help retrieving multiple yaml values

[lordigon]

Hi all,
this is a test yaml I'm using

foo:
  imageTag: 1.0.0-20240219020324
bar:
  comp:
    imageTag: 1.0.23
  artifact:
    imageTag: 1.0.23
  test:
    imageTag: 1.0.16

and i would like to know how can I retrieve the list of all imageTag values. Something like

foo.imageTag 1.0.0-20240219020324
bar.comp.imageTag 1.0.23
bar.artifact.imageTag 1.0.23
bar.test.imageTag 1.0.16

You can deeply prune the document like this:

yq '(.. | select(.imageTag) | .imageTag) as $i ireduce({}; setpath($i | path; $i))'  -o=props

and get a property file format like:

foo.imageTag = 1.0.0-20240219020324
bar.comp.imageTag = 1.0.23
bar.artifact.imageTag = 1.0.23
bar.test.imageTag = 1.0.16

The next release will have a --properties-separator flag that you can specify as a space to get exactly what you want.

I've added this as a recipe to the documentation https://mikefarah.gitbook.io/yq/recipes#deeply-prune-a-tree (well a slightly more general example)
