Rathi's Nix Config

This repo is the start of a full-machine macOS setup built with:

• nix-darwin for system settings
• home-manager for home directory files
• nix-homebrew plus homebrew.* for the large set of macOS packages and casks that still make sense to manage through Homebrew

The friend config under tmp/dots is kept here as reference material only. The config in this repo is your own scaffold.

Current approach

The migration is intentionally conservative:

• Homebrew inventory is captured declaratively in modules/homebrew.nix.
• Your live dotfiles stay the source of truth for now via out-of-store symlinks from home/dotfiles.nix.
• Cleanup is set to "none" so the first switch does not delete anything you forgot to inventory.

That gives you a reproducible baseline without forcing a risky rewrite of shell/editor configs on day one.

Layout

• flake.nix: top-level flake and host wiring
• hosts/hari-macbook-pro/default.nix: this machine's host config
• modules/base.nix: Nix settings and core packages
• modules/macos.nix: macOS defaults and host-level settings
• modules/homebrew.nix: taps, brews, and casks from the current machine
• home/dotfiles.nix: Home Manager symlinks into ~/dots
• docs/machine-audit.md: inventory and migration notes from the current box

Commands

Bootstrap the host:

nix run github:LnL7/nix-darwin/master#darwin-rebuild -- switch --flake .#hari-macbook-pro

After the first successful switch:

just switch
just build
just check

Capture a fresh machine inventory before any destructive changes:

./scripts/snapshot-machine.sh

What Still Needs Manual Work

• Secrets and tokens under ~/.secrets, ~/.npmrc, ~/.config/gcloud, ~/.config/gh, and similar paths
• Launch agents that are currently outside Nix
• App state under ~/Library/Application Support
• Apps installed outside Homebrew casks or the App Store
• Translating raw files from ~/dots into pure Home Manager modules over time

The snapshot script writes raw inventories under inventory/current/ so you can diff the machine state over time instead of relying on memory.

Important Note About Dotfiles

Your live machine currently points at ~/dots, not ~/Documents/GitHub/dots. This config follows the live machine and expects ~/dots to exist.
