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: muut.rb
    path of file: ./repos/discourse/script/import_scripts
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "csv"
require File.expand_path(File.dirname(__FILE__) + "/base.rb")

# Edit the constants and initialize method for your import data.

cl
    
  def repair_json(arg)
    arg.gsub!(/^\(/, "") # content of file is surround by ( )
    arg.gsub!(/\)$/, "")

    arg.gsub!(/\]\]$/, "]") # there can be an extra ] at the end

    arg.gsub!(/\}\{/, "},{") # missing commas sometimes!

    arg.gsub!("}]{", "},{") # surprise square brackets
    arg.gsub!("}[{", "},{") # :troll:

    arg
  end
