parser generator parser generator Dragon object-oriented scanner parser solution

Dragon parser generator Description

A powerful parser generator. Dragon is a powerful parser generator. It produces a consequent, object-oriented, integrated scanner and parser solution. Dragon parser generator also scales for very large grammar defintions. Since dragon parses LR(1) grammars, the generation algorithm is quite CPU intensive.Using LR(1) instead of LALR decreases efficiency of the parser, but avoids some reduce/reduce conflicts in some cases. Dragon provides a very clean and structured way for the integration of application specific context code. Dragon combines the lexical and syntactical analysis and the corresponding code generation. What's New in This Release: · This release catches an infinite loop in the first set calculation for some complex grammars with epsilon productions.
