+This document details the changes between this version, readline-5.1,
+and the previous version, readline-5.0.
+
+1. Changes to Readline
+
+a. Fixed a bug that caused multiliine prompts to be wrapped and displayed
+ incorrectly.
+
+b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
+ line correctly.
+
+c. Fixed a problem in computing the number of invisible characters on the first
+ line of a prompt whose length exceeds the screen width.
+
+d. Fixed vi-mode searching so that failure preserves the current line rather
+ than the last line in the history list.
+
+e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at
+ end-of-line when manipulating multibyte characters.
+
+f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at
+ end-of-line when manipulating multibyte characters.
+
+g. Fixed multiple bugs in the redisplay of multibyte characters: displaying
+ prompts longer than the screen width containing multibyte characters,
+
+h. Fix the calculation of the number of physical characters in the prompt
+ string when it contains multibyte characters.
+
+i. A non-zero value for the `rl_complete_suppress_append' variable now causes
+ no `/' to be appended to a directory name.
+
+j. Fixed forward-word and backward-word to work when words contained
+ multibyte characters.
+
+k. Fixed a bug in finding the delimiter of a `?' substring when performing
+ history expansion in a locale that supports multibyte characters.
+
+l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+ of the `convert-meta' variable.
+
+n. Fixed saving and restoring primary prompt when prompting for incremental
+ and non-incremental searches; search prompts now display multibyte
+ characters correctly.
+
+o. Fixed a bug that caused keys originally bound to self-insert but shadowed
+ by a multi-character key sequence to not be inserted.
+
+p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+ dereferenced if NULL (matching the documentation).
+
+q. Extensive changes to readline to add enough state so that commands
+ requiring additional characters (searches, multi-key sequences, numeric
+ arguments, commands requiring an additional specifier character like
+ vi-mode change-char, etc.) work without synchronously waiting for
+ additional input.
+
+r. Lots of changes so readline builds and runs on MinGW.
+
+s. Readline no longer tries to modify the terminal settings when running in
+ callback mode.
+
+t. The Readline display code no longer sets the location of the last invisible
+ character in the prompt if the \[\] sequence is empty.
+
+u. The `change-case' command now correctly changes the case of multibyte
+ characters.
+
+v. Changes to the shared library construction scripts to deal with Windows
+ DLL naming conventions for Cygwin.
+
+w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
+ SIGWINCH.
+
+x. Fixed the non-incremental search code in vi mode to dispose of any current
+ undo list when copying a line from the history into the current editing
+ buffer.
+
+y. Fixed a bug that caused reversing the incremental search direction to
+ not work correctly.
+
+z. Fixed the vi-mode `U' command to only undo up to the first time insert mode
+ was entered, as Posix specifies.
+
+aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
+ place.
+
+bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
+ with invisible characters in the prompt in a multibyte locale.
+
+cc. Fixed a bug that could cause the terminal special chars to be bound in the
+ wrong keymap in vi mode.
+
+2. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. If the rl_completion_query_items is set to a value < 0, readline never
+ asks the user whether or not to view the possible completions.
+
+f. The `C-w' binding in incremental search now understands multibyte
+ characters.
+
+g. New application-callable auxiliary function, rl_variable_value, returns
+ a string corresponding to a readline variable's value.
+
+h. When parsing inputrc files and variable binding commands, the parser
+ strips trailing whitespace from values assigned to boolean variables
+ before checking them.
+
+i. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.0,
+and the previous version, readline-4.3.
+
+1. Changes to Readline
+
+a. Fixes to avoid core dumps because of null pointer references in the
+ multibyte character code.
+
+b. Fix to avoid infinite recursion caused by certain key combinations.
+
+c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
+
+d. Readline no longer tries to read ahead more than one line of input, even
+ when more is available.
+
+e. Fixed the code that adjusts the point to not mishandle null wide
+ characters.
+
+f. Fixed a bug in the history expansion `g' modifier that caused it to skip
+ every other match.
+
+g. Fixed a bug that caused the prompt to overwrite previous output when the
+ output doesn't contain a newline and the locale supports multibyte
+ characters. This same change fixes the problem of readline redisplay
+ slowing down dramatically as the line gets longer in multibyte locales.
+
+h. History traversal with arrow keys in vi insertion mode causes the cursor
+ to be placed at the end of the new line, like in emacs mode.
+
+i. The locale initialization code does a better job of using the right
+ precedence and defaulting when checking the appropriate environment
+ variables.
+
+j. Fixed the history word tokenizer to handle <( and >( better when used as
+ part of bash.
+
+k. The overwrite mode code received several bug fixes to improve undo.
+
+l. Many speedups to the multibyte character redisplay code.
+
+m. The callback character reading interface should not hang waiting to read
+ keyboard input.
+
+n. Fixed a bug with redoing vi-mode `s' command.
+
+o. The code that initializes the terminal tracks changes made to the terminal
+ special characters with stty(1) (or equivalent), so that these changes
+ are reflected in the readline bindings. New application-callable function
+ to make it work: rl_tty_unset_default_bindings().
+
+p. Fixed a bug that could cause garbage to be inserted in the buffer when
+ changing character case in vi mode when using a multibyte locale.
+
+q. Fixed a bug in the redisplay code that caused problems on systems
+ supporting multibyte characters when moving between history lines when the
+ new line has more glyphs but fewer bytes.
+
+r. Undo and redo now work better after exiting vi insertion mode.
+
+s. Make sure system calls are restarted after a SIGWINCH is received using
+ SA_RESTART.
+
+t. Improvements to the code that displays possible completions when using
+ multibyte characters.
+
+u. Fixed a problem when parsing nested if statements in inputrc files.
+
+v. The completer now takes multibyte characters into account when looking for
+ quoted substrings on which to perform completion.
+
+w. The history search functions now perform better bounds checking on the
+ history list.
+
+x. Change to history expansion functions to treat `^' as equivalent to word
+ one, as the documention states.
+
+y. Some changes to the display code to improve display and redisplay of
+ multibyte characters.
+
+z. Changes to speed up the multibyte character redisplay code.
+
+aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
+ last character of a word if invoked while point was on the word's
+ next-to-last character.
+
+bb. Fixed a bug that could cause incorrect filename quoting when
+ case-insensitive completion was enabled and the word being completed
+ contained backslashes quoting word break characters.
+
+cc. Fixed a bug in redisplay triggered when the prompt string contains
+ invisible characters.
+
+dd. Fixed some display (and other) bugs encountered in multibyte locales
+ when a non-ascii character was the last character on a line.
+
+ee. Fixed some display bugs caused by multibyte characters in prompt strings.
+
+ff. Fixed a problem with history expansion caused by non-whitespace characters
+ used as history word delimiters.
+
+gg. Fixed a problem that could cause readline to refer to freed memory when
+ moving between history lines while doing searches.
+
+hh. Improvements to the code that expands and displays prompt strings
+ containing multibyte characters.
+
+ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
+ to the last `c'hange command for later use with `.'.
+
+jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work
+ incorrectly.
+
+kk. Fixed a problem in vi-mode that caused the last text modification command
+ to not be remembered across different command lines.
+
+ll. Fixed problems with changing characters and changing case at the end of
+ the line.
+
+mm. Fixed a problem with readline saving the contents of the current line
+ before beginning a non-interactive search.
+
+nn. Fixed a problem with EOF detection when using rl_event_hook.
+
+oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+ arguments.
+
+2. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+ rl_bind_key_if_unbound()
+ rl_bind_key_if_unbound_in_map()
+ rl_bind_keyseq_if_unbound()
+ rl_bind_keyseq_if_unbound_in_map()
+
+i. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+j. New application variable, rl_completion_suppress_quote, settable by an
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+
+k. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+l. New function hook, rl_completion_word_break_hook, called when readline
+ needs to break a line into words when completion is attempted. Allows
+ the word break characters to vary based on position in the line.
+
+m. New bindable command: unix-filename-rubout. Does the same thing as
+ unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.

