render the document with defaultMode. render :: Doc -> String render = renderWithMode defaultMode

pretty-print with a given style and mode.

pretty-print with the default style and a given mode.

Pretty-printing styles (from Text.PrettyPrint.HughesPJ)

data Style :: * #

A rendering style. Allows us to specify constraints to choose among the many different rendering options.

Constructors

Style 

Fields

  • mode :: Mode

    The rendering mode.

  • lineLength :: Int

    Maximum length of a line, in characters.

  • ribbonsPerLine :: Float

    Ratio of line length to ribbon length. A ribbon refers to the characters on a line excluding indentation. So a lineLength of 100, with a ribbonsPerLine of 2.0 would only allow up to 50 characters of ribbon to be displayed on a line, while allowing it to be indented up to 50 characters.

Associated Types

type Rep Style 

style :: Style #

The default style (mode=PageMode, lineLength=100, ribbonsPerLine=1.5).

data Mode :: * #

Rendering mode.

Constructors

PageMode

Normal rendering (lineLength and ribbonsPerLine respected').

ZigZagMode

With zig-zag cuts.

LeftMode

No indentation, infinitely long lines (lineLength ignored), but explicit new lines, i.e., text "one" $$ text "two", are respected.

OneLineMode

All on one line, lineLength ignored and explicit new lines ($$) are turned into spaces.
