JSON without overhead

This compact library provides functions for loading, manipulating, and saving JSON data at maximum throughput.

High performance and reliability achieved by:

• Applying modern C++ design practices for top efficiency.
• Not using any third-party libraries, eliminating integration complexity.
• Keeping the code concise and readable, to ease in debugging.

It maintains compliance with the RFC 8259 JSON standard.

Usage example

Loading JSON from a file test.json

JSON::Object obj;
JSON::Result result = JSON::loadFromFile("C:/test.json", obj);

The JSON::Object-class holds a tree of objects, arrays, and values corresponding to the document structure.
In the above example, obj becomes the document root. If the input file is standard JSON, obj will contain a nested JSON object or array, or a single value.
Meaning that obj[0] is the first structure in the JSON text, and its children are the nested data.

The JSON::Result enum has many possible error codes, but OK is always returned on success.

if (result == JSON::Result::OK)
{
  // successfully parsed JSON document
}

Serialize to text

To dump a JSON::Object as a string, simply call the function. This will reformat the content as human-readable text
(alternatively toString(false), for compact JSON without whitespace).

std::string jstr = obj.toString();

UTF-16 and UTF-32 compatibility is planned, but currently only UTF-8 is supported. The IETF standard recommends using UTF-8, but it does not explicitly disallow the other encodings in all circumstances, thus, lacking support could be considered mildly non-compliant.

Integration with a glTF loader-writer library is planned.
