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: config.rb
    path of file: ./repos/middleman/middleman-core/fixtures/frontmatter-settings-neighbor-app
    
    the code of the file until where you have to start completion: # Proxy ignored.html, which should ignore itself through a frontmatter
proxy 'proxied.html', 'ignored.html'
proxy 'proxied_with_frontmatter.html', 'ignored.html'
page 'override_layout.html', layout: :alternate
page 'page_mentioned.html'

ignore '*.frontmatter'


    
  def manipulate_resource_list(resources)
    resources.each do |resource|
      next unless resource.file_descriptor
      next if resource.file_descriptor[:relative_path].extname == '.frontmatter'

      [
        "#{resource.url.sub(/^\//, '')}.frontmatter",
        "#{resource.file_descriptor[:relative_path]}.frontmatter"
      ].each do |n|
        file = app.files.find(:source, n)
        apply_neighbor_data(resource, file) if file
      end
    end
  end
