Mac OS X
1 The Haskell Platform
There are Mac OS X installers of the full Haskell Platform development environment. We recommend it:
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:
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:
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
> 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
- MacVim, a graphical Vim version
- Vim, is installed on every Mac
- Yi (written in Haskell itself!), is available through cabal-install
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.
