{{@index}} fails

[tkellen]

var compiler = require('ember-template-compiler');
compiler.precompile('{{#each thing in things}}{{@index}}{{/each}}');

Works fine with handlebars proper. Any idea what might be up?

Great question ... @rjackson any ideas on this one?

@first also fails.

Given a test.hbs file:

<ul>
{{#each items}}
  <li {{#if @first}}class="first"{{/if}}>{{title}}</li>
{{/each}}
</ul>

and a compile.js file:

var fs = require('fs');
var compiler = require('ember-template-compiler');
var template = fs.readFileSync('test.hbs').toString();
var input = compiler.precompile(template).toString();

console.log(input);

When I run node compile.js, I get a cryptic error:

undefined:10
  stack1 = helpers['if'].call(depth0, , {hash:{},hashTypes:{},hashContexts:{},
                                      ^

I spoke with an ember core team member this week at EmberConf and it doesn't sound like this will be getting any love w/out a fix from the community. Does anyone want to dive into the ember project and see how to add support for these?

Ember does not support @index (or any of the other @data type properties).
