How to set the prog name of a group?

[anemele]

Hi, there.

argparse

I have a package xxx and use argparse to create a CLI, and use a batch script to call it.

In xxx/__main__ I can pass __package__ to prog to set the program name as xxx

  parser = argparse.ArgumentParser(prog=__package__, description=__doc__)

batch script xxx.bat

@echo off
setlocal
set PYTHONPATH=%~dp0;%PYTHONPATH%
call python -m %~n0 %*

argparse is not easy to use, so I migrate to click.

click

use click, I pass __package__ to name but it not works. (I don't know exactly what the parameter name is :)

@click.group(name=__package__)

I find click will auto detect the program name by _detect_program_name() at click/utils.py:523

Is it able to set by user?
