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: source_map_helper.rb
    path of file: ./repos/opal/spec/support
    
    the code of the file until where you have to start completion: module SourceMapHelper
  extend self

  # Just for debugging purposes
  def inspect_source(source)
    puts source_with_lines(source)
  end

  # Just for debugging purposes
  def source_with_lines(source)
    source.split("\n", -1).map.with_index { |line, index| "#{(index).to_s.rjust(3)} | #{line}" }.join("\n")
  end

  def fragment(line: nil, column: nil, source_map_name: nil, code: '', sexp_type: nil)
    double('Fragment', line: line, column: column, source_map_name: source_map_name, code: code, sexp_type: sexp_type)
  end

  SourcePosition = Struct.new(:line, :column, :file) do
   
    
    def self.absolutize_mappings(relative_mappings)
      reference_segment = [0, 0, 0, 0, 0]
      relative_mappings.map do |relative_mapping|
        # Reference: [generated_column, source_index, original_line, original_column, map_name_index]
        reference_segment[0] = 0 # reset the generated_column at each new line

        relative_mapping.map do |relative_segment|
          segment = []

          segment[0] = relative_segment[0].to_int +  reference_segment[0].to_int
          segment[1] = relative_segment[1].to_int + (reference_segment[1] || 0).to_int if relative_segment[1]
          segment[2] = relative_segment[2].to_int + (reference_segment[2] || 0).to_int if relative_segment[2]
          segment[3] = relative_segment[3].to_int + (reference_segment[3] || 0).to_int if relative_segment[3]
          segment[4] = relative_segment[4].to_int + (reference_segment[4] || 0).to_int if relative_segment[4]

          reference_segment = segment
          segment
        end
      end
    end
