[jira] [Resolved] (SLING-2648) Add Resource Access Tags

["Bertrand Delacretaz (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SLING-2648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bertrand Delacretaz resolved SLING-2648.
----------------------------------------

    Resolution: Fixed

Committed your latest patch in revision 1428328, many thanks for your contribution!

I have also removed the @author tags in revision 1428330 - we don't use them in Sling, mainly because we don't want people to contact authors directly, the code is the responsibility of the whole project. Credit is given via our commits logs and svn blame info - feel free to discuss on the Sling dev list if you have any questions about this.

> 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>
