This document details the changes between this version, readline-2.2.1,
This document details the changes between this version, readline-4.0,
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
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.

@ -49,32 +49,83 @@ Shared Libraries
================
There is skeletal support for building shared versions of the
Readline and History libraries.
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.
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:
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.
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.
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*'.
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.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
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.
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
Once you have edited Makefile.in, type `make Makefile' to rebuild the
Makefile, then `make shared' to build the shared libraries.
SHOBJ_CFLAGS Flags to pass to the C compiler ($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 provides commands for searching through the com-

There are two search modes: _i_n_c_r_e_m_e_n_t_a_l and _n_o_n_-_i_n_c_r_e_m_e_n_-
_t_a_l.
Incremental searches begin before the user has finished
typing the search string. As each character of the search
string is typed, readline displays the next entry from the
history matching the string typed so far. An incremental
search requires only as many characters as needed to find
the desired history entry. The Escape character is used
to terminate an incremental search. Control-J will also
terminate the search. Control-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 Control-S or Control-R as appro-
priate. This will search backward or forward in the his-
tory 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 _n_e_w_l_i_n_e will terminate the search and accept
the line, thereby executing the command from the history
list.

search requires only as many characters as needed to find
the desired history entry. The characters present in the
value of the _i_s_e_a_r_c_h_-_t_e_r_m_i_n_a_t_o_r_s variable are used to ter-
minate an incremental search. If that variable has not
been assigned a value the Escape and Control-J characters
will terminate an incremental search. Control-G will
abort an incremental search and restore the original line.
When the search is terminated, the history entry contain-
ing the search string becomes the current line. To find
other matching entries in the history list, type Control-S
or Control-R 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

@node Readline Signal Handling
@section 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 (@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. 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). This

Readline signal handler for @code{SIGINT} calls this to abort the
current input line.
@end deftypefun
@deftypefun void rl_reset_after_signal (void)
This will reinitialize the terminal and reinstall any Readline signal
handlers, depending on the values of @code{rl_catch_signals} and

@end deftypefun
If an application does not wish Readline to catch @code{SIGWINCH}, it may
