<H2> 1.1 Introduction to Line Editing </H2>
<!--docid::SEC2::-->
<P>

The following paragraphs describe the notation used to represent
keystrokes.
</P><P>

The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
produced when the <KBD>k</KBD> key is pressed while the Control key
is depressed.
</P><P>

The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
key is pressed.
The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
the space bar), the <KBD>ALT</KBD> on the left side is generally set to
work as a Meta key.
The <KBD>ALT</KBD> 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.
</P><P>

If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
<EM>first</EM>, and then typing <KBD>k</KBD>.
Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
</P><P>

The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
</P><P>

In addition, several keys have their own names.  Specifically,
<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
stand for themselves when seen in this text, or in an init file
(see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
produce the desired character.
The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
some keyboards.

<H2> 1.2 Readline Interaction </H2>
<!--docid::SEC3::-->
<P>

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 <KBD>RET</KBD>.  You do not have to be at the
end of the line to press <KBD>RET</KBD>; the entire line is accepted
regardless of the location of the cursor within the line.

<!--docid::SEC4::-->
<P>

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.
</P><P>

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</KBD> 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</KBD>.
</P><P>

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.
</P><P>

<DL COMPACT>
<DT><KBD>C-b</KBD>
<DD>Move back one character.
<DT><KBD>C-f</KBD>
<DD>Move forward one character.

empty line.
</DL>
<P>

(Depending on your configuration, the <KBD>Backspace</KBD> key be set to
delete the character to the left of the cursor and the <KBD>DEL</KBD> key set
to delete the character underneath the cursor, like <KBD>C-d</KBD>, rather
than the character to the left of the cursor.)

<H3> 1.2.2 Readline Movement Commands </H3>
<!--docid::SEC5::-->
<P>

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>, <KBD>C-f</KBD>,
<KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly
about the line.
</P><P>

<DL COMPACT>
<DT><KBD>C-a</KBD>
<DD>Move to the start of the line.
<DT><KBD>C-e</KBD>
<DD>Move to the end of the line.
<DT><KBD>M-f</KBD>
<DD>Move forward a word, where a word is composed of letters and digits.
<DT><KBD>M-b</KBD>
<DD>Move backward a word.
<DT><KBD>C-l</KBD>
<DD>Clear the screen, reprinting the current line at the top.
</DL>
<P>

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

<!--docid::SEC6::-->
<P>

<A NAME="IDX1"></A>
<A NAME="IDX2"></A>
</P><P>

<EM>Killing</EM> text means to delete the text from the line, but to save
it away for later use, usually by <EM>yanking</EM> (re-inserting)
it back into the line.
(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
</P><P>

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.
</P><P>

When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
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.
<A NAME="IDX3"></A>
</P><P>

Here is the list of commands for killing text.
</P><P>

<DL COMPACT>
<DT><KBD>C-k</KBD>
<DD>Kill the text from the current cursor position to the end of the line.
<P>

<DT><KBD>M-d</KBD>
<DD>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</KBD>.
<P>

<DT><KBD>M-<KBD>DEL</KBD></KBD>
<DD>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</KBD>.
<P>

<DT><KBD>C-w</KBD>
<DD>Kill from the cursor to the previous whitespace.  This is different than
<KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ.
<P>

</DL>
<P>

Here is how to <EM>yank</EM> the text back into the line.  Yanking
means to copy the most-recently-killed text from the kill buffer.
</P><P>

<DL COMPACT>
<DT><KBD>C-y</KBD>
<DD>Yank the most recently killed text back into the buffer at the cursor.
<P>

<DT><KBD>M-y</KBD>
<DD>Rotate the kill-ring, and yank the new top.  You can only do this if
the prior command is <KBD>C-y</KBD> or <KBD>M-y</KBD>.

<H3> 1.2.4 Readline Arguments </H3>
<!--docid::SEC7::-->
<P>

You can pass numeric arguments to Readline commands.  Sometimes the
argument acts as a repeat count, other times it is the <I>sign</I> 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'</SAMP>.
</P><P>

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>`-'</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</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
which will delete the next ten characters on the input line.

</TR></TABLE>
<H3> 1.2.5 Searching for Commands in the History </H3>
<!--docid::SEC8::-->
<P>

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

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</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
The characters present in the value of the <CODE>isearch-terminators</CODE> variable
are used to terminate an incremental search.
If that variable has not been assigned a value, the <KBD>ESC</KBD> and
<KBD>C-J</KBD> characters will terminate an incremental search.
<KBD>C-g</KBD> 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.
</P><P>

To find other matching entries in the history list, type <KBD>C-r</KBD> or
<KBD>C-s</KBD> 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 <KBD>RET</KBD> 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.
</P><P>

Readline remembers the last incremental search string.  If two
<KBD>C-r</KBD>s are typed without any intervening characters defining a new
search string, any remembered search string is used.
</P><P>

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.

<H2> 1.3 Readline Init File </H2>
<!--docid::SEC9::-->
<P>

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 <EM>inputrc</EM> file, conventionally in his home directory.
The name of this
file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
that variable is unset, the default is <TT>`~/.inputrc'</TT>.  If that
file does not exist or cannot be read, the ultimate default is
<TT>`/etc/inputrc'</TT>.
</P><P>

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

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

<H3> 1.3.1 Readline Init File Syntax </H3>
<!--docid::SEC10::-->
<P>

There are only a few basic constructs allowed in the
Readline init file.  Blank lines are ignored.
Lines beginning with a <SAMP>`#'</SAMP> are comments.
Lines beginning with a <SAMP>`$'</SAMP> indicate conditional
constructs (see section <A HREF="readline.html#SEC11">1.3.2 Conditional Init Constructs</A>).  Other lines
denote variable settings and key bindings.
</P><P>

<DL COMPACT>
<DT>Variable Settings
<DD>You can modify the run-time behavior of Readline by
altering the values of variables in Readline
using the <CODE>set</CODE> command within the init file.
The syntax is simple:
<P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR>
</pre></td></tr></table></P><P>

Here, for example, is how to
change from the default Emacs-like key binding to use
<CODE>vi</CODE> line editing commands:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>set editing-mode vi
</pre></td></tr></table></P><P>

Variable names and values, where appropriate, are recognized without regard
to case.  Unrecognized variable names are ignored.
</P><P>

Boolean variables (those that can be set to on or off) are set to on if
the value is null or empty, <VAR>on</VAR> (case-insensitive), or 1.  Any other
value results in the variable being set to off.
</P><P>

A great deal of run-time behavior is changeable with the following
variables.
</P><P>

<A NAME="IDX4"></A>
<DL COMPACT>

<DT><CODE>bell-style</CODE>
<DD><A NAME="IDX5"></A>
Controls what happens when Readline wants to ring the terminal bell.
If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
the terminal's bell.
<P>

<DT><CODE>bind-tty-special-chars</CODE>
<DD><A NAME="IDX6"></A>
If set to <SAMP>`on'</SAMP> (the default), Readline attempts to bind the control
characters   treated specially by the kernel's terminal driver to their
Readline equivalents.
<P>

<DT><CODE>blink-matching-paren</CODE>
<DD><A NAME="IDX7"></A>
If set to <SAMP>`on'</SAMP>, Readline attempts to briefly move the cursor to an

environment variable.
The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>comment-begin</CODE>
<DD><A NAME="IDX10"></A>
The string to insert at the beginning of the line when the
<CODE>insert-comment</CODE> command is executed.  The default value
is <CODE>"#"</CODE>.
<P>

<DT><CODE>completion-display-width</CODE>
<DD><A NAME="IDX11"></A>
The number of screen columns used to display possible matches
when performing completion.
The value is ignored if it is less than 0 or greater than the terminal
screen width.
A value of 0 will cause matches to be displayed one per line.
The default value is -1.
<P>

<DT><CODE>completion-ignore-case</CODE>
<DD><A NAME="IDX12"></A>
If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
in a case-insensitive fashion.
The default value is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>completion-map-case</CODE>
<DD><A NAME="IDX13"></A>
If set to <SAMP>`on'</SAMP>, and <VAR>completion-ignore-case</VAR> is enabled, Readline
treats hyphens (<SAMP>`-'</SAMP>) and underscores (<SAMP>`_'</SAMP>) as equivalent when
performing case-insensitive filename matching and completion.
The default value is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>completion-prefix-display-length</CODE>
<DD><A NAME="IDX14"></A>
The length in characters of the common prefix of a list of possible
completions that is displayed without modification.  When set to a
value greater than zero, common prefixes longer than this value are
replaced with an ellipsis when displaying possible completions.
<P>

<DT><CODE>completion-query-items</CODE>
<DD><A NAME="IDX15"></A>
The number of possible completions that determines when the user is
asked whether the list of possibilities should be displayed.
If the number of possible completions is greater than or equal to this value,
Readline will ask whether or not the user wishes to view them;
otherwise, they are simply listed.
This variable must be set to an integer value greater than or equal to 0.
A negative value means Readline should never ask.
The default limit is <CODE>100</CODE>.
<P>

<DT><CODE>convert-meta</CODE>
<DD><A NAME="IDX16"></A>
If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
eighth bit set to an ASCII key sequence by stripping the eighth
bit and prefixing an <KBD>ESC</KBD> character, converting them to a
meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>, but
will be set to <SAMP>`off'</SAMP> if the locale is one that contains
eight-bit characters.
<P>

<DT><CODE>disable-completion</CODE>
<DD><A NAME="IDX17"></A>
If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
Completion  characters will be inserted into the line as if they had
been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>echo-control-characters</CODE>
<DD><A NAME="IDX18"></A>
When set to <SAMP>`on'</SAMP>, on operating systems that indicate they support it,
readline echoes a character corresponding to a signal generated from the
keyboard.  The default is <SAMP>`on'</SAMP>.
<P>

<DT><CODE>editing-mode</CODE>
<DD><A NAME="IDX19"></A>
The <CODE>editing-mode</CODE> 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'</SAMP> or <SAMP>`vi'</SAMP>.
<P>

<DT><CODE>emacs-mode-string</CODE>
<DD><A NAME="IDX20"></A>
If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
this string is displayed immediately before the last line of the primary
prompt when emacs editing mode is active.  The value is expanded like a
key binding, so the standard set of meta- and control prefixes and
backslash escape sequences is available.
Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
non-printing characters, which can be used to embed a terminal control
sequence into the mode string.
The default is <SAMP>`@'</SAMP>.
<P>

<DT><CODE>enable-bracketed-paste</CODE>
<DD><A NAME="IDX21"></A>
When set to <SAMP>`On'</SAMP>, Readline will configure the terminal in a way
that will enable it to insert each paste into the editing buffer as a
single string of characters, instead of treating each character as if
it had been read from the keyboard.  This can prevent pasted characters
from being interpreted as editing commands.  The default is <SAMP>`On'</SAMP>.
<P>

<DT><CODE>enable-keypad</CODE>
<DD><A NAME="IDX22"></A>
When set to <SAMP>`on'</SAMP>, 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'</SAMP>.
<P>

<DT><CODE>enable-meta-key</CODE>
<DD>When set to <SAMP>`on'</SAMP>, Readline will try to enable any meta modifier
key the terminal claims to support when it is called.  On many terminals,
the meta key is used to send eight-bit characters.
The default is <SAMP>`on'</SAMP>.
<P>

<DT><CODE>expand-tilde</CODE>
<DD><A NAME="IDX23"></A>
If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
attempts word completion.  The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>history-preserve-point</CODE>
<DD><A NAME="IDX24"></A>
If set to <SAMP>`on'</SAMP>, the history code attempts to place the point (the
current cursor position) at the
same location on each history line retrieved with <CODE>previous-history</CODE>
or <CODE>next-history</CODE>.  The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>history-size</CODE>
<DD><A NAME="IDX25"></A>
Set the maximum number of history entries saved in the history list.
If set to zero, any existing history entries are deleted and no new entries
are saved.
If set to a value less than zero, the number of history entries is not
limited.
By default, the number of history entries is not limited.
If an attempt is made to set <VAR>history-size</VAR> to a non-numeric value,
the maximum number of history entries will be set to 500.
<P>

<DT><CODE>horizontal-scroll-mode</CODE>
<DD><A NAME="IDX26"></A>
This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
to <SAMP>`on'</SAMP> 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.
This variable is automatically set to <SAMP>`on'</SAMP> for terminals of height 1.
By default, this variable is set to <SAMP>`off'</SAMP>.
<P>

<DT><CODE>input-meta</CODE>
<DD><A NAME="IDX27"></A>
<A NAME="IDX28"></A>
If set to <SAMP>`on'</SAMP>, 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'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the 
locale contains eight-bit characters.
The name <CODE>meta-flag</CODE> is a synonym for this variable.
<P>

<DT><CODE>isearch-terminators</CODE>
<DD><A NAME="IDX29"></A>
The string of characters that should terminate an incremental search without
subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">1.2.5 Searching for Commands in the History</A>).
If this variable has not been given a value, the characters <KBD>ESC</KBD> and
<KBD>C-J</KBD> will terminate an incremental search.
<P>

<DT><CODE>keymap</CODE>
<DD><A NAME="IDX30"></A>
Sets Readline's idea of the current keymap for key binding commands.
Built-in <CODE>keymap</CODE> names are
<CODE>emacs</CODE>,
<CODE>emacs-standard</CODE>,
<CODE>emacs-meta</CODE>,
<CODE>emacs-ctlx</CODE>,
<CODE>vi</CODE>,
<CODE>vi-move</CODE>,
<CODE>vi-command</CODE>, and
<CODE>vi-insert</CODE>.
<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE> (<CODE>vi-move</CODE> is also a
synonym); <CODE>emacs</CODE> is equivalent to <CODE>emacs-standard</CODE>.
Applications may add additional names.
The default value is <CODE>emacs</CODE>.
The value of the <CODE>editing-mode</CODE> variable also affects the
default keymap.
<P>

<DT><CODE>keyseq-timeout</CODE>
<DD>Specifies the duration Readline will wait for a character when reading an
ambiguous key sequence (one that can form a complete key sequence using
the input read so far, or can take additional input to complete a longer
key sequence).
If no input is received within the timeout, Readline will use the shorter
but complete key sequence.
Readline uses this value to determine whether or not input is
available on the current input source (<CODE>rl_instream</CODE> by default).
The value is specified in milliseconds, so a value of 1000 means that
Readline will wait one second for additional input.
If this variable is set to a value less than or equal to zero, or to a
non-numeric value, Readline will wait until another key is pressed to
decide which key sequence to complete.
The default value is <CODE>500</CODE>.
<P>

<DT><CODE>mark-directories</CODE>
<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
appended.  The default is <SAMP>`on'</SAMP>.
<P>

<DT><CODE>mark-modified-lines</CODE>
<DD><A NAME="IDX31"></A>
This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
This variable is <SAMP>`off'</SAMP> by default.
<P>

<DT><CODE>mark-symlinked-directories</CODE>
<DD><A NAME="IDX32"></A>
If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
to directories have a slash appended (subject to the value of
<CODE>mark-directories</CODE>).
The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>match-hidden-files</CODE>
<DD><A NAME="IDX33"></A>
This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
completion.
If set to <SAMP>`off'</SAMP>, the leading <SAMP>`.'</SAMP> must be
supplied by the user in the filename to be completed.
This variable is <SAMP>`on'</SAMP> by default.
<P>

<DT><CODE>menu-complete-display-prefix</CODE>
<DD><A NAME="IDX34"></A>
If set to <SAMP>`on'</SAMP>, menu completion displays the common prefix of the
list of possible completions (which may be empty) before cycling through
the list.  The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>output-meta</CODE>
<DD><A NAME="IDX35"></A>
If set to <SAMP>`on'</SAMP>, Readline will display characters with the
eighth bit set directly rather than as a meta-prefixed escape
sequence.
The default is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the
locale contains eight-bit characters.
<P>

<DT><CODE>page-completions</CODE>
<DD><A NAME="IDX36"></A>
If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
to display a screenful of possible completions at a time.
This variable is <SAMP>`on'</SAMP> by default.
<P>

<DT><CODE>print-completions-horizontally</CODE>
<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
sorted horizontally in alphabetical order, rather than down the screen.
The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>revert-all-at-newline</CODE>
<DD><A NAME="IDX37"></A>
If set to <SAMP>`on'</SAMP>, Readline will undo all changes to history lines
before returning when <CODE>accept-line</CODE> is executed.  By default,
history lines may be modified and retain individual undo lists across
calls to <CODE>readline</CODE>.  The default is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>show-all-if-ambiguous</CODE>
<DD><A NAME="IDX38"></A>
This alters the default behavior of the completion functions.  If
set to <SAMP>`on'</SAMP>, 
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'</SAMP>.
<P>

<DT><CODE>show-all-if-unmodified</CODE>
<DD><A NAME="IDX39"></A>
This alters the default behavior of the completion functions in
a fashion similar to <VAR>show-all-if-ambiguous</VAR>.
If set to <SAMP>`on'</SAMP>, 
words which have more than one possible completion without any
possible partial completion (the possible completions don't share
a common prefix) cause the matches to be listed immediately instead
of ringing the bell.
The default value is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>show-mode-in-prompt</CODE>
<DD><A NAME="IDX40"></A>
If set to <SAMP>`on'</SAMP>, add a string to the beginning of the prompt
indicating the editing mode: emacs, vi command, or vi insertion.
The mode strings are user-settable (e.g., <VAR>emacs-mode-string</VAR>).
The default value is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>skip-completed-text</CODE>
<DD><A NAME="IDX41"></A>
If set to <SAMP>`on'</SAMP>, this alters the default completion behavior when
inserting a single match into the line.  It's only active when
performing completion in the middle of a word.  If enabled, readline
does not insert characters from the completion that match characters
after point in the word being completed, so portions of the word
following the cursor are not duplicated.
For instance, if this is enabled, attempting completion when the cursor
is after the <SAMP>`e'</SAMP> in <SAMP>`Makefile'</SAMP> will result in <SAMP>`Makefile'</SAMP>
rather than <SAMP>`Makefilefile'</SAMP>, assuming there is a single possible
completion.
The default value is <SAMP>`off'</SAMP>.
<P>

