Choose kernel

[Eloitor]

In a jupyter notebook it is possible to choose other kernels (like SageMath).

Is it possible to choose the kernel in saturn?

There is no concept of kernels in Saturn. The idea is not to take over the environment, but to be just another Python module, inside whatever (possibly virtual) environment you like, that plays nice with everything else. So it's possible to install saturn as a package inside sage. The following works:

sage --pip install saturn_notebook
sage --python -m saturn_notebook

>>> from sage.all import *
>>> u = var('u')

Unfortunately, I don't know enough about sage to know if this will create problems or work as intended.

Thanks for the answer.

SageMath has slightly different syntax to python's: https://doc.sagemath.org/html/en/tutorial/afterword.html
The equivalent of eval in sage is from sage.misc.sage_eval import sage_eval.

I think it should be possible to replace the python's eval of the notebook with sage_eval, but I'm not sure how

All the code evaluation logic happens in evaluate.py. Perhaps, there is a way to tweak that. If you find a clean way, please submit a pull request.

Maybe https://pypi.org/project/jupyter-client/ could be used...

Here's an example of a jupyter notebook app using it: https://github.com/cvfosammmm/Porto/blob/master/notebook/backend/backend_code.py#L209
