Supporting jupyterlab?

[dirkcgrunwald]

I'm curious if anyone has gotten this to work using JupyterLab rather than e.g. jupyter notebooks.

I'm installing it using

cd /opt && \
git clone https://github.com/dirkcgrunwald/mobilechelonian.git && \
cd mobilechelonian && \
python setup.py install

in my setup (docker / zero2jupyterlab setup).

When running the example I get "Error creating widget: could not find model" which appears to mean I haven't done a "jupyter labextension install" -- but even if I do that, doesn't work.

Not certain what Fine Manual to read to offer a patch since i haven't authored ipywidgets or jupyterlab widgets before.

I think some work would need to be done to get this working in JupyterLab (it'd need to be a Lab extension instead of a Notebook extension). However I think this would be valuable work to be done - JupyterLab would be great since you could have the turtle in one window pane and the code in another

In my Jupyterlab I do not see any errors but also no graphics output.
Only:

Turtle()
Turtle()
Turtle(points=[{'p': 1, 'y': 200, 's': 1, 'x': 200, 'lc': 'black', 'b': 0}])

It could be easiest to reimplement the drawing using ipycanvas. For a proof of concept see https://github.com/uh-comp-methods1/intro/blob/main/kilpikonna.py and the associated notebook https://github.com/uh-comp-methods1/intro/blob/main/turtle_graphics.ipynb. My quick and dirty solution uses NumPy and it implements just right, left, forward and backward.
