rich-gradient 0.3.9

A gradient generator for the Rich library.

Purpose

rich-gradient layers smooth foreground and background gradients on top of Rich renderables. It includes a drop-in Text subclass, wrappers for Panel and Rule, utilities for building palettes, and a rich-click (Click) CLI for trying gradients from the terminal.

Highlights

• Works anywhere Rich expects a ConsoleRenderable, including panels, tables, and live updates.
• Generates color stops automatically or from CSS color names, hex codes, RGB tuples, or rich.color.Color objects.
• Supports foreground and background gradients, rainbow palettes, and deterministic color spectrums.
• Ships with ready-to-use renderables:
  • Text
  • Gradient
  • Panel
• Rule
• Spectrum
• And their animated counterparts.
• Includes a CLI for quick experiments and SVG export for documentation or asset generation.
• Auto-bootstraps a configuration file (~/.rich-gradient) where you can toggle animation globally and customise the default spectrum palette.

What's new in v0.3.9

• CLI docs now reflect the Click + rich-click commands (print, panel, rule, markdown) with up-to-date options and examples.
• Help text across CLI options uses the rich markup styling from text_command.py for consistency.
• Tests run without an editable install because tests/conftest.py prepends src/ to sys.path.
• Docs CSS forces the page background to the theme color to eliminate the black/transparent flash at the top of pages.

Installation

rich-gradient targets Python 3.10+.

uv

# Recommended: use uv

CLI Usage

The CLI is built with Click + rich-click. Subcommands:

• print: gradient text. Options: --colors/-c, --bgcolors, --rainbow, --hues, --style, --justify, --overflow, --no-wrap, --end.
• rule: gradient rule. Options: --title, --title-style, --colors, --bgcolors, --rainbow, --hues, --thickness, --align, --end.
• panel: gradient panel. Options: --colors, --bgcolors, --rainbow, --hues, --title, --title-style, --title-align, --subtitle, --subtitle-style, --subtitle-align, --style, --border-style, --padding, --vertical-justify, --text-justify, --justify, --expand/--no-expand, --width, --height, --box, --end, --animate, --duration.
• markdown: gradient markdown. Options: --colors, --bgcolors, --rainbow, --hues, --style, --justify, --vertical-justify, --overflow, --no-wrap, --end, --animate, --duration.

Quick examples:

• Gradient text: rich-gradient print "Hello [b]world[/b]!" -c magenta,cyan
• Rainbow text: rich-gradient print "Rainbow!" --rainbow
• Panel with title: rich-gradient panel "Panel content" -c red,blue --title "Gradient Panel"
• Rule with title: rich-gradient rule --title "Section" -c "#f00,#0ff"
• Gradient markdown: rich-gradient markdown "# Title" --colors "#ff0,#0ff" --justify center

Contributor notes

• Tests: pytest works without an editable install because tests/conftest.py adds src/ to sys.path. No extra env tweaks needed; just install deps and run pytest.

Usage

Basic Gradient Text Example

To print a simple gradient just substitute the Gradient class for the Text class in the rich-gradient library.

from rich.console import Console
from rich_gradient import Gradient

console = Console()
console.print(Gradient("Hello, World!"))

Gradient Text with Specific Colors

If you want a bit more control of the gradient, you can specify the colors you want to use in the gradient by passing them as a list of colors to the colors parameter.

Color Formats

Color can be parsed from a variety of formats including:

Example Code

Specific Two-Color Gradient Example

console.print(
    Text(
        "This a gradient with two colors.",
        colors=["red", "orange"]
    ),
    justify="center"
)

---

Specific Four-Color Gradient Example

console.print(
    Text(
        "This a gradient uses four specific colors.",
        colors=["red", "#ff9900", "#ff0", "Lime"],
        justify="center"
    )
)

Specific Color Gradient Result

---

Rainbow Gradient Example

If four colors isn't enough, you can use the 'rainbow' parameter to generate a rainbow gradient that spans the entire spectrum of colors randomly.

console.print(
    Text(
        "This is a rainbow gradient.",
        rainbow=True,
        justify="center"
    )
)

*The rainbow gradient is generated randomly each time the code is run.

---

Still inherits from rich.text.Text

Since Gradient is a subclass of Text, you can still use all the same methods and properties as you would with Text.

console.print(
    Gradient(
        "This is an underlined rainbow gradient.",
        rainbow=True,
        style="underline"
    ),
    justify="center"
)
console.line()
console.print(
    Gradient(
        "This is a bold italic gradient.",
        style="bold italic"
    ),
    justify="center"
)
console.line()
