<p><small>GDB</small> can style its output on a capable terminal. This is
|
|
enabled by default on most systems, but disabled by default when in
|
|
batch mode (see <a href="Mode-Options.html#Mode-Options">Mode Options</a>). Various style settings are available;
|
|
and styles can also be disabled entirely.
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>set style enabled ‘<samp>on|off</samp>’</code></dt>
|
|
<dd><p>Enable or disable all styling. The default is host-dependent, with
|
|
most hosts defaulting to ‘<samp>on</samp>’.
|
|
</p>
|
|
</dd>
|
|
<dt><code>show style enabled</code></dt>
|
|
<dd><p>Show the current state of styling.
|
|
</p>
|
|
</dd>
|
|
<dt><code>set style sources ‘<samp>on|off</samp>’</code></dt>
|
|
<dd><p>Enable or disable source code styling. This affects whether source
|
|
code, such as the output of the <code>list</code> command, is styled. Note
|
|
that source styling only works if styling in general is enabled, and
|
|
if <small>GDB</small> was linked with the GNU Source Highlight library. The
|
|
default is ‘<samp>on</samp>’.
|

</p>

</dl>
|
|
|
|
<p>Subcommands of <code>set style</code> control specific forms of styling.
|
|
These subcommands all follow the same pattern: each style-able object
|
|
can be styled with a foreground color, a background color, and an
|
|
intensity.
|
|
</p>
|
|
<p>For example, the style of file names can be controlled using the
|
|
<code>set style filename</code> group of commands:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>set style filename background <var>color</var></code></dt>
|
|
<dd><p>Set the background to <var>color</var>. Valid colors are ‘<samp>none</samp>’
|
|
(meaning the terminal’s default color), ‘<samp>black</samp>’, ‘<samp>red</samp>’,
|
|
‘<samp>green</samp>’, ‘<samp>yellow</samp>’, ‘<samp>blue</samp>’, ‘<samp>magenta</samp>’, ‘<samp>cyan</samp>’,
|
|
and‘<samp>white</samp>’.
|
|
</p>
|
|
</dd>
|
|
<dt><code>set style filename foreground <var>color</var></code></dt>
|
|
<dd><p>Set the foreground to <var>color</var>. Valid colors are ‘<samp>none</samp>’
|
|
(meaning the terminal’s default color), ‘<samp>black</samp>’, ‘<samp>red</samp>’,
|
|
‘<samp>green</samp>’, ‘<samp>yellow</samp>’, ‘<samp>blue</samp>’, ‘<samp>magenta</samp>’, ‘<samp>cyan</samp>’,
|
|
and‘<samp>white</samp>’.
|
|
</p>
|
|
</dd>
|
|
<dt><code>set style filename intensity <var>value</var></code></dt>
|
|
<dd><p>Set the intensity to <var>value</var>. Valid intensities are ‘<samp>normal</samp>’
|
|
(the default), ‘<samp>bold</samp>’, and ‘<samp>dim</samp>’.
