Fallback to cs
- Is this even possible in MediaWiki? I always thought about fallbacks as a chain, not a (possibly cyclic) graph.
- I guess it would be quite surprising for Czech users to see messages in Slovak, as this is something no other software does, I’d say. And, given both languages have quite a good coverage, I believe, it is not that necessary. OTOH, in cases where an untranslated message in English would appear, having a message in Slovak would probably be… more useful for some users? (Even though surprising, as I said.)
So, I am not sure; it’d probably not hurt a lot, at least.
Could we have a rough count of messages translated in Slovak but not in Czech (or vice versa), just for illustration?
- Yes, it's possible. We have for instance a reciprocal fallback between pt and pt-br.
- Coverage is ok for the most frequent extensions, but not for all of them. Maybe this change is going to affect/help mostly non-Wikimedia users. Is English less surprising/annoying, for the average user? (I'm not aware of data other than language proficiency statistics, to answer this question; maybe we can think of something else too?)
Special:LanguageStats/cs vs. Special:LanguageStats/sk can give an idea: MediaWiki extensions are respectively 54 % and 27 % translated, so we have at least 27 % messages in sk which would use the fallback. I'll try to make a list to see how much overlap there is.
Thanks, but it seems not to match reality in a few random tests I used. E.g. Notification-add-comment-yours2 is listed in sk and not cs, while it exists in both (and is an outdated/unused message anyway). Dtto Centralauth-editgroup-subtitle or tpt-desc. OK, User-profile-preferences-emails is in sk but not in cs, but it is unused anyway. Dtto ga-threshold. Whoa! Finally I have found Security-restricttogroup which seems to be a correct example. But the overall validity seems to be not very good by this random test.
Anyway; as I have said, I am not against the idea, just that I do not consider it that much important or useful. If someone does, by all means, go ahead.
