    # It would be better to use https instead of the git protocol, but this
    # can break deployment of existing locked bundles when switching between
    # different versions of Bundler. The change will be made in 2.0, which
    # does not guarantee compatibility with the 1.x series.
    #
    # See https://github.com/bundler/bundler/pull/2569 for discussion
    #
    # This can be overridden by adding this code to your Gemfiles:
    #
    #   git_source(:github) do |repo_name|
    #     repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
    #     "https://github.com/#{repo_name}.git"
    #   end
    repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
    "git://github.com/#{repo_name}.git"
  end
  git_source(:gist) {|repo_name| "https://gist.github.com/#{repo_name}.git" }
  git_source(:bitbucket) do |repo_name|
    user_name, repo_name = repo_name.split "/"
    repo_name ||= user_name
    "https://#{user_name}@bitbucket.org/#{user_name}/#{repo_name}.git"
  end
