While the proposal is aimed at improving the single-shot mode use case, I don't see a reason why this wouldn't work in make mode: GHC would report dependencies of all modules being built.
Ok cool, that's what I thought.
Is there a use case you have in mind where that would be useful?
I'm just a bit sceptical that fully switching to single-shot mode is actually a good idea in all cases so I'd like to keep --make at feature parity. However I do have a particular use-case in mind as well: Instead of having one --make instance per-package I'd like a sort of build-plan wide GHC server process to allow more sharing of in-memory build products. I think other people have been playing with that idea too so it's not exactly new but in the context of Haskell-IDE-Engine this might actually be something that makes a lot of sense to do because we already have what is essentially a GHC server process running the whole time, namely HIE itself. --Daniel
