json-c v0.10 Release Notes

Release Date: 2012-05-31 // almost 12 years ago
    • Add a json_object_to_json_string_ext() function to allow output to be formatted in a more human readable form.
    • Add json_object_object_get_ex(), a NULL-safe get object method, to be able to distinguish between a key not present and the value being NULL.
    • Add an alternative iterator implementation, see json_object_iterator.h
    • Make json_object_iter public to enable external use of the json_object_object_foreachC macro.
    • Add a printbuf_memset() function to provide an efficient way to set and append things like whitespace indentation.
    • Adjust json_object_is_type and json_object_get_type so they return json_type_null for NULL objects and handle NULL passed to json_objct_object_get().
    • Rename boolean type to json_bool.
    • Fix various compile issues for Visual Studio and MinGW.
    • Allow json_tokener_parse_ex() to be re-used to parse multiple object. Also, fix some parsing issues with capitalized hexadecimal numbers and number in E notation.
    • Add json_tokener_get_error() and json_tokener_error_desc() to better encapsulate the process of retrieving errors while parsing.
    • Various improvements to the documentation of many functions.
    • Add new json_object_array_sort() function.
    • Fix a bug in json_object_get_int(), which would incorrectly return 0 when called on a string type object. Eric Haszlakiewicz
