conditional operator in Velocity

Question

Is there a way to do ternary operators in Velocity? This is what I'd like to do:

#set ($name = ($args.get(0) == "") ? "default" : $args.get(0))

Instead of chunky if-else

#if ($args.get(0) == "")
    #set ($name = "default")
#else
    #set ($name = $args.get(0))
#end

Any ideas?

Answer 1

I ended up doing as you said, Mark:

#macro(condOp $check, $default)
    #if ($check == "")
        $default
    #else
        $check
    #end
#end

And then I can call it like so:

#set ($name = "#condOp($args.get(0), 'default')")

For the record, with Velocity 2.1+, you can provide alternate reference values:

${args[0]|'default'}
