0.10.0-RC2

More breaking changes

• #283 The exec_ function has been renamed to filterExec (transactions and pipelining).
• #284 The API has been greatly simplified while also improving type inference

A new quick start section has been added to the documentation:

import cats.effect._
import cats.implicits._
import dev.profunktor.redis4cats.Redis
import dev.profunktor.redis4cats.effect.Log.NoOp._

object QuickStart extends IOApp {

  override def run(args: List[String]): IO[ExitCode] =
    Redis[IO].utf8("redis://localhost").use { cmd =>
      for {
        _ <- cmd.set("foo", "123")
        x <- cmd.get("foo")
        _ <- cmd.setNx("foo", "should not happen")
        y <- cmd.get("foo")
        _ <- IO(println(x === y)) // true
      } yield ExitCode.Success
    }

}

New constructors

• Redis[IO].utf8("redis://localhost")
• Redis[IO].simple("redis://localhost", longCodec)
• Redis[IO].clusterUtf8("redis://localhost:30001")
• Redis[IO].cluster("redis://localhost:30001", someCodec)

This greatly simplifies the creation of RedisCommands[F, K, V] while improving type inference (note that K and V are inferred from the codec passed as an argument) thanks to the partially applied trick.

(*) It has been split into two different files.

Typed-transactions & Pipelining

Typed-transactions and pipelining now make use of a custom HLists. Types are now fully inferred. For example:

//type Cmd = IO[Unit] :: IO[Unit] :: IO[Option[String]] :: IO[Unit] :: IO[Unit] :: IO[Option[String]] :: HNil
val operations =
  cmd.set(key1, "sad") :: cmd.set(key2, "windows") :: cmd.get(key1) ::
      cmd.set(key1, "nix") :: cmd.set(key2, "linux") :: cmd.get(key1) :: HNil

//type Res = Option[String] :: Option[String] :: HNil
val prog =
  RedisTransaction(cmd)
    .exec_(operations)
    .flatMap {
      case res1 ~: res2 ~: HNil =>
        putStrLn(s"res1: $res1, res2: $res2")
    }
    .onError {
      case TransactionAborted =>
        putStrLn("[Error] - Transaction Aborted")
      case TransactionDiscarded =>
        putStrLn("[Error] - Transaction Discarded")
      case _: TimeoutException =>
        putStrLn("[Error] - Timeout")
    }
