Ludwig Magnusson commented on VELOCITY-756:
-------------------------------------------
I did not know that this feature existed and I agree that it is a better and
more flexible solution.
Thanks for the comment.
> 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 "-".
