Integrate the UniversalLanguageSelector (ULS) into your Flask application to allow users to easily change their preferred language in which the application is rendered. It is recommended to use this in conjunction with localizing your application.

Usage

In your app.py:

from flask import Flask
from flask_uls import ULS

app = Flask(__name__)
uls = ULS(app)

You can also use the init_app pattern as well.

In your template:

<head>
{% include 'uls/head.html' %}
</head>
<body>
<span class="uls-trigger">Select language</span>
{% include 'uls/footer.html' %}
</body>

This will load the necessary CSS in the header create a button with the text “Select language” to open up the dialog menu and then load the JavaScript to configure and trigger ULS.

To integrate ULS with other localization systems, you can access the uls.language property to get the currently configured language. It will look at the ?uselang query parameter, the language cookie (set by ULS client-side), and the configured default language.

Configuration

  • ULS_DEFAULT_LANGUAGE (default: 'en'): the language to default to if the user hasn’t selected one.

  • ULS_ENABLED_LANGUAGES (default: ['en']): languages that ULS should display as options to the user.

Example

See the example application which allows users to change their language between English and German and then outputs the currently chosen language.

License

Flask-ULS is available under the terms of the GPL, version 3 or any later version.
