Description

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.

Synopsis

Pretty typeclass

class Pretty a where Source #

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.

Constructors

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.
