Fortunately, there's a better way: + +```cpp +// create a person +ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60}; + +// conversion: person -> json +json j = p; + +std::cout << j << std::endl; +// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"} + +// conversion: json -> person +ns::person p2 = j; + +// that's it +assert(p == p2); +``` + +#### Basic usage + +To make this work with one of your types, you only need to provide two functions: + +```cpp +using nlohmann::json; + +namespace ns { + void to_json(json& j, const person& p) { + j = json{{"name", p.name}, {"address", p.address}, {"age", p.age}}; + } + + void from_json(const json& j, person& p) { + p.name = j["name"].get(); + p.address = j["address"].get(); + p.age = j["age"].get(); + } +} // namespace ns +``` + +That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called. +Likewise, when calling `get()`, the `from_json` method will be called. + +Some important things: + +* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined). +* When using `get()`, `your_type` **MUST** be [DefaultConstructible](http://en.cppreference.com/w/cpp/concept/DefaultConstructible). (There is a way to bypass this requirement described later.) + +#### How do I convert third-party types? + +This requires a bit more advanced technique. But first, let's see how this conversion mechanism works: + +The library uses **JSON Serializers** to convert types to json. +The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](http://en.cppreference.com/w/cpp/language/adl)). + +It is implemented like this (simplified): + +```cpp +template +struct adl_serializer { + static void to_json(json& j, const T& value) { + // calls the "to_json" method in T's namespace + } + + static void from_json(const json& j, T& value) { + // same thing, but with the "from_json" method + } +}; +``` + +This serializer works fine when you have control over the type's namespace. However, what about `boost::optional`, or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`... + +To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example: + +```cpp +// partial specialization (full specialization works too) +namespace nlohmann { + template + struct adl_serializer> { + static void to_json(json& j, const boost::optional& opt) { + if (opt == boost::none) { + j = nullptr; + } else { + j = *opt; // this will call adl_serializer::to_json which will + // find the free function to_json in T's namespace! + } + } + + static void from_json(const json& j, boost::optional& opt) { + if (j.is_null()) { + opt = boost::none; + } else { + opt = j.get(); // same as above, but with + // adl_serializer::from_json + } + } + }; +} +``` + +#### How can I use `get()` for non-default constructible/non-copyable types? + +There is a way, if your type is [MoveConstructible](http://en.cppreference.com/w/cpp/concept/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload: + +```cpp +struct move_only_type { + move_only_type() = delete; + move_only_type(int ii): i(ii) {} + move_only_type(const move_only_type&) = delete; + move_only_type(move_only_type&&) = default; + + int i; +}; + +namespace nlohmann { + template <> + struct adl_serializer { + // note: the return type is no longer 'void', and the method only takes + // one argument + static move_only_type from_json(const json& j) { + return {j.get()}; + } + + // Here's the catch! You must provide a to_json method! Otherwise you + // will not be able to convert move_only_type to json, since you fully + // specialized adl_serializer on that type + static void to_json(json& j, move_only_type t) { + j = t.i; + } + }; +} +``` + +#### Can I write my own serializer? (Advanced use) + +Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples. + +If you write your own serializer, you'll need to do a few things: + +* use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`) +* use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods +* use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL + +Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL. + +```cpp +// You should use void as a second template argument +// if you don't need compile-time checks on T +template::type> +struct less_than_32_serializer { + template + static void to_json(BasicJsonType& j, T value) { + // we want to use ADL, and call the correct to_json overload + using nlohmann::to_json; // this method is called by adl_serializer, + // this is where the magic happens + to_json(j, value); + } + + template + static void from_json(const BasicJsonType& j, T& value) { + // same thing here + using nlohmann::from_json; + from_json(j, value); + } +}; +``` + +Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention: + +```cpp +template +struct bad_serializer +{ + template + static void to_json(BasicJsonType& j, const T& value) { + // this calls BasicJsonType::json_serializer::to_json(j, value); + // if BasicJsonType::json_serializer == bad_serializer ... oops! + j = value; + } + + template + static void to_json(const BasicJsonType& j, T& value) { + // this calls BasicJsonType::json_serializer::from_json(j, value); + // if BasicJsonType::json_serializer == bad_serializer ... oops! + value = j.template get(); // oops! + } +}; +``` + ### Binary formats (CBOR and MessagePack) Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports [CBOR](http://cbor.io) (Concise Binary Object Representation) and [MessagePack](http://msgpack.org) to efficiently encode JSON values to byte vectors and to decode such vectors. @@ -521,7 +749,7 @@ The following compilers are currently used in continuous integration at [Travis] The class is licensed under the [MIT License](http://opensource.org/licenses/MIT): -Copyright © 2013-2016 [Niels Lohmann](http://nlohmann.me) +Copyright © 2013-2017 [Niels Lohmann](http://nlohmann.me) Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the “Software”), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: @@ -546,7 +774,7 @@ I deeply appreciate the help of the following people. - [Eric Cornelius](https://github.com/EricMCornelius) pointed out a bug in the handling with NaN and infinity values.
