## Build commands
|
|
|
|
```bash
|
|
# macOS (from ~/dotfiles/nixos)
|
|
darwin-rebuild switch --flake .
|
|
|
|
# NixOS server (SSH from mac, or on server)
|
|
sudo nixos-rebuild switch --flake .#sunken-ship
|
|
|
|
# WSL
|
|
sudo nixos-rebuild switch --flake ~/dotfiles/nixos#wsl
|
|
|
|
# Update flake + rebuild (fish alias: nixupdate)
|
|
cd ~/dotfiles/nixos && sudo nix flake update && sudo darwin-rebuild switch --flake ~/dotfiles/nixos#Daniel-Macbook-Air
|
|
|
|
# Installer ISO (Linux only, cannot build on macOS)
|
|
cd ~/dotfiles/nixos && nix build .#installer-iso
|
|
```
|
|
|
|
## Rebuild protocol
|
|
|
|
**Never run rebuild commands automatically.** When changing Nix config files, always ask the user to rebuild first. Do not assume packages are available until after a successful rebuild.
|
|
|
|
## Flake architecture
|
|
|
|
- **Flake:** `nixos/flake.nix` — single flake for all hosts
|
|
- **Inputs:** nixpkgs-unstable, nix-darwin, home-manager, nixos-wsl, disko, zen-browser
|
|
- **Host configs** in `nixos/hosts/`:
|
|
- `daniel-macbook-air.nix` — hostname `Daniel-Macbook-Air` (aarch64-darwin, nix-darwin)
|
|
- `sunken-ship.nix` — NixOS home server (x86_64-linux)
|
|
- `wsl.nix` — WSL (x86_64-linux)
|
|
- `macbookair.nix` — old MacBook Air NixOS/WSL config
|
|
- `server-install.nix` — disko-install target (LUKS + WiFi)
|
|
- **Home Manager:** integrated via `home-manager.darwinModules.home-manager` on macOS; user config in `nixos/home/danny/home.nix`
|
|
- **Shared modules:** `nixos/fish.nix` (fish + bash), `nixos/tmux.nix`, `nixos/ollama.nix`
|
|
- **Darwin config name:** `Daniel-Macbook-Air` (must match in rebuild commands)
|
|
|
|
## Repo rules
|
|
|
|
- **Public repo** — no keys, tokens, or identifying secrets. Use `scp` or config outside the repo.
|
|
- **SSH keys:** one key per purpose (e.g. `id_ed25519_github`, `id_ed25519_servers`). Use `IdentityFile` + `IdentitiesOnly yes` in `~/.ssh/config`. Keys stay outside the repo.
|
|
- **Commit and push** before testing on sunken-ship — the server clones/pulls from origin.
|
|
|
|
## Server (sunken-ship)
|
|
|
|
- SSH: `ssh -i ~/.ssh/id_ed25519_sunken_ship danny@sunken-ship`
|
|
- Remote rebuild: `ssh ... 'cd /etc/dotfiles/nixos && sudo nixos-rebuild switch --flake .#sunken-ship'`
|
|
- Auto-rebuild timer: `dotfiles-rebuild` — only active after flake config switch. Check with `systemctl is-active dotfiles-rebuild.timer`.
|
|
- Server has WiFi; stays reachable when ethernet is unplugged.
|
|
|
|
## Ollama
|
|
|
|
Custom nix-darwin module at `nixos/ollama.nix` (upstream PR not yet merged). Enabled on macOS via `nixos/hosts/daniel-macbook-air.nix`. Runs as a launchd user agent with `ollama serve`.
|
|
|
|
## Alacritty (macOS)
|
|
|
|
Terminal colors follow **System Settings → Appearance**: `programs.alacritty` imports `~/.config/alacritty/active-colors.toml`; `scripts/alacritty-sync-system-theme.sh` copies Catppuccin latte/mocha there when the OS mode changes. **nix-darwin** `launchd.user.agents.alacritty-system-theme` polls every 30s; **fish** runs the same script on interactive startup. After changing Nix, one `darwin-rebuild switch`. Details: `assets/alacritty/README.md`.
|
|
|
|
## Shell
|
|
|
|
Fish is the default shell. Bash auto-execs fish unless the parent process is already fish. Vi keybindings with fzf integration. Zoxide aliased to `cd`.
