The UILangCode extension implements the {{UILANGCODE}} magic word to get interface language of the current user.


The extension can be retrieved directly from Git [?]:

  • Browse code
  • Some extensions have tags for stable releases.
  • Each branch is associated with a past MediaWiki release. There is also a "master" branch containing the latest alpha version (might require an alpha version of MediaWiki).

Extract the snapshot and place it in the extensions/UILangCode/ directory of your MediaWiki installation.

If you are familiar with Git and have shell access to your server, you can also obtain the extension as follows:

cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/UILangCode.git


  • Download and place the file(s) in a directory called UILangCode in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'UILangCode' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.



This will make the parser cache vary per user language, greatly decreasing hit rate and increasing storage.
