DoubleWiki allows you to compare wikis in two separate languages side by side.

For an example, see http://fr.wikisource.org/wiki/Criton_(trad._Cousin)?match=en. See Wikisource:DoubleWiki Extension for more information.


Appending ?match=<lang code> (or &match=<lang code>) to a url allows you to see a side by side comparison of a page with the same page in another language.

You can use an empty div with a title attribute (for example <div title="some title"/>) to force certain sections to line up.

This extension was made especially for Wikisource (see also bugzilla:4104). For full information on this extension, it is recommended you read the page at wikisource - oldwikisource:Wikisource:DoubleWiki Extension Comments/questions/etc should go on the Wikisource page.


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

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'DoubleWiki' );, you need to use:

require_once "$IP/extensions/DoubleWiki/DoubleWiki.php";

Configuration parameters[edit]

This extension has no configuration parameters, but expects interlanguage links to be configured appropriately. See Interlanguage links and Manual:Interwiki#Interwiki links to other languages. You should ensure all your interlanguage (not interwiki) links are to websites you control, as this extension will load pages from these other language links.
