I have a query regarding nlohmann::basic_json::basic_json

[sonulohani]

Hi @nlohmann ,

While i was understanding the json code, I've got involved into a question. In this link:- https://nlohmann.github.io/json/classnlohmann_1_1basic__json_ab5dfd9a2b2663b219641cb7fe59b6da2.html#ab5dfd9a2b2663b219641cb7fe59b6da2 in the ctor "basic_json" I want to pass type_deduction as false. How can i do that.

[nlohmann]

You could try:

auto j = basic_json({{"foo", "bar"}}, false);

@nlohmann Thank you.

Hi @nlohmann ,

I am doing like this:-

using nlohmann::json;
json j_array = json({13, 29, 3, {{"one", 1}, {"two", 2}}, true, false, {1, 2, 3}, "foo", "baz"}, false);

But the value of type_deduction is still true.

[nlohmann]

I guess you then also need to pass a value for manual_type. These are actually internal parameters.

Hi @nlohmann,

I got it now. Thanks for the answer. Yeah those were internal parameters.

[nlohmann]

If you just want to enforce that an array is created, it is better to make this explicit by using this function: https://nlohmann.github.io/json/classnlohmann_1_1basic__json_aa80485befaffcadaa39965494e0b4d2e.html#aa80485befaffcadaa39965494e0b4d2e (it uses the other constructor internally)

@sonulohani Can I close this issue?

[sonulohani]

@nlohmann Yeah sure. Thank you very much
