Hi Yves,

You know, I think the easiest way to achieve what you described, is to 
write your C++ scripts with input arguments.

Other than that, maybe you can incorporate a third-party JSON parser such 
as RapidJSON to parse custom JSON files in your scripts, if it is necessary.

Thank you,
Ruochun
