Extension:Interwiki


 * This extension should not be confused with Extension:InterWiki.

This is an extension to add a Special:Interwiki page to MediaWiki, to view and edit the interwiki table, and a log of any actions made with it. It was made by Stephanie Amanda Stevens a.k.a Phroziac, because she was annoyed at forgetting the interwiki prefixes.

Since Interwiki version 2.1, it works with the $wgInterwikiCache, and the CSS uses ResourceLoader. This version is only compatible with MW 1.19+.

The list of Special:Interwiki is identical to the API action=query&meta=siteinfo&siprop=interwikimap.

Installation
Notes:
 * The configuration that comes with MediaWiki will not grant permission to any user group. Thus, you will need to add the configuration yourself or no one will be able to edit interwikis.
 * To enable transclusion from other sites, you'll need to enable.
 * To disable adding prefixes through the Special:Interwiki interface, set $wgInterwikiViewOnly to true.

Setting up interlanguage links
To set up interlanguage links using this extension, make sure that $wgInterwikiMagic is set to true and $wgHideInterlanguageLinks is set to false (they are like this by default, you don't need to change them usually). Then go to Special:Interwiki as a user with the appropriate permissions. For example, if the French version of your wiki was located at  http://fr.foowiki.tld/wiki/ , you could add  http://fr.foowiki.tld/wiki/$1  to the interwiki table with values trans 0 and local 0. Then the interlanguage link to the French version would work, but a #REDIRECT to a French-language page from a page in some other language would be refused.

See Manual:Interwiki table for a full explanation of the forward (iw_local) and transclude (iw_trans) bits.

In brief:
 * Enabling forwarding ('local' true) is normally done between all languages and projects in the same group, as it allows a link to any one of the languages to be used as a gateway to the others. The English-language Wikipedia, for instance, sets the 'local' bit true for all of the other-language Wikipedias and for projects like commons:, wikinews: or wikivoyage:. A user on a wiki outside Wikipedia where the wikipedia: interwiki prefix points to en.wikipedia.org could create a link like Encyclopédie. That link goes initially to "fr:Encyclopédie" on the English-language Wikipedia. The en.wikipedia server immediately recognises fr: as a 'local' interwiki link, so replies with a redirect to la Wikipédia where fr.wikipedia.org/wiki/Encyclopédie displays the requested French-language Wikipédia page Encyclopédie et voilà.
 * Enabling transclusion is rarely done, as it allows an article on one wiki to use templates from some other wiki. This is referred to as 'scary transclusion' as it will cause problems if the other wiki changes the template unexpectedly. A few wiki farms use this to create one 'central wiki' with various templates which are made available to other wikis in the same farm. If you don't need this, don't enable it.

Protocol-relative URLs
MediaWiki supports protocol-relative URLs (PRURLs), beginning with version 1.18. To use PRURLs, simply remove the  portion of the URLs in the default link table. Ensure the server supports HTTPS before you do that. For example, this

http://en.wikipedia.org/wiki/$1

should be changed to this:

//en.wikipedia.org/wiki/$1
