auto-rich-argparse 0.1.0

Automatically use rich-argparse with argparse command line tools

auto-rich-argparse

Automatically use rich-argparse help formatters with argparse command line tools.

Usage

Install auto-rich-argparse in the same environment as your command line tool.

Try it out with your favorite tool using uvx --with auto-rich-argparse <YOUR_FAVORITE_TOOL> --help

Tools installed with pipx

If your tool is installed with pipx, use the pipx inject command to add auto-rich-argparse to the tool's environment. For example, to use rich-argparse with pre-commit:

pipx inject pre-commit auto-rich-argparse

Tools installed with uv tool

If your tool is installed with uv tool, use the --with flag to install auto-rich-argparse:

uv tool install pre-commit --with auto-rich-argparse

Tools in the current project

You can also install auto-rich-argparse in you project's environment and it will be used by all tools that use argparse in that environment:

python -m pip install auto-rich-argparse

How it works

auto-rich-argparse works by monkey patching the argparse.ArgumentParser class to use a subclass of RichHelpFormatter from rich-argparse instead of the default argparse.HelpFormatter. The formatter tries to be compatible with the tool's formatter by setting the following options:

FormatterClass.help_markup = False
FormatterClass.text_markup = False
FormatterClass.group_name_formatter = str

Known limitations

This doesn't currently work if the tool passes a function as the formatter_class argument to ArgumentParser instead of a class.
