cmd2.styles

Defines custom Rich styles and their corresponding names for cmd2.

This module provides a centralized and discoverable way to manage Rich styles used within the cmd2 framework. It defines a StrEnum for style names and a dictionary that maps these names to their default style objects.

Notes

Cmd2 uses Rich for its terminal output, and while this module defines a set of cmd2-specific styles, it's important to understand that these aren't the only styles that can appear. Components like Rich tracebacks and the rich-argparse library, which cmd2 uses for its help output, also apply their own built-in styles. Additionally, app developers may use other Rich objects that have their own default styles.

For a complete theming experience, you can create a custom theme that includes styles from Rich and rich-argparse. The cmd2.theme.update_theme() function automatically updates rich-argparse's styles with any custom styles provided in your theme dictionary, so you don't have to modify them directly.

You can find Rich's default styles in the rich.default_styles module. For rich-argparse, the style names are defined in the rich_argparse.RichHelpFormatter.styles dictionary.
