CBOR11

A simple CBOR implementation written in C++. It decodes any valid CBOR, but will always encode in the shortest definite form. Integers and floating-point numbers are kept as distinct types when encoding. Tags are parsed and exposed to the application. They are not interpreted in any way however.

Types

• Unsigned integer (unsigned long long, unsigned long, unsigned int, unsigned short, long long, long, int and short)
• Negative integer (long long, long, int and short)
• Byte string (cbor::binary/std::vector<unsigned char>)
• Text string (cbor::string/std::string)
• Array of items (cbor::array/std::vector<cbor>)
• Map of pairs of items (cbor::map/std::map<cbor,cbor>)
• Tagged values (cbor::tagged (tag, value))
• Simple values (cbor::simple, bool and nullptr_t)
• Floating-point numbers (double and float)

Usage

#include "cbor11.h"

// Create complicated CBOR with simple code thanks to C++11
cbor item = cbor::array {
	12,
	-12,
	u8"イチゴ",
	cbor::binary {0xff, 0xff},
	cbor::array {"Alice", "Bob", "Eve"},
	cbor::map {
		{"CH", "Switzerland"},
		{"DK", "Denmark"},
		{"JP", "Japan"}
	},
	cbor::simple (0),
	false,
	nullptr,
	cbor::undefined,
	1.2
};

// Convert to diagnostic notation for easy debugging
std::cout << cbor::debug (item) << std::endl;

// Encode
cbor::binary data = cbor::encode (item);

// Decode (if invalid data is given cbor::undefined is returned)
item = cbor::decode (data);

// Read from any instance of std::istream
item.read (std::cin);

// Write to any instance of std::ostream
item.write (std::cout);
