Why is it that I can build this file but not eval it? I just wanna get the storePath during eval

  dinix ? import <dinix>,

Thanks! I think I can make it work with this 😄

lix module overlay without flakes question: i'm experimenting with removing flakes from my system but am running into an issue where some override accesses the lix.rev of the lix argument, which doesn't exist (i'm using npins, it's called .revision)

nixpkgs.overlays = [
  (import "${sources.lix-module}/overlay.nix" {
    lix = sources.lix // {
      # rev = sources.lix.revision;
    };
    versionSuffix = "-pre-${builtins.substring 0 12 sources.lix.revision}";
  })
];

in my configuration.nix gets me

error: attribute 'rev' missing
at /nix/store/bbl3a77bpxlqml9sqclz2ax2fqvgj1y3-source/overlay.nix:120:62:
   119|           __intentionallyOverridingVersion = true;
   120|           version = "2.94.0-lix-${builtins.substring 0 7 lix.rev}";
      |                                                              ^
   121|

(with my hacky fix for this commented out)

i had a similar problem a while back, iirc this is a known issue. the fix which i think raito recommended was:

((import "${pins.lix-module}/overlay.nix") { lix = { outPath = pins.lix; rev = "dirty"; }; })

what...?
