-The beginnings of modular design for SDL Perl

-<div style="text-align: right;"><i>“Do or do not... there is no try.”</i><br /></div><div style="text-align: right;"><i>--yoda </i><br /><br /></div><h1>The design before</h1><br />The bindings before were all in <a href="http://github.com/kthakore/SDL_perl/blob/master/src/SDL.xs">one huge XS file</a>. 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. <br /><br /><h1>The design we are aiming for</h1>Simple <a href="http://github.com/kthakore/SDL_perl/blob/master/src/Rect.xs">one XS</a> per Module. This would also simplify the Build code.<br /><br /><h2>First Step </h2><br />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 <a href="http://github.com/kthakore/SDL_perl/blob/master/src/Rect.xs#L16">is in XS</a> we have only unnamed parameters. <br /><br /><br /><h3>Before</h3><br />SDL::Rect->new( -x => 0, -y => 0, -width => 0, -height => 0);<br /><br /><h3>After</h3><br />SDL::Rect->new(0, 0, 0, 0);<br /><br />Ideally we would like both ways of constructing Rect.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3102167581424744259-6151839795039915111?l=yapgh.blogspot.com' alt='' /></div></div></div>

+SDL Perl 2.511 is showing great promises. The initial tests show a great deal of stability. <a href="http://search.cpan.org/~kthakore/SDL-2.511/">http://search.cpan.org/~kthakore/SDL-2.511/</a><br />
+<br />
+ Moreover we are seeing more varied users of SDL Perl.<br />
