NOTE: Nix home-manager 基本設定

home-manager 會讀取 .config/nixpkgs/home.nix 並套用裡面的設定（config），所以我們可以用一個 git repository 管理並用

ln -s $(pwd)/home.nix ${HOME}/.config/nixpkgs/home.nix

把設定掛到 home-manager 讀取的位置。一個基本的設定檔內容如下：

{ config, pkgs, ... }:
{
  programs.home-manager.enable = true;
  home.username = "$username";
  home.homeDirectory = "/home/$username";

  home.stateVersion = "21.03";

  home.packages = with pkgs;
    [
      // 你想安裝的套件，以下為示範
      tig
      curl
      silver-searcher
    ];
}

當然，不是任意字串都可以寫進去，套件是否存在可以到 nixos search packages 頁面裡搜尋確認。

某些常見的程式已經被寫死進 home-manager 中，因此可以得到更仔細的設定，如 zsh：

{ config, pkgs, ... }:
{
  // ...

  programs.zsh = {
    enable = true;
    enableAutosuggestions = true;
    enableCompletion = true;

    oh-my-zsh = {
      enable = true;
      plugins = [ "git" "dotenv" "osx" ];
      theme = "robbyrussell";
    };

    shellAliases = {
      ls = "ls -GFh";
      ll = "ls -l";
      la = "ll -a";
      vi = "nvim";
      vim = "nvim";
    };
  }

  // ...
}

還可以用 home.file."$filename".text 控制 home 目錄下的檔案內容，例如 agda 就需要設定 ~/.agda/defaults 跟 ~/.agda/libraries，如下：

{ config, pkgs, ... }:
{
  // ...
  home.file.".agda/libraries".text = builtins.readFile ./agda/libraries;
  home.file.".agda/defaults".text = builtins.readFile ./agda/defaults;
  // ...
}

builtins.readFile 後面接的檔案位置是相對於當前 home.nix 的位置。
