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: meta-tag.rb
    path of file: ./repos/jekyll-feed/lib/jekyll-feed
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module JekyllFeed
  class MetaTag < Liquid::Tag
    # Use Jekyll's native relat
    
    def render(context)
      # Jekyll::Filters::URLFilters requires `@context` to be set in the environment.
      @context = context

      config = context.registers[:site].config
      path   = config.dig("feed", "path") || "feed.xml"
      title  = config["title"] || config["name"]

      attributes = {
        :type => "application/atom+xml",
        :rel  => "alternate",
        :href => absolute_url(path),
      }
      attributes[:title] = title if title

      attrs = attributes.map { |k, v| "#{k}=#{v.to_s.encode(:xml => :attr)}" }.join(" ")
      "<link #{attrs} />"
    end
