Recursively search for keys and apply custom sort

[jacobbednarz]

I have the following working to give me a predefined sort order with the remainder keys at the end.

$ yq '.methods |= pick( (["get", "list", "create", "update", "delete"] + keys) | unique)' example_sort_2.yaml

Before

methods:
  create: post /foo
  delete: delete /foo/{id}
  foo: get /
  bar: get /foo
  get: get /foo/{id}
  list: get /foo
  update: put /foo/{id}

After

methods:
  get: get /foo/{id}
  list: get /foo
  create: post /foo
  update: put /foo/{id}
  delete: delete /foo/{id}
  foo: get /
  bar: get /foo

However, I need to apply it recursively and I don't always know what level the .methods will be at. Any guidance on the best approach to traversing to find .methods and modify it regardless of nesting level?

Full example

foo:
  subresources:
    bar:
      methods:
        create: post /bar
        bar: get /bar
    baz:
      methods:
        delete: delete /baz
        get: get /baz
        create: post /baz
        update: put /baz
    qux:
      methods:
        list: get /qux
        create:
          endpoint: post /qux
        delete: delete /qux
        get: get /qux
        update: put /qux
quux:
  methods:
    list: get /quux
    create: post /quux
    delete: delete /quux
    get: get /quux
    update: put /quux

Expected outcome

foo:
  subresources:
    bar:
      methods:
        create: post /bar
        bar: get /bar
    baz:
      methods:
        get: get /baz
        create: post /baz
        update: put /baz
        delete: delete /baz
    qux:
      methods:
        list: get /qux
        get: get /qux
        create:
          endpoint: post /qux
        update: put /qux
        delete: delete /qux
quux:
  methods:
    get: get /quux
    list: get /quux
    create: post /quux
    update: put /quux
    delete: delete /quux

I did try with .. | select(has("methods")) however, that is giving some unexpected output (basically each iteration and nesting level) instead of just the thing i'm looking to update adding to the confusion.

You've got the right idea with .. | select(has("methods")) - sounds like you were probably just missing brackets (and so it was expanding everything and then, separately, updating).

yq '(.. | select(has("methods")) | .methods) |= pick( (["get", "list", "create", "update", "delete"] + keys) | unique)' file.yaml

Ah, good eye. I totally missed that. Thanks for the nudge!
