'How to compile and execute scala code at run-time in Scala3?
I would like to compile and execute Scala code given as a String at run-time using Scala3. Like for example in Scala 2 I would have used Reflection
import scala.reflect.runtime.universe as ru
import scala.tools.reflect.ToolBox
val scalaCode = q"""println("Hello world!")"""
val evalMirror = ru.runtimeMirror(this.getClass.getClassLoader)
val toolBox = evalMirror.mkToolBox()
toolBox.eval(scalaCode) //Hello world!
If I try to run this code in Scala3 I get
Scala 2 macro cannot be used in Dotty. See https://dotty.epfl.ch/docs/reference/dropped-features/macros.html
To turn this error into a warning, pass -Xignore-scala2-macros to the compiler
How can I translate this code in Scala3 ?
