FParsec is a parser combinator library for F#.

With FParsec you can implement recursive‐descent text parsers for formal grammars.

FParsec’s features include:

• support for context‐sensitive, infinite look‐ahead grammars,
• automatically generated, highly readable error messages,
• Unicode support,
• efficient support for very large files,
• an embeddable, runtime‐configurable operator‐precedence parser component,
• a simple, efficient and easily extensible API,
• an implementation thoroughly optimized for performance,
• comprehensive documentation,
• a permissive open source license.

Documentation

  ^{The new solution and project files in the source folders don't yet properly work within the Visual Studio 2017 IDE, but the old solution file in Build/VS11 still works fine.}
