Importer code changes in 2.1.44/45/46

[mbz20]

I wrote an (https://ankiweb.net/shared/info/1199027445), many years ago, that allows importing latex files (*.tex). This worked up until at least Anki version 2.1.43. It seems that one of the versions 2.1.44/2.1.45/2.1.46 introduced some essential changes in core anki regarding importers. In the current version, I get the following error message on startup if my addon is loaded:

An add-on you installed failed to load. If problems persist, please go to the Tools>Add-ons menu, and disable or delete the add-on.

When loading '<U+2068>LaTeX Note Importer<U+2069>':

I have checked the documentation here:

Add-on porting notes for Anki 2.1.45

Some porting notes for add-ons wanting to support Anki 2.1.45: (this has been made a wiki post - please add anything you feel would be useful here, and if you don’t have permission, please reply below) Type Hints A reminder that most of Anki’s codebase now has type hints, and you can easily install Anki packages (including betas) with ‘pip install’. Instead of just clicking around in your add-on to see what if anything has broken, investing some time getting mypy working is recommended, as it…

but I cannot find anything about importers. I have not found any similar documentation regarding changes in version 2.1.44 and 2.1.46.

I think this is the commit that caused this:

switch the Importers global to a callable for i18n

I guess you can work around the issue for now by monkey-patching the new importers() function.