<DT><CODE>vi-cmd-mode-string</CODE>
<DD><A NAME="IDX42"></A>
If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
this string is displayed immediately before the last line of the primary
prompt when vi editing mode is active and in command mode.
The value is expanded like a
key binding, so the standard set of meta- and control prefixes and
backslash escape sequences is available.
Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
non-printing characters, which can be used to embed a terminal control
sequence into the mode string.
The default is <SAMP>`(cmd)'</SAMP>.
<P>

<DT><CODE>vi-ins-mode-string</CODE>
<DD><A NAME="IDX43"></A>
If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
this string is displayed immediately before the last line of the primary
prompt when vi editing mode is active and in insertion mode.
The value is expanded like a
key binding, so the standard set of meta- and control prefixes and
backslash escape sequences is available.
Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
non-printing characters, which can be used to embed a terminal control
sequence into the mode string.
The default is <SAMP>`(ins)'</SAMP>.
<P>

<DT><CODE>visible-stats</CODE>
<DD><A NAME="IDX44"></A>
If set to <SAMP>`on'</SAMP>, a character denoting a file's type
is appended to the filename when listing possible
completions.  The default is <SAMP>`off'</SAMP>.
<P>

</DL>
<P>

<DT>Key Bindings
<DD>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.
<P>

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.
There can be no space between the key name and the colon -- that will be
interpreted as part of the key name.
The name of the key can be expressed in different ways, depending on
what you find most comfortable.
</P><P>

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</VAR>).
</P><P>

<DL COMPACT>
<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
<DD><VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>Control-u: universal-argument
Meta-Rubout: backward-kill-word
Control-o: "&#62; output"
</pre></td></tr></table><P>

In the example above, <KBD>C-u</KBD> is bound to the function
<CODE>universal-argument</CODE>,
<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
<KBD>C-o</KBD> is bound to run the macro
expressed on the right hand side (that is, to insert the text
<SAMP>`&#62; output'</SAMP> into the line).
</P><P>

A number of symbolic character names are recognized while
processing this key binding syntax:
<VAR>DEL</VAR>,
<VAR>ESC</VAR>,
<VAR>ESCAPE</VAR>,
<VAR>LFD</VAR>,
<VAR>NEWLINE</VAR>,
<VAR>RET</VAR>,
<VAR>RETURN</VAR>,
<VAR>RUBOUT</VAR>,
<VAR>SPACE</VAR>,
<VAR>SPC</VAR>,
and
<VAR>TAB</VAR>.
</P><P>

<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
<DD><VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
denoting an entire key sequence can be specified, by placing
the key sequence in double quotes.  Some GNU Emacs style key
escapes can be used, as in the following example, but the
special character names are not recognized.
<P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-u": universal-argument
"\C-x\C-r": re-read-init-file
"\e[11~": "Function Key 1"
</pre></td></tr></table></P><P>

In the above example, <KBD>C-u</KBD> is again bound to the function
<CODE>universal-argument</CODE> (just as it was in the first example),
<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
the text <SAMP>`Function Key 1'</SAMP>.
</P><P>

</DL>
<P>

The following GNU Emacs style escape sequences are available when
specifying key sequences:
</P><P>

<DL COMPACT>
<DT><CODE><KBD>\C-</KBD></CODE>
<DD>control prefix
<DT><CODE><KBD>\M-</KBD></CODE>
<DD>meta prefix
<DT><CODE><KBD>\e</KBD></CODE>
<DD>an escape character
<DT><CODE><KBD>\\</KBD></CODE>
<DD>backslash
<DT><CODE><KBD>\"</KBD></CODE>
<DD><KBD>"</KBD>, a double quotation mark
<DT><CODE><KBD>\'</KBD></CODE>
<DD><KBD>'</KBD>, a single quote or apostrophe
</DL>
<P>

In addition to the GNU Emacs style escape sequences, a second
set of backslash escapes is available:
</P><P>

<DL COMPACT>
<DT><CODE>\a</CODE>
<DD>alert (bell)
<DT><CODE>\b</CODE>
<DD>backspace
<DT><CODE>\d</CODE>
<DD>delete
<DT><CODE>\f</CODE>
<DD>form feed
<DT><CODE>\n</CODE>
<DD>newline
<DT><CODE>\r</CODE>
<DD>carriage return
<DT><CODE>\t</CODE>
<DD>horizontal tab
<DT><CODE>\v</CODE>
<DD>vertical tab
<DT><CODE>\<VAR>nnn</VAR></CODE>
<DD>the eight-bit character whose value is the octal value <VAR>nnn</VAR>
(one to three digits)
<DT><CODE>\x<VAR>HH</VAR></CODE>
<DD>the eight-bit character whose value is the hexadecimal value <VAR>HH</VAR>
(one or two hex digits)
</DL>
<P>

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>`"'</SAMP> and <SAMP>`''</SAMP>.
For example, the following binding will make <SAMP>`<KBD>C-x</KBD> \'</SAMP>
insert a single <SAMP>`\'</SAMP> into the line:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-x\\": "\\"

<H3> 1.3.2 Conditional Init Constructs </H3>
<!--docid::SEC11::-->
<P>

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.
</P><P>

<DL COMPACT>
<DT><CODE>$if</CODE>
<DD>The <CODE>$if</CODE> 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, after any comparison operator,
extends to the end of the line;
unless otherwise noted, no characters are required to isolate it.
<P>

<DL COMPACT>
<DT><CODE>mode</CODE>
<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
This may be used in conjunction
with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
Readline is starting out in <CODE>emacs</CODE> mode.
<P>

<DT><CODE>term</CODE>
<DD>The <CODE>term=</CODE> 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>`='</SAMP> is tested against both the full name of the terminal and
the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
for instance.
<P>

<DT><CODE>version</CODE>
<DD>The <CODE>version</CODE> test may be used to perform comparisons against
specific Readline versions.
The <CODE>version</CODE> expands to the current Readline version.
The set of comparison operators includes
<SAMP>`='</SAMP> (and <SAMP>`=='</SAMP>), <SAMP>`!='</SAMP>, <SAMP>`&#60;='</SAMP>, <SAMP>`&#62;='</SAMP>, <SAMP>`&#60;'</SAMP>,
and <SAMP>`&#62;'</SAMP>.
The version number supplied on the right side of the operator consists
of a major version number, an optional decimal point, and an optional
minor version (e.g., <SAMP>`7.1'</SAMP>). If the minor version is omitted, it
is assumed to be <SAMP>`0'</SAMP>.
The operator may be separated from the string <CODE>version</CODE> and
from the version number argument by whitespace.
The following example sets a variable if the Readline version being used
is 7.0 or newer:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if version &#62;= 7.0
set show-mode-in-prompt on
$endif
</pre></td></tr></table><P>

<DT><CODE>application</CODE>
<DD>The <VAR>application</VAR> construct is used to include
application-specific settings.  Each program using the Readline
library sets the <VAR>application name</VAR>, 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:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
# Quote the current or previous word
"\C-xq": "\eb\"\ef\""
$endif
</pre></td></tr></table><P>

<DT><CODE>variable</CODE>
<DD>The <VAR>variable</VAR> construct provides simple equality tests for Readline
variables and values.
The permitted comparison operators are <SAMP>`='</SAMP>, <SAMP>`=='</SAMP>, and <SAMP>`!='</SAMP>.
The variable name must be separated from the comparison operator by
whitespace; the operator may be separated from the value on the right hand
side by whitespace.
Both string and boolean variables may be tested. Boolean variables must be
tested against the values <VAR>on</VAR> and <VAR>off</VAR>.
The following example is equivalent to the <CODE>mode=emacs</CODE> test described
above:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if editing-mode == emacs
set show-mode-in-prompt on
$endif
</pre></td></tr></table></DL>
<P>

<DT><CODE>$endif</CODE>
<DD>This command, as seen in the previous example, terminates an
<CODE>$if</CODE> command.
<P>

<DT><CODE>$else</CODE>
<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
the test fails.
<P>

<DT><CODE>$include</CODE>
<DD>This directive takes a single filename as an argument and reads commands
and bindings from that file.
For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
</pre></td></tr></table></DL>

<DD><A NAME="IDX80"></A>
Search forward starting at the current line and moving `down' through
the history as necessary.  This is an incremental search.
This command sets the region to the matched text and activates the mark.
<P>

<A NAME="IDX81"></A>
<DT><CODE>non-incremental-reverse-search-history (M-p)</CODE>
<DD><A NAME="IDX82"></A>
Search backward starting at the current line and moving `up'

This is a non-incremental search.
By default, this command is unbound.
<P>

<A NAME="IDX87"></A>
<DT><CODE>history-search-backward ()</CODE>
<DD><A NAME="IDX88"></A>
Search backward through the history for the string of characters
between the start of the current line and the point.
The search string must match at the beginning of a history line.
This is a non-incremental search.
By default, this command is unbound.
<P>

