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: ruby_repl.rb
    path of file: ./repos/boxcars/lib/boxcars
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Boxcars
  # used by Boxcars to run ruby code
  class RubyREPL
    # Execute ruby code
    # @param code [String] The code to run
    def call(code:)
      Boxcars.debug "RubyREPL: #{code}", :yellow

      # wrap the code in an exception block so we can catch errors
   
    
    def call(code:)
      Boxcars.debug "RubyREPL: #{code}", :yellow

      # wrap the code in an exception block so we can catch errors
      wrapped = "begin\n#{code}\nrescue Exception => e\n  puts 'Error: ' + e.message\nend"
      output = ""
      IO.popen("ruby", "r+") do |io|
        io.puts wrapped
        io.close_write
        output = io.read
      end
      if output =~ /^Error: /
        Boxcars.debug output, :red
        Result.from_error(output, code: code)
      elsif output.blank?
        Result.from_error("The code you gave me did not print a result", code: code)
      else
        output = ::Regexp.last_match(1) if output =~ /^\s*Answer:\s*(.*)$/m
        Boxcars.debug "Answer: #{output}", :yellow, style: :bold
        Result.from_text(output, code: code)
      end
