What is ARD? See here.

The latest stable release of this library is available on PyPi:

python -m pip install ard

This library has three main features:

1. Allows you to easily transmit ARD in several formats: YAML, JSON, XML, and CBOR. Supports both encoding and decoding. Included is an ardconv CLI tool that can convert between all formats.
2. Enable support for decoding YAML with complex keys. As it stands, the otherwise excellent ruamel.yaml library will choke on complex keys.
3. Support for ARD-compatible extensions to JSON (CJSON). This allows for round-tripping ARD through JSON without losing type information, including support for integers, byte arrays, and maps with non-string keys.

Python's dict does not support un-hashable keys, making it difficult to work with complex keys. For this reason we provide the ard.Map class, which does support un-hashable keys and is otherwise a drop-in replacement for dict. It will be used automatically when decoding, if necessary.

Documentation is a work in progress! For now check out test.py for example use.
