{} and [] causes parser error.

[smoofproof]

Hey there!

{} and [] should be a valid empty JSON object/array. Instead, it creates - parse error - unexpected end of input.

Example:

nlohmann::json j;

std::stringstream ss("{}");

ss >> j;

Greetings

What version have you tried? I've tried both {} and [] and got expected result

#include <sstream>
#include <iostream>
#include "json.hpp"

using namespace nlohmann;

int main() {
    try {
        json j;
        std::stringstream ss("[]");
        ss >> j;
        std::cout << "all good" << std::endl;
    } catch(std::exception&) {
        std::cout << "no luck" << std::endl;
    }
}

There was a bug with too short inputs in 2.0.6. Please try 2.0.7, see https://github.com/nlohmann/json/releases/tag/v2.0.7
