-- | Pretty printing class similar to Show.
--   
--   Pretty printing class similar to Show, based on the HughesPJ pretty
--   printing library. Provides the pretty printing class and instances for
--   the Prelude types.
@package prettyclass
@version 1.0.0.0

-- | 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. Based on Text.PrettyPrint.HughesPJ,
--   which is re-exported.
module Text.PrettyPrint.HughesPJClass

-- | 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.
class Pretty a
pPrintPrec :: Pretty a => PrettyLevel -> Rational -> a -> Doc
pPrint :: Pretty a => a -> Doc
pPrintList :: Pretty a => PrettyLevel -> [a] -> Doc

-- | Level of detail in the pretty printed output. Level 0 is the least
--   detail.
newtype PrettyLevel
PrettyLevel :: Int -> PrettyLevel
prettyNormal :: PrettyLevel

-- | Pretty print a value with the prettyNormal level.
prettyShow :: Pretty a => a -> String

-- | Parenthesize an value if the boolean is true.
prettyParen :: Bool -> Doc -> Doc
