Example Code

import typer

app = typer.Typer()

# library code
@app.callback()
def callback(path: Path) -> None:
    print("callback")
    ... # do some setup with global config


# somewhere else
@app.callback()
def callback2(more_arguments: str) -> None:
    print("callback2")
    # do something more with config

@app.command()
def hello() -> None:
    print("Hi!")

if __name__ == "__main__":
    app()

Description

My use-case is that I want to create a library with implemented basic CLI, and a user can then add additional options that are written to some global object. So basically I just want to add additional options to callback, without rewriting previous arguments.
