Why is this feature turned off on the english-language wikipedia ? And the german and french language.
Topic on Talk:Universal Language Selector/Compact Language Links
Also Swedish and Dutch.
These are bigger projects with more users, so it requires a bit more planning, but it will definitely be enabled in the coming weeks. Announcements with dates will be published soon.
In the meantime, it can be enabled as a beta feature, and we'll be very happy to listen to the feedback.
@Amire80: And how about Meta-Wiki? I even can't try it out?
It's not on Meta because Meta doesn't have different language versions in the same way that Wikipedia does.
Technically, the preferences doesn't appear anywhere at Meta, because $wgInterwikiMagic is set to false there. If I understand correctly, pre-Wikidata interlanguage links like [[fr:Accueil principal]] won't go to the sidebar without $wgInterwikiMagic. Meta can have Wikidata sitelinks, however, which is why the Meta Main page has interlanguage links, but where else does Meta have them?
I guess that Compact Language Links could be enabled on Meta if the use case on Meta is comparable to Wikipedia. (And on a more technical note, maybe $wgInterwikiMagic could be set to true now that we've had Wikidata for years, but that would be a separate discussion.)
"but where else does Meta have them?" at least Meta:Babel and Assume good faith.
Cool, thanks for the example. These definitely needs improvement, and Compact Language Links could one way to resolve it.
Took me some time, but I filed a task about this: https://phabricator.wikimedia.org/T202284
It's possible now to use Compact Language Links on English and all other Wikipedias, as well as on Meta, but wgInterwikiMagic is still false for meta for some reason, so maybe it should be changed.
Thanks for raising this, @Liuxinyu970226.
