I have been trying to figure out how to fix some shift reduce conflicts I have. I have looked around and found different topics on fixing it but it seems like no matter what I do I just can't seem to find a way to fix these issues.
I am trying to write a grammar class for Angel Script a popular scripting engine I got the BNF grammar from the parser class. You can find the language reference here http://www.angelcode.com/angelscript/sdk/docs/manual/doc_script.html
And within my class for each rule I addde a comment of the BNF grammar Im trying to copy. At the moment I don't actually use the keywords I define. I will go back and try and clean it up once I can get it working without conflicts. Here is my class http://pastebin.com/FydCTqmU
You should be able to just create a Dll and run that with the grammar explorer and you'll see all the errors. It seems like most of the errors all come from the same issue so I think maybe once I can get that fixed it will fix almost everything.
EDIT: Here is the main issue. That is the main script state, I know its broken up into a lot of different rules but I did that so I could try and fix the issue which I still havent had luck with.
EDIT: I tried condensing my code to hopefully get passed the reduce-reduce errors but it seems to stay exactly the same but only looking way more cluttered. If anyone can help me get it right i'll be more then happy to send them a few hundred dollars via paypal. I'm at the point of just giving up its been over a week I've been on this.
