drawille-cr

Build Status

Based on the the drawille library for Python, this library allows the developer to draw using Unicode braille symbols in the terminal.

Earth Rotation

Notes

The library extends drawille to support RGB colors in the terminal. It doesn't attempt to degrade gracefully to terminals that don't support RGB. This library is very much a work in progress. If there's functionality in it that you wish to see, please feel free to fork or submit a pull request.

Usage

require "drawille-cr"

c = Drawille::Canvas.new

(0..180).each do |x|
  c.set(x, (10 + Math.sin(x * 2 / Math::PI * 10) * 10).to_i32)
end

print c.render

Basic Example

See examples for more info on how to use, or read the implementation.
