If you use Mathematica mainly for graphics, Jupyter is not for you. A Jupyter interface is great for remote Kernels and Markdown/LaTeX, things that Mathematica does not support that well.

Regarding the black page, is it a problem of safari ? If the out.pdf is properly exported in the JWLout folder but safari does not open it, maybe safari is not well suited to work with Jupyter. As I mention in the description, JWLS is not much more than a couple of fifo on top of a bash_kernel.

That does not work: clicking the link opens a totally black page in Safari. I guess this needs some more work!

In any case, if it worked this does defeat some of the purpose of a Jupyter front end to the Wolfram Engine, namely, to have all output in the same (Jupyter) notebook as the input, and it is contrary to the expected behavior in Mathematica since many versions, where the output from a Plot, Plot3D, etc. is in effect the graphical display and the graphical display is not a side-effect. (That behavior was one of the great advances in the Mathematica Front End, where one no longer had to use the DisplayFunction option before combining several graphics in a single output.)

Hi Murray, thanks for your feedback. That is MacOS sed complaining about the use of ~ . A solution is to install gnu-sed: brew install gnu-sed and then replace "sed" with "gsed" at line 164 of kernel.py .
