velocity: do something except in last loop iteration

Question

In velocity, I want to do something different in the last loop.

What is the correct idiom?

@ratchet: same as related question: I am concatenating things with a separator in between and don't want to put the separator after the last item — flybywire, Nov 19 '11 at 20:01

You can use a test if you are in last iteration::

#foreach( $item in $list )
    $item.text #if( $foreach.hasNext ), #end
#end

@soulcheck's answer is what you need, but be aware that the $foreach variable is only available in velocity 1.7, if you're using an earlier version you can use:

#foreach( $item in $list )
    $item.text #if( $velocityHasNext ), #end
#end

However, the $velocityHasNext variable is deprecated in versions 1.7 and removed in 2.0 in favour of $foreach.hasNext.

At the time of writing, there is no version 2.0 of Velocity. – holmis83 Sep 09 '16 at 09:27

The idiom I use is to save the optional text to be added if the loop doesn't finish.

#set($sep = "")    
#foreach($item in $list)
 $sep$item
 #set($sep = ", ")
#end

This worked for me in an older version of Velocity

#if($velocityCount < $list.size()), #end
