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: display_invalid_blocks.rb
    path of file: ./repos/syntax_suggest/lib/syntax_suggest
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative "capture_code_cont
    
    def call
      if document_ok?
        return self
      end

      if filename
        @io.puts("--> #{filename}")
        @io.puts
      end
