flask-babelex's Issues

Translations List

I need to to get translation list for only files that has the domain name "myext.mo" not all the files that ends with ".mo", I tried almost everything but I think there is no way currently.

gettext() issue

I am using flask_babelex module to translate strings in my project earlier I was using flask_babel but with Flask-Security 3.0 it comes pre-bundled and was causing conflicts with flask_babel. So I removed flask_babel and decided to use flask_babelex but it was throwing error, The given scenario below is for English to Japanese translation:

Here is the actual string:

     gettext(
         'The font size to use for the SQL text boxes and editors. '
         'The value specified is in "em" units, in which 1 is the  '
         'default relative font size. For example, to increase the '
         'font size by 20 percent use a value of 1.2, or to reduce '
         'by 20 percent, use a value of 0.8. Minimum 0.1, maximum 10.'
     )

It fails at: ../venv/lib/python3.6/site-packages/flask_babelex/__init__.py +534

with the following error:

File "/Users/admin/Documents/projects/venv/lib/python3.6/site-packages/flask_babelex/__init__.py", line 623, in gettext
   return get_domain().gettext(*args, **kwargs)
 File "/Users/admin/Documents/projects/venv/lib/python3.6/site-packages/flask_babelex/__init__.py", line 534, in gettext
   return t.ugettext(string) % variables

ValueError: unsupported format character '?' (0x5927) at index 70

Merging Flask-BabelEx back into Flask-Babel

After some discussions in the Pallets discord (where people, including myself, actually assumed that BabelEx is dead due to not having had a release in the last 4 years), I'm wondering whether it wouldn't make sense to merge back the changes from Flask-BabelEx into Flask-Babel.

As the lead developer of a project that currently uses Flask-BabelEx and the extra features it has, I'd love to see that happen (since actively maintained libs are nicer to work with, and for something as "core" as i18n having one single lib would make things more straightforward for anyone).

We can actually dedicate some developer time for this, but it would be interesting to hear your opinion on that as well, @mrjoes, since you started the fork in the first place.

Support of multiple domains

I'm using flask_user with babelex. flask_user provides i18n for its registration pages, but not for emails it's sending. I'd like to implement only translations for my custom emails, but not for the standard pages. I can provide my own domain to Babel instance. I'd like flask_user to get email translations from my custom Domain, but fall back to its own on standard pages. Having two Domains -- mine and flask_user's -- how can I merge them to the single domain and pass it to Babel?

KeyError with NumberRange validator

This issue occurs when validators have been added to a Flask-Admin field via the form_args attribute. It appeares when using the NumberRange validator but others might be concerned as well. A false validation of the NumberRange validator will result in a KeyError. This is due to the message string getting passed to gettext with formatting keys but without values.

missing git release tags

@mrjoes according to 3c9856ff989ff353c8e4ffca1f2fbd2f6fb0b74 and pypi 0.9.4 has been release. However the git tags are not reflecting any releases done. Can you please tag 0.9.4 and future release in git as well? Thanks!

Failing test: test_custom_locale_selector

When running test_custom_locale_selector I get errors of the form:

"12. April 2010 um 15:46:00 MESZ" != 12. "April 2010 15:46:00 MESZ"

I am unsure if this is a configuration problem or some underneath library changed. More context can be found at: NixOS/nixpkgs#73074

Not working with Flask-Babel?

I am using two extensions:

Flask-User (which uses Flask-Babel), and
Flask-Admin (which uses Flask-Babelex)

When I try to get i18n working for my application, I am seeing cryptic errors such as:

Is there a guide to integrating both extensions at the same time?
