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/COPYING b/readline-4.3/COPYING new file mode 100644 index 0000000..1bf1526 --- /dev/null +++ b/readline-4.3/COPYING @@ -0,0 +1,339 @@ + 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. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. 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.

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/MANIFEST b/readline-4.3/MANIFEST new file mode 100644 index 0000000..1507eda --- /dev/null +++ b/readline-4.3/MANIFEST @@ -0,0 +1,126 @@ +# +# 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/Makefile.in b/readline-4.3/Makefile.in new file mode 100644 index 0000000..0ff0c31 --- /dev/null +++ b/readline-4.3/Makefile.in @@ -0,0 +1,520 @@ +## -*- 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.

+++ b/readline-4.3/README @@ -0,0 +1,172 @@ +Introduction +============ + +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/USAGE b/readline-4.3/USAGE new file mode 100644 index 0000000..edc9f54 --- /dev/null +++ b/readline-4.3/USAGE @@ -0,0 +1,37 @@ +From rms@gnu.org Thu Jul 22 20:37:55 1999 +Flags: 10 +Return-Path: rms@gnu.org +Received: from arthur.INS.CWRU.Edu (root@arthur.INS.CWRU.Edu [129.22.8.215]) by odin.INS.CWRU.Edu with ESMTP (8.8.6+cwru/CWRU-2.4-ins) + id UAA25349; Thu, 22 Jul 1999 20:37:54 -0400 (EDT) (from rms@gnu.org for <chet@odin.INS.CWRU.Edu>) +Received: from nike.ins.cwru.edu (root@nike.INS.CWRU.Edu [129.22.8.219]) by arthur.INS.CWRU.Edu with ESMTP (8.8.8+cwru/CWRU-3.6) + id UAA05311; Thu, 22 Jul 1999 20:37:51 -0400 (EDT) (from rms@gnu.org for <chet@po.cwru.edu>) +Received: from pele.santafe.edu (pele.santafe.edu [192.12.12.119]) by nike.ins.cwru.edu with ESMTP (8.8.7/CWRU-2.5-bsdi) + id UAA13350; Thu, 22 Jul 1999 20:37:50 -0400 (EDT) (from rms@gnu.org for <chet@nike.ins.cwru.edu>) +Received: from wijiji.santafe.edu (wijiji [192.12.12.5]) + by pele.santafe.edu (8.9.1/8.9.1) with ESMTP id SAA10831 + for <chet@nike.ins.cwru.edu>; Thu, 22 Jul 1999 18:37:47 -0600 (MDT) +Received: (from rms@localhost) + by wijiji.santafe.edu (8.9.1b+Sun/8.9.1) id SAA01089; + Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Date: Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Message-Id: <199907230037.SAA01089@wijiji.santafe.edu> +X-Authentication-Warning: wijiji.santafe.edu: rms set sender to rms@gnu.org using -f +From: Richard Stallman <rms@gnu.org> +To: chet@nike.ins.cwru.edu +Subject: Use of Readline +Reply-to: rms@gnu.org + +I think Allbery's suggestion is a good one.

The 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.

