This module provides a method for prompt value-substitution.
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>substitute_prompt (</code><var>string</var><code>)</code><dd>Return <var>string</var> with escape sequences substituted by values. Some
|
||
|
|
escape sequences take arguments. You can specify arguments inside
|
||
|
|
“{}” immediately following the escape sequence.
|
||
|
|
|
||
|
|
<p>The escape sequences you can pass to this function are:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>\\</code><dd>Substitute a backslash.
|
||
|
|
<br><dt><code>\e</code><dd>Substitute an ESC character.
|
||
|
|
<br><dt><code>\f</code><dd>Substitute the selected frame; an argument names a frame parameter.
|
||
|
|
<br><dt><code>\n</code><dd>Substitute a newline.
|
||
|
|
<br><dt><code>\p</code><dd>Substitute a parameter's value; the argument names the parameter.
|
||
|
|
<br><dt><code>\r</code><dd>Substitute a carriage return.
|
||
|
|
<br><dt><code>\t</code><dd>Substitute the selected thread; an argument names a thread parameter.
|
||
|
|
<br><dt><code>\v</code><dd>Substitute the version of GDB.
|
||
|
|
<br><dt><code>\w</code><dd>Substitute the current working directory.
|
||
|
|
<br><dt><code>\[</code><dd>Begin a sequence of non-printing characters. These sequences are
|
||
|
|
typically used with the ESC character, and are not counted in the string
|
||
|
|
length. Example: “\[\e[0;34m\](gdb)\[\e[0m\]” will return a
|
||
|
|
blue-colored “(gdb)” prompt where the length is five.
|
||
|
|
<br><dt><code>\]</code><dd>End a sequence of non-printing characters.
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>For example:
|
||
|
|
|
||
|
|
<pre class="smallexample"> substitute_prompt (``frame: \f,
|
||
|
|
print arguments: \p{print frame-arguments}'')
|
||
|
|
</pre>
|
||
|
|
<p><br>will return the string:<br>
|
||
|
|
|
||
|
|
|
||
|
|
<pre class="smallexample"> "frame: main, print arguments: scalars"
|
||
|
|
</pre>
|
||
|
|
</dl>
