I modified my build.sbt according to the instruction and it looks like there is no library distribution for scala 2.13 in the repository.

[error] (core / ssExtractDependencies) sbt.librarymanagement.ResolveException: Error downloading de.b-studios:effekt_2.13:0.4-SNAPSHOT

Is there a way to fix this? I would be happy to get some help 🙏

For some reason the link to Your first effect is dead. 😢

All other links seem to work though.

Is there a way to implement a handler similar to ambList that returns a stream, lazily returning the results?
My naive attempt did not work, but will result in an infinite loop:

def ambStream[R](prog: Amb => Control[R]): Control[Stream[R]] =
  new Handler[Stream[R]] with Amb {
    def flip() = use { resume =>
      for {
        x <- resume(true)
        y <- resume(false)
      } yield x ++ y
    }
  } handle { amb => prog(amb).map(Stream(_)) }

def flip(implicit amb: Amb): Control[Boolean] = amb.flip()

def from(n: Int)(implicit amb: Amb): Control[Int] = for {
  x <- flip
  y <- if (x) pure(n) else from(n + 1)
} yield y

Hello,

libraryDependencies += "de.b-studios" %% "effekt" % "0.3-SNAPSHOT" does not work.

The modul wasn't found, so maybe the repo
https://repo1.maven.org/maven2/de/b-studios/scala-effekt_2.12/0.3-SNAPSHOT/scala-effekt_2.12-0.3-SNAPSHOT.pom
is down?
