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: blockquote_fence_filter.rb
    path of file: ./repos/gitlabhq/lib/banzai/filter
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# NOTE: This is now a legacy filter, and is only used with the Ruby parser.
# The current markdown parser now properly handles multiline block quotes.
# The Ruby parser is now only for benchmarking purposes.
module Banzai
  module Filter
    
      def call_with_timeout
        return @text if MarkdownFilter.glfm_markdown?(context)

        @text.gsub(REGEX) do
          if $~[:blockquote]
            # keep the same number of source lines/positions by replacing the
            # fence lines with newlines
            indent = $~[:indent]
            "\n" + $~[:blockquote].gsub(/^#{Regexp.quote(indent)}/, "#{indent}> ").gsub(/^> $/, ">") + "\n"
          else
            $~[0]
          end
        end
