Small modification for even terser error handling:
T sdlEnforce(T)(T result, string message = null)
{
if (!result)
throw new SdlException("SDL error: "
~ (message ? message ~ ": " : "")
~ to!string(SDL_GetError()));
return result;
}
Usage:
gWindow = SDL_CreateWindow(...).sdlEnforce("SDL_CreateWindow");
class SDLError : Error {
This is misuse of the Error class. Don't do this, subclass Exception
instead. D errors should be used to indicate logic errors (conditions
that can only arise from a bug in the program), not failures in
3rd-party libraries.
I use Exception for recoverable errors and Error for those that aren't.
