What can this extension do?[edit]

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 comparision 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:
wfLoadExtension( 'DoubleWiki' );
  • YesY 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 extensions using wfLoadExtension(), since MediaWiki 1.25. If you need to install this extension in earlier versions, 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.
