Replace two array properties in .yml files

[fbeaufume]

What problem are you trying to solve?

In all .yml files, I need to replace two "array" properties ("families" by "groups" and "members" by "users" in the next example).

Can this be achieved using org.openrewrite.yaml.ChangePropertyKey or other standard recipes ?

Sample input and expected output

Sample input:

application.families:
  - name: Name1
    members:
      - name: John
        age: 20
      - name: Jane
        age: 30
  - name: Name2
    members:
      - name: Thomas
        age: 40

Expected output:

application.groups:
  - name: Name1
    users:
      - name: John
        age: 20
      - name: Jane
        age: 30
  - name: Name2
    users:
      - name: Thomas
        age: 40

What I tried

I tried using:

  # This changes nothing
  - org.openrewrite.yaml.ChangePropertyKey:
      oldPropertyKey: "application.families.members"
      newPropertyKey: "application.families.users"
  # This correctly replaces "families" by "groups"   
  - org.openrewrite.yaml.ChangePropertyKey:
      oldPropertyKey: "application.families"
      newPropertyKey: "application.groups"
  # This changes nothing
  - org.openrewrite.yaml.ChangePropertyKey:
      oldPropertyKey: "application.groups.members"
      newPropertyKey: "application.groups.users"

Hi! We recommend using unit tests to iterate more quickly to discover the exact combination of arguments that you'd need; See this example:
https://github.com/moderneinc/rewrite-recipe-starter/blob/a84848a8d70bfe20572d13d707898a47430eff12/src/test/java/com/yourorg/UpdateConcoursePipelineTest.java#L28-L56

You'll want to use spec.recipeFromResources or spec.recipeFromYaml to make it easier to use the yaml format as seen above.

Beyond that we recommend looking at existing recipe examples, for instance our recipe modules for

• rewrite-github-actions
• rewrite-gitlab

If you've found a bug, or have a runnable test that you can't get going then we can have a look, or join our Slack to ask questions.

Beyond that I don't have a lot of time to answer questions in issues here; my gut feeling says you're missing something between groups.members, as members is an array, not a direct property of groups.

With that I hope you don't mind me closing the issue; there's at this moment nothing actionable for us to do in terms of code changes.
