This repository is a personal Nix configuration (dotfiles) for managing a heterogeneous fleet of machines: NixOS desktops and servers, macOS laptops (via nix-darwin), and Kubernetes clusters (k3s, KubeVirt). It is structured as a Nix flake with modular components for system configuration, home-manager profiles, package overlays, secrets management (agenix), and infrastructure monitoring (Grafana, Prometheus, VictoriaMetrics, Loki). The codebase demonstrates advanced Nix patterns: parameterized module generators for K3s and KubeVirt, automatic file scanning for module imports, declarative disk partitioning (disko), ephemeral root filesystems with persistent state (preservation), and sandboxed GUI applications (nixpak, bwrap). It also includes a custom desktop shell (noctalia) and extensive input method customization (Rime/Fcitx5). While highly personalized and not intended for direct reuse, the architectural patterns and modular design serve as a reference for building complex Nix-based infrastructure. The repository is actively maintained with eval tests and CI, but lacks integration tests for runtime services.
This is a personal dotfiles repository for NixOS, authored by Henrik Lissner (hlissner). It serves as a complete, declarative system configuration for multiple machines (laptops, desktops, and a HTPC) using Nix flakes. The repository defines the entire system—from the bootloader and kernel parameters to the desktop environment (Hyprland), shell (zsh, tmux), development tools, and custom utilities. It is not a standalone application but a collection of configuration files, NixOS modules, and scripts that together form a highly opinionated, reproducible computing environment. The architecture is centered around a Nix flake (flake.nix) that imports modular NixOS modules organized by category (desktop, development, editors, shell, services, hardware profiles, themes, etc.). A custom CLI tool called 'hey' (written in Janet) provides a command hub for system management tasks like rebuilding, garbage collection, profile switching, and dotfile synchronization. The desktop environment is heavily customized with Hyprland (Wayland compositor), rofi launcher menus, matugen-based dynamic theming, and a suite of utility scripts for screenshots, screen recording, audio, and more. While the repository is not designed for reuse by others (it explicitly warns against being used as a community framework), several components demonstrate high craftsmanship and could be extracted with minimal modification. The Janet libraries under lib/hey/ provide a reusable command-line argument parser, an async rofi interaction library, and general utility functions. The Nix library (lib/nixos.nix) implements a flake builder pattern that could be adapted for other multi-host NixOS setups. The matugen templates and rofi themes are also potentially reusable as standalone theming assets.