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 +initializes the interactive variables. + +.Fn1 "HISTORY_STATE *" history_get_history_state void +Return a structure describing the current state of the input history. + +.Fn1 void history_set_history_state "HISTORY_STATE *state" +Set the state of the history list according to \fIstate\fP. + +.SS History List Management + +These functions manage individual entries on the history list, or set +parameters managing the list itself. + +.Fn1 void add_history "const char *string" +Place \fIstring\fP at the end of the history list. The associated data +field (if any) is set to \fBNULL\fP. + +.Fn1 "HIST_ENTRY *" remove_history "int which" +Remove history entry at offset \fIwhich\fP from the history. The +removed element is returned so you can free the line, data, +and containing structure. + +.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data" +Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP. +This returns the old entry so you can dispose of the data. In the case +of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned. + +.Fn1 void clear_history "void" +Clear the history list by deleting all the entries. + +.Fn1 void stifle_history "int max" +Stifle the history list, remembering only the last \fImax\fP entries. + +.Fn1 int unstifle_history "void" +Stop stifling the history. 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. Element 0 of this list is the beginning of time. +If there is no history, return \fBNULL\fP. + +.Fn1 int where_history "void" +Returns the offset of the current history element. + +.Fn1 "HIST_ENTRY *" current_history "void" +Return the history entry at the current position, as determined by +\fBwhere_history()\fP. If there is no entry there, return a \fBNULL\fP +pointer. + +.Fn1 "HIST_ENTRY *" history_get "int offset" +Return the history entry at position \fIoffset\fP, starting from +\fBhistory_base\fP. +If there is no entry there, or if \fIoffset\fP +is greater than the history length, return a \fBNULL\fP pointer. + +.Fn1 int history_total_bytes "void" +Return the number of bytes that the primary history entries are using. +This function returns the sum of the lengths of all the lines in the +history. + +.SS Moving Around the History List + +These functions allow the current index into the history list to be +set or changed. + +.Fn1 int history_set_pos "int pos" +Set the current history offset to \fIpos\fP, an absolute index +into the list. +Returns 1 on success, 0 if \fIpos\fP is less than zero or greater +than the number of history entries. + +.Fn1 "HIST_ENTRY *" previous_history "void" +Back up the current history offset to the previous history entry, and +return a pointer to that entry. 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. 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 entry, and the return value is 0. +Otherwise, nothing is changed, and a -1 is returned. + +.Fn3 int history_search_pos "const char *string" "int direction" "int pos" +Search for \fIstring\fP in the history list, starting at \fIpos\fP, an +absolute index into the list. If \fIdirection\fP is negative, the search +proceeds backward from \fIpos\fP, otherwise forward. 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. Returns: +.RS +.PD 0 +.TP +0 +If no expansions took place (or, if the only change in +the text was the removal of escape characters preceding the history expansion +character); +.TP +1 +if expansions did take place; +.TP +-1 +if there was an error in expansion; +.TP +2 +if the returned line should be displayed, but not executed, +as with the \fB:p\fP modifier. +.PD +.RE +If an error ocurred in expansion, then \fIoutput\fP contains a descriptive +error message. + +.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar" +Returns the text of the history event beginning at \fIstring\fP + +\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event +specifier. At function entry, \fIcindex\fP points to the index into +\fIstring\fP where the history event specification begins. \fIqchar\fP +is a character that is allowed to end the event specification in addition +to the ``normal'' terminating characters. + +.Fn1 "char **" history_tokenize "const char *string" +Return an array of tokens parsed out of \fIstring\fP, much as the +shell might. +The tokens are split on the characters in the +\fBhistory_word_delimiters\fP variable, +and shell quoting conventions are obeyed. + +.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string" +Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP +arguments present in \fIstring\fP. Arguments are split using +\fBhistory_tokenize()\fP. + +.SS History Variables + +This section describes the externally-visible variables exported by +the GNU History Library. + +.Vb int history_base +The logical offset of the first entry in the history list. + +.Vb int history_length +The number of entries currently stored in the history list. + +.Vb int history_max_entries +The maximum number of history entries. This must be changed using +\fBstifle_history()\fP. + +.Vb char history_expansion_char +The character that introduces a history event. The default is \fB!\fP. +Setting this to 0 inhibits history expansion. + +.Vb char history_subst_char +The character that invokes word substitution if found at the start of +a line.

