Re: Safe sdl2 wrapper library?

[wizzardx]

Thanks for the idea though.

I'm going through lazyfoo tuts, and making a high level but also really safe 
wrapper while I'm about it.

The high level wrapper builds on top of the really safe low level wrapper I was 
working on before.

So eg, my lazyfoo chapter 01 port looks like this:
    
    
    import ../../my_sdl2_libs/high_level_sdl2
    
    const
      SCREEN_WIDTH = 640
      SCREEN_HEIGHT = 480
      WHITE = (0xFF, 0xFF, 0xFF)
    
    proc main =
      var sdl2_context = initSdl2Context(initvideo=true)
      
      var window = sdl2_context.createWindow(title="SDL Tutorial",
                                             width=SCREEN_WIDTH,
                                             height=SCREEN_HEIGHT,
                                             windowShown=true)
      var screenSurface = window.getSurface()
      screenSurface.fillRect(color=WHITE)
      window.updateSurface()
      sdl2Context.delay(2.0)
    
    main()
    

There's no pointers or references used there, all of those are wrapper objects 
with built-in Nim destructors, so they also automatically tidy their resources 
when they go out of scope.

Also not using OR-based flags, but rather bool arguments.

Nim's named and optional arguments are really awesome, you don't need to use 
builder patterns nearly as much as in some other langs.
