jazzml is a lightweight package to decode both json and yaml documents.
It does so by allowing the user to first specify a Decoder and then apply it to a json/yaml document.
A Decoder can be viewed as a specification of the expected structure of a json/yaml document.
This 2 step strategy brings some level of implicit checking. That is, if a document structure does not conform to the Decoder, the parsing fail.
Other nice features of jazzml include the possibility to define Decoders for recursive data structures and to dynamically choose a Decoder based on some specific value defined by the json/yaml document.
You'll find a more complete documentation on readthedocs.io
I hope you'll enjoy it.
