Erm, no. At present I have this function in a Smarty subclass:

     //Function takes a template in a string and compiles it through  
Smarty
     public function compile_string_template($templatestring) {
         if($templatestring == '') {
             return '';
         }

         $this->_compile_source('string template', $templatestring,  
$source); //Source is passed by reference to be filled in
         //Dump compiled version in output buffer
         ob_start();
         eval('?>' . $source);
         $evaled = ob_get_contents();
         ob_end_clean();
         return $evaled;
     }

Obviously inefficient, but functional - this code was from a smarty- 
general posting a couple of years ago when I originally asked about  
this!

Now I look at it again, the resource plugin looks promising.

As I recall when I was setting this up originally - the problem is  
the path - there is no path!

I don't use timestamps anywhere now - always ISO datetimes  
(especially now that MySQL 4.1 uses them everywhere), but as you say,  
conversion is not a problem. MySQL's SQL cache is my friend ;^)

I think my question is possibly simpler (and dumber!) - when a  
template is in a string and the compiled results are too, where do  
compiled versions get cached? Still in a local templates_c folder?  
back in the DB? in RAM? Is that decision controllable from a plugin too?
