Hi
{-# OPTIONS -fglasgow-exts #-} module Blog.Types where import Data.Typeable import Data.Generics
data BlogEntry = Entry EpochSeconds Name Email Title Body deriving (Eq,Ord,Read,Show,Typeable)
newtype Name = Name String deriving (Eq,Ord,Read,Show,Typeable) newtype Title = Title String deriving (Eq,Ord,Read,Show,Typeable) newtype Body = Body String deriving (Eq,Ord,Read,Show,Typeable)
First off, never use OPTIONS, use OPTIONS_GHC instead. OPTIONS is the old way of doing it. Secondly, if you add {-# OPTIONS_DERIVE --derive=Eq,Ord,Read,Show,Typeable #-} then running your code through with Derive should give you the magic that you require. Plus it will also work on Hugs, and not require your OPTIONS_GHC anyway. Derive: http://www-users.cs.york.ac.uk/~ndm/derive/ Thanks Neil
