🔖 Feature description

Hey!
Im still not fully comfortable with nix, so excuse my ignorance, but is I have a standalone flake on Github, that i would like to use permanently inside of my system (preferably through home-manager). Is it possible to add it as some input into the home-manager?

Currently i have to run the "nix run" command to use my editor, and it would be nice to not have to maintain two configurations (one local and one flake)

I didn't find any better place for asking the question. Sorry.

Hi, instructions on how to consume a standalone package is detailed in the relevant section of the manual. If you have any specific questions, I can try to answer them but it boils down to (1) exposing the package and (2) consuming it from your flake via self.packages.${pkgs.system}.<package> inside home.packages or environment.systemPackages.

Thanks!
The way im understanding the manual is that the user defines the config at the same place as the home configuration. I would rather have the flake seperate from my system config, and then add the flake as a input into my config.

customNeovim.neovim in the manual uses nvf.lib.neovimConfiguration, so im unsure how to reproduce this step from a standalone flake inside of my system config flake.

Im sorry if my explanation of what I want isn't the clearest.

You can acquire the package from another flake as long as said flake exposes your wrapped neovim configuraton as a package that you can consume.

That would mean flake A, using nvf, builds your neovim setup and exposes it under, lets say, packages.x86_64-linux.neovim and then you can add flake A to flake B's inputs and get it as inputs.flakeA.packages....>

I cannot provide a complete example right now, but I'll see if I my network allows a git push tomorrow if you are still stuck.

Thanks a ton! I will try to get it to work today (and post if I manage to solve it).
If not, getting a example would be super appreciated.

I've managed to get it to work (atleast on my laptop)! I will post my solution here, please let me know if the way I've done it is suboptimal:

   inputs = {
    my-nvf.url = "github:nocxium/nvf";
  };

  outputs = { nixpkgs, ... }@inputs:
    let 
        my-nvf = inputs.my-nvf.packages;
    in {
      homeConfigurations = {
        "user@name" = home-manager.lib.homeManagerConfiguration {
          pkgs = nixpkgs.legacyPackages.x86_64-linux;
          extraSpecialArgs = { inherit inputs; };
          modules = [
          ./home-manager/configuration/home.nix
          {home.packages = [my-nvf.${system}.default];}
          ];
        };
      };
    };

Ive left the system out from my-nvf since i have arm machines as well.

Thanks once again

Edit: After taking a closer look, i see how much i had overcomplicated the inputs lol. I just added this to my home.nix and it works:

inputs.my-nvf.packages.x86_64-linux.default
