> Add Resource Access Tags

> Key: SLING-2648
> URL: https://issues.apache.org/jira/browse/SLING-2648

> Reporter: Dan Klco
> Labels: patch, scripting, taglib

> It would be really nice to be able to access resources through tags rather
> than having to use Scriptlet for even basic Resource iteration. I've created
> a patch for adding tags to:
> - Get a Resource
> - List Child Resources
> - Adapt adaptables to other classes
> - Get properties from ValueMaps (with default values)
> With these new tags, you will be able to do things like create an entire
> navigation without scriptlet:
> <ul>
> <sling:getResource var="currentResource" path="/libs" />
> <sling:listChildren var="children" resource="${currentResource}" />
> <c:forEach var="child" items="${children}">
> <c:if test="${child.name != 'jcr:content'}">
> <sling:getResource var="pageContent"
> path="${child.path}/jcr:content" />
> <sling:adapt adaptable="${pageContent}"
> adaptTo="org.apache.sling.api.resource.ValueMap" var="childProperties" />
> <sling:getProperty key="jcr:title" defaultValue="${child.name}"
> var="title" properties="${childProperties}" />
> <li><a href="${child.path}.html">Title: ${title}</a></li>
> </c:if>
> </c:forEach>
> </ul>
