Dear Community, Please let me share with you a C++ library for parsing/generating JSON. Project overview: [[http://hutorny.in.ua/projects/cojson-a-json-parser-for-constrained-platforms]] cojson tutorial: [[http://hutorny.in.ua/projects/cojson-tutorial]] Library sources: [[https:/github.com/hutorny/cojson]] mbed example: [[https://raw.githubusercontent.com/hutorny/cojson/master/examples/json_via_mbed_stream.cpp]] Status on mbed platform: buildable with arm-none-eabi-g++ <<code title=Example of using cojson>> #include "cojson.hpp" using namespace cojson; #define NAME(s) static inline constexpr const char* s() noexcept { return #s; } class Pdo { struct Name { NAME(u) NAME(s) NAME(v) }; char s[16]; short u; short v; // JSON structure definition static const clas<Pdo>& structure() { return O<Pdo, P<Pdo, Name::s, countof(&Pdo::s), &Pdo::s>, P<Pdo, Name::u, decltype(Pdo::u), &Pdo::u>, P<Pdo, Name::v, decltype(Pdo::v), &Pdo::v> >(); } public: // reading JSON inline bool read(lexer& in) { return structure().read(*this,in); } // writing JSON inline bool write(ostream& out) { return structure().write(*this,out); } }; <</code>>
