MsgPuck is a compact and efficient MessagePack serialization library:

• Zero-cost abstractions and zero overhead
• Clean and readable C code ready to use
• Easy to incorporate into your project
• Fully documented and covered by unit tests
• Liberal license (BSD-2)

MsgPuck is stable, which means it have been used in production without serious bugs for quite a while now. The library is fully documented and covered by unit tests.

Please feel free to file a ticket if your have a problem or a question.

Encoding:

char buf[1024];
char *w = buf;
w = mp_encode_array(w, 4);
w = mp_encode_uint(w, 10);
w = mp_encode_str(w, "hello world", strlen("hello world"));
w = mp_encode_bool(w, true);
w = mp_encode_double(w, 3.1415);

Validating:

const char *end = buf + xx;
const char *b = buf;
int rc = mp_check(&b, end);
assert(rc == 0);
assert(b == end);

Decoding:

uint32_t size;
uint64_t ival;
const char *sval;
uint32_t sval_len;
bool bval;
double dval;
const char *r = buf;
size = mp_decode_array(&r);
/* size is 4 */
ival = mp_decode_uint(&r);
/* ival is 10; */
sval = mp_decode_str(&r, &sval_len);
/* sval is "hello world", sval_len is strlen("hello world") */
bval = mp_decode_bool(&r);
/* bval is true */
dval = mp_decode_double(&r);
/* dval is 3.1415 */
assert(r == w);

You need a C89+ or C++03+ compatible compiler to use msgpuck. Add this project as a submodule or just use libmsgpuck-dev package.

MsgPuck is designed to be fully embedded to your application by a C/C++ compiler. However, some functions require auxiliary static tables which should be expanded somewhere in a compilation unit (*.c or *.cc file). Please link libmsgpuck.a to your binary to avoid problems with unresolved symbols.
