Re: Proposal for batch plotting


Has anyone written a context free grammar specification like BNF? If its
recursive descent that would indicate an LL parse. There are lots of tools
out there to generate highly efficient tables for parsing and scanning.

It looks it's designed to drive a recursive descendant parser with no
lookahead (well, it with the prev_token you could do lookahead, altough not
so easily). Am I right?

Seems easy enough to use, actually...

Exactly, it already contains 90% of the needed stuff...
