In creating and enhancing XTRAN, my Expert System that knows over 40 computer languages, I got tired of hard-coding parsers, so I created a parsing engine that takes EBNF (specified in more friendly syntax I created), parses the EBNF to an internal format, and then when asked to parse a language, executes its EBNF in order to parse. I would be interested to know if anyone else is executing EBNF to parse. Since code must come back out after XTRAN rules have created / changed / translated it, I also created a rendering engine that is responsible for rendering XTRAN's internal format of language content out as text source code, complete with extensive styling controls. The rendering engine is also driven by EBNF, which it executes in order to render code content to text source code. If you're interested in learning more, see WWW.XTRAN-LLC.com. I'll be glad to answer any questions.
