JSON Toolkit is a swiss-army knife for JSON programming in modern C++. It comes with a built-in parser and growing support for standards such as JSON Schema, JSON Pointer, JSONL, and more.

Example

#include <sourcemeta/jsontoolkit/json.h>
#include <sourcemeta/jsontoolkit/jsonpointer.h>
#include <sstream>
#include <iostream>

int main()  {
    // Creating JSON using parse
    sourcemeta::jsontoolkit::JSON document =
        sourcemeta::jsontoolkit::parse(R"JSON({
            "name": "John Doe",
            "age": 20,
            "address": "zxy"
        })JSON");

    // JSON pointer for the name property
    const sourcemeta::jsontoolkit::Pointer name_pointer{"name"};
    // A new JSON document for the name
    const sourcemeta::jsontoolkit::JSON name_value{"Johnny Doe"};
    // Updating the value of the name using JSON pointer
    sourcemeta::jsontoolkit::set(document, name_pointer, name_value);
    sourcemeta::jsontoolkit::prettify(document, std::cout);
    std::cout<<"\n";

    // The above program will print the following to standard output:
    //output :
    //    {
    //       "address": "zxy_with_bar",
    //       "age": 21,
    //       "name": "xyz_with_foo"
    //    }
}
