Tau Parser

Industry-level C++ parsing library and parser generator, capable of taking any context free grammar and an input string, and producing the full parse forest, capturing all ambiguities efficiently.

GET STARTED

Give Tau Parser an arbitrary context-free grammar and an input string, and it’ll return all possible parse trees in a compressed graph with loops, from which you can get your desired parse tree.

Try TAU PARSER

The Tau Parsing Library goes beyond context free languages by fully supporting Boolean grammars which are the closure of context free grammars under union, intersection, and complementation. This subsumes priorities of productions and allows easier disambiguation.
