personal dotfiles

Mostly declarative configuration for my computers, using Nix & flakes Currently serves 2 work machines:

• chunky-notebook : NixOS + home-manager
• work-laptop : home-manager on top of Ubuntu

Most treasured goodies:

• Emacs : with native-comp & pgtk, courtesy of “nix-community/emacs-overlay” with Doom Emacs config that’s being setup manually
• xmonad : comfortable tiling wm, for which I copy-pasted configs with xmobar, autorandr setup for monitor detection
• ability to reuse configuration between Ubuntu+Nix and NixOS I’d like it to have less technical debt & better documentation, but it works

installation

install basic nixos to the machine

enable flakes

in `config.nix` add

nix = {
  package = pkgs.nixUnstable;
  extraOptions = ''
    experimental-features = nix-command flakes
  '';
};

and apply the config

pull in repo (or possibly nix can install flake by github address too)

and apply config with

sudo nixos-rebuild switch --flake ~/dotfiles/.#chunky-notebook

Any “home-manager” related updates are also done with that command

NOTE cachix setup is not yet declarative

so on first installation either:

• use `nix shell nixpkgs#cachix; cachix use nix-community` to enable cache for “emacsPgtkGcc”
• disable “emacsPgtkGcc” for first installation and then add `nix-community` cache

notes on structure

Profiles :: Granular application/service configurations

(expected to be imported on `home-manager.users.<user>` level, if in future would want OS level modules would need to figure out anew) Read in the flake.nix, passed with inputs.self.nixosProfiles Could contain NixOS configuration & options as well as Home-Manager configuraitons, options & xdg files

Idea is to keep relevant nix configuration close to managed dotfiles and join configurations for applications that are managed in tandem

Intended for grouping in the Roles, so that Roles could be imported for machines

Modules :: defining options

(expected to be imported on `home-manager.users.<user>` level, if in future would want OS level modules would need to figure out anew) Option - is a value that can be set differently and which influences some part of configuration

My own modules are:

• autorandr sharing window configuration, by individual computer defining monitor fingerprints
• screenlocker setting different ‘lock’ command, to share code between NixOS & Ubuntu installed ‘xscreensaver’

Roles :: High level bundles of configuration

(doesn’t work yet - only Home-Manager common file there) Planned to combine lot’s of applications and settings so that machines would only need to specify their roles, and limited amount of profiles

todo

• make `cachix add nix-community` declarative
• !! `cachix add nix-community` is manual for now
• Manage the personal server with NixOS too
