Handlebars.registerHelper 'each_with_index', (array, fn) ->
buffer = ''
for i in array
item = i

buffer += fn(item)
buffer
// {{#each_with_index records}}
// <li class="legend_item{{index}}"><span></span>{{Name}}</li>
// {{/each_with_index}}
Handlebars.registerHelper("each_with_index", function(array, fn) {
var buffer = "";
for (var i = 0, j = array.length; i < j; i++) {
var item = array[i];
// stick an index property onto the item, starting with 1, may make configurable later
item.index = i+1;
// show the inside of the block
buffer += fn(item);
}
// return the finished buffer
return buffer;
});
