This document details the changes between this version, readline-2.2.1, and the previous version, readline-2.2. 1. Changes to Readline ! a. The `make install' target was corrected so that it did not move the ! newly-installed libreadline.a to libhistory.old ! b. The `make install' target for the documentation will now install the ! info files from the source directory if they do not appear in the ! build directory, since they are shipped in the readline tar file. ! c. Fixed a problem with redisplay that showed up when the prompt string was ! longer than the screen width and the prompt contained invisible characters. ! d. Fixed a problem with the paren matching code -- the blink was far too ! short (it's specified in microseconds, not milliseconds, Chet!). ! ------------------------------------------------------------------------------ This document details the changes between this version, readline-2.2, and the previous version, readline-2.1. --- 1,130 ---- ! 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. diff -aNrc2 readline-2.2.1/MANIFEST readline-4.0/MANIFEST *** readline-2.2.1/MANIFEST Thu Sep 4 10:47:05 1997 --- readline-4.0/MANIFEST Thu Dec 31 12:07:24 1998 *************** *** 5,8 **** --- 5,9 ---- examples d support d + shlib d COPYING f README f *************** *** 28,31 **** --- 29,33 ---- rlconf.h f rldefs.h f + rlstdc.h f rltty.h f rlwinsize.h f *************** *** 46,49 **** --- 48,52 ---- readline.c f rltty.c f + savestring.c f search.c f shell.c f *************** *** 61,64 **** --- 64,68 ---- histfile.c f histsearch.c f + shlib/Makefile.in f support/config.guess f support/config.sub f *************** *** 66,71 **** --- 70,78 ---- support/mkdirs f support/mkdist f + support/shobj-conf f + support/shlib-install f doc/Makefile.in f doc/texinfo.tex f + doc/manvers.texinfo f doc/rlman.texinfo f doc/rltech.texinfo f *************** *** 82,85 **** --- 89,103 ---- 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/readline.dvi f + doc/history.dvi f + doc/readline.info f + doc/history.info f + doc/readline.html f + doc/history.html f + doc/readline.0 f diff -aNrc2 readline-2.2.1/MANIFEST.doc readline-4.0/MANIFEST.doc *** readline-2.2.1/MANIFEST.doc Thu Apr 16 10:28:49 1998 --- readline-4.0/MANIFEST.doc Wed Dec 31 19:00:00 1969 *************** *** 1,16 **** - # - # Master Manifest file for documentation-only distribution - # - doc d - MANIFEST.doc f - doc/readline.ps f - doc/history.ps f - doc/readline.dvi f - doc/history.dvi f - doc/readline.info f - doc/history.info f - doc/readline.html f - doc/readline_toc.html f - doc/history.html f - doc/history_toc.html f - doc/readline.0 f --- 0 ---- diff -aNrc2 readline-2.2.1/Makefile.in readline-4.0/Makefile.in *** readline-2.2.1/Makefile.in Fri Jul 17 11:00:54 1998 --- readline-4.0/Makefile.in Thu Feb 18 12:24:11 1999 *************** *** 29,39 **** CC = @CC@ - LD = ld # needed when building shared libraries RANLIB = @RANLIB@ !

Examples *************** *** 50,79 **** There is skeletal support for building shared versions of the ! Readline and History libraries. ! ! Typing `make shared' will cause shared versions of the Readline and ! History libraries to be built on SunOS 4.1.x. For versions of Unix ! other than SunOS, you will have to make some changes to Makefile.in. ! The relevant variables are: ! ! PICFLAG Options to give to the compiler to produce position-independent ! code. The value `-fpic' works for most versions of gcc. ! SHLIB_OPTS Options to give to the linker to produce a shared library. ! The value `-assert pure-text -ldl' works on SunOS 4.1.x. ! The value `-Bshareable' works for some versions of GNU ld. ! ! MAJOR The major version number of the shared library. You should ! not need to change this. ! MINOR The minor version number of the shared library. Some systems, ! such as SVR4 and its descendents (e.g., Solaris, Unixware), ! do not use minor version numbers. For those systems, this ! variable should be left unset. ! ! LD The linker. The value of `ld' is correct for SunOS 4.1.x. ! You may need to change it to `gcc'; make sure to change ! SHLIB_OPTS if you do so. ! ! Once you have edited Makefile.in, type `make Makefile' to rebuild the ! Makefile, then `make shared' to build the shared libraries. Documentation --- 50,130 ---- 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. ! ! 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 2.2.5 with any version of gcc is identified as ! `freebsd2.2.5-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. ! ! Since shared libraries are not created on all platforms, `make install' ! will not automatically install the shared libraries. To install them, ! change the current directory to shlib and type `make install'. Running ! `make install-shared' from the top-level build directory will also work.

