Add way to exit go-prompt about go-prompt HOT 3 CLOSED

Hi @fhemberger!
Thank you for using kube-prompt.
The answer is Ctrl-D. But maybe it is a little hard to notice.

I'll consider the better way.

from go-prompt.

By implementing exit or quit command in go-prompt, it may be conflict with something features.
For example, kube-prompt supports kubectl exec command. By using this, we can login to the container managed by kubernetes like:

$ kube-prompt
>>> exec -it <pod name> bash  # login to the container.
bash-$ pwd
/home/foo
bash-$ exit  # logout
>>> 

In this pattern, the user just wanted to logout and the user doesn't want to quit kube-prompt. So now I think exit and quit command should be implemented in kube-prompt like:

func completer(d prompt.Document) []prompt.Suggest {
    // returns something suggestions.
}

func executor(in string) {
    if in == "exit" {
        // quit this program.
    }
    // execute something command.
    return
}

func main() {
    pt := prompt.New(executor, completer)
    pt.Run() 
}

from go-prompt.

I decided the go-prompt doesn't provide other way to exit and this problem on kube-prompt is fixed like:

Thanks.
