Fallback chain for sibling specificity in languages
XAMPPRocky opened this issue · comments
So basically going for the proposed solution from #1 this results in the fallback key to be present in the base zh language.
I am not sure if we should change that to have a resolution order like:
zh-CN -> zh-CN, zh-TW, zh, default_fallback
The question then would be: What to do with a specificity higher than 2?
de-DE-1996 -> de-DE-1996, [de-CH-VARIANT], de-DE, de-CH, de, default_fallback
?
Not sure how the best approach should be.
If we consider the current state as a linked list, other language regions like CH would then be siblings in a tree.
The question is how many branches of the main path between the requested one and the root should be visited.
fallback <- de <- de-DE <- de-DE-1996
Î ^- de-DE-VARIANT2
\ de-CH <- de-CH-VARIANT
In which order should they be visited?
And what about multiple requested languages? (possibly with weights), can we ignore them for now? I guess currently one can argue that this is only localization resolution and language negotiation should be done ahead.
