Hi Warner – you may have all the reviewers you need, but if you want someone to take a look at the JavaCC bits I’d be happy too; just let me know. And best of luck with the book, sounds like a great project!

These past 6 months I have been investigating how we might provide support for external DSLs in Groovy. I was particulary keen to find a ‘groovy’ solution.

This led me to consider combinator parsers as a means of defining the language of the DSL. I have been able to implement a meaningful combinator library using Groovy closures. The code is surprisingly small by quite expressive. With the combinators I am able to directly express in Groovy the DSL grammar. One of the simple combinators then allows me to define a transformation of the parsed input into an AST.

Presently I am extending this work to incorporate error reporting. This too is a combinator that makes a parser report errors should it fail.

I would be pleased to discuss my work with you. I hope to get some stuff onto one of the Groovy blogs that describes all this.

Thanks all for the comments, I will be keeping everyone up to date on the progress of things.

@Tom – I’ll let you know if we lose any reviewers this round.

@Ken – Your work sounds really interesting let’s definitely chat!
