no output from cell evaluation (using Python 3.5) #27

Closed dimpase closed 6 years ago

dimpase commented 6 years ago

I have installed Jupyter using pip3 install jupyter --user on 4.14.3-gentoo #3 SMP x86_64 Intel(R) and JupyterKernel as described in the manual (and all the needed packages, naturally).

I do not get any echo from commands in input cells, only if I do Print() then I get to see things. This is not how it is meant to work, right?

Also, if I do not complete a statement with ; then the echo from execution is a message on red background saying An error happened.

I also have the issue with statements not completed with ; . I see the gap error in the jupyter log 

Syntax error: ; expected in stream:1

but then no further communication with the kernel is possible.

Otherwise everything works perfectly (and is awesome)

Most of this is fixed in the master branch of JupyterKernel, though the current 4.9.1 GAP release has a bug that inconveniently crashes the kernel when a syntax error occurs.

I'm curious, is this fixed or part of an ongoing pull request? This is one of the issues we had with that kernel on cocalc.com and I want to know if we should try again.

dimpase commented 6 years ago

It would be good to know what GAP kernel bug this is. Thanks!

cmdawson commented 6 years ago

I believe it is this one
