Re: [rules-dev] Functional programming in Drools: closures

I would also like to keep it as close to Java as possible. There are few problems here: * It could never go beyond Java * We are using Java 5 and just considering Java 6, this would be a huge leap :-) But then again if we don't use the Java way, then what will we do when Drools reaches Java 8, support both?

This is basically "closures" which will be available in JDK 8 + LHS closure pattern support 1) About "closures" which will be available in JDK 8: Since functions contain Java code, which is imperative, not declarative, I don't consider that DRL turf any more. *Our closure syntax should there should be exactly the same as Java 8.* Here's their syntax, which looks the same on first sight, but the devil is in the details (= unreleased spec): http://mail.openjdk.java.net/pipermail/lambda-dev/2011-September/003936.html Either we wait for JDK 8 to be released to support closures (current release date is 2012 according to Mark R.'s "plan B" that released JDK 7 in 2011) or we implement it just like the JDK8 with the exact same syntax (which is a LOT of work). 2) About LHS closure pattern support. This builds on top of 1) to allow usage of closures in the LHS. Cool stuff, I like the piping idea. Op 19-10-11 23:12, Mauricio Salatino schreef: Hi Mario, that document looks great.. I will take some time to read it and I will try to give some feedback. I was playing with cypher (from neo4j, a graph oriented DB) (total newbie on that) but looking at your in line acc functions I think that we can take some concepts from cypher and apply them in DRL.
