haskell - How can I quickly and easily configure GHC integration for Emacs? -


in past i've tried more ide experience while developing haskell in emacs, i've stumbled on not quite working integration.

is there way basic ghc-powered features (e.g. type of identifier or instant compile using flymake) works*. works mean integrates rest of ecosystem (e.g. haskell-mode, cabal)?

* works here means: requires basic configuration in init.el , perhaps installing package hackage.

for inline error checking, hdevtools best i've found. it's background server running ghc in order speed analyzing programs.

it's easy install: need 1 haskell package:

cabal install hdevtools

and 2 emacs packages, both through m-x list-packages: flycheck , flycheck-hdevtools.

once it's installed, need enable m-x global-flycheck-mode (which can put in .emacs.) can go next error c-x `. want change error , warning faces, can m-x customize-group flycheck-faces.

unfortunately, emacs mode only errors , warnings (including hlint); not expose retrieving type of identifier, believe hdevtools supports. gives me random parse errors when confronted unicode variable names or extensions; however, if ignore them, else works. should file bug report or something.