+SHLIB_DLLVERSION The version number for shared libraries that determines API

+SHLIB_DOT The character used to separate the name of the shared library

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.

+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,

-History Interactively}.

-@node Introduction to History
-@section Introduction to History
-
-Many programs read input from the user a line at a time. The @sc{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.
-
-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 @dfn{expansion} function
-is available which provides for a consistent user interface across
-different programs.
-
-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 similar to
-the history substitution provided by @code{csh}.
-
-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.
-
-Before declaring any functions using any functionality the History
-library provides in other code, an application writer should include
-the file @code{<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.
-
-@node History Storage
-@section History Storage
-
-The history list is an array of history entries. A history entry is
-declared as follows:
-
-@example
-typedef void *histdata_t;
-
-typedef struct _hist_entry @{
- char *line;
- histdata_t data;
-@} HIST_ENTRY;
-@end example
-
-The history list itself might therefore be declared as
-
-@example
-HIST_ENTRY **the_history_list;
-@end example
-
-The state of the History library is encapsulated into a single structure:
-
-@example
-/*
- * 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;
-@end example
-
-If the flags member includes @code{HS_STIFLED}, the history has been
-stifled.
-
-@node History Functions
-@section History Functions
-

-exported by the @sc{gnu} History library.

-@cindex command history
-@cindex history list
-
-When the @option{-o history} option to the @code{set} builtin
-is enabled (@pxref{The Set Builtin}),
-the shell provides access to the @dfn{command history},
-the list of commands previously typed.
-The value of the @env{HISTSIZE} shell variable is used as the
-number of commands to save in a history list.
-The text of the last @env{$HISTSIZE}
-commands (default 500) is saved.
-The shell stores each command in the history list prior to
-parameter and variable expansion
-but after history expansion is performed, subject to the
-values of the shell variables
-@env{HISTIGNORE} and @env{HISTCONTROL}.
-
-When the shell starts up, the history is initialized from the
-file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
-The file named by the value of @env{HISTFILE} is truncated, if
-necessary, to contain no more than the number of lines specified by
-the value of the @env{HISTFILESIZE} variable.
-When an interactive shell exits, the last
-@env{$HISTSIZE} lines are copied from the history list to the file
-named by @env{$HISTFILE}.
-If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
-the lines are appended to the history file,
-otherwise the history file is overwritten.
-If @env{HISTFILE}
-is unset, or if the history file is unwritable, the history is
-not saved. After saving the history, the history file is truncated
-to contain no more than @env{$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 may be combined
-with the other options to replace the history list completely.
-
-@item -d @var{offset}
-Delete the history entry at position @var{offset}.
-@var{offset} should be specified as it appears when the history is
-displayed.
-
-@item -a
-Append the new
-history lines (history lines entered since the beginning of the
-current Bash session) to the history file.
-
-@item -n
-Append the history lines not already read from the history file
-to the current history list. These are lines appended to the history
-file since the beginning of the current Bash session.
-
-@item -r
-Read the current history file and append its contents to
-the history list.
-
-@item -w
-Write out the current history to the history file.
-
-@item -p
-Perform history substitution on the @var{arg}s and display the result
-on the standard output, without storing the results in the history list.
-
-@item -s
-The @var{arg}s are added to the end of
-the history list as a single entry.
-
-@end table
-
-When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
-used, if @var{filename}
-is given, then it is used as the history file. If not, then
-the value of the @env{HISTFILE} variable is used.
-
-@end table
-@end ifset
-
-@node History Interaction
-@section History Expansion
-@cindex history expansion
-
-The History library provides a history expansion feature that is similar
-to the history expansion provided by @code{csh}. 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.

