Dottoro Highlighter plugin is based on the <a href="http://tools.dottoro.com/services/highlighter/docs/plugins.php" rel="nofollow ugc">Dottoro Syntax Highlighter</a> service that provides professional coloring for CSS, HTML, JavaScript and XML languages. 
It supports highlighting CSS, JavaScript and XML blocks embedded into HTML documents, optionally selectable line numbering and buttons for copying and printing code snippets. 
It performs a detailed lexical analysis on the source code and attaches different style classes for different language items, thus providing a very flexible way to modify the appearance of the highlighted code.
Using of the Dottoro Highlighter plugin is really simple. Just insert your code snippet in the Visual or HTML view, select it and press the Dr-Highlight button on the toolbar. 
You don’t need to embed your source code into an element (such as PRE), just select the whole source that you want to highlight and press the Dr-Highlight button. 
Clicking on the Dr-Highlight button pops up a dialog box where you can specify the settings for the highlighted code. 
If you need to modify the appearance of a previously highlighted code, click into it then click on the Dr-Highlight button on the toolbar.
The default settings for the Dottoro Highlighter plugin can be set on the preferences page.

I've been waiting for years for such a plugin! Pastacode is easy to use, well coded and looks gorgeous with any WordPress theme. Keep going!



Best plugin to embed code

Just started using this plugin, but I'm quickly becoming a big fan. Not only does this allow you to embed & highlight the normal stuff, but it will also fetch and embed directly from a github/bitbucket repo. Awesome work!

Great code embed & syntax highlighting plugin
