Are volunteering to write up some docs? There's not really much to document. Just check out the code from Subversion and read the comment at the top of groovyEngine/script.cfm. You can optionally read the comment atop groovyEngine/setPath.cfm for more advanced usage.

CF is a templating language that has had some OO-like stuff cobbled on. Groovy is an OO language that doesn't really do templating (though it does have a primitive templating framework). CF is good at the view, Groovy is good at the back end.

I'm planning to add Groovy object support to ColdSpring, so you can transparently use CF Groovy to load Groovy classes with ColdSpring. But that's for more advanced usage. If you just want to embed Groovy scriptlets, it's completely framework agnostic.

Like so many other things, necessity is the mother of invention. If you don't know why you'd want to use Groovy (or really why you wouldn't want to use CF), you probably don't have a need to use it. If CF is sufficient for the task at hand, CF's likely the right choice.

I for one have very much interest in Your "CF with Groovy" efforts :-) ! When will You make it publicly available with enough documentation to get us all up to speed :-) ?

Until now I have been a ColdFusion purist; but recently I have come to think that leveraging Java – e.g. for the domain modeling – could be in one's best interest …

So one has several choices:
- Leaving the ColdFusion camp completely and perhaps enter the Grails/Groovy community
- Still use ColdFusion where it is appropriate and leverage Your "CF with Groovy" micro framework where it is appropriate

The questions are then:
- What can ColdFusion still do better than Grails/Groovy ? The following items come to mind immediately: Event gateways; CFCs which can be configured to return JSON, XML, or web services; existing CFC functionality; tags like cfoutput …
- Which CF framework do You recommend for leveraging Your micro framework "CF with Groovy" to its fullest potential ?
- As somebody who has NOT been in the ColdFusion/Java/Grails/Groovy trenches himself, it may be difficult to judge in which situation to leverage which approach; so yes: some guidelines/explanations with regard to that complex topic could be valuable, too :-) !

I am looking forward to "CF with Groovy" :-) !

Best Regards and Tschüss