-
-@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. This is a synonym for @samp{!-1}.
-
-@item @code{!@var{string}}
-Refer to the most recent command starting with @var{string}.
-
-@item @code{!?@var{string}[?]}
-Refer to the most recent command containing @var{string}. The trailing
-@samp{?} may be omitted if the @var{string} is followed immediately by
-a newline.
-
-@item @code{^@var{string1}^@var{string2}^}
-Quick Substitution. Repeat the last command, replacing @var{string1}
-with @var{string2}. Equivalent to
-@code{!!:s/@var{string1}/@var{string2}/}.
-

-@end table
-
-@node Word Designators
-@subsection Word Designators
-
-Word designators are used to select desired words from the event.
-A @samp{:} separates the event specification from the word designator. It
-may be omitted if the word designator begins with a @samp{^}, @samp{$},
-@samp{*}, @samp{-}, or @samp{%}. Words are numbered from the beginning
-of the line, with the first word being denoted by 0 (zero). Words are
-inserted into the current line separated by single spaces.
-
-@need 0.75
-For example,
-
-@table @code
-@item !!
-designates the preceding command. When you type this, the preceding
-command is repeated in toto.
-
-@item !!:$
-designates the last argument of the preceding command. This may be
-shortened to @code{!$}.
-
-@item !fi:2
-designates the second argument of the most recent command starting with
-the letters @code{fi}.
-@end table
-
-@need 0.75
-Here are the word designators:
-
-@table @code
-
-@item 0 (zero)
-The @code{0}th word. For many applications, this is the command word.
-
-@item @var{n}
-The @var{n}th word.
-
-@item ^
-The first argument; that is, word 1.
-
-@item $
-The last argument.
-
-@item %
-The word matched by the most recent @samp{?@var{string}?} search.
-
-@item @var{x}-@var{y}
-A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
-
-@item *
-All of the words, except the @code{0}th. This is a synonym for @samp{1-$}.
-It is not an error to use @samp{*} if there is just one word in the event;
-the empty string is returned in that case.
-
-@item @var{x}*
-Abbreviates @samp{@var{x}-$}
-
-@item @var{x}-
-Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
-
-@end table
-
-If a word designator is supplied without an event specification, the
-previous command is used as the event.
-
-@node Modifiers
-@subsection Modifiers
-
-After the optional word designator, you can add a sequence of one or more
-of the following modifiers, each preceded by a @samp{:}.
-
-@table @code
-
-@item h
-Remove a trailing pathname component, leaving only the head.
-
-@item t
-Remove all leading pathname components, leaving the tail.
-
-@item r
-Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
-the basename.
-
-@item e
-Remove all but the trailing suffix.
-
-@item p
-Print the new command but do not execute it.
-
-@ifset BashFeatures
-@item q
-Quote the substituted words, escaping further substitutions.
-
-@item x
-Quote the substituted words as with @samp{q},
-but break into words at spaces, tabs, and newlines.
-@end ifset
-
-@item s/@var{old}/@var{new}/
-Substitute @var{new} for the first occurrence of @var{old} in the
-event line. Any delimiter may be used in place of @samp{/}.
-The delimiter may be quoted in @var{old} and @var{new}
-with a single backslash. If @samp{&} appears in @var{new},
-it is replaced by @var{old}. A single backslash will quote
-the @samp{&}. The final delimiter is optional if it is the last
-character on the input line.
-
-@item &
-Repeat the previous substitution.
-
-@item g
-Cause changes to be applied over the entire event line. Used in
-conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
-or with @samp{&}.

-such as completion, line editing, and interactive history manipulation

-
-@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}.
-

-* 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

-@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. You are welcome to modify the
-contents of the line, but see @ref{Allowing Undoing}. The
-function @code{rl_extend_line_buffer} is available to increase
-the memory allocated to @code{rl_line_buffer}.
-@end deftypevar
-
-@deftypevar int rl_point
-The offset of the current cursor position in @code{rl_line_buffer}
-(the @emph{point}).
-@end deftypevar

-@deftypevar int rl_end
-The number of characters present in @code{rl_line_buffer}. When
-@code{rl_point} is at the end of the line, @code{rl_point} and
-@code{rl_end} are equal.
-@end deftypevar
-
-@deftypevar int rl_mark
-The @var{mark} (saved position) in the current line. If set, the mark
-and point define a @emph{region}.

