Add a way to modify the template inside an Attached Behaviour before element compilation about framework

[Serhioromano]

Not clear what would be the template? Is it URL string, HTML string or ID of the element? Or it is template content? Can you add practical example in real world scenario?

This issue started when i asked this this question :

is it possible to add a behaviour to an element that will include other behaviours ?

for example if i have a bunch of behaviours

<div focusable hoverable draggable droppable></div>

i want to be able to write one attribute that will activate all these behaviours , something like

<div ui></div>

adding the ui behaviour would in turn enable all the behaviours specified above

there is currently already a way to do something like this, where you should inject the child behaviours into one parent behaviour and initialize the child behaviours like this

constructor(Element, BoldTextBehavior, YellowBehavior){
    this.element = Element;
    this.bold = BoldTextBehavior;
    this.yellow = YellowBehavior;

    this.bold.element = this.element;
    this.yellow.element = this.element;
}

But allowing us to simply change the template before it is compiled would allow us to add attributes to the dom element and let aurelia initialize all the child behaviours based on those attributes.

Has there been any progress around this ?

Hasn't been done yet.

The new view resource pipeline steps allow you to create resources that can be imported into a view which modify the template before compliation.
