Support for MessagePack

[Matheus-Garbelini]

Hello, I use a lot JSON Arduino Library and would like to know if it's possible to modify manually the Deserializer and Serializer to support MessagePack (kinda of binary JSON). Currently, the MessagePack library for Arduino is very hard and not intuitive to use.

As Message Pack contains the same structure as JSON, but with specific bytes to indicate what comes next (float, object, array and so on), I was trying to understand how Deserializer works when decoding strings to float, integer, boolean, etc.

Do you think is viable to manually modify the Deserializer to recognize a Message Pack structure by modifying the existing functions to "think" it's decoding JSON, but instead is decoding Messa Pack?
(I could just get a message in MessagePack and Serialize it to JSON and then apply this library but that would be too inefficient.)
Thanks.

PS: The Serializer I think would be a lot easier to override the existing function to write MessagePack syntax as brackets and commas can be replaced with specific bytes.

Hi,

Support for MessagePack is definitely on the roadmap (see #358).
However, I need to change the API before, so it will be in 6.x.
I'm currently busy adding the very last changes to 5.x, so I cannot give you an ETA.

I'm sorry, I don't have any quick-fix solution.

Regards,
Benoit

@bblanchon thank you, in the meantime, I will try to get something running.
