Description

If I have a variable $foo and it is null, I have the option of using the silent notation $!foo for not writing it. But often when genrating HTML pages I want to express that the values is missing, e.g. by a "-". That means that I have to write my code like this:

#if($foo)
$foo
#else
-
#end

Wouldn't it be great if there were a new option like $?foo (or whatever chararter would be suitable instead of "?") that would print the variable $foo if it was not null and otherwise print a predefined character like "-".
