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: pubsub.rb
    path of file: ./repos/souls/lib/souls/cli/sync
    
    the code of the file until where you have to start completion: module SOULs
  
    
    def pubsub
      project_id = SOULs.configuration.project_id
      worker_name = FileUtils.pwd.split("/").last

      unless worker_name.match(/^worker-(\d|\w)+(-)*(\d|\w)+$/)
        SOULs::Painter.error("You are at wrong dir!\nPlease go to worker-* dir!")
        return false
      end
