There are 2 situations:
- MediaWiki 1.23 that are migrated: the default language must be migrated. It can be done with the parameter language at registration time.
- New MediaWiki created with the standalone version: they are init with Tuleap defined
sys_lang
It's no longer possible to init a MW with a language different from Tuleap platform default. The language selection at the init seems to be an unnecessary step at this point (it's the only place where you have to choose the language).
Default language has 2 consequences:
- The name and the content of the default page change (eg
Accueil
in french vs Main_Page
in english).
- Some part of the wikitext can be used in their localized version (eg
[[Categorie]]
in french vs [[Category]]
in english). Note: english version is always usable.
The interface is always displayed with User's lang, regardless of the init.
If we ever need to re-introduce the lang selector:
- Switching from English to something else has no impact (because english is canonlical, wikitext written in english will always work)
- Switching from another language to English might have an impact if localized wikitext was used
