Adding bindings to SDL2_image

[Armael]

Hi,

I was wondering what would be the be the simplest way to bind functions from SDL2_image (which is pretty useful, and that I would like to use)?
SDL2_image is distinct from the base C library, so it would be legit to separate the OCaml bindings from tsdl; however it would be great to be able to reuse the ctypes definitions from tsdl, which are not available (obviously) in the API.

I also tried a bit to just modify tsdl.ml in place to add some bindings, but I did not manage to tweak the build system to link to SDL2_image, so here I am, asking for help :-°.

I would rather keep things separate separate and expose the definitions you need in order to interact with SDL. What would you need ?

Note that there are already a few undocumented unsafe_* functions that are available to interact with tsdl's otherwise abstract types. See @tokenrove 4a4ffc2 commit who explicitly mention SDL image.

That didn't make it into a release yet as I would like to have #13 solved first (but don't have the time to look into this right now).

Incidentally, I have some SDL_image bindings in the same style as tsdl-mixer and tsdl-ttf, but I had been waiting til I had time to polish all three (including documentation and tests) to release them. But if you are interested and don't already have your bindings written, check out https://github.com/tokenrove/tsdl-image and encourage me to Do The Right Thing and get them cleaned up and into opam.

@tokenrove if you need a release of tsdl to get them out before I manage to have a look at #13, just ping me and it will be done.

Oh, thanks for the answers! 4a4ffc2 looks great indeed, and I'll be very happy with a release of your SDL_image bindings! In the meantime I'm gonna pin the git version and try them out :).

@dbuenzli Great to know. Thanks. I will look into it this weekend.

@Armael Let me know if there are any problems, of course.
