +c. The shared library major and minor versions are now constructed + automatically by configure and substituted into the makefiles. + +d. It's now possible to install the shared libraries separately from the + static libraries. + +e. The history library tries to truncate the history file only if it is a + regular file. + +f. A bug that caused _rl_dispatch to address negative array indices on + systems with signed chars was fixed. + +g. rl-yank-nth-arg now leaves the history position the same as when it was + called. + +h. Changes to the completion code to handle MS-DOS drive-letter:pathname + filenames. + +i. Completion is now case-insensitive by default on MS-DOS. + +j. Fixes to the history file manipulation code for MS-DOS. + +k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS. + +l. Some fixes were made to the redisplay code for better operation on MS-DOS. + +m. The quoted-insert code will now insert tty special chars like ^C. + +n. A bug was fixed that caused the display code to reference memory before + the start of the prompt string. + +o. More support for __EMX__ (OS/2). + +p. A bug was fixed in readline's signal handling that could cause infinite + recursion in signal handlers. + +q. A bug was fixed that caused the point to be less than zero when rl_forward + was given a very large numeric argument. + +r. The vi-mode code now gets characters via the application-settable value + of rl_getc_function rather than calling rl_getc directly. + +s. The history file code now uses O_BINARY mode when reading and writing + the history file on cygwin32. + +t. Fixed a bug in the redisplay code for lines with more than 256 line + breaks. + +u. A bug was fixed which caused invisible character markers to not be + stripped from the prompt string if the terminal was in no-echo mode. + +v. Readline no longer tries to get the variables it needs for redisplay + from the termcap entry if the calling application has specified its + own redisplay function. Readline treats the terminal as `dumb' in + this case. + +w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape + sequences is redrawn correctly. + +x. Changes to the install and install-shared targets so that the libraries + and header files are installed separately. + +2. New Features in Readline + +a. A new Readline `user manual' is in doc/rluserman.texinfo. + +b. Parentheses matching is now always compiled into readline, and enabled + or disabled when the value of the `blink-matching-paren' variable is + changed. + +c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename. + +d. MS-DOS systems now use ~/_history as the default history file. + +e. history-search-{forward,backward} now leave the point at the end of the + line when the string to search for is empty, like + {reverse,forward}-search-history. + +f. history-search-{forward,backward} now leave the last history line found + in the readline buffer if the second or subsequent search fails. + +g. New function for use by applications: rl_on_new_line_with_prompt, used + when an application displays the prompt itself before calling readline(). + +h. New variable for use by applications: rl_already_prompted. An application + that displays the prompt itself before calling readline() must set this to + a non-zero value. + +i. A new variable, rl_gnu_readline_p, always 1. The intent is that an + application can verify whether or not it is linked with the `real' + readline library or some substitute. + +j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program + is included in the examples subdirectory, though it is not built + by default. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.0, +and the previous version, readline-2.2. + +1. Changes to Readline + +a. The version number is now 4.0, to match the major and minor version + numbers on the shared readline and history libraries. Future + releases will maintain the identical numbering. + +b. Fixed a typo in the `make install' recipe that copied libreadline.a + to libhistory.old right after installing it. + +c. The readline and history info files are now installed out of the source + directory if they are not found in the build directory. + +d. The library no longer exports a function named `savestring' -- backwards + compatibility be damned. + +e. There is no longer any #ifdef SHELL code in the source files. + +f. Some changes were made to the key binding code to fix memory leaks and + better support Win32 systems. + +g. Fixed a silly typo in the paren matching code -- it's microseconds, not + milliseconds. + +h. The readline library should be compilable by C++ compilers. + +i. The readline.h public header file now includes function prototypes for + all readline functions, and some changes were made to fix errors in the + source files uncovered by the use of prototypes. + +j. The maximum numeric argument is now clamped at 1000000. + +k. Fixes to rl_yank_last_arg to make it behave better. + +l. Fixed a bug in the display code that caused core dumps if the prompt + string length exceeded 1024 characters. + +m. The menu completion code was fixed to properly insert a single completion + if there is only one match. + +n. A bug was fixed that caused the display code to improperly display tabs + after newlines. + +o. A fix was made to the completion code in which a typo caused the wrong + value to be passed to the function that computed the longest common + prefix of the list of matches. + +p. The completion code now checks the value of rl_filename_completion_desired, + which is set by application-supplied completion functions to indicate + that filename completion is being performed, to decide whether or not to + call an application-supplied `ignore completions' function. + +q. Code was added to the history library to catch history substitutions + using `&' without a previous history substitution or search having been + performed. + + +2. New Features in Readline + +a. There is a new script, support/shobj-conf, to do system-specific shared + object and library configuration. It generates variables for configure + to substitute into makefiles. The README file provides a detailed + explanation of the shared library creation process. + +b. Shared libraries and objects are now built in the `shlib' subdirectory. + There is a shlib/Makefile.in to control the build process. `make shared' + from the top-level directory is still the right way to build shared + versions of the libraries. + +c. rlconf.h is now installed, so applications can find out which features + have been compiled into the installed readline and history libraries. + +d. rlstdc.h is now an installed header file. + +e. Many changes to the signal handling: + o Readline now catches SIGQUIT and cleans up the tty before returning; + o A new variable, rl_catch_signals, is available to application writers + to indicate to readline whether or not it should install its own + signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP, + SIGTTIN, and SIGTTOU; + o A new variable, rl_catch_sigwinch, is available to application + writers to indicate to readline whether or not it should install its + own signal handler for SIGWINCH, which will chain to the calling + applications's SIGWINCH handler, if one is installed; + o There is a new function, rl_free_line_state, for application signal + handlers to call to free up the state associated with the current + line after receiving a signal; + o There is a new function, rl_cleanup_after_signal, to clean up the + display and terminal state after receiving a signal; + o There is a new function, rl_reset_after_signal, to reinitialize the + terminal and display state after an application signal handler + returns and readline continues + +f. There is a new function, rl_resize_terminal, to reset readline's idea of + the screen size after a SIGWINCH. + +g. New public functions: rl_save_prompt and rl_restore_prompt. These were + previously private functions with a `_' prefix. These functions are + used when an application wants to write a message to the `message area' + with rl_message and have the prompt restored correctly when the message + is erased. + +h. New function hook: rl_pre_input_hook, called just before readline starts + reading input, after initialization. + +i. New function hook: rl_display_matches_hook, called when readline would + display the list of completion matches. The new function + rl_display_match_list is what readline uses internally, and is available + for use by application functions called via this hook. + +j. New bindable function, delete-char-or-list, like tcsh. + +k. A new variable, rl_erase_empty_line, which, if set by an application using + readline, will cause readline to erase, prompt and all, lines on which the + only thing typed was a newline. + +l. There is a new script, support/shlib-install, to install and uninstall + the shared readline and history libraries. + +m. A new bindable variable, `isearch-terminators', which is a string + containing the set of characters that should terminate an incremental + search without being executed as a command. + +n. A new bindable function, forward-backward-delete-char. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-2.2, +and the previous version, readline-2.1. + +1. Changes to Readline + +a. Added a missing `extern' to a declaration in readline.h that kept + readline from compiling cleanly on some systems. + +b. The history file is now opened with mode 0600 when it is written for + better security. + +c. Changes were made to the SIGWINCH handling code so that prompt redisplay + is done better. + +d. ^G now interrupts incremental searches correctly. + +e. A bug that caused a core dump when the set of characters to be quoted + when completing words was empty was fixed. + +f. Fixed a problem in the readline test program rltest.c that caused a core + dump. + +g. The code that handles parser directives in inputrc files now displays + more error messages. + +h. The history expansion code was fixed so that the appearance of the + history comment character at the beginning of a word inhibits history + expansion for that word and the rest of the input line. + +i. The code that prints completion listings now behaves better if one or + more of the filenames contains non-printable characters. + +j. The time delay when showing matching parentheses is now 0.5 seconds. + + +2. New Features in Readline + +a. There is now an option for `iterative' yank-last-arg handline, so a user + can keep entering `M-.', yanking the last argument of successive history + lines. + +b. New variable, `print-completions-horizontally', which causes completion + matches to be displayed across the screen (like `ls -x') rather than up + and down the screen (like `ls'). + +c. New variable, `completion-ignore-case', which causes filename completion + and matching to be performed case-insensitively. + +d. There is a new bindable command, `magic-space', which causes history + expansion to be performed on the current readline buffer and a space to + be inserted into the result. + +e. There is a new bindable command, `menu-complete', which enables tcsh-like + menu completion (successive executions of menu-complete insert a single + completion match, cycling through the list of possible completions). + +f. There is a new bindable command, `paste-from-clipboard', for use on Win32 + systems, to insert the text from the Win32 clipboard into the editing + buffer. + +g. The key sequence translation code now understands printf-style backslash + escape sequences, including \NNN octal escapes. These escape sequences + may be used in key sequence definitions or macro values. + +h. An `$include' inputrc file parser directive has been added. diff --git a/readline/readline/COPYING b/readline/readline/COPYING new file mode 100644 index 00000000000..94a9ed024d3 --- /dev/null +++ b/readline/readline/COPYING @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey 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; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If 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 convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU 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 that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + 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. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +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. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + 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 +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + 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 3 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 <bug-readline@gnu.org> 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/readline/readline/MANIFEST b/readline/readline/MANIFEST new file mode 100644 index 00000000000..ad49d6686b0 --- /dev/null +++ b/readline/readline/MANIFEST @@ -0,0 +1,165 @@ +# +# Master distribution manifest for the standalone readline distribution +# +doc d +examples d +examples/autoconf 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.ac f +Makefile.in f +readline.pc.in f +ansi_stdlib.h f +chardefs.h f +colors.h f +history.h f +histlib.h f +keymaps.h f +parse-colors.h f +posixdir.h f +posixjmp.h f +posixselect.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 +colors.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 +parse-colors.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 +xfree.c f +xmalloc.c f +history.c f +histexpand.c f +histfile.c f +histsearch.c f +patchlevel 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/rlbasic.c f +examples/rlcat.c f +examples/rlevent.c f +examples/rlkeymaps.c f +examples/rltest.c f +examples/rl-callbacktest.c f +examples/rl.c f +examples/rlptytest.c f +examples/rlversion.c f +examples/histexamp.c f +examples/hist_erasedups.c f +examples/hist_purgecmd.c f +examples/Inputrc f +examples/autoconf/BASH_CHECK_LIB_TERMCAP f +examples/autoconf/RL_LIB_READLINE_VERSION f +examples/autoconf/wi_LIB_READLINE 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 +examples/rlwrap-0.30.tar.gz 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/readline/readline/Makefile.in b/readline/readline/Makefile.in new file mode 100644 index 00000000000..bcbd18b662a --- /dev/null +++ b/readline/readline/Makefile.in @@ -0,0 +1,616 @@ +## -*- text -*- ## +# Master Makefile for the GNU readline library. +# Copyright (C) 1994-2018 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 3 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.

