908 :: Converting C struct with reserved words

• jgoodgive (orginal) [2015-02-20T23:07:43+01:00] view original

  I am manually wrapping a haptic lib for sdl2 and run into this struct:

  typedef struct SDL_HapticDirection
  {
      Uint8 type;
      Sint32 dir[3];
  } SDL_HapticDirection;
  Run

  I guess sdl really wants it to be named type. Is there a simple solution?

  (manually wrapping since I cannot get c2nim to install using nimble, since nimble doesnt recognize my nim installation)

  Generally we call it typ in this case.

  I have decided to use backticks like `type` always. So it is consistent and easier to guess for users.

  Latest c2nim is smart, it is called 0.9.7, and uses `func`, `object` . Guess it will generate `type`, but I am not sure.

  Edit:

  You may manually install c2nim, I did that once. But nimble install should work, and c2nim is nice.

  typ it is

  What do you call "end" in a struct?

  Thank you!

  I usually change "type" to "kind".

  Also, you might want to look at my sdl2 wrapper for nim: https://github.com/Vladar4/sdl2-nim

  @Vladar Have you a few days ago converted all the sdl2 header files? Do you know that theres already a project, doing that, that people are using?

  If yours is "complete" and you have tested it then why not merge the two? EDIT: @Vladar. Is this a case of things happening in 2 places at the same time or am I missing something? Your code looks nice and you have a nice game engine testing it.

  Edit: @Vladar It seems that all the wrappers are missing imports. E.g. joystick needs sdl_libname and gamecontroller needs rwops. They are included in the sdl wrapper but that doesnt seem to make them visible to other imports. Or am I just doing it wrong?

  Just FYI, the Urhonimo wrapper of Urho3D may be interesting. Urho3D uses SDL2.

  jgoodgive: Your code looks nice and you have a nice game engine testing it.

  Thanks, I tried to preserve all documentation from sdl2 headers and correctly convert it to nim's documentation comments. If by game engine you mean nimgame, it isn't based on sdl2-nim yet, but this is planned for the future and also might help debugging sdl2-nim itself.

  You supposed to import sdl2/sdl as it includes all headers except sdl_image, sdl_mixer, sdl_net, sdl_ttf and sdl_gfx*, which you import when needed.
