This would be huge, but awesome. http://en.wikipedia.org/wiki/GLR_parser
I'm considering doing this right now. Please let me know if anyone already has this implemented.
No, I hadn't begun this yet. Jison has LR(1), but it's too slow to be practical for real-world languages. Were you also planning to implement a fast LR algorithm? When I had time, I was going to extend the LALR(1) generator to LR(1) using this algorithm.
So...no work has been done on this then?
No news on this?
