EBNF support

[zaach]

We could convert EBNF grammars to BNF. For this, we need an EBNF parser, a JSON representation, and a translation algoritm to convert the EBNF JSON to BNF JSON.

How's this going?

If you're interested, I've implemented a EBNF JSON to BNF JSON translator at https://gist.github.com/1591733, using rules from http://lamp.epfl.ch/teaching/archive/compilation-ssc/2000/part4/parsing/node3.html

Very nice -- this is pretty much what I had in mind. I'll work on integrating it this weekend. Thanks!

The latest master now has EBNF support. It'll show up on npm in the next version of jison (probably 0.3).

Awesome!

hey zaach, i am so glad to find this page! i was afraid that EBNF is not supported, because it is not mentioned here
http://zaach.github.com/jison/docs/#parsing-algorithms

please update that section :) and thank you for this awesome library!

[zaach]

It's not quite a parsing algorithm, but I'll make a note, thanks.

Yes. I can't figure out how to use EBNF in .jison
