Support for inline list rendering

[lyonssp]

I want to serialize my yaml list inline, rather than producing to the more common multi-line rendering.

Want:

foo:
  list: [this, list, of, stuff]

Default:

foo:
  list:
  - this
  - list
  - of
  - stuff

It doesn't seem like this kind of serialization is documented, but I was wondering if it is supported at all.

More broadly, is there a way to hook into the printing process to dictate how YamlValue objects are rendered?

Yes, you can explicitly use your own YamlPrinter instance to control the format. For your specific case, there's already a built-in option to output inline lists:

    val yaml = YamlArray(
      YamlString("a"),
      YamlString("b"),
      YamlString("c")
    )

    val printer = new SnakeYamlPrinter(flowStyle = Flow)

    yaml.print(printer) should === (
      """[a, b, c]
        |""".stripMargin)
