[QUESTION] eagerness to mimic click.option ?

Hi, Is there a way to have a --version-type eager option with required Arguments? That is, the arguments are required unless you're just calling --version.

I got your code fragment to work if I declared version like this:

import typer

app = typer.Typer()

def print_version(ctx, param, value):
    if not value:
        return
    typer.echo("Version MM.mm.pp")
    raise typer.Exit()

@app.command()
def main(version: bool = typer.Option(False, "--version", "-v", is_eager=True, callback=print_version):
    print("foobar")

To be honest, I was hoping that Typer() would pass through the click.version_option(VERSION) decorator. This works but feels awkward.

yep that's the 1st thing I tried but so far didn't manage it
this solution works indeed but you need to type app main --version while on click app --version would make it,
there might be a way !

Thanks for the discussion @euri10 and @JnyJny !

I just added docs about --version with is_eager: https://typer.tiangolo.com/tutorial/options/version/

@randallpittman probably better to ask in a new issue following the template. 🤓

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I'm checking each one in order.
