Module::Build::SDL(3) Module::Build subclass for building SDL apps/games [not stable yet]

SYNOPSIS

When creating a new SDL application/game you can create Build.PL like this:


use Module::Build::SDL;

my $builder = Module::Build::SDL->new(
module_name => 'Games::Demo',
dist_version => '1.00',
dist_abstract => 'Demo game based on Module::Build::SDL',
dist_author => '[email protected]',
license => 'perl',
requires => {
'SDL' => 0,
},
#+ others Module::Build options
)->create_build_script();

Once you have created a SDL application/game via Module::Build::SDL as described above you can use some extra build targets/actions:

  • you can create a PAR distribution like: 

     $ perl ./Build.PL
 $ ./Build
 $ ./Build par

    There are some extra parameters related to 'par' action you can pass to Module::Build::SDL->new(): 

     parinput  => 'bin/scriptname.pl'
 paroutput => 'filename.par.exe',
 parlibs   => [ qw/SDL SDL_main SDL_gfx/ ],  #external libraries (.so/.dll) to be included into PAR
 parmods   => [ qw/Module::A Module::B/ ],   #extra modules to be included into PAR
  • to run the game from distribution directory you can use: 

     $ perl ./Build.PL
 $ ./Build
 $ ./Build run
  • TODO: maybe some additional actions: parexe, parmsi, deb, rpm

DESCRIPTION

Module::Build::SDL is a subclass of Module::Build created to make easy some tasks specific to SDL applications - e.g. packaging SDL application/game into PAR archive.

APPLICATION/GAME LAYOUT

Module::Build::SDL expects the following layout in project directory: 

 #example: game with the main *.pl script + data files + modules (*.pm)
 Build.PL
 lib/
     Games/
           Demo.pm
 bin/
     game-script.pl
 data/
     whatever_data_files_you_need.jpg

the most simple game should look like: 

 #example: simple one-script apllication/game
 Build.PL
 bin/
    game-script.pl

In short - there are 3 expected subdirectories:

  • bin - one or more perl scripts (*.pl) to start the actual application/game
  • lib - application/game specific modules (*.pm) organized in dir structure in ``usual perl manners''
  • data - directory for storing application data (pictures, sounds etc.). This subdirectory is handled as a ``ShareDir'' (see File::ShareDir for more details)
  • As the project is (or could be) composed as a standard perl distribution it also support standard subdirectory 't' (with tests).

RULES TO FOLLOW

When creating a SDL application/game based on Module::Build::SDL it is recommended to follow these rules:
  • Use the name for your game from Games::* namespace; it will make the later release to CPAN much easier.
  • Put all data files into data subdirectory and access the data subdir only via File::ShareDir (namely by calling distdir() function)
  • TODO: maybe add more
