Manual:$wgDefaultLanguageVariant/fr

Détails
Default variant code, if false, the default will be the language code. Only works when it is defined as a variant in the class of that language.

Utilisation
In LocalSettings.php, one may set:

= "sr"; $wgDefaultLanguageVariant = "sr-el";

This will use Serbian system messages in Latin-script, but report for javascript the simple contentlanguage="sr".
