Special logic for last iteration of collection
Hello everyone,
I am just starting with velocity. I am trying to generate a comma delimited
list (method arguments) and would like it to appear like this:
(item1, item2, item3)
I can't figure out how to not add a comma if we are on the last element of
our list. Could someone help me out?
Regards,
Joshua

Hi Joshua,
you may use the $velocityCount == $list.size() or $list.size() + 1 to
figure out when you are on the last element, depending on the start
value of $velocityCount

Try
(#foreach($element in $list)$element#if($velocityCount==list.size()))#else,#end
Starts with a (, then the element followed by a comma if we're not on
the last element, followed by a ) if this is the last element.

Avoid the stated $velocityCount reference, just do:
#set( $sep = "" )
(#foreach( $param in $parmlist )$sep$param#set( $sep = ", " )#end)
Hope this helps,
