Hi Iâm trying to work out the best way to cope with the fact that we are in a hybrid place where the Playground is using an RubSmalltalkEditor but Calypso has its own mechanisms for editing code. I have commands that should/can work in both the playground as well as code method editor (in Calypso). Previously my code lived in RubSmalltalkEditor and Nautilus was using that too - but now Iâm not sure where to put some reusable methods that use RBParser and the AST to find the best place to position your cursor. I can make a class method on RubSmalltalkEditor and Calypso commands could reference that (but that feels wrong somehow). I could make some extension methods on RBParser and both places reference that - but then who should own the extension method (as I think RubSmalltalkEditor is lower level and Calypso is then loaded on top). Anyone have some good suggestions? Tim
