Githug - level up your Git chops

We’ve blogged about Git gamification before. Now, Gary Rennie has released Githug which challenges players to complete levels and learn Git features at the same time. Levels are created using a Ruby-based DSL:

difficulty 1
description "There is a file in your folder called README, you should add it to your staging area"

setup do
  repo.init
  FileUtils.touch("README")
end

solution do
  return false unless repo.status.files.keys.include?("README")
  return false if repo.status.files["README"].untracked
  true
end

hint do
  puts "You can type `git` in your shell to get a list of available git commands"
end
