Well, it probably isn't useful for JRuby, but Groovy had a similar problem but solved it by implementing Java 5 Annotations processing as part of it's compiler. There is even an example by Danno Ferrin (Grape's "@grab" annotation) which hooks into an early compiler phase to pull in classpath dependencies. I believe all this Groovy compiler and language extension stuff is being standardized (as far as Groovy is concerned that is) around the Groovy AST API.
As for myself (for IFCX Wings, new version coming soon!) I'm sticking with Javadoc-style annotations for things that need to be preprocessed (an "@uses" annotation for Ivy/Maven dependencies in particular). Among other things, that makes it easy to have an API (and syntax) that works for many languages. Jim Charles Oliver Nutter wrote: > Ok, I've got a problem.
