** Nix & NixOS
* [[[https://nix.dev/][Nix](https://nix.dev/][Nix)]] is used to define packages, environments, and configuration as pure expressions.
* [[[https://nixos.org/][NixOS](https://nixos.org/][NixOS)]] evaluates Nix expressions into a complete system configuration that can be applied by rebuild operations.
** Repository layout and folder conventions
This repository contains system modules, user modules, and configuration fragments. The following directories are treated as separate layers:
./configuration (NixOS modules), ./home (Home Manager modules), and ./assets/conf (configuration fragments referenced or deployed by the modules).
To keep navigation consistent, the same internal substructure is used in all three locations. Each layer keeps its role; only the internal grouping is standardized.
** Shared domain folders
core/ – base settings and common infrastructuredesktop/ – graphical session, compositor, UI components, and integrationapps/ – application enablement and application-level configurationservices/ – background services and daemonssecurity/ – secrets handling and security-related configurationdev/ – developer tooling and editor configuration
** Full tree (including unchanged parts)
The tree below shows the full repository layout, with the standardized internal structure applied only inside

- Only the internal layout of
configuration/, home/, and assets/conf/ is standardized; all other paths remain as currently organized.
- The
services/ and security/ folders are included for completeness even if initially empty in some layers.
~YourNixCode(Input) -> System Configuration~
I use [[https://nixos.wiki/wiki/Flakes][nix flakes]] which means that the entry point for the nix evaluation is a file called ~flake.nix~ which has two parts (among other things)
#+begin_src nix
{
inputs: # describes the function input, consisting mainly of package sources
outputs: # what the function outputs, a nixos configuration in our case
}
#+end_src
Nix flakes is still behind an ~experimental~ flag, but it is de facto the standard by most of the community.
Flakes allow us to pin the input package versions using a ~flake.lock~ file.
This prevents unwanted and surprise updates when rebuilding without changing the configuration.

* Configuration Variables
I have a bunch of constant strings that I would rather put in a file. Thats what ~user.nix~ is.
The values are imported at the beginning and are available to almost all the functions being called to configure the system.
#+begin_src nix :tangle user.nix
{
system = "x86_64-linux";
username = "henrov";
stateVersion = "25.11";
locale = "nl_NL.UTF-8";
}
#+end_src
* Flake Inputs
The inputs for my system's configuration are very simple
1. [[https://search.nixos.org/packages][nixpkgs]] - the main nix repository of packages. Its huge and growing. Pinned to the unstable release channel.
Sometimes pinned to a specific commit because unstable broke something and the fix hasn't made it into the release yet.
2. [[https://nix-community.github.io/home-manager/][home-manager]] - a nix module that helps keep track of user specific dotfiles and configurations as part of my nix config.
3. [[https://github.com/nix-community/emacs-overlay][emacs-overlay]] - this has more configuration options and generally a newer emacs available provided by the community.
4. [[https://nix.catppuccin.com/][catppuccin]] - nix module that allows everything to be catppuccin themed.
#+begin_src nix :tangle flake.nix :noweb tangle
{
description = "Henrov's nixos configuration";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
home-manager = {
url = "github:nix-community/home-manager";
inputs.nixpkgs.follows = "nixpkgs";
};
emacs-overlay = {
url = "github:nix-community/emacs-overlay";
inputs.nixpkgs.follows = "nixpkgs";
};
catppuccin = {
url = "github:catppuccin/nix";
inputs.nixpkgs.follows = "nixpkgs";
};
zen-browser = {
url = "github:youwen5/zen-browser-flake";
inputs.nixpkgs.follows = "nixpkgs";
};
};
<>
}
#+end_src
* Flake Output
Now that the inputs are ready, the outputs define what the system will actually look like. I also define the machines that this configuration specifies early on. Finally, I iterate over the ~machines~ list and pull files from ~/.machines/${name}~ subdirectory. This allows me to have configuration that has machine specific configuration limited to those files while also keeping a modular reusable base.
We also add a devshell that makes editing this repository easier in emacs.
#+name: flake-outputs
#+begin_src nix :noweb no-export
outputs = inputs@{
nixpkgs,
home-manager,
emacs-overlay,
catppuccin,
...
}:
let
user = import ./user.nix;
lib = nixpkgs.lib;
machines = [
"traveldroid"
];
pkgs = import nixpkgs {
inherit (user) system;
};
in
{
nixosConfigurations = builtins.listToAttrs (
builtins.map (machine: {
name = machine;
value = lib.nixosSystem {
modules = [
<>
<>
<>
catppuccin.nixosModules.catppuccin # theme
];
specialArgs = {
hostname = machine;
inherit user;
inherit inputs;
flakeRoot = inputs.self;
};
};
}) machines
);
devShells.${user.system}.default = pkgs.mkShell {
buildInputs = with pkgs; [
nil
nixfmt-rfc-style
];
};
};
#+end_src
Lets look at the individual modules
1. Emacs
The first is the emacs overlay so that it uses the nix-community emacs overlay from the inputs instead of the nixpkgs one.
Overlays are a special nix way to override existing packages within a repository.
#+name: flake-emacs-module
#+begin_src nix
({ ... }: {
nixpkgs.overlays = [ emacs-overlay.overlays.default ];
})
#+end_src
2. Then the machine specific configuration, in this case, just "traveldroid".
#+name: flake-config-module
#+begin_src nix
./machines/${machine}/configuration.nix
#+end_src
3. And finally the home-manager module.
This can be initialized and managed on its own but I'd rather use the ~nixos-rebuild~ command to build everything instead of managing userland dotfiles separately.
#+name: flake-home-module
#+begin_src nix :noweb no-export
home-manager.nixosModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.extraSpecialArgs = {
inherit user inputs;
flakeRoot = inputs.self;
};
<>
<>
}
#+end_src
- Home-Manager will not overwrite existing configuration files and that is good in most cases, but when everything is declarative like it is here, I'd rather that home-manager create a ~.backup~ and replace the file.
#+name: flake-home-backup
#+begin_src nix
home-manager.backupFileExtension = "backup";
#+end_src
- Finally I pull in the machine specific home configuration. Along with the overrides from catppuccin.
#+name: flake-home-config
#+begin_src nix
home-manager.users.${user.username} = {
imports = [
./machines/${machine}/home.nix
catppuccin.homeModules.catppuccin
];
};
#+end_src
** Envrc + Direnv
Editing this file will be much nicer if we have the dev environment configured.
That is done in the devshells section. But to auto load this dev shell, we need a .envrc file.
This tells [[https://direnv.net/][direnv]] to load the devshell in the flake.
#Finally, we also look for a .envrc-private file and try to load that. That contains devshell specific secrets.
#+begin_src nix :tangle .envrc
use flake
watch_file .envrc.private
if [[ -f .envrc.private ]]; then
source_env .envrc.private
fi
#+end_src
* Machines
The individual machines subdirectory is configured as follows :-
#+name: tree
#+begin_src ditaa
+--machine
| +--configuration.nix
| +--home.nix
| +--hardware-configuration.nix
#+end_src
- configuration.nix has the system configuration.
- home.nix has the user level configuration.
- hardware-configuration.nix has the unique hardware configuration.
- Note about imports
~imports = []~ in a nix file will pull in the function/object from the list of files provided.
This imported object (or function result) is just trivially merged into a common object.
We can take a look at that the common hardware options I have for all my machines.
*** Other Utils
**** Updates
To update the computer, I just need to update the ~flake.lock~ file to have references to the latest repository. This is done with :-
#+begin_src bash
nix flake update
#+end_src
* Hardware
I'll let the code comments explain the file here.
#+begin_src nix :tangle hardware/hardware.nix :noweb tangle :mkdirp yes
{ pkgs, lib, user, config, ...} :
{
nixpkgs.hostPlatform = lib.mkDefault user.system; # x86_64-linux
powerManagement.cpuFreqGovernor = lib.mkDefault "powersave"; # enable power saving on the cpu
# update cpu microcode with firmware that allows redistribution
hardware.cpu.intel.updateMicrocode = lib.mkDefault config.hardware.enableRedistributableFirmware;
hardware = {
# always enable bluetooth
bluetooth.enable = true;
# always enable graphics drivers and enable a bunch of layers for it (including vulkan validation)
graphics = {
enable = true;
extraPackages = with pkgs; [
vulkan-validation-layers # helps catch and debug vulkan crashes
];
};
};
hardware.enableAllFirmware = true; # enable all firmware regardless of license
}
#+end_src
* Configuration
This section describes the main system configuration for the computers that I have. Nix will look for a ~default.nix~ file if you give it a path to a folder to import. And ~default.nix~ looks as follows :-
#+begin_src nix :tangle configuration/default.nix :noweb tangle :mkdirp yes
{ pkgs, user, ... } :
{
imports = [
./apps/install_flatpaks.nix
./apps/install_packages.nix

