## Overview
|
|
|
|
Nix flake managing 3 devices: Mac Mini, MacBook Air (both aarch64-darwin via nix-darwin), and a Windows PC via NixOS-WSL (x86_64-linux). Single user `imbytecat` everywhere.
|
|
|
|
## Architecture
|
|
|
|
```
|
|
flake.nix
|
|
├── darwinConfigurations.mac-mini (aarch64-darwin)
|
|
├── darwinConfigurations.macbook-air (aarch64-darwin)
|
|
└── nixosConfigurations.wsl (x86_64-linux)
|
|
```
|
|
|
|
- `lib/default.nix` — builders: `mkDarwin`, `mkNixos`, `mkHome`
|
|
- `modules/shared/` — both platforms (nixpkgs config, overlays, nix settings)
|
|
- `modules/darwin/` — macOS: system preferences, homebrew (casks/brews/masApps), fonts
|
|
- `modules/nixos/` — NixOS: base packages, docker, locale, user
|
|
- `home/` — home-manager (shared across all hosts via `useGlobalPkgs`)
|
|
- `overlays/` — custom packages (comment-checker)
|
|
|
|
## Nix implementation
|
|
|
|
All platforms use **Lix** (`nix.package = pkgs.lix` in `modules/shared/nix.nix`). Lix is a community fork of CppNix — same CLI, different implementation (partial Rust rewrite, ~20-30% faster, better error messages).
|
|
|
|
- macOS installed via [Lix installer](https://lix.systems/install/)
|
|
- `nix.enable = true` on all platforms — nix-darwin fully manages the Nix daemon, `/etc/nix/nix.conf`, and `nix.settings`
|
|
- `nix.settings` (flakes, warn-dirty) applies uniformly across all 3 devices
|
|
|
|
## Critical gotchas
|
|
|
|
- **catppuccin.nvim disabled**: `catppuccin.nvim.enable = false` in `home/theme.nix` due to `catppuccin.lib.detect_integrations` require check failure in nixpkgs. Re-test periodically.
|
|
- **catppuccin module name**: Uses `catppuccin.homeModules.catppuccin` (not the old `homeManagerModules`).
|
|
- **Homebrew tap casks**: Casks from taps need full path in the casks list (e.g. `"goooler/repo/fl-clash"`), not just the short name.
|
|
- **`onActivation.cleanup = "zap"`**: Any brew formula/cask NOT declared in `modules/darwin/default.nix` WILL be removed on rebuild. Be comprehensive.
|
|
- **Repo location**: The repo lives at `~/Developer/nix-config`. Fish abbreviations (`rebuild`, `update`) reference this path.
|
|
- **First-time bootstrap requires sudo**: `sudo nix run nix-darwin -- switch --flake .#mac-mini` (not `darwin-rebuild` which doesn't exist yet).
|
|
|
|
## Commands
|
|
|
|
```bash
|
|
# Validate (eval only, fast)
|
|
nix build .#darwinConfigurations.mac-mini.system --dry-run
|
|
|
|
# Validate (actual build, catches runtime failures like require checks)
|
|
nix build .#darwinConfigurations.mac-mini.system
|
|
|
|
# First-time bootstrap (nix-darwin not yet installed)
|
|
sudo nix run nix-darwin -- switch --flake .#mac-mini
|
|
|
|
# Daily rebuild (after first bootstrap)
|
|
sudo darwin-rebuild switch --flake .#mac-mini
|
|
|
|
# WSL rebuild
|
|
sudo nixos-rebuild switch --flake .#wsl
|
|
|
|
# Update all inputs
|
|
nix flake update
|
|
```
|
|
|
|
## Shell
|
|
|
|
Fish (not zsh). All tool integrations use `enableFishIntegration`. Key files:
|
|
- `home/shell/fish.nix` — abbreviations, interactiveShellInit
|
|
- `home/shell/tools.nix` — fzf, atuin, zoxide (`--cmd cd`), direnv, bat, eza, yazi, btop
|
|
|
|
## Home Manager option API (current)
|
|
|
|
These options were renamed in recent home-manager; use the new names:
|
|
- `programs.git.settings.user.{name,email}` (not `userName`/`userEmail`)
|
|
- `programs.git.settings.*` (not `extraConfig`)
|
|
- `programs.delta.{enable,options}` (not `programs.git.delta.*`)
|
|
- `programs.delta.enableGitIntegration = true` (must be explicit)
|
|
- `programs.ssh.matchBlocks."*".addKeysToAgent` (not top-level `addKeysToAgent`)
|
|
- `programs.ssh.enableDefaultConfig = false` (set explicitly)
|
|
|
|
## Nix LSP
|
|
|
|
Uses `nixd` (not `nil`). nixd provides nixpkgs/option completion; nil does not. Installed via `home/dev/languages.nix`.
|
|
|
|
## Formatter
|
|
|
|
`nixfmt` (was `nixfmt-rfc-style`, now unified). Run: `nixfmt <file.nix>`