<A NAME="IDX89"></A>
<DT><CODE>history-substring-search-forward ()</CODE>
<DD><A NAME="IDX90"></A>

the second word on the previous line) at point.
With an argument <VAR>n</VAR>,
insert the <VAR>n</VAR>th word from the previous command (the words
in the previous command begin with word 0).  A negative argument
inserts the <VAR>n</VAR>th word from the end of the previous command.
Once the argument <VAR>n</VAR> is computed, the argument is extracted
as if the <SAMP>`!<VAR>n</VAR>'</SAMP> history expansion had been specified.
<P>

<A NAME="IDX95"></A>
<DT><CODE>yank-last-arg (M-. or M-_)</CODE>
<DD><A NAME="IDX96"></A>
Insert last argument to the previous command (the last word of the
previous history entry).
With a numeric argument, behave exactly like <CODE>yank-nth-arg</CODE>.
Successive calls to <CODE>yank-last-arg</CODE> move back through the history
list, inserting the last word (or the word specified by the argument to
the first call) of each line in turn.
Any numeric argument supplied to these successive calls determines
the direction to move through the history.  A negative argument switches
the direction through the history (back or forward).
The history expansion facilities are used to extract the last argument,
as if the <SAMP>`!$'</SAMP> history expansion had been specified.
<P>

<A NAME="IDX97"></A>
<DT><CODE>operate-and-get-next (C-o)</CODE>

newline had been entered,
and fetch the next line relative to the current line from the history
for editing.
A numeric argument, if supplied, specifies the history entry to use instead
of the current line.

<H3> 1.4.3 Commands For Changing Text </H3>
<!--docid::SEC16::-->
<P>

<DL COMPACT>

<A NAME="IDX99"></A>
<DT><CODE><I>end-of-file</I> (usually C-d)</CODE>
<DD><A NAME="IDX100"></A>
The character indicating end-of-file as set, for example, by
<CODE>stty</CODE>.  If this character is read when there are no characters
on the line, and point is at the beginning of the line, Readline
interprets it as the end of input and returns EOF.
<P>

<A NAME="IDX101"></A>
<DT><CODE>delete-char (C-d)</CODE>
<DD><A NAME="IDX102"></A>
Delete the character at point.  If this function is bound to the
same character as the tty EOF character, as <KBD>C-d</KBD>
commonly is, see above for the effects.
<P>

<A NAME="IDX103"></A>
<DT><CODE>backward-delete-char (Rubout)</CODE>
<DD><A NAME="IDX104"></A>
Delete the character behind the cursor.  A numeric argument means
to kill the characters instead of deleting them.
<P>

<A NAME="IDX105"></A>
<DT><CODE>forward-backward-delete-char ()</CODE>
<DD><A NAME="IDX106"></A>
Delete the character under the cursor, unless the cursor is at the
end of the line, in which case the character behind the cursor is
deleted.  By default, this is not bound to a key.
<P>

<A NAME="IDX107"></A>
<DT><CODE>quoted-insert (C-q or C-v)</CODE>
<DD><A NAME="IDX108"></A>
Add the next character typed to the line verbatim.  This is
how to insert key sequences like <KBD>C-q</KBD>, for example.
<P>

<A NAME="IDX109"></A>
<DT><CODE>tab-insert (M-<KBD>TAB</KBD>)</CODE>
<DD><A NAME="IDX110"></A>
Insert a tab character.
<P>

<A NAME="IDX111"></A>
<DT><CODE>self-insert (a, b, A, 1, !, <small>...</small>)</CODE>
<DD><A NAME="IDX112"></A>
Insert yourself.
<P>

<A NAME="IDX113"></A>
<DT><CODE>bracketed-paste-begin ()</CODE>
<DD><A NAME="IDX114"></A>
This function is intended to be bound to the "bracketed paste" escape
sequence sent by some terminals, and such a binding is assigned by default.
It allows Readline to insert the pasted text as a single unit without treating
each character as if it had been read from the keyboard.  The characters
are inserted as if each one was bound to <CODE>self-insert</CODE> instead of
executing any editing commands.
<P>

Bracketed paste sets the region (the characters between point and the mark)
to the inserted text. It uses the concept of an <EM>active mark</EM>: when the
mark is active, Readline redisplay uses the terminal's standout mode to
denote the region.
</P><P>

<A NAME="IDX115"></A>
<DT><CODE>transpose-chars (C-t)</CODE>
<DD><A NAME="IDX116"></A>
Drag the character before the cursor forward over
the character at the cursor, moving the
cursor forward as well.  If the insertion point
is at the end of the line, then this
transposes the last two characters of the line.
Negative arguments have no effect.
<P>

<A NAME="IDX117"></A>
<DT><CODE>transpose-words (M-t)</CODE>
<DD><A NAME="IDX118"></A>
Drag the word before point past the word after point,
moving point past that word as well.
If the insertion point is at the end of the line, this transposes
the last two words on the line.
<P>

<A NAME="IDX119"></A>
<DT><CODE>upcase-word (M-u)</CODE>
<DD><A NAME="IDX120"></A>
Uppercase the current (or following) word.  With a negative argument,
uppercase the previous word, but do not move the cursor.
<P>

<A NAME="IDX121"></A>
<DT><CODE>downcase-word (M-l)</CODE>
<DD><A NAME="IDX122"></A>
Lowercase the current (or following) word.  With a negative argument,
lowercase the previous word, but do not move the cursor.
<P>

<A NAME="IDX123"></A>
<DT><CODE>capitalize-word (M-c)</CODE>
<DD><A NAME="IDX124"></A>
Capitalize the current (or following) word.  With a negative argument,
capitalize the previous word, but do not move the cursor.
<P>

<A NAME="IDX125"></A>
<DT><CODE>overwrite-mode ()</CODE>
<DD><A NAME="IDX126"></A>
Toggle overwrite mode.  With an explicit positive numeric argument,
switches to overwrite mode.  With an explicit non-positive numeric
argument, switches to insert mode.  This command affects only
<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
Each call to <CODE>readline()</CODE> starts in insert mode.
<P>

In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
the text at point rather than pushing the text to the right.
Characters bound to <CODE>backward-delete-char</CODE> replace the character
before point with a space.

By default, this command is unbound.

<DT><CODE>digit-argument (<KBD>M-0</KBD>, <KBD>M-1</KBD>, <small>...</small> <KBD>M--</KBD>)</CODE>
<DD><A NAME="IDX160"></A>
Add this digit to the argument already accumulating, or start a new
argument.  <KBD>M--</KBD> starts a negative argument.
<P>

<A NAME="IDX161"></A>
<DT><CODE>universal-argument ()</CODE>
<DD><A NAME="IDX162"></A>
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</CODE>
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 nor 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.

The default is filename completion.
<P>

<A NAME="IDX165"></A>
<DT><CODE>possible-completions (M-?)</CODE>
<DD><A NAME="IDX166"></A>
List the possible completions of the text before point.
When displaying completions, Readline sets the number of columns used
for display to the value of <CODE>completion-display-width</CODE>, the value of
the environment variable <CODE>COLUMNS</CODE>, or the screen width, in that order.
<P>

<A NAME="IDX167"></A>

<A NAME="IDX169"></A>
<DT><CODE>menu-complete ()</CODE>
<DD><A NAME="IDX170"></A>
Similar to <CODE>complete</CODE>, but replaces the word to be completed
with a single match from the list of possible completions.
Repeated execution of <CODE>menu-complete</CODE> steps through the list
of possible completions, inserting each match in turn.
At the end of the list of completions, the bell is rung
(subject to the setting of <CODE>bell-style</CODE>)
and the original text is restored.
An argument of <VAR>n</VAR> moves <VAR>n</VAR> positions forward in the list
of matches; a negative argument may be used to move backward
through the list.
This command is intended to be bound to <KBD>TAB</KBD>, but is unbound
by default.

