Can't quit from the jupyter console?

[nations-Xiong]

When I type quit();, it gives me a message like this:

[Condition of type JUPYTER:QUIT-CONDITION]

#<ENVIRONMENT {1006295BD3}>
   [Environment of thread #<THREAD "SHELL Thread" RUNNING {1005060213}>]

This is probably a bug in common-lisp-jupyter. I'll look into it.

You can also exit from the console with Ctrl+D usually.

I've tried. But Ctrl+D does not work either. The only to quit it is close the terminal.

[yitzchak]

Are you running the terminal from inside JupyterLab or via an actual terminal?

Actual terminal. The command I run: jupyter console --kernel=maxima

[yitzchak]

I have a potential fix in the works. Have to make some changes to common-lisp-jupyter also so it will not work until quicklisp updates unless you make put common-lisp-jupyter into local-projects.

[nations-Xiong]

@yitzchak So what should I do?

[yitzchak]

Submitted a PR. Once the PR is accepted you will need to either wait for quicklisp to update common-lisp-jupyter which is usually about once a month or clone yitzchak/common-lisp-jupyter into ~/quicklisp/local-projects

Thanks, Tarn. I've accepted the PR.
