# Doloro's Dotfiles

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

## Architecture

## 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

```bash
# 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)