After saving the history, the history file is truncated +to contain no more than @env{$HISTFILESIZE} +lines. If @env{HISTFILESIZE} is not set, no truncation is performed. + +The builtin command @code{fc} may be used to list or edit and re-execute +a portion of the history list. +The @code{history} builtin may be used to display or modify the history +list and manipulate the history file. +When using command-line editing, search commands +are available in each editing mode that provide access to the +history list (@pxref{Commands For History}). + +The shell allows control over which commands are saved on the history +list. The @env{HISTCONTROL} and @env{HISTIGNORE} +variables may be set to cause the shell to save only a subset of the +commands entered. +The @code{cmdhist} +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The @code{lithist} +shell option causes the shell to save the command with embedded newlines +instead of semicolons. +The @code{shopt} builtin is used to set these options. +@xref{Bash Builtins}, for a description of @code{shopt}. + +@node Bash History Builtins +@section Bash History Builtins +@cindex history builtins + +Bash provides two builtin commands which manipulate the +history list and history file. + +@table @code + +@item fc +@btindex fc +@example +@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]} +@code{fc -s [@var{pat}=@var{rep}] [@var{command}]} +@end example + +Fix Command. In the first form, a range of commands from @var{first} to +@var{last} is selected from the history list. Both @var{first} and +@var{last} may be specified as a string (to locate the most recent +command beginning with that string) or as a number (an index into the +history list, where a negative number is used as an offset from the +current command number). If @var{last} is not specified it is set to +@var{first}. If @var{first} is not specified it is set to the previous +command for editing and @minus{}16 for listing. If the @option{-l} flag is +given, the commands are listed on standard output. The @option{-n} flag +suppresses the command numbers when listing. The @option{-r} flag +reverses the order of the listing. Otherwise, the editor given by +@var{ename} is invoked on a file containing those commands. If +@var{ename} is not given, the value of the following variable expansion +is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}. This says to use the +value of the @env{FCEDIT} variable if set, or the value of the +@env{EDITOR} variable if that is set, or @code{vi} if neither is set. +When editing is complete, the edited commands are echoed and executed. + +In the second form, @var{command} is re-executed after each instance +of @var{pat} in the selected command is replaced by @var{rep}. + +A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so +that typing @samp{r cc} runs the last command beginning with @code{cc} +and typing @samp{r} re-executes the last command (@pxref{Aliases}). + +@item history +@btindex history +@example +history [@var{n}] +history -c +history -d @var{offset} +history [-anrw] [@var{filename}] +history -ps @var{arg} +@end example + +With no options, display the history list with line numbers. +Lines prefixed with a @samp{*} have been modified. +An argument of @var{n} lists only the last @var{n} lines. +Options, if supplied, have the following meanings: + +@table @code +@item -c +Clear the history list.

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 +@dfn{event}, and the portions of that line that are acted upon are +called @dfn{words}. Various @dfn{modifiers} are available to manipulate +the selected words. The line is broken into words in the same fashion +that Bash does, so that several words +surrounded by quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is @samp{!} by default. +@ifset BashFeatures +Only @samp{\} and @samp{'} may be used to escape the history expansion +character. +@end ifset + +@ifset BashFeatures +Several shell options settable with the @code{shopt} +builtin (@pxref{Bash Builtins}) may be used to tailor +the behavior of history expansion. If the +@code{histverify} shell option is enabled, and Readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the Readline +editing buffer for further modification. +If Readline is being used, and the @code{histreedit} +shell option is enabled, a failed history expansion will be +reloaded into the Readline editing buffer for correction. +The @option{-p} option to the @code{history} builtin command +may be used to see what a history expansion will do before using it. +The @option{-s} option to the @code{history} builtin may be used to +add commands to the end of the history list without actually executing +them, so that they are available for subsequent recall. +This is most useful in conjunction with Readline. + +The shell allows control of the various characters used by the +history expansion mechanism with the @code{histchars} variable. +@end ifset + +@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. +@end menu + +@node Event Designators +@subsection Event Designators +@cindex event designators + +An event designator is a reference to a command line entry in the +history list. +@cindex history events + +@table @asis + +@item @code{!} +Start a history substitution, except when followed by a space, tab, +the end of the line, @samp{=} or @samp{(}. + +@item @code{!@var{n}} +Refer to command line @var{n}. + +@item @code{!-@var{n}} +Refer to the command @var{n} lines back. + +@item @code{!!} +Refer to the previous command.

