@hackage ghcid0.2

Either "GHCi as a daemon" or "GHC + a bit of an IDE". A very simple Haskell development tool which shows you the errors in your project and updates them whenever you save. Run ghcid --height=10 --topmost --command=ghci, where --height is the height of the console you will use, --topmost makes the window on top of all others (Windows only) and --command is the command to start GHCi on your project.
