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: setup.rb
    path of file: ./repos/activerecord-jdbc-adapter/bench
    
    the code of the file until where you have to start completion: # frozen_string_literal: false

require 'benchmark/ips'

if ENV['RAILS']  # Use local clone of Rails
  rails_dir 
    
def do_profile_and_print_data(printer = :flat, &block)
  print_profile_data do_profile_data(&block), printer
end

def print_profile_data(data, printer = :flat)
  unless data
    return warn "no profile data to print"
  end
  if defined? JRUBY_VERSION
    printer = JRuby::Profiler.const_get(printer.to_s.capitalize) rescue JRuby::Profiler::FlatProfilePrinter
    printer.new(data).print_profile(STDOUT)
  end
