Hope you're not sick of me yet... ;)

Somewhat unfortunate that meta points to pkgs/stdenv/generic/make-derivation.nix for the rare cases (if any) where a package doesn't have a description, but what can ya do...

Yeah I thought about what meta attribute is set for almost all packages. If there is a better way to find the file containing the meta section for a nixpkgs attribute, it would be great to know it.
Otherwise we can try to improve the checks to detect if it found the wrong file, for example a specific check for make-derivation.nix.

I committed something similar to your suggested change, but I will still leave this conversation open, because I think there should be more improvements in this regard.

There is <pkg>.meta.position, but that doesn't work for things like cargo-download which returns pkgs/build-support/rust/build-rust-crate/default.nix:224 (and includes the line number, which would need to be stripped out).

Something to keep in mind with your new wording here: trying to evaluate builtins.unsafeGetAttrPos \"meta.description\" claws (as displayed) returns null, while builtins.unsafeGetAttrPos \"description\" claws.meta (which is what is actually evaluated) returns the desired information.

Works for me, and that would probably be just enough for me 😄 |

Thank you @petabyteboy ✨ |
