Thoughts on Metaclasses - Herb Sutter - Keynote [ACCU 2017]

Post

  • Depends on:
    • C++17
    • concepts (C++20)
    • constexpr, if constexpr
    • compile-time meta-programming (P0589, P0633)
    • reflection (P0194, P0385, P0578, P0590, P0598)
  • Start watching at 18m

Reflection

1$T, $expr

Compile-time programming

1constexpr {
2    for (auto m: $T.variables())
3        if (m.name() == "xyzzy")
4            -> { int plugh; }
5}

Pystring is a collection of C++ functions which match the interface and behavior of python’s string class methods using std::string. Implemented in C++, it does not require or make use of a python interpreter. It provides convenience and familiarity for common string operations not included in the standard C++ library. It’s also useful in environments where both C++ and python are used.

Overlapping functionality (such as index and slice/substr) of std::string is included to match python interfaces.

Modern C++ Design reloaded - Odin Holmes [ACCU 2017]

  • This is an “update” to the book “Modern C++ Design” by Andrei Alexandrescu
  • Discusses updated template metaprogramming techniques:
    • policy-based class design;
    • replacing multiple templates with variadic templates.

“Concept”-based polymorphism