    Readline Bare Essentials

    +

    + + + + +

    +

    + In order to enter characters into the line, simply type them. The typed + character appears where the cursor was, and then the cursor moves one + space to the right. If you mistype a character, you can use your + erase character to back up and delete the mistyped character. + +

    +

    + Sometimes you may miss typing a character that you wanted to type, and + not notice your error until you have typed several other characters. In + that case, you can type C-b to move the cursor to the left, and then + correct your mistake. Afterwards, you can move the cursor to the right + with C-f. + +

    +

    + When you add text in the middle of a line, you will notice that characters + to the right of the cursor are `pushed over' to make room for the text + that you have inserted. Likewise, when you delete text behind the cursor, + characters to the right of the cursor are `pulled back' to fill in the + blank space created by the removal of the text. A list of the basic bare + essentials for editing the text of an input line follows. + +

    +
    + +
    C-b +
    + Move back one character. +
    C-f +
    + Move forward one character. +
    DEL +
    + Delete the character to the left of the cursor. +
    C-d +
    + Delete the character underneath the cursor. +
    Printing characters +
    + Insert the character into the line at the cursor. +
    C-_ +
    + Undo the last editing command. You can undo all the way back to an + empty line. +
    + + + +

    Readline Movement Commands

    + +

    + The above table describes the most basic possible keystrokes that you need + in order to do editing of the input line. For your convenience, many + other commands have been added in addition to C-b, C-f, + C-d, and DEL. Here are some commands for moving more rapidly + about the line. + +

    +
    + +
    C-a +
    + Move to the start of the line. +
    C-e +
    + Move to the end of the line. +
    M-f +
    + Move forward a word, where a word is composed of letters and digits. +
    M-b +
    + Move backward a word. +
    C-l +
    + Clear the screen, reprinting the current line at the top. +
    + +

    + Notice how C-f moves forward a character, while M-f moves + forward a word. It is a loose convention that control keystrokes + operate on characters while meta keystrokes operate on words. + +

    + + +

    Readline Killing Commands

    + +

    + + + +

    +

    + Killing text means to delete the text from the line, but to save + it away for later use, usually by yanking (re-inserting) + it back into the line. + If the description for a command says that it `kills' text, then you can + be sure that you can get the text back in a different (or the same) + place later. + +

    +

    + When you use a kill command, the text is saved in a kill-ring. + Any number of consecutive kills save all of the killed text together, so + that when you yank it back, you get it all. The kill + ring is not line specific; the text that you killed on a previously + typed line is available to be yanked back later, when you are typing + another line. + + +

    +

    + Here is the list of commands for killing text. + +

    +
    + +
    C-k +
    + Kill the text from the current cursor position to the end of the line. + +
    M-d +
    + Kill from the cursor to the end of the current word, or if between + words, to the end of the next word. + +
    M-DEL +
    + Kill from the cursor the start of the previous word, or if between + words, to the start of the previous word. + +
    C-w +
    + Kill from the cursor to the previous whitespace. This is different than + M-DEL because the word boundaries differ. + +
    + +

    + Here is how to yank the text back into the line. Yanking + means to copy the most-recently-killed text from the kill buffer. + +

    +
    + +
    C-y +
    + Yank the most recently killed text back into the buffer at the cursor. + +
    M-y +
    + Rotate the kill-ring, and yank the new top. You can only do this if + the prior command is C-y or M-y. +
    + + + +

    Readline Arguments

    + +

    + You can pass numeric arguments to Readline commands. Sometimes the + argument acts as a repeat count, other times it is the sign of the + argument that is significant. If you pass a negative argument to a + command which normally acts in a forward direction, that command will + act in a backward direction. For example, to kill text back to the + start of the line, you might type `M-- C-k'. + +

    +

    + The general way to pass numeric arguments to a command is to type meta + digits before the command. If the first `digit' typed is a minus + sign (-), then the sign of the argument will be negative. Once + you have typed one meta digit to get the argument started, you can type + the remainder of the digits, and then the command. For example, to give + the C-d command an argument of 10, you could type `M-1 0 C-d'. + +

    + + +

    Searching for Commands in the History

    + +

    + Readline provides commands for searching through the command history + for lines containing a specified string. + There are two search modes: incremental and non-incremental. + +

    +

    + Incremental searches begin before the user has finished typing the + search string. + As each character of the search string is typed, Readline displays + the next entry from the history matching the string typed so far. + An incremental search requires only as many characters as needed to + find the desired history entry. + The characters present in the value of the isearch-terminators variable + are used to terminate an incremental search. + If that variable has not been assigned a value, the ESC and + C-J characters will terminate an incremental search. + C-g will abort an incremental search and restore the original line. + When the search is terminated, the history entry containing the + search string becomes the current line. + To find other matching entries in the history list, type C-s or + C-r as appropriate. + This will search backward or forward in the history for the next + entry matching the search string typed so far. + Any other key sequence bound to a Readline command will terminate + the search and execute that command. + For instance, a RET will terminate the search and accept + the line, thereby executing the command from the history list. + +

    +

    + 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. +

    Readline Init File

    !

