NeoVim - Interact with the thing that pop ups when you type in a command

Question

Questions

• How can I type something in there?
• What even is the name of this thing?

Problem

If you type in for example

:!echo 'Hello World'

This kinda terminal thing pops up

I want to interact with it instead of it going away after the first key press. Example:

:!python3 -c 'input("Type a Number:")'

From the command above I get an Error.

I don't want to use the :terminal or any work arounds, I just want to know if this is possible^^

Thanks for your help :)

Answer 1

There is a big difference between Vim and NeoVim when it comes to :!: the former runs the command in a shell-like environment, with stdin/stdout connected to the (p)TTY. The latter runs the subprocess in a "non-interactive" environment: essentially, no input is possible.

In both Vims you can use :terminal to have full interactivity; in NeoVim, this is the only builtin option.
