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-4.3.orig/COPYING b/readline-4.3.orig/COPYING deleted file mode 100644 index 1bf1526..0000000 --- a/readline-4.3.orig/COPYING +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it.

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

If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes some time. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile readline and build the static readline - and history libraries. If supported, the shared readline and history - libraries will be built also. See below for instructions on compiling - the other parts of the distribution. Typing `make everything' will - cause the static and shared libraries (if supported) and the example - programs to be built. - - 3. Type `make install' to install the static readline and history - libraries, the readline include files, the documentation, and, if - supported, the shared readline and history libraries. - - 4. You can remove the created libraries and object files from the - build directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile readline for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the readline developers, and should be used with care. - -The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It -uses those values to create a `Makefile' in the build directory, -and Makefiles in the `doc', `shlib', and `examples' -subdirectories. It also creates a `config.h' file containing -system-dependent definitions. Finally, it creates a shell script -`config.status' that you can run in the future to recreate the -current configuration, a file `config.cache' that saves the -results of its tests to speed up reconfiguring, and a file -`config.log' containing compiler output (useful mainly for -debugging `configure'). - -If you need to do unusual things to compile readline, please try -to figure out how `configure' could check whether to do them, and -mail diffs or instructions to <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_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_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-4.3.orig/MANIFEST b/readline-4.3.orig/MANIFEST deleted file mode 100644 index 1507eda..0000000 --- a/readline-4.3.orig/MANIFEST +++ /dev/null @@ -1,126 +0,0 @@ -# -# Master distribution manifest for the standalone readline distribution -# -doc d -examples d -support d -shlib d -COPYING f -README f -MANIFEST f -INSTALL f -CHANGELOG f -CHANGES f -USAGE f -aclocal.m4 f -config.h.in f -configure f -configure.in f -Makefile.in f -ansi_stdlib.h f -chardefs.h f -history.h f -histlib.h f -keymaps.h f -posixdir.h f -posixjmp.h f -posixstat.h f -readline.h f -rlconf.h f -rldefs.h f -rlmbutil.h f -rlprivate.h f -rlshell.h f -rlstdc.h f -rltty.h f -rltypedefs.h f -rlwinsize.h f -tcap.h f -tilde.h f -xmalloc.h f -bind.c f -callback.c f -compat.c f -complete.c f -display.c f -emacs_keymap.c f -funmap.c f -input.c f -isearch.c f -keymaps.c f -kill.c f -macro.c f -mbutil.c f -misc.c f -nls.c f -parens.c f -readline.c f -rltty.c f -savestring.c f -search.c f -shell.c f -signals.c f -terminal.c f -text.c f -tilde.c f -undo.c f -util.c f -vi_keymap.c f -vi_mode.c f -xmalloc.c f -history.c f -histexpand.c f -histfile.c f -histsearch.c f -shlib/Makefile.in f -support/config.guess f -support/config.sub f -support/install.sh f -support/mkdirs f -support/mkdist f -support/shobj-conf f -support/shlib-install f -support/wcwidth.c f -doc/Makefile.in f -doc/texinfo.tex f -doc/manvers.texinfo f -doc/rlman.texinfo f -doc/rltech.texinfo f -doc/rluser.texinfo f -doc/rluserman.texinfo f -doc/hist.texinfo f -doc/hstech.texinfo f -doc/hsuser.texinfo 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/rlcat.c f -examples/rlfe.c f -examples/rltest.c f -examples/rl.c f -examples/rlversion.c f -examples/histexamp.c f -examples/Inputrc 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 diff --git a/readline-4.3.orig/Makefile.in b/readline-4.3.orig/Makefile.in deleted file mode 100644 index 0ff0c31..0000000 --- a/readline-4.3.orig/Makefile.in +++ /dev/null @@ -1,520 +0,0 @@ -## -*- text -*- ## -# Master Makefile for the GNU readline library. -# Copyright (C) 1994 Free Software Foundation, Inc. - -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2, or (at your option) -# any later version. - -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

-This is the Gnu Readline library, version 4.3. - -The Readline library provides a set of functions for use by applications -that allow users to edit command lines as they are typed in. Both -Emacs and vi editing modes are available. The Readline library includes -additional functions to maintain a list of previously-entered command -lines, to recall and perhaps reedit those lines, and perform csh-like -history expansion on previous commands. - -The history facilites are also placed into a separate library, the -History library, as part of the build process. The History library -may be used without Readline in applications which desire its -capabilities. - -The Readline library is free software, distributed under the terms of -the [GNU] General Public License, version 2. For more information, see -the file COPYING. - -To build the library, try typing `./configure', then `make'. The -configuration process is automated, so no further intervention should -be necessary. Readline builds with `gcc' by default if it is -available. If you want to use `cc' instead, type - - CC=cc ./configure - -if you are using a Bourne-style shell. If you are not, the following -may work: - - env CC=cc ./configure - -Read the file INSTALL in this directory for more information about how -to customize and control the build process. - -The file rlconf.h contains C preprocessor defines that enable and disable -certain Readline features. - -The special make target `everything' will build the static and shared -libraries (if the target platform supports them) and the examples. - -Examples -======== - -There are several example programs that use Readline features in the -examples directory. The `rl' program is of particular interest. It -is a command-line interface to Readline, suitable for use in shell -scripts in place of `read'. - -Shared Libraries -================ - -There is skeletal support for building shared versions of the -Readline and History libraries. The configure script creates -a Makefile in the `shlib' subdirectory, and typing `make shared' -will cause shared versions of the Readline and History libraries -to be built on supported platforms. - -If `configure' is given the `--enable-shared' option, it will attempt -to build the shared libraries by default on supported platforms. - -Configure calls the script support/shobj-conf to test whether or -not shared library creation is supported and to generate the values -of variables that are substituted into shlib/Makefile. If you -try to build shared libraries on an unsupported platform, `make' -will display a message asking you to update support/shobj-conf for -your platform. - -If you need to update support/shobj-conf, you will need to create -a `stanza' for your operating system and compiler. The script uses -the value of host_os and ${CC} as determined by configure. For -instance, FreeBSD 4.2 with any version of gcc is identified as -`freebsd4.2-gcc*'. - -In the stanza for your operating system-compiler pair, you will need to -define several variables. They are: - -SHOBJ_CC The C compiler used to compile source files into shareable - object files. This is normally set to the value of ${CC} - by configure, and should not need to be changed. - -SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create - position-independent code. If you are using gcc, this - should probably be set to `-fpic'. - -SHOBJ_LD The link editor to be used to create the shared library from - the object files created by $SHOBJ_CC. If you are using - gcc, a value of `gcc' will probably work. - -SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. - If you are using gcc, `-shared' may be all that is necessary. - These should be the flags needed for generic shared object - creation. - -SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library - creation. Many systems use the -R option to the link - editor to embed a path within the library for run-time - library searches. A reasonable value for such systems would - be `-R$(libdir)'. - -SHLIB_LIBS Any additional libraries that shared libraries should be - linked against when they are created. - -SHLIB_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_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. - -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@po.cwru.edu diff --git a/readline-4.3.orig/USAGE b/readline-4.3.orig/USAGE deleted file mode 100644 index edc9f54..0000000 --- a/readline-4.3.orig/USAGE +++ /dev/null @@ -1,37 +0,0 @@ -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.

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 _e_v_e_n_t, and the portions - of that line that are acted upon are _w_o_r_d_s. Various _m_o_d_i_- - _f_i_e_r_s are available to manipulate the selected words.

The GNU -History library is able to keep track of those lines, associate arbitrary -data with each line, and utilize information from previous lines in -composing new ones. -.PP -.SH "HISTORY EXPANSION" -.PP -The history library supports a history expansion feature that -is identical to the history expansion in -.BR bash. -This section describes what syntax features are available. -.PP -History expansions introduce words from the history list into -the input stream, making it easy to repeat commands, insert the -arguments to a previous command into the current input line, or -fix errors in previous commands quickly. -.PP -History expansion is usually performed immediately after a complete line -is read. -It takes place in two parts. -The first is to determine which line from the history list -to use during substitution. -The second is to select portions of that line for inclusion into -the current one. -The line selected from the history is the \fIevent\fP, -and the portions of that line that are acted upon are \fIwords\fP. -Various \fImodifiers\fP are available to manipulate the selected words. -The line is broken into words in the same fashion as \fBbash\fP -does when reading input, -so that several words that would otherwise be separated -are considered one word when surrounded by quotes (see the -description of \fBhistory_tokenize()\fP below). -History expansions are introduced by the appearance of the -history expansion character, which is \^\fB!\fP\^ by default. -Only backslash (\^\fB\e\fP\^) and single quotes can quote -the history expansion character. -.SS Event Designators -.PP -An event designator is a reference to a command line entry in the -history list. -.PP -.PD 0 -.TP -.B ! -Start a history substitution, except when followed by a -.BR blank , -newline, = or (. -.TP -.B !\fIn\fR -Refer to command line -.IR n . -.TP -.B !\-\fIn\fR -Refer to the current command line minus -.IR n . -.TP -.B !! -Refer to the previous command. This is a synonym for `!\-1'. -.TP -.B !\fIstring\fR -Refer to the most recent command starting with -.IR string . -.TP -.B !?\fIstring\fR\fB[?]\fR -Refer to the most recent command containing -.IR string . -The trailing \fB?\fP may be omitted if -.I string -is followed immediately by a newline. -.TP -.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u -Quick substitution. Repeat the last command, replacing -.I string1 -with -.IR string2 . -Equivalent to -``!!:s/\fIstring1\fP/\fIstring2\fP/'' -(see \fBModifiers\fP below). -.TP -.B !# -The entire command line typed so far. -.PD -.SS Word Designators -.PP -Word designators are used to select desired words from the event. -A -.B : -separates the event specification from the word designator. -It may be omitted if the word designator begins with a -.BR ^ , -.BR $ , -.BR * , -.BR \- , -or -.BR % . -Words are numbered from the beginning of the line, -with the first word being denoted by 0 (zero). -Words are inserted into the current line separated by single spaces. -.PP -.PD 0 -.TP -.B 0 (zero) -The zeroth word. For the shell, this is the command -word. -.TP -.I n -The \fIn\fRth word. -.TP -.B ^ -The first argument. That is, word 1. -.TP -.B $ -The last argument. -.TP -.B % -The word matched by the most recent `?\fIstring\fR?' search. -.TP -.I x\fB\-\fPy -A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'. -.TP -.B * -All of the words but the zeroth. This is a synonym -for `\fI1\-$\fP'. It is not an error to use -.B * -if there is just one -word in the event; the empty string is returned in that case. -.TP -.B x* -Abbreviates \fIx\-$\fP. -.TP -.B x\- -Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word. -.PD -.PP -If a word designator is supplied without an event specification, the -previous command is used as the event. -.SS Modifiers -.PP -After the optional word designator, there may appear a sequence of -one or more of the following modifiers, each preceded by a `:'. -.PP -.PD 0 -.PP -.TP -.B h -Remove a trailing file name component, leaving only the head. -.TP -.B t -Remove all leading file name components, leaving the tail. -.TP -.B r -Remove a trailing suffix of the form \fI.xxx\fP, leaving the -basename. -.TP -.B e -Remove all but the trailing suffix. -.TP -.B p -Print the new command but do not execute it. -.TP -.B q -Quote the substituted words, escaping further substitutions. -.TP -.B x -Quote the substituted words as with -.BR q , -but break into words at -.B blanks -and newlines. -.TP -.B s/\fIold\fP/\fInew\fP/ -Substitute -.I new -for the first occurrence of -.I old -in the event line. Any delimiter can be used in place of /. The -final delimiter is optional if it is the last character of the -event line. The delimiter may be quoted in -.I old -and -.I new -with a single backslash. If & appears in -.IR new , -it is replaced by -.IR old . -A single backslash will quote the &. If -.I old -is null, it is set to the last -.I old -substituted, or, if no previous history substitutions took place, -the last -.I string -in a -.B !?\fIstring\fR\fB[?]\fR -search. -.TP -.B & -Repeat the previous substitution. -.TP -.B g -Cause changes to be applied over the entire event line. This is -used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR') -or `\fB:&\fP'. If used with -`\fB:s\fP', any delimiter can be used -in place of /, and the final delimiter is optional -if it is the last character of the event line. -.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; - 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 returns the previously-set -maximum number of history entries (as set by \fBstifle_history()\fP). -history was stifled. The value is positive if the history was -stifled, negative if it wasn't. - -.Fn1 int history_is_stifled "void" -Returns non-zero if the history is stifled, zero if it is not. - -.SS Information About the History List - -These functions return information about the entire history list or -individual list entries. - -.Fn1 "HIST_ENTRY **" history_list "void" -Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the -current input history.

If there is no previous entry, return -a \fBNULL\fP pointer. - -.Fn1 "HIST_ENTRY *" next_history "void" -Move the current history offset forward to the next history entry, and -return the a pointer to that entry. If there is no next entry, return -a \fBNULL\fP pointer. - -.SS Searching the History List - -These functions allow searching of the history list for entries containing -a specific string. Searching may be performed both forward and backward -from the current history position. The search may be \fIanchored\fP, -meaning that the string must match at the beginning of the history entry. - -.Fn2 int history_search "const char *string" "int direction" -Search the history for \fIstring\fP, starting at the current history offset. -If \fIdirection\fP is less than 0, then the search is through -previous entries, otherwise through subsequent entries. -If \fIstring\fP is found, then -the current history index is set to that history entry, and the value -returned is the offset in the line of the entry where -\fIstring\fP was found. Otherwise, nothing is changed, and a -1 is -returned. - -.Fn2 int history_search_prefix "const char *string" "int direction" -Search the history for \fIstring\fP, starting at the current history -offset. The search is anchored: matching lines must begin with -\fIstring\fP.

Returns the absolute -index of the history element where \fIstring\fP was found, or -1 otherwise. - -.SS Managing the History File -The History library can read the history from and write it to a file. -This section documents the functions for managing a history file. - -.Fn1 int read_history "const char *filename" -Add the contents of \fIfilename\fP to the history list, a line at a time. -If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP. -Returns 0 if successful, or \fBerrno\fP if not. - -.Fn3 int read_history_range "const char *filename" "int from" "int to" -Read a range of lines from \fIfilename\fP, adding them to the history list. -Start reading at line \fIfrom\fP and end at \fIto\fP. -If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than -\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is -\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful, -or \fBerrno\fP if not. - -.Fn1 int write_history "const char *filename" -Write the current history to \fIfilename\fP, overwriting \fIfilename\fP -if necessary. -If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP. -Returns 0 on success, or \fBerrno\fP on a read or write error. - - -.Fn2 int append_history "int nelements" "const char *filename" -Append the last \fInelements\fP of the history list to \fIfilename\fP. -If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP. -Returns 0 on success, or \fBerrno\fP on a read or write error. - -.Fn2 int history_truncate_file "const char *filename" "int nlines" -Truncate the history file \fIfilename\fP, leaving only the last -\fInlines\fP lines. -If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated. -Returns 0 on success, or \fBerrno\fP on failure. - -.SS History Expansion - -These functions implement history expansion. - -.Fn2 int history_expand "char *string" "char **output" -Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer -to a string.

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. - - 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 "event", and the portions of that line that are acted upon -are called "words". Various "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 `!' by default. - -* Menu: - -* Event Designators:: How to specify which history line to use. -* Word Designators:: Specifying which words are of interest. -* Modifiers:: Modifying the results of substitution. - - -File: history.info, Node: Event Designators, Next: Word Designators, Up: History Interaction - -Event Designators ------------------ - - An event designator is a reference to a command line entry in the -history list. - -`!' - Start a history substitution, except when followed by a space, tab, - the end of the line, `=' or `('. - -`!N' - Refer to command line N. - -`!-N' - Refer to the command N lines back. - -`!!' - Refer to the previous command. This is a synonym for `!-1'. - -`!STRING' - Refer to the most recent command starting with STRING. - -`!?STRING[?]' - Refer to the most recent command containing STRING. The trailing - `?' may be omitted if the STRING is followed immediately by a - newline. - -`^STRING1^STRING2^' - Quick Substitution. Repeat the last command, replacing STRING1 - with STRING2.