-@node Function Naming
-@subsection Naming a Function
-
-The user can dynamically change the bindings of keys while using
-Readline. This is done by representing the function with a descriptive
-name. The user is able to type the descriptive name when referring to
-the function. Thus, in an init file, one might find
-
-@example
-Meta-Rubout: backward-kill-word
-@end example
-
-This binds the keystroke @key{Meta-Rubout} to the function
-@emph{descriptively} named @code{backward-kill-word}. You, as the
-programmer, should bind the functions you write to descriptive names as
-well. Readline provides a function for doing that:
-
-@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
-Add @var{name} to the list of named functions. Make @var{function} be
-the function that gets called. If @var{key} is not -1, then bind it to
-@var{function} using @code{rl_bind_key()}.
-@end deftypefun
-
-Using this function alone is sufficient for most applications. It is
-the recommended way to add a few functions to the default functions that
-Readline has built in. If you need to do something other
-than adding a function to Readline, you may need to use the
-underlying functions described below.
-
-@node Keymaps
-@subsection Selecting a Keymap
-
-Key bindings take place on a @dfn{keymap}. The keymap is the
-association between the keys that the user types and the functions that
-get run. You can make your own keymaps, copy existing keymaps, and tell
-Readline which keymap to use.
-
-@deftypefun Keymap rl_make_bare_keymap (void)
-Returns a new, empty keymap. The space for the keymap is allocated with
-@code{malloc()}; the caller should free it by calling
-@code{rl_discard_keymap()} when done.
-@end deftypefun
-
-@deftypefun Keymap rl_copy_keymap (Keymap map)
-Return a new keymap which is a copy of @var{map}.
-@end deftypefun
-
-@deftypefun Keymap rl_make_keymap (void)
-Return a new keymap with the printing characters bound to rl_insert,
-the lowercase Meta characters bound to run their equivalents, and
-the Meta digits bound to produce numeric arguments.
-@end deftypefun
-
-@deftypefun void rl_discard_keymap (Keymap keymap)
-Free the storage associated with @var{keymap}.
-@end deftypefun
-
-Readline has several internal keymaps. These functions allow you to
-change which keymap is active.
-
-@deftypefun Keymap rl_get_keymap (void)
-Returns the currently active keymap.
-@end deftypefun
-
-@deftypefun void rl_set_keymap (Keymap keymap)
-Makes @var{keymap} the currently active keymap.
-@end deftypefun
-
-@deftypefun Keymap rl_get_keymap_by_name (const char *name)
-Return the keymap matching @var{name}. @var{name} is one which would
-be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
-@end deftypefun
-
-@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
-Return the name matching @var{keymap}. @var{name} is one which would
-be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
-@end deftypefun
-
-@node Binding Keys
-@subsection Binding Keys
-
-Key sequences are associate with functions through the keymap.
-Readline has several internal keymaps: @code{emacs_standard_keymap},
-@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
-@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
-@code{emacs_standard_keymap} is the default, and the examples in
-this manual assume that.
-
-Since @code{readline()} installs a set of default key bindings the first
-time it is called, there is always the danger that a custom binding
-installed before the first call to @code{readline()} will be overridden.
-An alternate mechanism is to install custom key bindings in an
-initialization function assigned to the @code{rl_startup_hook} variable
-(@pxref{Readline Variables}).
-
-These functions manage key bindings.
-
-@deftypefun int rl_bind_key (int key, rl_command_func_t *function)
-Binds @var{key} to @var{function} in the currently active keymap.
-Returns non-zero in the case of an invalid @var{key}.
-@end deftypefun
-
-@deftypefun int rl_bind_key_in_map (int key, rl_command_func_t *function, Keymap map)
-Bind @var{key} to @var{function} in @var{map}. Returns non-zero in the case
-of an invalid @var{key}.
-@end deftypefun
-
-@deftypefun int rl_unbind_key (int key)
-Bind @var{key} to the null function in the currently active keymap.
-Returns non-zero in case of error.
-@end deftypefun
-
-@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
-Bind @var{key} to the null function in @var{map}.

-@end deftypefun
-
-@deftypefun int rl_set_key (const char *keyseq, rl_command_func_t *function, Keymap map)
-Bind the key sequence represented by the string @var{keyseq} to the function
-@var{function}. This makes new keymaps as
-necessary. The initial keymap in which to do bindings is @var{map}.
-@end deftypefun
-
-@deftypefun int rl_generic_bind (int type, const char *keyseq, char *data, Keymap map)
-Bind the key sequence represented by the string @var{keyseq} to the arbitrary
-pointer @var{data}. @var{type} says what kind of data is pointed to by
-@var{data}; this can be a function (@code{ISFUNC}), a macro
-(@code{ISMACR}), or a keymap (@code{ISKMAP}). This makes new keymaps as
-necessary. The initial keymap in which to do bindings is @var{map}.
-@end deftypefun
-
-@deftypefun int rl_parse_and_bind (char *line)

-@end deftypefun
-
-@node Allowing Undoing
-@subsection Allowing Undoing
-
-Supporting the undo command is a painless thing, and makes your
-functions much more useful. It is certainly easy to try
-something if you know you can undo it.
-
-If your function simply inserts text once, or deletes text once, and
-uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
-undoing is already done for you automatically.
-
-If you do multiple insertions or multiple deletions, or any combination
-of these operations, you should group them together into one operation.
-This is done with @code{rl_begin_undo_group()} and
-@code{rl_end_undo_group()}.
-
-The types of events that can be undone are:
-
-@smallexample
-enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @};
-@end smallexample
-
-Notice that @code{UNDO_DELETE} means to insert some text, and
-@code{UNDO_INSERT} means to delete some text. That is, the undo code
-tells what to undo, not how to undo it. @code{UNDO_BEGIN} and
-@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
-@code{rl_end_undo_group()}.
-
-@deftypefun int rl_begin_undo_group (void)
-Begins saving undo information in a group construct. The undo
-information usually comes from calls to @code{rl_insert_text()} and
-@code{rl_delete_text()}, but could be the result of calls to
-@code{rl_add_undo()}.
-@end deftypefun
-
-@deftypefun int rl_end_undo_group (void)
-Closes the current undo group started with @code{rl_begin_undo_group
-()}. There should be one call to @code{rl_end_undo_group()}
-for each call to @code{rl_begin_undo_group()}.
-@end deftypefun
-
-@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
-Remember how to undo an event (according to @var{what}). The affected
-text runs from @var{start} to @var{end}, and encompasses @var{text}.
-@end deftypefun
-
-@deftypefun void rl_free_undo_list (void)
-Free the existing undo list.
-@end deftypefun
-
-@deftypefun int rl_do_undo (void)
-Undo the first thing on the undo list. Returns @code{0} if there was
-nothing to undo, non-zero if something was undone.
-@end deftypefun
-
-Finally, if you neither insert nor delete text, but directly modify the
-existing text (e.g., change its case), call @code{rl_modifying()}
-once, just before you modify the text. You must supply the indices of
-the text range that you are going to modify.
-
-@deftypefun int rl_modifying (int start, int end)
-Tell Readline to save the text between @var{start} and @var{end} as a
-single undo unit. It is assumed that you will subsequently modify
-that text.

-@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 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)

-@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
-should be called before @code{rl_cleanup_after_signal()}. The

-current input line.
-@end deftypefun

-@deftypefun void rl_reset_after_signal (void)

-is received.

