  • Support temporary language switch inside a request

    Support temporary language switch inside a request

    It would be nice to be able to stash the current language somewhere and use another one for a while during a request execution.

    The main use-case I see is sending out emails with Flask-Email. The email should be translated according to the recipient's language and not the current user's language.

    Something like:

    from flaskext.babel import stash, unstash
    
    # do stuff with current user's language
    print _('foo')
    # Now switch to th recipient language
    stash(new_lang=recipient.language)
    send email with i18n tags
    unstash()
    # Now the language is back to the current user's lang
    

    Well the API is terrible, but you get the idea..

  • do not hardcode the translations folder path

    do not hardcode the translations folder path

    This allows to specify in which folder the translations should be looked for instead of having it hardcoded (still defaults to "translations"). This is done either via a folder param passed to the constructor or via the BABEL_TRANSLATIONS_FOLDER configuration variable.

    Documentation request - using templates

    There should be a short introduction in how to use gettext, trans etc in Jinja the jkji2 templates - it's not obvious from the docs that the jinja2 i18n ext is used and that the user does not need to configure this separately.

  • Fix locale selection in multi-threaded Flask app when force_locale is used

    Fix locale selection in multi-threaded Flask app when force_locale is used

    This fixes issue #117 by setting babel_locale in force_locale context manager instead of replacing locale getter. Babel extension instance is shared across threads (through Flask.extensions) which may cause wrong locale to be selected in request that is processed at the same time in one thread while another thread is using force_locale. Setting locale to request context is thread-safe as Flask doesn't share request contexts between threads. I've added a test case to verify that this fix works, and it failed without changes to force_locale.

  • Add basic support for locales unkown by Babel

    Add basic support for locales unkown by Babel

    Right now Flask breaks if you request content in a locale that is unknown by Babel even if the translation files actually exist.

    This commit allows translations to be loaded even if the locale is unknown by Babel. Numbers and datetimes ~are returned directly~ use the default locale as a fallback.

  • 'Babel' object has no attribute 'translation_directories'

    'Babel' object has no attribute 'translation_directories'

    I am getting a:

    'Babel' object has no attribute 'translation_directories'

    error after updating Flask-Babel from 0.9 to 0.11.1.

    I found a similar reference at https://github.com/airbnb/superset/issues/847 which claims the issue was flask extension compatibility related.

    I have been looking for any sort of documentation that indicates what flask extensions have compatibility with one another, is it just assumed that the minor version (major.minor.build) must match to be compatible?

    Here are my current application versions that are having the issue:

    Babel (2.3.4) Flask (0.11.1) Flask-Babel (0.11.1) Flask-BabelEx (0.9.3) Flask-Compress (1.3.2) Flask-Login (0.4.0) itsdangerous (0.24) Jinja2 (2.8) MarkupSafe (0.23) pytz (2016.7) setuptools (28.8.0) speaklater (1.3) Werkzeug (0.11.11)

    Again, all works with version 0.9 of flask-babel, just trying to understand if compatibility is the root cause or is there a real issue lurking.

  • how to correctly work out of context

    how to correctly work out of context

    Hi, all. I have two subprocesses. one for flask web(called web.py), and one for some background tasks(called task.py). flask-babel works inside the web context, but also the task subprocess will need some translations. so, I import web app into the task.py and use the app.test_request_context in order to make translations work for me. it works at first but then I found task.py will also get the default language only. here is the web.py:

    app.config['BABEL_DEFAULT_LOCALE'] = 'en'
    babel = Babel(app)
    
    @babel.localeselector
    def get_locale():
        return request.accept_languages.best_match(['zh', 'en'])
    

    task.py

    from web import app
    def task():
        try:
            with app.test_request_context() as ctx:
                sio.emit('loading', {'data': _("please wait a moment.")})
    ....
    

    so how can I get the correct locale before I return the translation?? TIA :)

    question about .mo file caching mechanism

    Hi there

    I have a question So we all know that .mo will be cached in flask app I just want to know if when we run flask server it caches all .mo files at the beginning? Or is it just when we switch languages then it creates domain objects and caches that .mo file?

    I thought caching all mo files at the beginning would minimize IO time
