Happy Haskell programming on Emacs
Features:
1) Completions of keyword, module, class, function, types,
language extensions, etc.
2) Flymake with GHC and hlint
3) Inserting code template
The "ghc-mod" program written in Haskell is a backend to gather
information from GHC and hlint.
Elisp libraries including ghc-mod is an extension to haskell-mode.
You should put the followings in your "~/.emacs.el":
(autoload 'ghc-init "ghc" nil t)
(add-hook 'haskell-mode-hook (lambda () (ghc-init)))
or
(add-hook 'haskell-mode-hook (lambda () (ghc-init) (flymake-mode)))
