renderPretty :: Float -> Int -> Doc -> SimpleDocSource
This is the default pretty printer which is used by show
,
putDoc
and hPutDoc
. (renderPretty ribbonfrac width x)
renders
document x
with a page width of width
and a ribbon width of
(ribbonfrac * width)
characters. The ribbon width is the maximal
amount of non-indentation characters on a line. The parameter
ribbonfrac
should be between 0.0
and 1.0
. If it is lower or
higher, the ribbon width will be 0 or width
respectively.
displayS :: SimpleDoc -> ShowSSource
(displayS simpleDoc)
takes the output simpleDoc
from a
rendering function and transforms it to a ShowS
type (for use in
the Show
class).
showWidth :: Int -> Doc -> String showWidth w x = displayS (renderPretty 0.4 w x) ""
displayIO :: Handle -> SimpleDoc -> IO ()Source
(displayIO handle simpleDoc)
writes simpleDoc
to the file
handle handle
. This function is used for example by hPutDoc
:
hPutDoc handle doc = displayIO handle (renderPretty 0.4 100 doc)
