I'm working my way through Real World Haskell and am in Chapter 3. On page 56 there is a discussion called "Record Syntax" and it gives this data constructor: data Customer = Customer { customerID :: CustomerID , customerName :: String , customerAddress :: Address } deriving (Show) where CustomerID and Address were defined (and loaded) before. But when I try to put in data, I get these errors *Main> :load BookStore.hs [1 of 1] Compiling Main ( BookStore.hs, interpreted ) Ok, modules loaded: Main. *Main> customer1 = Customer 271828 "J.R. Hacker" ["255 Syntax Ct", "Milpitas, CA 95134", "USA"] <interactive>:1:11: parse error on input `=' *Main> <interactive>:1:18: parse error (possibly incorrect indentation) *Main> <interactive>:1:21: parse error on input `,' *Main> <interactive>:1:6: parse error on input `]' *Main> If I put the whole data add on one line, I still get *Main> customer1 = Customer 271828 "J.R. Hacker" ["255 Syntax Ct", "Milpitas, CA 95134", "USA"] <interactive>:1:11: parse error on input `=' *Main> I'm on Ubuntu 11.10, using Emacs23, haskell-mode, running 7.0.4. Any ideas what's going wrong? The book gives this alternate version: data Customer = Customer Int String [String] deriving (Show) customerID :: Customer -> Int customerID (Customer id _ _) = id customerName :: Customer -> String customerName (Customer _ name _) = name customerAddress :: Customer -> [String] customerAddress (Customer _ _ address) = address ...but it produces the same errors.
