Any way to detect current langage in utils ? #1

Open pyladune opened 7 years ago

pyladune commented 7 years ago

This implementation is pretty nice but would there be a as nice way to detect the language selected by user inside the utils functions ? The point is to be able to use translate function in submodule without passing the main model each time just for that

You don't need to pass all the model, just the language and the string ID.

Yes, but how to access to currentlanguage directly from utils.elm instead to pass it at each call of translate ? that would make the whole thing easier i think

You can't, because in Elm you always pass arguments around. No global state.

One way to just pass the string ID to the translate function would be to curry it beforehand, and then you can pass the curried translate function down to the submodule where you need it.

pyladune commented 7 years ago

@simonewebdesign could you explain more or illustrate, seems interresting but don't get it at all :-)

simonewebdesign commented 7 years ago

@pyladune The translate function has this signature:

translate : Language -> TranslationId -> String

Curried:

curriedTranslate : TranslationId -> String
curriedTranslate trans =
    translate currentLanguage trans

currentLanguage : Language
currentLanguage =
    Japanese

At this point you can just use it anywhere without carrying the currentLanguage about :)
