asgi-babel -- Adds internationalization (i18n) support to ASGI applications (Asyncio / Trio / Curio)
Contents
- python >= 3.9
asgi-babel should be installed using pip:
pip install asgi-babel
Common ASGI applications:
from asgi_babel import BabelMiddleware, current_locale, gettext
async def my_app(scope, receive, send):
"""Get a current locale."""
locale = current_locale.get().language.encode()
hello_world = gettext('Hello World!').encode()
await send({"type": "http.response.start", "status": 200})
await send({"type": "http.response.body", "body": b"Current locale is %s\n" % locale})
await send({"type": "http.response.body", "body": hello_world})
app = BabelMiddleware(my_app, locales_dirs=['tests/locales'])
# http GET /
#
# Current_locale is en
# Hello World!
# http GET / "accept-language: ft-CH, fr;q-0.9"
#
# Current_locale is fr
# Bonjour le monde!As ASGI-Tools Internal middleware
from asgi_tools import App
from asgi_babel import BabelMiddleware, gettext
app = App()
app.middleware(BabelMiddleware.setup(locales_dirs=['tests/locales']))
@app.route('/')
async def index(request):
return gettext('Hello World!')
@app.route('/locale')
async def locale(request):
return current_locale.get().languageThe asgi-babel uses context variable to set current locale. To enable the
context variables with curio you have to run Curio with contextvars
support:
from curio.task import ContextTask
curio.run(main, taskcls=ContextTask)The middleware's options with default values:
from asgi_babel import BabelMiddleware
app = BabelMiddleware(
# Your ASGI application
app,
# Default locale
default_locale='en',
# A path to find translations
locales_dirs=['locales']
# A function with type: typing.Callable[[asgi_tools.Request], t.Awaitable[t.Optional[str]]]
# which takes a request and default locale and return current locale
