Support for multidocument YAML output

[mrzor]

Is your feature request related to a problem? Please describe.
When using Cue to generate several Kubernetes manifests, I presently have to script around Cue and invoke it many times to output several documents. Invocations looks like cue export ... -e "_jobs[$i]" with $i being a shell variable.

Describe the solution you'd like
I would like the YAML encoder to support outputting multiple documents, but I cannot imagine a clean way for this to happen.

Describe alternatives you've considered
I'm thinking of reducing the pain caused by the slowness by outputing only one big YAML document (containing _jobs ) and then using yq or similar to split it.

You can use https://pkg.go.dev/cuelang.org/[email protected]/pkg/encoding/yaml#MarshalStream. See https://github.com/cue-lang/cue/blob/f681271a38ec/doc/tutorial/kubernetes/README.md#dumping-a-yaml-stream for an example.

Thanks a lot mxey I appear to have overlooked this part of the tutorial. This will address my use case just fine. Closing this ticket.
