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.

Providing direct memory access to SDL_Surface's pixels
Wednesday, 23 June 2010
Tags: [Pack] [Perl] [SDL] [Surface] [XS]
In an attempt to make pixel access easier on SDL_Surface pixels. I have started work on SDLx::Surface . So far I have only start on the 32 bpp surfaces.
The general idea is to make Pointer Values (PV) of each pixel in the surface and place them into a 2D matrix. First I make pointer values like this:
SV * get_pixel32 ( SDL_Surface * surface , int x , int y )

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.

Perl+SDL 3D Rendering

Recently we have done a lot of work on the next release of SDL Perl. But it all pays off when I see users do cool things as one of the users has done below. Talon^++! This project is a great example for people wanting to learn 3D from scratch.

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 +Perl+SDL 3D Rendering

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.

+Recently we have done a lot of work on the next release of SDL Perl. But it all pays off when I see users do cool things as one of the users has done below. Talon^++! This project is a great example for people wanting to learn 3D from scratch.

The Build Process


- Alien::SDL
+--yapgh

-

SDL Perl depends on a few C libraries for a complete install. This is handled by Alien::SDL. First we look for existing SDL libraries and dependencies by doing a File::Find for headers. If these headers are found we present and option for the user to use those. We then store these locations in Alien::SDL->config options 'cflags', 'prefix' and 'libs'. If we do not have libraries available even for a minimum SDL installed ( SDL.h is not found). We provide several platform specific options.


-

For windows we have a simpler process. We download prebuilt binaries ( and checksum ) based on the user's selection and just copy them in to the right location. Again the 'prefix', 'cflags', and 'libs' is saved in Alien::SDL->config.


-

For *nix/MacOSX we download sources and attempt to compile them. To be able to do this we download several other dependencies like libpng, jpeg and pango. You can see how we do this using hashes here. During the compile process we also apply patches as needed for the sources. Once this is done we can head to SDL Build.PL


- SDL Perl dependency resolution
+
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's Build is responsible for linking the right libraries to the correct XS. If libraries are missing it will disable the component (not put it in SDL->config).
+Below are some screen shots of this little toy in action. If you'd like to try it yourself, you can download the entire project here. You can rotate the objects with the mouse, or keyboard arrows. Also press shift to toggle shading and space to switch objects.

-

For example to build Image.xs we require libsdl, libsdl_image and lib[jpg|png|tiff]. So we would check for these headers in the prefix provided by Alien::SDL->config. If they are not provided we will disable the SDL::Image module.


-

More over the availability of each library is specified as a -DMACRO to the gcc compiler. This way we can prevent XS failures due to missing libraries using #DEFINES. Here the SDL_image macro is defined and used. The availability of the module is then available from SDL::Config->has()
+NOTE: the project is compressed in the .tgz format, if you are a windows user, you may need
+a tool like 7zip to extract the contents.

- Conclusion
-

This is a high level overview of our Build process, because frankly I hate traumatizing my brain with this again. Credits have to go to FROGGS and kmx for helping with this Build scheme. Hopefully my post have helped people at the very least appreciate the problem scope of this Build system. That said I believe a fresh written build system, with these requirements in mind, will be more then welcome.

-SDL RC 2.5 decides to play with PDL +SDL 2.503 Released!

-PDL provides great number crunching capabilities to Perl and SDL provides game-developer quality real-time bitmapping and sound.
-You can use PDL and SDL together to create real-time,
-responsive animations and simulations.
-In this section we will go through the pleasures and pitfalls of working with both powerhouse libraries. -- David Mertnes
-
-
-

Creating a SDL Surface piddle


-PDL's core type is a piddle.
-Once a piddle is provided to PDL it can go do a numerous amounts of things.
-Please see the example in 'examples/cookbook/pdl.pl' in github.
-
-

Creating a simple piddle


-First lets get the right modules.
-
-
  use PDL;
-  use SDL::Rect;
-  use SDL::Video;
-  use SDL::Surface;
-  use SDL::PixelFormat;
-

-Suppose you want a surface of size (200,400) and 32 bit (RGBA).
-
-
my ( $bytes_per_pixel, $width, $height ) = ( 4, 200, 400 );
-

