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: error_presenter.rb
    path of file: ./repos/exception_hunter/app/presenters/exception_hunter
    
    the code of the file until where you have to start completion: module ExceptionHunter
  class ErrorPresenter
    delegate_missing_to :error
    delegate :tags, to: :error_group

    BacktraceLine = Struct.n
    
    def format_backtrace_line(line)
      matches = line.match(%r{(?<path>.*)/(?<file_name>[^:]*):(?<line_number>\d*).*`(?<method_call>.*)'})

      if matches.nil?
        line
      else
        BacktraceLine.new(matches[:path],
                          matches[:file_name],
                          matches[:line_number],
                          matches[:method_call])
      end
