Using the stable version
The Emacs front-end is available from stable MELPA. This package should always be compatible with the latest version of ghc-mod from hackage.
To use stable stable MELPA add this to your
(require 'package) (add-to-list 'package-archives '("melpa" . "http://melpa-stable.milkbox.net/packages/")) (package-initialize)
With this configuration you can install the Emacs front end from MELPA (the
package is called
ghc there, not
ghc-mod) and install the
ghc-modi binaries from hackage by doing:
% cabal update && cabal install ghc-mod
Nix & NixOS
ghc-mod works fine for users of Nix who follow a recent version of the
package database such as the
nixos-unstable channel. Just
include the package
ghc-mod into your
ghcWithPackages environment like any
other library. The Nixpkgs Haskell User's
covers this subject in great detail.
Using the development version
The easiest way to hack on ghc-mod is compile it, then add
dist/build/ghc-modi to your
PATH and add the
elisp/ directory to your
Make sure you're not using the MELPA version of
ghc.el otherwise you might get
all sorts of nasty conflicts.
Custom ghc-mod cradle
To customize the package databases used by
ghc-mod, put a file called
ghc-mod.package-db-stack beside the
.cabal file with the following syntax:
temp directory root package db 1 ... package db n
each package database line is either a path to a package database, or
If you have any problems, suggestions, comments swing by #ghc-mod (web client) on Freenode. If you're reporting a bug please also create an issue here so we have a way to contact you if you don't have time to stay.
Do hang around for a while if no one answers and repeat your question if you still haven't gotten any answer after a day or so. You're most likely to get an answer during the day in GMT+1.
