<p>Powerful, flexible, XHTML-compliant, server-side code highlighting, credits for everything<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>

SyntaxHighlighter Evolved

Just what I was looking for.
Thank you guys.

Perfect

I'm a longtime user of syntaxhighlighter evolved, so thanks for the excellent plugin!

The only downside I've recently experienced is the lack of bbPress integration, hence 4 stars rather than 5. If you need this for non-bbPress projects, this is a great choice.

longtime fan, but no bbpress support


It works and show code beautifully on pages, But if you copied that code and want to use it, the it shows errors, Looks like it add some spaces,



I tried it with php shorcode, and when i copied the code from the frontend of the page, It gives Parse error: syntax error, unexpected...


Works, But if you copy code and wan to to use it show error

Easily post syntax-highlighted code to your site without having to modify the code at all. As seen on WordPress.com.
