timeout option for every input methods

[ajay15283]

Hi,

inquirer doesn't seems to have timeout option for text, list and checkbox. If a timeout option is added it can help to exit the program if a user didn't provide the input on mentioned time

Thanks

Hi Ajay,

You could always create your own wrapper around inquirer something like this:

import signal
import inquirer

def prompt_for(prompt: str, choice_options: list, default: str = None, timeout: int = None) -> str:
    """
    Prompt for choices from a user
    """

    if timeout:
        prompt = f'{prompt} ({timeout} seconds to decide)'
    if default:
        questions = [
            inquirer.List(
                "answer",
                message=prompt,
                choices=choice_options,
                default=default
            ),
        ]
    else:
        questions = [
            inquirer.List(
                "answer",
                message=prompt,
                choices=choice_options,
            ),
        ]

    def alarm_handler(signum, frame):
        raise TimeoutError()

    if timeout:
        signal.signal(signal.SIGALRM, alarm_handler)
        signal.alarm(timeout)
    try:
        return inquirer.prompt(questions)
    except TimeoutError:
            return default
    finally:
        signal.alarm(0)