<H2> 1.5 Readline vi Mode </H2>
<!--docid::SEC22::-->
<P>

While the Readline library does not have a full set of <CODE>vi</CODE>
editing functions, it does contain enough to allow simple editing
of the line.  The Readline <CODE>vi</CODE> mode behaves as specified in
the POSIX standard.
</P><P>

In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
The Readline default is <CODE>emacs</CODE> mode.
</P><P>

When you enter a line in <CODE>vi</CODE> mode, you are already placed in
`insertion' mode, as if you had typed an <SAMP>`i'</SAMP>.  Pressing <KBD>ESC</KBD>
switches you into `command' mode, where you can edit the text of the
line with the standard <CODE>vi</CODE> movement keys, move to previous
history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and
so forth.

in the consistency of user interface across discrete programs that need

<H2> 2.1 Basic Behavior </H2>
<!--docid::SEC24::-->
<P>

Many programs provide a command line interface, such as <CODE>mail</CODE>,
<CODE>ftp</CODE>, and <CODE>sh</CODE>.  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()</CODE> or <CODE>fgets()</CODE>.
</P><P>

<A NAME="IDX219"></A>
<A NAME="IDX220"></A>
</P><P>

The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
and then reads and returns a single line of text from the user.
If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
the caller should <CODE>free()</CODE> the line when it has finished with it.
The declaration for <CODE>readline</CODE> in ANSI C is
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
</pre></td></tr></table></P><P>

So, one might say
<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
</pre></td></tr></table>in order to read a line of text from the user.
The line returned has the final newline removed, so only the
text remains.
</P><P>

If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
Otherwise, the line is ended just as if a newline had been typed.
</P><P>

Readline performs some expansion on the <VAR>prompt</VAR> before it is
displayed on the screen.  See the description of <CODE>rl_expand_prompt</CODE>
(see section <A HREF="readline.html#SEC35">2.4.6 Redisplay</A>) for additional details, especially if <VAR>prompt</VAR>
will contain characters that do not consume physical screen space when
displayed.
</P><P>

If you want the user to be able to get at the line later, (with
<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
line away in a <EM>history</EM> list of such lines.
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;
</pre></td></tr></table></P><P>

For full details on the GNU History Library, see the associated manual.
</P><P>

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()</CODE> library
function, and has the advantage of no static buffer to overflow:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>/* 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 &#38;&#38; *line_read)
    add_history (line_read);

  return (line_read);
}
</pre></td></tr></table></P><P>

This function gives the user the default behaviour of <KBD>TAB</KBD>
completion: completion on file names.  If you do not want Readline to
complete on filenames, you can change the binding of the <KBD>TAB</KBD> key
with <CODE>rl_bind_key()</CODE>.
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int rl_bind_key (int <VAR>key</VAR>, rl_command_func_t *<VAR>function</VAR>);</CODE>
</pre></td></tr></table></P><P>

<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
you want to bind, and <VAR>function</VAR> is the address of the function to
call when <VAR>key</VAR> is pressed.  Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
makes <KBD>TAB</KBD> insert itself.
<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
ASCII character code (between 0 and 255).
</P><P>

Thus, to disable the default <KBD>TAB</KBD> behavior, the following suffices:
<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>rl_bind_key ('\t', rl_insert);</CODE>
</pre></td></tr></table></P><P>

This code should be executed once at the start of your program; you
might write a function called <CODE>initialize_readline()</CODE> which
performs this and other desired initializations, such as installing
custom completers (see section <A HREF="readline.html#SEC45">2.6 Custom Completers</A>).

<H2> 2.2 Custom Functions </H2>
<!--docid::SEC25::-->
<P>

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.
</P><P>

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>&#60;readline/readline.h&#62;</CODE>
in any file that uses Readline's features.  Since some of the definitions
in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
</P><P>

<CODE>readline.h</CODE> defines a C preprocessor variable that should
be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, 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>.  <VAR>MM</VAR> is the two-digit major
version number; <VAR>mm</VAR> is the two-digit minor version number. 
For Readline 4.2, for example, the value of
<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

<H3> 2.2.2 Writing a New Function </H3>
<!--docid::SEC27::-->
<P>

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.
</P><P>

The calling sequence for a command <CODE>foo</CODE> looks like
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>
</pre></td></tr></table></P><P>

where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
<VAR>key</VAR> is the key that invoked this function.
</P><P>

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.
</P><P>

A command function should return 0 if its action completes successfully,
and a value greater than zero if some error occurs.
This is the convention obeyed by all of the builtin Readline bindable
command functions.

Readline do it the first time <CODE>readline()</CODE> is called, it should set
this variable to a non-zero value after displaying the prompt.
The prompt must also be passed as the argument to <CODE>readline()</CODE> so

<A NAME="IDX244"></A>
<DL>
<DT><U>Variable:</U> rl_hook_func_t * <B>rl_event_hook</B>

when Readline is waiting for terminal input.
By default, this will be called at most ten times a second if there
is no keyboard input.

<A NAME="IDX245"></A>
<DL>
<DT><U>Variable:</U> rl_getc_func_t * <B>rl_getc_function</B>
<DD>If non-zero, Readline will call indirectly through this pointer
to get a character from the input stream.  By default, it is set to
<CODE>rl_getc</CODE>, the default Readline character input function
(see section <A HREF="readline.html#SEC37">2.4.8 Character Input</A>).
In general, an application that sets <VAR>rl_getc_function</VAR> should consider
setting <VAR>rl_input_available_hook</VAR> as well.
</DL>

<A NAME="IDX246"></A>
<DL>
<DT><U>Variable:</U> rl_hook_func_t * <B>rl_signal_event_hook</B>

call is interrupted when Readline is reading terminal input.
</DL>
</P><P>

<A NAME="IDX247"></A>
<DL>
<DT><U>Variable:</U> rl_hook_func_t * <B>rl_input_available_hook</B>
<DD>If non-zero, Readline will use this function's return value when it needs
to determine whether or not there is available input on the current input
source.
The default hook checks <CODE>rl_instream</CODE>; if an application is using a
different input source, it should set the hook appropriately.
Readline queries for available input when implementing intra-key-sequence
timeouts during input and incremental searches.
This may use an application-specific timeout before returning a value;
Readline uses the value passed to <CODE>rl_set_keyboard_input_timeout()</CODE>
or the value of the user-settable <VAR>keyseq-timeout</VAR> variable.
This is designed for use by applications using Readline's callback interface
(see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), which may not use the traditional
<CODE>read(2)</CODE> and file descriptor interface, or other applications using
a different input mechanism.
If an application uses an input mechanism or hook that can potentially exceed
the value of <VAR>keyseq-timeout</VAR>, it should increase the timeout or set
this hook appropriately even when not using the callback interface.
In general, an application that sets <VAR>rl_getc_function</VAR> should consider
setting <VAR>rl_input_available_hook</VAR> as well.

<H3> 2.4.1 Naming a Function </H3>
<!--docid::SEC30::-->
<P>

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
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>Meta-Rubout:	backward-kill-word
</pre></td></tr></table></P><P>

This binds the keystroke <KBD>Meta-Rubout</KBD> to the function
<EM>descriptively</EM> named <CODE>backward-kill-word</CODE>.  You, as the
programmer, should bind the functions you write to descriptive names as
well.  Readline provides a function for doing that:
</P><P>

<A NAME="IDX261"></A>
<DL>
<DT><U>Function:</U> int <B>rl_add_defun</B> <I>(const char *name, rl_command_func_t *function, int key)</I>
<DD>Add <VAR>name</VAR> to the list of named functions.  Make <VAR>function</VAR> be
the function that gets called.  If <VAR>key</VAR> is not -1, then bind it to
<VAR>function</VAR> using <CODE>rl_bind_key()</CODE>.
</DL>
</P><P>

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.

<P>

Key bindings take place on a <EM>keymap</EM>.  The keymap is the
association between the keys that the user types and the functions that

<A NAME="IDX272"></A>
<DL>
<DT><U>Function:</U> int <B>rl_set_keymap_name</B> <I>(const char *name, Keymap keymap)</I>
<DD>Set the name of <VAR>keymap</VAR>.  This name will then be "registered" and
available for use in a <CODE>set keymap</CODE> inputrc directive
see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
The <VAR>name</VAR> may not be one of Readline's builtin keymap names;
you may not add a different name for one of Readline's builtin keymaps.
You may replace the name associated with a given keymap by calling this
function more than once with the same <VAR>keymap</VAR> argument.
You may associate a registered <VAR>name</VAR> with a new keymap by calling this
function more than once  with the same <VAR>name</VAR> argument.
There is no way to remove a named keymap once the name has been
registered.
Readline will make a copy of <VAR>name</VAR>.
The return value is greater than zero unless <VAR>name</VAR> is one of
Readline's builtin keymap names or <VAR>keymap</VAR> is one of Readline's
builtin keymaps.

<H3> 2.4.3 Binding Keys </H3>
<!--docid::SEC32::-->
<P>

Key sequences are associate with functions through the keymap.
Readline has several internal keymaps: <CODE>emacs_standard_keymap</CODE>,
<CODE>emacs_meta_keymap</CODE>, <CODE>emacs_ctlx_keymap</CODE>,
<CODE>vi_movement_keymap</CODE>, and <CODE>vi_insertion_keymap</CODE>.
<CODE>emacs_standard_keymap</CODE> is the default, and the examples in
this manual assume that.
</P><P>

Since <CODE>readline()</CODE> 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()</CODE> will be overridden.
An alternate mechanism is to install custom key bindings in an
initialization function assigned to the <CODE>rl_startup_hook</CODE> variable
(see section <A HREF="readline.html#SEC28">2.3 Readline Variables</A>).
</P><P>

These functions manage key bindings.

