Richly rendered command line interfaces in click.

rich-click is a shim around Click that renders help output nicely using Rich.

Click is a "Python package for creating beautiful command line interfaces".
Rich is a "Python library for rich text and beautiful formatting in the terminal".

The intention of rich-click is to provide attractive help output from Click, formatted with Rich, with minimal customisation required.

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()

More complex example¶

rich-click has a ton of customisation options that let you compose help text however you'd like. Below is a more complex example of what rich-click is capable of:

Usage¶

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! ✨ Then continue to use Click as you would normally.

See examples/01_simple.py for 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.py for 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]
