I admit it: I have neglected to directly talk about something that people who have been using Ki end up running into, and it’s about “pivot state” errors.

Just a quick announcement that I’ve open sourced a new statechart framework for SproutCore called Ki (pronounced “key”) that you can start using today. Ki provides full statechart support for what is described in David Harel’s original paper “Statecharts: A Visual Formalism For Complex Systems” in addition to other key features useful for today’s event-driver systems.

Parts of Ki were derived from the statechart framework that is already included with the latest SproutCore on github. At first I started to modify the original statechart framework to incorporate all the new features that Ki supports; however, I soon realized that it was just easier to start from scratch in order to make a proper implementation.

You can get the Ki framework by going to http://github.com/FrozenCanuck/Ki.
