EzJSON

A Fast and Minimalist JSON Library

EzJSON is a fast and minimalist JSON library.

Installation

EzJSON need the compiler to support C++11. You can include the library source file in your project, or you can run make command to build a shared library (recommanded).

Usage

As it name suggests, EzJSON is really easy to use. Use JSON string to contruct an EzJSON object, then you can access it like an array / map.

Ez::JSON j("[1, {\"foo\" : [3, 4]}, 2]");
std::cout << j[1]["foo"].asDouble();

You can modify the JSON tree by set() and remove() method.

Ez::JSON j("{}");
j.set("foo", "[1, 2, 3, 4]");
j["foo"].remove(2);

EzJSON has a baked-in pretty printing functionality.

Ez::JSON j("[1, {\"foo\" : [3, 4]}, 2]");
std::cout << j.serialize();

All EzJSON exceptions are derived from std::exception.

try
{
	Ez::JSON j("{");
}
catch (const std::exception& e)
{
	// get the error message
	std::cout << e.what();
}

Performance

Inspired by rapidjson, EzJSON use a custom allocator to dramatically speed up the parsing process. It's approximately 6x faster than dropbox's json11, and it took only 1.3 second for EzJSON to build complete AST for a very large (185MB) JSON file.
