The CodeMirror extension provides syntax highlighting in MediaWiki's wikitext editor. It adds a button with the icon to the editing toolbar that allows for switching syntax highlighting on and off. It supports the 2010 WikiEditor toolbar as well as the VisualEditor toolbar.
By default it is switched off. When switching on, it will replace the standard textarea with the editor provided by CodeMirror library. When switching off, it will be the opposite effect.
All browsers supported by MediaWiki are supported. Modern mobile browsers tend to partly work.