A -`:' separates the event specification from the word designator. It may -be omitted if the word designator begins with a `^', `$', `*', `-', or -`%'. Words are numbered from the beginning of the line, with the first -word being denoted by 0 (zero). Words are inserted into the current -line separated by single spaces. - - For example, - -`!!' - designates the preceding command. When you type this, the - preceding command is repeated in toto. - -`!!:$' - designates the last argument of the preceding command. This may be - shortened to `!$'. - -`!fi:2' - designates the second argument of the most recent command starting - with the letters `fi'. - - Here are the word designators: - -`0 (zero)' - The `0'th word. For many applications, this is the command word. - -`N' - The Nth word. - -`^' - The first argument; that is, word 1. - -`$' - The last argument. - -`%' - The word matched by the most recent `?STRING?' search. - -`X-Y' - A range of words; `-Y' abbreviates `0-Y'. - -`*' - All of the words, except the `0'th. This is a synonym for `1-$'. - It is not an error to use `*' if there is just one word in the - event; the empty string is returned in that case. - -`X*' - Abbreviates `X-$' - -`X-' - Abbreviates `X-$' like `X*', but omits the last word. - - If a word designator is supplied without an event specification, the -previous command is used as the event. - - -File: history.info, Node: Modifiers, Prev: Word Designators, Up: History Interaction - -Modifiers ---------- - - After the optional word designator, you can add a sequence of one or -more of the following modifiers, each preceded by a `:'. - -`h' - Remove a trailing pathname component, leaving only the head. - -`t' - Remove all leading pathname components, leaving the tail. - -`r' - Remove a trailing suffix of the form `.SUFFIX', leaving the - basename. - -`e' - Remove all but the trailing suffix. - -`p' - Print the new command but do not execute it. - -`s/OLD/NEW/' - Substitute NEW for the first occurrence of OLD in the event line. - Any delimiter may be used in place of `/'. The delimiter may be - quoted in OLD and NEW with a single backslash. If `&' appears in - NEW, it is replaced by OLD. A single backslash will quote the - `&'. The final delimiter is optional if it is the last character - on the input line. - -`&' - Repeat the previous substitution. - -`g' - Cause changes to be applied over the entire event line.

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. - - 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 "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 `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 `<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. - - -File: history.info, Node: History Storage, Next: History Functions, Prev: Introduction to History, Up: Programming with GNU History - -History Storage -=============== - - The history list is an array of history entries.

QCHAR is a - character that is allowed to end the event specification in - addition to the "normal" terminating characters. - - - Function: char ** history_tokenize (const char *string) - Return an array of tokens parsed out of STRING, much as the shell - might. The tokens are split on the characters in the - HISTORY_WORD_DELIMITERS variable, and shell quoting conventions - are obeyed. - - - Function: char * history_arg_extract (int first, int last, const - char *string) - Extract a string segment consisting of the FIRST through LAST - arguments present in STRING. Arguments are split using - `history_tokenize'. - - -File: history.info, Node: History Variables, Next: History Programming Example, Prev: History Functions, Up: Programming with GNU History - -History Variables -================= - - This section describes the externally-visible variables exported by -the GNU History Library. - - - Variable: int history_base - The logical offset of the first entry in the history list. - - - Variable: int history_length - The number of entries currently stored in the history list. - - - Variable: int history_max_entries - The maximum number of history entries. This must be changed using - `stifle_history()'. - - - Variable: char history_expansion_char - The character that introduces a history event. The default is `!'. - Setting this to 0 inhibits history expansion. - - - Variable: char history_subst_char - The character that invokes word substitution if found at the start - of a line. The default is `^'. - - - Variable: char history_comment_char - During tokenization, if this character is seen as the first - character of a word, then it and all subsequent characters up to a - newline are ignored, suppressing history expansion for the - remainder of the line. This is disabled by default. - - - Variable: char * history_word_delimiters - The characters that separate tokens for `history_tokenize()'. The - default value is `" \t\n()<>;&|"'. - - - Variable: char * history_no_expand_chars - The list of characters which inhibit history expansion if found - immediately following HISTORY_EXPANSION_CHAR. The default is - space, tab, newline, carriage return, and `='. - - - Variable: char * history_search_delimiter_chars - The list of additional characters which can delimit a history - search string, in addition to space, TAB, `:' and `?' in the case - of a substring search. The default is empty. - - - Variable: int history_quotes_inhibit_expansion - If non-zero, single-quoted words are not scanned for the history - expansion character. The default value is 0. - - - Variable: rl_linebuf_func_t * history_inhibit_expansion_function - This should be set to the address of a function that takes two - arguments: a `char *' (STRING) and an `int' index into that string - (I). It should return a non-zero value if the history expansion - starting at STRING[I] should not be performed; zero if the - expansion should be done. It is intended for use by applications - like Bash that use the history expansion character for additional - purposes. By default, this variable is set to `NULL'. - - -File: history.info, Node: History Programming Example, Prev: History Variables, Up: Programming with GNU History - -History Programming Example

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.

