| <p><a name="index-extending-GDB-1793"></a> |
| <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. |
