json

The module json_mod (stored in json.f90) is a module used for reading and writing JSON files. JSON (stands for "JavaScript Object Notation") is a file format that stores data in key-value pairs (like a Python dictionary). JSON files are used for input and output with MachLine.

This module makes extensive use of pointers for storing and referencing JSON objects within Fortran. Some good information on pointers in Fortran may be found here.
