zio-magic-comments

ZioMagicComments is a Scalafix rule that adds explanatory graphs as comments to zio-magic methods:

class Demo {
  val program: URIO[Cake, Unit] = ...

  //         Cake.live         ⎫
  //      ┌──────┴─────┐       ⎬ added by ZioMagicComments
  // Clock.live  Blocking.live ⎭
  val magically =
    program.provideMagicLayer(
      Cake.live,
      Clock.live,
      Blocking.live
    )
}