There are only a few basic constructs allowed in - the readline init file. Blank lines are ignored. Lines - beginning with a ## are comments. Lines beginning with a $$ - indicate conditional constructs. Other lines denote key - bindings and variable settings. Each program using this - library may add its own commands and bindings. - - For example, placing - - M-Control-u: universal-argument - or - C-Meta-u: universal-argument - - into the _i_n_p_u_t_r_c would make M-C-u execute the readline - command _u_n_i_v_e_r_s_a_l_-_a_r_g_u_m_e_n_t. - - The following symbolic character names are recognized - while processing key bindings: _D_E_L, _E_S_C, _E_S_C_A_P_E, _L_F_D, _N_E_W_- - _L_I_N_E, _R_E_T, _R_E_T_U_R_N, _R_U_B_O_U_T, _S_P_A_C_E, _S_P_C, and _T_A_B. - - In addition to command names, readline allows keys to be - bound to a string that is inserted when the key is pressed - (a _m_a_c_r_o). - - - KKeeyy BBiinnddiinnggss - The syntax for controlling key bindings in the _i_n_p_u_t_r_c - 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 _M_e_t_a_- or - _C_o_n_t_r_o_l_- prefixes, or as a key sequence. - - When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, _k_e_y_- - _n_a_m_e is the name of a key spelled out in English. For - example: - - Control-u: universal-argument - Meta-Rubout: backward-kill-word - Control-o: "> output" - - In the above example, _C_-_u is bound to the function uunniivveerr-- - ssaall--aarrgguummeenntt, _M_-_D_E_L is bound to the function bbaacckk-- - wwaarrdd--kkiillll--wwoorrdd, and _C_-_o is bound to run the macro - expressed on the right hand side (that is, to insert the - text ``> output'' into the line). - - In the second form, ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, kkeeyy-- - sseeqq differs from kkeeyynnaammee 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. - - "\C-u": universal-argument - "\C-x\C-r": re-read-init-file - "\e[11~": "Function Key 1" - - In this example, _C_-_u is again bound to the function uunnii-- - vveerrssaall--aarrgguummeenntt. _C_-_x _C_-_r is bound to the function - rree--rreeaadd--iinniitt--ffiillee, and _E_S_C _[ _1 _1 _~ is bound to insert the - text ``Function Key 1''. - - The full set of GNU Emacs style escape sequences available - when specifying key sequences is - \\CC-- control prefix - \\MM-- meta prefix - \\ee an escape character - \\\\ backslash - \\"" literal ", a double quote - \\'' literal ', a single quote - - In addition to the GNU Emacs style escape sequences, a - second set of backslash escapes is available: - \\aa alert (bell) - \\bb backspace - \\dd delete - \\ff form feed - \\nn newline - \\rr carriage return - \\tt horizontal tab - \\vv vertical tab - \\_n_n_n the eight-bit character whose value is the - octal value _n_n_n (one to three digits) - \\xx_H_H the eight-bit character whose value is the - hexadecimal value _H_H (one or two hex digits) - - 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. Back- - slash will quote any other character in the macro text, - including " and '. - - BBaasshh allows the current readline key bindings to be dis- - played or modified with the bbiinndd builtin command. The - editing mode may be switched during interactive use by - using the --oo option to the sseett builtin command. Other - programs using this library provide similar mechanisms. - The _i_n_p_u_t_r_c file may be edited and re-read if a program - does not provide any other means to incorporate new bind- - ings. - - VVaarriiaabblleess - Readline has variables that can be used to further cus- - tomize its behavior. A variable may be set in the _i_n_p_u_t_r_c - file with a statement of the form - - sseett _v_a_r_i_a_b_l_e_-_n_a_m_e _v_a_l_u_e - - Except where noted, readline variables can take the values - OOnn or OOffff (without regard to case). The variables and - their default values are: - - bbeellll--ssttyyllee ((aauuddiibbllee)) - Controls what happens when readline wants to ring - the terminal bell. If set to nnoonnee, readline never - rings the bell. If set to vviissiibbllee, readline uses a - visible bell if one is available. If set to aauuddii-- - bbllee, readline attempts to ring the terminal's bell. - ccoommmmeenntt--bbeeggiinn ((````##'''')) - The string that is inserted in vvii mode when the - iinnsseerrtt--ccoommmmeenntt command is executed. This command - is bound to MM--## in emacs mode and to ## in vi com- - mand mode. - ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff)) - If set to OOnn, readline performs filename matching - and completion in a case-insensitive fashion. - ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000)) - This determines when the user is queried about - viewing the number of possible completions gener- - ated by the ppoossssiibbllee--ccoommpplleettiioonnss 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 vari- - able, the user is asked whether or not he wishes to - view them; otherwise they are simply listed on the - terminal. - ccoonnvveerrtt--mmeettaa ((OOnn)) - If set to OOnn, 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 - _m_e_t_a _p_r_e_f_i_x). - ddiissaabbllee--ccoommpplleettiioonn ((OOffff)) - If set to OOnn, readline will inhibit word comple- - tion. Completion characters will be inserted into - the line as if they had been mapped to sseellff--iinnsseerrtt. - eeddiittiinngg--mmooddee ((eemmaaccss)) - Controls whether readline begins with a set of key - bindings similar to emacs or vi. eeddiittiinngg--mmooddee can - be set to either eemmaaccss or vvii. - eennaabbllee--kkeeyyppaadd ((OOffff)) - When set to OOnn, readline will try to enable the - application keypad when it is called. Some systems - need this to enable the arrow keys. - eexxppaanndd--ttiillddee ((OOffff)) - If set to oonn, tilde expansion is performed when - readline attempts word completion. - hhiissttoorryy--pprreesseerrvvee--ppooiinntt - If set to oonn, the history code attempts to place - point at the same location on each history line - retrived with pprreevviioouuss--hhiissttoorryy or nneexxtt--hhiissttoorryy. - hhoorriizzoonnttaall--ssccrroollll--mmooddee ((OOffff)) - When set to OOnn, 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. - iinnppuutt--mmeettaa ((OOffff)) - If set to OOnn, readline will enable eight-bit input - (that is, it will not clear the eighth bit in the - characters it reads), regardless of what the termi- - nal claims it can support. The name mmeettaa--ffllaagg is a - synonym for this variable. - iisseeaarrcchh--tteerrmmiinnaattoorrss ((````CC--[[ CC--JJ'''')) - 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 _E_S_C and _C_-_J - will terminate an incremental search. - kkeeyymmaapp ((eemmaaccss)) - Set the current readline keymap. The set of legal - keymap names is _e_m_a_c_s_, _e_m_a_c_s_-_s_t_a_n_d_a_r_d_, _e_m_a_c_s_-_m_e_t_a_, - _e_m_a_c_s_-_c_t_l_x_, _v_i_, _v_i_-_m_o_v_e_, _v_i_-_c_o_m_m_a_n_d, and _v_i_-_i_n_s_e_r_t. - _v_i is equivalent to _v_i_-_c_o_m_m_a_n_d; _e_m_a_c_s is equivalent - to _e_m_a_c_s_-_s_t_a_n_d_a_r_d. The default value is _e_m_a_c_s. - The value of eeddiittiinngg--mmooddee also affects the default - keymap. - mmaarrkk--ddiirreeccttoorriieess ((OOnn)) - If set to OOnn, completed directory names have a - slash appended. - mmaarrkk--mmooddiiffiieedd--lliinneess ((OOffff)) - If set to OOnn, history lines that have been modified - are displayed with a preceding asterisk (**). - mmaarrkk--ssyymmlliinnkkeedd--ddiirreeccttoorriieess ((OOffff)) - If set to OOnn, completed names which are symbolic - links to directories have a slash appended (subject - to the value of mmaarrkk--ddiirreeccttoorriieess). - mmaattcchh--hhiiddddeenn--ffiilleess ((OOnn)) - This variable, when set to OOnn, causes readline to - match files whose names begin with a `.' (hidden - files) when performing filename completion, unless - the leading `.' is supplied by the user in the - filename to be completed. - oouuttppuutt--mmeettaa ((OOffff)) - If set to OOnn, readline will display characters with - the eighth bit set directly rather than as a meta- - prefixed escape sequence. - ppaaggee--ccoommpplleettiioonnss ((OOnn)) - If set to OOnn, readline uses an internal _m_o_r_e-like - pager to display a screenful of possible comple- - tions at a time. - pprriinntt--ccoommpplleettiioonnss--hhoorriizzoonnttaallllyy ((OOffff)) - If set to OOnn, readline will display completions - with matches sorted horizontally in alphabetical - order, rather than down the screen. - sshhooww--aallll--iiff--aammbbiigguuoouuss ((OOffff)) - This alters the default behavior of the completion - functions. If set to oonn, words which have more - than one possible completion cause the matches to - be listed immediately instead of ringing the bell. - vviissiibbllee--ssttaattss ((OOffff)) - If set to OOnn, a character denoting a file's type as - reported by _s_t_a_t(2) is appended to the filename - when listing possible completions. - - CCoonnddiittiioonnaall CCoonnssttrruuccttss - 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 per- - formed as the result of tests. There are four parser - directives used. - - $$iiff The $$iiff construct allows bindings to be made based - on the editing mode, the terminal being used, or - the application using readline. The text of the - test extends to the end of the line; no characters - are required to isolate it. - - mmooddee The mmooddee== form of the $$iiff directive is used - to test whether readline is in emacs or vi - mode. This may be used in conjunction with - the sseett kkeeyymmaapp command, for instance, to set - bindings in the _e_m_a_c_s_-_s_t_a_n_d_a_r_d and _e_m_a_c_s_- - _c_t_l_x keymaps only if readline is starting - out in emacs mode. - - tteerrmm The tteerrmm== form may be used to include termi- - nal-specific key bindings, perhaps to bind - the key sequences output by the terminal's - function keys. The word on the right side - of the == is tested against the full name of - the terminal and the portion of the terminal - name before the first --. This allows _s_u_n to - match both _s_u_n and _s_u_n_-_c_m_d, for instance. - - aapppplliiccaattiioonn - The aapppplliiccaattiioonn construct is used to include - application-specific settings. Each program - using the readline library sets the _a_p_p_l_i_c_a_- - _t_i_o_n _n_a_m_e, and an initialization file can - test for a particular value. This could be - used to bind key sequences to functions use- - ful for a specific program. For instance, - the following command adds a key sequence - that quotes the current or previous word in - Bash: - - $$iiff Bash - # Quote the current or previous word - "\C-xq": "\eb\"\ef\"" - $$eennddiiff - - $$eennddiiff This command, as seen in the previous example, ter- - minates an $$iiff command. - - $$eellssee Commands in this branch of the $$iiff directive are - executed if the test fails. - - $$iinncclluuddee - This directive takes a single filename as an argu- - ment and reads commands and bindings from that - file. For example, the following directive would - read _/_e_t_c_/_i_n_p_u_t_r_c: - - $$iinncclluuddee _/_e_t_c_/_i_n_p_u_t_r_c - -SSEEAARRCCHHIINNGG - Readline provides commands for searching through the com- - mand history for lines containing a specified string. - There are two search modes: _i_n_c_r_e_m_e_n_t_a_l and _n_o_n_-_i_n_c_r_e_m_e_n_- - _t_a_l. - - 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 his- - tory for a particular string, type CC--rr. Typing CC--ss - searches forward through the history. The characters pre- - sent in the value of the iisseeaarrcchh--tteerrmmiinnaattoorrss variable are - used to terminate an incremental search. If that variable - has not been assigned a value the _E_s_c_a_p_e and CC--JJ charac- - ters will terminate an incremental search. CC--GG 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 - CC--ss or CC--rr 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 exe- - cute that command. For instance, a newline will terminate - the search and accept the line, thereby executing the com- - mand from the history list. A movement command will ter- - minate the search, make the last line found the current - line, and begin editing. - - 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. - -EEDDIITTIINNGG CCOOMMMMAANNDDSS - The following is a list of the names of the commands and - the default key sequences to which they are bound. Com- - mand names without an accompanying key sequence are - unbound by default. - - In the following descriptions, _p_o_i_n_t refers to the current - cursor position, and _m_a_r_k refers to a cursor position - saved by the sseett--mmaarrkk command. The text between the point - and mark is referred to as the _r_e_g_i_o_n. - - CCoommmmaannddss ffoorr MMoovviinngg - bbeeggiinnnniinngg--ooff--lliinnee ((CC--aa)) - Move to the start of the current line. - eenndd--ooff--lliinnee ((CC--ee)) - Move to the end of the line. - ffoorrwwaarrdd--cchhaarr ((CC--ff)) - Move forward a character. - bbaacckkwwaarrdd--cchhaarr ((CC--bb)) - Move back a character. - ffoorrwwaarrdd--wwoorrdd ((MM--ff)) - Move forward to the end of the next word. Words - are composed of alphanumeric characters (letters - and digits). - bbaacckkwwaarrdd--wwoorrdd ((MM--bb)) - Move back to the start of the current or previous - word. Words are composed of alphanumeric charac- - ters (letters and digits). - cclleeaarr--ssccrreeeenn ((CC--ll)) - Clear the screen leaving the current line at the - top of the screen. With an argument, refresh the - current line without clearing the screen. - rreeddrraaww--ccuurrrreenntt--lliinnee - Refresh the current line. - - CCoommmmaannddss ffoorr MMaanniippuullaattiinngg tthhee HHiissttoorryy - aacccceepptt--lliinnee ((NNeewwlliinnee,, RReettuurrnn)) - 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 aadddd__hhiissttoorryy(()). - If the line is a modified history line, the history - line is restored to its original state. - pprreevviioouuss--hhiissttoorryy ((CC--pp)) - Fetch the previous command from the history list, - moving back in the list. - nneexxtt--hhiissttoorryy ((CC--nn)) - Fetch the next command from the history list, mov- - ing forward in the list. - bbeeggiinnnniinngg--ooff--hhiissttoorryy ((MM--<<)) - Move to the first line in the history. - eenndd--ooff--hhiissttoorryy ((MM-->>)) - Move to the end of the input history, i.e., the - line currently being entered. - rreevveerrssee--sseeaarrcchh--hhiissttoorryy ((CC--rr)) - Search backward starting at the current line and - moving `up' through the history as necessary. This - is an incremental search. - ffoorrwwaarrdd--sseeaarrcchh--hhiissttoorryy ((CC--ss)) - Search forward starting at the current line and - moving `down' through the history as necessary. - This is an incremental search. - nnoonn--iinnccrreemmeennttaall--rreevveerrssee--sseeaarrcchh--hhiissttoorryy ((MM--pp)) - Search backward through the history starting at the - current line using a non-incremental search for a - string supplied by the user. - nnoonn--iinnccrreemmeennttaall--ffoorrwwaarrdd--sseeaarrcchh--hhiissttoorryy ((MM--nn)) - Search forward through the history using a non- - incremental search for a string supplied by the - user. - hhiissttoorryy--sseeaarrcchh--ffoorrwwaarrdd - Search forward through the history for the string - of characters between the start of the current line - and the current cursor position (the _p_o_i_n_t). This - is a non-incremental search. - hhiissttoorryy--sseeaarrcchh--bbaacckkwwaarrdd - Search backward through the history for the string - of characters between the start of the current line - and the point. This is a non-incremental search. - yyaannkk--nntthh--aarrgg ((MM--CC--yy)) - Insert the first argument to the previous command - (usually the second word on the previous line) at - point. With an argument _n, insert the _nth word - from the previous command (the words in the previ- - ous command begin with word 0). A negative argu- - ment inserts the _nth word from the end of the pre- - vious command. - yyaannkk--llaasstt--aarrgg ((MM--..,, MM--__)) - Insert the last argument to the previous command - (the last word of the previous history entry). - With an argument, behave exactly like yyaannkk--nntthh--aarrgg. - Successive calls to yyaannkk--llaasstt--aarrgg move back through - the history list, inserting the last argument of - each line in turn. - - CCoommmmaannddss ffoorr CChhaannggiinngg TTeexxtt - ddeelleettee--cchhaarr ((CC--dd)) - Delete the character at point. If point is at the - beginning of the line, there are no characters in - the line, and the last character typed was not - bound to ddeelleettee--cchhaarr, then return EEOOFF. - bbaacckkwwaarrdd--ddeelleettee--cchhaarr ((RRuubboouutt)) - Delete the character behind the cursor. When given - a numeric argument, save the deleted text on the - kill ring. - ffoorrwwaarrdd--bbaacckkwwaarrdd--ddeelleettee--cchhaarr - Delete the character under the cursor, unless the - cursor is at the end of the line, in which case the - character behind the cursor is deleted. - qquuootteedd--iinnsseerrtt ((CC--qq,, CC--vv)) - Add the next character that you type to the line - verbatim. This is how to insert characters like - CC--qq, for example. - ttaabb--iinnsseerrtt ((MM--TTAABB)) - Insert a tab character. - sseellff--iinnsseerrtt ((aa,, bb,, AA,, 11,, !!,, ......)) - Insert the character typed. - ttrraannssppoossee--cchhaarrss ((CC--tt)) - Drag the character before point forward over the - character at point, moving point forward as well. - If point is at the end of the line, then this - transposes the two characters before point. Nega- - tive arguments have no effect. - ttrraannssppoossee--wwoorrddss ((MM--tt)) - Drag the word before point past the word after - point, moving point over that word as well. If - point is at the end of the line, this transposes - the last two words on the line. - uuppccaassee--wwoorrdd ((MM--uu)) - Uppercase the current (or following) word. With a - negative argument, uppercase the previous word, but - do not move point. - ddoowwnnccaassee--wwoorrdd ((MM--ll)) - Lowercase the current (or following) word. With a - negative argument, lowercase the previous word, but - do not move point. - ccaappiittaalliizzee--wwoorrdd ((MM--cc)) - Capitalize the current (or following) word. With a - negative argument, capitalize the previous word, - but do not move point. - oovveerrwwrriittee--mmooddee - Toggle overwrite mode. With an explicit positive - numeric argument, switches to overwrite mode. With - an explicit non-positive numeric argument, switches - to insert mode. This command affects only eemmaaccss - mode; vvii mode does overwrite differently. Each - call to _r_e_a_d_l_i_n_e_(_) starts in insert mode. In over- - write mode, characters bound to sseellff--iinnsseerrtt replace - the text at point rather than pushing the text to - the right. Characters bound to bbaacckk-- - wwaarrdd--ddeelleettee--cchhaarr replace the character before point - with a space. By default, this command is unbound. - - KKiilllliinngg aanndd YYaannkkiinngg - kkiillll--lliinnee ((CC--kk)) - Kill the text from point to the end of the line. - bbaacckkwwaarrdd--kkiillll--lliinnee ((CC--xx RRuubboouutt)) - Kill backward to the beginning of the line. - uunniixx--lliinnee--ddiissccaarrdd ((CC--uu)) - Kill backward from point to the beginning of the - line. The killed text is saved on the kill-ring. - kkiillll--wwhhoollee--lliinnee - Kill all characters on the current line, no matter - where point is. - kkiillll--wwoorrdd ((MM--dd)) - Kill from point 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 ffoorr-- - wwaarrdd--wwoorrdd. - bbaacckkwwaarrdd--kkiillll--wwoorrdd ((MM--RRuubboouutt)) - Kill the word behind point. Word boundaries are - the same as those used by bbaacckkwwaarrdd--wwoorrdd. - uunniixx--wwoorrdd--rruubboouutt ((CC--ww)) - Kill the word behind point, using white space as a - word boundary. The killed text is saved on the - kill-ring. - ddeelleettee--hhoorriizzoonnttaall--ssppaaccee ((MM--\\)) - Delete all spaces and tabs around point. - kkiillll--rreeggiioonn - Kill the text between the point and _m_a_r_k (saved - cursor position). This text is referred to as the - _r_e_g_i_o_n. - ccooppyy--rreeggiioonn--aass--kkiillll - Copy the text in the region to the kill buffer. - ccooppyy--bbaacckkwwaarrdd--wwoorrdd - Copy the word before point to the kill buffer. The - word boundaries are the same as bbaacckkwwaarrdd--wwoorrdd. - ccooppyy--ffoorrwwaarrdd--wwoorrdd - Copy the word following point to the kill buffer. - The word boundaries are the same as ffoorrwwaarrdd--wwoorrdd. - yyaannkk ((CC--yy)) - Yank the top of the kill ring into the buffer at - point. - yyaannkk--ppoopp ((MM--yy)) - Rotate the kill ring, and yank the new top. Only - works following yyaannkk or yyaannkk--ppoopp. - - NNuummeerriicc AArrgguummeennttss - ddiiggiitt--aarrgguummeenntt ((MM--00,, MM--11,, ......,, MM----)) - Add this digit to the argument already accumulat- - ing, or start a new argument. M-- starts a nega- - tive argument. - uunniivveerrssaall--aarrgguummeenntt - This is another way to specify an argument. If - this command is followed by one or more digits, - optionally with a leading minus sign, those digits - define the argument. If the command is followed by - digits, executing uunniivveerrssaall--aarrgguummeenntt again ends the - numeric argument, but is otherwise ignored. As a - special case, if this command is immediately fol- - lowed by a character that is neither a digit or - minus sign, the argument count for the next command - is multiplied by four. The argument count is ini- - tially one, so executing this function the first - time makes the argument count four, a second time - makes the argument count sixteen, and so on. - - CCoommpplleettiinngg - ccoommpplleettee ((TTAABB)) - Attempt to perform completion on the text before - point. The actual completion performed is applica- - tion-specific. BBaasshh, for instance, attempts com- - pletion treating the text as a variable (if the - text begins with $$), username (if the text begins - with ~~), hostname (if the text begins with @@), or - command (including aliases and functions) in turn. - If none of these produces a match, filename comple- - tion is attempted. GGddbb, on the other hand, allows - completion of program functions and variables, and - only attempts filename completion under certain - circumstances. - ppoossssiibbllee--ccoommpplleettiioonnss ((MM--??)) - List the possible completions of the text before - point. - iinnsseerrtt--ccoommpplleettiioonnss ((MM--**)) - Insert all completions of the text before point - that would have been generated by ppoossssiibbllee--ccoommppllee-- - ttiioonnss. - mmeennuu--ccoommpplleettee - Similar to ccoommpplleettee, but replaces the word to be - completed with a single match from the list of pos- - sible completions. Repeated execution of mmeennuu--ccoomm-- - pplleettee steps through the list of possible comple- - tions, inserting each match in turn.

