crash on empty ifstream

[Chrjstoph]

if file is empty, parsing crashes.

[nlohmann]

Which version are you using?

[Chrjstoph]

the latest, (of what?)

[nlohmann]

I meant the version of the library. In the develop branch, the following program (and an empty file empty.json)

#include <json.hpp>
#include <fstream>

using json = nlohmann::json;

int main()
{
    std::ifstream f_empty("empty.json");
    json j = json::parse(f_empty);
    std::cout << j << std::endl;
}

aborts with

libc++abi.dylib: terminating with uncaught exception of type nlohmann::detail::parse_error: 
[json.exception.parse_error.101] parse error at 2: parse error - unexpected end of input

Apart from the file position (2) this seems to make sense. What did you expect?

[Chrjstoph]

you are right, I was confusing it with an empty json “”.
