I've been using the Rete DSL a lot these days and was thinking that it could
be a good idea to provide some Eclipse infra-structure (syntax highlighting,
code completion, validation) to it using Xtext (
http://www.eclipse.org/Xtext/). It's built on top of antlr, so maybe we
could even reuse the grammar that we already have. I know that, by default,
you should right you grammar using their simplified version.
Maybe the guys there would also be interested in providing something to
Drools. It could be a showcase for them.
Not sure if this also applies to the Eclipse DRL things that we have.
Cheers,
Leonardo.
