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

[jezwn]

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'}"/>

HI, 

It is recommended to do any data manipulation in back end. Null check/equality check can be performed at sightly level. Amending a value based on some condition has to happen in back end and expose it in sightly via getter.

You could use prependPath instead in sightly.

The prependPath could be used to do this.

prependPath - prepends its content to the path that identifies a resource

${'path' @ prependPath='..'}
<!-- outputs: ../path -->

${'path' @ prependPath='/', appendPath='/'}
<!-- outputs: /path/ -->

${'http://example.com/path/page.html' @ prependPath='foo'}
<!-- outputs: http://example.com/foo/path/page.html -->
