I have a MyScript.scala file:

//> using scala "3"

object MyUtils {
  def sayHello() = println("Hello")
}

@main
def main(): Unit =
  MyUtils.sayHello();

I successfully run it like this:

> scala MyScript.scala

Compiling project (Scala 3.6.4, JVM (17))
Compiled project (Scala 3.6.4, JVM (17))
Hello

Question: What do I need to do to move my MyUtils object into another source file (e.g., MyUtils.scala or MyUtils.sc) and still call the sayHello method from within MyScript.scala?

Reset to default 3

With the Scala CLI, you can use the using file directive.

For instance, in the main file:

//> using scala "3"
//> using file Utils.scala

@main
def main(): Unit = {
  MyUtils.sayHello()
}

And the imported file Utils.scala:

object MyUtils {  
  def sayHello() = println("Hello")
}
