How to get a zero-based count in a Velocity foreach loop

Question

I am trying to get a zero-based counter in a Velocity #foreach directive.

if i use:

#foreach ($item in $list)
   item.getName() : $veloc         


        

Answer 1

According to the doc, you can specify:

directive.foreach.counter.initial.value = 0

In velocity.properties file.

Answer 2

#set($i = 0)

  #foreach($str in $names)
    #set($i = $i+1)
    $i : $str
 #end

Answer 3

If you are using Velocity 1.7 there are $foreach.index (0-based) and $foreach.count (1-based) special vars available inside loops.

$velocityCount is something that was deprecated long time ago afaik.

Answer 4

Well, you can't have both, obviously--you either need to just do the math when you're displaying, or create a custom directive (and here's the article the SO post links to). For instance, you could have #forEachZeroBased and #forEachOneBased.

Custom directives are very useful sometimes, although IMO this isn't one of them--just do the math, it's the obvious solution, and it's just not that big of a deal.
