Benefit of flake-parts?

[MarkusLohmayer]

I hope it is fine to ask this naïve question here: What are the benefits of using the flake-parts library for configuring machines and home manager?

Hey!

Arguably there are not huge benefits. The main benefits you get are

• An activation script (nix run) that works across platforms
  • This is nice when you use a single flake across Linux and macOS
• specialArgs (including flake itself, its inputs and outputs) uniformly passed to all nixos/ nix-darwin/ home-manager modules
  • This enables those modules to be aware of the flake inputs, for instance.
• a convenient command to update the primary inputs (which can be overriden)
