[BUG] typer.main.get_group should return a click.Group

[dbanty]

Describe the bug

The function typer.main.get_group is annotated as returning a click.Command which isn't wrong because a click.Group is a click.Command, but means I have to cast to group when trying to integrate with existing Click applications.

To Reproduce

Steps to reproduce the behavior with a minimum self-contained file.

Replace each part with your own scenario:

• Create a file main.py with:

import typer

app = typer.Typer()


@app.callback()
def callback():
    """ My partially-upgraded-to-Typer app """

# insert some fancy new Typer commands here


click_group = typer.main.get_group(app)


@click_group.command()
def some_old_click_function():
      """ I need to rewrite this somday """

Run mypy on this script with mypy main.py and it will output something like

main.py:16: error: "Command" has no attribute "command"

Expected behavior

Able to drop in Typer at the top level to start slowly converting an existing Click app.

Screenshots

If applicable, add screenshots to help explain your problem.

Environment

• OS: macOS
• Typer Version: 0.2.1
• Python version: 3.8.2
• mypy version: 0.770
