uTempl - Modern C++ Template Library

Features

Ranges Like Interface For TupleLike

#include <utempl/utils.hpp>

auto main() -> int {
  using namespace utempl;
  constexpr TupleLike auto tuple = Tuple{1, 2, 3, 4, 5, 6}
    | Take<5>()
    | Map([](int arg){return arg + 1;})
    | Map([](int arg) -> float {return arg;})
    | Reverse()
    | Take<3>(); // Lazy evaluate
  static_assert(tuple == Tuple{6.0f, 5.0f, 4.0f});
};

Storage types in array

#include <utempl/meta_info.hpp>
#include <array>
#include <type_traits>

auto main() -> int {
  using namespace utempl;
  constexpr std::array types{kTypeId<int>, kTypeId<void>};
  static_assert(std::is_same_v<GetMetaInfo<types[0]>::Type, int>);
  static_assert(std::is_same_v<GetMetaInfo<types[1]>::Type, void>);
  static_assert(std::is_same_v<decltype(GetTypeListForTag()), TypeList<int, void>>);
};
