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: markdown.rb
    path of file: ./repos/runbook/lib/runbook/views
    
    the code of the file until where you have to start completion: module Runbook::Views
  module Markdown
    include Runbook::View
    extend Runbook::Helpers::FormatHelper
    extend Runbook::Helpers::SSHKitHelper

    def self.runbook__entities__book(object, output, metadata)
      output << "# #{object.title}\n\n"
    end

    def self.runbook__entities__section(object, output, metadata)
      heading = "#"*metadata[:depth]
      output << "#{heading} #{metadata[:index]+1}. #{object.title}\n\n"
    end

    def self.runboo
    
    def self.runbook__statements__assert(object, output, metadata)
      output << "   run: `#{object.cmd}` every #{object.interval} seconds until it returns 0\n\n"
      if object.timeout > 0 || object.attempts > 0
        timeout_msg = object.timeout > 0 ? "#{object.timeout} second(s)" : nil
        attempts_msg = object.attempts > 0 ? "#{object.attempts} attempts" : nil
        abort_msg = "after #{[timeout_msg, attempts_msg].compact.join(" or ")}, abort..."
        output << "   #{abort_msg}\n\n"
        if object.abort_statement
          object.abort_statement.render(self, output, metadata.dup)
        end
