nix flake show fails
This is nothing important, i just wanted to tell yall about it, when i try to learn a flake i always run the nix flake show to see what is outputted in that flake. (everybody does things differently and trying to read nix code is hard ok????😭🥀)
$ nix flake show github:isabelroses/dotfiles

But i cloned the repository, entered nix develop environment and tried the nix flake show again and it worked and now it works even outside the repository.
To consistently get the error:
$ docker run --rm nixos/nix nix --extra-experimental-features "nix-command flakes" flake show github:isabelroses/dotfiles
If this flake meant to only be evaluated by lix lemme know, i will close the issue.
Thank you for the awesome code.
No errors:
$ docker run --rm ghcr.io/lix-project/lix:latest nix --extra-experimental-features "nix-command flakes" flake show github:isabelroses/dotfiles
Also no errors:
$ docker run --rm osbm/nix nix run nixpkgs#lix -- flake show github:isabelroses/dotfiles
Sorry for the stupid ahh docker commands i cant gc my store rn 🪫🥀
Judging by the leaky __final is that nixos/nix? If so it might be the differing lockfile format between lix and nix.
Yes, ill update my comment to nixos/nix
I might fix this. But honestly, I'm not inclined to because I would either have to call the package though npins or some other source and I don't think its worth the effort of vendoring.
I may expose my lix-patches though another flake if i ever get round to it. Which would also fix this.
Like i said this is nothing important. You really dont have to fix it if you don't want, this issue is meant to just inform you. Its totally up to you.
Should be fixed now :D
