GHC

Mac OS X 10.5 (Leopard)

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

install the Haskell Platform
install MacPort's ghc package

Mac OS X 10.6 (Snow Leopard)

Mac OS X 10.6.x (Snow Leopard) works with GHC, after you apply a simple patch. The problem is that GHC generates 32bit code, but gcc on Snow Leopard defaults to 64bit code on machines with processors that support it. The patch simply tells GHC to tell gcc work in 32bit:

Install the Haskell Platform
You will need to patch just this file:
- /Library/Frameworks/GHC.framework/Versions/Current/usr/bin/ghc-6.10.4
Insert -optc-m32 -opta-m32 -optl-m32 just before the last parameter. The last line in that file is rather long, and should now end like:
- -dynload wrapped -optc-m32 -opta-m32 -optl-m32 ${1+"$@"}
P.S.: If you have a different version of GHC than 6.10.4, then adjust the file name appropriately.
P.P.S.: Don't be tempted to just put an edited local copy of the script in ~/bin/ghc, or edit all the various GHC files in /usr/bin. There is a maze of twisty symlinks that all eventually lead to the above script, and fixing just it is far simpler.

HUGS

install MacPort's hugs98 package.

Editors with Haskell support

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

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.

Shipping Installable Haskell Applications

mkbndl builds installable Mac OSX applications from your Haskell project.
