gradient example

This library is a wrapper of the great rich library that extends rich.text.Text to allow for the easy generation gradient text from either user entered colors or randomly if no colors are entered.

Borrowing from pydantic-extra-types' Color class As of v0.3.0, rich-gradient removed the color logic from rich-gradient and created rich-color-ext

  • 3 or 6 digit hex code (e.g. #f00 or #ff0000)
  • RGB color codes (e.g. rgb(255, 0, 0))
  • RGB tuples (e.g. (255, 0, 0))
  • CSS3 Color Names (e.g. red)

Installation

uv (Recommended)

uv add rich-gradient

Pip

pip install rich-gradient

CLI Usage

The package ships with a Typer-based CLI. The first command is text, which prints gradient-styled text. More commands may be added over time.

Quick examples

  • Print gradient text with two color stops:

    rich-gradient text "Hello [b]world[/b]!" -c magenta -c cyan

  • Rainbow gradient (auto-generated colors):

    rich-gradient text "Rainbow!" --rainbow

  • Read from stdin:

    echo "From stdin" | rich-gradient text

  • Wrap in a panel with a title:

    rich-gradient text "Panel content" --panel --title "Gradient Panel"

  • Save to SVG (uses the project terminal theme):

    rich-gradient text "Save me" --save-svg out/example.svg

Common options

  • -c/--color: Repeat to add multiple foreground color stops.
  • -b/--bgcolor: Repeat for background color stops.
  • --rainbow, --hues: Auto-generate a palette if colors aren’t provided.
  • --style, --justify, --overflow, --no-wrap/--wrap, --end, --tab-size, --markup/--no-markup.
  • --panel, --title: Wrap output in a panel with optional title.
  • --width: Console width. --record: enable recording.
  • --save-svg PATH: Save the current render as SVG.

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!"))

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:

3 or 6 digit hex colors, rgb/rgba colors, and CSS3 Named Colors

Example Code

Specific Two-Color Gradient Example

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

Two Color Gradient


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

multi-color specific colors


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"
    )
)

Rainbow Gradient

*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()

Still Text
