Class t.w.w.w.ExpandMacro(Widget):

A Macro expansion widget modeled after the METAL expander in ZPT/TAL/METAL. Usage:

In the Page that is being rendered, place the ExpandMacro widget on the node you want replaced with the Macro, and provide nodes tagged with fill-slot= attributes which will fill slots in the Macro:

   def wvfactory_myMacro(self, request, node, model):
       return ExpandMacro(
           model,
           macroFile="MyMacro.html",
           macroName="main")
   
   <div view="myMacro">
       <span fill-slot="greeting">Hello</span>
       <span fill-slot="greetee">World</span>
   </div>

Then, in your Macro template file ("MyMacro.html" in the above example) designate a node as the macro node, and nodes inside that as the slot nodes:

   <div macro="main">
       <h3><span slot="greeting" />, <span slot="greetee" />!</h3>
   </div>
