Difficulties in getting started with Imported Mode and Jupyter

[villares]

Hi,

I'm reading the tutorials, I found the tutorials may have a gap in terms of instructions on how to use Imported Mode. From reading other parts of the documentation I understood Imported Mode at this point works only on Jupyter notebooks.

You might want to investigate how Bernardo, first wih transcrypt and now following Luca Damasco's Pyodide proof of concept, is working on github.com/berinhard/pyp5js with the constants and "system variables" in the global namespace ...

Also, do you think we could manage a Google Collaboratory notebook or a http://MyBinder.org link with the environment ready for teaching?

Cheers,
Alexandre

Now that you've installed the kernel, is imported mode working for you?

For Mac users (you use a Mac?) py5 needs to be run using Jupyter because you need the %gui osx magic. See the Special Notes for Mac Users for more info.

For everyone else, there's also a command line tool called run_sketch that takes a file containing imported mode code as an argument. I haven't documented that yet though, and don't think it is that convenient. Using Jupyter is probably the best option.

Hmmm, I hadn't heard of Pyodide, and have not looked at the pyp5js source code. It looks like this is taking a totally different approach from what I am doing here.

The hardest part about py5's imported mode was getting the dynamic variables like mouse_x and mouse_y to work correctly. The py5 kernel is identical to the regular Python kernel except it does an AST transformation before executing the byte code. It took many iterations before I arrived at something that worked.

Also, do you think we could manage a Google Collaboratory notebook or a http://MyBinder.org link with the environment ready for teaching?

This is at the top of my priority list. Stay tuned...

That was easy:

https://github.com/hx2A/py5examples
https://mybinder.org/v2/gh/hx2A/py5examples/HEAD?urlpath=lab

Over the past week my coding efforts all related to running py5 online through mybinder or JupyterHub. I found and fixed a critical bug and made some enhancements that will greatly improve the usefulness of this.

I'll do another release by this weekend and create some worthwhile example code for the py5examples repo.

woderful!

@villares , when you have a moment, run this notebook through mybinder:

https://mybinder.org/v2/gh/hx2A/py5examples/HEAD?filepath=examples%2FRotating%20Cube.ipynb

It is using a dev version of py5. Turns out I won't be around this weekend, but I'll do a release next week for sure.

Also, I just emailed some Processing Foundation people about how to introduce py5 to the larger community.

Very nice!
