var quantificationBehavior: AST.Quantification.Kindmutating func finish() -> String mutating func indent() Indents a new line, if at the start of a line, otherwise does nothing.
mutating func output(_ s: String) Outputs a string directly, without termination or indentation, and without updating any internal state.
mutating func popMatchingOptions() -> ([AST.MatchingOption], Bool) Pops the most recent list of matching options from the printer and decreases the indentation level by 1.
mutating func print(_ s: String) Print out a new entry.
mutating func printAsCanonical(_ ast: AST, delimiters: Bool = false, terminateLine terminate: Bool = true) Outputs a regular expression abstract syntax tree in canonical form, indenting and terminating the line, and updating its internal state.
mutating func printIndented(_ f: (inout PrettyPrinter) -> ()) Executes f at one increased level of indentation.
mutating func printLine(_ f: () -> String?) Prints out a new entry by invoking f until it returns nil.
mutating func pushMatchingOptions(_ options: [AST.MatchingOption], isAdded: Bool) Pushes the list of matching options to the current stack of other matching options and increases the indentation level by 1.
mutating func terminateLine() Terminates a line, updating any relevant state.
