Methods

accept(String input, {int start = 0}) → bool

Available on Parser<R>, provided by the AcceptParser extension

Tests if the input can be successfully parsed.
allMatches(String input, {int start = 0, bool overlapping = false}) → Iterable<T>

Available on Parser<T>, provided by the MatchesParserExtension extension

Returns a lazy iterable over all non-overlapping successful parse results of type T over the provided input.
and() → Parser<R>

Available on Parser<R>, provided by the AndParserExtension extension

Returns a parser (logical and-predicate) that succeeds whenever the receiver does, but never consumes input.
callCC<S>(ContinuationHandler<R, S> handler) → Parser<S>

Available on Parser<R>, provided by the ContinuationParserExtension extension

Returns a parser that when activated captures a continuation function and passes it together with the current context into the handler.
