| <h3 class="section">15.2 Displaying the Language</h3> |
| |
| <p>The following commands help you find out which language is the |
| working language, and also what language source files were written in. |
| </p> |
| <dl compact="compact"> |
| <dt><code>show language</code></dt> |
| <dd><a name="show-language"></a><a name="index-show-language"></a> |
| <p>Display the current working language. This is the |
| language you can use with commands such as <code>print</code> to |
| build and compute expressions that may involve variables in your program. |
| </p> |
| </dd> |
| <dt><code>info frame</code></dt> |
| <dd><a name="index-info-frame_002c-show-the-source-language"></a> |
| <p>Display the source language for this frame. This language becomes the |
| working language if you use an identifier from this frame. |
| See <a href="Frame-Info.html#Frame-Info">Information about a Frame</a>, to identify the other |
| information listed here. |
| </p> |
| </dd> |
| <dt><code>info source</code></dt> |
| <dd><a name="index-info-source_002c-show-the-source-language"></a> |
| <p>Display the source language of this source file. |
| See <a href="Symbols.html#Symbols">Examining the Symbol Table</a>, to identify the other |
| information listed here. |
| </p></dd> |
| </dl> |
| |
| <p>In unusual circumstances, you may have source files with extensions |
| not in the standard list. You can then set the extension associated |
| with a language explicitly: |
| </p> |
| <dl compact="compact"> |
| <dt><code>set extension-language <var>ext</var> <var>language</var></code></dt> |
| <dd><a name="index-set-extension_002dlanguage"></a> |
| <p>Tell <small>GDB</small> that source files with extension <var>ext</var> are to be |
| assumed as written in the source language <var>language</var>. |
| </p> |
| </dd> |
| <dt><code>info extensions</code></dt> |
| <dd><a name="index-info-extensions"></a> |
| <p>List all the filename extensions and the associated languages. |
| </p></dd> |
| </dl> |
