In Scala, how do I extend an object with multiple classes? -


how inject app object being extended another?

object foo extends someclass bar {     /* imports */     /* <-- want code here run if within `main` scope --> */    }

basically want take advantage of app main class (example); without receive error:

java.lang.runtimeexception: no main class detected.

(so don't need worry defining own def main (args : array[string]))

why not object foo extends someclass bar app? app trait, mixed class effortlessly.
