Handlebar each helper

Hi!

I was wondering if there's a way to know the current index of the iteration when using the #each helper. Something like accessing the {{currentIndex}} value shown below.

Code:

{{#someArray}}
     {{currentIndex}}
{{/someArray}}

As a last resort, I'm thinking I might just have to add an index attribute to each of the objects in the array that the #each will be iterating over.

Thanks.

It does not supply the index to an `{{#each}}` block:

Hi there,

Oh well, that's not a big deal. There's a perfectly suitable (and perhaps cleaner) workaround, which I stated above.

Thanks for responding, Eric.

Yeah, I agree.

The limitations imposed by Handlers are good at keeping one from putting too much logic/coding in their templates.
