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: git.rb
    path of file: ./repos/appraisal/lib/appraisal
    
    the code of the file until where you have to start completion: require "appraisal/bundler_dsl"
require 'appraisal/utils'

module Appraisal
  class Git < BundlerDSL
    def initialize(source, options = {})
      super()
      @source = source
      @options = options
    end

    def to_s
      if @options.empty?
        "git #{Utils.prefix_path(@source).inspect} do\n#{indent(super)}\nend"
      else
        "git #{Utils.prefix_path(@source).inspect}, #{Utils.format_string(@options)} do\n" +
          "#{indent(super)}\nend"
      end
    end
