What is this

A almost reproducible nix build for Emacs on MacOS

requirement

homebrew

homebrew is used to install fontconfig and font-symbols-only-nerd-font

pkg-emacs29.nix

this will compile emacs29 on mac using tyler-dodge's nix config so that nix-darwin can manage emacs instead of using homebrew. Read the post for more details.

However, the original nix file is for compiling author's fork of emacs, which he add optimization for enhancing EShell performance, and it is based on emacs 29.0.60.

this modified nix config change it to use pkgs.emacs29 source, which is emacs version 29.1 required by doom-emacs.

pkg-doom-emacs.nix

this will install dependencies for doom-emacs

  • pkgs.coreutils, copy GNU ls as gls
  • pkgs.pandoc, for :lang markdown Markdown processing
  • pkgs.shellcheck, for :lang sh Shell script linting

and install doom-emacs to ~/.config/emacs if ~/.config/doom does not exist.

config-doom-emacs.nix

Optionally you can add ./config-doom-emacs.nix to symbol link your doom-emacs config files to

  • $HOME/projects/mac-dev-setup/doom-emacs-init.el
  • $HOME/projects/mac-dev-setup/doom-emacs-packages.el
  • $HOME/projects/mac-dev-setup/doom-emacs-config.el

modify it to your need.

Usage Example

If you are using home-manager, in your home.nix file

{ config, pkgs, ... }:
let
  my-emacs29 = import ./pkgs-emacs29.nix { inherit pkgs; };
  my-doom-emacs = import ./pkgs-doom-emacs.nix { inherit pkgs; };
in {
  home.packages = with pkgs; [
    my-emacs29.emacs29
    my-doom-emacs
  ];

  # optional
  imports = [ ./config-doom-emacs.nix ];

}

or if you are not using home-manager, to install emacs system-wide, in your configuration.nix

{ config, pkgs, ... }:
{
  environment.systemPackages = [
    my-emacs29.emacs29
    my-doom-emacs
  ]
}
