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 astd::list
for your arrays or anstd::unordered_map
for your objects. The specializationjson
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
, andconst_reverse_iterator
), comparison functions,swap()
,size()
,max_size()
, andempty()
member functions. - Added: The class uses user-defined allocators which default to
std::allocator
, but can be templated via parameterAllocator
. - Added: To simplify pretty-printing, the
std::setw
stream manipulator has been overloaded to set the desired indentation. Pretty-printing a JSON objectj
is as simple asstd::cout << std::setw(4) << j << '\n'
. - Changed: The type
json::value_t::number
is now calledjson::value_t::number_integer
to be more symmetric compared tojson::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).
