SDLAda

This is a new variable thickness Ada 2012 binding to SDL 2.x.y (http://www.libsdl.org). This means that things are wrapped when they need to be into a thicker binding and those things that can just be imported, are.

There will still be a need to use conditional compilation for the various platforms as there will be some platform specifics which cannot be abstracted out leanly, but this will be reduced as much as possible.

The bindings are only generated for the specific parts of SDL which Ada does not already have support for, i.e. threads are not bound as Ada has tasking support built in.

Usage, Licence & Attribution

SDLAda is distributed under the same zlib licence as the SDL libary is. You may use this library as in any way you like whether free or commercial. I would add that whilst you don't have to state that your game uses this library, I would it would be nice if you did, it's all good advertising for Ada :)

You do not need to complete any copyright assignment forms, the licence will not change from zlib as I want people to be able to use the library however they wish without restrictions.

Building

There are a number of variables which can be set to control the compilation:

SDL_PLATFORM = Can be set to one of the following values: linux, windows, macosx, ios or android SDL_MODE = Can be one of: debug or release. Defaults to debug.

cd build/gnat
make SDL_PLATFORM=linux SDL_MODE=release

Installation

make SDL_PLATFORM=linux SDL_MODE=release DESTDIR=/myprefix install

Thanks to

Michael B for providing an initial implementation of RWops.

WARNING!!!

I have tried to model the types correctly, but remember SDL is a C library and some things may not make sense. Please file a bug report if you use this library and find that a type does not cover enough values for cross-platform use.

TODO

Anything listed here is a question of whether it's required.

  • Do we need to hook into the Assert module? To raise an exception maybe?
  • Create event tagged type hierarchy, use Poll to convert the C events into these types.
  • Task safe event handling?
  • Split Image, TTF into separate GPR files.
  • Cross platform testing.
  • Optimisations to make the library as thin as possible:
    • Enable -gnatN for inlining.
    • Try to get as much pre-elaborated as possible.
  • Disable a shared library build, make it a static only build, this makes it easier to distribute. i.e. Link with this library and distribute SDL2 libs only.
  • Hide the RWops stuff maybe? Should really be using Ada streams and files.
