Download[edit | edit source]

You can download the code directly via SVN from the MediaWiki source code repository, at http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DateDiff/. From a command line, you can call the following:

svn checkout http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DateDiff/

Installation[edit | edit source]

Place the DateDiff directory within the main MediaWiki 'extensions' directory. Then, in the file LocalSettings.php in the main MediaWiki directory, add the following line:


Use cases[edit | edit source]

A typical use case are events in a Extension:Semantic MediaWiki setup that span multiple days. In order to have the events appear on all days on the Extension:Semantic Result Formats calendar output, you would use something like:

{{#ifeq: {{{recurring}}} | no | {{#arraymap: {{#dates: | StartDate={{{from}}} | EndDate={{{till}}} }}|,|x|[[Has date::x| ]]|  }} }}
