Feature Request: python style json string

[lwabish]

Is it possible to output json string exactly like python json.dumps?

[tidwall]

I'm not familiar with that format. What's different?

[lwabish]

In my case, python json strings vs go json string has an obvious difference at spaces, for example:
{"a": 1} for python
{"a":1} for go

This is usually not a problem if this json is for deserializing. In my case, the json string is used for LLM which may be sensitive to any letters even if spaces within json string.

But it seems not easy to let go json.Marshal output python style json string, as well as this repo currently, I think?

I have a quick implement but not graceful, PTAL, would be greate if you can give me some advice on it

func MarshalPythonStyle(v interface{}) ([]byte, error) {
	
	compactJSON, err := json.Marshal(v)
	if err != nil {
		return nil, err
	}

	
	var buffer bytes.Buffer
	var inString bool = false

	for i, r := range compactJSON {
		
		char := byte(r)

		if char == '"' {
			
			if i > 0 && compactJSON[i-1] == '\\' {
				
			} else {
				
				inString = !inString
			}
		}

		
		buffer.WriteByte(char)

		
		if !inString {
			if char == ':' || char == ',' {
				
				buffer.WriteByte(' ')
			}
		}
	}

	return buffer.Bytes(), nil
}
