Instances

render :: PPState -> State PPState () -> BuilderSource

Produce a builder from a pretty printer state computation.

renderBytes :: PPState -> State PPState () -> ByteStringSource

nlCol :: Word -> PPStateSource

Pretty printer state starting on a new line indented to the given column.

data PPOp Source

Operations we can perform while pretty printing.

Constructors

Indent Word

Indent by N spaces.

Bytes ByteString

Add bytes to the script.

Newline

Move to newline.

WordSeparator

Separate words with space.

Curly Bool

Introduce a level of braces.

Round Bool

Introduce a level of parens.

indentPadToNextWord :: State PPState ()Source

This procedure is used in printing statements within evals, to set up indentation correctly for lines following the first line. It ensures that the second and following lines are printed aligned with the first character of the first line of the statement, not the first character of the $(, >( or <( enclosing the eval.