terse description of the new features added to readline-8.0 since +the release of readline-7.0. + +New Features in Readline + +a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as + Posix specifies (uses fnmatch(3) if available). + +b. There are new `next-screen-line' and `previous-screen-line' bindable + commands, which move the cursor to the same column in the next, or previous, + physical line, respectively. + +c. There are default key bindings for control-arrow-key key combinations. + +d. A negative argument (-N) to `quoted-insert' means to insert the next N + characters using quoted-insert. + +e. New public function: rl_check_signals(), which allows applications to + respond to signals that readline catches while waiting for input using + a custom read function. + +f. There is new support for conditionally testing the readline version in an + inputrc file, with a full set of arithmetic comparison operators available. + +g. There is a simple variable comparison facility available for use within an + inputrc file. Allowable operators are equality and inequality; string + variables may be compared to a value; boolean variables must be compared to + either `on' or `off'; variable names are separated from the operator by + whitespace. + +h. The history expansion library now understands command and process + substitution and extended globbing and allows them to appear anywhere in a + word. + +i. The history library has a new variable that allows applications to set the + initial quoting state, so quoting state can be inherited from a previous + line. + +j. Readline now allows application-defined keymap names; there is a new public + function, rl_set_keymap_name(), to do that. + +k. The "Insert" keypad key, if available, now puts readline into overwrite + mode. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to readline-7.0 since +the release of readline-6.3. + +New Features in Readline + +a. The history truncation code now uses the same error recovery mechansim as + the history writing code, and restores the old version of the history file + on error. The error recovery mechanism handles symlinked history files. + +b. There is a new bindable variable, `enable-bracketed-paste', which enables + support for a terminal's bracketed paste mode. + +c. The editing mode indicators can now be strings and are user-settable + (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string' + variables). Mode strings can contain invisible character sequences. + Setting mode strings to null strings restores the defaults. + +d. Prompt expansion adds the mode string to the last line of a multi-line + prompt (one with embedded newlines). + +e. There is a new bindable variable, `colored-completion-prefix', which, if + set, causes the common prefix of a set of possible completions to be + displayed in color. + +f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs- + mode yank-pop. + +g. The redisplay code underwent several efficiency improvements for multibyte + locales. + +h. The insert-char function attempts to batch-insert all pending typeahead + that maps to self-insert, as long as it is coming from the terminal. + +i. rl_callback_sigcleanup: a new application function that can clean up and + unset any state set by readline's callback mode. Intended to be used + after a signal. + +j. If an incremental search string has its last character removed with DEL, the + resulting empty search string no longer matches the previous line. + +k. If readline reads a history file that begins with `#' (or the value of + the history comment character) and has enabled history timestamps, the history + entries are assumed to be delimited by timestamps. This allows multi-line + history entries. + +l. Readline now throws an error if it parses a key binding without a terminating + `:' or whitespace. + +m. The default binding for ^W in vi mode now uses word boundaries specified + by Posix (vi-unix-word-rubout is bindable command name). + +n. rl_clear_visible_line: new application-callable function; clears all + screen lines occupied by the current visible readline line. + +o. rl_tty_set_echoing: application-callable function that controls whether + or not readline thinks it is echoing terminal output. + +p. Handle >| and strings of digits preceding and following redirection + specifications as single tokens when tokenizing the line for history + expansion. + +q. Fixed a bug with displaying completions when the prefix display length + is greater than the length of the completions to be displayed. + +r. The :p history modifier now applies to the entire line, so any expansion + specifying :p causes the line to be printed instead of expanded. + +s. New application-callable function: rl_pending_signal(): returns the signal + number of any signal readline has caught but not yet handled. + +t. New application-settable variable: rl_persistent_signal_handlers: if set + to a non-zero value, readline will enable the readline-6.2 signal handler + behavior in callback mode: handlers are installed when + rl_callback_handler_install is called and removed removed when a complete + line has been read. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to readline-6.3 since +the release of readline-6.2. + +New Features in Readline + +a. Readline is now more responsive to SIGHUP and other fatal signals when + reading input from the terminal or performing word completion but no + longer attempts to run any not-allowable functions from a signal handler + context. + +b. There are new bindable commands to search the history for the string of + characters between the beginning of the line and the point + (history-substring-search-forward, history-substring-search-backward) + +c. Readline allows quoted strings as the values of variables when setting + them with `set'. As a side effect, trailing spaces and tabs are ignored + when setting a string variable's value. + +d. The history library creates a backup of the history file when writing it + and restores the backup on a write error. + +e. New application-settable variable: rl_filename_stat_hook: a function called + with a filename before using it in a call to stat(2). Bash uses it to + expand shell variables so things like $HOME/Downloads have a slash + appended. + +f. New bindable function `print-last-kbd-macro', prints the most-recently- + defined keyboard macro in a reusable format. + +g. New user-settable variable `colored-stats', enables use of colored text + to denote file types when displaying possible completions (colored analog + of visible-stats). + +h. New user-settable variable `keyseq-timout', acts as an inter-character + timeout when reading input or incremental search strings. + +i. New application-callable function: rl_clear_history. Clears the history list + and frees all readline-associated private data. + +j. New user-settable variable, show-mode-in-prompt, adds a characters to the + beginning of the prompt indicating the current editing mode. + +k. New application-settable variable: rl_input_available_hook; function to be + called when readline detects there is data available on its input file + descriptor. + +l. Readline calls an application-set event hook (rl_event_hook) after it gets + a signal while reading input (read returns -1/EINTR but readline does not + handle the signal immediately) to allow the application to handle or + otherwise note it. + +m. If the user-settable variable `history-size' is set to a value less than + 0, the history list size is unlimited. + +n. New application-settable variable: rl_signal_event_hook; function that is + called when readline is reading terminal input and read(2) is interrupted + by a signal. Currently not called for SIGHUP or SIGTERM. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to readline-6.1 since +the release of readline-6.0. + +New Features in Readline + +a. New bindable function: menu-complete-backward. + +b. In the vi insertion keymap, C-n is now bound to menu-complete by default, + and C-p to menu-complete-backward. + +c. When in vi command mode, repeatedly hitting ESC now does nothing, even + when ESC introduces a bound key sequence. This is closer to how + historical vi behaves. + +d. New bindable function: skip-csi-sequence. Can be used as a default to + consume key sequences generated by keys like Home and End without having + to bind all keys. + +e. New application-settable function: rl_filename_rewrite_hook. Can be used + to rewite or modify filenames read from the file system before they are + compared to the word to be completed. + +f. New bindable variable: skip-completed-text, active when completing in the + middle of a word. If enabled, it means that characters in the completion + that match characters in the remainder of the word are "skipped" rather + than inserted into the line. + +g. The pre-readline-6.0 version of menu completion is available as + "old-menu-complete" for users who do not like the readline-6.0 version. + +h. New bindable variable: echo-control-characters. If enabled, and the + tty ECHOCTL bit is set, controls the echoing of characters corresponding + to keyboard-generated signals. + +i. New bindable variable: enable-meta-key. Controls whether or not readline + sends the smm/rmm sequences if the terminal indicates it has a meta key + that enables eight-bit characters. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to readline-6.0 since +the release of readline-5.2. + +New Features in Readline + +a. A new variable, rl_sort_completion_matches; allows applications to inhibit + match list sorting (but beware: some things don't work right if + applications do this). + +b. A new variable, rl_completion_invoking_key; allows applications to discover + the key that invoked rl_complete or rl_menu_complete. + +c. The functions rl_block_sigint and rl_release_sigint are now public and + available to calling applications who want to protect critical sections + (like redisplay). + +d. The functions rl_save_state and rl_restore_state are now public and + available to calling applications; documented rest of readline's state + flag values. + +e. A new user-settable variable, `history-size', allows setting the maximum + number of entries in the history list. + +f. There is a new implementation of menu completion, with several improvements + over the old; the most notable improvement is a better `completions + browsing' mode. + +g. The menu completion code now uses the rl_menu_completion_entry_function + variable, allowing applications to provide their own menu completion + generators. + +h. There is support for replacing a prefix of a pathname with a `...' when + displaying possible completions. This is controllable by setting the + `completion-prefix-display-length' variable. Matches with a common prefix + longer than this value have the common prefix replaced with `...'. + +i. There is a new `revert-all-at-newline' variable.

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 as published by the Free Software +Foundation, version 3 of the License. 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. If you don't want +to install any created shared libraries, run `make install-static'. + +Documentation +============= + +The documentation for the Readline and History libraries appears in +the `doc' subdirectory. There are three texinfo files and a +Unix-style manual page describing the facilities available in the +Readline library. The texinfo files include both user and +programmer's manuals. HTML versions of the manuals appear in the +`doc' subdirectory as well. + +Usage +===== + +Our position on the use of Readline through a shared-library linking +mechanism is that there is no legal difference between shared-library +linking and static linking--either kind of linking combines various +modules into a single larger work. The conditions for using Readline +in a larger work are stated in section 3 of the GNU GPL. + +Reporting Bugs +============== + +Bug reports for Readline should be sent to: + + bug-readline@gnu.org + +When reporting a bug, please include the following information: + + * the version number and release status of Readline (e.g., 4.2-release) + * the machine and OS that it is running on + * a list of the compilation flags or the contents of `config.h', if + appropriate + * a description of the bug + * a recipe for recreating the bug reliably + * a fix for the bug if you have one! + +If you would like to contact the Readline maintainer directly, send mail +to bash-maintainers@gnu.org. + +Since Readline is developed along with bash, the bug-bash@gnu.org mailing +list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains +Readline bug reports and fixes. + +Chet Ramey +chet.ramey@case.edu diff --git a/readline/readline/USAGE b/readline/readline/USAGE new file mode 100644 index 00000000000..edc9f5417d4 --- /dev/null +++ b/readline/readline/USAGE @@ -0,0 +1,37 @@ +From rms@gnu.org Thu Jul 22 20:37:55 1999 +Flags: 10 +Return-Path: rms@gnu.org +Received: from arthur.INS.CWRU.Edu (root@arthur.INS.CWRU.Edu [129.22.8.215]) by odin.INS.CWRU.Edu with ESMTP (8.8.6+cwru/CWRU-2.4-ins) + id UAA25349; Thu, 22 Jul 1999 20:37:54 -0400 (EDT) (from rms@gnu.org for <chet@odin.INS.CWRU.Edu>) +Received: from nike.ins.cwru.edu (root@nike.INS.CWRU.Edu [129.22.8.219]) by arthur.INS.CWRU.Edu with ESMTP (8.8.8+cwru/CWRU-3.6) + id UAA05311; Thu, 22 Jul 1999 20:37:51 -0400 (EDT) (from rms@gnu.org for <chet@po.cwru.edu>) +Received: from pele.santafe.edu (pele.santafe.edu [192.12.12.119]) by nike.ins.cwru.edu with ESMTP (8.8.7/CWRU-2.5-bsdi) + id UAA13350; Thu, 22 Jul 1999 20:37:50 -0400 (EDT) (from rms@gnu.org for <chet@nike.ins.cwru.edu>) +Received: from wijiji.santafe.edu (wijiji [192.12.12.5]) + by pele.santafe.edu (8.9.1/8.9.1) with ESMTP id SAA10831 + for <chet@nike.ins.cwru.edu>; Thu, 22 Jul 1999 18:37:47 -0600 (MDT) +Received: (from rms@localhost) + by wijiji.santafe.edu (8.9.1b+Sun/8.9.1) id SAA01089; + Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Date: Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Message-Id: <199907230037.SAA01089@wijiji.santafe.edu> +X-Authentication-Warning: wijiji.santafe.edu: rms set sender to rms@gnu.org using -f +From: Richard Stallman <rms@gnu.org> +To: chet@nike.ins.cwru.edu +Subject: Use of Readline +Reply-to: rms@gnu.org + +I think Allbery's suggestion is a good one.

