How to use scala-yaml for scala2？

[colin4124]

Document's example is all about scala 3, how about scala2 ?

Hey @colin4124! There is no codec/encoder derivation for Scala 2 so you can only convert Strings to YAML AST. However, there is an integration with circe created by @armanbilge - https://github.com/armanbilge/circe-scala-yaml. Below I pasted scala-cli snippet with some usage of them both.

//> using scala "2.13.10"
//> using lib "org.virtuslab::scala-yaml::0.0.6"
//> using lib "com.armanbilge::circe-scala-yaml::0.0.4"

import org.virtuslab.yaml._
import io.circe.scalayaml._

object Yaml extends App {
  val myYaml = """foo: bar"""

  println(parser.parse(myYaml))
  println()
  println(myYaml.asNode)
}

Thanks so much, I use circe-scala-yaml directly, it works.
