Rathi's Nix Config

This repo is the source of truth for your macOS setup, built with:

• nix-darwin for system settings
• home-manager for home directory files
• upstream flakes where that is the cleanest package source, such as github:googleworkspace/cli
• nix-homebrew plus homebrew.* only for the small set of apps and holdouts still kept in Homebrew

Current approach

The repo now owns the active shell/editor/tool config directly:

• home/ contains the Home Manager modules for user-facing tools
• config/ contains the repo-owned config trees copied from your daily setup
• modules/homebrew.nix is intentionally narrow and should keep shrinking over time
• Homebrew cleanup is still set to "none" so the first switch is non-destructive

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/packages.nix: system packages and fonts
• modules/homebrew.nix: the remaining Homebrew-managed apps and packages
• home/: Home Manager modules for shell, editor, CLI tools, and app config
• config/: repo-owned config files consumed by Home Manager

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

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
• Anything that depends on local credentials, keychains, or encrypted stores
• Deciding whether the remaining Homebrew entries should stay there or be eliminated

Current Homebrew Scope

The current Homebrew boundary is intentionally small:

• CLI holdouts: memex, postgresql@17, python@3.13, graphite, worktrunk
• GUI apps: cap, raycast, thebrowsercompany-dia, wispr-flow

If you want a zero-Homebrew machine, this is the list that still has to be replaced or intentionally dropped.
