i had to change the EDIT:
i just realized that this won't work because every new commit will result in a new sha256 sum, breaking this pkg as a result. |

@crutonjohn can you take a look at the changes I suggested? I'd be happy to take over the PR if you'd like too. |
these all look good to me, I've been on holiday with my family but happy to take care of this sometime this week. |
awesome, looking forward to getting rid of this from all my shell.nix/flake.nix files :D |

I think we should use the finalAttrs pattern here.
The finalAttrs pattern will let you remove the rec keyword (see its implementation in Nix).
Why is this pattern preferred to rec ?
Let's take this simple code example:
mkDerivation rec {
foo = 1;
bar = foo + 1;
}and then .overrideAttrs(old: { foo = 2; }), you'll get { foo = 2; bar = 2; } while with finalAttrs pattern, it would work correctly because it's a real fixed point.
Let me share a couple of useful links regarding the finalAttrs pattern:
- History: https://discourse.nixos.org/t/avoid-rec-expresions-in-nixpkgs/8293
- Documentation: https://nixos.org/manual/nixpkgs/unstable/#mkderivation-recursive-attributes
- Recent example of implementation: https://github.com/NixOS/nixpkgs/compare/17f96f7b978e61576cfe16136eb418f74fab9952..9e6ea843e473d34d4f379b8b0d8ef0425a06defe
Feel free to reach out if you need some assistance.

If I get rid of repo = pname then I don't need rec at all, nor finalAttrs, 2 birds with one stone!

Please don't use this.
repo = pname; is nice for DRY but creates a binding that goes too far.
