You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: babushka.rb
    path of file: ./repos/babushka/deps
    
    the code of the file until where you have to start completion: meta :babushka do
  def repo
    Babushka::GitRepo.new(path)
  end

  def qualified_ref
    # Prepend "origin/" if the resulting ref is valid, but not if the repo
    # doesn't exist yet. (We fetch before resolving remote refs, but that's
    # not possible before the repo exists.)
    if repo.exists? &
    
  def qualified_ref
    # Prepend "origin/" if the resulting ref is valid, but not if the repo
    # doesn't exist yet. (We fetch before resolving remote refs, but that's
    # not possible before the repo exists.)
    if repo.exists? && repo.all_branches.include?("origin/#{ref}")
      "origin/#{ref}"
    else
      ref
    end
  end
