Concise Binary Object Representation (CBOR) for Pharo
# CBOR
[](https://github.com/svenvc/CBOR/actions/workflows/CI.yml)
Concise Binary Object Representation (CBOR) is a binary data serialization format.
CBOR is based on the JSON data model: a number of primitive types (integers, floats, booleans, strings and null), lists and maps (which represent objects or structures).
Being binary, CBOR is more efficient than JSON, which is text based.
CBOR also supports binary data and optional extensions (called tags).
This implementation has native support for string and epoch based timestamps (DateAndTime) and big integers (Integer).
This project contains encoding/decoding support for the half-precision, IEEE 754 16-bit (binary16) floating-point format.
## Examples
```Smalltalk
(CBORReader on: (ByteArray readHexFrom: 'a201020304') readStream) next.
CBORReader decode: #[162 1 2 3 4].
ByteArray streamContents: [ :out | (CBORWriter on: out) nextPut: { 1 -> 2. 3 -> 4 } asDictionary ].
CBORWriter encode: { 1 -> 2. 3 -> 4 } asOrderedDictionary.
```
