Re: Online yacc/lex grammar editor/tester

[Domingo Alvarez Duarte]

Hello Hans !

I already know about that grammar and it's already there as "Cxx parser 
(not working)" because it uses "error" and auxiliary code to parse "C++" 
and the parser I'm using right now doesn't support "error" and at first 
it's mostly declarative only, anyway as the time goes by probably other 
ways to achieve the same can arrive.

Thank you for the feedback !
