Homini

Homini is a minimalist dotfiles manager using Nix inspired by Home Manager and GNU Stow.

How to use Homini?

Consider the following snipet

homini = {
  enable = true;
  dir = ./dotfiles;
};

this will link the dotfiles directory

dotfiles
└── .config
    └── git
        ├── config
        ├── ignore
        ├── personal
        └── work

to your $HOME directory.

$HOME
└── .config
    └── git
        ├── config -> /nix/store/xqj0sf5q4q35q1hp19yyhfp8sbp0zrwa-dotfiles/.config/git/config
        ├── ignore -> /nix/store/xqj0sf5q4q35q1hp19yyhfp8sbp0zrwa-dotfiles/.config/git/ignore
        ├── personal -> /nix/store/xqj0sf5q4q35q1hp19yyhfp8sbp0zrwa-dotfiles/.config/git/personal
        └── work -> /nix/store/xqj0sf5q4q35q1hp19yyhfp8sbp0zrwa-dotfiles/.config/git/work

NixOS

Rebuild the following flake with nixos-rebuild switch --flake .#machine.

{
  description = "My NixOS Configurations";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    homini.url = "github:minizilla/homini";
    homini.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { nixpkgs, homini, ... }: {
    nixosConfigurations.machine = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ./configuration.nix
        homini.nixosModules.homini {
          homini = {
            enable = true;
            dir = ./dotfiles;
          };
        }
      ];
    };
  };
}

MacOS (nix-darwin)

Rebuild the following flake with darwin-rebuild switch --flake .#machine.

{
  description = "My MacOS (nix-darwin) Configurations";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    darwin.url = "github:LnL7/nix-darwin";
    darwin.inputs.nixpkgs.follows = "nixpkgs";
    homini.url = "github:minizilla/homini";
    homini.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { darwin, homini, ... }: {
    darwinConfigurations.machine = darwin.lib.darwinSystem {
      system = "x86_64-linux";
      modules = [
        ./configuration.nix
        homini.darwinModules.homini {
          homini = {
            enable = true;
            dir = ./dotfiles;
          };
        }
      ];
    };
  };
}

Standalone

Run the following flake with nix run.

{
  description = "My dotfiles";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    homini.url = "github:minizilla/homini";
    homini.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { nixpkgs, homini, ... }:
    let
      forAllSystems = nixpkgs.lib.genAttrs nixpkgs.lib.systems.flakeExposed;
    in
    {
      packages = forAllSystems (system: {
        default = homini.standalone {
          pkgs = nixpkgs.legacyPackages.${system};
          dir = ./dotfiles;
        };
      });
    };
}

Why Homini when we have Home Manager?

This Article by Florian Beeres is what inspired me to write Homini and this quote sums up why

At the end of the day I really don’t need the per-user installation of packages and elaborate modules that Home Manager gives me. I’d be perfectly content with providing a list of packages to install system-wide and a few basic primitives to generate configuration files in my home folder.
