Database Functions is a PHP class that can be used to build and execute MySQL database queries.

It can build SELECT, INSERT, UPDATE and DELETE queries from lists of parameters and values.

The class can also execute the generated queries and retrieve the SELECT query results into associative arrays.

classes::Test are functions to help with classes pragma testing.

SYNOPSIS

can_new
can_set_get
has_decl
has_class_const
has_mixins
has_mixins_hash

is_classes MyClass;
is_classes main;

is_throwable X::Mine;
is_classes_exc X::Mine;

Generic tests based on Test::Builder designed to help write unit tests for code that uses the classes pragma.

Rauls classes for PHP is an OOP database abstraction layer for PHP 5.1 or greater. Rauls classes for PHP provides abstract classes to access database servers and traverse result sets.
There are several implementation classes to access different types of databases: SQLite, MySQL, PostgreSQL, and MSSQL.
The classes provide functions to establish connections, execute queries, traverse result sets with pagination support, and retrieve the list of databases, tables and fields. Any possible error is signaled by throwing exceptions with specific message and error code.
Enhancements:
- A quickref.txt file was added to the project.
- A totalRows get property was included for SQL result objects.
- A third optional parameter was added to the printPageSelect method in order to return the page < select > code as an string instead of printing it.

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.

Class::Adapter::Builder is a Perl module that can generate Class::Adapter classes.

SYNOPSIS

package My::Adapter;

use strict;
use Class::Adapter::Builder
ISA => Specific::API,
METHODS => [ qw{foo bar baz} ],
method => different_method;

1;

Class::Adapter::Builder is another mechanism for letting you create Adapter classes of your own.

It is intended to act as a toolkit for generating the guts of many varied and different types of Adapter classes.

For a simple base class you can inherit from and change a specific method, see Class::Adapter::Clear.

std_utils is a small library of utility functions and classes.
std_utils library supports string operations such as a stripper of leading or trailing characters and tokenizer, and a configuration file parser.
Enhancements:
- A type to throw exceptions on cConfig was added.
- An isKey() function was added to cConfig.
- The documentation was completed. cLog was removed as you can get the same behavior using fstream with "flush" at the end, which is more efficient.
- The deprecated gettok() was removed.
- A reentrant version of gettok was included to avoid copies.
- "stdu" was added as an alias to the "std_util" namespace.

NamespaceSim project can be used to emulate class namespaces under PHP 5.
It parses PHP code to extract namespace definition statements. The code is rewritten to emulate the namespace support in a way similar to the Java language namespace support.
This package implements new commands named package and import. The package command defines the package that a class belongs. The package name is prepended to the class names using PEAR class naming and directory conventions.
The import command indicates that the package should be imported for use in the PHP script on which the import command is used. Classes that are not found in the current script are looked in the imported namespaces.
Error mapping has been added since 0.4.0, which requires that caching is enabled. This features makes php errors in rewritten files point to the right place in the original file.
As of version 0.5.0 nsim supports namespaces in:
- class definition (w/inheritance & interfaces implementation)
- interface definition (w/inheritance)
- static class vars & functions
- class constants
- instanceof operator
- type hinting

Class::Meta::Declare is a Perl module deprecated in favor of Class::Meta::Express.

SYNOPSIS

This was a first attempt at making a saner interface for Class::Meta. It is nicer, but Class::Meta::Express is nicer still. Go use that one.

package MyApp::Thingy;
use Class::Meta::Declare :all;
use Data::UUID;

Class::Meta::Declare->new(
meta => [
key => thingy,
accessors => $ACC_SEMI_AFFORDANCE,
],
attributes => [
pi => {
context => $CTXT_CLASS,
authz => $AUTHZ_READ,
default => 3.1415927,
},
id => {
authz => $AUTHZ_READ,
type => $TYPE_STRING,
default => sub { Data::UUID->new->create_str },
},
name => {
required => 1,
type => $TYPE_STRING,
default => No Name Supplied,
},
age => { type => $TYPE_INTEGER, },
],
methods => [
some_method => {
view => $VIEW_PUBLIC,
code => sub {
my $self = shift;
return [ reverse @_ ];
},
}
]
);

my $object = MyApp::Thingy->new;
print MyApp::Thingy->pi; # prints 3.1415927
print $object->name; # prints "No Name Supplied;
$object->set_name("bob");
print $object->name; # prints "bob"

This class provides an alternate interface for Class::Meta.

Class::Meta is a useful module which allows one to create Perl classes which support introspection (also known as reflection). Typically Perl classes, when created, dont supply a lot of metadata. Imported helper functions show up when you call $object->can($method). Private, protected and trusted methods are not readily supported. Fetching a list of attributes or methods is a haphazard affair. Class::Meta overcomes these shortcomings by building the classes for you and allowing you to fetch a class object:

my $class_object = $object->my_class;

foreach my $attribute ( $class_object->attributes ) {
print $attribute->name, "n";
}
foreach my $method ( $class_object->methods ) {
print $method->name, "n";
}

If youve set up your class correctly, these properties are now easy to discover.

Unfortunately, many find the Class::Meta interface to be a bit clumsy. As an alternative, Class::Meta::Declare allows you to declare your entire class in a single argument list to the constructor and have the class built for you automatically. Further, reasonable defaults are provided for just about everything.

IMPORTANT: You want this class or Class::Meta if you need an introspection API for your classes. If you do not need introspection or dynamic class generation, these modules are overkill.
