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.

Subject: Use of Readline
Reply-to: rms@gnu.org
I think Allbery's suggestion is a good one. So please add this text
in a suitable place. Please don't put it in the GPL itself; that
should be the same as the GPL everywhere else. Putting it in the
README and/or the documentation would be a good idea.
======================================================================
Our position on the use of Readline through a shared-library linking
mechanism is that there is no legal difference between shared-library
linking and static linking--either kind of linking combines various
modules into a single larger work. The conditions for using Readline
in a larger work are stated in section 3 of the GNU GPL.

@node Programmable Completion
@section Programmable Completion
@cindex programmable completion
When word completion is attempted for an argument to a command for
which a completion specification (a @var{compspec}) has been defined
using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
the programmable completion facilities are invoked.
First, the command name is identified.
If a compspec has been defined for that command, the
compspec is used to generate the list of possible completions for the word.
If the command word is a full pathname, a compspec for the full
pathname is searched for first.
If no compspec is found for the full pathname, an attempt is made to
find a compspec for the portion following the final slash.
Once a compspec has been found, it is used to generate the list of
matching words.
If a compspec is not found, the default Bash completion
described above (@pxref{Commands For Completion}) is performed.
First, the actions specified by the compspec are used.
Only matches which are prefixed by the word being completed are
returned.
When the @samp{-f} or @samp{-d} option is used for filename or
directory name completion, the shell variable @code{FIGNORE} is
used to filter the matches.
@xref{Bash Variables}, for a description of @code{FIGNORE}.
Any completions specified by a filename expansion pattern to the
@samp{-G} option are generated next.
The words generated by the pattern need not match the word being completed.
The @code{GLOBIGNORE} shell variable is not used to filter the matches,
but the @code{FIGNORE} shell variable is used.
Next, the string specified as the argument to the @samp{-W} option
is considered.
The string is first split using the characters in the @code{IFS}
special variable as delimiters.
Shell quoting is honored.
Each word is then expanded using
brace expansion, tilde expansion, parameter and variable expansion,
command substitution, arithmetic expansion, and pathname expansion,
as described above (@pxref{Shell Expansions}).
The results are split using the rules described above
(@pxref{Word Splitting}).
The results of the expansion are prefix-matched against the word being
completed, and the matching words become the possible completions.
After these matches have been generated, any shell function or command
specified with the @samp{-F} and @samp{-C} options is invoked.
When the command or function is invoked, the @code{COMP_LINE} and
@code{COMP_POINT} variables are assigned values as described above
(@pxref{Bash Variables}).
If a shell function is being invoked, the @code{COMP_WORDS} and
@code{COMP_CWORD} variables are also set.
When the function or command is invoked, the first argument is the
name of the command whose arguments are being completed, the
second argument is the word being completed, and the third argument
is the word preceding the word being completed on the current command line.
No filtering of the generated completions against the word being completed
is performed; the function or command has complete freedom in generating
the matches.
Any function specified with @samp{-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 @code{COMPREPLY} array
variable.
Next, any command specified with the @samp{-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 @samp{-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 @samp{-P} and @samp{-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 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.
@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 @samp{-p} and @samp{-r}, and write
the matches to the standard output.
When using the @samp{-F} or @samp{-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

@code{complete [-abcdefjkvu] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}]

[-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 @samp{-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 @samp{-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 @samp{-G}, @samp{-W}, and @samp{-X} options
(and, if necessary, the @samp{-P} and @samp{-S} options)

Array variable names.
@item binding
Readline key binding names (@pxref{Bindable Readline Commands}).
@item builtin
Names of shell builtin commands. May also be specified as @samp{-b}.
@item command
Command names. May also be specified as @samp{-c}.
@item directory
Directory names. May also be specified as @samp{-d}.
@item disabled
Names of disabled shell builtins.
@item enabled
Names of enabled shell builtins.

@item hostname
Hostnames, as taken from the file specified by the
@code{HOSTFILE} shell variable (@pxref{Bash Variables}).
@item job
Job names, if job control is active. May also be specified as @samp{-j}.
@item keyword
Shell reserved words. May also be specified as @samp{-k}.
@item running
Names of running jobs, if job control is active.
@item setopt
Valid arguments for the @samp{-o} option to the @code{set} builtin
(@pxref{The Set Builtin}).
@item shopt
Shell option names as accepted by the @code{shopt} builtin
(@pxref{Bash Builtins}).
@item signal
Signal names.
@item stopped
Names of stopped jobs, if job control is active.
@item user
User names. May also be specified as @samp{-u}.
@item variable
Names of all shell variables. May also be specified as @samp{-v}.
@end table
@item -G @var{globpat}
The filename expansion pattern @var{globpat} is expanded to generate
the possible completions.
@item -W @var{wordlist}
The @var{wordlist} is split using the characters in the
@code{IFS} special variable as delimiters, and each resultant word
is expanded.
The possible completions are the members of the resultant list which
match the word being completed.
@item -C @var{command}
@var{command} is executed in a subshell environment, and its output is
used as the possible completions.
@item -F @var{function}
The shell function @var{function} is executed in the current shell
environment.
When it finishes, the possible completions are retrieved from the value
of the @code{COMPREPLY} array variable.
@item -X @var{filterpat}
@var{filterpat} is a pattern as used for filename expansion.
It is applied to the list of possible completions generated by the
preceding options and arguments, and each completion matching
@var{filterpat} is removed from the list.
A leading @samp{!} in @var{filterpat} negates the pattern; in this
case, any completion not matching @var{filterpat} is removed.
@item -P @var{prefix}
@var{prefix} is added at the beginning of each possible completion
after all other options have been applied.
@item -S @var{suffix}
@var{suffix} is appended to each possible completion
after all other options have been applied.
@end table
The return value is true unless an invalid option is supplied, an option
other than @samp{-p} or @samp{-r} is supplied without a @var{name}
argument, an attempt is made to remove a completion specification for
a @var{name} for which no specification exists, or
an error occurs adding a completion specification.

From: Jeff Solomon <jsolomon@stanford.edu>
Date: Fri, 9 Apr 1999 10:13:27 -0700 (PDT)
To: chet@po.cwru.edu
Subject: new readline example
Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
Chet,
I've been using readline 4.0. 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

/* 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? This behavior is un-expected and not
* desired.

* When running mc -c under the Linux console, mc does not recognize

*
* Pasting selected text containing tabs is like hitting the tab character,
* which invokes readline completion. We don't want this. I don't know
* if this is fixable without integrating fep into a terminal emulator.
*
* Echo suppression is a kludge, but can only be avoided with better kernel
* support: We need a tty mode to disable "real" echoing, while still
* letting the inferior think its tty driver to doing echoing.
* Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
*
* The latest readline may have some hooks we can use to avoid having
* to back up the prompt.
*
* Desirable readline feature: When in cooked no-echo mode (e.g. password),
* echo characters are they are types with '*', but remove them when done.
*
* A synchronous output while we're editing an input line should be
* inserted in the output view *before* the input line, so that the
* lines being edited (with the prompt) float at the end of the input.
*
* A "page mode" option to emulate more/less behavior: At each page of
* output, pause for a user command. This required parsing the output
* to keep track of line lengths. It also requires remembering the
* output, if we want an option to scroll back, which suggests that
* this should be integrated with a terminal emulator like xterm.
