SyntaxHighlighter Evolved allows you to easily post syntax-highlighted code to your site without having to escape the code or anything. It uses the SyntaxHighlighter JavaScript package by Alex Gorbatchev to do the highlighting and supports all of the package’s parameters via shortcode attributes.

For a list of supported languages (most widely used languages are supported), see the WordPress.com support document.

If you prefer, you can hide the toolbar and line numbering with the “light” mode:

[tag light="true"]your code here[/tag]

There are many other parameters and defaults you can control via the Settings page or the shortcode parameters. Full details and instructions are located at the bottom of the Settings page.
