loose match with get()

[podhmo]

Transform the data something like below to the last example.

{
  "xxx": {
     "mappings": {
          "x": { ... },
          "y": { ... }
     }
  }
}

or

{
  "zzz": {
     "mappings": {
          "x": { ... },
          "z": { ... }
     }
  }
}

transformed

{"xxx" : {"mappings": {"x": {}, "y": {}}}}

[podhmo]

So, something like {k: {} for k in get("*/mappings").keys()}.

[podhmo]

already supported this.

$ jqfpy '{k: {} for k in get("*/mappings").keys()}' /tmp/x.json
{
  "x": {},
  "y": {}
}

then, /tmp/x.json

{
  "xxx": {
    "mappings": {
      "x": {
        "xxx": "xxx"
      },
      "y": {
        "yyy": "yyy"
      }
    }
  }
}
