Serialization:
auto json = Json({{"name", this->name},
{"age", this->age},
{"height", this->height}});
std::string str = json.serialize();Deserialization:
auto json = Json::parse("{\"age\": 69, \"height\": 1.95, \"name\": \"Foo\"}");
auto person = Person(json.value());
ASSERT(person.name == "Foo");
ASSERT(person.age == 69);
ASSERT(std::abs(person.height - 1.95) < 0.0001);This is how you can use the library to serialize a class:
class Person
{
public:
std::string name;
int age;
float height;
Person(const std::string& name, int age, float height)
: name(name), age(age), height(height) {}
Person(jp::Json& json)
{
this->from_json(json);
}
jp::Json to_json()
{
return jp::Json({{"name", this->name},
{"age", this->age},
{"height", this->height}});
}
void from_json(jp::Json& json)
{
this->name = std::get<std::string>(json["name"]);
this->age = std::get<int>(json["age"]);
this->height = std::get<float>(json["height"]);
}
};The library is just composed of one header and one cpp file so you
could copy-paste them in your project. Or you can add the library
to your build system in many ways, via a git submodule or CPM for
example.
To build the library:
cmake -Bbuild && cmake --build build
Build and run tests using the amazing valFuzz:
cmake -Bbuild -DCMAKE_BUILD_TYPE=Debug -DJP_BUILD_TESTS=on
cmake --build build
./build/json-please_tests --verbose