If -.B prompt -is \fBNULL\fP or the empty string, no prompt is issued. -The line returned is allocated with -.IR malloc (3); -the caller must free it when finished. The line returned -has the final newline removed, so only the text of the line -remains. -.LP -.B readline -offers editing capabilities while the user is entering the -line. -By default, the line editing commands -are similar to those of emacs. -A vi\-style line editing interface is also available. -.LP -This manual page describes only the most basic use of \fBreadline\fP. -Much more functionality is available; see -\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP -for additional information. -.SH RETURN VALUE -.LP -.B readline -returns the text of the line read. A blank line -returns the empty string. If -.B EOF -is encountered while reading a line, and the line is empty, -.B NULL -is returned. If an -.B EOF -is read with a non\-empty line, it is -treated as a newline. -.SH NOTATION -.LP -An emacs-style notation is used to denote -keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n -means Control\-N. Similarly, -.I meta -keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards -without a -.I meta -key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key -then the -.I x -key. This makes ESC the \fImeta prefix\fP. -The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, -or press the Escape key -then hold the Control key while pressing the -.I x -key.) -.PP -Readline commands may be given numeric -.IR arguments , -which normally act as a repeat count. Sometimes, however, it is the -sign of the argument that is significant. Passing a negative argument -to a command that acts in the forward direction (e.g., \fBkill\-line\fP) -causes that command to act in a backward direction. Commands whose -behavior with arguments deviates from this are noted. -.PP -When a command is described as \fIkilling\fP text, the text -deleted is saved for possible future retrieval -(\fIyanking\fP). The killed text is saved in a -\fIkill ring\fP. Consecutive kills cause the text to be -accumulated into one unit, which can be yanked all at once. -Commands which do not kill text separate the chunks of text -on the kill ring. -.SH INITIALIZATION FILE -.LP -Readline is customized by putting commands in an initialization -file (the \fIinputrc\fP file). -The name of this file is taken from the value of the -.B INPUTRC -environment variable. If that variable is unset, the default is -.IR ~/.inputrc . -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. -.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). -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 comment\-begin (``#'') -The string that is inserted in \fBvi\fP mode when the -.B insert\-comment -command is executed. -This command is bound to -.B M\-# -in emacs mode and to -.B # -in vi command mode. -.TP -.B completion\-ignore\-case (Off) -If set to \fBOn\fP, readline performs filename matching and completion -in a case\-insensitive fashion. -.TP -.B completion\-query\-items (100) -This determines when the user is queried about viewing -the number of possible completions -generated by the \fBpossible\-completions\fP command. -It may be set to any integer value greater than or equal to -zero. If the number of possible completions is greater than -or equal to the value of this variable, the user is asked whether -or not he wishes to view them; otherwise they are simply listed -on the terminal. -.TP -.B convert\-meta (On) -If set to \fBOn\fP, readline will convert characters with the -eighth bit set to an ASCII key sequence -by stripping the eighth bit and prefixing it with an -escape character (in effect, using escape as the \fImeta prefix\fP). -.TP -.B disable\-completion (Off) -If set to \fBOn\fP, readline will inhibit word completion. Completion -characters will be inserted into the line as if they had been -mapped to \fBself-insert\fP. -.TP -.B editing\-mode (emacs) -Controls whether readline begins with a set of key bindings similar -to emacs or vi. -.B editing\-mode -can be set to either -.B emacs -or -.BR vi . -.TP -.B enable\-keypad (Off) -When set to \fBOn\fP, readline will try to enable the application -keypad when it is called. Some systems need this to enable the -arrow keys. -.TP -.B expand\-tilde (Off) -If set to \fBon\fP, tilde expansion is performed when readline -attempts word completion. -.TP -.B history-preserve-point -If set to \fBon\fP, the history code attempts to place point at the -same location on each history line retrived with \fBprevious-history\fP -or \fBnext-history\fP. -.TP -.B horizontal\-scroll\-mode (Off) -When set to \fBOn\fP, makes readline use a single line for display, -scrolling the input horizontally on a single screen line when it -becomes longer than the screen width rather than wrapping to a new line. -.TP -.B input\-meta (Off) -If set to \fBOn\fP, readline will enable eight-bit input (that is, -it will not clear the eighth bit in the characters it reads), -regardless of what the terminal claims it can support. The name -.B meta\-flag -is a synonym for this variable. -.TP -.B isearch\-terminators (``C\-[ C\-J'') -The string of characters that should terminate an incremental -search without subsequently executing the character as a command. -If this variable has not been given a value, the characters -\fIESC\fP and \fIC\-J\fP will terminate an incremental search. -.TP -.B keymap (emacs) -Set the current readline keymap. The set of legal keymap names is -\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, -vi-command\fP, and -.IR vi-insert . -\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is -equivalent to \fIemacs-standard\fP. The default value is -.IR emacs . -The value of -.B editing\-mode -also affects the default keymap. -.TP -.B mark\-directories (On) -If set to \fBOn\fP, completed directory names have a slash -appended. -.TP -.B mark\-modified\-lines (Off) -If set to \fBOn\fP, history lines that have been modified are displayed -with a preceding asterisk (\fB*\fP). -.TP -.B mark\-symlinked\-directories (Off) -If set to \fBOn\fP, completed names which are symbolic links to directories -have a slash appended (subject to the value of -\fBmark\-directories\fP). -.TP -.B match\-hidden\-files (On) -This variable, when set to \fBOn\fP, causes readline to match files whose -names begin with a `.' (hidden files) when performing filename -completion, unless the leading `.' is -supplied by the user in the filename to be completed. -.TP -.B output\-meta (Off) -If set to \fBOn\fP, readline will display characters with the -eighth bit set directly rather than as a meta-prefixed escape -sequence. -.TP -.B page\-completions (On) -If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager -to display a screenful of possible completions at a time. -.TP -.B print\-completions\-horizontally (Off) -If set to \fBOn\fP, readline will display completions with matches -sorted horizontally in alphabetical order, rather than down the screen. -.TP -.B show\-all\-if\-ambiguous (Off) -This alters the default behavior of the completion functions. If -set to -.BR on , -words which have more than one possible completion cause the -matches to be listed immediately instead of ringing the bell. -.TP -.B visible\-stats (Off) -If set to \fBOn\fP, a character denoting a file's type as reported -by \fIstat\fP(2) is appended to the filename when listing possible -completions. -.PD -.SS Conditional Constructs -.PP -Readline implements a facility similar in spirit to the conditional -compilation features of the C preprocessor which allows key -bindings and variable settings to be performed as the result -of tests. There are four parser directives used. -.IP \fB$if\fP -The -.B $if -construct allows bindings to be made based on the -editing mode, the terminal being used, or the application using -readline. The text of the test extends to the end of the line; -no characters are required to isolate it. -.RS -.IP \fBmode\fP -The \fBmode=\fP form of the \fB$if\fP directive is used to test -whether readline is in emacs or vi mode. -This may be used in conjunction -with the \fBset keymap\fP command, for instance, to set bindings in -the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if -readline is starting out in emacs mode. -.IP \fBterm\fP -The \fBterm=\fP form may be used to include terminal-specific -key bindings, perhaps to bind the key sequences output by the -terminal's function keys. The word on the right side of the -.B = -is tested against the full name of the terminal and the portion -of the terminal name before the first \fB\-\fP. This allows -.I sun -to match both -.I sun -and -.IR sun\-cmd , -for instance. -.IP \fBapplication\fP -The \fBapplication\fP construct is used to include -application-specific settings. Each program using the readline -library sets the \fIapplication name\fP, and an initialization -file can test for a particular value. -This could be used to bind key sequences to functions useful for -a specific program. For instance, the following command adds a -key sequence that quotes the current or previous word in Bash: -.sp 1 -.RS -.nf -\fB$if\fP Bash -# Quote the current or previous word -"\eC-xq": "\eeb\e"\eef\e"" -\fB$endif\fP -.fi -.RE -.RE -.IP \fB$endif\fP -This command, as seen in the previous example, terminates an -\fB$if\fP command. -.IP \fB$else\fP -Commands in this branch of the \fB$if\fP directive are executed if -the test fails. -.IP \fB$include\fP -This directive takes a single filename as an argument and reads commands -and bindings from that file. For example, the following directive -would read \fI/etc/inputrc\fP: -.sp 1 -.RS -.nf -\fB$include\fP \^ \fI/etc/inputrc\fP -.fi -.RE -.SH SEARCHING -.PP -Readline provides commands for searching through the command history -for lines containing a specified string. -There are two search modes: -.I incremental -and -.IR non-incremental . -.PP -Incremental searches begin before the user has finished typing the -search string. -As each character of the search string is typed, readline displays -the next entry from the history matching the string typed so far. -An incremental search requires only as many characters as needed to -find the desired history entry. -To search backward in the history for a particular string, type -\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history. -The characters present in the value of the \fBisearch-terminators\fP -variable are used to terminate an incremental search. -If that variable has not been assigned a value the \fIEscape\fP and -\fBC\-J\fP characters will terminate an incremental search. -\fBC\-G\fP will abort an incremental search and restore the original -line. -When the search is terminated, the history entry containing the -search string becomes the current line. -.PP -To find other matching entries in the history list, type \fBC\-s\fP or -\fBC\-r\fP as appropriate. -This will search backward or forward in the history for the next -line matching the search string typed so far. -Any other key sequence bound to a readline command will terminate -the search and execute that command. -For instance, a newline will terminate the search and accept -the line, thereby executing the command from the history list. -A movement command will terminate the search, make the last line found -the current line, and begin editing. -.PP -Non-incremental searches read the entire search string before starting -to search for matching history lines. The search string may be -typed by the user or be part of the contents of the current line. -.SH EDITING COMMANDS -.PP -The following is a list of the names of the commands and the default -key sequences to which they are bound. -Command names without an accompanying key sequence are unbound by default. -.PP -In the following descriptions, \fIpoint\fP refers to the current cursor -position, and \fImark\fP refers to a cursor position saved by the -\fBset\-mark\fP command. -The text between the point and mark is referred to as the \fIregion\fP. -.SS Commands for Moving -.PP -.PD 0 -.TP -.B beginning\-of\-line (C\-a) -Move to the start of the current line. -.TP -.B end\-of\-line (C\-e) -Move to the end of the line. -.TP -.B forward\-char (C\-f) -Move forward a character. -.TP -.B backward\-char (C\-b) -Move back a character. -.TP -.B forward\-word (M\-f) -Move forward to the end of the next word. Words are composed of -alphanumeric characters (letters and digits). -.TP -.B backward\-word (M\-b) -Move back to the start of the current or previous word. Words are -composed of alphanumeric characters (letters and digits). -.TP -.B clear\-screen (C\-l) -Clear the screen leaving the current line at the top of the screen. -With an argument, refresh the current line without clearing the -screen. -.TP -.B redraw\-current\-line -Refresh the current line. -.PD -.SS Commands for Manipulating the History -.PP -.PD 0 -.TP -.B accept\-line (Newline, Return) -Accept the line regardless of where the cursor is. -If this line is -non-empty, it may be added to the history list for future recall with -\fBadd_history()\fP. -If the line is a modified history line, the history line is restored to its original state. -.TP -.B previous\-history (C\-p) -Fetch the previous command from the history list, moving back in -the list. -.TP -.B next\-history (C\-n) -Fetch the next command from the history list, moving forward in the -list. -.TP -.B beginning\-of\-history (M\-<) -Move to the first line in the history. -.TP -.B end\-of\-history (M\->) -Move to the end of the input history, i.e., the line currently being -entered. -.TP -.B reverse\-search\-history (C\-r) -Search backward starting at the current line and moving `up' through -the history as necessary. This is an incremental search. -.TP -.B forward\-search\-history (C\-s) -Search forward starting at the current line and moving `down' through -the history as necessary. This is an incremental search. -.TP -.B non\-incremental\-reverse\-search\-history (M\-p) -Search backward through the history starting at the current line -using a non-incremental search for a string supplied by the user. -.TP -.B non\-incremental\-forward\-search\-history (M\-n) -Search forward through the history using a non-incremental search -for a string supplied by the user. -.TP -.B history\-search\-forward -Search forward through the history for the string of characters -between the start of the current line and the current cursor -position (the \fIpoint\fP). -This is a non-incremental search. -.TP -.B history\-search\-backward -Search backward through the history for the string of characters -between the start of the current line and the point. -This is a non-incremental search. -.TP -.B yank\-nth\-arg (M\-C\-y) -Insert the first argument to the previous command (usually -the second word on the previous line) at point. -With an argument -.IR n , -insert the \fIn\fPth word from the previous command (the words -in the previous command begin with word 0). A negative argument -inserts the \fIn\fPth word from the end of the previous command. -.TP -.B -yank\-last\-arg (M\-.\^, M\-_\^) -Insert the last argument to the previous command (the last word of -the previous history entry). With an argument, -behave exactly like \fByank\-nth\-arg\fP. -Successive calls to \fByank\-last\-arg\fP move back through the history -list, inserting the last argument of each line in turn. -.PD -.SS Commands for Changing Text -.PP -.PD 0 -.TP -.B delete\-char (C\-d) -Delete the character at point. If point is at the -beginning of the line, there are no characters in the line, and -the last character typed was not bound to \fBdelete\-char\fP, then return -.SM -.BR EOF . -.TP -.B backward\-delete\-char (Rubout) -Delete the character behind the cursor. When given a numeric argument, -save the deleted text on the kill ring. -.TP -.B forward\-backward\-delete\-char -Delete the character under the cursor, unless the cursor is at the -end of the line, in which case the character behind the cursor is -deleted. -.TP -.B quoted\-insert (C\-q, C\-v) -Add the next character that you type to the line verbatim. This is -how to insert characters like \fBC\-q\fP, for example. -.TP -.B tab\-insert (M-TAB) -Insert a tab character. -.TP -.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...) -Insert the character typed. -.TP -.B transpose\-chars (C\-t) -Drag the character before point forward over the character at point, -moving point forward as well. -If point is at the end of the line, then this transposes -the two characters before point. -Negative arguments have no effect. -.TP -.B transpose\-words (M\-t) -Drag the word before point past the word after point, -moving point over that word as well. -If point is at the end of the line, this transposes -the last two words on the line. -.TP -.B upcase\-word (M\-u) -Uppercase the current (or following) word. With a negative argument, -uppercase the previous word, but do not move point. -.TP -.B downcase\-word (M\-l) -Lowercase the current (or following) word. With a negative argument, -lowercase the previous word, but do not move point. -.TP -.B capitalize\-word (M\-c) -Capitalize the current (or following) word. With a negative argument, -capitalize the previous word, but do not move point. -.TP -.B overwrite\-mode -Toggle overwrite mode. With an explicit positive numeric argument, -switches to overwrite mode. With an explicit non-positive numeric -argument, switches to insert mode. This command affects only -\fBemacs\fP mode; \fBvi\fP mode does overwrite differently. -Each call to \fIreadline()\fP starts in insert mode. -In overwrite mode, characters bound to \fBself\-insert\fP replace -the text at point rather than pushing the text to the right. -Characters bound to \fBbackward\-delete\-char\fP replace the character -before point with a space. By default, this command is unbound. -.PD -.SS Killing and Yanking -.PP -.PD 0 -.TP -.B kill\-line (C\-k) -Kill the text from point to the end of the line. -.TP -.B backward\-kill\-line (C\-x Rubout) -Kill backward to the beginning of the line. -.TP -.B unix\-line\-discard (C\-u) -Kill backward from point to the beginning of the line. -The killed text is saved on the kill-ring. -.\" There is no real difference between this and backward-kill-line -.TP -.B kill\-whole\-line -Kill all characters on the current line, no matter where point is. -.TP -.B kill\-word (M\-d) -Kill from point 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 \fBforward\-word\fP. -.TP -.B backward\-kill\-word (M\-Rubout) -Kill the word behind point. -Word boundaries are the same as those used by \fBbackward\-word\fP. -.TP -.B unix\-word\-rubout (C\-w) -Kill the word behind point, using white space as a word boundary. -The killed text is saved on the kill-ring. -.TP -.B delete\-horizontal\-space (M\-\e) -Delete all spaces and tabs around point. -.TP -.B kill\-region -Kill the text between the point and \fImark\fP (saved cursor position). -This text is referred to as the \fIregion\fP. -.TP -.B copy\-region\-as\-kill -Copy the text in the region to the kill buffer. -.TP -.B copy\-backward\-word -Copy the word before point to the kill buffer. -The word boundaries are the same as \fBbackward\-word\fP. -.TP -.B copy\-forward\-word -Copy the word following point to the kill buffer. -The word boundaries are the same as \fBforward\-word\fP. -.TP -.B yank (C\-y) -Yank the top of the kill ring into the buffer at point. -.TP -.B yank\-pop (M\-y) -Rotate the kill ring, and yank the new top. Only works following -.B yank -or -.BR yank\-pop . -.PD -.SS Numeric Arguments -.PP -.PD 0 -.TP -.B digit\-argument (M\-0, M\-1, ..., M\-\-) -Add this digit to the argument already accumulating, or start a new -argument. M\-\- starts a negative argument. -.TP -.B universal\-argument -This is another way to specify an argument. -If this command is followed by one or more digits, optionally with a -leading minus sign, those digits define the argument. -If the command is followed by digits, executing -.B universal\-argument -again ends the numeric argument, but is otherwise ignored. -As a special case, if this command is immediately followed by a -character that is neither a digit or minus sign, the argument count -for the next command is multiplied by four. -The argument count is initially one, so executing this function the -first time makes the argument count four, a second time makes the -argument count sixteen, and so on. -.PD -.SS Completing -.PP -.PD 0 -.TP -.B complete (TAB) -Attempt to perform completion on the text before point. -The actual completion performed is application-specific. -.BR Bash , -for instance, attempts completion treating the text as a variable -(if the text begins with \fB$\fP), username (if the text begins with -\fB~\fP), hostname (if the text begins with \fB@\fP), or -command (including aliases and functions) in turn. If none -of these produces a match, filename completion is attempted. -.BR Gdb , -on the other hand, -allows completion of program functions and variables, and -only attempts filename completion under certain circumstances. -.TP -.B possible\-completions (M\-?) -List the possible completions of the text before point. -.TP -.B insert\-completions (M\-*) -Insert all completions of the text before point -that would have been generated by -\fBpossible\-completions\fP. -.TP -.B menu\-complete -Similar to \fBcomplete\fP, but replaces the word to be completed -with a single match from the list of possible completions. -Repeated execution of \fBmenu\-complete\fP steps through the list -of possible completions, inserting each match in turn. -At the end of the list of completions, the bell is rung -(subject to the setting of \Bbell\-style\fP) -and the original text is restored. -An argument of \fIn\fP moves \fIn\fP positions forward in the list -of matches; a negative argument may be used to move backward -through the list. -This command is intended to be bound to \fBTAB\fP, but is unbound -by default. -.TP -.B delete\-char\-or\-list -Deletes the character under the cursor if not at the beginning or -end of the line (like \fBdelete-char\fP). -If at the end of the line, behaves identically to -\fBpossible-completions\fP. -.PD -.SS Keyboard Macros -.PP -.PD 0 -.TP -.B start\-kbd\-macro (C\-x (\^) -Begin saving the characters typed into the current keyboard macro. -.TP -.B end\-kbd\-macro (C\-x )\^) -Stop saving the characters typed into the current keyboard macro -and store the definition. -.TP -.B call\-last\-kbd\-macro (C\-x e) -Re-execute the last keyboard macro defined, by making the characters -in the macro appear as if typed at the keyboard. -.PD -.SS Miscellaneous -.PP -.PD 0 -.TP -.B re\-read\-init\-file (C\-x C\-r) -Read in the contents of the \fIinputrc\fP file, and incorporate -any bindings or variable assignments found there. -.TP -.B abort (C\-g) -Abort the current editing command and -ring the terminal's bell (subject to the setting of -.BR bell\-style ). -.TP -.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...) -If the metafied character \fIx\fP is lowercase, run the command -that is bound to the corresponding uppercase character. -.TP -.B prefix\-meta (ESC) -Metafy the next character typed. -.SM -.B ESC -.B f -is equivalent to -.BR Meta\-f . -.TP -.B undo (C\-_, C\-x C\-u) -Incremental undo, separately remembered for each line. -.TP -.B revert\-line (M\-r) -Undo all changes made to this line. This is like executing the -.B undo -command enough times to return the line to its initial state. -.TP -.B tilde\-expand (M\-&) -Perform tilde expansion on the current word. -.TP -.B set\-mark (C\-@, M\-<space>) -Set the mark to the point. If a -numeric argument is supplied, the mark is set to that position. -.TP -.B exchange\-point\-and\-mark (C\-x C\-x) -Swap the point with the mark. The current cursor position is set to -the saved position, and the old cursor position is saved as the mark. -.TP -.B character\-search (C\-]) -A character is read and point is moved to the next occurrence of that -character. A negative count searches for previous occurrences. -.TP -.B character\-search\-backward (M\-C\-]) -A character is read and point is moved to the previous occurrence of that -character. A negative count searches for subsequent occurrences. -.TP -.B insert\-comment (M\-#) -Without a numeric argument, the value of the readline -.B comment\-begin -variable is inserted at the beginning of the current line. -If a numeric argument is supplied, this command acts as a toggle: if -the characters at the beginning of the line do not match the value -of \fBcomment\-begin\fP, the value is inserted, otherwise -the characters in \fBcomment-begin\fP are deleted from the beginning of -the line. -In either case, the line is accepted as if a newline had been typed. -The default value of -.B comment\-begin -makes the current line a shell comment. -If a numeric argument causes the comment character to be removed, the line -will be executed by the shell. -.TP -.B dump\-functions -Print all of the functions and their key bindings to the -readline output stream. If a numeric argument is supplied, -the output is formatted in such a way that it can be made part -of an \fIinputrc\fP file. -.TP -.B dump\-variables -Print all of the settable variables and their values to the -readline output stream. If a numeric argument is supplied, -the output is formatted in such a way that it can be made part -of an \fIinputrc\fP file. -.TP -.B dump\-macros -Print all of the readline key sequences bound to macros and the -strings they ouput. If a numeric argument is supplied, -the output is formatted in such a way that it can be made part -of an \fIinputrc\fP file. -.TP -.B emacs\-editing\-mode (C\-e) -When in -.B vi -command mode, this causes a switch to -.B emacs -editing mode. -.TP -.B vi\-editing\-mode (M\-C\-j) -When in -.B emacs -editing mode, this causes a switch to -.B vi -editing mode. -.PD -.SH DEFAULT KEY BINDINGS -.LP -The following is a list of the default emacs and vi bindings. -Characters with the eighth bit set are written as M\-<character>, and -are referred to as -.I metafied -characters. -The printable ASCII characters not mentioned in the list of emacs -standard bindings are bound to the -.B self\-insert -function, which just inserts the given character into the input line. -In vi insertion mode, all

