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: help.rb
    path of file: ./repos/jets/lib/jets/command
    
    the code of the file until where you have to start completion: module Jets::Command
  class Help
 
    
      def text(namespaced_command)
        file = namespaced_command.to_s.gsub(':','/')
        path = File.expand_path("../help/#{file}.md", __FILE__)
        return IO.read(path) if File.exist?(path)

        # Also look up for a help folder within the current command folder
        called_from = caller.first.split(':').first
        unnamespaced_command = namespaced_command.to_s.split(':').last
        path = File.expand_path("../help/#{unnamespaced_command}.md", called_from)
        return IO.read(path) if File.exist?(path)
      end
