0.99.3a

Changes

The json initializer-list constructor has been removed, it gives inconsistent results when an initializer has zero elements, or one element of the type being initialized (json). Please replace

json j = {1,2,3} with json j = json::array{1,2,3}, and

json j = {{1,2,3},{4,5,6}} with json j = json::array{json::array{1,2,3},json::array{4,5,6}}

• Initializer-list constructors are now supported in json::object as well as json::array, e.g.

json j = json::object{{"first",1},{"second",json::array{1,2,3}}};

• json::any has been deprecated and will be removed in the future
• The json method to_stream has been renamed to write, the old name is still supported.
• output_format object_array_block_option, array_array_block_option functions have been deprecated and replaced by
  object_array_split_lines, array_array_split_lines functions.

Enhancements

• A new method get_with_default, with return type that of the default, has been added to json
• A new template parameter, JsonTraits, has been added to the basic_json class template.
• New instantiations of basic_json, ojson and wojson, have been added for users who wish to preserve the alphabetical sort of parsed json text and to insert new members in arbitrary name order.
• Added support for json is<T>, as<T>, constructor, and assignment operator for any sequence container (std::array, std::vector, std::deque, std::forward_list, std::list) whose values are assignable to JSON types (e.g., ints, doubles, bools, strings, STL containers of same) and for associative containers (std::set, std::multiset, std::unordered_set, std::unordered_multiset.)
• Added static method null() to json class to return null value
• A new extension jsonx that supports serializing JSON values to JSONx (XML)
• json parser will skip bom in input if present

Fixes:

• Fixes to the jsonpath extension, including the union operator and applying index operations to string values
• Fixes to remove warnings and issues reported by VS2015 with 4-th warnings level, PVS-Studio static analyzer tool, and UBSAN.
