How to append a character while using the conditional statement in sightly?

Question

I need to set the href value depending on the nullity of sling:vanityPath. The hit.properties.sling:vanityPath returns the string value for sling:vanityPath property. I need to append a / before the hit.properties.sling:vanityPath value. Is it possible to do that in the following code or do I have to test it twice, but that comes with code repetition?

<a href="${hit.properties.sling:vanityPath == null? hit.path : hit.properties.sling:vanityPath @ extension='html'}"/>

Answer 1

Concatenation or binary operators are not supported in HTL. You can either use prependPath or double test for the slash.
