There is also now the Mac OS X Strike Force that aims to improve using Haskell on OS X.

1 The Haskell Platform

There are Mac OS X installers of the full Haskell Platform development environment. We recommend it:

2 GHC

2.1 Important notes

To get the most out of your GHC environment, you should '~/.cabal/bin' to your PATH environment variable before the path where you have GHC installed. This will allow you to get and use cabal-updates, as well as other programs shipped with GHC like hsc2hs.

In you ~/.profile, add the line:

export PATH="~/.cabal/bin:$PATH";


2.2 Mac OS X 10.5 (Leopard)

To install GHC on Mac OS X 10.5 (Leopard), there are the following options:

2.3 Mac OS X 10.6 (Snow Leopard)

Mac OS X 10.6.x (Snow Leopard) works with GHC.

To uninstall ghc call: sudo /Library/Frameworks/GHC.framework/Tools/Uninstaller

3 HUGS


4 Installing libraries with external C bindings

Haskell libraries are installed with the cabal command line tool.

Some libraries depend on external C libraries, which are best installed with MacPorts. However, you have to tell cabal to include the /opt/local/ directories when searching for external libraries. The following shell script does that by wrapping the cabal utility

   > cat cabal-macports
   #!/bin/bash
   export CPPFLAGS=-I/opt/local/include
   export LDFLAGS=-L/opt/local/lib
   cabal $@ --extra-include-dirs=/opt/local/include \
            --extra-lib-dirs=/opt/local/lib
   > cabal-macports install foobar

5 Editors with Haskell support

5.1 Open Source

  • AquaMacs, a graphical Emacs version
  • Eclipse with the EclipseFP plugin
  • Emacs, is installed on every Mac
  • Leksah
  • MacVim, a graphical Vim version
  • Vim, is installed on every Mac
  • Yi (written in Haskell itself!), is available through cabal-install

5.2 Commercial

SubEthaEdit:

TextMate:

and Smultron:

TextEdit is Mac's default text editor, a very basic editor that works fine for most uses, you must however be careful to put it into plain text mode using the Format menu.
