the diff in the cli isn't showing certain fields which should be shown. This is because when array order is changed it will be treated as struct type of diff.movestruct. This struct isn't handled in the switch condition which prints the diff. ascii.go. Thus it goes into the default case where the data(moved) isn't printed and an unhandled error is returned.

Same issue has been raised in this repo as well yudai/gojsondiff#39.

In the above issue the response was this:-

    {
           "bidid": "test bid id",
           "id": "some-request-id",
           "nbr": 0,
           "seatbid": [
             0: {
               "bid": [
                 1: {
                   "id": "rubicon-bid",
                   "impid": "",
                   "price": 0
                 },
                 2: {
                   "id": "appnexus-bid",
                   "impid": "",
                   "price": 0
                 },
               ],
               "seat": "seat-id"
             }
           ]
         }

and this is the difference shown by the tool.

The field

2: {
                   "id": "appnexus-bid",
                   "impid": "",
                   "price": 0
                 },

is missing in the diff viewer.
