Problem with "Plural-forms" generated in PO file for Haitian Language

Reported by: Ed Menendez Owned by: nobody

When you makemessages for locale=ht (Haitian language), it generates a plural-form like this:

"Plural-Forms: nplurals=INTEGER; plural=EXPRESSION;\n"

It should instead look like this:

"Plural-Forms: nplurals=2; plural=(n != 1);\n"

The workaround is to manually edit the PO file after generation. If you try to use the incorrect PO file it will generate this error:

ValueError: "invalid token in plural form": EXPRESSION

Hi Ed,

When you run makemessages for the first time (i.e. a django.po file is going to be created for you), these plural form PO files header fields are copied by Django from its own .po files (found in django/conf/locale/<LOCALE NAME>/LC_MESSAGES/*.po)

There is no locally available database of plural forms formulas, nor a fancy scheme to e.g. get it from a repository.

This means Django unfortunately has no way to insert the right header there because there is no ht translation for Django itself so there is no django/conf/locale/ht/LC_MESSAGES/*.po and so the generic "Plural-Forms: nplurals=INTEGER; plural=EXPRESSION;\n" value as written by the GNU gettext CLI tools is left intact.

One workaround could be to use another locale with the same plural forms formula, like es, but then you'll have to edit the Language* fields :-(

Replying to Ramiro Morales:

...and rename the newly created es directory to ht.

The workaround causes a few undesired side effects. Assuming I'm not using "es" and I make "ht" use the "es" language code.. then the page will read <html lang="es"> for Haitian which will cause other problems.

Manually editing the PO file seems like a better workaround.

For the future though, should there be a way to provide the default header to Django for languages that aren't officially Django supported? Maybe include a /templates/locale/defaults/ht/ or something like that. Or possibly provide the needed values in a dictionary in

EDIT: I just reread that and you're saying to temporarily make it "es" and then switch the settings back. :-(

Another solution would be for Django provide instructions when you run "makemessages" so that it warns about the situation and what the workarounds are.

And what about providing a Haitian translation for Django itself?
