-- | 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 <a>Show</a> but nicer looking. Note
--   that the precedence level is a <a>Rational</a> so there is an
--   unlimited number of levels. Based on <a>Text.PrettyPrint.HughesPJ</a>,
--   which is re-exported.
module Text.PrettyPrint.HughesPJClass

-- | Pretty printing class. The precedence level is used in a similar way
--   as in the <a>Show</a> class. Minimal complete definition is either
--   <a>pPrintPrec</a> or <a>pPrint</a>.
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 <a>prettyNormal</a> level.
prettyShow :: Pretty a => a -> String

-- | Parenthesize an value if the boolean is true.
