## Using the stable version
|
|
|
|
The Emacs front-end is available from
|
|
[*stable* MELPA](http://melpa-stable.milkbox.net/). This package should
|
|
always be compatible with the latest version of ghc-mod from hackage.
|
|
|
|
To use stable *stable* MELPA add this to your `.emacs`:
|
|
|
|
```elisp
|
|
(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-mod`/`ghc-modi` binaries from hackage by doing:
|
|
|
|
```shell
|
|
% cabal update && cabal install ghc-mod
|
|
```
|
|
|
|
### Nix & NixOS
|
|
|
|
The installation is a little more involved in this environment as Nix needs some
|
|
ugly hacks to get packages using the GHC API to work, please refer to this

## Using the development version
|
|
|
|
The easiest way to hack on ghc-mod is compile it, then add `dist/build/ghc-mod`
|
|
and `dist/build/ghc-modi` to your `PATH` and add the `elisp/` directory to your
|
|
Emacs `load-path`.
|
|
|
|
Make sure you're not using the MELPA version of `ghc.el` otherwise you might get
|
|
all sorts of nasty conflicts.
