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: operating_system_parser.rb
    path of file: ./repos/foreman/app/services/foreman_ansible
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ForemanAnsible
  # Methods to parse facts related to the OS
  module OperatingSystemParser
    def operatingsystem
      args = { :name => os_name, :major => os_major, :minor => os_minor }
      args[:release_name] = os_release_name if os_name == 'Debian' || os_name == 'Ubuntu'
      # for Ansible, the CentOS Stream can be identified by missing minor version only
      args[:name] = "CentOS_Stream" if os_name == 'Cen
    
    def os_name
      if facts[:ansible_os_family] == 'Windows'
        windows_os_name.tr(" \n\t", '')
      else
        # RHEL 7 is marked as either RedHatEnterpriseServer or RedHatEnterpriseWorkstation, RHEL 8 is lsb id is RedHatEnterprise
        # but we always consider it just RHEL on this level, workstation is differentiated below
        distribution = facts[:ansible_lsb].try(:[], 'id') || facts[:ansible_distribution]

        case distribution
        when 'RedHatEnterprise', 'RedHatEnterpriseServer'
          distribution = 'RedHat'
        when 'RedHatEnterpriseWorkstation'
          distribution = 'RedHat_Workstation'
        end