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.

interface between the @sc{gnu} Readline Library and +other programs. If you are a programmer, and you wish to include the +features found in @sc{gnu} Readline +such as completion, line editing, and interactive history manipulation +in your own programs, this section is for you. + +@menu +* Basic Behavior:: Using the default behavior of Readline. +* Custom Functions:: Adding your own functions to Readline. +* Readline Variables:: Variables accessible to custom + functions. +* Readline Convenience Functions:: Functions which Readline supplies to + aid in writing your own custom + functions. +* Readline Signal Handling:: How Readline behaves when it receives signals. +* Custom Completers:: Supplanting or supplementing Readline's + completion functions. +@end menu + +@node Basic Behavior +@section Basic Behavior + +Many programs provide a command line interface, such as @code{mail}, +@code{ftp}, and @code{sh}. 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.

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

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

Specifically, +@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all +stand for themselves when seen in this text, or in an init file +(@pxref{Readline Init File}). +If your keyboard lacks a @key{LFD} key, typing @key{C-j} will +produce the desired character. +The @key{RET} key may be labeled @key{Return} or @key{Enter} on +some keyboards. + +@node Readline Interaction +@section Readline Interaction +@cindex interaction, readline + +Often during an interactive session you type in a long line of text, +only to notice that the first word on the line is misspelled. The +Readline library gives you a set of commands for manipulating the text +as you type it in, allowing you to just fix your typo, and not forcing +you to retype the majority of the line. Using these editing commands, +you move the cursor to the place that needs correction, and delete or +insert the text of the corrections. Then, when you are satisfied with +the line, you simply press @key{RET}. You do not have to be at the +end of the line to press @key{RET}; the entire line is accepted +regardless of the location of the cursor within the line. + +@menu +* Readline Bare Essentials:: The least you need to know about Readline. +* Readline Movement Commands:: Moving about the input line. +* Readline Killing Commands:: How to delete text, and how to get it back! +* Readline Arguments:: Giving numeric arguments to commands. +* Searching:: Searching through previous lines. +@end menu + +@node Readline Bare Essentials +@subsection Readline Bare Essentials +@cindex notation, readline +@cindex command editing +@cindex editing command lines + +In order to enter characters into the line, simply type them. The typed +character appears where the cursor was, and then the cursor moves one +space to the right. If you mistype a character, you can use your +erase character to back up and delete the mistyped character. + +Sometimes you may mistype a character, and +not notice the error until you have typed several other characters. In +that case, you can type @kbd{C-b} to move the cursor to the left, and then +correct your mistake. Afterwards, you can move the cursor to the right +with @kbd{C-f}. + +When you add text in the middle of a line, you will notice that characters +to the right of the cursor are `pushed over' to make room for the text +that you have inserted. Likewise, when you delete text behind the cursor, +characters to the right of the cursor are `pulled back' to fill in the +blank space created by the removal of the text. A list of the bare +essentials for editing the text of an input line follows. + +@table @asis +@item @kbd{C-b} +Move back one character. +@item @kbd{C-f} +Move forward one character. +@item @key{DEL} or @key{Backspace} +Delete the character to the left of the cursor. +@item @kbd{C-d} +Delete the character underneath the cursor. +@item @w{Printing characters} +Insert the character into the line at the cursor. +@item @kbd{C-_} or @kbd{C-x C-u} +Undo the last editing command. You can undo all the way back to an +empty line. +@end table + +@noindent +(Depending on your configuration, the @key{Backspace} key be set to +delete the character to the left of the cursor and the @key{DEL} key set +to delete the character underneath the cursor, like @kbd{C-d}, rather +than the character to the left of the cursor.) + +@node Readline Movement Commands +@subsection Readline Movement Commands + + +The above table describes the most basic keystrokes that you need +in order to do editing of the input line. For your convenience, many +other commands have been added in addition to @kbd{C-b}, @kbd{C-f}, +@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly +about the line. + +@table @kbd +@item C-a +Move to the start of the line. +@item C-e +Move to the end of the line. +@item M-f +Move forward a word, where a word is composed of letters and digits. +@item M-b +Move backward a word. +@item C-l +Clear the screen, reprinting the current line at the top. +@end table + +Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves +forward a word. It is a loose convention that control keystrokes +operate on characters while meta keystrokes operate on words. + +@node Readline Killing Commands +@subsection Readline Killing Commands + +@cindex killing text +@cindex yanking text + +@dfn{Killing} text means to delete the text from the line, but to save +it away for later