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

module RubyJard
  class Screens
    ##
    # Display source code of current stopping line and surrounding lines
    class SourceScreen < RubyJard::Screen
      include ::RubyJard::Span:
    
      def initialize(**args)
        super(**args)
        @frame_file = @session.current_frame&.frame_file
        @frame_line = @session.current_frame&.frame_line

        if !@frame_file.nil? && !@frame_line.nil?
          @path_decorator = RubyJard::Decorators::PathDecorator.new
          @loc_decorator = RubyJard::Decorators::LocDecorator.new
          @source_decorator = RubyJard::Decorators::SourceDecorator.new(@frame_file, @frame_line, @layout.height)
        end
