JSON for Modern C++

Version 1.0.0-rc1

  • Release date: 2015-07-26
  • MD5: fac5948417ed49bfd0852a0e9dd36935

Summary

The 1.0.0 release should be the first "official" release after the initial announcement of the class in January 2015 via reddit ("0.1.0") and a heavily overworked second version ("0.2.0") in February.

Changes

  • Changed: In the generic class basic_json, all JSON value types (array, object, string, bool, integer number, and floating-point) are now templated. That is, you can choose whether you like a std::list for your arrays or an std::unordered_map for your objects. The specialization json sets some reasonable defaults.
  • Changed: The library now consists of a single header, called json.hpp. Consequently, build systems such as Automake or CMake are not any longer required.
  • Changed: The deserialization is now supported by a lexer generated with re2c from file src/json.hpp.re2c. As a result, we strictly follow the JSON specification. Note neither the tool re2c nor its input are required to use the class.
  • Added: The library now satisfies the ReversibleContainer requirement. It hence provides four different iterators (iterator, const_iterator, reverse_iterator, and const_reverse_iterator), comparison functions, swap(), size(), max_size(), and empty() member functions.
  • Added: The class uses user-defined allocators which default to std::allocator, but can be templated via parameter Allocator.
  • Added: To simplify pretty-printing, the std::setw stream manipulator has been overloaded to set the desired indentation. Pretty-printing a JSON object j is as simple as std::cout << std::setw(4) << j << '\n'.
  • Changed: The type json::value_t::number is now called json::value_t::number_integer to be more symmetric compared to json::value_t::number_float.
  • Added: The documentation is generated with Doxygen and hosted at nlohmann.github.io/json. Every public member function is thoroughly described including an example which also can be tried online.
  • Added: The class is heavily unit-tested (3341774 assertions) and has a line coverage of 100%. With every commit, the code is compiled with g++ 4.9, g++ 5.0, Clang 3.6 (thanks to Travis CI), and Microsoft Visual Studio 14 2015 (thanks to AppVeyor).
