Answer 1

I had good experience SableCC.

It works different from most generators, in that you're given a AST/Visitor model that you extend (via inheritance).

I can't comment on the "quality" of its code in terms of readability (it's been a while since I've used it), but it does have the quality that you don't have to read the code at all. Just the code in your subclass.
