Hey folks ,

I’m one of the maintainers of the Lotus Web library and we had a request to add i18n support for the library. The requester was nice enough to help with a PR here, but I’m having issues getting it to work locally.

If anyone has experience adding Gettext support to libraries, I could use some help understanding the following (posting here because I don’t believe this is a Phoenix-related issue):

1. Why would Gettext not pick up the correct translations, even though the locale seems to be set correctly in the LiveView process? (see PR comment for details)
2. Are we adding Gettext support to Lotus Web in the right way, with the goal of allowing users of the library to provide their own translations?
3. Is there a recommended way of adding Gettext to Elixir libraries? (I couldn’t find any suggestions in the Gettext docs).

Here’s a diff of what I’m trying (also included in the PR discussion) in another Elixir app that uses this branch:
