json

JSON library written with C++ features
简体中文 | English

Preface

Why write such a JSON library? github currently has a lot of large JSON parsing library, such as RapidJSON, jsoncpp, nlohmann_json, but due to history and other force majeure reasons, they have their own shortcomings and shortcomings, a variety of a wide range of code pile up, resulting in maintenance difficulties, I am committed to creating a code the most simple, fast, portable JSON library. Fast, portable JSON library.

Features

  1. a hundred polished API
  2. use std::variant for operations, memory-friendly
  3. has a slightly higher efficiency than nlohmann
  4. The code follows Google C++ Style

Usage

  1. add json.cpp and json.h to your project
  2. adjust the project's language standard to c++17 or newer
  3. Include json.h in your .c or .cpp file

Documentation

Main classes

  • Value Used to store, query and modify JSON data
  • Parser Used to parse a JSON string into Value
Parser p.
Value v.
if (!p.parse(s, v))
	cout << p.getError() << endl.
  • Writer Used to serialize Value objects into JSON strings
Writer w.
Value v.
w.writeValue(v).
cout << w.getOutput() << endl.

Of course you can also use Value::dump() for this function
If you want to configure serialization mode, you have to use this example
