Parser generator combinator
WebIt is simple, safe, well documented (on the package homepage), has extensive libraries, good error messages, and is fast. It is defined as a monad transformer that can be stacked on arbitrary monads, and it is also parametric in the input stream type. WebCombinator Parsing: A Short Tutorial S. Doaitse Swierstra January 5, 2009 Abstract There are numerous ways to implement a parser for a given syntax; using parser combinators is a powerful approach to parsing which derives much of its power and expressiveness from the type system and seman-tics of the host programming language.

In computer programming, a parser combinator is a higher-order function that accepts several parsers as input and returns a new parser as its output. In this context, a parser is a function accepting strings as input and returning some structure as output, typically a parse tree or a set of indices representing locations in the string where parsing stopped successfully. Parser combinators enable a recursive descent parsing strategy that facilitates modular piecewise const…
