Nix

nix.shell

  • Declaratively define shell including packages
let
  nixpkgs = fetchTarball "https://github.com/NixOS/nixpkgs/tarball/nixos-23.11";
  pkgs = import nixpkgs { config = {}; overlays = []; };
in

pkgs.mkShell {
  packages = with pkgs; [
    git
    neovim
    nodejs
  ];
  
  GIT_EDITOR = "${pkgs.neovim}/bin/nvim";

  shellHook = ''
    git status
  ''
}
  • Run nix-shell in same folder as nix.shell
  • Packages defined in the packages attribute will be available in $PATH
  • Any attributes that aren’t special are used as env variables
