MediaWiki IntelliJ plugin for JetBrains PhpStorm, mostly providing standardised code styles for PHP, JavaScript, CSS and HTML. It also provides a shortcut to the MediaWiki search from the context menu.
To configure/use the MediaWiki Code Styles, go to Preferences > Editor > Code Style > PHP/CSS/Html/JavaScript, and then select "Set from..." and select "MediaWiki".
Note, this doesn't provide MediaWiki file or Wikitext syntax highlighting support.