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 <RET>. You do not have to be at the end of -the line to press <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. - - -File: readline.info, Node: Readline Bare Essentials, Next: Readline Movement Commands, Up: Readline Interaction - -Readline Bare Essentials ------------------------- - - 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 `C-b' to move the cursor to the left, and then correct your -mistake. Afterwards, you can move the cursor to the right with `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. - -`C-b' - Move back one character. - -`C-f' - Move forward one character. - -<DEL> or <Backspace> - Delete the character to the left of the cursor. - -`C-d' - Delete the character underneath the cursor. - -Printing characters - Insert the character into the line at the cursor. - -`C-_' or `C-x C-u' - Undo the last editing command. You can undo all the way back to an - empty line. - -(Depending on your configuration, the <Backspace> key be set to delete -the character to the left of the cursor and the <DEL> key set to delete -the character underneath the cursor, like `C-d', rather than the -character to the left of the cursor.) - - -File: readline.info, Node: Readline Movement Commands, Next: Readline Killing Commands, Prev: Readline Bare Essentials, Up: Readline Interaction - -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 `C-b', `C-f', `C-d', and -<DEL>. Here are some commands for moving more rapidly about the line. - -`C-a' - Move to the start of the line. - -`C-e' - Move to the end of the line. - -`M-f' - Move forward a word, where a word is composed of letters and - digits. - -`M-b' - Move backward a word. - -`C-l' - Clear the screen, reprinting the current line at the top. - - Notice how `C-f' moves forward a character, while `M-f' moves -forward a word. It is a loose convention that control keystrokes -operate on characters while meta keystrokes operate on words. - - -File: readline.info, Node: Readline Killing Commands, Next: Readline Arguments, Prev: Readline Movement Commands, Up: Readline Interaction - -Readline Killing Commands -------------------------- - - "Killing" text means to delete the text from the line, but to save -it away for later use, usually by "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 "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. - - Here is the list of commands for killing text. - -`C-k' - Kill the text from the current cursor position to the end of the - line. - -`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 `M-f'. - -`M-<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 `M-b'. - -`C-w' - Kill from the cursor to the previous whitespace. This is - different than `M-<DEL>' because the word boundaries differ. - - Here is how to "yank" the text back into the line. Yanking means to -copy the most-recently-killed text from the kill buffer. - -`C-y' - Yank the most recently killed text back into the buffer at the - cursor. - -`M-y' - Rotate the kill-ring, and yank the new top. You can only do this - if the prior command is `C-y' or `M-y'. - - -File: readline.info, Node: Readline Arguments, Next: Searching, Prev: Readline Killing Commands, Up: Readline Interaction - -Readline Arguments ------------------- - - You can pass numeric arguments to Readline commands. Sometimes the -argument acts as a repeat count, other times it is the 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 `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 (`-'), 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 `C-d' command an argument of 10, you could type `M-1 0 C-d', which -will delete the next ten characters on the input line. - - -File: readline.info, Node: Searching, Prev: Readline Arguments, Up: Readline Interaction - -Searching for Commands in the History -------------------------------------- - - Readline provides commands for searching through the command history -for lines containing a specified string. There are two search modes: -"incremental" and "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 `C-r'. Typing `C-s' searches -forward through the history. The characters present in the value of -the `isearch-terminators' variable are used to terminate an incremental -search. If that variable has not been assigned a value, the <ESC> and -`C-J' characters will terminate an incremental search. `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 `C-r' or -`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 <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 -`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. - - -File: readline.info, Node: Readline Init File, Next: Bindable Readline Commands, Prev: Readline Interaction, Up: Command Line Editing - -Readline Init File -================== - - 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 "inputrc" file, conventionally in his home -directory. The name of this file is taken from the value of the -environment variable `INPUTRC'. If that variable is unset, the default -is `~/.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 `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. - - -File: readline.info, Node: Readline Init File Syntax, Next: Conditional Init Constructs, Up: Readline Init File - -Readline Init File Syntax -------------------------- - - There are only a few basic constructs allowed in the Readline init -file. Blank lines are ignored. Lines beginning with a `#' are -comments. Lines beginning with a `$' indicate conditional constructs -(*note Conditional Init Constructs::). Other lines denote variable -settings and key bindings. - -Variable Settings - You can modify the run-time behavior of Readline by altering the - values of variables in Readline using the `set' command within the - init file. The syntax is simple: - - set VARIABLE VALUE - - Here, for example, is how to change from the default Emacs-like - key binding to use `vi' line editing commands: - - set editing-mode vi - - Variable names and values, where appropriate, are recognized - without regard to case. - - A great deal of run-time behavior is changeable with the following - variables. - - `bell-style' - Controls what happens when Readline wants to ring the - terminal bell. If set to `none', Readline never rings the - bell. If set to `visible', Readline uses a visible bell if - one is available. If set to `audible' (the default), - Readline attempts to ring the terminal's bell. - - `comment-begin' - The string to insert at the beginning of the line when the - `insert-comment' command is executed. The default value is - `"#"'. - - `completion-ignore-case' - If set to `on', Readline performs filename matching and - completion in a case-insensitive fashion. The default value - is `off'. - - `completion-query-items' - The number of possible completions that determines when the - user is asked whether he wants to see the list of - possibilities. 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. The default limit is `100'. - - `convert-meta' - If set to `on', Readline will convert characters with the - eighth bit set to an ASCII key sequence by stripping the - eighth bit and prefixing an <ESC> character, converting them - to a meta-prefixed key sequence. The default value is `on'. - - `disable-completion' - If set to `On', Readline will inhibit word completion. - Completion characters will be inserted into the line as if - they had been mapped to `self-insert'. The default is `off'. - - `editing-mode' - The `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 `emacs' or `vi'. - - `enable-keypad' - When set to `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 `off'. - - `expand-tilde' - If set to `on', tilde expansion is performed when Readline - attempts word completion. The default is `off'. - - If set to `on', the history code attempts to place point at - the same location on each history line retrived with - `previous-history' or `next-history'. - - `horizontal-scroll-mode' - This variable can be set to either `on' or `off'. Setting it - to `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 `off'. - - `input-meta' - If set to `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 `off'. The name `meta-flag' is a synonym - for this variable. - - `isearch-terminators' - The string of characters that should terminate an incremental - search without subsequently executing the character as a - command (*note Searching::). If this variable has not been - given a value, the characters <ESC> and `C-J' will terminate - an incremental search. - - `keymap' - Sets Readline's idea of the current keymap for key binding - commands. Acceptable `keymap' names are `emacs', - `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move', - `vi-command', and `vi-insert'. `vi' is equivalent to - `vi-command'; `emacs' is equivalent to `emacs-standard'. The - default value is `emacs'. The value of the `editing-mode' - variable also affects the default keymap. - - `mark-directories' - If set to `on', completed directory names have a slash - appended. The default is `on'. - - `mark-modified-lines' - This variable, when set to `on', causes Readline to display an - asterisk (`*') at the start of history lines which have been - modified. This variable is `off' by default. - - `mark-symlinked-directories' - If set to `on', completed names which are symbolic links to - directories have a slash appended (subject to the value of - `mark-directories'). The default is `off'. - - `match-hidden-files' - This variable, when set to `on', causes Readline to match - files whose names begin with a `.' (hidden files) when - performing filename completion, unless the leading `.' is - supplied by the user in the filename to be completed. This - variable is `on' by default. - - `output-meta' - If set to `on', Readline will display characters with the - eighth bit set directly rather than as a meta-prefixed escape - sequence. The default is `off'. - - `page-completions' - If set to `on', Readline uses an internal `more'-like pager - to display a screenful of possible completions at a time. - This variable is `on' by default. - - `print-completions-horizontally' - If set to `on', Readline will display completions with matches - sorted horizontally in alphabetical order, rather than down - the screen. The default is `off'. - - `show-all-if-ambiguous' - This alters the default behavior of the completion functions. - If set to `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 `off'. - - `visible-stats' - If set to `on', a character denoting a file's type is - appended to the filename when listing possible completions. - The default is `off'. - -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. 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 MACRO). - - KEYNAME: FUNCTION-NAME or MACRO - KEYNAME is the name of a key spelled out in English. For - example: - Control-u: universal-argument - Meta-Rubout: backward-kill-word - Control-o: "> output" - - In the above example, `C-u' is bound to the function - `universal-argument', `M-DEL' is bound to the function - `backward-kill-word', and `C-o' is bound to run the macro - expressed on the right hand side (that is, to insert the text - `> output' into the line). - - A number of symbolic character names are recognized while - processing this key binding syntax: DEL, ESC, ESCAPE, LFD, - NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB. - - "KEYSEQ": FUNCTION-NAME or MACRO - KEYSEQ differs from KEYNAME above in that strings denoting an - entire key sequence can be specified, by placing the key - sequence in double quotes. Some GNU Emacs style key escapes - can be used, as in the following example, but the special - character names are not recognized. - - "\C-u": universal-argument - "\C-x\C-r": re-read-init-file - "\e[11~": "Function Key 1" - - In the above example, `C-u' is again bound to the function - `universal-argument' (just as it was in the first example), - `C-x C-r' is bound to the function `re-read-init-file', and - `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function - Key 1'. - - The following GNU Emacs style escape sequences are available when - specifying key sequences: - - `\C-' - control prefix - - `\M-' - meta prefix - - `\e' - an escape character - - `\\' - backslash - - `\"' - <">, a double quotation mark - - `\'' - <'>, a single quote or apostrophe - - In addition to the GNU Emacs style escape sequences, a second set - of backslash escapes is available: - - `\a' - alert (bell) - - `\b' - backspace - - `\d' - delete - - `\f' - form feed - - `\n' - newline - - `\r' - carriage return - - `\t' - horizontal tab - - `\v' - vertical tab - - `\NNN' - the eight-bit character whose value is the octal value NNN - (one to three digits) - - `\xHH' - the eight-bit character whose value is the hexadecimal value - HH (one or two hex digits) - - When entering the text of a macro, single or double quotes must 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 `''. For example, - the following binding will make `C-x \' insert a single `\' into - the line: - "\C-x\\": "\\" - - -File: readline.info, Node: Conditional Init Constructs, Next: Sample Init File, Prev: Readline Init File Syntax, Up: Readline Init File - -Conditional Init Constructs ---------------------------- - - 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. - -`$if' - The `$if' construct allows bindings to be made based on the - editing mode, the terminal being used, or the application using - Readline. The text of the test extends to the end of the line; no - characters are required to isolate it. - - `mode' - The `mode=' form of the `$if' directive is used to test - whether Readline is in `emacs' or `vi' mode. This may be - used in conjunction with the `set keymap' command, for - instance, to set bindings in the `emacs-standard' and - `emacs-ctlx' keymaps only if Readline is starting out in - `emacs' mode. - - `term' - The `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 - `=' is tested against both the full name of the terminal and - the portion of the terminal name before the first `-'. This - allows `sun' to match both `sun' and `sun-cmd', for instance. - - `application' - The APPLICATION construct is used to include - application-specific settings. Each program using the - Readline library sets the 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: - $if Bash - # Quote the current or previous word - "\C-xq": "\eb\"\ef\"" - $endif - -`$endif' - This command, as seen in the previous example, terminates an `$if' - command. - -`$else' - Commands in this branch of the `$if' directive are executed if the - test fails. - -`$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 `/etc/inputrc': - $include /etc/inputrc - - -File: readline.info, Node: Sample Init File, Prev: Conditional Init Constructs, Up: Readline Init File - -Sample Init File ----------------- - - Here is an example of an INPUTRC file.

With an argument N, - insert the Nth word from the previous command (the words in the - previous command begin with word 0). A negative argument inserts - the Nth word from the end of the previous command. - -`yank-last-arg (M-. or M-_)' - Insert last argument to the previous command (the last word of the - previous history entry).

If the insertion - point is at the end of the line, then this transposes the last two - characters of the line. Negative arguments have no effect. - -`transpose-words (M-t)' - Drag the word before point past the word after point, moving point - past that word as well. If the insertion point is at the end of - the line, this transposes the last two words on the line. - -`upcase-word (M-u)' - Uppercase the current (or following) word. With a negative - argument, uppercase the previous word, but do not move the cursor. - -`downcase-word (M-l)' - Lowercase the current (or following) word.

