Lately we have been working on cleaning up the XS name spaces of SDL perl. After some bumps and falls we came up with a separated Rect module. Rect is one of the most simple C struct as shown below. <br />

Using the awesome <a href="http://cpansearch.perl.org/src/DMR/CookBookB-19960430/perlobject.map">perlobject.map</a> as a reference I was able to create a <a href="http://github.com/kthakore/SDL_perl/blob/a1b835c168ec184abc01edbc01862ffa15624c26/lib/SDL/Rect.pm">blessed perl</a> object in <a href="http://github.com/kthakore/SDL_perl/blob/a1b835c168ec184abc01edbc01862ffa15624c26/src/Rect.xs">XS</a>. So now SDL::Rect-&gt;new(...) gave us a blessed reference ready to go. And as an icing it would destroy itself properly no matter where it was used. But once I brought it into our existing code base, garu pointed out the extending it was a little bit of a mess. So far to extend Rect we have to something like below. Any comment or advice would be much appreciated.<br />

Have at it I am a big boy. You can grab the code like this.<br />
Only If you don't already have a local git repo:<br />
<br />
<blockquote>mkdir SDL<br />
cd SDL<br />
git init .</blockquote><br />
Then do this or skip to this if you already have a local git repo<br />
<blockquote>git pull git://github.com/kthakore/SDL_perl.git experimental</blockquote><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3102167581424744259-3340771783563950133?l=yapgh.blogspot.com' alt='' /></div>
