00:58 idiosyncrat Demat!
00:59 idiosyncrat aindilis: Years ago Jean-Damien did a lot with auto-translation of various BNFs (I take it you are talking about BNF from standards for those languages).
01:01 idiosyncrat In principle, it's easy, but the fact is that the BNF in the standards almost never is exact.  For example, it won't define what's a lexeme and what's not, without which knowledge it's impossible to create a parser.
01:03 idiosyncrat Most of the respects in which Marpa::R2's DSL differs from standards BNF is simply that -- Marpa's DSL, since it's not just intended for a human reader, but also can produce a real, practical, parser, has to demand certain things be specified that the standards writer can omit in favor of a easier-to-read grammar.
01:04 idiosyncrat Also, it's not rare for standards BNF to contain small errors, or be vague about the more tedious details.
01:06 idiosyncrat Jean-Damien had been busy elsewhere recently, but I think (hope) he lurks from time to time.  In any case, here's his github: https://github.com/jddurand
01:07 idiosyncrat https://github.com/jddurand/c-marpaEBNF
01:09 idiosyncrat That's one of Jean-Damien's repos, I don't know if it's the most relevant.
01:09 idiosyncrat aindilis: Good luck!
