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).

• 🐧 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

1. Install NixOS (if not already installed)
2. Clone this repository to your system
3. Set up secrets (see Secrets Management section)

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

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

# Update flake inputs
nix flake update

# Update specific input
nix flake update nixpkgs

# Build without switching
nix build .#arifinoid

This configuration supports two secret management approaches:

• 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)

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

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

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

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

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

Edit the appropriate configuration file:

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

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

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

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

• NixOS Manual
• Home Manager Manual
• NixVim Documentation
• SOPS Documentation

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.