use, usually by @dfn{yanking} (re-inserting) +it back into the line. +(`Cut' and `paste' are more recent jargon for `kill' and `yank'.) + +If the description for a command says that it `kills' text, then you can +be sure that you can get the text back in a different (or the same) +place later. + +When you use a kill command, the text is saved in a @dfn{kill-ring}. +Any number of consecutive kills save all of the killed text together, so +that when you yank it back, you get it all. The kill +ring is not line specific; the text that you killed on a previously +typed line is available to be yanked back later, when you are typing +another line. +@cindex kill ring + +Here is the list of commands for killing text. + +@table @kbd +@item C-k +Kill the text from the current cursor position to the end of the line. + +@item M-d +Kill from the cursor to the end of the current word, or, if between +words, to the end of the next word. +Word boundaries are the same as those used by @kbd{M-f}. + +@item M-@key{DEL} +Kill from the cursor the start of the current word, or, if between +words, to the start of the previous word. +Word boundaries are the same as those used by @kbd{M-b}. + +@item C-w +Kill from the cursor to the previous whitespace. This is different than +@kbd{M-@key{DEL}} because the word boundaries differ. + +@end table + +Here is how to @dfn{yank} the text back into the line. Yanking +means to copy the most-recently-killed text from the kill buffer. + +@table @kbd +@item C-y +Yank the most recently killed text back into the buffer at the cursor. + +@item M-y +Rotate the kill-ring, and yank the new top. You can only do this if +the prior command is @kbd{C-y} or @kbd{M-y}. +@end table + +@node Readline Arguments +@subsection Readline Arguments + +You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the @i{sign} of the +argument that is significant. If you pass a negative argument to a +command which normally acts in a forward direction, that command will +act in a backward direction. For example, to kill text back to the +start of the line, you might type @samp{M-- C-k}. + +The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first `digit' typed is a minus +sign (@samp{-}), then the sign of the argument will be negative. Once +you have typed one meta digit to get the argument started, you can type +the remainder of the digits, and then the command. For example, to give +the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}, +which will delete the next ten characters on the input line. + +@node Searching +@subsection Searching for Commands in the History + +Readline provides commands for searching through the command history +@ifset BashFeatures +(@pxref{Bash History Facilities}) +@end ifset +for lines containing a specified string. +There are two search modes: @dfn{incremental} and @dfn{non-incremental}. + +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, Readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +To search backward in the history for a particular string, type +@kbd{C-r}. Typing @kbd{C-s} searches forward through the history. +The characters present in the value of the @code{isearch-terminators} variable +are used to terminate an incremental search. +If that variable has not been assigned a value, the @key{ESC} and +@kbd{C-J} characters will terminate an incremental search. +@kbd{C-g} will abort an incremental search and restore the original line. +When the search is terminated, the history entry containing the +search string becomes the current line. + +To find other matching entries in the history list, type @kbd{C-r} or +@kbd{C-s} as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a Readline command will terminate +the search and execute that command. +For instance, a @key{RET} will terminate the search and accept +the line, thereby executing the command from the history list. +A movement command will terminate the search, make the last line found +the current line, and begin editing. + +Readline remembers the last incremental search string. If two +@kbd{C-r}s are typed without any intervening characters defining a new +search string, any remembered search string is used. + +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. + +@node Readline Init File +@section Readline Init File +@cindex initialization file, readline + +Although the Readline library comes with a set of Emacs-like +keybindings installed by default, it is possible to use a different set +of keybindings. +Any user can customize programs that use Readline by putting +commands in an @dfn{inputrc} file, conventionally in his home directory. +The name of this +@ifset BashFeatures +file is taken from the value of the shell variable @env{INPUTRC}. If +@end ifset +@ifclear BashFeatures +file is taken from the value of the environment variable @env{INPUTRC}. If +@end ifclear +that variable is unset, the default is @file{~/.inputrc}. + +When a program which uses the Readline library starts up, the +init file is read, and the key bindings are set. + +In addition, the @code{C-x C-r} command re-reads this init file, thus +incorporating any changes that you might have made to it. + +@menu +* Readline Init File Syntax:: Syntax for the commands in the inputrc file. + +* Conditional Init Constructs:: Conditional key bindings in the inputrc file. + +* Sample Init File:: An example inputrc file. +@end menu + +@node Readline Init File Syntax +@subsection Readline Init File Syntax + +There are only a few basic constructs allowed in the +Readline init file.

