Re: [Codenarc-developer] PMD Integration ?

[Hamlet D. <ham...@ca...>]

So is there a generic AST API that PMD will provide and we need to adapt CodeNarc to that? 

One thing I really like about PMD is the XQuery syntax for rules. I have wanted to port that to CodeNarc but maybe what we need to do instead is port CodeNarc to PMD. 

If there is a generic API then please send a link. I'd like to read it. There are many things that are possible in Java that are not possible in Groovy because there is no type information. How did ECMAScript handle that?
