Any (working) JSON library for D2?

[Adam D. Ruppe]

Oh, wait a minute, you were doing from json, not to json.

Try this on for size. It converts from a std.json.JSONValue
to a std.variant.Varaint, which is quite a bit simpler to use.

======

import std.variant;
import std.json;

Variant jsonToVariant(string json) {
	auto decoded = parseJSON(json);
	return jsonValueToVariant(decoded);
}

Variant jsonValueToVariant(JSONValue v) {
	Variant ret;

	final switch(v.type) {
		case JSON_TYPE.STRING:
			ret = v.str;
		break;
		case JSON_TYPE.INTEGER:
			ret = v.integer;
		break;
		case JSON_TYPE.FLOAT:
			ret = v.floating;
		break;
		case JSON_TYPE.OBJECT:
			Variant[string] obj;
			foreach(k, val; v.object) {
				obj[k] = jsonValueToVariant(val);
			}

			ret = obj;
		break;
		case JSON_TYPE.ARRAY:
			Variant[] arr;
			foreach(i; v.array) {
				arr ~= jsonValueToVariant(i);
			}

			ret = arr;
		break;
		case JSON_TYPE.TRUE:
			ret = true;
		break;
		case JSON_TYPE.FALSE:
			ret = false;
		break;
		case JSON_TYPE.NULL:
			ret = null;
		break;
	}

	return ret;
}
