[Pharo-dev] Extending a Class by adding an Instance Variable

SmalltalkVimMode adds an instance variable to RubSmalltalkEditor so it can track whether it is in normal/insert mode, etc. Currently, the inst var is undeclared when the project is loaded and one has to manually edit the class def to add it. Is there an elegant way to handle this? I can't think of a way that isn't awkward, dirtying packages, or leaving zombie objects around when editors close... ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
