Internationalization

We use flask-babel for the Internationalization
I recommend to use [poedit](https://poedit.net/)
- We followed the instructions on: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xiii-i18n-and-l10n

Include new internationalized text snippets:

Add a snippet similar to this <p><b>{{ _(‘Hinweis:’) }}</b></p> in any of the html-files under /templates. .. code-block:: shell

$ source ~/envs/bin/activate (envs) $ pybabel compile -d translations (envs) $ pybabel extract -F babel.cfg -k _l -o messages.pot . (envs) $ pybabel update -i messages.pot -d translations (envs) $ pybabel compile -d ./translations

How to update existing existing text blocks:

should result in this terminal output: .. code-block:: shell

compiling catalog ./translations/en/LC_MESSAGES/messages.po to ./translations/en/LC_MESSAGES/messages.mo compiling catalog ./translations/fr/LC_MESSAGES/messages.po to ./translations/fr/LC_MESSAGES/messages.mo
