Muffin-Babel

Requirements

• python >= 3.9

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 locale

Use 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.

Options

You are able to provide the options when you are initiliazing the plugin:

babel.setup(app, default_locale='fr')

Or setup it inside Muffin.Application config using the BABEL_ prefix:

BABEL_DEFAULT_LOCALE = 'fr'

Muffin.Application configuration options are case insensitive

Commands

The plugin adds two commands to your Muffin application.

Extract messages

Extract strings from your application to locales: :

$ muffin app_package babel_extract_messages [OPTIONS] appdir

Translate .po files and compile translations: :

$ muffin app_package babel_compile_messages [OPTIONS]
