C++ wrapper for SDL2

sdl2pp

(Work in Progress) C++ wrapper for SDL2.

Example

#define SDL2PP_USE_IMAGE
#include <experimental/optional>
#include "sdl2pp.h"

using namespace sdl2pp;
using namespace std::experimental;

int main() {
    try {
        /* RAII-based library initialization / finalization; So as  */
        Init init(SDL_INIT_VIDEO);
        InitImage initImage(IMG_INIT_PNG);
        
        /* Create SDL objects via constructors */
        Window window("SDL2PP", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
                400, 300, SDL_WINDOW_SHOWN);
        Renderer renderer(window, -1, SDL_RENDERER_ACCELERATED);
        Texture texture(renderer, "assets/background.png");
        
        bool quit = false;
        
        EventDispatcher e;
        
        /* Handle events with lambda expressions */
        e.quit = [&quit](const SQL_QuitEvent &event) {
            quit = true;
        };
        
        while (!quit) {
            while (e.poll()) {}
            
            renderer.setDrawColor(0xff, 0x80, 0x80, 0xff);
            
            /* Overloaded member functions are provided */
            renderer.fill(); // Overloading fillRect()
            
            /* Replace nullable pointers with std::optional's */
            renderer.copy(texture, nullopt, nullopt);
            renderer.present();
        }
        /* Exception handling instead of error code checking */
    } catch (const Exception &e) {
        SDL_Log("%s\n", e.what());
    }
    
    return 0;
}

Feature

Currently supported wrappers are the following

• SDL
  • Library initialization / finalization
  • Graphics
    • SDL_Window
    • SDL_Surface
    • SDL_Renderer
    • SDL_Texture
  • Lambda expression based event handling
• SDL_image
  • Library initialization / finalization

If you want to use SDL2_image features, define SDL2PP_USE_IMAGE macro in compiler options.
