|
|
<span class="sc">gdb</span> provides several mechanisms for extension.
|
|
<span class="sc">gdb</span> also provides the ability to automatically load
|
|
extensions when it reads a file for debugging. This allows the
|
|
user to automatically customize <span class="sc">gdb</span> for the program
|
|
being debugged.

</ul>
|
|
|
|
<p>To facilitate the use of extension languages, <span class="sc">gdb</span> is capable
|
|
of evaluating the contents of a file. When doing so, <span class="sc">gdb</span>
|
|
can recognize which extension language is being used by looking at
|
|
the filename extension. Files with an unrecognized filename extension
|
|
are always treated as a <span class="sc">gdb</span> Command Files.
|
|
See <a href="Command-Files.html#Command-Files">Command files</a>.
|
|
|
|
<p>You can control how <span class="sc">gdb</span> evaluates these files with the following
|
|
setting:
|
|
|
|
|
|
<a name="index-set-script_002dextension-1794"></a>
|
|
<a name="index-show-script_002dextension-1795"></a>
|
|
<dl><dt><code>set script-extension off</code><dd>All scripts are always evaluated as <span class="sc">gdb</span> Command Files.
|
|
|
|
<br><dt><code>set script-extension soft</code><dd>The debugger determines the scripting language based on filename
|
|
extension. If this scripting language is supported, <span class="sc">gdb</span>
|
|
evaluates the script using that language. Otherwise, it evaluates
|
|
the file as a <span class="sc">gdb</span> Command File.
|
|
|
|
<br><dt><code>set script-extension strict</code><dd>The debugger determines the scripting language based on filename
|
|
extension, and evaluates the script using that language. If the
|
|
language is not supported, then the evaluation fails.
|
|
|
|
<br><dt><code>show script-extension</code><dd>Display the current value of the <code>script-extension</code> option.
