VisualCamp Common C++ library

Features

• algorithm library implemented in C++14 (up to C++23 standard)
• concepts library implemented in C++14 (up to C++23 standard)
• ranges library implemented in C++14 (up to C++26 standard)
• utility library implemented in c++14 (up to C++26 standard)
  • expected
  • optional
  • span
  • variant
• Other ~ C++26 libraries

All features are compatible with existing STL

Examples

// All features available in C++14

#include "vccc/ranges.hpp"

// Deduced as std::vector<int>
auto v = vccc::views::iota(10)
       | vccc::views::take(4)
       | vccc::ranges::to<std::vector>();

std::pair<int, std::string> parr[] = {{1: "one"}, {2: "two"}};

// Deduced as std::map<int, std::string>
auto m = vccc::ranges::to<std::map>(parr); 

// Deduced to std::vector<std::pair<int, std::string>>
auto pv = vccc::ranges::to<std::vector>(parr);


auto arr = {'A', 'B', 'C', 'D'};
auto m = v | vccc::views::enumerate | vccc::ranges::to<std::map>();

#if __cplusplus < 201703L
    for (const auto kv : m)
      std::cout << '[' << std::get<0>(kv) << "]:" << std::get<1>(kv) << ' ';
#else
    for (auto const [key, value] : m)
      std::cout << '[' << key << "]:" << value << ' ';
#endif
