As per the title, users can use addlicense as a pre-commit hook:

# .pre-commit-config.yaml

repos:
  - repo: https://github.com/XuehaiPan/addlicense
    rev: '0a8669'
    hooks:
      - id: addlicense
        args: [-check, -l, apache, -c, "Some Team. All Rights Reserved."]

Think this can probably be merged right? Looks like everything is all set unless I am missing something

Looks like you need an approving reviewer.
@willnorris ?

@C-Loftus is there a meaningful difference between this and #138? Is the syntax in that pr still valid? I kinda like that one since it also adds docs.

@mco-gh : oh crap, am I the last person left with access? Well that's not good. You know, removing access when people left the company seemed to make sense at the time, but now I'm not so sure 😕 Do you know who's left that could take this over? I'm not really interested in maintaining long-term since I haven't used it in years

Hi @willnorris Yes, I lost access when I left Google in November. I don't know anyone else who would want to take this over so I think the ball is now in your court.

Yes #138 looks great to me. I tested that PR out at internetofwater/scheduler#89 and you can see it applies the license fine. pre-commit output shows all success in a pipeline of other hooks as well.

Would be great if we could merge one of these so it doesn't fall through the cracks. Should be just a one file change without adding any burden on maintainers and then a lot of similar issues/old PRs requesting pre-commit can be simultaneously closed up.

Closing in favor of #138 which is now merged
