MessagePack serialization library for various Smalltalk dialects.
- Squeak
- Pharo
- VisualWorks
- VA Smalltalk
- Dolphin Smalltalk
- GNU Smalltalk (Beta)

## How to use ##
### Serialization ###
```Smalltalk
MpMessagePack pack:
```
or:
```Smalltalk
messagePacked
```
### Deserialization ###
```Smalltalk
MpMessagePack unpack: msgpackBytes
```
or:
```Smalltalk
Object fromMessagePack: msgBytes
```
### Samples ###
```Smalltalk
map := Dictionary new.
map at: 'someArray' asByteArray put: #(1 2.2 #[3 4 5]).
packed := map messagePacked.
(Object fromMessagePack: packed) inspect.
```
```Smalltalk
writeStream := WriteStream on: ByteArray new.
encoder := MpEncoder on: writeStream.
encoder nextPut: 1.
encoder nextPut: #(2 3).
dic := Dictionary new.
dic at: 4 put: 5.
encoder nextPut: dic.
encoder nextPut: 'four' asByteArray.
bytes := encoder contents.
readStream := ReadStream on: bytes.
decoder := MpDecoder on: readStream.
[decoder atEnd] whileFalse: [
Transcript cr; show: decoder next printString
]
```
### How to install
Please read [HowToInstall.md]().
### Loading the latest development version
#### Squeak 4
```Smalltalk
Installer squeaksource
project: 'MessagePack';
install: 'ConfigurationOfMessagePack'.
(Smalltalk at: #ConfigurationOfMessagePack) project development load
```
#### Pharo & Squeak 5+
```Smalltalk
Metacello new
baseline: 'MessagePack';
repository: 'github://msgpack/msgpack-smalltalk:develop/repository';
load.
```
You might need ```MpTypeMapper initializeAll ``` on new encoder/decoder-related updates.
#### Limitation on Squeak 5+
Starting with Squeak 5 and 6, DateAndTime only supports microsecond precision. Because of this, nanosecond values are not properly decoded as DateAndTime.
Two unit tests (testPackUnpackTimestamp64, 96) fail on Squeak 5 and 6.
