[pmwiki-users] Markup Extension writing

[Hans Bracker]

Yes, sum does work. The MarkupExprPlus recipe definitions of add, sub, 
mul and div don't work with 'strcount'. I can fix it and get the value, 
not the token,  by adding a line of code to top of the function, like 
this, calling MarkupRestore():

function MEP_nums($params) {
   $params = trim(MarkupRestore($params));
   $params = preg_split('/\\s+/', $params);
   $args = array();
   foreach ($params as $p) {
     list($d) = sscanf($p, "%g");
     if (is_numeric($d)) $args[] = $d;
   }
   return $args;
}

Is there another way than rewriting recipes?
