Chimney implementation ideas

Separate automatic derivation from semiautomatic

Directly solves:

General idea of the solution

Currently Chimney attempts to derive as much as possible with a single expression. It inline results on Scala 2 it uses an approach where when implicit is summoned it is expected that only user-provided implicit would be used. This is done because:

type ~>[F[_], G[_]] = [A] => F[A] => G[A]
final case class <~>[F[_], G[_]](to: F ~> G, from: G ~> F):
val mapAsTo: [A, B] => (G[A] => G[B]) => (F[A] => F[B]) =
[A, B] => (f: (G[A] => G[B])) => to[A].andThen(f).andThen(from[B])
val mapAsFrom: [A, B] => (F[A] => F[B]) => (G[A] => G[B]) =
[A, B] => (f: (F[A] => F[B])) => from[A].andThen(f).andThen(to[B])
extension [F[_], A](fa: F[A])
transparent inline def mapAs[G[_]]: [B] => (G[A] => G[B]) => F[B] =

My public speeches

Actually, more like hall of shame because I cannot watch/listen to myself without cringe, but in this time and age everyone has to be a salesman. Well, not really, but it kind of help with self-development and getting confidence, so whatever. Remember kids! You don't have to be competent to be a public speaker! (Or write a book. Or blog. Or OSS. Or get a job.)
