<p>Powerful, flexible, XHTML-compliant, server-side code highlighting, credits for everything<br />
but ‘making it a plugin’ go to <a href="http://jpipes.com/index.php?/archives/216-Syntax-Highlighting-and-Allowing-HTML-in-Comments.html" rel="nofollow ugc">Jay Pipes</a><br />

<h4>Features</h4>
<ul>
<li>Highlight sources of any language</li>
<li>automatically, server-side (no javascripts)</li>
<li>XHTML-Compliant, <code><div></code>, <code><ul></code>, <code><span></code> with class-attributes and a css-file are used for styling    </li>
<li>optionally add a heading for every code-block</li>
<li>optionally specify line-number offset (BREAKS XHTML COMPLIANCE)</li>
<li>optionally don’t display line-numbers</li>
<li>set per-codeblock if the code is html_entity_encoded or not</li>
<li>only parses <code><pre></code>-tags with the <code>lang=</code>-attribute, thus does not interfere with any regular preformatted contents you might have</li>
<li>degrades beautifully through <code><pre></code>-tags (if you keep the sources clean, that is)</li>
<li>all settings through logical, valid arguments for the main container</li>
<li>comes with generic cross-browser CSS (tested: IE5.5+, FF, Safari, Opera)</li>
</ul>
<h4>Version History</h4>
<ul>
<li>1.3: Thanks to a tipp now the link-path to the stylesheets is correct, sorry for the inconvenience</li>
<li>1.2: Leading whitespace isn’t stripped anymore (indents as well as newlines), when there’s no title the title-div is not being generated anymore</li>
<li>1.1: Solved the issue with single-quotes being changed to typographical quotes</li>
</ul>
<h4>Known Issues</h4>
<p>While the plugin is basically XHTML 1.0 Strict compliant there’s just no way of getting the offset-based line-numbering to display without inadequate (ab)use of javascript and css hacks, so be warned that <em>IF you use the line-number offset, your documents will <strong>NOT</strong> validate</em> because of the forbidden <code>start=</code>-attribute for the <code><ol></code>!</p>

<p>This project is available for forking on GitHub:</p>
<ul>
<li>https://github.com/dflydev/embed-github-gist</li>
</ul>
<p>Embed <a href="http://github.com/" rel="nofollow ugc">GitHub</a> <a href="http://gist.github.com" rel="nofollow ugc">Gists</a> into<br />
WordPress. Provides a shortcode for posts and pages but also has the ability<br />
to embed by hand in the event that a Gist needs to be embedded somewhere in<br />
the page that does not pass through the shortcode filters.</p>
<p>Examples:</p>
<pre><code>[gist id=546764]
[gist id=546764 file=file.txt]
[gist id=546764 file=file.txt bump=1]
[gist]http://gist.github.com/546764[/gist]
</code></pre>
<p>Cache is implemented with the Transients API to minimize delay on loading<br />
content. Default TTL (time to live) is 86400 seconds or one day.</p>
<h4>Upcoming features:</h4>
<ul>
<li>Option for setting default TTL</li>
<li>Option to bypass cache entirely</li>
<li>Implement admin interface to control options</li>
</ul>
