| <p><small>GDB</small> provides several mechanisms for extension. |
| <small>GDB</small> also provides the ability to automatically load |
| extensions when it reads a file for debugging. This allows the |
| user to automatically customize <small>GDB</small> for the program |
| being debugged. |

| |
| <p>To facilitate the use of extension languages, <small>GDB</small> is capable |
| of evaluating the contents of a file. When doing so, <small>GDB</small> |
| 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 <small>GDB</small> Command Files. |
| See <a href="Command-Files.html#Command-Files">Command files</a>. |
| </p> |
| <p>You can control how <small>GDB</small> evaluates these files with the following |
| setting: |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-set-script_002dextension"></a> |
| <a name="index-show-script_002dextension"></a> |
| </dd> |
| <dt><code>set script-extension off</code></dt> |
| <dd><p>All scripts are always evaluated as <small>GDB</small> Command Files. |
| </p> |
| </dd> |
| <dt><code>set script-extension soft</code></dt> |
| <dd><p>The debugger determines the scripting language based on filename |
| extension. If this scripting language is supported, <small>GDB</small> |
| evaluates the script using that language. Otherwise, it evaluates |
| the file as a <small>GDB</small> Command File. |
| </p> |
| </dd> |
| <dt><code>set script-extension strict</code></dt> |
| <dd><p>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. |
| </p> |
| </dd> |
| <dt><code>show script-extension</code></dt> |
| <dd><p>Display the current value of the <code>script-extension</code> option. |
| </p> |
| </dd> |
