I have a book on Haskell, and I've downloaded and installed Haskell Platform for Mac OS X. What do I do now? XCode is a requirement, and I have it, but I don't know how to run it. To begin with, I want to test small examples from the book, using ghc or ghci. I have read file:///Library/Haskell/doc/start.html.
- Where is the software I've just installed? - How is ghci started? Or the "platform", whatever that is?
The location of the software is covered in /Library/Haskell/doc/start.html. The key point is that the executables - like ghci - are in your path via /usr/bin. What they mean by "should be available in any shell", is that when you run Terminal, you can just type "ghci" at the prompt. Terminal may be hiding in Applications/Utilities. Apple clearly underestimates the value of this application for its users, but you won't - you're going to be using Terminal a lot, for GHC. You need XCode only because GHC needs its compiler and libraries, you won't use XCode directly yourself just to run examples from the book. Donn