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 $(top_builddir)/intl/libintl.a will be created. +dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext +dnl implementations (in libc or libintl) without the ngettext() function +dnl will be ignored. If NEEDSYMBOL is specified and is +dnl 'need-formatstring-macros', then GNU gettext implementations that don't +dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. +dnl INTLDIR is used to find the intl libraries. If empty, +dnl the value `$(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.

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. Examples +of transparent image formats include @acronym{PNG}, @acronym{XCF} and +@acronym{JPG}. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, @acronym{SGML} or +@acronym{XML} for which the @acronym{DTD} and/or processing tools are +not generally available, and the machine-generated @acronym{HTML}, +PostScript or @acronym{PDF} produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +The ``publisher'' means any person or entity that distributes copies +of the Document to the public. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation 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. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy's public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. + +@item +RELICENSING + +``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server.

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. +Unless the reference is absolute, events are relative to the current +position 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 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 +preceding the current position in the history list +starting with +.IR string . +.TP +.B !?\fIstring\fR\fB[?]\fR +Refer to the most recent command +preceding the current position in the history list +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 word. This is usually the last argument, but will expand to the +zeroth word if there is only one word in the line. +.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 <readline/history.h> +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. A history entry is +declared as follows: +.PP +.Vb "typedef void *" histdata_t; +.PP +.nf +typedef struct _hist_entry { + char *line; + char *timestamp; + histdata_t data; +} HIST_ENTRY; +.fi +.PP +The history list itself might therefore be declared as +.PP +.Vb "HIST_ENTRY **" the_history_list; +.PP +The state of the History library is encapsulated into a single structure: +.PP +.nf +/* + * A structure used to pass around the current state of the history. + */ +typedef struct _hist_state { + HIST_ENTRY **entries; /* Pointer to the entries themselves. */ + int offset; /* The location pointer within this array. */ + int length; /* Number of elements within this array. */ + int size; /* Number of slots allocated to this array. */ + int flags; +} HISTORY_STATE; +.fi +.PP +If the flags member includes \fBHS_STIFLED\fP, the history has been +stifled. +.SH "History Functions" +.PP +This section describes the calling sequence for the various functions +exported by the GNU History library. +.SS Initializing History and State Management +This section describes functions used to initialize and manage +the state of the History library when you want to use the history +functions in your program. + +.Fn1 void using_history void +Begin a session in which the history functions might be used. This +initializes the interactive variables. + +.Fn1 "HISTORY_STATE *" history_get_history_state void +Return a structure describing the current state of the input history. + +.Fn1 void history_set_history_state "HISTORY_STATE *state" +Set the state of the history list according to \fIstate\fP. + +.SS History List Management + +These functions manage individual entries on the history list, or set +parameters managing the list itself. + +.Fn1 void add_history "const char *string" +Place \fIstring\fP at the end of the history list. The associated data +field (if any) is set to \fBNULL\fP. +If the maximum number of history entries has been set using +\fBstifle_history()\fP, and the new number of history entries would exceed +that maximum, the oldest history entry is removed. + +.Fn1 void add_history_time "const char *string" +Change the time stamp associated with the most recent history entry to +\fIstring\fP. + +.Fn1 "HIST_ENTRY *" remove_history "int which" +Remove history entry at offset \fIwhich\fP from the history.

The @sc{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. + +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 @dfn{expansion} function +is available which provides for a consistent user interface across +different programs. + +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 similar to +the history substitution provided by @code{csh}. + +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. + +Before declaring any functions using any functionality the History +library provides in other code, an application writer should include +the file @code{<readline/history.h>} 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. + +@node History Storage +@section History Storage + +The history list is an array of history entries.

The @env{HISTCONTROL} and @env{HISTIGNORE} +variables may be set to cause the shell to save only a subset of the +commands entered. +The @code{cmdhist} +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The @code{lithist} +shell option causes the shell to save the command with embedded newlines +instead of semicolons. +The @code{shopt} builtin is used to set these options. +@xref{The Shopt Builtin}, for a description of @code{shopt}. + +@node Bash History Builtins +@section Bash History Builtins +@cindex history builtins + +Bash provides two builtin commands which manipulate the +history list and history file. + +@table @code + +@item fc +@btindex fc +@example +@code{fc [-e @var{ename}] [-lnr] [@var{first}] [@var{last}]} +@code{fc -s [@var{pat}=@var{rep}] [@var{command}]} +@end example + +The first form selects a range of commands from @var{first} to +@var{last} from the history list and displays or edits and re-executes +them. +Both @var{first} and +@var{last} may be specified as a string (to locate the most recent +command beginning with that string) or as a number (an index into the +history list, where a negative number is used as an offset from the +current command number). If @var{last} is not specified, it is set to +@var{first}. If @var{first} is not specified, it is set to the previous +command for editing and @minus{}16 for listing. If the @option{-l} flag is +given, the commands are listed on standard output. The @option{-n} flag +suppresses the command numbers when listing. The @option{-r} flag +reverses the order of the listing. Otherwise, the editor given by +@var{ename} is invoked on a file containing those commands. If +@var{ename} is not given, the value of the following variable expansion +is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.

This section +describes the syntax used to manipulate the history information. + +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. + +@ifset BashFeatures +History expansion is performed immediately after a complete line +is read, before the shell breaks it into words, and is performed +on each line individually. Bash attempts to inform the history +expansion functions about quoting still in effect from previous lines. +@end ifset + +History expansion takes place in two parts. The first is to determine +which line from the history list should be used during substitution. +The second is to select portions of that line for inclusion into the +current one. The line selected from the history is called the +@dfn{event}, and the portions of that line that are acted upon are +called @dfn{words}. Various @dfn{modifiers} are available to manipulate +the selected words. The line is broken into words in the same fashion +that Bash does, so that several words +surrounded by quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is @samp{!} by default. + +History expansion implements shell-like quoting conventions: +a backslash can be used to remove the special handling for the next character; +single quotes enclose verbatim sequences of characters, and can be used to +inhibit history expansion; +and characters enclosed within double quotes may be subject to history +expansion, since backslash can escape the history expansion character, +but single quotes may not, since they are not treated specially within +double quotes. + +@ifset BashFeatures +When using the shell, only @samp{\} and @samp{'} may be used to escape the +history expansion character, but the history expansion character is +also treated as quoted if it immediately precedes the closing double quote +in a double-quoted string. +@end ifset + +@ifset BashFeatures +Several shell options settable with the @code{shopt} +builtin (@pxref{The Shopt Builtin}) may be used to tailor +the behavior of history expansion. If the +@code{histverify} shell option is enabled, and Readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the Readline +editing buffer for further modification. +If Readline is being used, and the @code{histreedit} +shell option is enabled, a failed history expansion will be +reloaded into the Readline editing buffer for correction. +The @option{-p} option to the @code{history} builtin command +may be used to see what a history expansion will do before using it. +The @option{-s} option to the @code{history} builtin may be used to +add commands to the end of the history list without actually executing +them, so that they are available for subsequent recall. +This is most useful in conjunction with Readline. + +The shell allows control of the various characters used by the +history expansion mechanism with the @code{histchars} variable, +as explained above (@pxref{Bash Variables}).

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 +below. +.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. Some GNU Emacs style key escapes can be +used, as in the following example, but the symbolic character names +are not recognized. +.sp +.RS +"\eC\-u": universal\-argument +.br +"\eC\-x\eC\-r": re\-read\-init\-file +.br +"\ee[11~": "Function Key 1" +.RE +.PP +In this example, +.I C-u +is again bound to the function +.BR universal\-argument . +.I "C-x C-r" +is bound to the function +.BR re\-read\-init\-file , +and +.I "ESC [ 1 1 ~" +is bound to insert the text +.if t \f(CWFunction Key 1\fP. +.if n ``Function Key 1''. +.PP +The full set of GNU Emacs style escape sequences available when specifying +key sequences is +.RS +.PD 0 +.TP +.B \eC\- +control prefix +.TP +.B \eM\- +meta prefix +.TP +.B \ee +an escape character +.TP +.B \e\e +backslash +.TP +.B \e" +literal ", a double quote +.TP +.B \e' +literal ', a single quote +.RE +.PD +.PP +In addition to the GNU Emacs style escape sequences, a second +set of backslash escapes is available: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ed +delete +.TP +.B \ef +form feed +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.RE +.PD +.PP +When entering the text of a macro, single or double quotes should +be used to indicate a macro definition. Unquoted text +is assumed to be a function name. +In the macro body, the backslash escapes described above are expanded. +Backslash will quote any other character in the macro text, +including " and '. +.PP +.B Bash +allows the current readline key bindings to be displayed or modified +with the +.B bind +builtin command. The editing mode may be switched during interactive +use by using the +.B \-o +option to the +.B set +builtin command. Other programs using this library provide +similar mechanisms. 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 (the default), readline attempts to bind the control +characters treated specially by the kernel's terminal driver to their +readline equivalents. +.TP +.B blink\-matching\-paren (Off) +If set to \fBOn\fP, readline attempts to briefly move the cursor to an +opening parenthesis when a closing parenthesis is inserted. +.TP +.B colored\-completion\-prefix (Off) +If set to \fBOn\fP, when listing completions, readline displays the +common prefix of the set of possible completions using a different color. +The color definitions are taken from the value of the \fBLS_COLORS\fP +environment variable. +.TP +.B colored\-stats (Off) +If set to \fBOn\fP, readline displays possible completions using different +colors to indicate their file type. +The color definitions are taken from the value of the \fBLS_COLORS\fP +environment variable. +.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\-display\-width (\-1) +The number of screen columns used to display possible matches +when performing completion. +The value is ignored if it is less than 0 or greater than the terminal +screen width. +A value of 0 will cause matches to be displayed one per line. +The default value is \-1. +.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\-map\-case (Off) +If set to \fBOn\fP, and \fBcompletion\-ignore\-case\fP is enabled, readline +treats hyphens (\fI\-\fP) and underscores (\fI_\fP) as equivalent when +performing case\-insensitive filename matching and completion. +.TP +.B completion\-prefix\-display\-length (0) +The length in characters of the common prefix of a list of possible +completions that is displayed without modification. When set to a +value greater than zero, common prefixes longer than this value are +replaced with an ellipsis when displaying possible completions. +.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). +The default is \fIOn\fP, but readline will set it to \fIOff\fP if the +locale contains eight-bit characters. +.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 echo\-control\-characters (On) +When set to \fBOn\fP, on operating systems that indicate they support it, +readline echoes a character corresponding to a signal generated from the +keyboard. +.TP +.B editing\-mode (emacs) +Controls whether readline begins with a set of key bindings similar +to \fIEmacs\fP or \fIvi\fP. +.B editing\-mode +can be set to either +.B emacs +or +.BR vi . +.TP +.B emacs\-mode\-string (@) +If the \fIshow\-mode\-in\-prompt\fP variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when emacs editing mode is active. The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the \e1 and \e2 escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +.TP +.B enable\-bracketed\-paste (Off) +When set to \fBOn\fP, readline will configure the terminal in a way +that will enable it to insert each paste into the editing buffer as a +single string of characters, instead of treating each character as if +it had been read from the keyboard. This can prevent pasted characters +from being interpreted as editing commands. +.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 enable\-meta\-key (On) +When set to \fBOn\fP, readline will try to enable any meta modifier +key the terminal claims to support when it is called. On many terminals, +the meta key is used to send eight-bit characters. +.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 history\-size (unset) +Set the maximum number of history entries saved in the history list. +If set to zero, any existing history entries are deleted and no new entries +are saved. +If set to a value less than zero, the number of history entries is not +limited. +By default, the number of history entries is not limited. +If an attempt is made to set \fIhistory\-size\fP to a non-numeric value, +the maximum number of history entries will be set to 500. +.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. +The default is \fIOff\fP, but readline will set it to \fIOn\fP if the +locale contains eight-bit characters. +.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 keyseq\-timeout (500) +Specifies the duration \fIreadline\fP will wait for a character when reading an +ambiguous key sequence (one that can form a complete key sequence using +the input read so far, or can take additional input to complete a longer +key sequence). +If no input is received within the timeout, \fIreadline\fP will use the shorter +but complete key sequence. +The value is specified in milliseconds, so a value of 1000 means that +\fIreadline\fP will wait one second for additional input. +If this variable is set to a value less than or equal to zero, or to a +non-numeric value, \fIreadline\fP will wait until another key is pressed to +decide which key sequence to complete. +.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. +If set to \fBOff\fP, the leading `.' must be +supplied by the user in the filename to be completed. +.TP +.B menu\-complete\-display\-prefix (Off) +If set to \fBOn\fP, menu completion displays the common prefix of the +list of possible completions (which may be empty) before cycling through +the list. +.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. +The default is \fIOff\fP, but readline will set it to \fIOn\fP if the +locale contains eight-bit characters. +.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 revert\-all\-at\-newline (Off) +If set to \fBOn\fP, readline will undo all changes to history lines +before returning when \fBaccept\-line\fP is executed. By default, +history lines may be modified and retain individual undo lists across +calls to \fBreadline\fP. +.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 show\-mode\-in\-prompt (Off) +If set to \fBOn\fP, add a string to the beginning of the prompt +indicating the editing mode: emacs, vi command, or vi insertion. +The mode strings are user-settable (e.g., \fIemacs\-mode\-string\fP). +.TP +.B skip\-completed\-text (Off) +If set to \fBOn\fP, this alters the default completion behavior when +inserting a single match into the line. It's only active when +performing completion in the middle of a word. If enabled, readline +does not insert characters from the completion that match characters +after point in the word being completed, so portions of the word +following the cursor are not duplicated. +.TP +.B vi\-cmd\-mode\-string ((cmd)) +If the \fIshow\-mode\-in\-prompt\fP variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in command mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the \e1 and \e2 escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +.TP +.B vi\-ins\-mode\-string ((ins)) +If the \fIshow\-mode\-in\-prompt\fP variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in insertion mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the \e1 and \e2 escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +.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 $if +construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +readline. The text of the test, after any comparison operator, +extends to the end of the line; +unless otherwise noted, no characters are required to isolate it. +.RS +.IP \fBmode\fP +The \fBmode=\fP form of the \fB$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 \fBversion\fP +The \fBversion\fP test may be used to perform comparisons against +specific readline versions. +The \fBversion\fP expands to the current readline version. +The set of comparison operators includes +.BR = , +(and +.BR == ), +.BR != , +.BR <= , +.BR >= , +.BR < , +and +.BR > . +The version number supplied on the right side of the operator consists +of a major version number, an optional decimal point, and an optional +minor version (e.g., \fB7.1\fP). If the minor version is omitted, it +is assumed to be \fB0\fP. +The operator may be separated from the string \fBversion\fP +and from the version number argument by whitespace. +.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 \fBbash\fP: +.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 +.IP \fIvariable\fP +The \fIvariable\fP construct provides simple equality tests for readline +variables and values. +The permitted comparison operators are \fI=\fP, \fI==\fP, and \fI!=\fP. +The variable name must be separated from the comparison operator by +whitespace; the operator may be separated from the value on the right hand +side by whitespace. +Both string and boolean variables may be tested. Boolean variables must be +tested against the values \fIon\fP and \fIoff\fP. +.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.

