RE:
	Petal/Cookbook
	Generating even/odd rows (submitted by Warren Smith)

First- The decode modifier is GREAT.

Unfortunately though, I can't use it as I use Petal to share  
templates between different languages.
For those that need to do the same , there is a way to assign  
attributes based on repeat characteristics in pure TAL

===

<div tal:repeat="row rows">
	<tag tal:omit-tag="string:1" tal:condition="repeat/even"><tag  
tal:define="rowClass string:rowEven" tal:omit-tag="string:1"/></tag>
	<tag tal:omit-tag="string:1" tal:condition="repeat/odd"><tag  
tal:define="rowClass string:rowOdd" tal:omit-tag="string:1"/></tag>
	<div
		tal:attributes="class rowClass"
	>
	This will use either the rowEven or rowOdd class. All of the 'tag'  
elements are omitted on render. This uses a nested define tag in a  
condition tag, because define precedes condition in order of operations.
	</div>
<div>

===

The above is ugly and inefficient. , but if decode: is not an option,  
it saves time spend making&updating duplicate conditional rows (one  
for even, one for odd) , which can be a hassle to maintain when  
designing things.
