Project description
Muffin-Babel – an extension to Muffin that adds localization support with help of Babel.
Requirements
python >= 3.7
Installation
Muffin-Babel should be installed using pip:
pip install muffin-babel
Usage
Initialize and setup the plugin:
import muffin
import muffin_babel
# Create Muffin Application
app = muffin.Application('example')
# Initialize the plugin
# As alternative: babel = muffin_babel.Plugin(app, **options)
babel = muffin_babel.Plugin()
babel.setup(app, template_folders=['src/templates'])
# Use it inside your handlers
@app.route('/')
async def index(request):
# Get current locale
assert babel.current_locale
# Translate a text
return babel.gettext('Hello World!')Setup a locale selector function (by default the plugin is parsing accept-language header):
@babel.locale_selector
async def get_locale(request):
""" Return locale either from request.query or from request headers. """
locale = request.query.get('lang')
if not locale:
return await muffin_babel.select_locale_by_request(request, default)
return localeUse babel.gettext, babel.pgettext callables in your code:
@app.route('/')
def index(request):
return babel.gettext('Hello!')Jinja2
The Muffin-Babel has integration with Muffin-Jinja2, so if you have muffin_jinja2 plugin enabled, the plugin provides gettext and ngettext function inside the Jinja2 templates’ context.