The default value is @code{emacs}. +The value of the @code{editing-mode} variable also affects the +default keymap. + +@item mark-directories +If set to @samp{on}, completed directory names have a slash +appended. The default is @samp{on}. + +@item mark-modified-lines +@vindex mark-modified-lines +This variable, when set to @samp{on}, causes Readline to display an +asterisk (@samp{*}) at the start of history lines which have been modified. +This variable is @samp{off} by default. + +@item mark-symlinked-directories +@vindex mark-symlinked-directories +If set to @samp{on}, completed names which are symbolic links +to directories have a slash appended (subject to the value of +@code{mark-directories}). +The default is @samp{off}. + +@item match-hidden-files +@vindex match-hidden-files +This variable, when set to @samp{on}, causes Readline to match files whose +names begin with a @samp{.} (hidden files) when performing filename +completion, unless the leading @samp{.} is +supplied by the user in the filename to be completed. +This variable is @samp{on} by default. + +@item output-meta +@vindex output-meta +If set to @samp{on}, Readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. The default is @samp{off}. + +@item page-completions +@vindex page-completions +If set to @samp{on}, Readline uses an internal @code{more}-like pager +to display a screenful of possible completions at a time. +This variable is @samp{on} by default. + +@item print-completions-horizontally +If set to @samp{on}, Readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +The default is @samp{off}. + +@item show-all-if-ambiguous +@vindex show-all-if-ambiguous +This alters the default behavior of the completion functions. If +set to @samp{on}, +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +The default value is @samp{off}. + +@item visible-stats +@vindex visible-stats +If set to @samp{on}, a character denoting a file's type +is appended to the filename when listing possible +completions. The default is @samp{off}. + +@end table + +@item Key Bindings +The syntax for controlling key bindings in the init file is +simple. First you need to find the name of the command that you +want to change. The following sections contain tables of the command +name, the default keybinding, if any, and a short description of what +the command does. + +Once you know the name of the command, simply place on a line +in the init file the name of the key +you wish to bind the command to, a colon, and then the name of the +command. The name of the key +can be expressed in different ways, depending on what you find most +comfortable. + +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a @var{macro}). + +@ifset BashFeatures +The @w{@code{bind -p}} command displays Readline function names and +bindings in a format that can put directly into an initialization file. +@xref{Bash Builtins}. +@end ifset + +@table @asis +@item @w{@var{keyname}: @var{function-name} or @var{macro}} +@var{keyname} is the name of a key spelled out in English.

