Personally, if I have to rename a method, I search for all senders and fix them with copy&paste. Same for class renames, inst var renames, etc. There just are not that many occurrences, so fixing each one individually is quick, plus I get to verify that the change is indeed what I wanted. There is a tool to automate a lot of this called the Refactoring Browser, which many developers like, but I don't even have it in my image. - Bert - _______________________________________________ Beginners mailing list [email protected] http://lists.squeakfoundation.org/mailman/listinfo/beginners
