1 Parsec

Parsec is an industrial strength, monadic parser combinator library for Haskell. It can parse context-sensitive, infinite look-ahead grammars but it performs best on predictive (LL[1]) grammars.

See the Parsec site for downloads and documentation.

1.1 Usage

Parsec lets you construct parsers by combining higher-order Combinators to create larger expressions. Combinator parsers are written and used within the same programming language as the rest of the program. The parsers are first-class citizens of the langugage, unlike Happy parsers, which must be generated via a preprocessor.

Much more documentation can be found on the parsec site.
