Dapar
Parsing for everybody.
Dapar is a universal parsing library written in C. It will interpret any grammar you give it in a BNF-like format, and constructs a matching expression tree for any given input. This makes developing a new parser for any language simple and reliable. Includes an ABNF parser, EBNF parser, XML parser and algebraic math parser. -
