Text.PrettyPrint instances and rendering functions for Qux language elements.
To render a program, call: render $ pPrint program
- class Pretty a where
- pPrintPrec :: PrettyLevel -> Rational -> a -> Doc
- pPrint :: a -> Doc
- pPrintList :: PrettyLevel -> [a] -> Doc
- data Style :: * = Style {
- mode :: Mode
- lineLength :: Int
- ribbonsPerLine :: Float
- data Mode :: *
- render :: Doc -> String
- renderStyle :: Style -> Doc -> String
- renderOneLine :: Doc -> String
Types
class Pretty a where
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
pPrintList :: PrettyLevel -> [a] -> Doc

to a String using the given Style

, but renders the doc on one line.
