Where does django's makemessages keep the list of locales for --all option

Question

Django's manage.py makemessages function can be used with the option --all (or -a), which makes po files for all the locales that have been previously given to makemessages as -l options. Does anyone know where does makemessages get this list? I know it's not from the LANGUAGES tuple in the project settings module because locale folders for languages in there only show up after I explicitly add them at least once with makemessages -l <locale> .

Answer 1

it does take the locales from LANGUAGES in settings.py

if you makemessages -all or makemessages -a , it creates locale folders for ALL languages which are given in LANGUAGES

Quote from docs:

Use the --all or -a option to update the message files for all available languages.

in Django, as far as I know, all available languages can be only given thru LANGUAGES in settings.py
