addon repository

[crpb]

Yeah setting up a repository is still on my list. I have to find a convenient way for me to automate that, as it's quite some work to do it manually :)

I just thought it might be a good idea to open this issues to collect ideas/knowledge.

Well, i don't know how myself but that should probably be possible with some github actions-fu i guess. In which i'm no expert either, i have to add, but i have at least confidence in my shell-fu so i think i could at least put in a bit of time testing that thing.

First thought would be that it should not only include a "Release Based" repo but also one which will just be built for the latest commits on each branch. Don't know if that is even possible with the usually seen Version-Bumps in Kodi 🤔...

Some notes

• the version attribute shouldn't have leading zeroes and only consist of major.minor.patch[-beta*]

  date +%Y.%-m.%-d seems to work fine with create_repository.py

• action-kodi-addon-checker
