Description

I know it's a pretty big thing, but we should at least file it now to discuss it. This ticket is about the idea to support Hyperloop-based Views with Alloy. Example:

var view = new UIView();
view.setBackgroundColor(UIColor.redColor());
view.setFrame(CGRectMake(20,20,300,300));

would become:

<Alloy>
  <UIView class="myView" />
</Alloy>

".myView": {
  backgroundColor: UIColor.redColor,
  frame: CGRectMake(20,20,300,300)
}

I'm not sure if I'd be a fan of this. How would Alloy know if a tag is for Titanium or HL? I'd like to remove some of the magic from Alloy for 2.0, not add more. I think best practice for HL should be to build (cross-platform) factory libraries that in Alloy you'd then simply use via the existing module attribute.

You can already create custom tags in Alloy that link to Hyperloop code. I am MUCH more in favor of that approach vs what is mentioned below. [~fokkezb]'s comments are accurate. See my gist on how to do this. https://gist.github.com/grantges/1c5df7f7b0eada2c4610

Closing this issue, since it's already possible with the suggested Alloy tags. We need some documentation around it, but that's fine. Thanks [~bgrantges@appcelerator.com]!
