JSON for C

• C Header Only JSON implementation.

Notes

• Work in progress, everything is subject to change.
• Still lacking support for some features

Usage

Simply #include "json.h".

• Reading:
  You can do either:

hjson *json = jsonRead(your_file);

or

hjson *json = jsonParse(your_json_string, strlen(your_json_string));

Don't forget to free the memory once you are done:

jsonFree(json);

• Writing:
  In a similar fashion, pass your json pointer to jsonWrite():

if(jsonWrite(your_file_path, json) != 0) printf("failed to save\n");

• Editing:
  A few functions are available to access the pointers or to manipulate the json list or objects in a simple way.
  Keep in mind the hjson structure represents a json value. For example, a hjson variable with the type JSONLIST will refers to a jlist structure which is pretty much an array of hjson pointers (in short: everything are hjson, the values contained in your list and the list itself).
  Here's a quick rundown:
  jsonAlloc - create a json object from a type and a pointer to the corresponding value.
  jsonFree - destroy the json object and free the memory from all values.
  jsonGet<Type> - multiple functions to access the pointer of the json object. If the type doesn't match (example: jsonGetInt on a JSONSTR value), a null pointer is returned.
  jsonIsNull - only for null values. Return 1 if null, 0 if it's an error.
  jsonListSize - returns the size of a list value or 0 if it's not a list.
  jsonListAppend - append a value to the list, returns -1 if it's not a list.
  jsonListSet - set the value at the specified position in a list, returns -1 if it's not a list or if the position is incorrect.
  jsonObjGet - retrieve a pointer the value at the specified key in an object, returns null if it's not an object or if the key is incorrect.
  jsonObjSet - set the value with the specified key in an object, returns null if it's not an object or if an error happens.
  jsonObjDel - delete the value with the specified key in an object, returns -1 if it's not an object.
