Comment 0 for bug 1003818

Both 'quickly package --extras' and 'quickly submitubuntu' correctly install translations for applications in /opt/extras.ubuntu.com/appname/share/locale.

However, there is an additional step required to make applications to actually use those translations at runtime: use the bindtextdomain() call to specify that they should be loaded from /opt instead of /usr/share/locale.

Quickly's gettext setup is originally:

import gettext
from gettext import gettext as_
gettext.textdomain('appname')

And this should be changed to the following for apps in extras:

TEXTDOMAIN = 'appname'
LOCALEDIR = '/opt/extras.ubuntu.com/appname/share/locale'
import locale
from locale import gettext as _
locale.bindtextdomain(TEXTDOMAIN, LOCALEDIR)
locale.textdomain(TEXTDOMAIN)

Notice the use of the locale module (Python's C gettext API) instead of the gettext module (pure Python gettext API). This is needed to make Gtk.Builder() load translations in /opt.

I wonder whether the gettext initialization could be moved to a single place/module, rather than added to each .py file as it is done now. This would probably help if the implementation of 'quickly package --extras' or 'quickly submitubuntu' would rely on adding a patch to modify those lines of code or simply do text substitution.

This still does not take care of the translations for schemas and PolicyKit files in /opt (they should be filed as separate bugs), but at least gets us 90% there in being able to run localized apps from /opt
