I would like to show my new "actionloop" based Scala runtime! Yes I know, it is already possible to use Scala with the Java runtime. But you have to compile, create a jar, include libraries This one is based on the scripting shell "Ammonite" http://ammonite.io and works more like js and python.
Here is a simple demo: https://openwhisk.eu-de.bluemix.net/api/v1/web/sciabarra_cloud/scala/calc And this is the source code: ---- import play.api.libs.json._ import scala.util.Try def main(args: JsObject) : JsObject = { val a = if(args \ "a" isDefined) { Try(args("a").as[String].toInt).getOrElse(0) } else 0 val b = if(args \ "b" isDefined) { Try(args("b").as[String].toInt).getOrElse(0) } else 0 if( args \ "add" isDefined) { html(Some(s"${a} + ${b} = ${a+b}")) } else if ( args \ "mul" isDefined) { html(Some(s"${a} * ${b} = ${a*b}")) } else html() } def html(msg: Option[String]=None) = { val body = s"""<html><body> ${if(msg.isEmpty) "" else "<h1>"+msg.get+"</h1>"} <form> <input name="a" size="4"> <input name="b" size="4"> <button name="add">+</button> <button name="mul">*</button> </form></body></html>""" Json.obj("body" -> body) } ---- Deployed with this command: wsk action update scala/calc calc.sc -m512 --web true --docker msciab/actionloop-scala-v2.12 The runtime is also part of a "collection" of runtimes based on the ActionLoop (the engine of the GoLang runtime) and I want to show how to build a new runtime for any language with just 3 files: a "compiler" script, a launcher and a Dockerfile. I already did the runtimes for Swift and Scala, and I have in mind many others (rust, haskell and kotlin for example). -- Michele Sciabarra [email protected] ----- Original message ----- From: Carlos Santana <[email protected]> To: "[email protected]" <[email protected]> Subject: Tech Interchange call this Wed.
