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?
Just write a RBParseTreeRewriter rule with specific elements to only activate inside blocks. Or a cascade: a RBParseTreeSearcher which matches blocks; on each block node you activate a rewriter. However, there is an issue in rewriting blocks contents, because it supposes that the method defining the block is recompiled; it's significantly harder to make changes to the code of live blocks (change the bytescode itself? What if the block has multiples instances?). Thierry
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,
