mod function?

[phillip rhodes <rh...@telerama.com>]

Hi.
When I looping through with a #foreach
I would like to print out some content every 3rd iteration.

While I can do this using variables, etc, I was wondering if there is a velocity elegant way to do this.
Thanks.

It's easy and already available:
#foreach($item in $items)
#set($var = $velocityCount % 3)
$var
#end

BTW. It is always good to read the users guide on velocity site or docs
provided with the distribution. It will certainly save You some time.

Take care,

Hi Phillip,

There is a mod operator built in:

#foreach( $letter in ["a","b","c","d","e","f","g","h","i","j"] )
#if( $velocityCount % 3 == 0 )$letter #end
#end

Note the $velocityCount variable *may* have been renamed in your 
configuration.
