Doloro's Dotfiles

NixOS dotfiles managed via flake-parts + den (custom flake framework). Multi-host: desktop, laptop, WSL, RPi5 server.

Hosts

Host	Arch	Type	Key Modules
desktop	x86_64	NixOS + HM	Hyprland, gaming, disko, full stack
laptop	aarch64	NixOS + HM	Power management, Hyprland
wsl	aarch64	NixOS	WSL setup
doloro-bootable	x86_64	NixOS	Bootable USB recovery
rpi5	aarch64	NixOS	Server, no GUI

Key Tools & Stack

• Window Manager: Hyprland (primary), Niri (alternative)
• Editor: Nixvim (Neovim) — Gruvbox Material, LSP (rust-analyzer, nixd, tsserver), Treesitter, Lualine, Telescope, LazyGit
• Shell: Fish
• AI: Pi Coding Agent v0.81.1 (LiteLLM via scuggo proxy)
  • Models: meow (litellm), claude-opus-4-8, gpt-5.5, gpt-5.4-mini (recap/title)
  • Skills: pi-lens, pi-lean-ctx, pi-vitals, pi-spark, pi-caveman, pi-pretty, pi-context-engineering
• Terminal: Kitty
• Browser: Zen Browser, Helium
• Music: Spicetify (Spotify)
• Aurora: Stylix (themes), NixOS-Hardware
• Container: Podman
• Flatpak: nix-flatpak
• Secrets: SOPS + Age (6 keys for desktop/laptop user+system, rpi5)
• Nerd Fonts: Custom patched (Doloro1978/nix-nerd-fonts-patcher)

Conventions

1. Never edit flake.nix directly — run nix run .#write-flake to regenerate
2. Secrets live in config/modules/secrets/ — encrypted via SOPS age keys in .sops.yaml
3. Modules are modular: split by concern (ai, gaming, hyprland, power-management, services)
4. Hosts split into computers.nix and servers.nix — each host gets aspect references
5. Shared config lives in doloro-shared.nix — imported by all doloro hosts
6. Disko handles disk layouts for desktop/laptop
7. Power management is laptop-specific: TLP, auto-cpufreq, battery AC targets, Intel GPU, TDP
8. CachyOS kernel available as module for desktop

Common Operations

# Apply configuration
sudo nixos-rebuild switch --flake .#desktop

# Home Manager (doloro user)
home-manager switch --flake .#doloro-desktop

# Update flake inputs
nix flake update

# Write regenerated flake.nix
nix run .#write-flake

# Encrypt a secret
nix run .#sops-encrypt <file>

# Enter development shell
nix develop

Important Notes

• allowUnfree = true globally for proprietary packages (Steam, Spotify, etc.)
• Multiple cachix substitutes configured for speed (hyprland, nix-community, niri, raspberrypi, cuda)
• Pi coding agent uses scuggo LiteLLM proxy at https://9f5db439.fwds.scug.io
• API key via env var $SCUG_IO_API_KEY
• WSL host uses nixos-wsl flake input
• RPi5 uses nixos-raspberrypi and raspberry-pi-nix

File Rules

• .gitignore: exclude nix/result, result, nvim, tmux/plugins, modules/quickshell/quickshell/.qmlls.ini
• .new file exists (empty) — likely a marker
• .claude/ directory present (Claude Code config)
