Preferred Language "de-DE" (in Openstreetmap.org/My Settings/Preferred Languages) is not recognised as German while "de" is

[manfredbrandl]

User Interface is german in the first line und Englisch in der zweiten Zeile.

I have the same problem with Firefox 35.0.1 on Windows 7.

If I set Openstreetmap.org . "My Settings" / "Einstellungen" .

• "Preferred Languages" / "Bevorzugte Sprachen:" to "de-DE"

THEN I get similar result.
But with "Preferred Languages" = "de" is OK.

Can you provide

• Your browser language code? http://bl.ocks.org/ansis/0bd4911cd6bcc6395e7e
• Your Openstreetmap.org "Preferred Languages"` = ?

maybe related to this #723

2 language file exists:

• ./dist/locales/de.json
• ./dist/locales/de-DE.json -- empty

My browser language is "DE".
My OpenStreetMap preferred Languages is "de-DE,de,en-US,en" (don't ask my why :-))

[TheFive]

switching to the preferred language "de" will work for ID.
I do not know, if they are some implications of this change to other OSM App. (I do not know the difference between DE-DE and DE, either)

[manfredbrandl]

My OSM-Language-Settings were "de-DE,de,en-US,en", After changing to "de,de-DE,en-US,en" iD shows the German menu. My browser language code is "en-US".

It looks like the last time I ran make translations it pulled down an empty
de-DE.json file (and others) from Transifex.

The quick fix is to just remove the empty files.. The better fix is maybe: if detecting a culture code (e.g. de-DE), also load in the language code (de), and use it as a fallback in the t() function.

@jfirebaugh thoughts?

[jfirebaugh]

Ideally we would follow the user's preferred fallback order, e.g. de-DE,de,en-US,en, but we might have to balance that with not making too many requests for individual files.

[bhousel]

The rails site is only sending us the first one from the list...
(though we could change that)

[tomhughes]

It is probably better for you to be consistent with what we do for the web site code though - we select the primary locale by matching against the user's list but once we have done that we don't do any fallback along that list. We do however fallback from de-DE to de.

Falling back along the user's language list could give really weird results if they have listed a number of unrelated languages that they happen to speak.

So basically we choose a language, and set it in I18n.locale and then relay on I18n::Backend::Fallbacks to do the fallbacks, which just falls back to parent locales basically (one exception is that we add a mapping from no to nb to cope with Norwegian weirdness) and then eventually to english.

[tomhughes]

For now I have removed all the empty locales from iD in the web site repository, namely:

• vendor/assets/iD/iD/locales/de-DE.json
• vendor/assets/iD/iD/locales/en-DE.json
• vendor/assets/iD/iD/locales/gan.json
• vendor/assets/iD/iD/locales/hi-IN.json
• vendor/assets/iD/iD/locales/km.json
• vendor/assets/iD/iD/locales/km-KH.json
• vendor/assets/iD/iD/locales/nn.json
• vendor/assets/iD/iD/locales/ru-RU.json
• vendor/assets/iD/iD/locales/sq-AL.json
• vendor/assets/iD/iD/locales/sq.json
• vendor/assets/iD/iD/locales/sr-RS.json
• vendor/assets/iD/iD/locales/zh-CN.GB2312.json

[jfirebaugh]

I've removed de-DE, en-DE, km-KH, ru-RU, sq-AL, sr-RS, and zh-CN.GB2312 on Transifex -- those were probably a misunderstanding. Keeping the empty language code ones, someone might actually want to start translating those. We might want to drop empty translations in the processing script on the iD side though.

[manfredbrandl]

Now the behavior is as expected on www.openstreetmap.org. Just tested for de-DE. Who does close this issue?

The issue can stay open, because removing the empty translation files is not a permanent fix. (It may pop up again next time we release).

I have created a simple statisctics from changesets for iD Editor - locale :
