Hi guys, I have a very large kind of "rule engine" in which rules are written in smalltalk. These rules are saved as domain objects (imagine a rule kind of object) which end up having a closure. The code of those closure most of the time receives an argument and send messages to it. I want to add automatic method rename for rules. Let's say i have plenty of rules sending the message (rule) #price and now I want to refactor all senders to actually send #lastPrice. I am taking a look to RBRenameMethodRefactoring and friends. But I wonder if there is something specifically for managing blocks rather than methods/classes? If not, I think my easiest path is to automatically compile dummy/temporal classes/methods from the rules, perform the refactor, then move source from methods to block closures, and finally remove created classes. Any pointer is appreciated. best, -- Mariano http://marianopeck.wordpress.com
