Ctrl-z in nushell sends the terminal into an unusable state.

[cyanic-selkie]

Summary

Nushell doesn't have moving processes to background/foreground implemented yet and therefore Ctrl-z shouldn't do anything - this is how other software I tried behaves.

However, helix seemingly "exits" and leaves the terminal in an unusable state. Furthermore, killing the terminal leaves the helix process running in the background.

I tried testing this on alacritty with both nushell and bash. Everything works as expected in bash where background/foreground is implemented.

Reproduction Steps

I tried this:

1. nu
2. hx
3. Ctrl-z

I expected this to happen:
Nothing.

Instead, this happened:
Helix seemingly "exited" and left the terminal in an unusable state. Killing the terminal left the helix process running in the background.

This might be fixed by #3322 or #3546

Could you try suspending from nushell with either of those?

[cyanic-selkie]

Indeed, #3322 works. Hitting Ctrl-Z triggers the following message in the statusline: "Suspend is not supported by this terminal."

#3546 has no effect.

Ah, seems like nushell has the same suspend behavior as elvish then. Let's close this in favor of #3321
