As of this discord conversation, it was found out that metatools doesn't have functionality for fetching a commit from github: https://discord.com/channels/629035601613684748/698600499280347166/1010987512036069497

Here is a proposed way the yaml could look like:

pkgname:
  generator: github-1
  packages:
    - pkgname:
        github:
          user: pkgnamedev
          repo: pkgnamerepo
          query: commit
          branch: master

Additionally a good idea would be to be able to filter commit messages as sometimes I have seen developers that commit with a certain naming convention to label broken and working commits.

Package versions can be named using the date the commit was made on.

As of right now I know of 2 packages(because I contributed them) that use a full autogen to do this sort of stuff, rtl8812au and rtl8192eu so they can be used as an example implementation
