Jungles CPP utilities

This repo contains C++ utilities that help me develop code faster, by wrapping common entities into those reusable classes.

C++17 is required.

Explore test directory to find out how to use the utilities.

jungles::assign_callback

Allows to assign a lambda function to a plain C pointer, e.g.:

static unsigned (*plain_c_pointer)(char, float);

plain_c_pointer = jungles::assign_callback([](char, float) -> unsigned { return 5; });

auto r{(*plain_c_pointer)('c', 32.2)};

std::cout << r << std::endl; // Prints '5'

jungles::overload

It is taken from the Bartłomiej Filipek's blog: Variant and Overload

Algorithms

Defined in jungles/algorithm.hpp.

jungles::copy

Is the same as std::copy, but the iterators may have different types, e.g. the end iterator can be a sentinel.

jungles::calculate_correlation_function

Calculates correlation function for num_offsets of the signal, with reference to pattern. Uses Pearson correlation coefficient formula for each offset.

jungles::singleton

CRTP utility to be used by class if one wants to indicate that the class is a Singleton - only one instance at a time can be running:

class USBDriver : public jungles::Singleton<USBDriver>
{
    // ...
};

{
    USBDriver{};
    USBDriver{}; // Will throw 
}

{

    {
        USBDriver{};
    }

    {
        USBDriver{}; // OK
    }
}
