Hello,
We are a shop using Groovy and Drools to enable end users to write
business logic (rules and utility libraries). I was wondering if there
are any plans to resurrect Groovy as a dialect? We may be interested in
contributing to such an effort. Can anyone point me in the right
direction of how to implement a dialect? I looked at the Dialect
interface and the Java and MVEL implementations a bit, but there seems
to be a lot of code there. Any guidance on what the minimum set of
functionality is needed to get things working at a basic level?
Thanks,
Tom Davidson

If you follow how we hook in MVEL that should cover it. We have no
direct plans to resurrect Groovy, as MVEL imho provides everything we
need and is type safe. As we start to add more verification and anlaysis
to Drools type safety will be important.

Groovy was important pre drools 3, when much of the rule logic was in
the semantics of the dialect - but since drools 3(!) that hasn't
really been the case, but it is certainly possible.