-@node How Completing Works
-@subsection How Completing Works
-
-In order to complete some text, the full list of possible completions
-must be available. 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. You have supplied the function
-that does the initial simple matching selection algorithm (see
-@code{rl_completion_matches()}). The default is to do filename completion.
-@end deftypefun
-
-@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
-This is a pointer to the generator function for
-@code{rl_completion_matches()}.
-If the value of @code{rl_completion_entry_function} is
-@code{NULL} then the default filename generator
-function, @code{rl_filename_completion_function()}, is used.
-@end deftypevar
-
-@node Completion Functions
-@subsection Completion Functions
-
-Here is the complete list of callable completion functions present in
-Readline.
-
-@deftypefun int rl_complete_internal (int what_to_do)
-Complete the word at or before point. @var{what_to_do} says what to do
-with the completion. A value of @samp{?} means list the possible
-completions. @samp{TAB} means do standard completion. @samp{*} means
-insert all of the possible completions. @samp{!} means to display
-all of the possible completions, if there is more than one, as well as
-performing partial completion.
-@end deftypefun
-
-@deftypefun int rl_complete (int ignore, int invoking_key)
-Complete the word at or before point. You have supplied the function
-that does the initial simple matching selection algorithm (see
-@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
-The default is to do filename
-completion. This calls @code{rl_complete_internal()} with an
-argument depending on @var{invoking_key}.
-@end deftypefun
-
-@deftypefun int rl_possible_completions (int count, int invoking_key)
-List the possible completions. See description of @code{rl_complete
-()}. This calls @code{rl_complete_internal()} with an argument of
-@samp{?}.
-@end deftypefun
-
-@deftypefun int rl_insert_completions (int count, int invoking_key)
-Insert the list of possible completions into the line, deleting the
-partially-completed word. See description of @code{rl_complete()}.
-This calls @code{rl_complete_internal()} with an argument of @samp{*}.
-@end deftypefun
-
-@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
-Returns the apppriate value to pass to @code{rl_complete_internal()}
-depending on whether @var{cfunc} was called twice in succession and
-the value of the @code{show-all-if-ambiguous} variable.
-Application-specific completion functions may use this function to present
-the same interface as @code{rl_complete()}.
-@end deftypefun
-
-@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
-Returns an array of strings which is a list of completions for
-@var{text}. If there are no completions, returns @code{NULL}.
-The first entry in the returned array is the substitution for @var{text}.
-The remaining entries are the possible completions. The array is
-terminated with a @code{NULL} pointer.
-
-@var{entry_func} is a function of two args, and returns a
-@code{char *}. The first argument is @var{text}. The second is a
-state argument; it is zero on the first call, and non-zero on subsequent
-calls. @var{entry_func} returns a @code{NULL} pointer to the caller
-when there are no more matches.
-@end deftypefun
-
-@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
-A generator function for filename completion in the general case.
-@var{text} is a partial filename.
-The Bash source is a useful reference for writing custom
-completion functions (the Bash completion functions call this and other
-Readline functions).
-@end deftypefun
-
-@deftypefun {char *} rl_username_completion_function (const char *text, int state)
-A completion generator for usernames. @var{text} contains a partial
-username preceded by a random character (usually @samp{~}). As with all
-completion generators, @var{state} is zero on the first call and non-zero
-for subsequent calls.
-@end deftypefun

-@node Completion Variables
-@subsection Completion Variables
-
-@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
-A pointer to the generator function for @code{rl_completion_matches()}.
-@code{NULL} means to use @code{rl_filename_completion_function()}, the default
-filename completer.
-@end deftypevar
-
-@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
-A pointer to an alternative function to create matches.
-The function is called with @var{text}, @var{start}, and @var{end}.
-@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
-the boundaries of @var{text}, which is a character string.
-If this function exists and returns @code{NULL}, or if this variable is
-set to @code{NULL}, then @code{rl_complete()} will call the value of
-@code{rl_completion_entry_function} to generate matches, otherwise the
-array of strings returned will be used.
-If this function sets the @code{rl_attempted_completion_over}
-variable to a non-zero value, Readline will not perform its default
-completion even if this function returns no matches.
-@end deftypevar
-
-@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
-A pointer to a function that will quote a filename in an
-application-specific fashion. This is called if filename completion is being
-attempted and one of the characters in @code{rl_filename_quote_characters}
-appears in a completed filename. The function is called with
-@var{text}, @var{match_type}, and @var{quote_pointer}. The @var{text}
-is the filename to be quoted. The @var{match_type} is either
-@code{SINGLE_MATCH}, if there is only one completion match, or
-@code{MULT_MATCH}. Some functions use this to decide whether or not to
-insert a closing quote character. The @var{quote_pointer} is a pointer
-to any opening quote character the user typed. Some functions choose
-to reset this character.
-@end deftypevar
-
-@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
-A pointer to a function that will remove application-specific quoting
-characters from a filename before completion is attempted, so those
-characters do not interfere with matching the text against names in
-the filesystem. It is called with @var{text}, the text of the word
-to be dequoted, and @var{quote_char}, which is the quoting character
-that delimits the filename (usually @samp{'} or @samp{"}). If
-@var{quote_char} is zero, the filename was not in an embedded string.
-@end deftypevar

