ember-eval-helper

This addon introduce e (eval) helper, to allow this syntax usage in templates:

• this addont don't use eval.

<button {{action (e "alert") "Hello" target=(e "window") }}>
  onclick = window.alert("hello")
</button>

{{#let (e "{ projectName: 'Ember' }") as |project|}}
  <h2 id="title">{{project.projectName}}</h2>
{{/let}}


{{#each (e "[1,2,3,4]") as |item|}}
    Number: {{item}}
{{/each}}

this scope access also supported, passing it as second argument

export {
    name: "foo"
}

{{e 'this.name' this}}

Manual this context creation:

<MyComponent
  @params={{
    e "this.onClick(this.foo, this.bar)" 
      (hash
        onClick=(e "this.onClick.bind(this)" this)
        foo=@foo
        bar=(array 1 2 3)
      )
  }}
/>

Sugar: Angle components tagged values will be autocompiled.

// input
<MyComponent @name="`this.realName()`" />

// output
<MyComponent @name={{e 'this.realName()' this}}>
