-The beginnings of modular design for SDL Perl +A summer of possibilities (SDL_perl and GSOC 2010 )
-
The bindings before were all in one huge XS file. This was then exported into the SDL module. This means that the XS file has to handle with macros if any component (e.x SDL_Mixer) is not compiled. Moreover having ever binding in one XS file prevents use to treat C structs as object with only one point of free and malloc. This would be BEGIN and DESTROY in Perl. Also the monolithic design introduces a lot of bugs because we have to use free and malloc all over the place. Lastly SDL monolithic design has the constructor for all structs in both Perl and in XS.
We have began with SDL Rect. It is in github master branch now. We are in the progress of making it back compatible. Originally SDL::Rect took named variables as parameters for new(). Now since the constructor is in XS we have only unnamed parameters.
SDL::Rect->new( -x => 0, -y => 0, -width => 0, -height => 0);
SDL::Rect->new(0, 0, 0, 0);
Ideally we would like both ways of constructing Rect.

The design we are aiming for
Simple one XS per Module. This would also simplify the Build code.First Step
We have began with SDL Rect. It is in github master branch now. We are in the progress of making it back compatible. Originally SDL::Rect took named variables as parameters for new(). Now since the constructor is in XS we have only unnamed parameters.
Before
SDL::Rect->new( -x => 0, -y => 0, -width => 0, -height => 0);
After
SDL::Rect->new(0, 0, 0, 0);
Ideally we would like both ways of constructing Rect.
