기본 사용법

https://scala-cli.virtuslab.org/ 사용법 소개

(scala 2.13 을 사용 중인데, scala 3 survey 에 scala-cli 를 활용해 보았다.)

Run scripts

hello.sc

def helloMessage(names: Seq[String]) = names match
  case Nil =>
    "Hello!"
  case names =>
    names.mkString("Hello: ", ", ", "!")

println(helloMessage(args.toSeq))
println(os.pwd)

 

실행

scala-cli \
  --jvm 21 \
  --dep com.lihaoyi::os-lib:0.9.0 \
  hello.sc -- James Candy

 

 

 

Run scala code

Test.scala (scala-3.3.1)

//> using dep com.lihaoyi::os-lib:0.9.3
//> using dep com.softwaremill.ox::core:0.0.18

import ox.par

object Test {
  def computation1: Int =
    Thread.sleep(2000)
    1

  def computation2: String =
    Thread.sleep(1000)
    "2"

  def main(args: Array[String]): Unit =
    val result: (Int, String) = par(computation1)(computation2)

    println(result)
}

 

실행

scala-cli run --jvm 21 Test.scala
