iod

Given that the whole framework is in roughly 31kloc of C++ written mostly by you and this not your first framework. Can you talk more about your design choices, what the architectural patterns are and how metaprogramming plays a role [1] ? Besides your experience from writing Silicon [2], what other frameworks do you like the design of? What C++ codebases do you like or find interesting from a design perspective?

The problem with deconstructing a tuple is that you can easily make mistake about the order of its members. The struct is a much better solution to me, and you can go over the problem of the weirdly named one-off struct by using the iod library (https://github.com/matt-42/iod): foo() { return D(_id = "test", _age = "42" }; } auto r = foo(); std::cout << r.id << r.age << std::endl;

It is not part of C++14, it is a small syntaxic sugar that compiles to iod symbols. A compiler convert it to plain C++. In short, their are empty objects holding a unique C++ type. More info here: https://github.com/matt-42/iod

The source code is here, interesting if you enjoy c++14 meta programming: https://github.com/matt-42/iod/blob/master/iod/di.hh

The introspection comes from the SIO's of the iod library, they are novel types of object offering introspection at compile time. The iod library makes iterating on the members of an sio object trivial with the foreach primitive (see https://github.com/matt-42/iod/blob/master/iod/json.hh#L417) so generating a serializer / deserializer like this one is not so complicated since you have access to the type and the name of each members. For more info, check the readme of https://github.com/matt-42/iod I did my best to explain the concepts of the library. But I'm still lacking of time to polish the documentation....

This is thanks to the C++11 variadic templates that symplifies (a lot) the writting of such abstractions. The object model is only 100 lines of C++11: https://github.com/matt-42/iod/blob/master/iod.hh
