I guess I was punk once.

thechangelog:

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

Got an idea for a Githug level? Submit a patch.
