Happy Haskell programming on Emacs/Vim
For Vim users: see https://github.com/eagletmt/ghcmod-vim
For Emacs users: read the followings:
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)))
(add-hook 'haskell-mode-hook (lambda () (ghc-init) (flymake-mode)))
If you have customized GHC import-path like follows,
(setq ghc-flymake-check-includes '("dir1" "dir2"))
You may update your settings as follows.
(setq ghc-ghc-options '("-idir1" "-idir2"))
(setq ghc-ghc-options '("-idir1:dir2"))
Now, you can simply pass GHC options to ghc-mod sub-commands.