This will not have the desired effect if the current +Readline line does not take up more than one physical line or if point is not +greater than the length of the prompt plus the screen width. +.TP +.B next\-screen\-line +Attempt to move point to the same physical screen column on the next +physical screen line. This will not have the desired effect if the current +Readline line does not take up more than one physical line or if the length +of the current Readline line is not greater than the length of the prompt +plus the screen width. +.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.

For such programs, the default behaviour of +Readline is sufficient. 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. + +Readline performs some expansion on the @var{prompt} before it is +displayed on the screen. See the description of @code{rl_expand_prompt} +(@pxref{Redisplay}) for additional details, especially if @var{prompt} +will contain characters that do not consume physical screen space when +displayed. + +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{<readline/readline.h>} +in any file that uses Readline's features.

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{SIGHUP}, +@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. + +When an application is using the callback interface +(@pxref{Alternate Interface}), Readline installs signal handlers only for +the duration of the call to @code{rl_callback_read_char}. Applications +using the callback interface should be prepared to clean up Readline's +state if they wish to handle the signal before the line handler completes +and restores the terminal state. + +If an application using the callback interface wishes to have Readline +install its signal handlers at the time the application calls +@code{rl_callback_handler_install} and remove them only when a complete +line of input has been read, it should set the +@code{rl_persistent_signal_handlers} variable to a non-zero value. +This allows an application to defer all of the handling of the signals +Readline catches to Readline. +Applications should use this variable with care; it can result in Readline +catching signals and not acting on them (or allowing the application to react +to them) until the application calls @code{rl_callback_read_char}. This +can result in an application becoming less responsive to keyboard signals +like SIGINT. +If an application does not want or need to perform any signal handling, or +does not need to do any processing between calls to @code{rl_callback_read_char}, +setting this variable may be desirable. + +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.

If your program is one of these, then +it can provide completion for commands, data, or both. +The following sections describe how your program and Readline +cooperate to provide this service. + +@menu +* How Completing Works:: The logic used to do completion. +* Completion Functions:: Functions provided by Readline. +* Completion Variables:: Variables which control completion. +* A Short Completion Example:: An example of writing completer subroutines. +@end menu + +@node How Completing Works +@subsection How Completing Works + +In order to complete some text, the full list of possible completions +must be available. 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 have supplied the function +that does the initial simple matching selection algorithm (see +@code{rl_completion_matches()}). The default is to do filename completion. +@end deftypefun + +@deftypevar {rl_compentry_func_t *} rl_completion_entry_function +This is a pointer to the generator function for +@code{rl_completion_matches()}. +If the value of @code{rl_completion_entry_function} is +@code{NULL} then the default filename generator +function, @code{rl_filename_completion_function()}, is used. +An @dfn{application-specific completion function} is a function whose +address is assigned to @code{rl_completion_entry_function} and whose +return values are used to generate possible completions. +@end deftypevar + +@node Completion Functions +@subsection Completion Functions + +Here is the complete list of callable completion functions present in +Readline. + +@deftypefun int rl_complete_internal (int what_to_do) +Complete the word at or before point. @var{what_to_do} says what to do +with the completion. A value of @samp{?} means list the possible +completions. @samp{TAB} means do standard completion. @samp{*} means +insert all of the possible completions. @samp{!} means to display +all of the possible completions, if there is more than one, as well as +performing partial completion. @samp{@@} is similar to @samp{!}, but +possible completions are not listed if the possible completions share +a common prefix. +@end deftypefun + +@deftypefun int rl_complete (int ignore, int invoking_key) +Complete the word at or before point. You have supplied the function +that does the initial simple matching selection algorithm (see +@code{rl_completion_matches()} and @code{rl_completion_entry_function}). +The default is to do filename +completion. This calls @code{rl_complete_internal()} with an +argument depending on @var{invoking_key}. +@end deftypefun + +@deftypefun int rl_possible_completions (int count, int invoking_key) +List the possible completions. See description of @code{rl_complete +()}. This calls @code{rl_complete_internal()} with an argument of +@samp{?}. +@end deftypefun + +@deftypefun int rl_insert_completions (int count, int invoking_key) +Insert the list of possible completions into the line, deleting the +partially-completed word. See description of @code{rl_complete()}. +This calls @code{rl_complete_internal()} with an argument of @samp{*}. +@end deftypefun + +@deftypefun int rl_completion_mode (rl_command_func_t *cfunc) +Returns the appropriate value to pass to @code{rl_complete_internal()} +depending on whether @var{cfunc} was called twice in succession and +the values of the @code{show-all-if-ambiguous} and +@code{show-all-if-unmodified} variables. +Application-specific completion functions may use this function to present +the same interface as @code{rl_complete()}. +@end deftypefun + +@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func) +Returns an array of strings which is a list of completions for +@var{text}. If there are no completions, returns @code{NULL}. +The first entry in the returned array is the substitution for @var{text}. +The remaining entries are the possible completions. The array is +terminated with a @code{NULL} pointer. + +@var{entry_func} is a function of two args, and returns a +@code{char *}. The first argument is @var{text}. The second is a +state argument; it is zero on the first call, and non-zero on subsequent +calls. @var{entry_func} returns a @code{NULL} pointer to the caller +when there are no more matches. +@end deftypefun + +@deftypefun {char *} rl_filename_completion_function (const char *text, int state) +A generator function for filename completion in the general case. +@var{text} is a partial filename. +The Bash source is a useful reference for writing application-specific +completion functions (the Bash completion functions call this and other +Readline functions). +@end deftypefun + +@deftypefun {char *} rl_username_completion_function (const char *text, int state) +A completion generator for usernames. @var{text} contains a partial +username preceded by a random character (usually @samp{~}).

This is called if filename completion is being +attempted and one of the characters in @code{rl_filename_quote_characters} +appears in a completed filename. The function is called with +@var{text}, @var{match_type}, and @var{quote_pointer}. The @var{text} +is the filename to be quoted. The @var{match_type} is either +@code{SINGLE_MATCH}, if there is only one completion match, or +@code{MULT_MATCH}. Some functions use this to decide whether or not to +insert a closing quote character. The @var{quote_pointer} is a pointer +to any opening quote character the user typed. Some functions choose +to reset this character. +@end deftypevar + +@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function +A pointer to a function that will remove application-specific quoting +characters from a filename before completion is attempted, so those +characters do not interfere with matching the text against names in +the filesystem. It is called with @var{text}, the text of the word +to be dequoted, and @var{quote_char}, which is the quoting character +that delimits the filename (usually @samp{'} or @samp{"}). If +@var{quote_char} is zero, the filename was not in an embedded string. +@end deftypevar + +@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p +A pointer to a function to call that determines whether or not a specific +character in the line buffer is quoted, according to whatever quoting +mechanism the program calling Readline uses. The function is called with +two arguments: @var{text}, the text of the line, and @var{index}, the +index of the character in the line. It is used to decide whether a +character found in @code{rl_completer_word_break_characters} should be +used to break words for the completer. +@end deftypevar + +@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function +This function, if defined, is called by the completer when real filename +completion is done, after all the matching names have been generated. +It is passed a @code{NULL} terminated array of matches. +The first element (@code{matches[0]}) is the +maximal substring common to all matches. This function can +re-arrange the list of matches as required, but each element deleted +from the array must be freed. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook +This function, if defined, is allowed to modify the directory portion +of filenames Readline completes. +It could be used to expand symbolic links or shell variables in pathnames. +It is called with the address of a string (the current directory name) as an +argument, and may modify that string. +If the string is replaced with a new string, the old value should be freed. +Any modified directory name should have a trailing slash. +The modified value will be used as part of the completion, replacing +the directory portion of the pathname the user typed. +At the least, even if no other expansion is performed, this function should +remove any quote characters from the directory name, because its result will +be passed directly to @code{opendir()}. + +The directory completion hook returns an integer that should be non-zero if +the function modifies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_directory_rewrite_hook; +If non-zero, this is the address of a function to call when completing +a directory name.

