Installation

Use the provided flake input:

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";

    optnix.url = "github:water-sucks/optnix";
  };

  outputs = inputs: {
    nixosConfigurations.jdoe = inputs.nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ({pkgs, ...}: {
          environment.systemPackages = [
            inputs.optnix.packages.${pkgs.system}.optnix
          ];
        })
      ];
    };
  };
}

Or import it inside a Nix expression through fetchTarball:

{pkgs, ...}: let
  optnix-url = "https://github.com/water-sucks/optnix/archive/GITREVORBRANCHDEADBEEFDEADBEEF0000.tar.gz";
  optnix = (import "${builtins.fetchTarball optnix}").packages.${pkgs.system}.optnix;
in {
  environment.systemPackages = [
    optnix
    # ...
  ];
}

When will this be in nixpkgs/home-manager/nix-darwin/etc.?

I'm working on it.

Ideally I'll want to get the whole project into nix-community too, once it gains some popularity.

Cache

There is a Cachix cache available. Add the following to your Nix configuration to avoid lengthy rebuilds and fetching extra build-time dependencies:

{
  nix.settings = {
    substituters = [ "https://watersucks.cachix.org" ];
    trusted-public-keys = [
      "watersucks.cachix.org-1:6gadPC5R8iLWQ3EUtfu3GFrVY7X6I4Fwz/ihW25Jbv8="
    ];
  };
}

Or if using the Cachix CLI outside a NixOS environment:

$ cachix use watersucks

Extras

There are also some packaged Nix modules for easy usage that all function in the same manner, available at the following paths:

• nixosModules.optnix :: for NixOS systems
• darwinModules.optnix :: for nix-darwin systems
• homeModules.optnix :: for home-manager systems

Alongside these modules is a function mkLib; this function is the entry point for the optnix Nix library for generating lists.

More information on these resources can be found on the module page, as well as the API Reference for what functions are available in the optnix library.

Additionally, some examples configuring optnix for different module systems are available on the recipes page.
