haskell-compile behaviour

[vasanthaganeshk]

haskell-compile could work based on something similar to haskell-process-type. Despite the presence of stack.yaml file haskell-compile tries to use something.cabal file. We could implement some kind of priority, we could also take a Makefile into consideration if present.

• Potential files to work with:
  • haskell-compile.el

My half tought out ideas:

• use projectile to manage project root, which could be either a .cabal or stack.yml file
• compile based on that

projectile would allow us to store per-project configuration, like how to invoke cabal configure or stack in this specific directory.