<H3> 2.4.5 Allowing Undoing </H3>
<!--docid::SEC34::-->
<P>

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.
</P><P>

If your function simply inserts text once, or deletes text once, and
uses <CODE>rl_insert_text()</CODE> or <CODE>rl_delete_text()</CODE> to do it, then
undoing is already done for you automatically.
</P><P>

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()</CODE> and
<CODE>rl_end_undo_group()</CODE>.
</P><P>

The types of events that can be undone are:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END }; 
</FONT></pre></td></tr></table></P><P>

Notice that <CODE>UNDO_DELETE</CODE> means to insert some text, and
<CODE>UNDO_INSERT</CODE> means to delete some text.  That is, the undo code
tells what to undo, not how to undo it.  <CODE>UNDO_BEGIN</CODE> and
<CODE>UNDO_END</CODE> are tags added by <CODE>rl_begin_undo_group()</CODE> and
<CODE>rl_end_undo_group()</CODE>.
</P><P>

<A NAME="IDX298"></A>
<DL>
<DT><U>Function:</U> int <B>rl_begin_undo_group</B> <I>(void)</I>
<DD>Begins saving undo information in a group construct.  The undo
information usually comes from calls to <CODE>rl_insert_text()</CODE> and
<CODE>rl_delete_text()</CODE>, but could be the result of calls to
<CODE>rl_add_undo()</CODE>.

()</CODE>.  There should be one call to <CODE>rl_end_undo_group()</CODE>
for each call to <CODE>rl_begin_undo_group()</CODE>.
</DL>
</P><P>

<A NAME="IDX300"></A>
<DL>
<DT><U>Function:</U> void <B>rl_add_undo</B> <I>(enum undo_code what, int start, int end, char *text)</I>
<DD>Remember how to undo an event (according to <VAR>what</VAR>).  The affected
text runs from <VAR>start</VAR> to <VAR>end</VAR>, and encompasses <VAR>text</VAR>.
</DL>
</P><P>

<A NAME="IDX301"></A>
<DL>
<DT><U>Function:</U> void <B>rl_free_undo_list</B> <I>(void)</I>

<DD>Undo the first thing on the undo list.  Returns <CODE>0</CODE> if there was
nothing to undo, non-zero if something was undone.
</DL>
</P><P>

Finally, if you neither insert nor delete text, but directly modify the
existing text (e.g., change its case), call <CODE>rl_modifying()</CODE>
once, just before you modify the text.  You must supply the indices of
the text range that you are going to modify.
</P><P>

<A NAME="IDX303"></A>
<DL>
<DT><U>Function:</U> int <B>rl_modifying</B> <I>(int start, int end)</I>
<DD>Tell Readline to save the text between <VAR>start</VAR> and <VAR>end</VAR> as a
single undo unit.  It is assumed that you will subsequently modify
that text.

<H3> 2.4.12 Alternate Interface </H3>
<!--docid::SEC41::-->
<P>

An alternate interface is available to plain <CODE>readline()</CODE>.  Some
applications need to interleave keyboard I/O with file, device, or
window system I/O, typically by using a main loop to <CODE>select()</CODE>
on various file descriptors.  To accommodate this need, readline can
also be invoked as a `callback' function from an event loop.  There
are functions available to make this easy.
</P><P>

<A NAME="IDX362"></A>
<DL>
<DT><U>Function:</U> void <B>rl_callback_handler_install</B> <I>(const char *prompt, rl_vcpfunc_t *lhandler)</I>
<DD>Set up the terminal for readline I/O and display the initial
expanded value of <VAR>prompt</VAR>.  Save the value of <VAR>lhandler</VAR> to
use as a handler function to call when a complete line of input has been
entered.
The handler function receives the text of the line as an argument.
As with <CODE>readline()</CODE>, the handler function should <CODE>free</CODE> the
line when it it finished with it.
</DL>
</P><P>

<A NAME="IDX363"></A>
<DL>
<DT><U>Function:</U> void <B>rl_callback_read_char</B> <I>(void)</I>
<DD>Whenever an application determines that keyboard input is available, it
should call <CODE>rl_callback_read_char()</CODE>, which will read the next
character from the current input source.
If that character completes the line, <CODE>rl_callback_read_char</CODE> will
invoke the <VAR>lhandler</VAR> function installed by
<CODE>rl_callback_handler_install</CODE> to process the line.
Before calling the <VAR>lhandler</VAR> function, the terminal settings are
reset to the values they had before calling
<CODE>rl_callback_handler_install</CODE>.
If the <VAR>lhandler</VAR> function returns,
and the line handler remains installed,
the terminal settings are modified for Readline's use again.
<CODE>EOF</CODE> is indicated by calling <VAR>lhandler</VAR> with a
<CODE>NULL</CODE> line.
</DL>
</P><P>

<A NAME="IDX364"></A>
<DL>
<DT><U>Function:</U> void <B>rl_callback_sigcleanup</B> <I>(void)</I>
<DD>Clean up any internal state the callback interface uses to maintain state
between calls to rl_callback_read_char (e.g., the state of any active
incremental searches).  This is intended to be used by applications that
wish to perform their own signal handling; Readline's internal signal handler
calls this when appropriate.
</DL>
</P><P>

<A NAME="IDX365"></A>
<DL>
<DT><U>Function:</U> void <B>rl_callback_handler_remove</B> <I>(void)</I>
<DD>Restore the terminal to its initial state and remove the line handler.
You may call this function from within a callback as well as independently.
If the <VAR>lhandler</VAR> installed by <CODE>rl_callback_handler_install</CODE>
does not exit the program, either this function or the function referred
to by the value of <CODE>rl_deprep_term_function</CODE> should be called before
the program exits to reset the terminal settings.

<H2> 2.5 Readline Signal Handling </H2>
<!--docid::SEC44::-->
<P>

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. 
</P><P>

Readline contains an internal signal handler that is installed for a
number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
<CODE>SIGHUP</CODE>, 
<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
When one of these signals is received, the signal handler
will reset the terminal attributes to those that were in effect before
<CODE>readline()</CODE> was called, reset the signal handling to what it was
before <CODE>readline()</CODE> 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</CODE> 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()</CODE> below).
</P><P>

There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
the kernel sends to a process whenever the terminal's size changes (for
example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
handler updates Readline's internal screen size information, and then calls
any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
Readline calls the application's <CODE>SIGWINCH</CODE> 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</CODE> back to a main processing loop), it <EM>must</EM>
call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
terminal state.
</P><P>

When an application is using the callback interface
(see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), Readline installs signal handlers only for
the duration of the call to <CODE>rl_callback_read_char</CODE>.  Applications
using the callback interface should be prepared to clean up Readline's
state if they wish to handle the signal before the line handler completes
and restores the terminal state.
</P><P>

If an application using the callback interface wishes to have Readline
install its signal handlers at the time the application calls
<CODE>rl_callback_handler_install</CODE> and remove them only when a complete
line of input has been read, it should set the
<CODE>rl_persistent_signal_handlers</CODE> variable to a non-zero value.
This allows an application to defer all of the handling of the signals
Readline catches to Readline.
Applications should use this variable with care; it can result in Readline
catching signals and not acting on them (or allowing the application to react
to them) until the application calls <CODE>rl_callback_read_char</CODE>.  This
can result in an application becoming less responsive to keyboard signals
like SIGINT.
If an application does not want or need to perform any signal handling, or
does not need to do any processing between calls to <CODE>rl_callback_read_char</CODE>,
setting this variable may be desirable.
</P><P>

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()</CODE>, not in
a signal handler, so Readline's internal signal state is not corrupted.

<H2> 2.6 Custom Completers </H2>
<!--docid::SEC45::-->
<P>

Typically, a program that reads commands from the user has a way of
disambiguating commands and data.  If your program is one of these, then
it can provide completion for commands, data, or both.
The following sections describe how your program and Readline
cooperate to provide this service.

<H3> 2.6.1 How Completing Works </H3>
<!--docid::SEC46::-->
<P>

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.
</P><P>

There are three major functions used to perform completion:
</P><P>

<OL>
<LI>
The user-interface function <CODE>rl_complete()</CODE>.  This function is
called with the same arguments as other bindable Readline functions:
<VAR>count</VAR> and <VAR>invoking_key</VAR>.
It isolates the word to be completed and calls
<CODE>rl_completion_matches()</CODE> 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.
<P>

<LI>
The internal function <CODE>rl_completion_matches()</CODE> uses an
application-supplied <EM>generator</EM> 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</CODE>.
<P>

<LI>
The generator function is called repeatedly from
<CODE>rl_completion_matches()</CODE>, returning a string each time.  The
arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> 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</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
no more possibilities left.  Usually the generator function computes the
list of possible completions when <VAR>state</VAR> 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()</CODE>; Readline
frees the strings when it has finished with them.
Such a generator function is referred to as an
<EM>application-specific completion function</EM>.

<DD>Complete the word at or before point.  <VAR>what_to_do</VAR> says what to do
with the completion.  A value of <SAMP>`?'</SAMP> means list the possible
completions.  <SAMP>`TAB'</SAMP> means do standard completion.  <SAMP>`*'</SAMP> means
insert all of the possible completions.  <SAMP>`!'</SAMP> means to display
all of the possible completions, if there is more than one, as well as
performing partial completion.  <SAMP>`@'</SAMP> is similar to <SAMP>`!'</SAMP>, but
possible completions are not listed if the possible completions share
a common prefix.