There are four parser directives used. + +@table @code +@item $if +The @code{$if} construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +Readline. The text of the test extends to the end of the line; +no characters are required to isolate it. + +@table @code +@item mode +The @code{mode=} form of the @code{$if} directive is used to test +whether Readline is in @code{emacs} or @code{vi} mode. +This may be used in conjunction +with the @samp{set keymap} command, for instance, to set bindings in +the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if +Readline is starting out in @code{emacs} mode. + +@item term +The @code{term=} form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +@samp{=} is tested against both the full name of the terminal and +the portion of the terminal name before the first @samp{-}. This +allows @code{sun} to match both @code{sun} and @code{sun-cmd}, +for instance. + +@item application +The @var{application} construct is used to include +application-specific settings. Each program using the Readline +library sets the @var{application name}, and you can test for +a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +@example +$if Bash +# Quote the current or previous word +"\C-xq": "\eb\"\ef\"" +$endif +@end example +@end table + +@item $endif +This command, as seen in the previous example, terminates an +@code{$if} command. + +@item $else +Commands in this branch of the @code{$if} directive are executed if +the test fails. + +@item $include +This directive takes a single filename as an argument and reads commands +and bindings from that file. +For example, the following directive reads from @file{/etc/inputrc}: +@example +$include /etc/inputrc +@end example +@end table + +@node Sample Init File +@subsection Sample Init File + +Here is an example of an @var{inputrc} file.

the function or command has complete freedom in generating +the matches. + +Any function specified with @option{-F} is invoked first. +The function may use any of the shell facilities, including the +@code{compgen} builtin described below +(@pxref{Programmable Completion Builtins}), to generate the matches. +It must put the possible completions in the @env{COMPREPLY} array +variable. + +Next, any command specified with the @option{-C} option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to +the standard output. +Backslash may be used to escape a newline, if necessary. + +After all of the possible completions are generated, any filter +specified with the @option{-X} option is applied to the list. +The filter is a pattern as used for pathname expansion; a @samp{&} +in the pattern is replaced with the text of the word being completed. +A literal @samp{&} may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading @samp{!} negates the pattern; in this case any completion +not matching the pattern will be removed. + +Finally, any prefix and suffix specified with the @option{-P} and @option{-S} +options are added to each member of the completion list, and the result is +returned to the Readline completion code as the list of possible +completions. + +If the previously-applied actions do not generate any matches, and the +@option{-o dirnames} option was supplied to @code{complete} when the +compspec was defined, directory name completion is attempted. + +By default, if a compspec is found, whatever it generates is returned to +the completion code as the full set of possible completions. +The default Bash completions are not attempted, and the Readline default +of filename completion is disabled. +If the @option{-o default} option was supplied to @code{complete} when the +compspec was defined, Readline's default completion will be performed +if the compspec generates no matches. + +When a compspec indicates that directory name completion is desired, +the programmable completion functions force Readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the @var{mark-directories} Readline variable, regardless +of the setting of the @var{mark-symlinked-directories} Readline variable. + +@node Programmable Completion Builtins +@section Programmable Completion Builtins +@cindex completion builtins + +Two builtin commands are available to manipulate the programmable completion +facilities. + +@table @code +@item compgen +@btindex compgen +@example +@code{compgen [@var{option}] [@var{word}]} +@end example + +Generate possible completion matches for @var{word} according to +the @var{option}s, which may be any option accepted by the +@code{complete} +builtin with the exception of @option{-p} and @option{-r}, and write +the matches to the standard output. +When using the @option{-F} or @option{-C} options, the various shell variables +set by the programmable completion facilities, while available, will not +have useful values. + +The matches will be generated in the same way as if the programmable +completion code had generated them directly from a completion specification +with the same flags. +If @var{word} is specified, only those completions matching @var{word} +will be displayed. + +The return value is true unless an invalid option is supplied, or no +matches were generated. + +@item complete +@btindex complete +@example +@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}] +[-P @var{prefix}] [-S @var{suffix}] [-X @var{filterpat}] [-F @var{function}] +[-C @var{command}] @var{name} [@var{name} @dots{}]} +@code{complete -pr [@var{name} @dots{}]} +@end example + +Specify how arguments to each @var{name} should be completed. +If the @option{-p} option is supplied, or if no options are supplied, existing +completion specifications are printed in a way that allows them to be +reused as input. +The @option{-r} option removes a completion specification for +each @var{name}, or, if no @var{name}s are supplied, all +completion specifications. + +The process of applying these completion specifications when word completion +is attempted is described above (@pxref{Programmable Completion}). + +Other options, if specified, have the following meanings. +The arguments to the @option{-G}, @option{-W}, and @option{-X} options +(and, if necessary, the @option{-P} and @option{-S} options) +should be quoted to protect them from expansion before the +@code{complete} builtin is invoked. + + +@table @code +@item -o @var{comp-option} +The @var{comp-option} controls several aspects of the compspec's behavior +beyond the simple generation of completions. +@var{comp-option} may be one of: + +@table @code + +@item default +Use Readline's default filename completion if the compspec generates +no matches. + +@item dirnames +Perform directory name completion if the compspec generates no matches. + +@item filenames +Tell Readline that the compspec generates filenames, so it can perform any +filename\-specific processing (like adding a slash to directory names or +suppressing trailing spaces).

