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 printing class. The precedence level is used in a similar way as in the Show class. Minimal complete definition is either pPrintPrec or pPrint.
pPrintPrec :: PrettyLevel -> Rational -> a -> Doc Source
pPrintList :: PrettyLevel -> [a] -> Doc Source

newtype PrettyLevel Source
Level of detail in the pretty printed output. Level 0 is the least detail.
| PrettyLevel Int |
prettyNormal :: PrettyLevel Source
The "normal" (Level 0) of detail.
prettyShow :: Pretty a => a -> String Source
Pretty print a value with the prettyNormal level.
prettyParen :: Bool -> Doc -> Doc Source
Deprecated: Please use maybeParens instead
Parenthesize an value if the boolean is true.
