NixOS Config Builder

A Rust iced GUI application for browsing NixOS options and generating configuration.

Features

• Browse NixOS options by category tree
• Search options by name or description
• Generate configuration.nix from selected options
• Full NixOS module coverage via nixosOptionsDoc

Requirements

• Rust 1.70+
• NixOS (for generating options.json)

Getting Started

1. Generate options.json

# Using nix
nix run github:NixOS/nixpkgs/nixos-unstable -- \
  --expr 'let pkgs = import <nixpkgs> { system = "x86_64-linux"; }; in pkgs.nixosOptionsDoc { options = (pkgs.lib.evalModules { system = "x86_64-linux"; modules = [ (import <nixpkgs/nixos/modules/lib/eval-modules.nix { modules = import <nixpkgs/nixos/modules/module-list.nix;> }) ]; }).config; }'

2. Build and Run

cargo build --release
./target/release/nixos-config-builder

Architecture

The application follows a clean 4-layer architecture:

src/
├── app/          # Application state and messages
├── config/       # Config generation (pure functions)
├── data/         # Schema types and JSON loading
├── search/       # Trie-based search
└── ui/           # iced GUI components
