Examples
Simple Example
To use rich-click in your code, replace import click with import rich_click as click in your existing click CLI:
import rich_click as click
@click.command()
@click.option("--count", default=1, help="Number of greetings.")
@click.option("--name", prompt="Your name", help="The person to greet.")
def hello(count, name):
"""Simple program that greets NAME for a total of COUNT times."""
for _ in range(count):
click.echo(f"Hello, {name}!")
if __name__ == '__main__':
hello()
Screenshot from examples/11_hello.py
More complex example
rich-click has a ton of customization options that let you compose help text however you'd like.
Below is a more complex example of what rich-click is capable of, utilizing themes and panels:

Usage
This is a quick overview of how to use rich-click. Read the docs for more information.
There are a couple of ways to begin using rich-click:
Import rich_click as click
Switch out your normal click import with rich_click, using the same namespace:
import rich_click as click
That's it! โจ Then continue to use Click as you would normally.
See
examples/01_simple.pyfor an example.
Declarative
If you prefer, you can use RichGroup or RichCommand with the cls argument in your click usage instead.
This means that you can continue to use the unmodified click package in parallel.
import click
from rich_click import RichCommand
@click.command(cls=RichCommand)
def main():
"""My amazing tool does all the things."""
See
examples/02_declarative.pyfor an example.
rich-click CLI tool
rich-click comes with a CLI tool that allows you to format the Click help output from any package that uses Click.
To use, prefix rich-click to your normal command.
For example, to get richified Click help text from a package called awesometool, you could run:
$ rich-click awesometool --help
Usage: awesometool [OPTIONS]