-Define the $width, $height and $bytes_per_pixel. Your $bytes_per_pixel is the number of bits (in this case 32) divided by 8 bits per byte. Therefore for our 32 bpp we have 4 Bpp;
-
-
my $piddle  = zeros( byte, $bytes_per_pixel, $width, $height );
-

-Create a normal $piddle with zeros, byte format and the Bpp x width x height dimensions.
-
-
my $pointer = $piddle->get_dataref();
-

-Here is where we get the acutal data the piddle is pointing to. We will have SDL create a new surface from this function.
-
-
my $surface = SDL::Surface->new_from( $pointer, $width, $height, 32,
-        $width * $bytes_per_pixel );
-

-Using the same dimensions we create the surface using SDL::Surface->new_form(). The $width * $Bpp is the scanline (pitch) of the surface in bytes.
-
-
warn "Made surface of $width, $height and ". $surface->format->BytesPerPixel;
-   return ( $piddle, $surface );
-

-Finally make sure that the surface acutally has the correct dimensions we gave.
-
-NOTE: $surface->format->BytesPerPixel must return 1,2,3,4. !!
-
-Now you can blit and use the surface as needed; and do PDL operations as required.
-
-

Operating on the Surface safely


-To make sure SDL is in sync with the data. You must call SDL::Video::lock before doing PDL operations on the piddle.
-
-
SDL::Video::lock_surface($surface);
- 
-    $piddle ( :, 0 : rand(400), 0 : rand(200) ) .=   pdl( rand(225), rand(225), rand(255), 255 );
-

-After that you can unlock the surface to blit.
-
-
SDL::Video::unlock_surface($surface);
-

-

Errors due to BPP at blitting


-When blitting the new surface check for the return value to see if there has been a problem.
-
-
my $b = SDL::Video::blit_surface(
-        $surface,  SDL::Rect->new( 0, 0, $surface->w, $surface->h ),
-        $app, SDL::Rect->new(  ( $app->w - $surface->w ) / 2, ( $app->h - $surface->h ) / 2, $app->w, $app->h )
-       );
- 
-    die "Could not blit: " . SDL::get_error() if ( $b == -1 );
-

-If the error message is 'Blit combination not supported' that means that the BPP is incorrect or incosistent with the dimensions. After that a simple update_rect will so your new surface on the screen.

-Providing direct memory access to SDL_Surface's pixels +Huge World Maps in less then 100 lines

-

In an attempt to make pixel access easier on SDL_Surface pixels. I have started work on SDLx::Surface. So far I have only start on the 32 bpp surfaces.


-

The general idea is to make Pointer Values (PV) of each pixel in the surface and place them into a 2D matrix. First I make pointer values like this:


-
SV * get_pixel32 (SDL_Surface *surface, int x, int y)
-{
- //Convert the pixels to 32 bit 
- Uint32 *pixels = (Uint32 *)surface->pixels; 
-
- //Get the requested pixel  
- Uint32* u_ptr =  pixels + ( y * surface->w ) + x ; 
-
-        SV* sv = newSVpv("a",1); //Make a temp SV* value on the go
-        SvCUR_set(sv, sizeof(Uint32)); //Specify the new CUR length
- SvLEN_set(sv, sizeof(Uint32)); //Specify the LEN length
-        SvPV_set(sv,(char*)u_ptr); // set the actual pixel's pointer as the memory space to use
-
- return sv; //make a modifiable reference using u_ptr's place as the memory :)
-
-}
-

-

Next I loop through all the pixels and put them in a 2D array format, shown below: 

AV * construct_p_matrix ( SDL_Surface *surface )
-{

-
my $surf32_matrix = SDLx::Surface::pixel_array($screen_surface);
-   print unpack 'b*', $surf32_matrix->[0][0]; # pixel value at x = 0 and y =0
-#OUTPUT:
-# 11111111000000000000000000000000
-

-

The structure of the PV is using Devel::Peek is :


-
print Dump $surf32_matrix->[0][0];
-#OUTPUT:
-#SV = PV(0xed0dbc) at 0xeb5344
-#  REFCNT = 1
-#  FLAGS = (POK,pPOK)
-#  PV = 0x9e04ac "\0\0\377\0"
-#  CUR = 4
-#  LEN = 4
-

-

The problem is in setting the value of this pointer value. I have tried the following things with no success:


-
if ( SDL::Video::MUSTLOCK($screen_surface) ) {
-    return if ( SDL::Video::lock_surface($screen_surface) < 0 ); #required for pixel operations
-}

-#USING pack

-#substr( $surf32_matrix->[0][0], 0, 8 * 4, 0xFF000000); segfault
-substr( ${$surf32_matrix->[0][0]}, 0, 8 * 4, 0xFF000000); #no change
-#$surf32_matrix->[0][0] = $green; SEGFAULT's cannot write to memory

\ No newline at end of file +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.'

