NixOS Configuration

This is my personal NixOS configuration using flakes, home-manager, and nixvim. It includes configurations for both regular NixOS and WSL (Windows Subsystem for Linux).

Features

• 🐧 NixOS: Complete system configuration with KDE Plasma desktop
• 🪟 WSL Support: NixOS running in Windows Subsystem for Linux
• 🏠 Home Manager: User environment and application configuration
• 🎨 NixVim: Neovim configuration with AI integration
• 🔐 Secrets Management: Both pass and SOPS for secure secret handling
• 🤖 AI Integration: OpenAI API integration for Neovim AI features

Quick Start

Prerequisites

1. Install NixOS (if not already installed)
2. Clone this repository to your system
3. Set up secrets (see Secrets Management section)
4. Enable your Cachix cache locally: cachix use arifinoid-nix

Building and Switching

# For regular NixOS
sudo nixos-rebuild switch --flake .#arifinoid

# For WSL
sudo nixos-rebuild switch --flake .#wsl-arifinoid

Development

# Update flake inputs
nix flake update

# Update specific input
nix flake update nixpkgs

# Build without switching
nix build .#arifinoid

Secrets Management

This configuration supports two secret management approaches:

1. Pass (Password Store)

• Setup: pass init <gpg-key-id>
• Add secret: pass insert arifinoid/openai.api.key
• Usage: cmd:pass show arifinoid/openai.api.key (in nixvim config)

2. SOPS (Secrets OPerationS)

• Setup: Run ./setup-sops-key.sh
• Edit secrets: sops secrets/secret.yaml
• Usage: Available as environment variables

AI Integration

The configuration includes AI-powered Neovim features:

• Avante: AI code assistant with multiple providers
• Claude Code: Claude AI integration
• OpenAI: GPT integration via pass or SOPS secrets

Key Bindings

• <leader>ca: Open AI Ask
• <leader>cc: Open AI Chat
• <leader>ce: Edit with instruction
• ta: Toggle Avante

System Configurations

arifinoid (Main NixOS)

• KDE Plasma desktop environment
• Full development environment
• Steam gaming support
• Bluetooth and audio configuration

wsl-arifinoid (WSL)

• Minimal WSL-optimized configuration
• Development tools and fonts
• SSH server support
• Cross-platform compatibility

Customization

Adding Packages

Edit the appropriate configuration file:

• System packages: nix/configurations/nixos/arifinoid.nix
• User packages: nix/modules/home/platform.nix

Neovim Configuration

• Main config: nix/nixvim/config/default.nix
• AI features: nix/nixvim/config/ai.nix
• Editor settings: nix/nixvim/config/editor.nix

Troubleshooting

Common Issues

1. SOPS decryption errors: Run ./setup-sops-key.sh and re-encrypt secrets
2. Plugin not found: Check if plugin exists in nixpkgs unstable
3. Build failures: Check flake inputs and dependencies

Getting Help

• Check NixOS manual: nixos-help
• Search packages: nix search <package-name>
• Check flake inputs: nix flake show

Inspiration

This configuration was inspired by these excellent NixOS setups:

• malob/nixpkgs - A comprehensive Nix configuration with flakes, home-manager, and nix-darwin support.
• r17x/universe - A development universe. Includes AI integration, secrets management with SOPS, and modern development tooling.
