This is the my personal computer configuration repo. I manage my dot files here, plus installed packages and various settings.
The entrypoint is flake.nix which produces outputs with
configurations for Home Manager and for NixOS.
Home Manager can be used on NixOS, or on another system with the Nix package manager installed. I have the Home Manager config separate from the NixOS config. (It is possible to use Home Manager as a NixOS module instead.) But because they are set up through the same flake both configs are locked to the same nixpkgs revision, and share the same overlays.
The layout is based on the standard template from Nix Starter Config.
The flake includes a devshell for bootstrapping Home Manager. As long as Nix is installed the devshell can be run like this:
$ NIX_CONFIG="experimental-features = nix-command flakes" nix develop
Then from the devshell run the switch commands below.
To install the NixOS config,
$ sudo nixos-rebuild switch --flake ~/Documents/NixConfig
To install the Home Manager config,
$ home-manager switch --flake ~/Documents/NixConfig
My very first reusable Home Manager module adds an option to set a list of Gnome extension UUIDs, and it automatically installs the necessary packages, and enables those extensions. Check it out in modules/home-manager/gnome-extensions.nix. You can see it in use in my Gnome configuration module, home-manager/features/gnome/default.nix.
