Haskell Mode for Emacs

Build Status Melpa Status Melpa Stable Status

This is the Haskell mode package for Emacs.

Please see the online haskell-mode manual for setup and use guide.

To report problems or suggestions, please open an issue in the issue tracker.

Below is a brief setup guide.

Quick Emacs rundown

When Emacs is started up, it normally loads the Emacs initialization file usually called ~/.emacs, ~/.emacs.el, or ~/.emacs.d/init.el; with ~ standing for for your home directory. This file should contain all of your personal customisations written as a series of Emacs Lisp commands. In the following sections, this file will simply be referred to as the .emacs file.


GNU Emacs version 23 or later is officially supported. It may work with other Emacsen, but we don't have the resources to support other versions.

There are many ways to install haskell-mode. The following sections describe the most common ones; pick the one that you're most comfortable with.

package.el-based Installation

This is the recommended way

package.el is the new built-in package manager included in Emacs 24.x. On Emacs 23.x you will need to download package.el yourself and place package.el somewhere in your load-path.


Stable releases of haskell-mode are available on Marmalade.

If you're not already using Marmalade, add the following snippet to your .emacs and evaluate it with M-x eval-buffer:

(require 'package)
(add-to-list 'package-archives
             '("marmalade" . ""))

Refresh the package index by M-x package-refresh-contents and install haskell-mode via M-x package-install [RET] haskell-mode.

Alternatively, you can also download the .tar file via the Download link at and install the package .tar-file via M-x package-install-file

Note that in this case you will also need to have a sufficiently recent version of cl-lib.el, upon which haskell-mode depends. This is bundled with Emacs 24.3 and later, and a backported version for use with older Emacs versions can be obtained from GNU ELPA.


Development snapshots can be installed via the MELPA community maintained repository.

For MELPA the code you need to add is:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "") t)

Refresh the package index by M-x package-refresh-contents and install haskell-mode via M-x package-install [RET] haskell-mode.

el-get based Installation

el-get is another popular package manager for Emacs. If you're an el-get user just do M-x el-get-install to get haskell-mode installed.

Emacs Prelude

haskell-mode is bundled with Emacs Prelude. If you're a Prelude user you can start using it right away.


If you are using Debian, you can install an older version (e.g. Wheezy ships with version 2.8.0) of haskell-mode with a command like:

$ apt-get install haskell-mode

Installation from Git

This installation method requires more work and recommended for haskell-mode developers/contributors only as it allows to load haskell-mode directly from the checked out Git working copy. If you just want to use bleeding edge versions of haskell-mode please use the MELPA installation method described above.

  • git clone into a suitable directory, e.g. ~/lib/emacs/haskell-mode/ where ~ stands for your home directory.

  • Assuming you have unpacked the various haskell-mode modules (haskell-mode.el and the rest) in the directory ~/lib/emacs/haskell-mode/, you need generate the autoloads file (haskell-mode-autoloads.el) by either

    • Invoking make haskell-mode-autoloads.el, or make all (use this to perform byte-compilation and Info manual generation)

    • From inside Emacs, M-x update-directory-autoloads and answering the question for the folder with ~/lib/emacs/haskell-mode/ and the question for the output-file with ~/lib/emacs/haskell-mode/haskell-mode-autoloads.el

    and then adding the following command to your .emacs:

    (add-to-list 'load-path "~/lib/emacs/haskell-mode/")
    (require 'haskell-mode-autoloads)
    (add-to-list 'Info-default-directory-list "~/lib/emacs/haskell-mode/")
  • After updating your haskell-mode working directory, you need to re-run make all or M-x update-directory-autoloads.

Basic Configuration

For setup instructions, please consult the new integrated haskell-mode Info manual which can be accessed after installation via M-x info-display-manual [RET] haskell-mode. Alternatively, you can also direct your browser to the the online haskell-mode manual for setup and use guide.
