dhall-to-yaml-ng quotes the keys that contain a dash while dhall-to-yaml does not

I don't quite understand why this simple file:
Given this command:

→ dhall-to-yaml-ng --file openshift/examples/test.dhall --output openshift/examples/test.yaml

Using this input file:

let k8s =
      https://raw.githubusercontent.com/dhall-lang/dhall-kubernetes/master/1.17/package.dhall sha256:7150ac4309a091740321a3a3582e7695ee4b81732ce8f1ed1691c1c52791daa1

in  k8s.Namespace::{
    , metadata = k8s.ObjectMeta::{
      , name = Some "test"
      , annotations = Some
          ( toMap
              { `openshift.io/display-name` = "A very long name"
              , `openshift.io/requester` = "test"
              }
          )
      }
    }

I will get this output yaml file:

apiVersion: v1
kind: Namespace
metadata:
  annotations:
    "openshift.io/display-name": A very long name
    openshift.io/requester: test
  name: test

I can't really make sense of the dichotomy of the two annotations.

If I use dhall-to-yaml I have this output file

apiVersion: v1
kind: Namespace
metadata:
  annotations:
    openshift.io/display-name: A very long name
    openshift.io/requester: test
  name: test

Sorry about that. I have just realized there is a much simpler user case:

→ echo '{ `display-name` = "hello world" }' | dhall-to-yaml
display-name: hello world

→ echo '{ `display-name` = "hello world" }' | dhall-to-yaml-ng
"display-name": hello world

Is there any reason to quote the key when it contains a - ?

I think the underlying issue is haskell-hvr/HsYAML#37.

@sjakobi thanks ! The activity on that repo doesn't look promising for the future, does it ?

[sjakobi]

It's hard to say. If someone would provide a fix it could be released fairly soon, I guess. The maintainer is quite busy though.
