handling implicit prompt request in run time like colab

在 JupyterLab 中使用 !touch something.txt，然后使用 !rm -i something.txt 重现该行为，接着阅读链接的 JupyterLab issue #8522 以了解相关上下文。完成的标准是：通过 magic 命令或原生支持，让隐式运行时提示显示给用户，同时不让内核单元格无限期地保持运行状态。

I've recently encountered this problem that when my code has an implicit user input request, the Jupiter notebook isn't able to handle it and the kernel just keeps running until I manually interrupt it. If I explicitly use an input or read command the kernel will ask me for user input while running in a cell and the problem is for command requiring input without asking explicitly.

The google colab can handles such a situation without any problem and I'm asking for a magic command to do the same in Jupiter notebook and jlab. consider the following example which doesn't have any explicit input or read function associated with it:

!touch something.txt
!rm -i something.txt

If I run this code in colab, a prompt will come up and ask me if I want to delete something.txt. However, if I run the same code in jlab, the kernel keeps running in that cell and I get no prompt or any other output until I interrupt the kernel manually!!

• So, this is a feature request for a new magic command or native support to watch for implicit input requests in run time, similar to what colab does natively without any magic.
