Flakes support?

[Qubasa]

Hi there,

I wanted to ask if there are plans to adopt flakes support?
That would be really awesome!

Cheers

nix flakes definitely seem like a nice idea and would fit well. I know @dguibert has done some work on this with #8, though I haven't looked too closely at it yet. I was sort of waiting until they became less experimental (specifically made it into a stable nix release on a stable nixpkgs release) before looking at switching over to them.

Hi,
@luis-hebendanz you could use my PR to test the flake support.
@dylex the flake support is pretty stable but still marked as experimental, you can view it as a declarative definition of NIX_PATH or channels.

@dguibert Awesome! I will try it out!

@dguibert How do I import that into a nixos flake configuration? I tried

inputs.nixpack.url = "github:dguibert/nixpack/dg/flake";

outputs = {self, nixpack}: {
        nixosConfigurations.my-desktop = nixpkgs.lib.nixosSystem {
            system = "x86_64-linux";
          ({ ... }: {
          nixpkgs.config = {
            allowUnfree = true;
            packageOverrides = pkgs:
            {
              nixpack = import (nixpack.packages)
              {
                system = "x86_64-linux";
              };
            }
           }
         }
     }
}

@dguibert How do I import that into a nixos flake configuration

Which issue do you face? See my PR description, the options --impure --option sandbox false are required.

To use it, I assume that into environment.systemPackages, you can put nixpack.pkgs.$package but this will use the basic nixosPack defined into the flake.

I see, try using nixpack = nixpack.packages.x86_64-linux;

@dguibert Thanks, that was it!