It is +called before rl_directory_completion_hook. +At the least, even if no other expansion is performed, this function should +remove any quote characters from the directory name, because its result will +be passed directly to @code{opendir()}. + +The directory rewrite hook returns an integer that should be non-zero if +the function modfies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_icppfunc_t *} rl_filename_stat_hook +If non-zero, this is the address of a function for the completer to +call before deciding which character to append to a completed name. +This function modifies its filename name argument, and the modified value +is passed to @code{stat()} to determine the file's type and characteristics. +This function does not need to remove quote characters from the filename. + +The stat hook returns an integer that should be non-zero if +the function modfies its directory argument. +The function should not modify the directory argument if it returns 0. +@end deftypevar + +@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook +If non-zero, this is the address of a function called when reading +directory entries from the filesystem for completion and comparing +them to the partial word to be completed. The function should +perform any necessary application or system-specific conversion on +the filename, such as converting between character sets or converting +from a filesystem format to a character input format. +The function takes two arguments: @var{fname}, the filename to be converted, +and @var{fnlen}, its length in bytes. +It must either return its first argument (if no conversion takes place) +or the converted filename in newly-allocated memory. The converted +form is used to compare against the word to be completed, and, if it +matches, is added to the list of matches. Readline will free the +allocated string. +@end deftypevar + +@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook +If non-zero, then this is the address of a function to call when +completing a word would normally display the list of possible matches. +This function is called in lieu of Readline displaying the list. +It takes three arguments: +(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length}) +where @var{matches} is the array of matching strings, +@var{num_matches} is the number of strings in that array, and +@var{max_length} is the length of the longest string in that array. +Readline provides a convenience function, @code{rl_display_match_list}, +that takes care of doing the display to Readline's output stream. +You may call that function from this hook. +@end deftypevar + +@deftypevar {const char *} rl_basic_word_break_characters +The basic list of characters that signal a break between words for the +completer routine.

It should return +a character string like @code{rl_completer_word_break_characters} to be +used to perform the current completion. The function may choose to set +@code{rl_completer_word_break_characters} itself. If the function +returns @code{NULL}, @code{rl_completer_word_break_characters} is used. +@end deftypevar + +@deftypevar {const char *} rl_completer_quote_characters +A list of characters which can be used to quote a substring of the line. +Completion occurs on the entire substring, and within the substring +@code{rl_completer_word_break_characters} are treated as any other character, +unless they also appear within this list. +@end deftypevar + +@deftypevar {const char *} rl_filename_quote_characters +A list of characters that cause a filename to be quoted by the completer +when they appear in a completed filename. The default is the null string. +@end deftypevar + +@deftypevar {const char *} rl_special_prefixes +The list of characters that are word break characters, but should be +left in @var{text} when it is passed to the completion function. +Programs can use this to help determine what kind of completing to do. +For instance, Bash sets this variable to "$@@" so that it can complete +shell variables and hostnames. +@end deftypevar + +@deftypevar int rl_completion_query_items +Up to this many items will be displayed in response to a +possible-completions call.

Specifically, +@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all +stand for themselves when seen in this text, or in an init file +(@pxref{Readline Init File}). +If your keyboard lacks a @key{LFD} key, typing @key{C-j} will +produce the desired character. +The @key{RET} key may be labeled @key{Return} or @key{Enter} on +some keyboards. + +@node Readline Interaction +@section Readline Interaction +@cindex interaction, readline + +Often during an interactive session you type in a long line of text, +only to notice that the first word on the line is misspelled. The +Readline library gives you a set of commands for manipulating the text +as you type it in, allowing you to just fix your typo, and not forcing +you to retype the majority of the line. Using these editing commands, +you move the cursor to the place that needs correction, and delete or +insert the text of the corrections. Then, when you are satisfied with +the line, you simply press @key{RET}. You do not have to be at the +end of the line to press @key{RET}; the entire line is accepted +regardless of the location of the cursor within the line. + +@menu +* Readline Bare Essentials:: The least you need to know about Readline. +* Readline Movement Commands:: Moving about the input line. +* Readline Killing Commands:: How to delete text, and how to get it back! +* Readline Arguments:: Giving numeric arguments to commands. +* Searching:: Searching through previous lines. +@end menu + +@node Readline Bare Essentials +@subsection Readline Bare Essentials +@cindex notation, readline +@cindex command editing +@cindex editing command lines + +In order to enter characters into the line, simply type them. The typed +character appears where the cursor was, and then the cursor moves one +space to the right. If you mistype a character, you can use your +erase character to back up and delete the mistyped character. + +Sometimes you may mistype a character, and +not notice the error until you have typed several other characters. In +that case, you can type @kbd{C-b} to move the cursor to the left, and then +correct your mistake. Afterwards, you can move the cursor to the right +with @kbd{C-f}. + +When you add text in the middle of a line, you will notice that characters +to the right of the cursor are `pushed over' to make room for the text +that you have inserted. Likewise, when you delete text behind the cursor, +characters to the right of the cursor are `pulled back' to fill in the +blank space created by the removal of the text. A list of the bare +essentials for editing the text of an input line follows. + +@table @asis +@item @kbd{C-b} +Move back one character. +@item @kbd{C-f} +Move forward one character. +@item @key{DEL} or @key{Backspace} +Delete the character to the left of the cursor. +@item @kbd{C-d} +Delete the character underneath the cursor. +@item @w{Printing characters} +Insert the character into the line at the cursor. +@item @kbd{C-_} or @kbd{C-x C-u} +Undo the last editing command. You can undo all the way back to an +empty line. +@end table + +@noindent +(Depending on your configuration, the @key{Backspace} key be set to +delete the character to the left of the cursor and the @key{DEL} key set +to delete the character underneath the cursor, like @kbd{C-d}, rather +than the character to the left of the cursor.) + +@node Readline Movement Commands +@subsection Readline Movement Commands + + +The above table describes the most basic keystrokes that you need +in order to do editing of the input line. For your convenience, many +other commands have been added in addition to @kbd{C-b}, @kbd{C-f}, +@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly +about the line. + +@table @kbd +@item C-a +Move to the start of the line. +@item C-e +Move to the end of the line. +@item M-f +Move forward a word, where a word is composed of letters and digits. +@item M-b +Move backward a word. +@item C-l +Clear the screen, reprinting the current line at the top. +@end table + +Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves +forward a word. It is a loose convention that control keystrokes +operate on characters while meta keystrokes operate on words. + +@node Readline Killing Commands +@subsection Readline Killing Commands + +@cindex killing text +@cindex yanking text + +@dfn{Killing} text means to delete the text from the line, but to save +it away for later use, usually by @dfn{yanking} (re-inserting) +it back into the line. +(`Cut' and `paste' are more recent jargon for `kill' and `yank'.) + +If the description for a command says that it `kills' text, then you can +be sure that you can get the text back in a different (or the same) +place later. + +When you use a kill command, the text is saved in a @dfn{kill-ring}. +Any number of consecutive kills save all of the killed text together, so +that when you yank it back, you get it all. The kill +ring is not line specific; the text that you killed on a previously +typed line is available to be yanked back later, when you are typing +another line. +@cindex kill ring + +Here is the list of commands for killing text. + +@table @kbd +@item C-k +Kill the text from the current cursor position to the end of the line. + +@item M-d +Kill from the cursor to the end of the current word, or, if between +words, to the end of the next word. +Word boundaries are the same as those used by @kbd{M-f}. + +@item M-@key{DEL} +Kill from the cursor the start of the current word, or, if between +words, to the start of the previous word. +Word boundaries are the same as those used by @kbd{M-b}. + +@item C-w +Kill from the cursor to the previous whitespace. This is different than +@kbd{M-@key{DEL}} because the word boundaries differ. + +@end table + +Here is how to @dfn{yank} the text back into the line. Yanking +means to copy the most-recently-killed text from the kill buffer. + +@table @kbd +@item C-y +Yank the most recently killed text back into the buffer at the cursor. + +@item M-y +Rotate the kill-ring, and yank the new top. 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 search string may be +typed by the user or be part of the contents of the current line. + +@node Readline Init File +@section Readline Init File +@cindex initialization file, readline + +Although the Readline library comes with a set of Emacs-like +keybindings installed by default, it is possible to use a different set +of keybindings. +Any user can customize programs that use Readline by putting +commands in an @dfn{inputrc} file, conventionally in his home directory. +The name of this +@ifset BashFeatures +file is taken from the value of the shell variable @env{INPUTRC}. If +@end ifset +@ifclear BashFeatures +file is taken from the value of the environment variable @env{INPUTRC}. If +@end ifclear +that variable is unset, the default is @file{~/.inputrc}. If that +file does not exist or cannot be read, the ultimate default is +@file{/etc/inputrc}. + +When a program which uses the Readline library starts up, the +init file is read, and the key bindings are set. + +In addition, the @code{C-x C-r} command re-reads this init file, thus +incorporating any changes that you might have made to it. + +@menu +* Readline Init File Syntax:: Syntax for the commands in the inputrc file. + +* Conditional Init Constructs:: Conditional key bindings in the inputrc file. + +* Sample Init File:: An example inputrc file. +@end menu + +@node Readline Init File Syntax +@subsection Readline Init File Syntax + +There are only a few basic constructs allowed in the +Readline init file.

