Isacc-rb is FREE and OPEN SOURCE ruby gem for drawing in terminal.

Install the gem and add to the application's Gemfile by executing:

$ bundle add isaac-rb

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install isaac-rb

require_relative "lib/isaac/canvas"
canvas = Isaac::Canvas.new(5, 5)
250.times do |y|
  x = y % 25
  canvas.clear
  canvas.draw_pixel(x / 5, x % 5, "#", Isaac::Color::RED)
  canvas.display
  sleep 0.1
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

Everyone interacting in the Isaac project's codebases, issue trackers, chat rooms and mailing lists is expected to follow the code of conduct.