-SDLpp.pl: Packaging SDL Scripts Alpha +The Build Process of SDL Perl

-After a lot of patches and head scratching I have an alpha version of SDLpp.pl. The purpose of SDLpp.pl is to allow SDL perl developers to package their game for end users.
+

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.



-Here is the shooter.pl packaged up:
-
-
  1. win32/64
    2. -
  2. Linux 5.88
    3. -
  3. Linux 5.10
    4. -

-We are looking into testing this on a Mac Build server.
+

The Build Process


+ Alien::SDL

-Caio
-


-

\ No newline at end of file +

SDL Perl depends on a few C libraries for a complete install. This is handled by Alien::SDL. First we look for existing SDL libraries and dependencies by doing a File::Find for headers. If these headers are found we present and option for the user to use those. We then store these locations in Alien::SDL->config options 'cflags', 'prefix' and 'libs'. If we do not have libraries available even for a minimum SDL installed ( SDL.h is not found). We provide several platform specific options.


+

For windows we have a simpler process. We download prebuilt binaries ( and checksum ) based on the user's selection and just copy them in to the right location. Again the 'prefix', 'cflags', and 'libs' is saved in Alien::SDL->config.


+

For *nix/MacOSX we download sources and attempt to compile them. To be able to do this we download several other dependencies like libpng, jpeg and pango. You can see how we do this using hashes here. During the compile process we also apply patches as needed for the sources. Once this is done we can head to SDL Build.PL


+ SDL Perl dependency resolution
+
+SDL's Build is responsible for linking the right libraries to the correct XS. If libraries are missing it will disable the component (not put it in SDL->config).
+
+

For example to build Image.xs we require libsdl, libsdl_image and lib[jpg|png|tiff]. So we would check for these headers in the prefix provided by Alien::SDL->config. If they are not provided we will disable the SDL::Image module.


+

More over the availability of each library is specified as a -DMACRO to the gcc compiler. This way we can prevent XS failures due to missing libraries using #DEFINES. Here the SDL_image macro is defined and used. The availability of the module is then available from SDL::Config->has()
+
+
+ Conclusion
+

This is a high level overview of our Build process, because frankly I hate traumatizing my brain with this again. Credits have to go to FROGGS and kmx for helping with this Build scheme. Hopefully my post have helped people at the very least appreciate the problem scope of this Build system. That said I believe a fresh written build system, with these requirements in mind, will be more then welcome.

\ No newline at end of file +PDL provides great number crunching capabilities to Perl and SDL provides game-developer quality real-time bitmapping and sound.
+You can use PDL and SDL together to create real-time,
+responsive animations and simulations.
+In this section we will go through the pleasures and pitfalls of working with both powerhouse libraries. -- David Mertnes
+
+
+

Creating a SDL Surface piddle


+PDL's core type is a piddle.
+Once a piddle is provided to PDL it can go do a numerous amounts of things.
+Please see the example in 'examples/cookbook/pdl.pl' in github.
+
+

Creating a simple piddle


+First lets get the right modules.
+
+
  use PDL;
+  use SDL::Rect;
+  use SDL::Video;
+  use SDL::Surface;
+  use SDL::PixelFormat;
+

+Suppose you want a surface of size (200,400) and 32 bit (RGBA).
+
+
my ( $bytes_per_pixel, $width, $height ) = ( 4, 200, 400 );
+

+Define the $width, $height and $bytes_per_pixel. Your $bytes_per_pixel is the number of bits (in this case 32) divided by 8 bits per byte. Therefore for our 32 bpp we have 4 Bpp;
+
+
my $piddle  = zeros( byte, $bytes_per_pixel, $width, $height );
+

