Development Update
Monday, 02 November 2009
Tags: [Perl] [SDL] [Updates]
In the past week the SDL Perl team has been busy! This is what we have accomplished
Commitment to Testing! In an effort to focus on continuing our focus on testing we have setup a Smolder site for the SDL redesign process. Currently we have two platforms (linux, windows32) regularly tested on here. If there are more people following the redesign process and would like to share their test results; contact us at sdl-devel@perl.org and we will provide access to you.
SDL::Video For the core development most of the focus has been on redesigning around the Video category of the SDL perl API. As of now we are 50% done . 19 functions out of 38 functions have been implemented and tested.

The beginnings of modular design for SDL Perl
Sunday, 11 October 2009
Tags: [Design] [SDL] [Updates]
The design before
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.
The design we are aiming for Simple one XS per Module. This would also simplify the Build code.

Design of SDL::Rect
Saturday, 12 September 2009
Tags: [Design] [Perl] [SDL]
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.

Using the awesome perlobject.map as a reference I was able to create a blessed perl object in XS . So now SDL::Rect->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.

Why I will be sticking to CPAN
Sunday, 06 September 2009
Tags: [CPAN] [Perl] [SDL]
Recently there was really long discussion on sdl-devel@perl.org about providing packages for SDL perl rather than focusing on CPAN releases. The gists of the argument was that SDL perl should be making platform specific packages for end users. I agree with this idea but I do have to face the truth.
The truth is there are very few developers currently working on SDL Perl. The truth is CPAN provides several tools that which currently drives development for SDL Perl. There are people interested in packaging SDL Perl ( kmx , jean and Jerome Quelin). The truth is there are other very critical areas we can focus on.
If there are people looking to package SDL Perl for their platform please contact us at sdl-devel@perl.org.

This is a reply to szabgab's post on how to get newbies interested in Perl modules. Being a newbie in Perl myself I thought I should take a shot.
I was thinking you can make projects more accessible to newbies by having a step by step plan included with where they need to look. For example for docs of SDL_perl:
Look at SDL docs [ link ] See where SDL_perl is using the same functions [ link ] and the docs to this file [ link ] Use the pod format to add it to the source [ link to using pod ] {BONUS} Come up with tutorial or cookbook [ link to example ] Submit code to github [ link ] or email them to me [ link ]

Updates on Plan for v2.4
Monday, 31 August 2009
Tags: [Perl] [SDL] [Updates]
After some hunting for memory leaks, it became obvious that some rewrite of XS will be necessary. Since this will be a big undertaking I asked for some help from chromatic and garu . We came up with the following plan for v2.4.
Currently all XS is mapped to the SDL_perl module. This does not reflect the modular nature of the sdl libs. So the plan is to gradually move SDL structs and their respective functions to their correct namespaces. We will start with SDL::Rect as garu has added many tests for it. This way the build system will be a lot easier to hack since Module::Build was made for one XS per module. Moreover we will move the Build utilities to Alien::SDL, making it even simpler. The main idea is to adhere to single responsibility principle and encapsulation.
Obviously this will take some time and effort, but it will pay off in the long run. Any help will be greatly appreciated.

Catching memory leaks in XS
Friday, 28 August 2009
Tags: [Perl] [SDL]
So I am trying to find and plug memory leaks in SDL perl. Most of the memory leaks occur because in XS a reference is still held. One very expensive mem leak was caught by TELS really early on here . The problem occurs where in XS there is

Hi Folks
This past week I have been working on making interfacing physics with SDL rendering a lot easier.

Using this idea I have completed a preliminary work for SDLx::Controller::Object. The demo below shows an example that was made with it. The SDLx* code is available at http://github.com/kthakore/SDL_perl and demo code is available at http://github.com/kthakore/scroller .

This was a project to test how well Perl+SDL performs and does not use OpenGL at all. This is all perl and SDL, with the help of libsdl_gfx for SDL::GFX::Primitives. Texture mapping doesn't use SDL::GFX::Primitives because textured_polygon just takes a surface, tiles it, and clips out the polygon, which doesn't look 3D at all.

SDL 2.503 Released!
Thursday, 22 July 2010
Tags: [Perl] [Releases] [SDL]
SDL 2.503 has been released on to CPAN. The changes are mostly in the new features added to SDLx::* layer. However as our continuing attempt to improve cross platform support we have some low level fixes.
Most interstingly we have begun work on SDLx::Sprite::Animated. Although, volatile, this addition will be highly anticipated. We look forward for more work on it soon. Additionally are the changes in SDLx::Surface. SDLx::Surface is an attempt to provide gfx, pixels, video and low level surface functions in a combined and simpler interface.
Since SDLx::Sprite and SDLx::App depends on SDLx::Surface, new features will be propagated and the magic amplified! These are exciting times for SDL in Perl. So come join us for great justice on #sdl irc.perl.org or sdl-devel@perl.org .

Hello folks,
Recently we have been working on making the Perl syntax sugar for SDL in the form of SDLx. So far we have got the SDLx::Surface and SDLx::Sprite (garu++) done. So the first thing we did was throw together a quick Zelda map walker. As you can see above.  The code is at  http://gist.github.com/478440 . The SDL code that this depends on will be SDL 2.503 soonish . We are in the process of cleaning up some more SDLx and Alien::SDL bugs. After that SDLx::App will be overhauled to make this sort of thing even easier. Finally living up to our goal of  'Simple Games Easy. Complex Games Possible.' 
UPDATE: with some help, and newcomer jtpalmer's help we have added Link

The Build Process of SDL Perl
Wednesday, 07 July 2010
Tags: [Building] [Perl] [SDL]
A while ago I had a long chat with mst on why SDL uses Module::Build rather then Make. I told him it is a simple matter of code inertia. The existing Module::Build system has worked well for us so far. Never the less, he convinced me that switching to Make will improve debugging the Build system. But to be able to switch we will need to completely replace the Build system. I am not prepared to do that so I will just present the requirements so mst or someone else can at least attempt to switch.

Getting people to use SDL Perl: Docs, API, and Distribution
Friday, 07 May 2010
Tags: [API] [Design] [Docs] [Perl] [SDL]
The road so far
Things have been busy but fruitful. Our two core modules are getting to be a bit more stable. Alien::SDL 1.405 is behaving well. This foundational stability will start to show results in SDL too I believe. Most excitingly the main developer of frozen-bubble is reviewing our Games::FrozenBubble port to CPAN. All good and well, but to keep this project going we need to improve.
Getting people to use SDL Perl
After a long chat with a new SDL user on #sdl today, I realize we still have some way to go. Currently it seems we are lacking in a few areas. We can definitely use some feedback and help in these areas.
Tutorials/Documentation

We have more docs now on http://sdl.perl.org but they suck
What type of tutorials do you think will be good for beginners?
A project start to finish?
Individual tutorials for various topics?
What needs to go in SDL::CookBook?

API sweetness
SDL Perl depends on distinct C libraries
This makes naming conventions, data formats different the SDL:: namespaces
How do people design this stuff?
We are hackers and we just go do stuff but I think this needs some prior thought
Any takers?

Distribution
If SDL scripts can be packaged up simply for game developers to distribute their games it will be a big plus
One way is a Wx::Perl::Packer clone
Another is a CPAN/Steam clone that game devs can upload games too and people can point and click download games? 
If anyone wants to help in these areas please talk to us on sdl-devel@perl.org.
