My (very simple) Emacs config

I have been using Emacs for 15 years. In that time, I have had large configs, spacemacs, doom, evil/non-evil. This is my current configuration. Package installation is managed via a home-manager nix flake.

I am surprised that I was able to remove everything surrounding vertico and go with fido-mode easily.

I have a parallel configuration that removes lsp and uses eglot, but it's not as fleshed out. I need to be able to use both eslint and typescript language servers and I don't have a reliable way to do that in eglot.

I am currently using emacs-head. I know I don't need to use-package builtin emacs packages but I do anyway.

Yes, I use home-manager to manage my emacs packages, among other things. Here's the snippet that includes my emacs configuration. It's in a file called common.nix which I include in my base linux.nix and darwin,nix configurations.

There is a bit dynamism in the config that makes lsp or eglot or vertico configurations active. There is a bit at the bottom of my init.el that includes those files if they are present. It's not the cleanest solution, but it's mine.

{ pkgs, ... }:
let
  # myEmacs = if pkgs.stdenv.isDarwin then pkgs.emacsGit else pkgs.emacsPgtk;
  myEmacs = pkgs.emacsGit;
  useVertico = false;
  useLsp = true;
  emacsWithPackages = (pkgs.emacsPackagesFor myEmacs).emacsWithPackages;
in {
  home.packages = [
    pkgs.tree-sitter
    pkgs.nixfmt
    pkgs.ripgrep
    pkgs.bc
    pkgs.file
    pkgs.syncthing
    pkgs.streamlink
    pkgs.unzip
    (emacsWithPackages (epkgs:
      [
        (pkgs.callPackage ./copilot.nix {
          inherit (pkgs) fetchFromGitHub;
          inherit (epkgs) trivialBuild;
          inherit (epkgs.nongnuPackages) editorconfig;
          inherit (epkgs.melpaStablePackages) dash s;
        })
      ] ++ (with epkgs.elpaPackages; [ transient ])
      ++ (with epkgs.nongnuPackages; [ go-mode magit markdown-mode webpaste ])
      ++ (with epkgs.melpaStablePackages; [
        apheleia

deadgrep and treesit-auto seem really nice, added to my config!

donio

I like it.

Didn't know about apheleia, will have to check that one out.

Would you elaborate the part about home-manager? Do you use it to manage emacs packages?

Thanks for sharing. It is useful for us noobs to have a look at the configs of more experienced users.

Any thoughts on going from a more in depth, or involved config to a more simple one? I'm somewhere in between, I use vanilla emacs but my config file is pretty large. Most of the largeness comes from an entirely custom set of keybindings. I'm wondering if I should switch to something like xah fly keys instead and just learn new commands/bindings as i go instead of making new ones as I go.
