Unnamed objects support

[vlkv]

Hi!
Your example

class JSONExample
{
public:
    std::string text;
...
}

Serializes into {"JSONExample":{"text":"Hello JSON World"}}. Is it possible to serialize them into just
{"text":"Hello JSON World"} ? Suppose I need to serialize a vector of JSONExample instances, so after serialization I'd like to have:
[{"text":"Hello JSON World 1"}, {"text":"Hello JSON World 2"}]

Hello vlkv.

The example below produces this:

{ "vector_example": { "text": ["ve0", "ve1", "ve2"] } }

Which parts are you trying to eliminate?

This snippet is also valid JSON but has had the markup generated by the std::vector<> member removed.

{ "vector_example": ["ve0", "ve1", "ve2"] }

What is going to consume the JSON?

//-----------------------------------------------------------------------------
// test elementary vector example
class vector_example
{
public:
	// content gets streamed to JSON
	std::vector<std::string> text;
public:
	void serialize(JSON::Adapter& adapter)
	{
		// this pattern is required 
		JSON::Class root(adapter, "vector_example");
		// this is the last member variable we serialize so use the _T variant
		JSON_T(adapter, text);
	}
};

void test_vector()
{

	vector_example source;
	source.text.push_back("ve0");
	source.text.push_back("ve1");
	source.text.push_back("ve2");
	std::string json = JSON::producer<vector_example>::convert(source);
	vector_example sink = JSON::consumer<vector_example>::convert(json);
	//
	JSON::throw_if(0, source.text != sink.text, "test_vector failed");
}

Hello!
In your example, I'd like to be able to have
{ "text": ["ve0", "ve1", "ve2"] } instead of
{ "vector_example": { "text": ["ve0", "ve1", "ve2"] } }

Look, It's not the same behaviour that we have in JavaScript (it's from Chrome console):

var vector_example = {text: ["ve0", "ve1", "ve2"]};
JSON.stringify(vector_example);
>>> "{"text":["ve0","ve1","ve2"]}"

I really want to have a functionality in c++ that provides golang https://blog.golang.org/json-and-go

Hello @vlkv ,

Did you get any solutions of your problem as I am also getting the same issue, Please let me know if you have any solutions.

Thanks in advance.

@pmehul55 what is going to consume your JSON?

Thanks for your reply. I am getting this string after performing below step

std::string json = JSON::producer<Request_Model>::convert(request);
std::cout << json;
{
"": {
"UserName": "abc",
"Password": "abc",
"MobileInfo": {
"AppVersion": "2.0",
MobileOSVersion: "iOS"
},
"ID": 1
}
}

How can I get below string instead of extra { "" this brackets

{
"UserName": "abc",
"Password": "abc",
"MobileInfo": {
"AppVersion": "2.0",
MobileOSVersion: "iOS"
},
"ID": 1
}

Thanks
