Pretty typeclass
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
.

newtype PrettyLevel Source
Level of detail in the pretty printed output. Level 0 is the least detail.
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.