+Create a normal $piddle with zeros, byte format and the Bpp x width x height dimensions.
+
+
my $pointer = $piddle->get_dataref();
+

+Here is where we get the acutal data the piddle is pointing to. We will have SDL create a new surface from this function.
+
+
my $surface = SDL::Surface->new_from( $pointer, $width, $height, 32,
+        $width * $bytes_per_pixel );
+

+Using the same dimensions we create the surface using SDL::Surface->new_form(). The $width * $Bpp is the scanline (pitch) of the surface in bytes.
+
+
warn "Made surface of $width, $height and ". $surface->format->BytesPerPixel;
+   return ( $piddle, $surface );
+

+Finally make sure that the surface acutally has the correct dimensions we gave.
+
+NOTE: $surface->format->BytesPerPixel must return 1,2,3,4. !!
+
+Now you can blit and use the surface as needed; and do PDL operations as required.
+
+

Operating on the Surface safely


+To make sure SDL is in sync with the data. You must call SDL::Video::lock before doing PDL operations on the piddle.
+
+
SDL::Video::lock_surface($surface);
+ 
+    $piddle ( :, 0 : rand(400), 0 : rand(200) ) .=   pdl( rand(225), rand(225), rand(255), 255 );
+

+After that you can unlock the surface to blit.
+
+
SDL::Video::unlock_surface($surface);
+

+

Errors due to BPP at blitting


+When blitting the new surface check for the return value to see if there has been a problem.
+
+
my $b = SDL::Video::blit_surface(
+        $surface,  SDL::Rect->new( 0, 0, $surface->w, $surface->h ),
+        $app, SDL::Rect->new(  ( $app->w - $surface->w ) / 2, ( $app->h - $surface->h ) / 2, $app->w, $app->h )
+       );
+ 
+    die "Could not blit: " . SDL::get_error() if ( $b == -1 );
+

+If the error message is 'Blit combination not supported' that means that the BPP is incorrect or incosistent with the dimensions. After that a simple update_rect will so your new surface on the screen.
+

-Games::FrozenBubble: It is a start! +Providing direct memory access to SDL_Surface's pixels

-We released a playable (client) frozen bubble on CPAN. There is more work to be done but it is a great start! It currently works on Windows and Linux.
+

In an attempt to make pixel access easier on SDL_Surface pixels. I have started work on SDLx::Surface. So far I have only start on the 32 bpp surfaces.


+

The general idea is to make Pointer Values (PV) of each pixel in the surface and place them into a 2D matrix. First I make pointer values like this:


+
SV * get_pixel32 (SDL_Surface *surface, int x, int y)
+{
+ //Convert the pixels to 32 bit 
+ Uint32 *pixels = (Uint32 *)surface->pixels; 
+
+ //Get the requested pixel  
+ Uint32* u_ptr =  pixels + ( y * surface->w ) + x ; 
+
+        SV* sv = newSVpv("a",1); //Make a temp SV* value on the go
+        SvCUR_set(sv, sizeof(Uint32)); //Specify the new CUR length
+ SvLEN_set(sv, sizeof(Uint32)); //Specify the LEN length
+        SvPV_set(sv,(char*)u_ptr); // set the actual pixel's pointer as the memory space to use
+
+ return sv; //make a modifiable reference using u_ptr's place as the memory :)
+
+}
+

+

Next I loop through all the pixels and put them in a 2D array format, shown below: 

AV * construct_p_matrix ( SDL_Surface *surface )
+{
+    AV * matrix = newAV();
+     int i, j;
+     for(  i =0 ; i < surface->w; i++)
+      {
+        AV * matrix_row = newAV();
+        for( j =0 ; j < surface->h; j++)
+        {
+           av_push(matrix_row, get_pixel32(surface, i,j) );
+        }
+        av_push(matrix, newRV_noinc((SV*) matrix_row) );
+      }
+
+ return matrix;
+}
+

+

You can see the complete here.


