## About

This library was developed to combat insecure methods of storing random data into modern C++ containers. For example, old and clunky PRNGs. Thus, rrgen uses STL’s distribution engines in order to efficiently and safely store a random number distribution into a given C++ container.

## Installation

1. `git clone https://github.com/josh0xA/rrgen.git`

2. `cd rrgen`

3. `make`

4. Add `include/rrgen.hpp` to your project tree for access to the library classes and functions.

## Official Documentation

_rrgen/docs/index.rst_

## Supported Containers

1. `std::vector<>`

2. `std::list<>`

3. `std::array<>`

4. `std::stack<>`

## Example Usages

```auto
#include "../include/rrgen.hpp"
#include <iostream>

int main(void)
{
    // Example usage for rrgen vector
    rrgen::rrand<float, std::vector, 10> rrvec;
    rrvec.gen_rrvector(false, true, 0, 10);
    for (auto &i : rrvec.contents())
    {
        std::cout << i << " ";
    } // ^ the same as rrvec.show_contents()

    // Example usage for rrgen list (frontside insertion)
    rrgen::rrand<int, std::list, 10> rrlist;
    rrlist.gen_rrlist(false, true, "fside", 5, 25);
    std::cout << '\n'; rrlist.show_contents();
    std::cout << "Size: " << rrlist.contents().size() << '\n';

    // Example usage for rrgen array
    rrgen::rrand_array<int, 5> rrarr;
    rrarr.gen_rrarray(false, true, 5, 35);
    for (auto &i : rrarr.contents())
    {
        std::cout << i << " ";
    } // ^ the same as rrarr.show_contents()

    // Example usage for rrgen stack 
    rrgen::rrand_stack<float, 10> rrstack;
    rrstack.gen_rrstack(false, true, 200, 1000);
    for (auto m = rrstack.xsize(); m > 0; m--)
    {
        std::cout << rrstack.grab_top() << " ";
        rrstack.pop_off();
        if (m == 1) { std::cout << '\n'; }
    } 
}
