Cycling with Jinga

I was tweaking the layout.html file for Python's Sphinx and found the following random tit-bit of use when using Jinga:


{%- for rellink in rellinks[1:]|reverse %}
  <div class="{{ loop.cycle('buttonPrevious', 'buttonNext') }}">
   <a href="{{ pathto(rellink[0]) }}">
    {{loop.cycle('Previous', 'Next')}}
  </a>
{%- endfor %}




With loop.cycle you can cycle through strings or divs
as the loop iterates..

In the above example, a div is created first for buttonPrevious and then
the next iteration for buttonNext. The same applies to the strings that determine what gets
printed on the button.
