Output multi-line text?

[Steven Canfield]

Hello,

I'm trying to replicate a setup I have with a k8s configmap that looks like:

apiVersion: v1

kind: ConfigMap

data:

  top_level_key: |

    a: 1

    b: 2

The point of this is that "top_level_key" contains a YAML doc itself.

When I generate this structure with jsonnet, I end up with 

data:

  top_level_key: "a: 1\nb: 2"

which is of course the same thing, but makes reading the thing as a human much harder. 

I can work around this with a shell script to generate the contents of top_level_key with one invocation of jsonnet and then import it using includestr, but it would be nice not to need the driver script.

Is there a way to "output multiline text" without 2 invocations of jsonnet?

One workaround I've found is just to accept jsonnet's output and pipe the whole thing through yq -P which isn't awful.

It sounds like you're asking for std.manifestYamlDoc to support outputting multiline strings for strings that have newlines in them?

Yep exactly.
