Re: [jupyter] Re: jupyterlab version of vpython

2018-05-22 Thread Matt Craig 
I'm a little biased, but like the idea of moving towards an 
ipywidgets-based interaction with the notebook (i.e. vpython as a 
widget)can probably help with that later this summer once SciPy is done 
:)

Re: [jupyter] Re: jupyterlab version of vpython

2018-05-22 Thread Jason Grout 
Right, JLab uses it's own extension system, and webpack to bundle
javascript up, and does not use require or the nbextension system.

I think maybe you can do something like this for the first steps:

1. Write an npm package containing the vpython javascript. JLab extensions
are fundamentally npm packages containing some extra metadata.
2. Write a very simple extension (perhaps like the beginning steps of the
xkcd extension?) whose sole purpose is to get the js on the page. You do
this by importing the vpython js modules into your main extension file that
JupyterLab loads.
3. Decide how vpython is going to display. It seems that there are lots of
parallels with ipywidgets and vpython, so you might look to ipywidgets for
inspiration. For example, we now display using the ipython display system
and a custom widget mimetype and custom mimetype renderer.

My understanding is that webpack is used, but that’s based on the tutorials I 
read. Have I got that right?

Ack! Of course my browser cleverly turned "vpython" into "python" and I 
didn't catch it!

sorry.
