I’m using Gettext’s dgettext(domain, msgid) function to organize my translation files (referred to as “domains” in the documentation).

I want to go further and also organize the domain files into sub-folders.

Using dgettext("path/domain", msgid) does create gettext/path/domain.pot. It doesn’t create the file in gettext/en/LC_MESSAGES/path/domain.pot or in any of the other locales and also gives this error:

18:35:43.237 [error] Task #PID<0.433.0> started from #PID<0.88.0> terminating
** (Gettext.Plural.UnknownLocaleError) unknown locale "path". If this is a locale you need to handle,
consider using a custom pluralizer module instead of the default
Gettext.Plural. You can read more about this on the Gettext docs at
https://hexdocs.pm/gettext/Gettext.Plural.html

I have a mix task that I run when generating .pot files:
translate: ["gettext.extract", "gettext.merge priv/gettext"]

So, is it possible to organize .pot files in sub-folders as I’m trying to do ?