-@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
-A pointer to a function to call that determines whether or not a specific
-character in the line buffer is quoted, according to whatever quoting
-mechanism the program calling Readline uses. The function is called with
-two arguments: @var{text}, the text of the line, and @var{index}, the
-index of the character in the line. It is used to decide whether a
-character found in @code{rl_completer_word_break_characters} should be
-used to break words for the completer.
-@end deftypevar
-
-@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
-This function, if defined, is called by the completer when real filename
-completion is done, after all the matching names have been generated.
-It is passed a @code{NULL} terminated array of matches.
-The first element (@code{matches[0]}) is the
-maximal substring common to all matches. This function can
-re-arrange the list of matches as required, but each element deleted
-from the array must be freed.
-@end deftypevar
-
-@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
-This function, if defined, is allowed to modify the directory portion
-of filenames Readline completes. It is called with the address of a
-string (the current directory name) as an argument, and may modify that string.
-If the string is replaced with a new string, the old value should be freed.
-Any modified directory name should have a trailing slash.
-The modified value will be displayed as part of the completion, replacing
-the directory portion of the pathname the user typed.
-It returns an integer that should be non-zero if the function modifies
-its directory argument.
-It could be used to expand symbolic links or shell variables in pathnames.
-@end deftypevar
-
-@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
-If non-zero, then this is the address of a function to call when
-completing a word would normally display the list of possible matches.
-This function is called in lieu of Readline displaying the list.
-It takes three arguments:
-(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
-where @var{matches} is the array of matching strings,
-@var{num_matches} is the number of strings in that array, and
-@var{max_length} is the length of the longest string in that array.
-Readline provides a convenience function, @code{rl_display_match_list},
-that takes care of doing the display to Readline's output stream. That
-function may be called from this hook.
-@end deftypevar
-
-@deftypevar {const char *} rl_basic_word_break_characters
-The basic list of characters that signal a break between words for the
-completer routine. The default value of this variable is the characters
-which break words for completion in Bash:
-@code{" \t\n\"\\'`@@$><=;|&@{("}.
-@end deftypevar
-
-@deftypevar {const char *} rl_basic_quote_characters
-A list of quote characters which can cause a word break.
-@end deftypevar
-
-@deftypevar {const char *} rl_completer_word_break_characters
-The list of characters that signal a break between words for
-@code{rl_complete_internal()}. The default list is the value of
-@code{rl_basic_word_break_characters}.
-@end deftypevar
-
-@deftypevar {const char *} rl_completer_quote_characters
-A list of characters which can be used to quote a substring of the line.
-Completion occurs on the entire substring, and within the substring
-@code{rl_completer_word_break_characters} are treated as any other character,
-unless they also appear within this list.
-@end deftypevar
-
-@deftypevar {const char *} rl_filename_quote_characters
-A list of characters that cause a filename to be quoted by the completer
-when they appear in a completed filename. The default is the null string.
-@end deftypevar
-
-@deftypevar {const char *} rl_special_prefixes
-The list of characters that are word break characters, but should be
-left in @var{text} when it is passed to the completion function.
-Programs can use this to help determine what kind of completing to do.
-For instance, Bash sets this variable to "$@@" so that it can complete
-shell variables and hostnames.
-@end deftypevar
-
-@deftypevar int rl_completion_query_items
-Up to this many items will be displayed in response to a
-possible-completions call. After that, we ask the user if she is sure
-she wants to see them all. The default value is 100.
-@end deftypevar
-
-@deftypevar {int} rl_completion_append_character
-When a single completion alternative matches at the end of the command
-line, this character is appended to the inserted completion text. The
-default is a space character (@samp{ }). Setting this to the null
-character (@samp{\0}) prevents anything being appended automatically.
-This can be changed in custom completion functions to
-provide the ``most sensible word separator character'' according to
-an application-specific command line syntax specification.
-@end deftypevar
-
-@deftypevar int rl_completion_suppress_append
-If non-zero, @var{rl_completion_append_character} is not appended to
-matches at the end of the command line, as described above. It is
-set to 0 before any application-specific completion function is called.
-@end deftypevar
-
-@deftypevar int rl_completion_mark_symlink_dirs
-If non-zero, a slash will be appended to completed filenames that are
-symbolic links to directory names, subject to the value of the
-user-settable @var{mark-directories} variable.
-This variable exists so that application completion functions can
-override the user's global preference (set via the
-@var{mark-symlinked-directories} Readline variable) if appropriate.
-This variable is set to the user's preference before any
-application completion function is called, so unless that function
-modifies the value, the user's preferences are honored.
-@end deftypevar
-
-@deftypevar int rl_ignore_completion_duplicates
-If non-zero, then duplicates in the matches are removed.
-The default is 1.
-@end deftypevar
-
-@deftypevar int rl_filename_completion_desired
-Non-zero means that the results of the matches are to be treated as
-filenames. This is @emph{always} zero on entry, and can only be changed
-within a completion entry generator function. If it is set to a non-zero
-value, directory names have a slash appended and Readline attempts to
-quote completed filenames if they contain any characters in
-@code{rl_filename_quote_characters} and @code{rl_filename_quoting_desired}
-is set to a non-zero value.
-@end deftypevar
-
-@deftypevar int rl_filename_quoting_desired
-Non-zero means that the results of the matches are to be quoted using
-double quotes (or an application-specific quoting mechanism) if the
-completed filename contains any characters in
-@code{rl_filename_quote_chars}. This is @emph{always} non-zero
-on entry, and can only be changed within a completion entry generator
-function. The quoting is effected via a call to the function pointed to
-by @code{rl_filename_quoting_function}.
-@end deftypevar
-
-@deftypevar int rl_attempted_completion_over
-If an application-specific completion function assigned to
-@code{rl_attempted_completion_function} sets this variable to a non-zero
-value, Readline will not perform its default filename completion even
-if the application's completion function returns no matches.
-It should be set only by an application's completion function.
-@end deftypevar
-
-@deftypevar int rl_completion_type
-Set to a character describing the type of completion Readline is currently
-attempting; see the description of @code{rl_complete_internal()}
-(@pxref{Completion Functions}) for the list of characters.
-@end deftypevar
-
-@deftypevar int rl_inhibit_completion
-If this variable is non-zero, completion is inhibited. The completion
-character will be inserted as any other bound to @code{self-insert}.

-@node Introduction and Notation
-@section Introduction to Line Editing
-
-The following paragraphs describe the notation used to represent
-keystrokes.
-
-The text @kbd{C-k} is read as `Control-K' and describes the character
-produced when the @key{k} key is pressed while the Control key
-is depressed.
-
-The text @kbd{M-k} is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the @key{k}
-key is pressed.
-The Meta key is labeled @key{ALT} on many keyboards.
-On keyboards with two keys labeled @key{ALT} (usually to either side of
-the space bar), the @key{ALT} on the left side is generally set to
-work as a Meta key.
-The @key{ALT} key on the right may also be configured to work as a
-Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-If you do not have a Meta or @key{ALT} key, or another key working as
-a Meta key, the identical keystroke can be generated by typing @key{ESC}
-@emph{first}, and then typing @key{k}.
-Either process is known as @dfn{metafying} the @key{k} key.
-
-The text @kbd{M-C-k} is read as `Meta-Control-k' and describes the
-character produced by @dfn{metafying} @kbd{C-k}.
-
-In addition, several keys have their own names. 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.