./core/networking.nix
./core/nix-settings.nix
#./core/login-tuigreeter.nix

catppuccin.enable = true;
catppuccin.flavor = "mocha";
catppuccin.accent = "blue";
system.stateVersion = user.stateVersion;
}
#+end_src
** Apps section
This section describes a way of installing packages, either through nixpkgs orr flatpak. What apps to instal is decided in the files ./assets/conf/apps/packages.conf and flatpaks.conf
** install_packages.nix
#+begin_src nix :tangle configuration/apps/install_packages.nix :noweb tangle :mkdirp yes

** Ollama
This Home Manager Nix module (ai.nix) installs the Ollama package and configures it by reading a simple key-value configuration file (ollama.conf) for settings like the server host and default model. It sets environment variables (OLLAMA_HOST and OLAMA_DEFAULT_MODEL) for easy access in your shell or applications, with fallback defaults if the config file is missing or empty. Optionally, it also defines a user-level systemd service to automatically start the Ollama server on NixOS or systems with Home Manager’s systemd support enabled.

** Rotating Wallpaper
rotating_wallpaper.nix installs wpaperd and deploys your wallpaper files from the repo (./assets/conf/desktop/wallpaper/pictures/) into ~/conf/desktop/wallpaper/pictures. It also deploys the default wallpaper configuration from assets/conf/desktop/wallpaper/wallpaper.conf into ~/conf/desktop/wallpaper/wallpaper.conf, which is the file you can edit as a user override.
Finally, it creates a systemd user service (wpaperd.service) that automatically starts wpaperd at login and keeps it running, using your override config so wallpapers rotate according to your settings.

** hyprscrolling
This Nix module integrates the hyprscrolling plugin into a Home-Manager managed Hyprland setup in a declarative and reproducible way. It ensures the plugin is installed, optionally switches Hyprland to the scrolling layout, and renders user-defined plugin settings directly into the Hyprland configuration. The goal is to manage the scrolling workspace behavior entirely from Nix instead of maintaining manual edits inside hyprland.conf.
