@joannfeng This is called continuous integration, basically a web service that takes the code and run tests for every push event on github.

It worked before but not now, perhaps you can compare the log messages and check what is going on, and try to fix .travis.yml file.

You can create a branch and push your changes to .travis.yml there until the tests pass.

https://github.com/vatlab/sos-javascript/blob/master/test/test_data_exchange.py is not completed yet. We will need to go through each datatypes and make sure they work as expected.

Currently, %get and %put magics create outputs with the value of the variables being passed.
Under some circumstances (passwords, or just long very values) this might not be the desired behavior.

Small example below:

Is there a way to suppress this output?
I have tried playing around with the %capture magic (which seems to be the standard way to suppress outputs in a notebook) but with no luck.

TypeScript was not supported because of itypescript depends on Python 2.x. I have just tried and confirmed that this kernel now supports Python 3.x and I can load the kernel without problem. We should add support to TypeScript.

Hi!

We've updated our jupyterlab/sos installation with the following module versions:

jupyterlab                    3.6.5
jupyterlab-sos                0.9.0
sos                           0.24.1
sos-bash                      0.21.0
sos-javascript                0.20.0
sos-matlab                    0.20.2
sos-notebook                  0.24.2
sos-papermill                 0.2.1
sos-python                    0.20.0
sos-r                         0.20.1

... and we have notice one blocking issue.

This cell:

%use SoS
%put my_var --to JavaScript

gives the following warning:

/opt/jlab-env/lib/python3.11/site-packages/sos_notebook/kernel.py:837: RuntimeWarning: coroutine 'sos_JavaScript.get_vars' was never awaited
  get_vars_func(items)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback 

and my_vars is not exported back to the Javascript subkernel (transfer from JavaScript to SoS works).

I changed the file sos_javascript/kernel.py and removed the async keyword in front of the get_vars(...) method and now it works (i.e. no more warning and variable is transferred).

However, I am not sure about this change, since sos_r/kernel.py also has an async get_vars(...) and I don't see any warning when using it.

What's the proper way of fixing this?

Thank you for the great work. We've been using SoS to teach image processing laboratory sessions with JupyterLab, and it has been a life-saver.

We are in the progress of updating our JupyterLab hub from v1 to v2. Currently, our production machines are in 1.2.18 and the staging platform is in 2.2.9. Both have the iJavascript kernel installed (5.2.0) and SoS working well between SoS and Javascript. However, for some reason I can not understand, in JupyterLab v2 JavaScript arrays seem to move to the SoS kernel only if they contain less than 2220 elements (see screenshots below).

A bit more information on the SoS packages in each machine.

sos==0.21.12
sos-bash==0.20.0

Staging machine (JupyterLab v2, weird limit in size of JS array)
