Re: A WM brain bender

Looking at the test case in CVS ( 
http://cvs.sourceforge.net/viewcvs.py/webmacro/webmacro/test/unit/org/webmacro/template/TestEvalTemplet.java?rev=1.1&view=markup)
I see that I created a convenience class for doing this during testing:

//** Convenience class to evaluate a string template as a Macro *//
*public* *class* StringMacro *implements* org.webmacro.Macro
{
  *private* String s = *""*;
  *public* StringMacro(String text)
  {
      s = text;
   }
   *public* Object evaluate(Context context) *throws* 
org.webmacro.PropertyException
   {
      org.webmacro.engine.StringTemplate t = *new* 
org.webmacro.engine.StringTemplate(context.getBroker(), s); *return* 
t.evaluateAsString(context);
   }
   *public* *void* write(org.webmacro.FastWriter fw, Context context) { }
}

This let's you use arbitrary strings as macros, e.g.,

StringMacro m = *new* StringMacro(*"$A $B $C"*);

I think the $Template tool can be used similarly.
