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

require 'uri'

require_relative '../../puppet/forge'

class Puppet::Forge
  # = Cache
  #
  # Provides methods for reading files from local 
    
    def retrieve(url)
      (path + File.basename(url.to_s)).tap do |cached_file|
        uri = url.is_a?(::URI) ? url : ::URI.parse(url)
        unless cached_file.file?
          if uri.scheme == 'file'
            # CGI.unescape butchers Uris that are escaped properly
            FileUtils.cp(Puppet::Util.uri_unescape(uri.path), cached_file)
          else
            # TODO: Handle HTTPS; probably should use repository.contact
            data = read_retrieve(uri)
            cached_file.open('wb') { |f| f.write data }
          end
        end