+

In Perl I can do a get access on this pixel using:

\ No newline at end of file +
my $surf32_matrix = SDLx::Surface::pixel_array($screen_surface);
+   print unpack 'b*', $surf32_matrix->[0][0]; # pixel value at x = 0 and y =0
+#OUTPUT:
+# 11111111000000000000000000000000
+

+

The structure of the PV is using Devel::Peek is :


+
print Dump $surf32_matrix->[0][0];
+#OUTPUT:
+#SV = PV(0xed0dbc) at 0xeb5344
+#  REFCNT = 1
+#  FLAGS = (POK,pPOK)
+#  PV = 0x9e04ac "\0\0\377\0"
+#  CUR = 4
+#  LEN = 4
+

+

The problem is in setting the value of this pointer value. I have tried the following things with no success:


+
if ( SDL::Video::MUSTLOCK($screen_surface) ) {
+    return if ( SDL::Video::lock_surface($screen_surface) < 0 ); #required for pixel operations

Rome was not built,

+

kmx++ recently worked on a brand new Build system for Alien::SDL and SDL_perl. We have managed to test it in Windows and Linux environments. We would still appreciate testing on all environments. However none of us have a shiny Mac to try this on. So if you have a Mac please consider testing the following:

+
  • Download Alien::SDL 
    • + +
    • install it
      • +
    • select build by source
      • +
    +
  • Download SDL::perl

Thank you very much!

-So I was planning staying silent until an exam I had was done. But new developers on IRC (j_king, felix and ruoso) pull me back in. Which is a good thing ...

-The new callbacks capability in audiospec allow you to procedurally generate sound now. If you would like a simple example take a look at t/core_audiospec.t. However a more fun example may be ruoso++'s tecla (a game for toddlers). Myself and Garu think it is a work of art but that is only because we are toddlers.

-On a side note some tickets on RT have also received some love ( after 3 or 4 years ... but nonetheless). TonyC++ sorry for the long time in response.

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.

On the end of the spectrum, Froggs has been hard at work on the graphical design of the site. More over with mst's help we will soon be migrating to http://sdl.perl.org.

Since the last post SDL Perl has seen an increase of interest to both use and contribute to SDL Perl. Before I dig into the updates, I would like to acknowledge them.
-

Core Development

Acme (Leon Brocard): Has started to work on the Redesign Effort with me. The help is much appreciated! Enjoy your vacation.
+You need the new code from the redesign branch to use this .

-

Website and Windows Testing

FROGGS (Tobias Leich): Came in as a new user to SDL Perl. And after breaking the redesigned SDL Perl in as many ways possible he has decided to help out on the new site.

Last Legacy Release


-Ok! Now this weekend hopefully we will release our last legacy release, after this we move on! This release will focus on showing of SDL + Perl possibilities.
-

Pong + SDL::Game::Rect

garu has been working on making SDL object extensions that provide a more perly way to use and play with the SDL bindings. To demonstrate the benefits of this SDL::Tutorial::Pong is done and being polished up. SDL::Game::Rect is a peek in to the design and vision we have for SDL down the road.
-

Design

The design we have settled on for future release for SDL Perl can be broken in to two layers, SDL::* and SDL::Game::*. Previously the SDL Perl library tried to provide C bindings and provide Perl Idiomatic access. This was messy in regards to the single responsibility principle (do one thing and do it well).
-
-We have decided to separate these two focuses into the two name spaces SDL::* and SDL::Game::*. SDL::* will provide straight access to SDL's C API, nothing less and nothing more. SDL::Game::* will extend and make pretty unicorns for Perl.
-
-This design has already begin to pay of. One major benefit been in the XS readability. Moreover since structs are treated as objects, Perl manages their destruction, and deliver less memory leaks.

  • SDL::Events at 25%
    • +
  • ~1000 tests cases passing on Windows and Linux
    • +

-

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 major release maybe coming quicker than we thought. FROGGS++ for helping a lot out on this. However we need more testers!! Please contact us on #sdl and we will set you up with an account on Smolder.

-

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.