With a negative - argument, capitalize the previous word, but do not move the cursor. - -`overwrite-mode ()' - Toggle overwrite mode. With an explicit positive numeric argument, - switches to overwrite mode. With an explicit non-positive numeric - argument, switches to insert mode. This command affects only - `emacs' mode; `vi' mode does overwrite differently. Each call to - `readline()' starts in insert mode. - - In overwrite mode, characters bound to `self-insert' replace the - text at point rather than pushing the text to the right. - Characters bound to `backward-delete-char' replace the character - before point with a space. - - By default, this command is unbound. - - -File: readline.info, Node: Commands For Killing, Next: Numeric Arguments, Prev: Commands For Text, Up: Bindable Readline Commands - -Killing And Yanking -------------------- - -`kill-line (C-k)' - Kill the text from point to the end of the line. - -`backward-kill-line (C-x Rubout)' - Kill backward to the beginning of the line. - -`unix-line-discard (C-u)' - Kill backward from the cursor to the beginning of the current line. - -`kill-whole-line ()' - Kill all characters on the current line, no matter where point is. - By default, this is unbound. - -`kill-word (M-d)' - Kill from point to the end of the current word, or if between - words, to the end of the next word.

If this command is - followed by one or more digits, optionally with a leading minus - sign, those digits define the argument. If the command is - followed by digits, executing `universal-argument' again ends the - numeric argument, but is otherwise ignored. As a special case, if - this command is immediately followed by a character that is - neither a digit or minus sign, the argument count for the next - command is multiplied by four. The argument count is initially - one, so executing this function the first time makes the argument - count four, a second time makes the argument count sixteen, and so - on.

If a numeric argument is supplied, the - mark is set to that position. - -`exchange-point-and-mark (C-x C-x)' - Swap the point with the mark. The current cursor position is set - to the saved position, and the old cursor position is saved as the - mark. - -`character-search (C-])' - A character is read and point is moved to the next occurrence of - that character. A negative count searches for previous - occurrences. - -`character-search-backward (M-C-])' - A character is read and point is moved to the previous occurrence - of that character. A negative count searches for subsequent - occurrences. - -`insert-comment (M-#)' - Without a numeric argument, the value of the `comment-begin' - variable is inserted at the beginning of the current line. If a - numeric argument is supplied, this command acts as a toggle: if - the characters at the beginning of the line do not match the value - of `comment-begin', the value is inserted, otherwise the - characters in `comment-begin' are deleted from the beginning of - the line. In either case, the line is accepted as if a newline - had been typed. - -`dump-functions ()' - Print all of the functions and their key bindings to the Readline - output stream.

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 -`gets()' or `fgets()'. - - The function `readline()' prints a prompt PROMPT and then reads and -returns a single line of text from the user. If PROMPT is `NULL' or -the empty string, no prompt is displayed. The line `readline' returns -is allocated with `malloc()'; the caller should `free()' the line when -it has finished with it. The declaration for `readline' in ANSI C is - - `char *readline (const char *PROMPT);' - -So, one might say - `char *line = readline ("Enter a line: ");' - -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 `readline' encounters an `EOF' while reading the line, and the -line is empty at that point, then `(char *)NULL' is returned. -Otherwise, the line is ended just as if a newline had been typed. - - If you want the user to be able to get at the line later, (with -<C-p> for example), you must call `add_history()' to save the line away -in a "history" list of such lines. - - `add_history (line)'; - -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 `gets()' library -function, and has the advantage of no static buffer to overflow: - - /* 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); - } - - This function gives the user the default behaviour of <TAB> -completion: completion on file names. If you do not want Readline to -complete on filenames, you can change the binding of the <TAB> key with -`rl_bind_key()'. - - `int rl_bind_key (int KEY, rl_command_func_t *FUNCTION);' - - `rl_bind_key()' takes two arguments: KEY is the character that you -want to bind, and FUNCTION is the address of the function to call when -KEY is pressed. Binding <TAB> to `rl_insert()' makes <TAB> insert -itself. `rl_bind_key()' returns non-zero if KEY is not a valid ASCII -character code (between 0 and 255). - - Thus, to disable the default <TAB> behavior, the following suffices: - `rl_bind_key ('\t', rl_insert);' - - This code should be executed once at the start of your program; you -might write a function called `initialize_readline()' which performs -this and other desired initializations, such as installing custom -completers (*note Custom Completers::). - - -File: readline.info, Node: Custom Functions, Next: Readline Variables, Prev: Basic Behavior, Up: Programming with GNU Readline - -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 `<readline/readline.h>' in any file that -uses Readline's features. Since some of the definitions in -`readline.h' use the `stdio' library, the file `<stdio.h>' should be -included before `readline.h'. - - `readline.h' defines a C preprocessor variable that should be -treated as an integer, `RL_READLINE_VERSION', which may be used to -conditionally compile application code depending on the installed -Readline version. The value is a hexadecimal encoding of the major and -minor version numbers of the library, of the form 0xMMMM. MM is the -two-digit major version number; MM is the two-digit minor version -number.

When - `rl_point' is at the end of the line, `rl_point' and `rl_end' are - equal. - - - Variable: int rl_mark - The MARK (saved position) in the current line. If set, the mark - and point define a _region_. - - - Variable: int rl_done - Setting this to a non-zero value causes Readline to return the - current line immediately. - - - Variable: int rl_num_chars_to_read - Setting this to a positive value before calling `readline()' causes - Readline to return after accepting that many characters, rather - than reading up to a character bound to `accept-line'. - - - Variable: int rl_pending_input - Setting this to a value makes it the next keystroke read. This is - a way to stuff a single character into the input stream. - - - Variable: int rl_dispatching - Set to a non-zero value if a function is being called from a key - binding; zero otherwise. Application functions can test this to - discover whether they were called directly or by Readline's - dispatching mechanism. - - - Variable: int rl_erase_empty_line - Setting this to a non-zero value causes Readline to completely - erase the current line, including any prompt, any time a newline - is typed as the only character on an otherwise-empty line. The - cursor is moved to the beginning of the newly-blank line. - - - Variable: char * rl_prompt - The prompt Readline uses. This is set from the argument to - `readline()', and should not be assigned to directly. The - `rl_set_prompt()' function (*note Redisplay::) may be used to - modify the prompt string after calling `readline()'. - - - Variable: int rl_already_prompted - If an application wishes to display the prompt itself, rather than - have Readline do it the first time `readline()' is called, it - should set this variable to a non-zero value after displaying the - prompt. The prompt must also be passed as the argument to - `readline()' so the redisplay functions can update the display - properly. The calling application is responsible for managing the - value; Readline never sets it. - - - Variable: const char * rl_library_version - The version number of this revision of the library. - - - Variable: int rl_readline_version - An integer encoding the current version of the library. The - encoding is of the form 0xMMMM, where MM is the two-digit major - version number, and MM is the two-digit minor version number. For - example, for Readline-4.2, `rl_readline_version' would have the - value 0x0402. - - - Variable: int rl_gnu_readline_p - Always set to 1, denoting that this is GNU readline rather than - some emulation. - - - Variable: const char * rl_terminal_name - The terminal type, used for initialization. If not set by the - application, Readline sets this to the value of the `TERM' - environment variable the first time it is called. - - - Variable: const char * rl_readline_name - This variable is set to a unique name by each application using - Readline. The value allows conditional parsing of the inputrc file - (*note Conditional Init Constructs::). - - - Variable: FILE * rl_instream - The stdio stream from which Readline reads input.

By default, this - will be called at most ten times a second if there is no keyboard - input. - - - Variable: rl_getc_func_t * rl_getc_function - If non-zero, Readline will call indirectly through this pointer to - get a character from the input stream. By default, it is set to - `rl_getc', the default Readline character input function (*note - Character Input::). - - - Variable: rl_voidfunc_t * rl_redisplay_function - If non-zero, Readline will call indirectly through this pointer to - update the display with the current contents of the editing buffer. - By default, it is set to `rl_redisplay', the default Readline - redisplay function (*note Redisplay::). - - - Variable: rl_vintfunc_t * rl_prep_term_function - If non-zero, Readline will call indirectly through this pointer to - initialize the terminal.

This function is - called by `readline()'. It may also be called to expand the - primary prompt if the `rl_on_new_line_with_prompt()' function or - `rl_already_prompted' variable is used. It returns the number of - visible characters on the last line of the (possibly multi-line) - prompt. - - - Function: int rl_set_prompt (const char *prompt) - Make Readline use PROMPT for subsequent redisplay.

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 (`SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', -`SIGTSTP', `SIGTTIN', and `SIGTTOU'). When one of these signals is -received, the signal handler will reset the terminal attributes to -those that were in effect before `readline()' was called, reset the -signal handling to what it was before `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 `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 -`rl_free_line_state()' below). - - There is an additional Readline signal handler, for `SIGWINCH', which -the kernel sends to a process whenever the terminal's size changes (for -example, if a user resizes an `xterm'). The Readline `SIGWINCH' -handler updates Readline's internal screen size information, and then -calls any `SIGWINCH' signal handler the calling application has -installed. Readline calls the application's `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 `longjmp' back to a main -processing loop), it _must_ call `rl_cleanup_after_signal()' (described -below), to restore the terminal state. - - Readline provides two variables that allow application writers to -control whether or not it will catch certain signals and act on them -when they are received. It is important that applications change the -values of these variables only when calling `readline()', not in a -signal handler, so Readline's internal signal state is not corrupted. - - - Variable: int rl_catch_signals - If this variable is non-zero, Readline will install signal - handlers for `SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', `SIGTSTP', - `SIGTTIN', and `SIGTTOU'. - - The default value of `rl_catch_signals' is 1. - - - Variable: int rl_catch_sigwinch - If this variable is non-zero, Readline will install a signal - handler for `SIGWINCH'. - - The default value of `rl_catch_sigwinch' is 1. - - If an application does not wish to have Readline catch any signals, -or to handle signals other than those Readline catches (`SIGHUP', for -example), Readline provides convenience functions to do the necessary -terminal and internal state cleanup upon receipt of a signal. - - - Function: void rl_cleanup_after_signal (void) - This function will reset the state of the terminal to what it was - before `readline()' was called, and remove the Readline signal - handlers for all signals, depending on the values of - `rl_catch_signals' and `rl_catch_sigwinch'. - - - Function: void rl_free_line_state (void) - This will free any partial state associated with the current input - line (undo information, any partial history entry, any - partially-entered keyboard macro, and any partially-entered - numeric argument).

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. - - -File: readline.info, Node: How Completing Works, Next: Completion Functions, Up: Custom Completers - -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: - - 1. The user-interface function `rl_complete()'. This function is - called with the same arguments as other bindable Readline - functions: COUNT and INVOKING_KEY. It isolates the word to be - completed and calls `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. - - 2. The internal function `rl_completion_matches()' uses an - application-supplied "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 - `rl_completion_entry_function'. - - 3. The generator function is called repeatedly from - `rl_completion_matches()', returning a string each time. The - arguments to the generator function are TEXT and STATE. TEXT is - the partial word to be completed. 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 `(char *)NULL' to - inform `rl_completion_matches()' that there are no more - possibilities left. Usually the generator function computes the - list of possible completions when 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 `malloc()'; - Readline frees the strings when it has finished with them. - - - - Function: 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 `rl_completion_matches()'). The default is to do filename - completion. - - - Variable: rl_compentry_func_t * rl_completion_entry_function - This is a pointer to the generator function for - `rl_completion_matches()'. If the value of - `rl_completion_entry_function' is `NULL' then the default filename - generator function, `rl_filename_completion_function()', is used. - - -File: readline.info, Node: Completion Functions, Next: Completion Variables, Prev: How Completing Works, Up: Custom Completers - -Completion Functions --------------------- - - Here is the complete list of callable completion functions present in -Readline. - - - Function: int rl_complete_internal (int what_to_do) - Complete the word at or before point. WHAT_TO_DO says what to do - with the completion. A value of `?' means list the possible - completions. `TAB' means do standard completion. `*' means - insert all of the possible completions. `!' means to display all - of the possible completions, if there is more than one, as well as - performing partial completion. - - - Function: 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 `rl_completion_matches()' and `rl_completion_entry_function'). - The default is to do filename completion. This calls - `rl_complete_internal()' with an argument depending on - INVOKING_KEY. - - - Function: int rl_possible_completions (int count, int invoking_key) - List the possible completions. See description of `rl_complete - ()'. This calls `rl_complete_internal()' with an argument of `?'. - - - Function: 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 `rl_complete()'. - This calls `rl_complete_internal()' with an argument of `*'. - - - Function: int rl_completion_mode (rl_command_func_t *cfunc) - Returns the apppriate value to pass to `rl_complete_internal()' - depending on whether CFUNC was called twice in succession and the - value of the `show-all-if-ambiguous' variable. - Application-specific completion functions may use this function to - present the same interface as `rl_complete()'. - - - Function: 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 - TEXT. If there are no completions, returns `NULL'. The first - entry in the returned array is the substitution for TEXT. The - remaining entries are the possible completions. The array is - terminated with a `NULL' pointer. - - ENTRY_FUNC is a function of two args, and returns a `char *'. The - first argument is TEXT. The second is a state argument; it is - zero on the first call, and non-zero on subsequent calls. - ENTRY_FUNC returns a `NULL' pointer to the caller when there are - no more matches. - - - Function: char * rl_filename_completion_function (const char *text, - int state) - A generator function for filename completion in the general case. - TEXT is a partial filename. The Bash source is a useful reference - for writing custom completion functions (the Bash completion - functions call this and other Readline functions). - - - Function: char * rl_username_completion_function (const char *text, - int state) - A completion generator for usernames. TEXT contains a partial - username preceded by a random character (usually `~'). As with all - completion generators, STATE is zero on the first call and non-zero - for subsequent calls. - - -File: readline.info, Node: Completion Variables, Next: A Short Completion Example, Prev: Completion Functions, Up: Custom Completers - -Completion Variables --------------------- - - - Variable: rl_compentry_func_t * rl_completion_entry_function - A pointer to the generator function for `rl_completion_matches()'. - `NULL' means to use `rl_filename_completion_function()', the - default filename completer. - - - Variable: rl_completion_func_t * rl_attempted_completion_function - A pointer to an alternative function to create matches. The - function is called with TEXT, START, and END. START and END are - indices in `rl_line_buffer' defining the boundaries of TEXT, which - is a character string. If this function exists and returns - `NULL', or if this variable is set to `NULL', then `rl_complete()' - will call the value of `rl_completion_entry_function' to generate - matches, otherwise the array of strings returned will be used. If - this function sets the `rl_attempted_completion_over' variable to - a non-zero value, Readline will not perform its default completion - even if this function returns no matches. - - - Variable: rl_quote_func_t * rl_filename_quoting_function - A pointer to a function that will quote a filename in an - application-specific fashion. This is called if filename - completion is being attempted and one of the characters in - `rl_filename_quote_characters' appears in a completed filename. - The function is called with TEXT, MATCH_TYPE, and QUOTE_POINTER. - The TEXT is the filename to be quoted. The MATCH_TYPE is either - `SINGLE_MATCH', if there is only one completion match, or - `MULT_MATCH'. Some functions use this to decide whether or not to - insert a closing quote character. The QUOTE_POINTER is a pointer - to any opening quote character the user typed. Some functions - choose to reset this character. - - - Variable: 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 TEXT, the text - of the word to be dequoted, and QUOTE_CHAR, which is the quoting - character that delimits the filename (usually `'' or `"'). If - QUOTE_CHAR is zero, the filename was not in an embedded string. - - - Variable: 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: TEXT, the text of the line, - and INDEX, the index of the character in the line. It is used to - decide whether a character found in - `rl_completer_word_break_characters' should be used to break words - for the completer. - - - Variable: 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 `NULL' terminated array of matches. - The first element (`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. - - - Variable: rl_icppfunc_t * rl_directory_completion_hook - This function, if defined, is allowed to modify the directory - portion of filenames Readline completes. 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 - displayed as part of the completion, replacing the directory - portion of the pathname the user typed. It returns an integer - that should be non-zero if the function modifies its directory - argument. It could be used to expand symbolic links or shell - variables in pathnames. - - - Variable: 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: (`char **'MATCHES, `int' - NUM_MATCHES, `int' MAX_LENGTH) where MATCHES is the array of - matching strings, NUM_MATCHES is the number of strings in that - array, and MAX_LENGTH is the length of the longest string in that - array. Readline provides a convenience function, - `rl_display_match_list', that takes care of doing the display to - Readline's output stream. That function may be called from this - hook. - - - Variable: const char * rl_basic_word_break_characters - The basic list of characters that signal a break between words for - the completer routine. The default value of this variable is the - characters which break words for completion in Bash: `" - \t\n\"\\'`@$><=;|&{("'. - - - Variable: const char * rl_basic_quote_characters - A list of quote characters which can cause a word break. - - - Variable: const char * rl_completer_word_break_characters - The list of characters that signal a break between words for - `rl_complete_internal()'. The default list is the value of - `rl_basic_word_break_characters'. - - - Variable: const char * rl_completer_quote_characters - A list of characters which can be used to quote a substring of the - line. Completion occurs on the entire substring, and within the - substring `rl_completer_word_break_characters' are treated as any - other character, unless they also appear within this list. - - - Variable: const char * rl_filename_quote_characters - A list of characters that cause a filename to be quoted by the - completer when they appear in a completed filename. The default - is the null string. - - - Variable: const char * rl_special_prefixes - The list of characters that are word break characters, but should - be left in TEXT when it is passed to the completion function. - Programs can use this to help determine what kind of completing to - do. For instance, Bash sets this variable to "$@" so that it can - complete shell variables and hostnames. - - - Variable: int rl_completion_query_items - Up to this many items will be displayed in response to a - possible-completions call. After that, we ask the user if she is - sure she wants to see them all. The default value is 100. - - - Variable: int rl_completion_append_character - When a single completion alternative matches at the end of the - command line, this character is appended to the inserted - completion text. The default is a space character (` '). Setting - this to the null character (`\0') prevents anything being appended - automatically. This can be changed in custom completion functions - to provide the "most sensible word separator character" according - to an application-specific command line syntax specification. - - - Variable: int rl_completion_suppress_append - If non-zero, RL_COMPLETION_APPEND_CHARACTER is not appended to - matches at the end of the command line, as described above. It is - set to 0 before any application-specific completion function is - called. - - - Variable: int rl_completion_mark_symlink_dirs - If non-zero, a slash will be appended to completed filenames that - are symbolic links to directory names, subject to the value of the - user-settable MARK-DIRECTORIES variable. This variable exists so - that application completion functions can override the user's - global preference (set via the MARK-SYMLINKED-DIRECTORIES Readline - variable) if appropriate. This variable is set to the user's - preference before any application completion function is called, - so unless that function modifies the value, the user's preferences - are honored. - - - Variable: int rl_ignore_completion_duplicates - If non-zero, then duplicates in the matches are removed.

