JSON for Modern C++ 3.9.0 release has been announced for general availability and is now available with long-awaited features.<\/p>\n\n\n\n

JSON for Modern C++ is a library written is vanilla C++ 11 designed to feel and behave like a first-class citizen of the language.<\/p>\n\n\n\n

This JSON<\/a> tool adds four long-awaited features, some of which were requested five years ago. These are:<\/p>\n\n\n\n

• The parser functions have now an option to ignore \/\/<\/strong> and \/* *\/<\/strong> style comments even though comments are not officially part of the JSON specification.<\/li>
• Preservation of the insertion order of object keys through the new type nlohmann::ordered_json as a <\/em>drop-in replacement for nlohmann::json<\/em>.<\/li>
• Implicit conversions can now be switched off with a CMake<\/a> or preprocessor option to prevent unexpected behavior.<\/li>
• The mapping between user-defined types and JSON can now be expressed using convenience macros by just listing the names of the member variables to read\/write.<\/li><\/ul>\n\n\n\n

  Other highlights in this JSON library include added high-precision number support for UBJSON for integers larger than 9223372036854775807 (LLONG_MAX)<\/strong>. The code now compiles with Clang on Windows.<\/p>\n\n\n\n