-Why and How Frozen Bubble is going to CPAN +Development Update

-
A single drop,
-
causes the ocean to swell
-

-
So 5 weeks ago, SDL Perl was broken. It had been for several years. After the last release SDL Perl works ... somewhat. The quick releases that you have seen have been work-arounds, fixes and refactoring. This is not bad for a few weeks of work but, there is a point where code smell and technical debt is too huge to fix with out redesigning. This is that point.
-

-
Since the redesigning will take time and effort it will be good to have a leg up. This leg up is Frozen Bubble 2.20. Frozen Bubble employs a lot of C and Perl hacks to cover up for SDL Perl's lacking. This will help in a sense fast forward the code status to 2008. Since Frozen Bubble is helping us out, we can go one step forward and help it out!
-

-
So Alias (Adam Kennedy) and I have started work on making Frozen Bubble CPAN accessible. Frozen Bubble is a well know game and making it cross-platform will bring lots of attention and hopefully contributions to SDL Perl.
-

-
In Alias's earlier post about this he mentioned about making a splash and some other stuff. I will talk about how and where we will be accomplishing this task.
-

-
First we will be tracking Frozen Bubble on the new SDL Perl Trac website. This site will be similar to Padre's Trac site. As a bonus for people looking to help out in SDL Perl I have separated tasks by perceived difficulty. This will help to breakdown harder task too.
-

-
For example for Frozen Bubble the two major bumps we have run into so far are:
-

-
Migrating the SDL Perl workarounds: Ticket #3
-
Making the Build System Portable: Ticket #7
-

-
The first one will be difficult as it involves XS. So I will break it down into easier tasks with specific instruction which can then hopefully be picked up by interested contributers. The second one there is sort of a forte of Adam so I will leave it up to him. This is the process I am proposing make hard tickets, break them down.
-

-
This will generate a lot of easy tickets that will hopefully be synchronized.  If you are interested in this please give me a shout on #sdl irc.perl.org or the mailing list at sdl-devel@perl.org and I will get you registered.

+A stoic stone will sit idle,
+but will some effort,
+A rolling rock will run!
+
+

+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.
+
+
+

Site Redesign + Migration

On the end of the spectrum, Froggs has been hard at work on the graphical design of the site. More over with mst's help we will soon be migrating to http://sdl.perl.org.
+
+
+
+

Documentation

Moreover this week we have seen an increase effort from magnet on the SDL docs. Kudos!
+
+
+

SWIG Experimentation

Finally Katrina has begun looking into SWIG as alternative for SDL in the future.

Getting people to use SDL Perl: Docs, API, and Distribution

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.

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.

Huge World Maps in less then 100 lines
Friday, 16 July 2010
Tags: [Example] [Perl] [SDL] [Syntax]

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

Providing direct memory access to SDL_Surface's pixels
Wednesday, 23 June 2010
Tags: [Pack] [Perl] [SDL] [Surface] [XS]
In an attempt to make pixel access easier on SDL_Surface pixels. I have started work on SDLx::Surface . So far I have only start on the 32 bpp surfaces.
The general idea is to make Pointer Values (PV) of each pixel in the surface and place them into a 2D matrix. First I make pointer values like this:
SV * get_pixel32 ( SDL_Surface * surface , int x , int y )

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.

Perl+SDL 3D Rendering
Saturday, 31 July 2010
Tags: [Perl] [SDL] [Showcase]
Recently we have done a lot of work on the next release of SDL Perl. But it all pays off when I see users do cool things as one of the users has done below. Talon^++! This project is a great example for people wanting to learn 3D from scratch.
--yapgh
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 .

Huge World Maps in less then 100 lines
Friday, 16 July 2010
Tags: [Example] [Perl] [SDL] [Syntax]

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

Perl+SDL 3D Rendering
Saturday, 31 July 2010
Tags: [Perl] [SDL] [Showcase]
Recently we have done a lot of work on the next release of SDL Perl. But it all pays off when I see users do cool things as one of the users has done below. Talon^++! This project is a great example for people wanting to learn 3D from scratch.
--yapgh
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 .

Huge World Maps in less then 100 lines
Friday, 16 July 2010
Tags: [Example] [Perl] [SDL] [Syntax]

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.

Providing direct memory access to SDL_Surface's pixels

Tags: [Pack] [Perl] [SDL] [Surface] [XS]
In an attempt to make pixel access easier on SDL_Surface pixels. I have started work on SDLx::Surface . So far I have only start on the 32 bpp surfaces.
The general idea is to make Pointer Values (PV) of each pixel in the surface and place them into a 2D matrix. First I make pointer values like this:

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.