    ! ! !

    !

    ! Although the Readline library comes with a set of emacs-like ! keybindings installed by default, it is possible to use a different set ! of keybindings. ! Any user can customize programs that use Readline by putting ! commands in an inputrc file in his home directory. ! The name of this ! file is taken from the value of the environment variable INPUTRC. If ! that variable is unset, the default is `~/.inputrc'. ! !

    !

    ! When a program which uses the Readline library starts up, the ! init file is read, and the key bindings are set. ! !

    !

    ! In addition, the C-x C-r command re-reads this init file, thus ! incorporating any changes that you might have made to it. ! !

    Readline Signal Handling

    ! !

    ! Signals are asynchronous events sent to a process by the Unix kernel, ! sometimes on behalf of another process. 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 a signal is ! received to restore the terminal to a sane state, or provide application ! writers with functions to do so manually. ! !

    !

    ! Readline contains an internal signal handler that is installed for a ! number of signals (SIGINT, SIGQUIT, SIGTERM, ! SIGALRM, SIGTSTP, SIGTTIN, and SIGTTOU). ! When one of these signals is received, the signal handler ! will reset the terminal attributes to those that were in effect before ! readline () was called, reset the signal handling to what it was ! before readline () was called, and resend the signal to the calling ! application. ! If and when the calling application's signal handler returns, Readline ! will reinitialize the terminal and continue to accept input. ! When a SIGINT is received, the Readline signal handler performs ! some additional work, which will cause any partially-entered line to be ! aborted (see the description of rl_free_line_state ()). ! !

    !

    ! There is an additional Readline signal handler, for SIGWINCH, which ! the kernel sends to a process whenever the terminal's size changes (for ! example, if a user resizes an xterm). The Readline SIGWINCH ! handler updates Readline's internal screen size state, and then calls any ! SIGWINCH signal handler the calling application has installed. ! Readline calls the application's SIGWINCH signal handler without ! resetting the terminal to its original state. If the application's signal ! handler does more than update its idea of the terminal size and return (for ! example, a longjmp back to a main processing loop), it must ! call rl_cleanup_after_signal () (described below), to restore the ! terminal state. ! !

    !

    ! Readline provides two variables that allow application writers to ! control whether or not it will catch certain signals and act on them ! when they are received. It is important that applications change the ! values of these variables only when calling readline (), not in ! a signal handler, so Readline's internal signal state is not corrupted. ! !

    !

    !

    !
    Variable: int rl_catch_signals !
    ! If this variable is non-zero, Readline will install signal handlers for ! SIGINT, SIGQUIT, SIGTERM, SIGALRM, ! SIGTSTP, SIGTTIN, and SIGTTOU. ! !

    !

    ! The default value of rl_catch_signals is 1. !

    ! !

    !

    !

    !
    Variable: int rl_catch_sigwinch !
    ! If this variable is non-zero, Readline will install a signal handler for ! SIGWINCH. ! !

    !

    ! The default value of rl_catch_sigwinch is 1. !

    ! !

    !

    ! If an application does not wish to have Readline catch any signals, or ! to handle signals other than those Readline catches (SIGHUP, ! for example), ! Readline provides convenience functions to do the necessary terminal ! and internal state cleanup upon receipt of a signal. ! !

    !

    !

    !
    Function: void rl_cleanup_after_signal (void) !
    ! This function will reset the state of the terminal to what it was before ! readline () was called, and remove the Readline signal handlers for ! all signals, depending on the values of rl_catch_signals and ! rl_catch_sigwinch. !
    ! !

    !

    !

    !
    Function: void rl_free_line_state (void) !
    ! This will free any partial state associated with the current input line ! (undo information, any partial history entry, any partially-entered ! keyboard macro, and any partially-entered numeric argument). This ! should be called before rl_cleanup_after_signal (). The ! Readline signal handler for SIGINT calls this to abort the ! current input line. !
    ! !

    !

    !

    !
    Function: void rl_reset_after_signal (void) !
    ! This will reinitialize the terminal and reinstall any Readline signal ! handlers, depending on the values of rl_catch_signals and ! rl_catch_sigwinch. !
    ! !

    !

    ! If an application does not wish Readline to catch SIGWINCH, it may ! call rl_resize_terminal () to force Readline to update its idea of ! the terminal size when a SIGWINCH is received. ! !

    !

    !

    !
    Function: void rl_resize_terminal (void) !
    ! Update Readline's internal screen size. !
    ! !

    !

    ! The following functions install and remove Readline's signal handlers. ! !

