WP AceEditor

As the name might hint, the plugin uses the syntax coloring schemes from the ACE code editor.

To help editors do so, the WP AceEditor plugin adds a special button to the built-in WordPress WYSIWYG editor, button which triggers a special popup box where the code can be copy&pasted or written by hand, with adjustable settings in an adjacent sidebar.

On top of this, a settings page in the WP backend also allows admins to configure site-wide syntax highlighting options as well.
