Changes to Readline -a. The `make install' target was corrected so that it did not move the - newly-installed libreadline.a to libhistory.old +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. 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. +b. Fixed a typo in the `make install' recipe that copied libreadline.a + to libhistory.old right after installing it. -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. +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. Fixed a problem with the paren matching code -- the blink was far too - short (it's specified in microseconds, not milliseconds, Chet!). +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 --git a/readline/MANIFEST b/readline/MANIFEST index e9e1c4005f9..f23ff41aff8 100644 --- a/readline/MANIFEST +++ b/readline/MANIFEST @@ -4,6 +4,7 @@ doc d examples d support d +shlib d COPYING f README f MANIFEST f @@ -27,6 +28,7 @@ posixstat.h f readline.h f rlconf.h f rldefs.h f +rlstdc.h f rltty.h f rlwinsize.h f tcap.h f @@ -45,6 +47,7 @@ nls.c f parens.c f readline.c f rltty.c f +savestring.c f search.c f shell.c f signals.c f @@ -60,13 +63,17 @@ 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 doc/Makefile.in f doc/texinfo.tex f +doc/manvers.texinfo f doc/rlman.texinfo f doc/rltech.texinfo f doc/rluser.texinfo f @@ -81,5 +88,16 @@ examples/fileman.c f examples/manexamp.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/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 --git a/readline/Makefile.in b/readline/Makefile.in index ae402fd047d..5c667ed69f5 100644 --- a/readline/Makefile.in +++ b/readline/Makefile.in @@ -28,13 +28,15 @@ INSTALL_PROGRAM = @INSTALL_PROGRAM@ INSTALL_DATA = @INSTALL_DATA@ CC = @CC@ -LD = ld # needed when building shared libraries RANLIB = @RANLIB@ -AR = ar +AR = @AR@ +ARFLAGS = @ARFLAGS@ RM = rm -f CP = cp MV = mv +SHELL = @MAKE_SHELL@ + prefix = @prefix@ exec_prefix = @exec_prefix@ @@ -47,8 +49,6 @@ infodir = @infodir@ man3dir = $(mandir)/man3 -SHELL = /bin/sh - # Programs to make tags files.

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.

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 (@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 ()}). + +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 state, 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.
