Extension:CodeMirror/en

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.

The colors used in this extension have been optimised to provide higher contrast, accessibility and better readability.

Bracket matching
This feature allows highlighting of the closest matching pair of surrounding brackets while navigating through wikitext code using the cursor. Bracket matching will be active in both editors when syntax highlighting is turned on, in any namespace using these editors.

Line numbering
In the wikitext edit mode line numbers are automatically displayed in both editors.

Browser support
