Terminal.ipynb not working in Panelite: Cannot run subprocesses

[MarcSkovMadsen]

Panelite=0.14.3

I'm trying the notebook reference/widgets/Terminal.ipynb. I can see that the command terminal.subprocess.run fails with errors. This is probably expected and not something that can be fixed.

ImportError: cannot import name 'tcgetattr' from 'tty' (/lib/python3.10/tty.py)

 File "/lib/python3.10/site-packages/panel/widgets/terminal.py", line 144, in _set_winsize
    fcntl.ioctl(self._fd, termios.TIOCSWINSZ, winsize)
AttributeError: module 'fcntl' has no attribute 'ioctl'

This will likely never work. Not sure what you suggest, I'd probably just not include the reference example on panelite.

My thoughts is that with the work I do we know about issues in notebooks. So we can include a new first Markdown cell explaining that

• Panelite is young and experimental. Please report issues on Github.
• This notebook has known issues Terminal.ipynb not working in Panelite: Cannot run subprocesses #4407, ...

For example the HoloViews reference notebook does not work either. But here the issue will probably be fixed one day.

Parts of the Terminal notebook is useful - also on Panelite. And its the only documentation we have.

I believe that as soon as we have cleaned up biggest Panelite issues we should link to Panelite instead of Binder. It would be a huge improvement.

Agree with that plan of action but for this particular instance I would not open an issue because it's something that can't be fixed.

i.e. the message should just say subprocesses not supported in a browser.
