New notation for replacing null values with a specified string
--------------------------------------------------------------
Key: VELOCITY-756
URL: https://issues.apache.org/jira/browse/VELOCITY-756
Project: Velocity
Issue Type: New Feature
Components: Engine
Reporter: Ludwig Magnusson
Priority: Minor
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 "-".
