Parser, Generator for Java with the following requirements

Question

I am looking for a parser generator for Java that does the following: My language project is pretty simple and only contains a small set of tokens.

Output in pure R

Answer 1

You should use Rats... This way, you don't have to separate lexer and parser and then if you want to extend your project that will be trivial. It's in java and then you can process your AST in Java...