The default value +is @code{"#"}. + +@item completion-display-width +@vindex completion-display-width +The number of screen columns used to display possible matches +when performing completion. +The value is ignored if it is less than 0 or greater than the terminal +screen width. +A value of 0 will cause matches to be displayed one per line. +The default value is -1. + +@item completion-ignore-case +@vindex completion-ignore-case +If set to @samp{on}, Readline performs filename matching and completion +in a case-insensitive fashion. +The default value is @samp{off}. + +@item completion-map-case +@vindex completion-map-case +If set to @samp{on}, and @var{completion-ignore-case} is enabled, Readline +treats hyphens (@samp{-}) and underscores (@samp{_}) as equivalent when +performing case-insensitive filename matching and completion. +The default value is @samp{off}. + +@item completion-prefix-display-length +@vindex completion-prefix-display-length +The length in characters of the common prefix of a list of possible +completions that is displayed without modification. When set to a +value greater than zero, common prefixes longer than this value are +replaced with an ellipsis when displaying possible completions. + +@item completion-query-items +@vindex completion-query-items +The number of possible completions that determines when the user is +asked whether the list of possibilities should be displayed. +If the number of possible completions is greater than this value, +Readline will ask the user whether or not he wishes to view +them; otherwise, they are simply listed. +This variable must be set to an integer value greater than or equal to 0. +A negative value means Readline should never ask. +The default limit is @code{100}. + +@item convert-meta +@vindex convert-meta +If set to @samp{on}, Readline will convert characters with the +eighth bit set to an @sc{ascii} key sequence by stripping the eighth +bit and prefixing an @key{ESC} character, converting them to a +meta-prefixed key sequence. The default value is @samp{on}, but +will be set to @samp{off} if the locale is one that contains +eight-bit characters. + +@item disable-completion +@vindex disable-completion +If set to @samp{On}, Readline will inhibit word completion. +Completion characters will be inserted into the line as if they had +been mapped to @code{self-insert}. The default is @samp{off}. + +@item echo-control-characters +@vindex echo-control-characters +When set to @samp{on}, on operating systems that indicate they support it, +readline echoes a character corresponding to a signal generated from the +keyboard. The default is @samp{on}. + +@item editing-mode +@vindex editing-mode +The @code{editing-mode} variable controls which default set of +key bindings is used. By default, Readline starts up in Emacs editing +mode, where the keystrokes are most similar to Emacs. This variable can be +set to either @samp{emacs} or @samp{vi}. + +@item emacs-mode-string +@vindex emacs-mode-string +If the @var{show-mode-in-prompt} variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when emacs editing mode is active. The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{@@}. + +@item enable-bracketed-paste +@vindex enable-bracketed-paste +When set to @samp{On}, Readline will configure the terminal in a way +that will enable it to insert each paste into the editing buffer as a +single string of characters, instead of treating each character as if +it had been read from the keyboard. This can prevent pasted characters +from being interpreted as editing commands. The default is @samp{off}. + +@item enable-keypad +@vindex enable-keypad +When set to @samp{on}, Readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. The default is @samp{off}. + +@item enable-meta-key +When set to @samp{on}, Readline will try to enable any meta modifier +key the terminal claims to support when it is called. On many terminals, +the meta key is used to send eight-bit characters. +The default is @samp{on}. + +@item expand-tilde +@vindex expand-tilde +If set to @samp{on}, tilde expansion is performed when Readline +attempts word completion. The default is @samp{off}. + +@item history-preserve-point +@vindex history-preserve-point +If set to @samp{on}, the history code attempts to place the point (the +current cursor position) at the +same location on each history line retrieved with @code{previous-history} +or @code{next-history}. The default is @samp{off}. + +@item history-size +@vindex history-size +Set the maximum number of history entries saved in the history list. +If set to zero, any existing history entries are deleted and no new entries +are saved. +If set to a value less than zero, the number of history entries is not +limited. +By default, the number of history entries is not limited. +If an attempt is made to set @var{history-size} to a non-numeric value, +the maximum number of history entries will be set to 500. + +@item horizontal-scroll-mode +@vindex horizontal-scroll-mode +This variable can be set to either @samp{on} or @samp{off}. Setting it +to @samp{on} means that the text of the lines being edited will scroll +horizontally on a single screen line when they are longer than the width +of the screen, instead of wrapping onto a new screen line. By default, +this variable is set to @samp{off}. + +@item input-meta +@vindex input-meta +@vindex meta-flag +If set to @samp{on}, Readline will enable eight-bit input (it +will not clear the eighth bit in the characters it reads), +regardless of what the terminal claims it can support. The +default value is @samp{off}, but Readline will set it to @samp{on} if the +locale contains eight-bit characters. +The name @code{meta-flag} is a synonym for this variable. + +@item isearch-terminators +@vindex isearch-terminators +The string of characters that should terminate an incremental search without +subsequently executing the character as a command (@pxref{Searching}). +If this variable has not been given a value, the characters @key{ESC} and +@kbd{C-J} will terminate an incremental search. + +@item keymap +@vindex keymap +Sets Readline's idea of the current keymap for key binding commands. +Built-in @code{keymap} names are +@code{emacs}, +@code{emacs-standard}, +@code{emacs-meta}, +@code{emacs-ctlx}, +@code{vi}, +@code{vi-move}, +@code{vi-command}, and +@code{vi-insert}. +@code{vi} is equivalent to @code{vi-command} (@code{vi-move} is also a +synonym); @code{emacs} is equivalent to @code{emacs-standard}. +Applications may add additional names. +The default value is @code{emacs}. +The value of the @code{editing-mode} variable also affects the +default keymap. + +@item keyseq-timeout +Specifies the duration Readline will wait for a character when reading an +ambiguous key sequence (one that can form a complete key sequence using +the input read so far, or can take additional input to complete a longer +key sequence). +If no input is received within the timeout, Readline will use the shorter +but complete key sequence. +Readline uses this value to determine whether or not input is +available on the current input source (@code{rl_instream} by default). +The value is specified in milliseconds, so a value of 1000 means that +Readline will wait one second for additional input. +If this variable is set to a value less than or equal to zero, or to a +non-numeric value, Readline will wait until another key is pressed to +decide which key sequence to complete. +The default value is @code{500}. + +@item mark-directories +If set to @samp{on}, completed directory names have a slash +appended. The default is @samp{on}. + +@item mark-modified-lines +@vindex mark-modified-lines +This variable, when set to @samp{on}, causes Readline to display an +asterisk (@samp{*}) at the start of history lines which have been modified. +This variable is @samp{off} by default. + +@item mark-symlinked-directories +@vindex mark-symlinked-directories +If set to @samp{on}, completed names which are symbolic links +to directories have a slash appended (subject to the value of +@code{mark-directories}). +The default is @samp{off}. + +@item match-hidden-files +@vindex match-hidden-files +This variable, when set to @samp{on}, causes Readline to match files whose +names begin with a @samp{.} (hidden files) when performing filename +completion. +If set to @samp{off}, the leading @samp{.} must be +supplied by the user in the filename to be completed. +This variable is @samp{on} by default. + +@item menu-complete-display-prefix +@vindex menu-complete-display-prefix +If set to @samp{on}, menu completion displays the common prefix of the +list of possible completions (which may be empty) before cycling through +the list. The default is @samp{off}. + +@item output-meta +@vindex output-meta +If set to @samp{on}, Readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +The default is @samp{off}, but Readline will set it to @samp{on} if the +locale contains eight-bit characters. + +@item page-completions +@vindex page-completions +If set to @samp{on}, Readline uses an internal @code{more}-like pager +to display a screenful of possible completions at a time. +This variable is @samp{on} by default. + +@item print-completions-horizontally +If set to @samp{on}, Readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +The default is @samp{off}. + +@item revert-all-at-newline +@vindex revert-all-at-newline +If set to @samp{on}, Readline will undo all changes to history lines +before returning when @code{accept-line} is executed. By default, +history lines may be modified and retain individual undo lists across +calls to @code{readline}. The default is @samp{off}. + +@item show-all-if-ambiguous +@vindex show-all-if-ambiguous +This alters the default behavior of the completion functions. If +set to @samp{on}, +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +The default value is @samp{off}. + +@item show-all-if-unmodified +@vindex show-all-if-unmodified +This alters the default behavior of the completion functions in +a fashion similar to @var{show-all-if-ambiguous}. +If set to @samp{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. +The default value is @samp{off}. + +@item show-mode-in-prompt +@vindex show-mode-in-prompt +If set to @samp{on}, add a string to the beginning of the prompt +indicating the editing mode: emacs, vi command, or vi insertion. +The mode strings are user-settable (e.g., @var{emacs-mode-string}). +The default value is @samp{off}. + +@item skip-completed-text +@vindex skip-completed-text +If set to @samp{on}, this alters the default completion behavior when +inserting a single match into the line. It's only active when +performing completion in the middle of a word. If enabled, readline +does not insert characters from the completion that match characters +after point in the word being completed, so portions of the word +following the cursor are not duplicated. +For instance, if this is enabled, attempting completion when the cursor +is after the @samp{e} in @samp{Makefile} will result in @samp{Makefile} +rather than @samp{Makefilefile}, assuming there is a single possible +completion. +The default value is @samp{off}. + +@item vi-cmd-mode-string +@vindex vi-cmd-mode-string +If the @var{show-mode-in-prompt} variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in command mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{(cmd)}. + +@item vi-ins-mode-string +@vindex vi-ins-mode-string +If the @var{show-mode-in-prompt} variable is enabled, +this string is displayed immediately before the last line of the primary +prompt when vi editing mode is active and in insertion mode. +The value is expanded like a +key binding, so the standard set of meta- and control prefixes and +backslash escape sequences is available. +Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of +non-printing characters, which can be used to embed a terminal control +sequence into the mode string. +The default is @samp{(ins)}. + +@item visible-stats +@vindex visible-stats +If set to @samp{on}, a character denoting a file's type +is appended to the filename when listing possible +completions. The default is @samp{off}. + +@end table + +@item Key Bindings +The syntax for controlling key bindings in the init file is +simple. First you need to find the name of the command that you +want to change. The following sections contain tables of the command +name, the default keybinding, if any, and a short description of what +the command does. + +Once you know the name of the command, simply place on a line +in the init file the name of the key +you wish to bind the command to, a colon, and then the name of the +command. +There can be no space between the key name and the colon -- that will be +interpreted as part of the key name. +The name of the key can be expressed in different ways, depending on +what you find most comfortable. + +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a @var{macro}). + +@ifset BashFeatures +The @w{@code{bind -p}} command displays Readline function names and +bindings in a format that can put directly into an initialization file. +@xref{Bash Builtins}. +@end ifset + +@table @asis +@item @w{@var{keyname}: @var{function-name} or @var{macro}} +@var{keyname} is the name of a key spelled out in English. For example: +@example +Control-u: universal-argument +Meta-Rubout: backward-kill-word +Control-o: "> output" +@end example + +In the example above, @kbd{C-u} is bound to the function +@code{universal-argument}, +@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and +@kbd{C-o} is bound to run the macro +expressed on the right hand side (that is, to insert the text +@samp{> output} into the line). + +A number of symbolic character names are recognized while +processing this key binding syntax: +@var{DEL}, +@var{ESC}, +@var{ESCAPE}, +@var{LFD}, +@var{NEWLINE}, +@var{RET}, +@var{RETURN}, +@var{RUBOUT}, +@var{SPACE}, +@var{SPC}, +and +@var{TAB}. + +@item @w{"@var{keyseq}": @var{function-name} or @var{macro}} +@var{keyseq} differs from @var{keyname} above in that strings +denoting an entire key sequence can be specified, by placing +the key sequence in double quotes.

There are four parser directives used. + +@table @code +@item $if +The @code{$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, after any comparison operator, +extends to the end of the line; +unless otherwise noted, no characters are required to isolate it. + +@table @code +@item mode +The @code{mode=} form of the @code{$if} directive is used to test +whether Readline is in @code{emacs} or @code{vi} mode. +This may be used in conjunction +with the @samp{set keymap} command, for instance, to set bindings in +the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if +Readline is starting out in @code{emacs} mode. + +@item term +The @code{term=} form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +@samp{=} is tested against both the full name of the terminal and +the portion of the terminal name before the first @samp{-}. This +allows @code{sun} to match both @code{sun} and @code{sun-cmd}, +for instance. + +@item version +The @code{version} test may be used to perform comparisons against +specific Readline versions. +The @code{version} expands to the current Readline version. +The set of comparison operators includes +@samp{=} (and @samp{==}), @samp{!=}, @samp{<=}, @samp{>=}, @samp{<}, +and @samp{>}. +The version number supplied on the right side of the operator consists +of a major version number, an optional decimal point, and an optional +minor version (e.g., @samp{7.1}). If the minor version is omitted, it +is assumed to be @samp{0}. +The operator may be separated from the string @code{version} and +from the version number argument by whitespace. +The following example sets a variable if the Readline version being used +is 7.0 or newer: +@example +$if version >= 7.0 +set show-mode-in-prompt on +$endif +@end example + +@item application +The @var{application} construct is used to include +application-specific settings. Each program using the Readline +library sets the @var{application name}, and you can test for +a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +@example +$if Bash +# Quote the current or previous word +"\C-xq": "\eb\"\ef\"" +$endif +@end example + +@item variable +The @var{variable} construct provides simple equality tests for Readline +variables and values. +The permitted comparison operators are @samp{=}, @samp{==}, and @samp{!=}. +The variable name must be separated from the comparison operator by +whitespace; the operator may be separated from the value on the right hand +side by whitespace. +Both string and boolean variables may be tested. Boolean variables must be +tested against the values @var{on} and @var{off}. +The following example is equivalent to the @code{mode=emacs} test described +above: +@example +$if editing-mode == emacs +set show-mode-in-prompt on +$endif +@end example +@end table + +@item $endif +This command, as seen in the previous example, terminates an +@code{$if} command. + +@item $else +Commands in this branch of the @code{$if} directive are executed if +the test fails. + +@item $include +This directive takes a single filename as an argument and reads commands +and bindings from that file. +For example, the following directive reads from @file{/etc/inputrc}: +@example +$include /etc/inputrc +@end example +@end table + +@node Sample Init File +@subsection Sample Init File + +Here is an example of an @var{inputrc} file.

