Continuation-passing parser for context-free grammars

Documentation

newtype Parser g s r

Parser type for context-free grammars that uses a continuation-passing algorithm, fast for grammars in LL(1) class but with potentially exponential performance for longer ambiguous prefixes.

Constructors

Fields

• applyParser :: forall x. s -> (r -> s -> (FailureInfo -> x) -> x) -> (FailureInfo -> x) -> x
