      options[:renderer] ||= MaterializeLinkRenderer
      super.try :html_safe
    end

    class MaterializeLinkRenderer < LinkRenderer
      protected

      def html_container(html)
        tag :ul, html, container_attributes
      end

      def page_number(page)
        tag :li,
            link(page, page, rel: rel_value(page)),
            class: (page == current_page ? 'active' : 'waves-effect')
      end

      def previous_or_next_page(page, text, classname)
        if classname == "previous_page"
          tag :li, link('<i class="material-icons">chevron_left</i>', page || '#'), :class => ["waves-effect", classname, ('disabled' unless page)].join(' ')
        else
          tag :li, link('<i class="material-icons">chevron_right</i>', page || '#'), :class => ["waves-effect", classname, ('disabled' unless page)].join(' ')
        end
      end

      def gap
        text = @template.will_paginate_translate(:page_gap) { '&hellip;' }
        %(<li><span class="gap">#{text}</span></li>)
      end
