Could you add yourself as a maintainer of this package for the Darwin part?

Thanks @pshirshov! Since I plan on maintaining the search portion of the firefox home-manager module, you can add me as a darwin maintainer if you don't want to maintain it yourself.

(I have a x86_64-darwin mac to test on)

Oh, sorry, I missed that! 😓 - I'm too used to people force-pushing their changes. I should be more careful.

[pshirshov]

I think that squash on merge should be enabled for the repo.

[kira-bruneau]

@pshirshov I don't think we'd want to enable that, because in certain cases it makes sense to have multiple commits in one PR, and we don't want to lose that context.

The normal workflow in nixpkgs is to cleanup your history locally where it makes sense (eg. amend commits instead of adding "fixup" commits) and then force push your changes.

Yeah, but it's really convenient not to have local copy when I do some small changes in a nix formula. Also it's possible to allow squashes together with other policies.
