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="gdb_28.html#SEC665">27.3 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.

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.

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.

forward a word. It is a loose convention that control keystrokes

operate on characters while meta keystrokes operate on words.

<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.
|

If the description for a command says that it `kills' text, then you can
|
||
|
|
be sure that you can get the text back in a different (or the same)
|
||
|
|
place later.

When you use a kill command, the text is saved in a <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.

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.

<H3> 27.2.5 Searching for Commands in the History </H3>

<!--docid::SEC664::-->

<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.

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>.
|
||
|
|
</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.

<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. The name of the key
|
||
|
|
can be expressed in different ways, depending on what you find most
|
||
|
|
comfortable.

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:

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 extends to the end of the line;
|
||
|
|
no characters are required to isolate it.
|
||
|
|
<P>

||
|
|

<DL COMPACT>
|
||
|
|
<DT><CODE>mode</CODE>
|
||
|
|
<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
|
||
|
|
whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
|
||
|
|
This may be used in conjunction
|
||
|
|
with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
|
||
|
|
the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
|
||
|
|
Readline is starting out in <CODE>emacs</CODE> mode.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
<DT><CODE>term</CODE>
|
||
|
|
<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
|
||
|
|
key bindings, perhaps to bind the key sequences output by the
|
||
|
|
terminal's function keys. The word on the right side of the
|
||
|
|
<SAMP>`='</SAMP> is tested against both the full name of the terminal and
|
||
|
|
the portion of the terminal name before the first <SAMP>`-'</SAMP>. This
|
||
|
|
allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
|
||
|
|
for instance.
|
||
|
|
<P>
|
||
|
|
|
||
|
|
<DT><CODE>application</CODE>
|
||
|
|
<DD>The <VAR>application</VAR> construct is used to include
|
||
|
|
application-specific settings. Each program using the Readline
|
||
|
|
library sets the <VAR>application name</VAR>, and you can test for
|
||
|
|
a particular value.
|
||
|
|
This could be used to bind key sequences to functions useful for
|
||
|
|
a specific program. For instance, the following command adds a
|
||
|
|
key sequence that quotes the current or previous word in Bash:
|
||
|
|
<TABLE><tr><td> </td><td class=example><pre>$if Bash
|
||
|
|
# Quote the current or previous word
|
||
|
|
"\C-xq": "\eb\"\ef\""
|
||
|
|
$endif
|
||
|
|
</pre></td></tr></table></DL>
|
||
|
|
<P>
|
||
|
|
|
||
|
|
<DT><CODE>$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> </td><td class=example><pre>$include /etc/inputrc
|

|

Add this digit to the argument already accumulating, or start a new

argument. <KBD>M--</KBD> starts a negative argument.

|

|
|
This is another way to specify an argument.
|
||
|
|
If this command is followed by one or more digits, optionally with a
|
||
|
|
leading minus sign, those digits define the argument.
|
||
|
|
If the command is followed by digits, executing <CODE>universal-argument</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 or minus sign, the argument count
|
||
|
|
for the next command is multiplied by four.
|
||
|
|
The argument count is initially one, so executing this function the
|
||
|
|
first time makes the argument count four, a second time makes the
|
||
|
|
argument count sixteen, and so on.
|
||
|
|
By default, this is not bound to a key.

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 1003.2 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.
