Silkscreen.Nesting

Synopsis

Printing with nesting levels

class Printer p => NestingPrinter p where Source #

Methods

askingNesting :: (Int -> p) -> p Source #

Make a printer informed by the current nesting level.

localNesting :: (Int -> Int) -> p -> p Source #

Locally change the nesting level for a printer.

applyNesting :: p -> p Source #

Apply the current nesting level to a printer.

Different instances can give different meanings to this, e.g. annotating the argument with the nesting level or some other means of rendering it differently.

Methods

askingNesting :: (Int -> Prec level p) -> Prec level p Source #

localNesting :: (Int -> Int) -> Prec level p -> Prec level p Source #

applyNesting :: Prec level p -> Prec level p Source #

incrNesting :: NestingPrinter p => p -> p Source #

Increment the nesting level of a printer.

This should be used inside parentheses, brackets, braces, etc., and will inform the annotation of their delimiters.
