Unmarshal with indentation only indent the first level

[sunshine69]

Hi,

I tested it with standard json it works fine

package main

import (
    "encoding/json"
    "fmt"
    "log"
)

var (
// json = jsoniter.ConfigCompatibleWithStandardLibrary
)

func main() {
    data := `{"a": 23, "b":"value b", "c": {"d": "d value", "e": 544, "f":{"g": 43, "h": "value og h"}   } }`
    var v interface{}
    json.Unmarshal([]byte(data), &v)

    b, err := json.MarshalIndent(v, "", "   ")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(string(b))
}
/* output
{
   "a": 23,
   "b": "value b",
   "c": {
      "d": "d value",
      "e": 544,
      "f": {
         "g": 43,
         "h": "value og h"
      }
   }
}
*/

However the following does not produce sub level indentation

package main

import (
    "fmt"
    "log"

    jsoniter "github.com/json-iterator/go"
)

var (
    json = jsoniter.ConfigCompatibleWithStandardLibrary
)

func main() {
    fmt.Println("vim-go")
    data := `{"a": 23, "b":"value b", "c": {"d": "d value", "e": 544, "f":{"g": 43, "h": "value og h"}   } }`
    var v interface{}
    json.Unmarshal([]byte(data), &v)
    b, err := json.MarshalIndent(v, "", "   ")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(string(b))
}
/* output
{
   "a": 23,
   "b": "value b",
   "c": {
   "d": "d value",
   "e": 544,
   "f": {
   "g": 43,
   "h": "value og h"
}
}
}
*/

It does not looks nice for jsoniter part :D

Not sure how much effort to fix this or is it known bug but I wish that could be fixed.

Thanks

There is a bug for indent. Because the substream doesn't set idention with stream's idention.
In my fork https://github.com/simonwu-os/json-iterator-go/tree/owned, I fixed it.
You can try to use "github.com/simonwu-os/json-iterator-go v1.1.5 " to check the issue is fixed or not.

func (encoder *sortKeysMapEncoder) Encode(ptr unsafe.Pointer, stream *Stream) {
stream.WriteObjectStart()
mapIter := encoder.mapType.UnsafeIterate(ptr)
subStream := stream.cfg.BorrowStream(nil)
subStream.Attachment = stream.Attachment

///added by simon. fix sorted map with indent bug 2023.1.24
cur_idention := stream.indention
subStream.indention = cur_idention
///end of added 2023.1.24.

subIter := stream.cfg.BorrowIterator(nil)
}
