Make darwin/home/nixosModules not be set when no modules are present

[JumpIn-Git]

Right now, if you use blueprint in a flake, the outputs darwin/home/nixosModules will be set to a empty attribute if there are no modules, this can be easily fixed with lib.mkIf. This error also exists with darwin/system/nixosConfigurations, and using lib.mkIf will make those lines quite long, I don't have a solution for that currently.

Any idea's on the latter are welcome!

Why do the check's complain about uncommited changes, I had that too...

What does nixosConfigurations = lib.mapAttrs (_: x: x.value) (hostsByCategory.nixosConfigurations or { }); do? Why is the mapAttrs needed? I would like to usee a helper function to shorten it:

  # If arr = modules 
  # and args = {nixosModules = "nixos"}
  # it should eval to
  # [(
  #   lib.mkIf (arr ? "nixos") {nixosModules = modules.nixos;}
  # )];
  mapTo = arr: {...} @ args:
    lib.mkMerge (
      let
        names = lib.attrNames args;
      in
        builtins.map (n: let
          v = args.${n};
        in
          lib.mkIf (
            arr ? ${v}
          ) # If args = {nixosModules = "nixos";}, check arr.nixos exists
          
          {${n} = arr.${v};})
        names
    );

(needs testing)

It's tricky to have the top-level attrset be composed like that. The last time I tried, I hit infinite recursion issues. Probably because it makes the attrset less lazy.

To solve this, probably the solution is to move from a model where blueprint is the flake output, to one where blueprint generates and instance, that then gets converted to a flake output. And then have all the references to "flake" or "self" point to the blueprint instance. The flake output is then a conversion that takes the blueprint and converts is to a "clean" flake output.

I thought my solution worked, but is doesnt... this is way more complicated then I thought

Closing, as I cant find a solution, made a issue: #92
