It lets you exchange data among multiple languages like JSON. But it's faster and smaller. This package provides CPython bindings for reading and writing MessagePack data. ## Very important notes for existing users ### PyPI package name Package name on PyPI was changed from `msgpack-python` to `msgpack` from 0.5. When upgrading from msgpack-0.4 or earlier, do `pip uninstall msgpack-python` before `pip install -U msgpack`. ### Compatibility with the old format You can use `use_bin_type=False` option to pack `bytes` object into raw type in the old msgpack spec, instead of bin type in new msgpack spec. You can unpack old msgpack format using `raw=True` option. It unpacks str (raw) type in msgpack into Python bytes. See note below for detail. ### Major breaking changes in msgpack 1.0 * Python 2 * The extension module does not support Python 2 anymore. The pure Python implementation (`msgpack.fallback`) is used for Python 2. * Packer * `use_bin_type=True` by default. bytes are encoded in bin type in msgpack. **If you are still using Python 2, you must use unicode for all string types.** You can use `use_bin_type=False` to encode into old msgpack format. * `encoding` option is removed. UTF-8 is used always. * Unpacker * `raw=False` by default. It assumes str types are valid UTF-8 string and decode them to Python str (unicode) object. * `encoding` option is removed. You can use `raw=True` to support old format. * Default value of `max_buffer_size` is changed from 0 to 100 MiB. * Default value of `strict_map_key` is changed to True to avoid hashdos. You need to pass `strict_map_key=False` if you have data which contain map keys which type is not bytes or str. ## Install ``` $ pip install msgpack ``` ### Pure Python implementation The extension module in msgpack (`msgpack._cmsgpack`) does not support Python 2 and PyPy. But msgpack provides a pure Python implementation (`msgpack.fallback`) for PyPy and Python 2. ### Windows When you can't use a binary distribution, you need to install Visual Studio or Windows SDK on Windows. Without extension, using pure Python implementation on CPython runs slowly. ## How to use NOTE: In examples below, I use `raw=False` and `use_bin_type=True` for users using msgpack < 1.0. These options are default from msgpack 1.0 so you can omit them. ### One-shot pack & unpack Use `packb` for packing and `unpackb` for unpacking. msgpack provides `dumps` and `loads` as an alias for compatibility with `json` and `pickle`. `pack` and `dump` packs to a file-like object. `unpack` and `load` unpacks from a file-like object.
