Use ternary operator in freemarker?

Question

I just want to do something like this:

Answer 1

As of FreeMarker 2.3.23 you can write a?then('a.htm', 'b.htm'). The advantage of condition?then(whenTrue, whenFalse) over condition?string(whenTrue, whenFalse) is that it works for non-string whenTrue and whenFalse, and that it only evaluates one of whenTrue and whenFalse expressions (whichever branch is chosen).
