FUNCTIONAL PEARL Parallel Parsing Processes
Koen Claessen · Journal of Functional Programming · 2004
We derive a combinator library for non-deterministic parsers with a monadic interface, by means of successive refinements starting from a specification. The choice operator of the parser implements a breadth-first search rather than the more common depth-first search, and can be seen as a parallel composition between two parsing processes. The resulting library is simple and efficient for “almost deterministic” grammars, which are typical for programming languages and other computing science applications.
