使用 home-manager 管理用户配置

安装

1. 添加对应 channel

 nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
 nix-channel --update

如果用的是稳定版 Nixpkgs， 需要把 channel 换到对应分支， 比如 22.05 对应 https://github.com/nix-community/home-manager/archive/release-22.05.tar.gz

 nix-shell '<home-manager>' -A install

{ config, pkgs, ... }:

{
  # Home Manager needs a bit of information about you and the
  # paths it should manage.
  home.username = "rewine";
  home.homeDirectory = "/home/rewine";

  # This value determines the Home Manager release that your
  # configuration is compatible with. This helps avoid breakage
  # when a new Home Manager release introduces backwards
  # incompatible changes.
  #
  # You can update Home Manager without changing this value. See
  # the Home Manager release notes for a list of state version
  # changes in each release.
  home.stateVersion = "22.11";

  # Let Home Manager install and manage itself.
  programs.home-manager.enable = true;

  programs.emacs = {
    enable = true;
    extraPackages = epkgs: [
      epkgs.nix-mode
      epkgs.magit
    ];
  };

  services.gpg-agent = {
    enable = true;
    defaultCacheTtl = 1800;
    enableSshSupport = true;
  };
}

使用 flake

{
  description = "Home Manager configuration of Jane Doe";

  inputs = {
    # Specify the source of Home Manager and Nixpkgs.
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, home-manager, ... }:
    let
      system = "x86_64-linux";
      pkgs = nixpkgs.legacyPackages.${system};
    in {
      homeConfigurations.rewine = home-manager.lib.homeManagerConfiguration {
        inherit pkgs;

        # Specify your home configuration modules here, for example,
        # the path to your home.nix.
        modules = [
          ./home.nix
        ];

        # Optionally use extraSpecialArgs
        # to pass through arguments to home.nix
      };
    };
}
