Inspiration

• flake.nix grew from https://github.com/colemickens/nixos-flake-example/blob/master/flake.nix
• overlays/paperwm/flake.nix is based off https://github.com/nix-community/neovim-nightly-overlay/blob/master/flake.nix

Setup

NixOS

Add to /etc/nixos/configuration.nix:

{
  nix.extraOptions = ''
    experimental-features = nix-command flakes
  '';
  nix.binaryCaches = [ "https://enzime.cachix.org" ];
  nix.binaryCachePublicKeys = [
    "enzime.cachix.org-1:RvUdpEy6SEXlqvKYOVHpn5lNsJRsAZs6vVK1MFqJ9k4="
  ];
}

Non-NixOS

Add to ~/.config/nix/nix.conf:

experimental-features = nix-command flakes
substituters = https://enzime.cachix.org https://cache.nixos.org/
trusted-public-keys = enzime.cachix.org-1:RvUdpEy6SEXlqvKYOVHpn5lNsJRsAZs6vVK1MFqJ9k4= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=

Usage

nixos-rebuild build-vm --flake github:Enzime/dotfiles-nix#phi-nixos

home-manager switch --flake github:Enzime/dotfiles-nix#enzime@phi-nixos

Cachix w/o adding to config

If you did not add Cachix to your Nix config, you can use the following flags on any Nix commands:

--option substituters "https://enzime.cachix.org https://cache.nixos.org" --option trusted-public-keys "enzime.cachix.org-1:RvUdpEy6SEXlqvKYOVHpn5lNsJRsAZs6vVK1MFqJ9k4 cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY="
