JSON Library

An Implementation for RFC 7159 for parsing and generating JSON (JavaScript Object Notation) data.

Getting Started

This library parses and generates JSON data, facilitating data interchange between systems. Ideal for integrating with applications that require structured data communication.

Supported Platforms

• Windows: Visual Studio (MSVC)
• Linux: GCC or Clang
• MacOS: Xcode (Clang)

Prerequisites

• CMake 3.8 or later
• A C++ compiler compatible with CMake (e.g., MSVC, GCC, or Clang)

Building the Library

To compile the library, use the following steps:

mkdir build && cd build
cmake ..
make

On Windows, use:

mkdir build && cd build
cmake .. -G "Visual Studio 16 2019"
cmake --build . --config Release

Usage

#include "value.h"
#include <iostream>

int main() {
    // JSON input string
    std::string jsonString = R"({"temperature": 23.5, "unit": "Celsius", "valid": true})";

    // Parse the JSON string
    Json::Value json = Json::Value::FromEncoding(jsonString);

    // Validate parsing
    if (json.GetType() == Json::Value::Type::Invalid) {
        std::cerr << "Failed to parse JSON." << std::endl;
        return 1;
    }

    // Extract values
    double temperature = (double)json["temperature"];
    std::string unit = (std::string)json["unit"];
    bool isValid = (bool)json["valid"];

    // Print extracted values
    std::cout << "Temperature: " << temperature << " " << unit << std::endl;
    std::cout << "Valid: " << (isValid ? "Yes" : "No") << std::endl;

    return 0;
}
