Groovy

The LumisXP allows you to develop styles in Groovy. To create a style in Groovy, simply create the style and choose the programming language "Groovy".

Groovy is an object-oriented programming language developed for the Java platform as an alternative to the Java programming language. See the Groovy page for more information.

For information about the script format for a style in LumisXP, see the topic Styles in Thymeleaf, Javascript, and Groovy.

Below is an example of a Groovy style similar to that of Quick List from the news service:

<ul class="lum-list">
<%
  def rows = lum_xpath.selectNodes("//data/row");
  for(int i; i< rows.size(); i++)
  {
     Map<String , Object> row = lum_xpath.toMap(rows[i]);
%>
  <li class="lum-list-item"<%=i == 0 ? " lum-first" : "" + i == rows.length-1 ? " lum-last" : ""%>>
    <article class="lum-content" data-lum-entityid="<%=row.contentId%>" data-lum-title="<%=row.title%>" data-lum-url="<%=row.$href%>" data-lum-serviceinstanceid="<%=row.serviceInstanceId%>">
        <header class="lum-content-header">
          <h1 class="lum-content-title">
              <a href="<%=row.$href%>">
                <%=<%=row.title%>
              </a>
          </h1>
          <ul class="lum-content-meta-information">
              <li class="lum-first lum-last">
                 On
                <time datetime="<%=row.publishStartDate.year%>-<%=row.publishStartDate.month%>-<%=row.publishStartDate.day%>T<%=row.publishStartDate.hours%>:<%=row.publishStartDate.minutes%>:<%=row.publishStartDate.seconds%>">
                    <%=row.publishStartDate.value%>
                </time>
              </li>
          </ul>
          <div class="lum-content-introduction">
              <p>
                <%=row.introduction%>
              </p>
          </div>
        </header>
    </article>
  </li>
<%
  }//end of for
%>
</ul>
