Mentioned in #116

I think we could add a Github Actions to automize the version release. It could also work for other repos of api7 that need to upload to luarocks.

The process would be like, whenever we push a new tag, it would upload the new release on github and also upload rockspec to luarocks.

One thing to discuss is that, do we need to bind the release action to PR, say when we have a release PR tagged with "Release", when it got merged, the action would be triggered to create a tag, and do the rest.
It would be more convenient, but we need an extra PR when changing release larger change, say from 1.4.3 to 1.5. Ref: https://github.com/anothrNick/github-tag-action

TODO

• test on personal repo to make sure it works
• ask @membphis for upload luarocks token

@membphis PTAL

I think it works for now since I test it in my own repo and it works fine (see workflow in my repo)

Also plz make sure the token name in secrets is LUAROCKS_TOKEN

CI could be fixed with #120
