Jupyter kernel always dies and restarts for any mcall(MExpr("xxx"))

[sunnsi]

I am trying to use the package in jupyter.
The package can be successfully loaded by using "using Maxima".
However, any maxima operation will lead to jupyter kernel dying and then restating.
For example: m"diff(sin(x))" and mcall(m"plot(sin(x),[x,-30,30])")

Thanks for reporting this. It seems that Latex display is broken. Things like
trigsimp(:(sin(x)^2 + cos(x)^2))
still work as they return a Julia expression, but anything that returns a Maxima expression (MExpr) will try to use the Latex display and kill the kernel. Perhaps the method to do this has changed in IJulia...

A bit more information:

This just seems to hang forever in JupyterLab. Also, I can confirm that Maxima code for displaying latex is still working as expected so something must have moved upsteam. I'll file an issue there.

In the near-term, it appears that display("text/latex", m::MExpr) is still working so you could switch to that while I work on this. For example, instead of

m"sin(x)/x"

at the end of your Jupyter cell, use

display("text/latex", m"sin(x)/x")
