Hi very sorry for the 6 week delay(!), someone at AICrowd very kindly just brought your note to my attention.
Yes it appears the author of the jpy_canvas extension removed it from his public github some months ago; I think it had stopped working with the latest jupyter some time earlier. I think it’s just about possible to get things working by pinning to old versions but that’s not the way any of us want to go.
At some point I expect we will refresh the editor to work with the newer, more maintained canvas extension ipycanvas (github) but there are no immediate plans for this.
We’ve done a couple of bits of related work in the last 6-9 months:
- one of which involved converting some real layout data into flatland environments.
- using manually coded coordinate strokes (like mouse-strokes in the editor) to create specific environments.
These both used some of the old editor code to handle some of the logic of joining rails etc. (The older hand-coded test environments literally had to have explicit decimal / binary numbers representing the transitions)
I’ll try to put some information together, maybe in a branch. Please ping us again here or in an issue if you’re still interested in this.
Many thanks!
