stl_ext

API inspired by C++11 standard library

<range.hpp>

This header contains utilities for range-based for loops. For example:

std::vector<std::string> poem { "Marry", "had", "a", "little", "lamb" };
for (auto && s : reverse(poem))
    std::cout << s << " "; // lamb little a had Marry
std::cout << std::endl;

for (auto && s : std_ext::slice(poem, 2))
    std::cout << s << " "; // a little lamb
std::cout << std::endl;

make_range(begin, end)

Synopsis:

template <typename It>
    auto std_ext::make_range(It begin, It end);
template <typename It>
    auto std_ext::range(It begin, It end);

Creates an object usable in a range-based for loop, iterating between begin and end. range and make_range are aliases for the same functionality, with the latter name similar to the std::make_* family, such as std::make_pair or std::make_shared.

reverse(container)

Synopsis:

template <typename Container>
    auto std_ext::reverse(Container& container);
template <typename Container>
    auto std_ext::reverse(const Container& container);

Creates an object usable in a range-based for loop, iterating between container.rbegin() and container.rend().

reverse(array)

Synopsis:

template <typename T, size_t len>
    auto std_ext::reverse(T (&array)[len]);

Iterates over the elements of the table in reverse order.

slice(container, begin, end)

Synopsis:

template <typename Container>
    auto std_ext::slice(Container& container, size_t begin, size_t end);
template <typename Container>
    auto std_ext::slice(const Container& container, size_t begin, size_t end);
template <typename T, size_t len>
    auto std_ext::slice(T (&container)[len], size_t begin, size_t end);

Alias for make_range(begin(container) + begin, begin(container) + end).

slice(container, begin)

Synopsis:

template <typename Container>
    auto std_ext::slice(Container& container, size_t begin);
template <typename Container>
    auto std_ext::slice(const Container& container, size_t begin);
template <typename T, size_t len>
    auto std_ext::slice(T (&container)[len], size_t begin);

Alias for make_range(begin(container) + begin, end(container)).