the function or command has complete freedom in generating +the matches. + +Any function specified with @option{-F} is invoked first. +The function may use any of the shell facilities, including the +@code{compgen} and @code{compopt} builtins described below +(@pxref{Programmable Completion Builtins}), to generate the matches. +It must put the possible completions in the @env{COMPREPLY} array +variable, one per array element. + +Next, any command specified with the @option{-C} option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to +the standard output. +Backslash may be used to escape a newline, if necessary. + +After all of the possible completions are generated, any filter +specified with the @option{-X} option is applied to the list. +The filter is a pattern as used for pathname expansion; a @samp{&} +in the pattern is replaced with the text of the word being completed. +A literal @samp{&} may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading @samp{!} negates the pattern; in this case any completion +not matching the pattern will be removed. +If the @code{nocasematch} shell option +(see the description of @code{shopt} in @ref{The Shopt Builtin}) +is enabled, the match is performed without regard to the case +of alphabetic characters. + +Finally, any prefix and suffix specified with the @option{-P} and @option{-S} +options are added to each member of the completion list, and the result is +returned to the Readline completion code as the list of possible +completions. + +If the previously-applied actions do not generate any matches, and the +@option{-o dirnames} option was supplied to @code{complete} when the +compspec was defined, directory name completion is attempted. + +If the @option{-o plusdirs} option was supplied to @code{complete} when +the compspec was defined, directory name completion is attempted and any +matches are added to the results of the other actions. + +By default, if a compspec is found, whatever it generates is returned to +the completion code as the full set of possible completions. +The default Bash completions are not attempted, and the Readline default +of filename completion is disabled. +If the @option{-o bashdefault} option was supplied to @code{complete} when +the compspec was defined, the default Bash completions are attempted +if the compspec generates no matches. +If the @option{-o default} option was supplied to @code{complete} when the +compspec was defined, Readline's default completion will be performed +if the compspec (and, if attempted, the default Bash completions) +generate no matches. + +When a compspec indicates that directory name completion is desired, +the programmable completion functions force Readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the @var{mark-directories} Readline variable, regardless +of the setting of the @var{mark-symlinked-directories} Readline variable. + +There is some support for dynamically modifying completions. This is +most useful when used in combination with a default completion specified +with @option{-D}. It's possible for shell functions executed as completion +handlers to indicate that completion should be retried by returning an +exit status of 124. If a shell function returns 124, and changes +the compspec associated with the command on which completion is being +attempted (supplied as the first argument when the function is executed), +programmable completion restarts from the beginning, with an +attempt to find a new compspec for that command. This allows a set of +completions to be built dynamically as completion is attempted, rather than +being loaded all at once. + +For instance, assuming that there is a library of compspecs, each kept in a +file corresponding to the name of the command, the following default +completion function would load completions dynamically: + +@example +_completion_loader() +@{ + . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124 +@} +complete -D -F _completion_loader -o bashdefault -o default +@end example + +@node Programmable Completion Builtins +@section Programmable Completion Builtins +@cindex completion builtins + +Three builtin commands are available to manipulate the programmable completion +facilities: one to specify how the arguments to a particular command are to +be completed, and two to modify the completion as it is happening. + +@table @code +@item compgen +@btindex compgen +@example +@code{compgen [@var{option}] [@var{word}]} +@end example + +Generate possible completion matches for @var{word} according to +the @var{option}s, which may be any option accepted by the +@code{complete} +builtin with the exception of @option{-p} and @option{-r}, and write +the matches to the standard output. +When using the @option{-F} or @option{-C} options, the various shell variables +set by the programmable completion facilities, while available, will not +have useful values. + +The matches will be generated in the same way as if the programmable +completion code had generated them directly from a completion specification +with the same flags. +If @var{word} is specified, only those completions matching @var{word} +will be displayed. + +The return value is true unless an invalid option is supplied, or no +matches were generated. + +@item complete +@btindex complete +@example +@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-DEI] [-A @var{action}] [-G @var{globpat}] +[-W @var{wordlist}] [-F @var{function}] [-C @var{command}] [-X @var{filterpat}] +[-P @var{prefix}] [-S @var{suffix}] @var{name} [@var{name} @dots{}]} +@code{complete -pr [-DEI] [@var{name} @dots{}]} +@end example + +Specify how arguments to each @var{name} should be completed. +If the @option{-p} option is supplied, or if no options are supplied, existing +completion specifications are printed in a way that allows them to be +reused as input. +The @option{-r} option removes a completion specification for +each @var{name}, or, if no @var{name}s are supplied, all +completion specifications. +The @option{-D} option indicates that other supplied options and actions should +apply to the ``default'' command completion; that is, completion attempted +on a command for which no completion has previously been defined. +The @option{-E} option indicates that other supplied options and actions should +apply to ``empty'' command completion; that is, completion attempted on a +blank line. +The @option{-I} option indicates that other supplied options and actions should +apply to completion on the inital non-assignment word on the line, or after a +command delimiter such as @samp{;} or @samp{|}, which is usually command +name completion. +If multiple options are supplied, the @option{-D} option takes precedence +over @option{-E}, and both take precedence over @option{-I}. +If any of @option{-D}, @option{-E}, or @option{-I} are supplied, any other +@var{name} arguments are ignored; these completions only apply to the case +specified by the option. + +The process of applying these completion specifications when word completion +is attempted is described above (@pxref{Programmable Completion}). + +Other options, if specified, have the following meanings. +The arguments to the @option{-G}, @option{-W}, and @option{-X} options +(and, if necessary, the @option{-P} and @option{-S} options) +should be quoted to protect them from expansion before the +@code{complete} builtin is invoked. + + +@table @code +@item -o @var{comp-option} +The @var{comp-option} controls several aspects of the compspec's behavior +beyond the simple generation of completions. +@var{comp-option} may be one of: + +@table @code + +@item bashdefault +Perform the rest of the default Bash completions if the compspec +generates no matches. + +@item default +Use Readline's default filename completion if the compspec generates +no matches. + +@item dirnames +Perform directory name completion if the compspec generates no matches. + +@item filenames +Tell Readline that the compspec generates filenames, so it can perform any +filename-specific processing (like adding a slash to directory names, +quoting special characters, or suppressing trailing spaces). +This option is intended to be used with shell functions specified +with @option{-F}. + +@item noquote +Tell Readline not to quote the completed words if they are filenames +(quoting filenames is the default). + +@item nosort +Tell Readline not to sort the list of possible completions alphabetically. + +@item nospace +Tell Readline not to append a space (the default) to words completed at +the end of the line. + +@item plusdirs +After any matches defined by the compspec are generated, +directory name completion is attempted and any +matches are added to the results of the other actions. + +@end table + +@item -A @var{action} +The @var{action} may be one of the following to generate a list of possible +completions: + +@table @code +@item alias +Alias names.

This function uses the word passed as @code{$2} +to determine the directory name to complete. You can also use the +@code{COMP_WORDS} array variable; the current word is indexed by the +@code{COMP_CWORD} variable. + +The function relies on the @code{complete} and @code{compgen} builtins +to do much of the work, adding only the things that the Bash @code{cd} +does beyond accepting basic directory names: +tilde expansion (@pxref{Tilde Expansion}), +searching directories in @var{$CDPATH}, which is described above +(@pxref{Bourne Shell Builtins}), +and basic support for the @code{cdable_vars} shell option +(@pxref{The Shopt Builtin}). +@code{_comp_cd} modifies the value of @var{IFS} so that it contains only +a newline to accommodate file names containing spaces and tabs -- +@code{compgen} prints the possible completions it generates one per line. + +Possible completions go into the @var{COMPREPLY} array variable, one +completion per array element. The programmable completion system retrieves +the completions from there when the function returns. + +@example +# A completion function for the cd builtin +# based on the cd completion function from the bash_completion package +_comp_cd() +@{ + local IFS=$' \t\n' # normalize IFS + local cur _skipdot _cdpath + local i j k + + # Tilde expansion, which also expands tilde to full pathname + case "$2" in + \~*) eval cur="$2" ;; + *) cur=$2 ;; + esac + + # no cdpath or absolute pathname -- straight directory completion + if [[ -z "$@{CDPATH:-@}" ]] || [[ "$cur" == @@(./*|../*|/*) ]]; then + # compgen prints paths one per line; could also use while loop + IFS=$'\n' + COMPREPLY=( $(compgen -d -- "$cur") ) + IFS=$' \t\n' + # CDPATH+directories in the current directory if not in CDPATH + else + IFS=$'\n' + _skipdot=false + # preprocess CDPATH to convert null directory names to . + _cdpath=$@{CDPATH/#:/.:@} + _cdpath=$@{_cdpath//::/:.:@} + _cdpath=$@{_cdpath/%:/:.@} + for i in $@{_cdpath//:/$'\n'@}; do + if [[ $i -ef . ]]; then _skipdot=true; fi + k="$@{#COMPREPLY[@@]@}" + for j in $( compgen -d -- "$i/$cur" ); do + COMPREPLY[k++]=$@{j#$i/@} # cut off directory + done + done + $_skipdot || COMPREPLY+=( $(compgen -d -- "$cur") ) + IFS=$' \t\n' + fi + + # variable names if appropriate shell option set and no completions + if shopt -q cdable_vars && [[ $@{#COMPREPLY[@@]@} -eq 0 ]]; then + COMPREPLY=( $(compgen -v -- "$cur") ) + fi + + return 0 +@} +@end example + +We install the completion function using the @option{-F} option to +@code{complete}: + +@example +# Tell readline to quote appropriate and append slashes to directories; +# use the bash default completion for other arguments +complete -o filenames -o nospace -o bashdefault -F _comp_cd cd +@end example + +@noindent +Since we'd like Bash and Readline to take care of some +of the other details for us, we use several other options to tell Bash +and Readline what to do. The @option{-o filenames} option tells Readline +that the possible completions should be treated as filenames, and quoted +appropriately. That option will also cause Readline to append a slash to +filenames it can determine are directories (which is why we might want to +extend @code{_comp_cd} to append a slash if we're using directories found +via @var{CDPATH}: Readline can't tell those completions are directories). +The @option{-o nospace} option tells Readline to not append a space +character to the directory name, in case we want to append to it. +The @option{-o bashdefault} option brings in the rest of the "Bash default" +completions -- possible completion that Bash adds to the default Readline +set. These include things like command name completion, variable completion +for words beginning with @samp{@{}, completions containing pathname +expansion patterns (@pxref{Filename Expansion}), and so on. + +Once installed using @code{complete}, @code{_comp_cd} will be called every +time we attempt word completion for a @code{cd} command. + +Many more examples -- an extensive collection of completions for most of +the common GNU, Unix, and Linux commands -- are available as part of the +bash_completion project. This is installed by default on many GNU/Linux +distributions. Originally written by Ian Macdonald, the project now lives +at @url{http://bash-completion.alioth.debian.org/}.

