C++14 Data Framework

What is this data framework ?

In C++, you often need to create a data layer that supports introspection, serialization. I decided to factorize this layer in one library, which use the new C++14 standard to support interesting features:

• access by name while still type-safe
• introspection
• JSON serialization, easily extendable to other formats

Planned features

• Data migration support (versionning, update, ...)
• More serialization formats

Supported platforms

• Mac OS X - Clang 3.5+
• Linux - Clang 3.5+
• Linux - G++ 4.9+
• Windows - MSYS2 MINGW 4.9+
• Windows - MSVC 2015 to be tested

UNIX Build

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make && ctest

Declare a new data type

#include <data.h>

struct Todo
{
  #define TodoFields(F) \
    F(title,       std::string,  "TODO") \
    F(priority,    int,          -1) \
    F(description, std::string,  ) \

  DATA_IMPL(TodoFields)
};

Serialization support

#include <data.h>
#include <datajson.h>

std::string encodeATodo(const Todo & todo) {
  JsonVal js;
  const std::string todoSerialized = todo.encode(js);
  return todoSerialized;
}

void decodeATodo(Todo & todo, const std::string & todoSerialized) {
  Json::Reader rdr; JsonVal js; // JSON encoder related
  rdr.parse(todoSerialized, js);
  todo.decodeStrict(js);
}