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. - -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. Since some of the definitions -in @code{readline.h} use the @code{stdio} library, the file -@code{<stdio.h>} should be included before @code{readline.h}. - -@code{readline.h} defines a C preprocessor variable that should -be treated as an integer, @code{RL_READLINE_VERSION}, which may -be used to conditionally compile application code depending on -the installed Readline version. The value is a hexadecimal -encoding of the major and minor version numbers of the library, -of the form 0x@var{MMmm}. @var{MM} is the two-digit major -version number; @var{mm} is the two-digit minor version number. -For Readline 4.2, for example, the value of -@code{RL_READLINE_VERSION} would be @code{0x0402}. - -@menu -* Readline Typedefs:: C declarations to make code readable. -* Function Writing:: Variables and calling conventions. -@end menu - -@node Readline Typedefs -@subsection Readline Typedefs - -For readabilty, we declare a number of new object types, all pointers -to functions. - -The reason for declaring these new types is to make it easier to write -code describing pointers to C functions with appropriately prototyped -arguments and return values. - -For instance, say we want to declare a variable @var{func} as a pointer -to a function which takes two @code{int} arguments and returns an -@code{int} (this is the type of all of the Readline bindable functions). -Instead of the classic C declaration - -@code{int (*func)();} - -@noindent -or the ANSI-C style declaration - -@code{int (*func)(int, int);} - -@noindent -we may write - -@code{rl_command_func_t *func;} - -The full list of function pointer types available is - -@table @code -@item typedef int rl_command_func_t (int, int); - -@item typedef char *rl_compentry_func_t (const char *, int); - -@item typedef char **rl_completion_func_t (const char *, int, int); - -@item typedef char *rl_quote_func_t (char *, int, char *); - -@item typedef char *rl_dequote_func_t (char *, int); - -@item typedef int rl_compignore_func_t (char **); - -@item typedef void rl_compdisp_func_t (char **, int, int); - -@item typedef int rl_hook_func_t (void); - -@item typedef int rl_getc_func_t (FILE *); - -@item typedef int rl_linebuf_func_t (char *, int); - -@item typedef int rl_intfunc_t (int); -@item #define rl_ivoidfunc_t rl_hook_func_t -@item typedef int rl_icpfunc_t (char *); -@item typedef int rl_icppfunc_t (char **); - -@item typedef void rl_voidfunc_t (void); -@item typedef void rl_vintfunc_t (int); -@item typedef void rl_vcpfunc_t (char *); -@item typedef void rl_vcppfunc_t (char **); - -@end table - -@node Function Writing -@subsection Writing a New Function - -In order to write new functions for Readline, you need to know the -calling conventions for keyboard-invoked functions, and the names of the -variables that describe the current state of the line read so far. - -The calling sequence for a command @code{foo} looks like - -@example -@code{int foo (int count, int key)} -@end example - -@noindent -where @var{count} is the numeric argument (or 1 if defaulted) and -@var{key} is the key that invoked this function. - -It is completely up to the function as to what should be done with the -numeric argument. Some functions use it as a repeat count, some -as a flag, and others to choose alternate behavior (refreshing the current -line as opposed to refreshing the screen, for example). Some choose to -ignore it. In general, if a -function uses the numeric argument as a repeat count, it should be able -to do something useful with both negative and positive arguments. -At the very least, it should be aware that it can be passed a -negative argument. - -A command function should return 0 if its action completes successfully, -and a non-zero value if some error occurs. - -@node Readline Variables -@section Readline Variables - -These variables are available to function writers. - -@deftypevar {char *} rl_line_buffer -This is the line gathered so far.

This is done by representing the function with a descriptive -name. The user is able to type the descriptive name when referring to -the function. Thus, in an init file, one might find - -@example -Meta-Rubout: backward-kill-word -@end example - -This binds the keystroke @key{Meta-Rubout} to the function -@emph{descriptively} named @code{backward-kill-word}. You, as the -programmer, should bind the functions you write to descriptive names as -well. Readline provides a function for doing that: - -@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key) -Add @var{name} to the list of named functions. Make @var{function} be -the function that gets called. If @var{key} is not -1, then bind it to -@var{function} using @code{rl_bind_key()}. -@end deftypefun - -Using this function alone is sufficient for most applications. It is -the recommended way to add a few functions to the default functions that -Readline has built in. If you need to do something other -than adding a function to Readline, you may need to use the -underlying functions described below. - -@node Keymaps -@subsection Selecting a Keymap - -Key bindings take place on a @dfn{keymap}. The keymap is the -association between the keys that the user types and the functions that -get run.

They are intended to indicate -exceptional events, like a user pressing the interrupt key on his terminal, -or a network connection being broken. There is a class of signals that can -be sent to the process currently reading input from the keyboard. Since -Readline changes the terminal attributes when it is called, it needs to -perform special processing when such a signal is received in order to -restore the terminal to a sane state, or provide application writers with -functions to do so manually. - -Readline contains an internal signal handler that is installed for a -number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, -@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}). -When one of these signals is received, the signal handler -will reset the terminal attributes to those that were in effect before -@code{readline()} was called, reset the signal handling to what it was -before @code{readline()} was called, and resend the signal to the calling -application. -If and when the calling application's signal handler returns, Readline -will reinitialize the terminal and continue to accept input. -When a @code{SIGINT} is received, the Readline signal handler performs -some additional work, which will cause any partially-entered line to be -aborted (see the description of @code{rl_free_line_state()} below). - -There is an additional Readline signal handler, for @code{SIGWINCH}, which -the kernel sends to a process whenever the terminal's size changes (for -example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH} -handler updates Readline's internal screen size information, and then calls -any @code{SIGWINCH} signal handler the calling application has installed. -Readline calls the application's @code{SIGWINCH} signal handler without -resetting the terminal to its original state. If the application's signal -handler does more than update its idea of the terminal size and return (for -example, a @code{longjmp} back to a main processing loop), it @emph{must} -call @code{rl_cleanup_after_signal()} (described below), to restore the -terminal state. - -Readline provides two variables that allow application writers to -control whether or not it will catch certain signals and act on them -when they are received.

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. - -@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. -@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.

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.

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 -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 <RET>. You do not have to be at the end of -the line to press <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. - - -File: rluserman.info, Node: Readline Bare Essentials, Next: Readline Movement Commands, Up: Readline Interaction - -Readline Bare Essentials ------------------------- - - 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 `C-b' to move the cursor to the left, and then correct your -mistake. Afterwards, you can move the cursor to the right with `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. - -`C-b' - Move back one character. - -`C-f' - Move forward one character. - -<DEL> or <Backspace> - Delete the character to the left of the cursor. - -`C-d' - Delete the character underneath the cursor. - -Printing characters - Insert the character into the line at the cursor. - -`C-_' or `C-x C-u' - Undo the last editing command. You can undo all the way back to an - empty line. - -(Depending on your configuration, the <Backspace> key be set to delete -the character to the left of the cursor and the <DEL> key set to delete -the character underneath the cursor, like `C-d', rather than the -character to the left of the cursor.) - - -File: rluserman.info, Node: Readline Movement Commands, Next: Readline Killing Commands, Prev: Readline Bare Essentials, Up: Readline Interaction - -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 `C-b', `C-f', `C-d', and -<DEL>. Here are some commands for moving more rapidly about the line. - -`C-a' - Move to the start of the line. - -`C-e' - Move to the end of the line. - -`M-f' - Move forward a word, where a word is composed of letters and - digits. - -`M-b' - Move backward a word. - -`C-l' - Clear the screen, reprinting the current line at the top. - - Notice how `C-f' moves forward a character, while `M-f' moves -forward a word. It is a loose convention that control keystrokes -operate on characters while meta keystrokes operate on words. - - -File: rluserman.info, Node: Readline Killing Commands, Next: Readline Arguments, Prev: Readline Movement Commands, Up: Readline Interaction - -Readline Killing Commands -------------------------- - - "Killing" text means to delete the text from the line, but to save -it away for later use, usually by "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 "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. - - Here is the list of commands for killing text. - -`C-k' - Kill the text from the current cursor position to the end of the - line. - -`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 `M-f'. - -`M-<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 `M-b'. - -`C-w' - Kill from the cursor to the previous whitespace. This is - different than `M-<DEL>' because the word boundaries differ. - - Here is how to "yank" the text back into the line. Yanking means to -copy the most-recently-killed text from the kill buffer. - -`C-y' - Yank the most recently killed text back into the buffer at the - cursor. - -`M-y' - Rotate the kill-ring, and yank the new top. You can only do this - if the prior command is `C-y' or `M-y'. - - -File: rluserman.info, Node: Readline Arguments, Next: Searching, Prev: Readline Killing Commands, Up: Readline Interaction - -Readline Arguments ------------------- - - You can pass numeric arguments to Readline commands. Sometimes the -argument acts as a repeat count, other times it is the 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 `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 (`-'), 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 `C-d' command an argument of 10, you could type `M-1 0 C-d', which -will delete the next ten characters on the input line. - - -File: rluserman.info, Node: Searching, Prev: Readline Arguments, Up: Readline Interaction - -Searching for Commands in the History -------------------------------------- - - Readline provides commands for searching through the command history -for lines containing a specified string. There are two search modes: -"incremental" and "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 `C-r'. Typing `C-s' searches -forward through the history. The characters present in the value of -the `isearch-terminators' variable are used to terminate an incremental -search. If that variable has not been assigned a value, the <ESC> and -`C-J' characters will terminate an incremental search. `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 `C-r' or -`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 <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 -`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. - - -File: rluserman.info, Node: Readline Init File, Next: Bindable Readline Commands, Prev: Readline Interaction, Up: Command Line Editing - -Readline Init File -================== - - 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 "inputrc" file, conventionally in his home -directory. The name of this file is taken from the value of the -environment variable `INPUTRC'. If that variable is unset, the default -is `~/.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 `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. - - -File: rluserman.info, Node: Readline Init File Syntax, Next: Conditional Init Constructs, Up: Readline Init File - -Readline Init File Syntax -------------------------- - - There are only a few basic constructs allowed in the Readline init -file. Blank lines are ignored. Lines beginning with a `#' are -comments. Lines beginning with a `$' indicate conditional constructs -(*note Conditional Init Constructs::). Other lines denote variable -settings and key bindings. - -Variable Settings - You can modify the run-time behavior of Readline by altering the - values of variables in Readline using the `set' command within the - init file. The syntax is simple: - - set VARIABLE VALUE - - Here, for example, is how to change from the default Emacs-like - key binding to use `vi' line editing commands: - - set editing-mode vi - - Variable names and values, where appropriate, are recognized - without regard to case. - - A great deal of run-time behavior is changeable with the following - variables. - - `bell-style' - Controls what happens when Readline wants to ring the - terminal bell. If set to `none', Readline never rings the - bell. If set to `visible', Readline uses a visible bell if - one is available. If set to `audible' (the default), - Readline attempts to ring the terminal's bell. - - `comment-begin' - The string to insert at the beginning of the line when the - `insert-comment' command is executed. The default value is - `"#"'. - - `completion-ignore-case' - If set to `on', Readline performs filename matching and - completion in a case-insensitive fashion. The default value - is `off'. - - `completion-query-items' - The number of possible completions that determines when the - user is asked whether he wants to see the list of - possibilities. 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. The default limit is `100'. - - `convert-meta' - If set to `on', Readline will convert characters with the - eighth bit set to an ASCII key sequence by stripping the - eighth bit and prefixing an <ESC> character, converting them - to a meta-prefixed key sequence. The default value is `on'. - - `disable-completion' - If set to `On', Readline will inhibit word completion. - Completion characters will be inserted into the line as if - they had been mapped to `self-insert'. The default is `off'. - - `editing-mode' - The `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 `emacs' or `vi'. - - `enable-keypad' - When set to `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 `off'. - - `expand-tilde' - If set to `on', tilde expansion is performed when Readline - attempts word completion. The default is `off'. - - If set to `on', the history code attempts to place point at - the same location on each history line retrived with - `previous-history' or `next-history'. - - `horizontal-scroll-mode' - This variable can be set to either `on' or `off'. Setting it - to `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 `off'. - - `input-meta' - If set to `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 `off'. The name `meta-flag' is a synonym - for this variable. - - `isearch-terminators' - The string of characters that should terminate an incremental - search without subsequently executing the character as a - command (*note Searching::). If this variable has not been - given a value, the characters <ESC> and `C-J' will terminate - an incremental search. - - `keymap' - Sets Readline's idea of the current keymap for key binding - commands. Acceptable `keymap' names are `emacs', - `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move', - `vi-command', and `vi-insert'. `vi' is equivalent to - `vi-command'; `emacs' is equivalent to `emacs-standard'. The - default value is `emacs'. The value of the `editing-mode' - variable also affects the default keymap. - - `mark-directories' - If set to `on', completed directory names have a slash - appended. The default is `on'. - - `mark-modified-lines' - This variable, when set to `on', causes Readline to display an - asterisk (`*') at the start of history lines which have been - modified. This variable is `off' by default. - - `mark-symlinked-directories' - If set to `on', completed names which are symbolic links to - directories have a slash appended (subject to the value of - `mark-directories'). The default is `off'. - - `match-hidden-files' - This variable, when set to `on', causes Readline to match - files whose names begin with a `.' (hidden files) when - performing filename completion, unless the leading `.' is - supplied by the user in the filename to be completed. This - variable is `on' by default. - - `output-meta' - If set to `on', Readline will display characters with the - eighth bit set directly rather than as a meta-prefixed escape - sequence. The default is `off'. - - `page-completions' - If set to `on', Readline uses an internal `more'-like pager - to display a screenful of possible completions at a time. - This variable is `on' by default. - - `print-completions-horizontally' - If set to `on', Readline will display completions with matches - sorted horizontally in alphabetical order, rather than down - the screen. The default is `off'. - - `show-all-if-ambiguous' - This alters the default behavior of the completion functions. - If set to `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 `off'. - - `visible-stats' - If set to `on', a character denoting a file's type is - appended to the filename when listing possible completions. - The default is `off'. - -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. 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 MACRO). - - KEYNAME: FUNCTION-NAME or MACRO - KEYNAME is the name of a key spelled out in English. For - example: - Control-u: universal-argument - Meta-Rubout: backward-kill-word - Control-o: "> output" - - In the above example, `C-u' is bound to the function - `universal-argument', `M-DEL' is bound to the function - `backward-kill-word', and `C-o' is bound to run the macro - expressed on the right hand side (that is, to insert the text - `> output' into the line). - - A number of symbolic character names are recognized while - processing this key binding syntax: DEL, ESC, ESCAPE, LFD, - NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB. - - "KEYSEQ": FUNCTION-NAME or MACRO - KEYSEQ differs from KEYNAME above in that strings denoting an - entire key sequence can be specified, by placing the key - sequence in double quotes. Some GNU Emacs style key escapes - can be used, as in the following example, but the special - character names are not recognized. - - "\C-u": universal-argument - "\C-x\C-r": re-read-init-file - "\e[11~": "Function Key 1" - - In the above example, `C-u' is again bound to the function - `universal-argument' (just as it was in the first example), - `C-x C-r' is bound to the function `re-read-init-file', and - `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function - Key 1'. - - The following GNU Emacs style escape sequences are available when - specifying key sequences: - - `\C-' - control prefix - - `\M-' - meta prefix - - `\e' - an escape character - - `\\' - backslash - - `\"' - <">, a double quotation mark - - `\'' - <'>, a single quote or apostrophe - - In addition to the GNU Emacs style escape sequences, a second set - of backslash escapes is available: - - `\a' - alert (bell) - - `\b' - backspace - - `\d' - delete - - `\f' - form feed - - `\n' - newline - - `\r' - carriage return - - `\t' - horizontal tab - - `\v' - vertical tab - - `\NNN' - the eight-bit character whose value is the octal value NNN - (one to three digits) - - `\xHH' - the eight-bit character whose value is the hexadecimal value - HH (one or two hex digits) - - When entering the text of a macro, single or double quotes must 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 `''. For example, - the following binding will make `C-x \' insert a single `\' into - the line: - "\C-x\\": "\\" - - -File: rluserman.info, Node: Conditional Init Constructs, Next: Sample Init File, Prev: Readline Init File Syntax, Up: Readline Init File - -Conditional Init Constructs ---------------------------- - - 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. - -`$if' - The `$if' construct allows bindings to be made based on the - editing mode, the terminal being used, or the application using - Readline. The text of the test extends to the end of the line; no - characters are required to isolate it. - - `mode' - The `mode=' form of the `$if' directive is used to test - whether Readline is in `emacs' or `vi' mode. This may be - used in conjunction with the `set keymap' command, for - instance, to set bindings in the `emacs-standard' and - `emacs-ctlx' keymaps only if Readline is starting out in - `emacs' mode. - - `term' - The `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 - `=' is tested against both the full name of the terminal and - the portion of the terminal name before the first `-'. This - allows `sun' to match both `sun' and `sun-cmd', for instance. - - `application' - The APPLICATION construct is used to include - application-specific settings. Each program using the - Readline library sets the 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: - $if Bash - # Quote the current or previous word - "\C-xq": "\eb\"\ef\"" - $endif - -`$endif' - This command, as seen in the previous example, terminates an `$if' - command. - -`$else' - Commands in this branch of the `$if' directive are executed if the - test fails. - -`$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 `/etc/inputrc': - $include /etc/inputrc - - -File: rluserman.info, Node: Sample Init File, Prev: Conditional Init Constructs, Up: Readline Init File - -Sample Init File ----------------- - - Here is an example of an INPUTRC file.

