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: up2date.rb
    path of file: ./repos/puppet/lib/puppet/provider/package
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

Puppet::Type.type(:package).provide :up2date, :parent => :rpm, :source => :rpm 
    
  def latest
    # up2date can only get a list of *all* available packages?
    output = up2date "--showall"

    if output =~ /^#{Regexp.escape @resource[:name]}-(\d+.*)\.\w+/
      Regexp.last_match(1)
    else
      # up2date didn't find updates, pretend the current
      # version is the latest
      @property_hash[:ensure]
    end
