Ping meta.maintainers

[FRidh]

We still need to ping maintainers of packages/modules in case their expressions are modified.

Proposal:

1. use nix-env to check which packages need to be rebuild
2. retrieve for each package meta.position
3. check if the file specified in 2) is in the diff. If so, ping the maintainers listed in somepkg.meta.maintainers.

The attributes are typically GitHub handles, but as far as I know there is no way in Nix to get that handle.

Two possible solutions to retrieve the handle:

1. rewrite lib.maintainers (@handle in lib/maintainers.nix must be a github username nixpkgs#18352 (comment))
2. use sed

Maintainers change in Nixpkgs: NixOS/nixpkgs#34842

I think there is also an option to have a separate table (in Nix or in CSV) of email-as-listed → github handle, full name, IRC nick…

Note the Nixpkgs change is in (NixOS/nixpkgs#36119)

I would love if someone implemented this for ofborg. https://github.com/ryantm/nix-update already uses the new github handles.

Step #3 seems particularly complicated... I wonder if @vcunat has had an opportunity to come up with a "root change" script?

[FRidh]

@grahamc what is complicated about step 3? meta.position includes a filename. Or do you mean "it would be nice if there was a simpler solution"?

[vcunat]

No, not yet.

Maybe label PRs about packages that miss maintainers, too? Got the idea after reading the discussion: NixOS/nixpkgs#54249

[dasJ]

Is this still relevant? Ofborg already pings maintainers if they are in the org

Thanks!
