Flask-Banana 0.1.2

Usage

In your app.py:

from flask import Flask
from flask_banana import Banana
from pathlib import Path

app = Flask(__name__)
banana = Banana(app, Path(__file__).resolve().parent / 'i18n')

You can also use the init_app pattern as well.

In your template the _(...) function is aliased to banana.translate():

<body>
<p>{{ _('some-message-key') }}</p>
</body>

To change the language, set the banana.language property. You might also want to try the Flask-ULS library for better client-side support for changing the interface language.

Flask-ULS integration

Flask-Banana can automatically configure and integrate with Flask-ULS, just pass the ULS instance to Banana during setup:

app = Flask(__name__)
uls = ULS(app)
banana = Banana(app, Path(__file__).resolve().parent / 'i18n', uls)

Banana will configure ULS to enable all of the languages that have translations and then default to using the language configured through ULS.

Configuration

• BANANA_DEFAULT_LANGUAGE (default: 'en'): the language to default to if one hasn’t been manually set through Banana nor ULS.
