  1. final class MutationContext extends AnyRef

    Use this to create utility functions that add bindings mutably to the current module, as opposed to creating new modules and including them.

  21. final def many[T](implicit tag: Tag[Set[T]], pos: CodePositionMaterializer): SetDSL[T]

    Set bindings are useful for implementing event listeners, plugins, hooks, http routes, etc.

    Set bindings are useful for implementing event listeners, plugins, hooks, http routes, etc.

    To define a multibinding use .many and .add methods in ModuleDef DSL:

    import cats.effect._, org.http4s._, org.http4s.dsl.io._, scala.concurrent.ExecutionContext.Implicits.global
import distage._

object HomeRouteModule extends ModuleDef {
  many[HttpRoutes[IO]].add {
    HttpRoutes.of[IO] { case GET -> Root / "home" => Ok(s"Home page!") }
  }
}

    Set bindings defined in different modules will be merged together into a single Set. You can summon a created Set by type Set[T]:

    import cats.implicits._, org.http4s.server.blaze._, org.http4s.implicits._

object BlogRouteModule extends ModuleDef {
  many[HttpRoutes[IO]].add {
    HttpRoutes.of[IO] { case GET -> Root / "blog" / post => Ok("Blog post ``$post''!") }
  }
}

class HttpServer(routes: Set[HttpRoutes[IO]]) {
  val router = routes.foldK

  def serve = BlazeBuilder[IO]
    .bindHttp(8080, "localhost")
    .mountService(router, "/")
    .start
}

val objects = Injector().produce(HomeRouteModule ++ BlogRouteModule)
val server = objects.get[HttpServer]

val testRouter = server.router.orNotFound

testRouter.run(Request[IO](uri = uri("/home"))).flatMap(_.as[String]).unsafeRunSync
// Home page!

testRouter.run(Request[IO](uri = uri("/blog/1"))).flatMap(_.as[String]).unsafeRunSync
// Blog post ``1''!

  22. final def modify[T]: ModifyDSL[T, BindDSL, BindDSLAfterFrom, SetDSL]

    Modify a value bound at T.

    Modify a value bound at T. Modifiers stack and are all applied before T is added to the object graph; only the final instance is observable.

    import distage.{Injector, ModuleDef}

Injector().produceGet[Int](new ModuleDef {
  make[Int].from(1)
  modify[Int](_ + 1)
  modify[Int](_ + 1)
}).use(i => println(s"Got `Int` $i"))
// Got `Int` 3

    You can also modify while summoning additional dependencies:

    modify[Int]("named").by(_.flatAp {
  (adder: Adder, multiplier: Multiplier) =>
    int: Int =>
      multiplier.multiply(adder.add(int, 1), 10)
})
