Functions

brew_available

brew_leaves

List installed brew formulae (top-level only, not deps).

brew_list_casks

darwin_rebuild_build

Run darwin-rebuild build (for diff). No sudo needed — build only.

darwin_rebuild_rollback

Run darwin-rebuild –rollback (requires sudo for system activation).

darwin_rebuild_switch

Run darwin-rebuild switch (requires sudo for system activation). After a successful switch, re-registers nix .app bundles with LaunchServices so Spotlight displays correct icons.

ensure_profile_dirs

Ensure home-manager profile directories exist. Determinate Nix on fresh macOS doesn’t create per-user profile dirs, which causes home-manager to fail with “Could not find suitable profile directory”. Also fixes ~/.local ownership if the install script created it as root.

find_nix

Resolve the path to the nix binary. Checks well-known locations first, then falls back to PATH-based lookup. Preferring hardcoded paths prevents PATH-based binary injection.

Show diff between current system and new build.
