EXPERIMENTAL

Write Emacs module in Haskell, using Emacs 25's Dynamic Module feature.

* Only tested with linux.
* You need to build emacs with --with-modules configuration options
* You need to specify some ghc-options to make it work work

Sample:

    {-# LANGUAGE ForeignFunctionInterface,OverloadedStrings #-}
    module Main where

    import Emacs

    foreign export ccall "emacs_module_init" emacsModuleInit :: EmacsModule

    emacsModuleInit :: EmacsModule
    emacsModuleInit = defmodule "sample-module" $ do

      setVal "foo" (Symbol "bar")

      defun "square" $ \i -> do
        message "haskell squre function called"
        return $ (i*i :: Int)