<A NAME="IDX392"></A>
<DL>
<DT><U>Variable:</U> rl_compentry_func_t * <B>rl_completion_entry_function</B>
<DD>A pointer to the generator function for <CODE>rl_completion_matches()</CODE>.
<CODE>NULL</CODE> means to use <CODE>rl_filename_completion_function()</CODE>,
the default filename completer.
</DL>
</P><P>

<A NAME="IDX393"></A>
<DL>
<DT><U>Variable:</U> rl_completion_func_t * <B>rl_attempted_completion_function</B>
<DD>A pointer to an alternative function to create matches.
The function is called with <VAR>text</VAR>, <VAR>start</VAR>, and <VAR>end</VAR>.
<VAR>start</VAR> and <VAR>end</VAR> are indices in <CODE>rl_line_buffer</CODE> defining
the boundaries of <VAR>text</VAR>, which is a character string.
If this function exists and returns <CODE>NULL</CODE>, or if this variable is
set to <CODE>NULL</CODE>, then <CODE>rl_complete()</CODE> will call the value of
<CODE>rl_completion_entry_function</CODE> to generate matches, otherwise the
array of strings returned will be used.
If this function sets the <CODE>rl_attempted_completion_over</CODE>
variable to a non-zero value, Readline will not perform its default
completion even if this function returns no matches.
</DL>
</P><P>

<A NAME="IDX394"></A>
<DL>
<DT><U>Variable:</U> rl_quote_func_t * <B>rl_filename_quoting_function</B>
<DD>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</CODE>
appears in a completed filename.  The function is called with
<VAR>text</VAR>, <VAR>match_type</VAR>, and <VAR>quote_pointer</VAR>.  The <VAR>text</VAR>
is the filename to be quoted.  The <VAR>match_type</VAR> is either
<CODE>SINGLE_MATCH</CODE>, if there is only one completion match, or
<CODE>MULT_MATCH</CODE>.  Some functions use this to decide whether or not to
insert a closing quote character.  The <VAR>quote_pointer</VAR> is a pointer
to any opening quote character the user typed.  Some functions choose
to reset this character.
</DL>
</P><P>

<A NAME="IDX395"></A>
<DL>
<DT><U>Variable:</U> rl_dequote_func_t * <B>rl_filename_dequoting_function</B>
<DD>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</VAR>, the text of the word
to be dequoted, and <VAR>quote_char</VAR>, which is the quoting character 
that delimits the filename (usually <SAMP>`''</SAMP> or <SAMP>`"'</SAMP>).  If
<VAR>quote_char</VAR> is zero, the filename was not in an embedded string.
</DL>
</P><P>

<A NAME="IDX396"></A>
<DL>
<DT><U>Variable:</U> rl_linebuf_func_t * <B>rl_char_is_quoted_p</B>
<DD>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</VAR>, the text of the line, and <VAR>index</VAR>, the
index of the character in the line.  It is used to decide whether a
character found in <CODE>rl_completer_word_break_characters</CODE> should be
used to break words for the completer.
</DL>
</P><P>

<A NAME="IDX397"></A>
<DL>
<DT><U>Variable:</U> rl_compignore_func_t * <B>rl_ignore_some_completions_function</B>
<DD>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</CODE> terminated array of matches.
The first element (<CODE>matches[0]</CODE>) 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.
</DL>
</P><P>

<A NAME="IDX398"></A>
<DL>
<DT><U>Variable:</U> rl_icppfunc_t * <B>rl_directory_completion_hook</B>
<DD>This function, if defined, is allowed to modify the directory portion
of filenames Readline completes.
It could be used to expand symbolic links or shell variables in pathnames.
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 used as part of the completion, replacing
the directory portion of the pathname the user typed.
At the least, even if no other expansion is performed, this function should
remove any quote characters from the directory name, because its result will
be passed directly to <CODE>opendir()</CODE>.
</P><P>

The directory completion hook returns an integer that should be non-zero if
the function modifies its directory argument.
The function should not modify the directory argument if it returns 0.
</DL>
</P><P>

<A NAME="IDX399"></A>
<DL>
<DT><U>Variable:</U> rl_icppfunc_t * <B>rl_directory_rewrite_hook;</B>
<DD>If non-zero, this is the address of a function to call when completing
a directory name.  This function takes the address of the directory name
to be modified as an argument.  Unlike <CODE>rl_directory_completion_hook</CODE>,
it only modifies the directory name used in <CODE>opendir</CODE>, not what is
displayed when the possible completions are printed or inserted.  It is
called before rl_directory_completion_hook.
At the least, even if no other expansion is performed, this function should
remove any quote characters from the directory name, because its result will
be passed directly to <CODE>opendir()</CODE>.
</P><P>

The directory rewrite hook returns an integer that should be non-zero if
the function modifies its directory argument.
The function should not modify the directory argument if it returns 0.
</DL>
</P><P>

<A NAME="IDX400"></A>
<DL>
<DT><U>Variable:</U> rl_icppfunc_t * <B>rl_filename_stat_hook</B>
<DD>If non-zero, this is the address of a function for the completer to
call before deciding which character to append to a completed name.
This function modifies its filename name argument, and the modified value
is passed to <CODE>stat()</CODE> to determine the file's type and characteristics.
This function does not need to remove quote characters from the filename.
</P><P>

The stat hook returns an integer that should be non-zero if
the function modifies its directory argument.
The function should not modify the directory argument if it returns 0.
</DL>
</P><P>

<A NAME="IDX401"></A>
<DL>
<DT><U>Variable:</U> rl_dequote_func_t * <B>rl_filename_rewrite_hook</B>
<DD>If non-zero, this is the address of a function called when reading
directory entries from the filesystem for completion and comparing
them to the partial word to be completed.  The function should
perform any necessary application or system-specific conversion on
the filename, such as converting between character sets or converting
from a filesystem format to a character input format.
The function takes two arguments: <VAR>fname</VAR>, the filename to be converted,
and <VAR>fnlen</VAR>, its length in bytes.
It must either return its first argument (if no conversion takes place)
or the converted filename in newly-allocated memory.  The converted
form is used to compare against the word to be completed, and, if it
matches, is added to the list of matches.  Readline will free the
allocated string.
</DL>
</P><P>

<A NAME="IDX402"></A>
<DL>
<DT><U>Variable:</U> rl_compdisp_func_t * <B>rl_completion_display_matches_hook</B>
<DD>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 **</CODE><VAR>matches</VAR>, <CODE>int</CODE> <VAR>num_matches</VAR>, <CODE>int</CODE> <VAR>max_length</VAR>)
where <VAR>matches</VAR> is the array of matching strings,
<VAR>num_matches</VAR> is the number of strings in that array, and
<VAR>max_length</VAR> is the length of the longest string in that array.
Readline provides a convenience function, <CODE>rl_display_match_list</CODE>,
that takes care of doing the display to Readline's output stream.
You may call that function from this hook.
</DL>

<A NAME="IDX403"></A>
<DL>
<DT><U>Variable:</U> const char * <B>rl_basic_word_break_characters</B>
<DD>The basic list of characters that signal a break between words for the

<CODE>rl_basic_word_break_characters</CODE>.
</DL>
</P><P>

<A NAME="IDX406"></A>
<DL>
<DT><U>Variable:</U> rl_cpvfunc_t * <B>rl_completion_word_break_hook</B>
<DD>If non-zero, this is the address of a function to call when Readline is
deciding where to separate words for word completion.  It should return
a character string like <CODE>rl_completer_word_break_characters</CODE> to be
used to perform the current completion.  The function may choose to set
<CODE>rl_completer_word_break_characters</CODE> itself.  If the function
returns <CODE>NULL</CODE>, <CODE>rl_completer_word_break_characters</CODE> is used.
</DL>
</P><P>

<A NAME="IDX407"></A>
<DL>
<DT><U>Variable:</U> const char * <B>rl_completer_quote_characters</B>
<DD>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</CODE> are treated as any other character,
unless they also appear within this list.
</DL>
</P><P>

<A NAME="IDX408"></A>
<DL>
<DT><U>Variable:</U> const char * <B>rl_filename_quote_characters</B>

<DT><U>Variable:</U> const char * <B>rl_special_prefixes</B>
<DD>The list of characters that are word break characters, but should be
left in <VAR>text</VAR> 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.

<A NAME="IDX410"></A>
<DL>
<DT><U>Variable:</U> int <B>rl_completion_query_items</B>
<DD>Up to this many items will be displayed in response to a
possible-completions call.  After that, readline asks the user if she is sure
she wants to see them all.  The default value is 100.  A negative value 
indicates that Readline should never ask the user.

line, this character is appended to the inserted completion text.  The
default is a space character (<SAMP>` '</SAMP>).  Setting this to the null
character (<SAMP>`\0'</SAMP>) prevents anything being appended automatically.
This can be changed in application-specific completion functions to
provide the "most sensible word separator character" according to
an application-specific command line syntax specification.
It is set to the default before any application-specific completion function
is called, and may only be changed within such a function.

