Prevent PlayFramework's template engine from escaping my Strings

I've created some utilities that help me at generating HTML and I reference them in my views as @div( "class" -> "well" ){ Hello Well. }. Until now those classes were subclassing NodeSeq because they aren't escaped then. But I need to get rid off the NodeSeq in the top of my class hierarchy because Scala's xml is flawed and makes my code hacky and because I could switch to Traits then.

So I tried to find out how to prevent Play from escaping my Tag-objects. But unfortunately the only valid solution that I found is to override the template compiler and have the user specify my compiler in his Build.scala settings.

But I hopefully have overlooked a way more simple approach?

Since version 2.2.0-M1 there appeared a new approach in the docs that explains how to add custom formats to the template engine. This allows me to easily integrate my utilities.

Custom Template Format: Java, Scala

If your html helpers returns 'Html' rather than String you don't need to wrap them using the @Html tag in the view.

eg

import play.api.templates.Html

def a(src: String, value: String) : Html = Html(s"<a href='$src'>$value</a>")

Would be called in the view as below without needing to wrap in @Html

@a("www.example.com", "Example")
