How to print full json with bigint/bigdec without quotes ?

[ghost]

Suppose this json:

std::vector<uint8_t> v;
    cbor::cbor_bytes_encoder encoder(v);
    encoder.begin_array(); // indefinite length outer array
    encoder.string_value("foo");
    encoder.byte_string_value(byte_string({'b','a','r'}));
    encoder.string_value("-18446744073709551617", semantic_tag::bigint);
    encoder.end_array();
    encoder.flush();
    json j = cbor::decode_cbor<json>(v);

    std::cout<<"json bigint test: "<<j[2].as<jsoncons::bigint>()<<std::endl;
    std::cout<<"pretty: "<<pretty_print(j)<<std::endl;
}

output:

json bigint test: -18446744073709551617  //<<ok
pretty: [
    "foo", 
    "YmFy", 
    "-18446744073709551617", //<< not ok
]

I want the json to be printed this way (this how python libs prints it, using pyarrow):

pretty: [
    "foo", 
    "YmFy", 
    -18446744073709551617,
]

Like this:

json_options options;
options.bigint_format(bigint_chars_format::number);

std::cout << "pretty: " << pretty_print(j, options) << std::endl;

great, thanks!
I see it also works for bigdec !

@danielaparker however in parsing json I see it works for bigint but not for bigdec, test example:

   void read_test() {
     json book4 = json::parse(R"(
    {
        "bigint" : 123456789012345678901234567890123456,
        "bigdec" : 1.123456789012345678901234567890123456
    }
    )");

           json_options options;
        options.bigint_format(bigint_chars_format::number);

        std::cout<<"pretty: "<<pretty_print(book4, options)<<std::endl;

   }

output:

pretty: {
    "bigdec": 1.1234567890123457, 
    "bigint": 123456789012345678901234567890123456, 
}

notice that bigdec was cut on digit number 18
is it a bug? or I need more options?

ok I succeded by passing the below to the parser:

options.lossless_number(true);
