Introduction   intro

What is Droidnix

Droidnix is a modular, declarative NixOS + Home Manager configuration system. It allows users to choose between Hyprland and Mangowc as their window manager, with shared and WM-specific configurations managed via Emacs Org and Nix Flakes. The project is designed for reproducibility, maintainability, and cross-machine compatibility.

Installed components:

Core
Hyprland
Mangowc

Goals, project Structure, import hierarchy

This project uses a modular NixOS configuration with Hyprland and MangoWC support, designed for literate programming and cross-device reusability. The Droidnix repository is organized into two main parts:

  1. .assets/: Static, non-generated files (e.g., configs, scripts, themes).
  2. Generated folders (system, hyprland, mangowc): NixOS and Home Manager configurations, generated from Org files.

Root Level

  • flake.nix is the entry point and imports:

    • generated/assets/
    • generated/<host>/modules/
    • generated/hosts/

Generated Structure

The generated/ directory contains all generated configurations, divided into three main groups: system, hyprland, and mangowc.

First Setup

  1. Clone this repository.
  2. Run the setup script: ./setup_droid.
  3. Edit .assets/traveldroid/conf/base.conf to choose your window manager (wm = "hyprland" or wm = "mangowc").
  4. Tangle this Org file to generate Nix configurations: C-c C-v t in Emacs or use this: emacs README.org --batch -f org-babel-tangle && emacs --batch --eval "(setq org-html-htmlize-output-type nil)" README.org -f org-html-export-to-html
  5. Build and switch: sudo nixos-rebuild switch --flake .#<hostname>.

The Assets Folder   assets

The .assets/ folder contains all static files, such as configs, scripts, and themes. These files are not generated and can be edited directly.

The Actual Code   code

This section contains the Org blocks for tangling Nix code into the generated folders.

flake.nix

The Nix flake definition for Droidnix.
