Perl6::Classes project contains first class classes in Perl 5.

SYNOPSIS

use Perl6::Classes;

class Composer {
submethod BUILD { print "Giving birth to a new composern" }
method compose { print "Writing some music...n" }
}

class ClassicalComposer is Composer {
method compose { print "Writing some muzak...n" }
}

class ModernComposer is Composer {
submethod BUILD($) { $.length = shift }
method compose() { print((map { int rand 10 } 1..$.length), "n") }
has $.length;
}

my $beethoven = new ClassicalComposer;
my $barber = new ModernComposer 4;
my $mahler = ModernComposer->new(400);

$beethoven->compose; # Writing some muzak...
$barber->compose # 7214
compose $mahler; # 89275869347968374698756....

Perl6::Classes allows the creation of (somewhat) Perl 6-style classes in Perl 5. The following features are currently supported:

subs, methods, and submethods
And their respective scoping rules.

Attributes
Which are available through the has keyword, and look like $.this.

Inheritance
Both single and multiple inheritance are available through the is keyword.

Signatures
Signatures on methods, subs, and submethods are supported, but just the Perl 5 kind.

Data hiding
Using the public, protected, and private traits, you can enforce (run-time) data hiding. This is not supported on attributes, which are always private.

Anonymous classes
That respect closures. You can now nest them inside methods of other classes, even other anonymous ones!

The Perl6::Classes module augments Perls syntax with a new declarator: class. It offers the advantage over Perls standard OO mechanism that it is conceptually easier to see (especially for those from a C++/Java background). It offers the disadvantage, of course, of being less versatile.

Stamits Online Poker project is a simple OpenGL poker game that can be played online with another person.

Compilation:

Make sure you have the GNU C and C++ compilers.

Get MOGUL, the Minimal OpenGL Utility Library, compile and install it (or use a compiled binary version, if there is one available). Instructions should be included.

Open `Makefile and uncomment the lines below the label `Unix configuration.

Say `make. The result should be an executable named `sopoker in the current working directory.

Class::Meta is a Perl class automation, introspection, and data validation.

SYNOPSIS

Generate a class:
package MyApp::Thingy;
use strict;
use Class::Meta;
use Class::Meta::Types::String;
use Class::Meta::Types::Numeric;

BEGIN {

# Create a Class::Meta object for this class.
my $cm = Class::Meta->new( key => thingy );

# Add a constructor.
$cm->add_constructor(
name => new,
create => 1,
);

# Add a couple of attributes with generated methods.
$cm->add_attribute(
name => uuid,
authz => Class::Meta::READ,
type => string,
required => 1,
default => sub { Data::UUID->new->create_str },
);
$cm->add_attribute(
name => name,
is => string,
required => 1,
default => undef,
);
$cm->add_attribute(
name => age,
is => integer,
default => undef,
);

# Add a custom method.
$cm->add_method(
name => chk_pass,
view => Class::Meta::PUBLIC,
);
$cm->build;
}
Then use the class:
use MyApp::Thingy;

my $thingy = MyApp::Thingy->new;
print "ID: ", $thingy->id, $/;
$thingy->name(Larry);
print "Name: ", $thingy->name, $/;
$thingy->age(42);
print "Age: ", $thingy->age, $/;
Or make use of the introspection API:
use MyApp::Thingy;

my $class = MyApp::Thingy->my_class;
my $thingy;

print "Examining object of class ", $class->package, $/;

print "nConstructors:n";
for my $ctor ($class->constructors) {
print " o ", $ctor->name, $/;
$thingy = $ctor->call($class->package);
}

print "nAttributes:n";
for my $attr ($class->attributes) {
print " o ", $attr->name, " => ", $attr->get($thingy), $/;
if ($attr->authz >= Class::Meta::SET && $attr->type eq string) {
$attr->get($thingy, hey there!);
print " Changed to: ", $attr->get($thingy), $/;
}
}

print "nMethods:n";
for my $meth ($class->methods) {
print " o ", $meth->name, $/;
$meth->call($thingy);
}

Class::Meta provides an interface for automating the creation of Perl classes with attribute data type validation. It differs from other such modules in that it includes an introspection API that can be used as a unified interface for all Class::Meta-generated classes. In this sense, it is an implementation of the "Facade" design pattern.

Wurm Online is 3D FPP MMORPG game.

Online multiplayer role-playing game, where players walk freely in a big 3D world chatting, gathering resources, building towns, making items, trading, fighting with other players and computer controlled creatures. Chose your path - crafting or PvP fighting. Join a village or live solo. Massive skill tree with skill affected by your actions.

Class::Interfaces is a Per module for defining interface classes inline.

SYNOPSIS

# define some simple interfaces
use Class::Interfaces (
Serializable => [ pack, unpack ],
Printable => [ toString ],
Iterable => [ iterator ],
Iterator => [ hasNext, next ]
);

# or some more complex ones ...

# interface can also inherit from
# other interfaces using this form
use Class::Interfaces (
BiDirectionalIterator => {
isa => Iterator,
methods => [ hasPrev, prev ]
},
ResetableIterator => {
isa => Iterator,
methods => [ reset ]
},
# we even support multiple inheritance
ResetableBiDirectionalIterator => {
isa => [ ResetableIterator, BiDirectionalIterator ]
}
);

# it is also possible to create an
# empty interface, sometimes called
# a marker interface
use Class::Interfaces (
JustAMarker => undef
);

This module provides a simple means to define abstract class interfaces, which can be used to program using the concepts of interface polymorphism.

online.php analyses /var/log/ppp-usage and displays connection statistics. It also prints some information about your current PPP connection.
Well, I was inspired by the script Onlinecalc by Michael Schlenstedt (Michael@adsl4linux.de). His script is heavily based upon "calc" by Ulrich Schmitz.
Since Onlinecalc did not fit my needs, I did a complete rewrite in php.
Main features:
- reads /var/log/ppp-usage and prints a table with a row for each month.
- also calculates the values of the current connection.
- completely written in PHP.
- display connect-time as dd:hh:mm:ss
- display volumes as 123 456 789,12 MB
- displays chronologically (maybe I will change the sorting later to reverse)
