The Scala library "Scala Effekt" is discontinued. In 2020, its development has been superseded by our own standalone programming language Effekt, independent of Scala.
Due to its origins, but confusingly, both carry Effekt in their name. To disambiguate, we recommend to use Scala Effekt to refer to the library and Effekt to the standalone programming language.
The evolution of the Effekt language and its predecessors is explained here.
The Effekt library allows you to structure your effectful programs in a functional way. It thus represents an alternative to traditional monad transformer based program structuring techniques.
To use Effekt (tested with Scala 2.12 and Scala 2.13), include the
following line to your build.sbt file:
resolvers += Opts.resolver.sonatypeSnapshots
libraryDependencies += "de.b-studios" %% "effekt" % "0.4-SNAPSHOT"To learn how to use the library, see Your First Effect.
