A simple anyio-compatible fork of Click, for powerful command line utilities.

Project description

What’s AsyncClick?

AsyncClick ist a fork of Click that works well with trio, asyncio, or curio.

Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It’s the “Command Line Interface Creation Kit”. It’s highly configurable but comes with sensible defaults out of the box.

It aims to make the process of writing command line tools quick and fun while also preventing any frustration caused by the inability to implement an intended CLI API.

AsyncClick in four points:

  • Arbitrary nesting of commands

  • Automatic help page generation

  • Supports lazy loading of subcommands at runtime

  • Seamlessly use async-enabled command and subcommand handlers

Installing

Install and update using pip:

$ pip install asyncclick

AsyncClick supports Python 3.6 and newer, and PyPy3.

A Simple Example

import anyio
import asyncclick as click

@click.command()
@click.option("--count", default=1, help="Number of greetings.")
@click.option("--name", prompt="Your name", help="The person to greet.")
async def hello(count, name):
    """Simple program that greets NAME for a total of COUNT times."""
    for _ in range(count):
        if x: await anyio.sleep(0.1)
        click.echo(f"Hello, {name}!")

if __name__ == '__main__':
    hello(_anyio_backend="trio")  # or asyncio, or curio
$ python hello.py --count=3
Your name: Click
Hello, Click!
