ScalaLoci

ScalaLoci is a distributed programming language embedded into Scala. The language provides a coherent model based on placement types that enables reasoning about distributed data flows, supporting multiple software architectures via dedicated language features and abstracting over low-level communication details and data conversions. ScalaLoci simplifies developing distributed systems, reduces error-prone communication code and favors early detection of bugs.

Getting ScalaLoci

• Enable support for macro annotations in your build.sbt:

  • for Scala 2.13

    scalacOptions += "-Ymacro-annotations"
    

  • for Scala 2.11 or 2.12 (Macro Paradise Plugin)

    addCompilerPlugin("org.scalamacros" % "paradise" % "2.1.1" cross CrossVersion.patch)
    

• Add the ScalaLoci dependencies that you need for your system to your build.sbt:

  • ScalaLoci language (always required)

    libraryDependencies ++= Seq(
      "io.github.scala-loci" %% "scala-loci-language" % "0.5.0" % "compile-internal",
      "io.github.scala-loci" %% "scala-loci-language-runtime" % "0.5.0")
    

  • Transmitter for the types of values to be accessed remotely (built-in Scala types and standard collections are directly supported without additional dependencies)

    • REScala reactive events and signals

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-language-transmitter-rescala" % "0.5.0"
      

  • Network communicators to connect the different components of the distributed system

    • TCP [JVM only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-tcp" % "0.5.0"
      

    • WebSocket (using web browser APIs) [JS only, client only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-ws-webnative" % "0.5.0"
      

    • WebSocket (using Akka HTTP) [JVM only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-ws-akka" % "0.5.0"
      

    • WebSocket (Play integration using Akka HTTP) [JVM only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-ws-akka-play" % "0.5.0"
      

    • WebSocket (using Javalin) [JVM only, server only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-ws-javalin" % "0.5.0"
      

    • WebSocket (using Jetty) [JVM only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-ws-jetty" % "0.5.0"
      

    • WebRTC (using web browser APIs) [JS only]

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-communicator-webrtc" % "0.5.0"
      

  • Serializer for network communication

    • µPickle serialization

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-serializer-upickle" % "0.5.0"
      

    • Circe serialization

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-serializer-circe" % "0.5.0"
      

    • Jsoniter Scala serialization

      libraryDependencies +=
        "io.github.scala-loci" %% "scala-loci-serializer-jsoniter-scala" % "0.5.0"
      

Using ScalaLoci network communication as a library

ScalaLoci’s underlying network communication library abstracting over different network protocols can be used directly without ScalaLoci’s language abstractions. The library provides pluggable communicators for different network protocols and transmitters implementing the remote transmission semantics for values of different types.

Add the ScalaLoci dependencies that you need for your system to your build.sbt:

• ScalaLoci communication library (always required)

  libraryDependencies +=
    "io.github.scala-loci" %% "scala-loci-communication" % "0.5.0"
  

• Transmitter for the types of values to be accessed remotely (built-in Scala types and standard collections are directly supported without additional dependencies)

  • REScala reactive events and signals

    libraryDependencies +=
      "io.github.scala-loci" %% "scala-loci-transmitter-rescala" % "0.5.0"
    

• Network communicators to connect the different components of the distributed system (same as above)

• Serializer for network communication (same as above)
