<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.
|
|
|
|
<dl>
|
|
<dt><code>show language</code><dd><a name="show-language"></a><a name="index-show-language-968"></a>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.
|
|
|
|
<br><dt><code>info frame</code><dd><a name="index-info-frame_0040r_007b_002c-show-the-source-language_007d-969"></a>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.
|
|
|
|
<br><dt><code>info source</code><dd><a name="index-info-source_0040r_007b_002c-show-the-source-language_007d-970"></a>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.
|
|
</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:
|
|
|
|
<dl>
|
|
<dt><code>set extension-language </code><var>ext</var> <var>language</var><dd><a name="index-set-extension_002dlanguage-971"></a>Tell <span class="sc">gdb</span> that source files with extension <var>ext</var> are to be
|
|
assumed as written in the source language <var>language</var>.
|
|
|
|
<br><dt><code>info extensions</code><dd><a name="index-info-extensions-972"></a>List all the filename extensions and the associated languages.
|
|
</dl>
