Note:

In case you're wondering, the code behind the view engines derives from the "github.com/kataras/iris/view" package,
access to the engines' variables can be granded by "github.com/kataras/iris" package too.

    iris.HTML(...) is a shortcut of view.HTML(...)
    iris.Django(...)     >> >>      view.Django(...)
    iris.Pug(...)        >> >>      view.Pug(...)

    iris.Amber(...)      >> >>      view.Amber(...)