<DD>If non-zero, a slash will be appended to completed filenames that are
symbolic links to directory names, subject to the value of the

This variable exists so that application-specific completion functions
can override the user's global preference (set via the
<VAR>mark-symlinked-directories</VAR> Readline variable) if appropriate.
This variable is set to the user's preference before any
application-specific completion function is called, so unless that

<DD>Non-zero means that the results of the matches are to be treated as
filenames.  This is <EM>always</EM> zero when completion is attempted,
and can only be changed
within an application-specific completion function.  If it is set to a
non-zero value by such a function, directory names have a slash appended

when completion is attempted, and can only be changed within an
application-specific completion function.

if the application's completion function returns no matches.

refers to any such manual or work.  Any member of the public is a
licensee, and is addressed as "you".  You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
</P><P>

A "Modified Version" of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
</P><P>

A "Secondary Section" is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall
subject (or to related matters) and contains nothing that could fall
directly within that overall subject.  (Thus, if the Document is in
part a textbook of mathematics, a Secondary Section may not explain
any mathematics.)  The relationship could be a matter of historical
connection with the subject or with related matters, or of legal,
commercial, philosophical, ethical or political position regarding
them.
</P><P>

The "Invariant Sections" are certain Secondary Sections whose titles
are designated, as being those of Invariant Sections, in the notice
that says that the Document is released under this License.  If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant.  The Document may contain zero
Invariant Sections.  If the Document does not identify any Invariant
Sections then there are none.
</P><P>

The "Cover Texts" are certain short passages of text that are listed,
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
the Document is released under this License.  A Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
</P><P>

A "Transparent" copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or
for automatic translation to a variety of formats suitable for input
to text formatters.  A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text.  A copy that is not "Transparent" is called "Opaque".
</P><P>

Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, LaTeX input
format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
<FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification.  Examples
of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
<FONT SIZE="-1">JPG</FONT>.  Opaque formats include proprietary formats that can be
read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
<FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
output purposes only.
</P><P>

The "Title Page" means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page.  For works in
formats which do not have any title page as such, "Title Page" means
the text near the most prominent appearance of the work's title,
preceding the beginning of the body of the text.
</P><P>

The "publisher" means any person or entity that distributes copies
of the Document to the public.
</P><P>

A section "Entitled XYZ" means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language.  (Here XYZ stands for a
specific section name mentioned below, such as "Acknowledgements",
"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
of such a section when you modify the Document means that it remains a
section "Entitled XYZ" according to this definition.
</P><P>

The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document.  These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
</P><P>

<LI>
VERBATIM COPYING
<P>

You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies
to the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License.  You may not use
technical measures to obstruct or control the reading or further
copying of the copies you make or distribute.  However, you may accept
compensation in exchange for copies.  If you distribute a large enough
number of copies you must also follow the conditions in section 3.
</P><P>

You may also lend copies, under the same conditions stated above, and
you may publicly display copies.
</P><P>

<LI>
COPYING IN QUANTITY
<P>

If you publish printed copies (or copies in media that commonly have
printed covers) of the Document, numbering more than 100, and the
Document's license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
the back cover.  Both covers must also clearly and legibly identify
you as the publisher of these copies.  The front cover must present
the full title with all words of the title equally prominent and
visible.  You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve
the title of the Document and satisfy these conditions, can be treated
as verbatim copying in other respects.
</P><P>

If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.
</P><P>

If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps,
when you begin distribution of Opaque copies in quantity, to ensure
that this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you distribute an
Opaque copy (directly or through your agents or retailers) of that
edition to the public.
</P><P>

It is requested, but not required, that you contact the authors of the
Document well before redistributing any large number of copies, to give
them a chance to provide you with an updated version of the Document.
</P><P>

<LI>
MODIFICATIONS
<P>

You may copy and distribute a Modified Version of the Document under
the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution
and modification of the Modified Version to whoever possesses a copy
of it.  In addition, you must do these things in the Modified Version:
</P><P>

<OL>
<LI>
Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document).  You may use the same title as a previous version
if the original publisher of that version gives permission.
<P>

<LI>
List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
<P>

<LI>
State on the Title page the name of the publisher of the
Modified Version, as the publisher.
<P>

<LI>
Preserve all the copyright notices of the Document.
<P>

<LI>
Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
<P>

<LI>
Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
<P>

<LI>
Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
<P>

<LI>
Include an unaltered copy of this License.
<P>

<LI>
Preserve the section Entitled "History", Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page.  If
there is no section Entitled "History" in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
<P>

<LI>
Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on.  These may be placed in the "History" section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
<P>

<LI>
For any section Entitled "Acknowledgements" or "Dedications", Preserve
the Title of the section, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.
<P>

<LI>
Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles.  Section numbers
or the equivalent are not considered part of the section titles.
<P>

<LI>
Delete any section Entitled "Endorsements".  Such a section
may not be included in the Modified Version.
<P>

<LI>
Do not retitle any existing section to be Entitled "Endorsements" or
to conflict in title with any Invariant Section.
<P>

<LI>
Preserve any Warranty Disclaimers.
</OL>
<P>

If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant.  To do this, add their titles to the
list of Invariant Sections in the Modified Version's license notice.
These titles must be distinct from any other section titles.
</P><P>

You may add a section Entitled "Endorsements", provided it contains
nothing but endorsements of your Modified Version by various
parties--for example, statements of peer review or that the text has
been approved by an organization as the authoritative definition of a
standard.
</P><P>

You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version.  Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity.  If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
</P><P>

The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
</P><P>

<LI>
COMBINING DOCUMENTS
<P>

You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
</P><P>

The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy.  If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
</P><P>

In the combination, you must combine any sections Entitled "History"
in the various original documents, forming one section Entitled
"History"; likewise combine any sections Entitled "Acknowledgements",
and any sections Entitled "Dedications".  You must delete all
sections Entitled "Endorsements."
</P><P>

<LI>
COLLECTIONS OF DOCUMENTS
<P>

You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
</P><P>

You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
</P><P>

<LI>
AGGREGATION WITH INDEPENDENT WORKS
<P>

A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an "aggregate" if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
</P><P>

If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
</P><P>

<LI>
TRANSLATION
<P>

Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections.  You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers.  In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.
</P><P>

If a section in the Document is Entitled "Acknowledgements",
"Dedications", or "History", the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.
</P><P>

<LI>
TERMINATION
<P>

You may not copy, modify, sublicense, or distribute the Document
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense, or distribute it is void, and
will automatically terminate your rights under this License.
</P><P>

However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
</P><P>

Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
</P><P>

Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, receipt of a copy of some or all of the same material does
not give you any rights to use it.
</P><P>

<LI>
FUTURE REVISIONS OF THIS LICENSE
<P>

The Free Software Foundation may publish new, revised versions
of the GNU Free Documentation License from time to time.  Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.  See
<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
</P><P>

Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License "or any later version" applies to it, you have the option of
following the terms and conditions either of that specified version or
of any later version that has been published (not as a draft) by the
Free Software Foundation.  If the Document does not specify a version
number of this License, you may choose any version ever published (not
as a draft) by the Free Software Foundation.  If the Document
specifies that a proxy can decide which future versions of this
License can be used, that proxy's public statement of acceptance of a
version permanently authorizes you to choose that version for the
Document.
</P><P>

<LI>
RELICENSING
<P>

"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
World Wide Web server that publishes copyrightable works and also
provides prominent facilities for anybody to edit those works.  A
public wiki that anybody can edit is an example of such a server.  A
"Massive Multiauthor Collaboration" (or "MMC") contained in the
site means any set of copyrightable works thus published on the MMC
site.
</P><P>

"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
license published by Creative Commons Corporation, a not-for-profit
corporation with a principal place of business in San Francisco,
California, as well as future copyleft versions of that license
published by that same organization.
</P><P>

"Incorporate" means to publish or republish a Document, in whole or
in part, as part of another Document.
</P><P>

An MMC is "eligible for relicensing" if it is licensed under this
License, and if all works that were first published under this License
somewhere other than this MMC, and subsequently incorporated in whole
or in part into the MMC, (1) had no cover texts or invariant sections,
and (2) were thus incorporated prior to November 1, 2008.
</P><P>

The operator of an MMC Site may republish an MMC contained in the site
under CC-BY-SA on the same site at any time before August 1, 2009,
provided the MMC is eligible for relicensing.
</P><P>

<A NAME="SEC51"></A>
<H2> ADDENDUM: How to use this License for your documents </H2>
<!--docid::SEC51::-->
<P>

To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and
license notices just after the title page:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>  Copyright (C)  <VAR>year</VAR>  <VAR>your name</VAR>.
  Permission is granted to copy, distribute and/or modify this document
  under the terms of the GNU Free Documentation License, Version 1.3
  or any later version published by the Free Software Foundation;
  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
  Texts.  A copy of the license is included in the section entitled ``GNU
  Free Documentation License''.
</FONT></pre></td></tr></table></P><P>

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
replace the "with<small>...</small>Texts." line with this:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>    with the Invariant Sections being <VAR>list their titles</VAR>, with
    the Front-Cover Texts being <VAR>list</VAR>, and with the Back-Cover Texts
    being <VAR>list</VAR>.
</FONT></pre></td></tr></table></P><P>

If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.
</P><P>

If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License,
to permit their use in free software.