Specifically, I've been using the perl +version Term::ReadLine::Gnu. It works great. + +Anyway, I've been playing around the alternate interface and I wanted +to contribute a little C program, callback.c, to you that you could +use as an example of the alternate interface in the /examples +directory of the readline distribution. + +My example shows how, using the alternate interface, you can +interactively change the prompt (which is very nice imo). Also, I +point out that you must roll your own terminal setting when using the +alternate interface because readline depreps (using your parlance) the +terminal while in the user callback. I try to demostrate what I mean +with an example. I've included the program below. + +To compile, I just put the program in the examples directory and made +the appropriate changes to the EXECUTABLES and OBJECTS line and added +an additional target 'callback'. + +I compiled on my Sun Solaris2.6 box using Sun's cc. + +Let me know what you think. + +Jeff +*/ + +#if defined (HAVE_CONFIG_H) +#include <config.h> +#endif + +#include <stdio.h> +#include <sys/types.h> + +#ifdef HAVE_UNISTD_H +#include <unistd.h> +#endif + +#include <termios.h> /* xxx - should make this more general */ + +#ifdef READLINE_LIBRARY +# include "readline.h" +#else +# include <readline/readline.h> +#endif + +/* This little examples demonstrates the alternate interface to using readline. + * In the alternate interface, the user maintains control over program flow and + * only calls readline when STDIN is readable. Using the alternate interface, + * you can do anything else while still using readline (like talking to a + * network or another program) without blocking. + * + * Specifically, this program highlights two importants features of the + * alternate interface. The first is the ability to interactively change the + * prompt, which can't be done using the regular interface since rl_prompt is + * read-only. + * + * The second feature really highlights a subtle point when using the alternate + * interface. That is, readline will not alter the terminal when inside your + * callback handler. So let's so, your callback executes a user command that + * takes a non-trivial amount of time to complete (seconds). While your + * executing the command, the user continues to type keystrokes and expects them + * to be re-echoed on the new prompt when it returns. Unfortunately, the default + * terminal configuration doesn't do this. After the prompt returns, the user + * must hit one additional keystroke and then will see all of his previous + * keystrokes. To illustrate this, compile and run this program. Type "sleep" at + * the prompt and then type "bar" before the prompt returns (you have 3 + * seconds). Notice how "bar" is re-echoed on the prompt after the prompt + * returns? This is what you expect to happen. Now comment out the 4 lines below + * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do + * the same thing. When the prompt returns, you should not see "bar". Now type + * "f", see how "barf" magically appears?