-@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.

-@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. Blank lines are ignored.
-Lines beginning with a @samp{#} are comments.
-Lines beginning with a @samp{$} indicate conditional
-constructs (@pxref{Conditional Init Constructs}). Other lines
-denote variable settings and key bindings.
-
-@table @asis
-@item Variable Settings
-You can modify the run-time behavior of Readline by
-altering the values of variables in Readline
-using the @code{set} command within the init file.
-The syntax is simple:
-
-@example
-set @var{variable} @var{value}
-@end example
-
-@noindent
-Here, for example, is how to
-change from the default Emacs-like key binding to use
-@code{vi} line editing commands:
-
-@example
-set editing-mode vi
-@end example
-
-Variable names and values, where appropriate, are recognized without regard
-to case.
-
-@ifset BashFeatures
-The @w{@code{bind -V}} command lists the current Readline variable names
-and values. @xref{Bash Builtins}.
-@end ifset
-
-A great deal of run-time behavior is changeable with the following
-variables.
-
-@cindex variables, readline
-@table @code
-
-@item bell-style
-@vindex bell-style
-Controls what happens when Readline wants to ring the terminal bell.
-If set to @samp{none}, Readline never rings the bell. If set to
-@samp{visible}, Readline uses a visible bell if one is available.
-If set to @samp{audible} (the default), Readline attempts to ring
-the terminal's bell.
-
-@item comment-begin
-@vindex comment-begin
-The string to insert at the beginning of the line when the
-@code{insert-comment} command is executed. The default value
-is @code{"#"}.
-
-@item completion-ignore-case
-If set to @samp{on}, Readline performs filename matching and completion
-in a case-insensitive fashion.
-The default value is @samp{off}.
-
-@item completion-query-items
-@vindex completion-query-items
-The number of possible completions that determines when the user is
-asked whether he wants to see the list of possibilities. If the
-number of possible completions is greater than this value,
-Readline will ask the user whether or not he wishes to view
-them; otherwise, they are simply listed.
-This variable must be set to an integer value greater than or equal to 0.
-The default limit is @code{100}.
-
-@item convert-meta
-@vindex convert-meta
-If set to @samp{on}, Readline will convert characters with the
-eighth bit set to an @sc{ascii} key sequence by stripping the eighth
-bit and prefixing an @key{ESC} character, converting them to a
-meta-prefixed key sequence. The default value is @samp{on}.
-
-@item disable-completion
-@vindex disable-completion
-If set to @samp{On}, Readline will inhibit word completion.
-Completion characters will be inserted into the line as if they had
-been mapped to @code{self-insert}. The default is @samp{off}.
-
-@item editing-mode
-@vindex editing-mode
-The @code{editing-mode} variable controls which default set of
-key bindings is used. By default, Readline starts up in Emacs editing
-mode, where the keystrokes are most similar to Emacs. This variable can be
-set to either @samp{emacs} or @samp{vi}.
-
-@item enable-keypad
-@vindex enable-keypad
-When set to @samp{on}, Readline will try to enable the application
-keypad when it is called. Some systems need this to enable the
-arrow keys. The default is @samp{off}.
-
-@item expand-tilde
-@vindex expand-tilde
-If set to @samp{on}, tilde expansion is performed when Readline
-attempts word completion. The default is @samp{off}.
-
-@vindex history-preserve-point
-If set to @samp{on}, the history code attempts to place point at the
-same location on each history line retrived with @code{previous-history}
-or @code{next-history}.
-
-@item horizontal-scroll-mode
-@vindex horizontal-scroll-mode
-This variable can be set to either @samp{on} or @samp{off}. Setting it
-to @samp{on} means that the text of the lines being edited will scroll
-horizontally on a single screen line when they are longer than the width
-of the screen, instead of wrapping onto a new screen line. By default,
-this variable is set to @samp{off}.
-
-@item input-meta
-@vindex input-meta
-@vindex meta-flag
-If set to @samp{on}, Readline will enable eight-bit input (it
-will not clear the eighth bit in the characters it reads),
-regardless of what the terminal claims it can support. The
-default value is @samp{off}. The name @code{meta-flag} is a
-synonym for this variable.
-
-@item isearch-terminators
-@vindex isearch-terminators
-The string of characters that should terminate an incremental search without
-subsequently executing the character as a command (@pxref{Searching}).
-If this variable has not been given a value, the characters @key{ESC} and
-@kbd{C-J} will terminate an incremental search.
-
-@item keymap
-@vindex keymap
-Sets Readline's idea of the current keymap for key binding commands.
-Acceptable @code{keymap} names are
-@code{emacs},
-@code{emacs-standard},
-@code{emacs-meta},
-@code{emacs-ctlx},
-@code{vi},
-@code{vi-move},
-@code{vi-command}, and
-@code{vi-insert}.
-@code{vi} is equivalent to @code{vi-command}; @code{emacs} is
-equivalent to @code{emacs-standard}. 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. For example:
-@example
-Control-u: universal-argument
-Meta-Rubout: backward-kill-word
-Control-o: "> output"
-@end example
-
-In the above example, @kbd{C-u} is bound to the function
-@code{universal-argument},
-@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and
-@kbd{C-o} is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-@samp{> output} into the line).
-
-A number of symbolic character names are recognized while
-processing this key binding syntax:
-@var{DEL},
-@var{ESC},
-@var{ESCAPE},
-@var{LFD},
-@var{NEWLINE},
-@var{RET},
-@var{RETURN},
-@var{RUBOUT},
-@var{SPACE},
-@var{SPC},
-and
-@var{TAB}.
-
-@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
-@var{keyseq} differs from @var{keyname} above in that strings
-denoting an entire key sequence can be specified, by placing
-the key sequence in double quotes. Some @sc{gnu} Emacs style key
-escapes can be used, as in the following example, but the
-special character names are not recognized.
-
-@example
-"\C-u": universal-argument
-"\C-x\C-r": re-read-init-file
-"\e[11~": "Function Key 1"
-@end example
-
-In the above example, @kbd{C-u} is again bound to the function
-@code{universal-argument} (just as it was in the first example),
-@samp{@kbd{C-x} @kbd{C-r}} is bound to the function @code{re-read-init-file},
-and @samp{@key{ESC} @key{[} @key{1} @key{1} @key{~}} is bound to insert
-the text @samp{Function Key 1}.
-
-@end table
-
-The following @sc{gnu} Emacs style escape sequences are available when
-specifying key sequences:
-
-@table @code
-@item @kbd{\C-}
-control prefix
-@item @kbd{\M-}
-meta prefix
-@item @kbd{\e}
-an escape character
-@item @kbd{\\}
-backslash
-@item @kbd{\"}
-@key{"}, a double quotation mark
-@item @kbd{\'}
-@key{'}, a single quote or apostrophe
-@end table
-
-In addition to the @sc{gnu} Emacs style escape sequences, a second
-set of backslash escapes is available:
-
-@table @code
-@item \a
-alert (bell)
-@item \b
-backspace
-@item \d
-delete
-@item \f
-form feed
-@item \n
-newline
-@item \r
-carriage return
-@item \t
-horizontal tab
-@item \v
-vertical tab
-@item \@var{nnn}
-the eight-bit character whose value is the octal value @var{nnn}
-(one to three digits)
-@item \x@var{HH}
-the eight-bit character whose value is the hexadecimal value @var{HH}
-(one or two hex digits)
-@end table
-
-When entering the text of a macro, single or double quotes must
-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 @samp{"} and @samp{'}.
-For example, the following binding will make @samp{@kbd{C-x} \}
-insert a single @samp{\} into the line:
-@example
-"\C-x\\": "\\"
-@end example
-
-@end table
-
-@node Conditional Init Constructs
-@subsection Conditional Init Constructs
-
-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.
-
-@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 Specifying Numeric Arguments
-@ftable @code
-
-@item digit-argument (@kbd{M-0}, @kbd{M-1}, @dots{} @kbd{M--})
-Add this digit to the argument already accumulating, or start a new
-argument. @kbd{M--} starts a negative argument.
-
-@item universal-argument ()
-This is another way to specify an argument.
-If this command is followed by one or more digits, optionally with a
-leading minus sign, those digits define the argument.
-If the command is followed by digits, executing @code{universal-argument}
-again ends the numeric argument, but is otherwise ignored.
-As a special case, if this command is immediately followed by a
-character that is neither a digit or minus sign, the argument count
-for the next command is multiplied by four.
-The argument count is initially one, so executing this function the
-first time makes the argument count four, a second time makes the
-argument count sixteen, and so on.
-By default, this is not bound to a key.

