Support for NULL in Smarty?!

It was already discussed some time ago ... but I cannot find the thread anymore and I cannot remember if a decission was made. I cannot use NULL as a function parameter in Smarty. But it would be very usefull for me to explicitly set some vars to NULL. For example if a function has set a parameter to a default value other that "" or NULL. One other thing I discovered is the behaviour of TRUE and FALSE within a template. Both get compiled as 1 or 0 not as true / false. It's nearly the same but not exacly. So I have created patch which "fixed" the TRUE/FALSE and adds support for NULL: Index: Smarty_Compiler.class.php =================================================================== RCS file: /repository/smarty/Smarty_Compiler.class.php,v retrieving revision 1.177 diff -r1.177 Smarty_Compiler.class.php 56c56 < var $_permitted_tokens = array('true','false','yes','no','on','off'); --- > var $_permitted_tokens = array('true','false','yes','no','on','off','null'); 664a665,666 > if (is_null($arg_value)) > $arg_value = 'null'; 1345c1347 < $token = true; --- > $token = 'true'; 1347c1349,1351 < $token = false; --- > $token = 'false'; > } else if ($token == 'null') { > $token = 'null'; Good or bad?
