key:value set

[Tightrope]

I am trying to write a simple key:value set in Pkl and output to yaml.

Expected .yaml output:

- item1key1: "string1"
  item1key2: "string2"

How do I define the above in Pkl where the output does not contain a key for the Set itself. The above output is exactly what I want.

As you've noticed, Pkl cannot represent Listing values (or any other collection) at the module top-level. In these cases, the recommended practice is to override the module's output.value:

things: Listing<Thing> = new {
  new {
    item1key1 = "string1"
    item1key2 = "string2"
  }
}

output {
  value = things
  renderer = new YamlRenderer {}
}

A couple things to note here:

• output.value's default value here is module.
• This example forces output.renderer to YamlRenderer as the default PcfRenderer only supports keyed objects at the top level (just like Pkl modules).
