Following haskell-mode.

1. Use MELPA repository: add the following into ~/.emacs

(require 'package) (add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/packages/") t) (package-initialize)

1. M-x package-refresh-contents

2. M-x package-install [RET] haskell-mode

Usage

1. Open a haskell file in emacs;

2. Use "C-c C-z" to open ghci (but there isn't a jump-back shortcut, you can use C-x o);

3. Use "C-c C-l" to load file (same as ":l ");

However, there isn't tab-completion in the ghci invoked by "C-c C-z", so you can start a console to run ghci;
