`msgpack` for C/C++
===================
Version 3.0.1 [![Build Status](https://travis-ci.org/msgpack/msgpack-c.svg?branch=master)](https://travis-ci.org/msgpack/msgpack-c) [![Build status](https://ci.appveyor.com/api/projects/status/8kstcgt79qj123mw/branch/master?svg=true)](https://ci.appveyor.com/project/redboltz/msgpack-c/branch/master)
It's like JSON but smaller and faster.
Overview
--------
[MessagePack](http://msgpack.org/) is an efficient binary serialization
format, which lets you exchange data among multiple languages like JSON,
except that it's faster and smaller. Small integers are encoded into a
single byte and short strings require only one extra byte in
addition to the strings themselves.
Example
-------
In C:
```c
#include <msgpack.h>
#include <stdio.h>
int main(void)
{
/* msgpack::sbuffer is a simple buffer implementation. */
msgpack_sbuffer sbuf;
msgpack_sbuffer_init(&sbuf);
/* serialize values into the buffer using msgpack_sbuffer_write callback function. */
msgpack_packer pk;
msgpack_packer_init(&pk, &sbuf, msgpack_sbuffer_write);
msgpack_pack_array(&pk, 3);
msgpack_pack_int(&pk, 1);
msgpack_pack_true(&pk);
msgpack_pack_str(&pk, 7);
msgpack_pack_str_body(&pk, "example", 7);
/* deserialize the buffer into msgpack_object instance. */
/* deserialized object is valid during the msgpack_zone instance alive. */
msgpack_zone mempool;
msgpack_zone_init(&mempool, 2048);
msgpack_object deserialized;
msgpack_unpack(sbuf.data, sbuf.size, NULL, &mempool, &deserialized);
/* print the deserialized object. */
msgpack_object_print(stdout, deserialized);
puts("");
msgpack_zone_destroy(&mempool);
msgpack_sbuffer_destroy(&sbuf);
return 0;
}
```
See [`QUICKSTART-C.md`](./QUICKSTART-C.md) for more details.
In C++:
```c++
#include <msgpack.hpp>
#include <string>
#include <iostream>
#include <sstream>
int main(void)
{
msgpack::type::tuple<int, bool, std::string> src(1, true, "example");
// serialize the object into the buffer.
// any classes that implements write(const char*,size_t) can be a buffer.
std::stringstream buffer;
msgpack::pack(buffer, src);
// send the buffer ...
buffer.seekg(0);
// deserialize the buffer into msgpack::object instance.
std::string str(buffer.str());
msgpack::object_handle oh =
msgpack::unpack(str.data(), str.size());
// deserialized object is valid during the msgpack::object_handle instance is alive.
msgpack::object deserialized = oh.get();
// msgpack::object supports ostream.
std::cout << deserialized << std::endl;
// convert msgpack::object instance into the original type.
// if the type is mismatched, it throws msgpack::type_error exception.
msgpack::type::tuple<int, bool, std::string> dst;
deserialized.convert(dst);
return 0;
}
```

Usage
-----
### C++ Header Only Library
When you use msgpack on C++03 and C++11, you can just add
msgpack-c/include to your include path:
g++ -I msgpack-c/include your_source_file.cpp
If you want to use C version of msgpack, you need to build it. You can
also install the C and C++ versions of msgpack.
### Building and Installing
#### Install from git repository
##### Using the Terminal (CLI)
You will need:
- `gcc >= 4.1.0`
- `cmake >= 2.8.0`
C and C++03:
$ git clone https://github.com/msgpack/msgpack-c.git
$ cd msgpack-c
$ cmake .
$ make
$ sudo make install
If you want to setup C++11 version of msgpack instead,
execute the following commands:
$ git clone https://github.com/msgpack/msgpack-c.git
$ cd msgpack-c
$ cmake -DMSGPACK_CXX11=ON .
$ sudo make install
#### GUI on Windows
Clone msgpack-c git repository.
$ git clone https://github.com/msgpack/msgpack-c.git
or using GUI git client.
e.g.) tortoise git https://code.google.com/p/tortoisegit/
1. Launch [cmake GUI client](http://www.cmake.org/cmake/resources/software.html).
2. Set 'Where is the source code:' text box and 'Where to build
the binaries:' text box.
3. Click 'Configure' button.
4. Choose your Visual Studio version.
5. Click 'Generate' button.
6. Open the created msgpack.sln on Visual Studio.
7. Build all.
