I saw this on the web a JSON library for C:
"JSON-C implements a reference counting object model that allows you to
easily construct JSON objects in C, output them as JSON formatted
strings and parse JSON formatted strings back into the C representation
of JSON objects."
I think I will change CGOS over to using JSON for the game records
:-) Just kidding!
But seriously, a simple system just for storing games would be to use
the same "tags" that the
xml version uses and use it pretty much like I have below - assuming
that is valid JSON.
Don't worry, I'm not going to push for yet another standard - but I do
hate SGF.
