Ruby Ombre

Ombre provides gradients for your terminal between any number of RGB values.

Features

• Horizontal, vertical, and diagonal gradients for any number of colors.

True Color Support

This will only look good on terminals that support 24bit colors, for now.

Setup

Add to Gemfile:

gem 'ombre'

and run bundle install.

In Ruby do:

require 'ombre'

Usage

There are four main functions available for Ombre:

# colors in the below functions should be an array of 24 bit hexidecimal RGB values as strings.

# Returns the block of text marked up with colors to create a horizontal gradient from left to right
Ombre.horizontal(text, colors)
Ombre.horizontal("############\n#          #\n# Horiz. ###\n# Ombre ####\n# Test #####\n# From #####\n# Red ######\n# To #######\n# Blue #####\n#          #\n############", ["FF0000", "0000FF"])

# Returns the block of text marked up with colors to create a vertical gradient from top to bottom
Ombre.vertical(text, colors)
Ombre.vertical("############\n#          #\n# Vertical #\n# Ombre ####\n# Test #####\n# From #####\n# Red ######\n# To #######\n# Blue #####\n#          #\n############", ["FF0000", "0000FF"])

# Returns the block of text marked up with colors to create a diagonal gradient from top-left to bottom-right
Ombre.diagonal(text, colors)
Ombre.diagonal("############\n#          #\n# Diagonal #\n# Ombre ####\n# Test #####\n# From #####\n# Red ######\n# To #######\n# Blue #####\n#          #\n############", ["FF0000", "0000FF"])

# Returns the block of text marked up with colors to create a diagonal gradient from bottom-left to top-right
Ombre.diagonal_up(text, colors)
Ombre.diagonal_up("############\n#          #\n# Diagonal #\n# Ombre ####\n# Test #####\n# From #####\n# Red ######\n# To #######\n# Blue #####\n#          #\n############", ["FF0000", "0000FF"])