-@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 @option{-f} or @option{-d} option is used for filename or
-directory name completion, the shell variable @env{FIGNORE} is
-used to filter the matches.
-@xref{Bash Variables}, for a description of @env{FIGNORE}.
-
-Any completions specified by a filename expansion pattern to the
-@option{-G} option are generated next.
-The words generated by the pattern need not match the word being completed.
-The @env{GLOBIGNORE} shell variable is not used to filter the matches,
-but the @env{FIGNORE} shell variable is used.
-
-Next, the string specified as the argument to the @option{-W} option
-is considered.
-The string is first split using the characters in the @env{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 @option{-F} and @option{-C} options is invoked.
-When the command or function is invoked, the @env{COMP_LINE} and
-@env{COMP_POINT} variables are assigned values as described above
-(@pxref{Bash Variables}).
-If a shell function is being invoked, the @env{COMP_WORDS} and
-@env{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 @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.

-@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). This option is intended to be used with
-shell functions specified with @option{-F}.
-
-@item nospace
-Tell Readline not to append a space (the default) to words completed at
-the end of the line.
-@end table
-
-@item -A @var{action}
-The @var{action} may be one of the following to generate a list of possible
-completions:
-
-@table @code
-@item alias
-Alias names. May also be specified as @option{-a}.
-
-@item arrayvar
-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 @option{-b}.
-
-@item command
-Command names. May also be specified as @option{-c}.
-
-@item directory
-Directory names. May also be specified as @option{-d}.
-
-@item disabled
-Names of disabled shell builtins.
-
-@item enabled
-Names of enabled shell builtins.
-
-@item export
-Names of exported shell variables. May also be specified as @option{-e}.
-
-@item file
-File names. May also be specified as @option{-f}.
-
-@item function
-Names of shell functions.
-
-@item group
-Group names. May also be specified as @option{-g}.
-
-@item helptopic
-Help topics as accepted by the @code{help} builtin (@pxref{Bash Builtins}).
-
-@item hostname
-Hostnames, as taken from the file specified by the
-@env{HOSTFILE} shell variable (@pxref{Bash Variables}).
-
-@item job
-Job names, if job control is active. May also be specified as @option{-j}.
-
-@item keyword
-Shell reserved words. May also be specified as @option{-k}.
-
-@item running
-Names of running jobs, if job control is active.
-
-@item service
-Service names. May also be specified as @option{-s}.
-
-@item setopt
-Valid arguments for the @option{-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 @option{-u}.
-
-@item variable
-Names of all shell variables. May also be specified as @option{-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
-@env{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 @env{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 @option{-p} or @option{-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.

-/* PROBLEMS/TODO:
- *
- * Only tested under Linux; needs to be ported.
- *
- * When running mc -c under the Linux console, mc does not recognize
- * mouse clicks, which mc does when not running under fep.
- *
- * 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.
