View source for Context item (extension point)

{{Extension point|template|ru.biosoft.templates|since=0.8.7|registry=ru.biosoft.templates.TemplateRegistry}}
=== Description ===
This extension allows you to add objects which will be accessible during [[Template (extension point)|velocity template]] execution.

=== Configuration Markup ===
 <!ELEMENT helper>
  <!ATTLIST helper
     name         CDATA    #REQUIRED
     class        CDATA    #REQUIRED
 >

;name
:name of the variable accessible during template execution. For example, if <code>"test"</code> is specified, then you can refer to it inside the template as <code>$test</code>.
;class
:fully-qualified name of the class to instantiate. This class must have default constructor. The only one global instance of this class is created for all templates execution, thus it's highly recommended that this class has no internal state.

=== Example ===
 <extension id="utils" point="ru.biosoft.templates.contextItem">
   <helper name="utils" class="ru.biosoft.templates.Formatter" />
 </extension>

Now an instance of {{Class|ru.biosoft.templates.Formatter}} class will be accessible from any velocity template via <code>$utils</code> variable.