    !

    !

    !
    Function: int rl_set_signals (void) !
    ! Install Readline's signal handler for SIGINT, SIGQUIT, ! SIGTERM, SIGALRM, SIGTSTP, SIGTTIN, ! SIGTTOU, and SIGWINCH, depending on the values of ! rl_catch_signals and rl_catch_sigwinch. !
    ! !

    !

    !

    !
    Function: int rl_clear_signals (void) !
    ! Remove all of the Readline signal handlers installed by ! rl_set_signals (). !

File: readline.info, Node: Readline Signal Handling, Next: Custom Completers, Prev: Readline Convenience Functions, Up: Programming with GNU Readline ! ! Readline Signal Handling ! ======================== ! ! Signals are asynchronous events sent to a process by the Unix kernel, ! sometimes on behalf of another process. 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 a signal is ! received to restore the terminal to a sane state, or provide application ! writers with functions to do so manually. ! ! Readline contains an internal signal handler that is installed for a ! number of signals (`SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', ! `SIGTSTP', `SIGTTIN', and `SIGTTOU'). When one of these signals is ! received, the signal handler will reset the terminal attributes to ! those that were in effect before `readline ()' was called, reset the ! signal handling to what it was before `readline ()' was called, and ! resend the signal to the calling application. If and when the calling ! application's signal handler returns, Readline will reinitialize the ! terminal and continue to accept input. When a `SIGINT' is received, ! the Readline signal handler performs some additional work, which will ! cause any partially-entered line to be aborted (see the description of ! `rl_free_line_state ()'). ! ! There is an additional Readline signal handler, for `SIGWINCH', which ! the kernel sends to a process whenever the terminal's size changes (for ! example, if a user resizes an `xterm'). The Readline `SIGWINCH' ! handler updates Readline's internal screen size state, and then calls ! any `SIGWINCH' signal handler the calling application has installed. ! Readline calls the application's `SIGWINCH' signal handler without ! resetting the terminal to its original state. If the application's ! signal handler does more than update its idea of the terminal size and ! return (for example, a `longjmp' back to a main processing loop), it ! *must* call `rl_cleanup_after_signal ()' (described below), to restore ! the terminal state. ! ! Readline provides two variables that allow application writers to ! control whether or not it will catch certain signals and act on them ! when they are received. It is important that applications change the ! values of these variables only when calling `readline ()', not in a ! signal handler, so Readline's internal signal state is not corrupted. ! ! - Variable: int rl_catch_signals ! If this variable is non-zero, Readline will install signal ! handlers for `SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', `SIGTSTP', ! `SIGTTIN', and `SIGTTOU'. ! ! The default value of `rl_catch_signals' is 1. ! ! - Variable: int rl_catch_sigwinch ! If this variable is non-zero, Readline will install a signal ! handler for `SIGWINCH'. ! ! The default value of `rl_catch_sigwinch' is 1. ! ! If an application does not wish to have Readline catch any signals, ! or to handle signals other than those Readline catches (`SIGHUP', for ! example), Readline provides convenience functions to do the necessary ! terminal and internal state cleanup upon receipt of a signal. ! ! - Function: void rl_cleanup_after_signal (void) ! This function will reset the state of the terminal to what it was ! before `readline ()' was called, and remove the Readline signal ! handlers for all signals, depending on the values of ! `rl_catch_signals' and `rl_catch_sigwinch'. ! ! - Function: void rl_free_line_state (void) ! This will free any partial state associated with the current input ! line (undo information, any partial history entry, any ! partially-entered keyboard macro, and any partially-entered ! numeric argument). This should be called before ! `rl_cleanup_after_signal ()'. The Readline signal handler for ! `SIGINT' calls this to abort the current input line. ! ! - Function: void rl_reset_after_signal (void) ! This will reinitialize the terminal and reinstall any Readline ! signal handlers, depending on the values of `rl_catch_signals' and ! `rl_catch_sigwinch'. ! ! If an application does not wish Readline to catch `SIGWINCH', it may ! call `rl_resize_terminal ()' to force Readline to update its idea of ! the terminal size when a `SIGWINCH' is received. ! ! - Function: void rl_resize_terminal (void) ! Update Readline's internal screen size. ! ! The following functions install and remove Readline's signal ! handlers. ! ! - Function: int rl_set_signals (void) ! Install Readline's signal handler for `SIGINT', `SIGQUIT', ! `SIGTERM', `SIGALRM', `SIGTSTP', `SIGTTIN', `SIGTTOU', and ! `SIGWINCH', depending on the values of `rl_catch_signals' and ! `rl_catch_sigwinch'. ! ! - Function: int rl_clear_signals (void) ! Remove all of the Readline signal handlers installed by ! `rl_set_signals ()'. ! !  !
