--- **rich-click** is a shim around [Click](https://click.palletsprojects.com/) that renders help output nicely using [Rich](https://github.com/Textualize/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. ## Features - 🌈 Rich command-line formatting of click help and error messages - 😌 Same API as Click: usage is simply `import rich_click as click` - 💫 Nice styles by default - 💻 CLI tool to run on _other people's_ tools (prefix the command with `rich-click`) - 📦 Export help text as HTML or SVG - 🎁 Group commands and options into named panels - ❌ Well formatted error messages - 🔢 Easily give custom sort order for options and commands - 🎨 Extensive customisation of styling and behaviour possible ## Installation ```shell pip install rich-click ``` [Read the docs](https://ewels.github.io/rich-click#installation) for all supported installation methods. ## Examples ### Simple Example To use rich-click in your code, replace `import click` with `import rich_click as click` in your existing click CLI: ```python 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() ``` ![`python examples/11_hello.py --help`](docs/images/hello.svg) _Screenshot from [`examples/11_hello.py`](examples/11_hello.py)_ ### More complex example ![`python examples/03_groups_sorting.py`](docs/images/command_groups.svg) _Screenshot from [`examples/03_groups_sorting.py`](examples/03_groups_sorting.py)_ ## Usage This is a quick overview of how to use **rich-click**. [Read the docs](https://ewels.github.io/rich-click) 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: ```python import rich_click as click ``` That's it! ✨ Then continue to use Click as you would normally. > See [`examples/01_simple.py`](https://github.com/ewels/rich-click/blob/main/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. ```python 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`](https://github.com/ewels/rich-click/blob/main/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: ```console $ rich-click awesometool --help Usage: awesometool [OPTIONS] ..more richified output below.. ``` ## License This project is licensed under the MIT license.