This is an incremental search. - -`forward-search-history (C-s)' - Search forward starting at the current line and moving `down' - through the the history as necessary. This is an incremental - search. - -`non-incremental-reverse-search-history (M-p)' - Search backward starting at the current line and moving `up' - through the history as necessary using a non-incremental search - for a string supplied by the user. - -`non-incremental-forward-search-history (M-n)' - Search forward starting at the current line and moving `down' - through the the history as necessary using a non-incremental search - for a string supplied by the user. - -`history-search-forward ()' - Search forward through the history for the string of characters - between the start of the current line and the point. This is a - non-incremental search. By default, this command is unbound. - -`history-search-backward ()' - Search backward through the history for the string of characters - between the start of the current line and the point. This is a - non-incremental search. By default, this command is unbound. - -`yank-nth-arg (M-C-y)' - Insert the first argument to the previous command (usually the - second word on the previous line) at point. With an argument N, - insert the Nth word from the previous command (the words in the - previous command begin with word 0). A negative argument inserts - the Nth word from the end of the previous command. - -`yank-last-arg (M-. or M-_)' - Insert last argument to the previous command (the last word of the - previous history entry). With an argument, behave exactly like - `yank-nth-arg'. Successive calls to `yank-last-arg' move back - through the history list, inserting the last argument of each line - in turn. - - -File: rluserman.info, Node: Commands For Text, Next: Commands For Killing, Prev: Commands For History, Up: Bindable Readline Commands - -Commands For Changing Text --------------------------- - -`delete-char (C-d)' - Delete the character at point. If point is at the beginning of - the line, there are no characters in the line, and the last - character typed was not bound to `delete-char', then return EOF. - -`backward-delete-char (Rubout)' - Delete the character behind the cursor. A numeric argument means - to kill the characters instead of deleting them. - -`forward-backward-delete-char ()' - Delete the character under the cursor, unless the cursor is at the - end of the line, in which case the character behind the cursor is - deleted. By default, this is not bound to a key. - -`quoted-insert (C-q or C-v)' - Add the next character typed to the line verbatim. This is how to - insert key sequences like `C-q', for example. - -`tab-insert (M-<TAB>)' - Insert a tab character. - -`self-insert (a, b, A, 1, !, ...)' - Insert yourself. - -`transpose-chars (C-t)' - Drag the character before the cursor forward over the character at - the cursor, moving the cursor forward as well. If the insertion - point is at the end of the line, then this transposes the last two - characters of the line. Negative arguments have no effect. - -`transpose-words (M-t)' - Drag the word before point past the word after point, moving point - past that word as well. If the insertion point is at the end of - the line, this transposes the last two words on the line. - -`upcase-word (M-u)' - Uppercase the current (or following) word. With a negative - argument, uppercase the previous word, but do not move the cursor. - -`downcase-word (M-l)' - Lowercase the current (or following) word. With a negative - argument, lowercase the previous word, but do not move the cursor. - -`capitalize-word (M-c)' - Capitalize the current (or following) word. With a negative - argument, capitalize the previous word, but do not move the cursor. - -`overwrite-mode ()' - Toggle overwrite mode. With an explicit positive numeric argument, - switches to overwrite mode. With an explicit non-positive numeric - argument, switches to insert mode. This command affects only - `emacs' mode; `vi' mode does overwrite differently. Each call to - `readline()' starts in insert mode. - - In overwrite mode, characters bound to `self-insert' replace the - text at point rather than pushing the text to the right. - Characters bound to `backward-delete-char' replace the character - before point with a space. - - By default, this command is unbound. - - -File: rluserman.info, Node: Commands For Killing, Next: Numeric Arguments, Prev: Commands For Text, Up: Bindable Readline Commands - -Killing And Yanking -------------------- - -`kill-line (C-k)' - Kill the text from point to the end of the line. - -`backward-kill-line (C-x Rubout)' - Kill backward to the beginning of the line. - -`unix-line-discard (C-u)' - Kill backward from the cursor to the beginning of the current line. - -`kill-whole-line ()' - Kill all characters on the current line, no matter where point is. - By default, this is unbound. - -`kill-word (M-d)' - Kill from point to the end of the current word, or if between - words, to the end of the next word. Word boundaries are the same - as `forward-word'. - -`backward-kill-word (M-<DEL>)' - Kill the word behind point. Word boundaries are the same as - `backward-word'. - -`unix-word-rubout (C-w)' - Kill the word behind point, using white space as a word boundary. - The killed text is saved on the kill-ring. - -`delete-horizontal-space ()' - Delete all spaces and tabs around point. By default, this is - unbound. - -`kill-region ()' - Kill the text in the current region. By default, this command is - unbound. - -`copy-region-as-kill ()' - Copy the text in the region to the kill buffer, so it can be yanked - right away. By default, this command is unbound. - -`copy-backward-word ()' - Copy the word before point to the kill buffer. The word - boundaries are the same as `backward-word'. By default, this - command is unbound. - -`copy-forward-word ()' - Copy the word following point to the kill buffer. The word - boundaries are the same as `forward-word'. By default, this - command is unbound. - -`yank (C-y)' - Yank the top of the kill ring into the buffer at point. - -`yank-pop (M-y)' - Rotate the kill-ring, and yank the new top. You can only do this - if the prior command is `yank' or `yank-pop'. - - -File: rluserman.info, Node: Numeric Arguments, Next: Commands For Completion, Prev: Commands For Killing, Up: Bindable Readline Commands - -Specifying Numeric Arguments ----------------------------- - -`digit-argument (M-0, M-1, ... M--)' - Add this digit to the argument already accumulating, or start a new - argument. `M--' starts a negative argument. - -`universal-argument ()' - This is another way to specify an argument. If this command is - followed by one or more digits, optionally with a leading minus - sign, those digits define the argument. If the command is - followed by digits, executing `universal-argument' again ends the - numeric argument, but is otherwise ignored. As a special case, if - this command is immediately followed by a character that is - neither a digit or minus sign, the argument count for the next - command is multiplied by four. The argument count is initially - one, so executing this function the first time makes the argument - count four, a second time makes the argument count sixteen, and so - on. By default, this is not bound to a key. - - -File: rluserman.info, Node: Commands For Completion, Next: Keyboard Macros, Prev: Numeric Arguments, Up: Bindable Readline Commands - -Letting Readline Type For You ------------------------------ - -`complete (<TAB>)' - Attempt to perform completion on the text before point. The - actual completion performed is application-specific. The default - is filename completion. - -`possible-completions (M-?)' - List the possible completions of the text before point. - -`insert-completions (M-*)' - Insert all completions of the text before point that would have - been generated by `possible-completions'. - -`menu-complete ()' - Similar to `complete', but replaces the word to be completed with - a single match from the list of possible completions. Repeated - execution of `menu-complete' steps through the list of possible - completions, inserting each match in turn. At the end of the list - of completions, the bell is rung (subject to the setting of - `bell-style') and the original text is restored. An argument of N - moves N positions forward in the list of matches; a negative - argument may be used to move backward through the list. This - command is intended to be bound to <TAB>, but is unbound by - default. - -`delete-char-or-list ()' - Deletes the character under the cursor if not at the beginning or - end of the line (like `delete-char'). If at the end of the line, - behaves identically to `possible-completions'. This command is - unbound by default. - - -File: rluserman.info, Node: Keyboard Macros, Next: Miscellaneous Commands, Prev: Commands For Completion, Up: Bindable Readline Commands - -Keyboard Macros ---------------- - -`start-kbd-macro (C-x ()' - Begin saving the characters typed into the current keyboard macro. - -`end-kbd-macro (C-x ))' - Stop saving the characters typed into the current keyboard macro - and save the definition. - -`call-last-kbd-macro (C-x e)' - Re-execute the last keyboard macro defined, by making the - characters in the macro appear as if typed at the keyboard. - - -File: rluserman.info, Node: Miscellaneous Commands, Prev: Keyboard Macros, Up: Bindable Readline Commands - -Some Miscellaneous Commands ---------------------------- - -`re-read-init-file (C-x C-r)' - Read in the contents of the INPUTRC file, and incorporate any - bindings or variable assignments found there. - -`abort (C-g)' - Abort the current editing command and ring the terminal's bell - (subject to the setting of `bell-style'). - -`do-uppercase-version (M-a, M-b, M-X, ...)' - If the metafied character X is lowercase, run the command that is - bound to the corresponding uppercase character. - -`prefix-meta (<ESC>)' - Metafy the next character typed. This is for keyboards without a - meta key. Typing `<ESC> f' is equivalent to typing `M-f'. - -`undo (C-_ or C-x C-u)' - Incremental undo, separately remembered for each line. - -`revert-line (M-r)' - Undo all changes made to this line. This is like executing the - `undo' command enough times to get back to the beginning. - -`tilde-expand (M-~)' - Perform tilde expansion on the current word. - -`set-mark (C-@)' - Set the mark to the point. If a numeric argument is supplied, the - mark is set to that position. - -`exchange-point-and-mark (C-x C-x)' - Swap the point with the mark. The current cursor position is set - to the saved position, and the old cursor position is saved as the - mark. - -`character-search (C-])' - A character is read and point is moved to the next occurrence of - that character. A negative count searches for previous - occurrences. - -`character-search-backward (M-C-])' - A character is read and point is moved to the previous occurrence - of that character. A negative count searches for subsequent - occurrences. - -`insert-comment (M-#)' - Without a numeric argument, the value of the `comment-begin' - variable is inserted at the beginning of the current line. If a - numeric argument is supplied, this command acts as a toggle: if - the characters at the beginning of the line do not match the value - of `comment-begin', the value is inserted, otherwise the - characters in `comment-begin' are deleted from the beginning of - the line. In either case, the line is accepted as if a newline - had been typed. - -`dump-functions ()' - Print all of the functions and their key bindings to the Readline - output stream. If a numeric argument is supplied, the output is - formatted in such a way that it can be made part of an INPUTRC - file. This command is unbound by default. - -`dump-variables ()' - Print all of the settable variables and their values to the - Readline output stream. If a numeric argument is supplied, the - output is formatted in such a way that it can be made part of an - INPUTRC file. This command is unbound by default. - -`dump-macros ()' - Print all of the Readline key sequences bound to macros and the - strings they output. If a numeric argument is supplied, the - output is formatted in such a way that it can be made part of an - INPUTRC file. This command is unbound by default. - -`emacs-editing-mode (C-e)' - When in `vi' command mode, this causes a switch to `emacs' editing - mode. - -`vi-editing-mode (M-C-j)' - When in `emacs' editing mode, this causes a switch to `vi' editing - mode. - - -File: rluserman.info, Node: Readline vi Mode, Prev: Bindable Readline Commands, Up: Command Line Editing - -Readline vi Mode -================ - - While the Readline library does not have a full set of `vi' editing -functions, it does contain enough to allow simple editing of the line. -The Readline `vi' mode behaves as specified in the POSIX 1003.2 -standard. - - In order to switch interactively between `emacs' and `vi' editing -modes, use the command `M-C-j' (bound to emacs-editing-mode when in -`vi' mode and to vi-editing-mode in `emacs' mode). The Readline -default is `emacs' mode. - - When you enter a line in `vi' mode, you are already placed in -`insertion' mode, as if you had typed an `i'. Pressing <ESC> switches -you into `command' mode, where you can edit the text of the line with -the standard `vi' movement keys, move to previous history lines with -`k' and subsequent lines with `j',

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?
