1 Introduction

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.

The latest stable release with Haddock documentation is available on Hackage and development versions are available via the darcs repository.


2 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 language , unlike Happy parsers, which must be generated via a preprocessor.

An example for parsing a simple grammar of expressions can be found here.

Much more documentation can be found on the parsec website.