This is the traditional TeX use. + \`tidy' compile in a local *.t2d directory, where the auxiliary files + are left. Output files are copied back to the original file. + \`clean' same as \`tidy', but remove the auxiliary directory afterwards. + Every compilation therefore requires the full cycle. + +Using the \`tidy' mode brings several advantages: + - the current directory is not cluttered with plethora of temporary files. + - clutter can be even further reduced using --build-dir=dir: all the *.t2d + directories are stored there. + - clutter can be reduced to zero using, e.g., --build-dir=/tmp/\$USER.t2d + or --build-dir=\$HOME/.t2d. + - the output file is updated after every successful TeX run, for + sake of concurrent visualization of the output. In a \`local' build + the viewer stops during the whole TeX run. + - if the compilation fails, the previous state of the output file + is preserved. + - PDF and DVI compilation are kept in separate subdirectories + preventing any possibility of auxiliary file incompatibility. + +On the other hand, because \`tidy' compilation takes place in another +directory, occasionally TeX won't be able to find some files (e.g., when +using \\graphicspath): in that case, use -I to specify the additional +directories to consider. + +The values of the BIBER, BIBTEX, DVIPDF, DVIPS, HEVEA, LATEX, MAKEINDEX, +MAKEINFO, PDFLATEX, PDFTEX, SED, T4HT, TEX, TEX4HT, TEXINDEX, and THUMBPDF_CMD +environment variables are used to run those commands, if they are set. + +Regarding --dvipdf, if DVIPDF is not set in the environment, the +following programs are looked for (in this order): dvipdfmx dvipdfm +dvipdf dvi2pdf dvitopdf. + +Any CMD strings are added after @setfilename for Texinfo input, or in +the first line for LaTeX input. + +Report bugs to bug-texinfo@gnu.org, +general questions and discussion to help-texinfo@gnu.org. +GNU Texinfo home page: <http://www.gnu.org/software/texinfo/> +General help using GNU software: <http://www.gnu.org/gethelp/> +EOF + exit 0 +} + + +# verbose WORD1 WORD2 +# ------------------- +# Report some verbose information. +verbose () +{ + if $verb; then + echo >&2 "$0: $@" + fi +} + + +# version +# ------- +# Display version info and exit successfully. +version () +{ + cat <<EOF +texi2dvi (GNU Texinfo 5.2) $rcs_version + +Copyright (C) 2014 Free Software Foundation, Inc. +License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> +This is free software: you are free to change and redistribute it. +There is NO WARRANTY, to the extent permitted by law. +EOF + exit 0 +} + + +## ---------------- ## +## Handling lists. ## +## ---------------- ## + + +# list_append LIST-NAME ELEM +# -------------------------- +# Set LIST-NAME to its former contents, with ELEM appended. +list_append () +{ + local la_l="$1" + shift + eval set X \$$la_l "$@" + shift + eval $la_l=\""$@"\" +} + + +# list_concat_dirs LIST-NAME DIR-LIST +# ----------------------------------- +# Append to LIST-NAME all the components (included empty) from +# the $path_sep separated list DIR-LIST.

Specifically, I've been using the perl +version Term::ReadLine::Gnu. It works great. + +Anyway, I've been playing around the alternate interface and I wanted +to contribute a little C program, callback.c, to you that you could +use as an example of the alternate interface in the /examples +directory of the readline distribution. + +My example shows how, using the alternate interface, you can +interactively change the prompt (which is very nice imo). Also, I +point out that you must roll your own terminal setting when using the +alternate interface because readline depreps (using your parlance) the +terminal while in the user callback. I try to demostrate what I mean +with an example. I've included the program below. + +To compile, I just put the program in the examples directory and made +the appropriate changes to the EXECUTABLES and OBJECTS line and added +an additional target 'callback'. + +I compiled on my Sun Solaris2.6 box using Sun's cc. + +Let me know what you think. + +Jeff +*/ +/* +Copyright (C) 1999 Jeff Solomon +*/ + +#if defined (HAVE_CONFIG_H) +#include <config.h> +#endif + +#include <sys/types.h> + +#ifdef HAVE_UNISTD_H +#include <unistd.h> +#endif +#include <stdlib.h> + +#include <stdio.h> +#include <termios.h> /* xxx - should make this more general */ + +#ifdef READLINE_LIBRARY +# include "readline.h" +#else +# include <readline/readline.h> +#endif + +#ifndef STDIN_FILENO +# define STDIN_FILENO 0 +#endif + +/* This little examples demonstrates the alternate interface to using readline. + * In the alternate interface, the user maintains control over program flow and + * only calls readline when STDIN is readable. Using the alternate interface, + * you can do anything else while still using readline (like talking to a + * network or another program) without blocking. + * + * Specifically, this program highlights two importants features of the + * alternate interface. 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?

It is a shared library that redirects calls to fgets(stdin) +to readline() via LD_PRELOAD, and it supports a custom prompt and list of +command names. Many people have asked me for this file, so I thought I'd +pass it your way in hope of just including it with readline to begin with. + +Best Regards, + +-Harold +*/ + +/****************************************************************************** +******************************************************************************* + + FILE NAME: fgets.c TARGET: libfgets.so + AUTHOR: Harold Levy VERSION: 1.0 + hlevy@synopsys.com + + ABSTRACT: Customize fgets() behavior via LD_PRELOAD in the following ways: + + -- If fgets(stdin) is called, redirect to GNU readline() to obtain + command-line editing, file-name completion, history, etc. + + -- A list of commands for command-name completion can be configured by + setting the environment-variable FGETS_COMMAND_FILE to a file containing + the list of commands to be used. + + -- Command-line editing with readline() works best when the prompt string + is known; you can set this with the FGETS_PROMPT environment variable. + + -- There special strings that libfgets will interpret as internal commands: + + _fgets_reset_ reset the command list + + _fgets_dump_ dump status + + _fgets_debug_ toggle debug messages + + HOW TO BUILD: Here are examples of how to build libfgets.so on various + platforms; you will have to add -I and -L flags to configure access to + the readline header and library files. + + (32-bit builds with gcc) + AIX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap + HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline + Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline + SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline + + (64-bit builds without gcc) + SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \ + -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline + + HOW TO USE: Different operating systems have different levels of support + for the LD_PRELOAD concept. 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.

This basically means you can run your entire +session (including bash and terminal-mode emacs) under rlfe. + +FEATURES + +* Can use all readline commands (and history) in commands that +read input lines in "canonical mode" - even 'cat'! + +* Automatically switches between "readline-editing mode" and "raw mode" +depending on the terminal mode. If the inferior program invokes +readline itself, it will do its own line editing. (The inferior +readline will not know about rlfe, and it will have its own history.) +You can even run programs like 'emavs -nw' and 'vi' under rlfe. +The goal is you could leave rlfe always on without even knowing +about it. (We're not quite there, but it works tolerably well.) + +* The input line (after any prompt) is changed to bold-face. + +INSTALL + +The usual: ./configure && make && make install + +Note so far rlfe has only been tested on GNU Linux (Fedora Core 2) +and Mac OS X (10.3). + +This assumes readline header files and libraries are in the default +places. If not, you can create a link named readline pointing to the +readline sources. To link with libreadline.a and libhistory.a +you can copy or link them, or add LDFLAGS='-/path/to/readline' to +the make command-line. + +USAGE + +Just run it. That by default runs bash. You can run some other +command by giving it as command-line arguments. + +There are a few tweaks: -h allows you to name the history file, +and -s allows you to specify its size. It default to "emacs" mode, +but if the the environment variable EDITOR is set to "vi" that +mode is chosen. + +ISSUES + +* The mode switching depends on the terminal mode set by the inferior +program. Thus ssh/telnet/screen-type programs will typically be in +raw mode, so rlfe won't be much use, even if remote programs run in +canonical mode. The work-around is to run rlfe on the remote end. + +* Echo supression and prompt recognition are somewhat fragile. +(A protocol so that the o/s tty code can reliably communicate its +state to rlfe could solve this problem, and the previous one.) + +* See the intro to rlfe.c for more notes. + +* Assumes a VT100-compatible terminal, though that could be generalized +if anybody cares. + +* Requires ncurses. + +* It would be useful to integrate rlfe's logic in a terminal emulator. +That would make it easier to reposition the edit position with a mouse, +integrate cut-and-paste with the system clipboard, and more robustly +handle escape sequence and multi-byte characters more robustly. + +AUTHOR + +Per Bothner <per@bothner.com> + +LICENSE + +GPL. diff --git a/readline/readline/examples/rlfe/config.h.in b/readline/readline/examples/rlfe/config.h.in new file mode 100644 index 00000000000..a843fecc4ac --- /dev/null +++ b/readline/readline/examples/rlfe/config.h.in @@ -0,0 +1,383 @@ +/* Copyright 2004 Per Bothner <per@bothner.com> + * Based on config.h from screen-4.0.2. + * Copyright (c) 1993-2000 + * Juergen Weigert (jnweiger@immd4.informatik.uni-erlangen.de) + * Michael Schroeder (mlschroe@immd4.informatik.uni-erlangen.de) + * Copyright (c) 1987 Oliver Laumann + * + * 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.

Interoperability between terminal-line + * applications and (teletype-style) character terminals using the + * UTF-8 encoding requires agreement on which character should advance + * the cursor by how many cell positions. No established formal + * standards exist at present on which Unicode character shall occupy + * how many cell positions on character terminals. These routines are + * a first attempt of defining such behavior based on simple rules + * applied to data provided by the Unicode Consortium. + * + * For some graphical characters, the Unicode standard explicitly + * defines a character-cell width via the definition of the East Asian + * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes. + * In all these cases, there is no ambiguity about which width a + * terminal shall use. For characters in the East Asian Ambiguous (A) + * class, the width choice depends purely on a preference of backward + * compatibility with either historic CJK or Western practice. + * Choosing single-width for these characters is easy to justify as + * the appropriate long-term solution, as the CJK practice of + * displaying these characters as double-width comes from historic + * implementation simplicity (8-bit encoded characters were displayed + * single-width and 16-bit ones double-width, even for Greek, + * Cyrillic, etc.) and not any typographic considerations. + * + * Much less clear is the choice of width for the Not East Asian + * (Neutral) class. Existing practice does not dictate a width for any + * of these characters. It would nevertheless make sense + * typographically to allocate two character cells to characters such + * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be + * represented adequately with a single-width glyph. The following + * routines at present merely assign a single-cell width to all + * neutral characters, in the interest of simplicity. This is not + * entirely satisfactory and should be reconsidered before + * establishing a formal standard in this area. At the moment, the + * decision which Not East Asian (Neutral) characters should be + * represented by double-width glyphs cannot yet be answered by + * applying a simple rule from the Unicode database content. Setting + * up a proper standard for the behavior of UTF-8 character terminals + * will require a careful analysis not only of each Unicode character, + * but also of each presentation form, something the author of these + * routines has avoided to do so far. + * + * http://www.unicode.org/unicode/reports/tr11/ + * + * Markus Kuhn -- 2007-05-26 (Unicode 5.0) + * + * Permission to use, copy, modify, and distribute this software + * for any purpose and without fee is hereby granted.
