Text.PrettyPrint.HughesPJClass

Pretty printing class, simlar to Show but nicer looking.

Note that the precedence level is a Rational so there is an unlimited number of levels. This module re-exports HughesPJ.

Pretty typeclass

class Pretty a where

Pretty printing class. The precedence level is used in a similar way as in the Show class. Minimal complete definition is either pPrintPrec or pPrint.
