Official Haskell GHC compiler plugin distributed in Vim's runtime.
To be used for the :make command in order to properly load errors and warnings
on the quickfix list.
If your Vim's runtime is up to date you should already have it, if not, you can install it as a normal plugin.
Compatible with Vundle, Vim-plug, Pathogen, etc.
Set the compiler with :compiler ghc.
Or add an auto command to your .vimrc file:
augroup ft_haskell
au!
au FileType haskell compiler ghc
augroup END
