CodeMirror is currently being upgraded to a new major version. See Extension:CodeMirror/6 for the new documentation.

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 switched on, it will replace the standard textarea with the editor provided by CodeMirror library. When switched off, it will switch back to the standard textarea.

The colors used in this extension have been optimised for higher contrast, accessibility and better readability and now conform to the Web Content Accessibility Guidelines (WCAG 1.4.3 AA). The colors provide better access for people with limited vision as well as for users working in bright daylight conditions. (more information)

Bracket matching

This feature highlights the innermost pair of brackets when the cursor lies between any bracket pair, and when the cursor lies directly next to a bracket, the feature highlights the corresponding matching bracket. Bracket matching is 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.

This feature is enabled only for the template namespace on most wikis, and on all namespaces on some wikis (see the roadmap and the configuration).

Colorblind mode

For users who have difficulty distinguishing between colors, CodeMirror offers a colorblind-friendly mode. This feature can be activated on wikis with CodeMirror enabled by navigating to the Special:Preferences page.

With the colorblind-friendly scheme active, the colors of the following page elements change:

Headings, symbols, signatures, section names, magic words #E4A400
Templates #9C3A00
HTML tags, references, mathematical expressions #56B4E9
Zmienne #009E73

In addition, background highlights and colors are removed from all text and objects. Bolding and underlining behavior remains unaffected.

Browser support

All browsers supported by MediaWiki are supported.


  • Install either the WikiEditor extension or the VisualEditor extension, as instructed on their pages; at least one of these is required for this extension to work.
  • Pobierz i umieść plik(i) w katalogu o nazwie CodeMirror w folderze extensions/.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CodeMirror
  • Dodaj poniższy kod na dole twojego pliku LocalSettings.php :
    wfLoadExtension( 'CodeMirror' );
  • Configure as required.
  •   Zrobione – Przejdź do Special:Version na twojej wiki, aby sprawdzić czy rozszerzenie zostało pomyślnie zainstalowane.

Instalacja Vagranta:

  • Jeżeli korzystasz z Vagrant a, zainstaluj poprzez vagrant roles enable codemirror --provision


For color and style customization, see Meta help page. You can use your own styles for wikitext highlighting. Used styles available here. You should place your own styles to common.css .

Add the following code at the bottom of your LocalSettings.php .

# Enables use of CodeMirror by default but still allow users to disable it
$wgDefaultUserOptions['usecodemirror'] = true;

Additional configuration:

Restrict line numbering to specific namespaces. Defaults to null, which enables it for all namespaces. Set to [] to disable everywhere.
Temporary feature flag to control the migration to CodeMirror 6 (phab:T259059).
An array of gadget names that, if enabled, will prevent CodeMirror from loading. Defaults to wikEd.

Extension integration

This functionality is subject to change following the CodeMirror 6 upgrade. See Extension:CodeMirror/6#Integration for documentation on CodeMirror 6.

If your MediaWiki extension adds a new tag and you want to make sure CodeMirror properly highlights the content within it, you can add CodeMirror support to your extension. Here are two examples: Cite extension and PhpTags extension.

JavaScript integration

The following front-end hooks are used in this extension:

Hook Parameters
Type Description
ext.CodeMirror.switch boolean Whether the CodeMirror editor is now shown
jQuery object The current "editor", which is either the normal ‎<textarea /> or the .CodeMirror element.

If you need to interact with the contents of a CodeMirror instance, use jQuery.plugin.textSelection.
