Calendario Class is a PHP class that helps you to create calendar and organizers.
Its highly configurable, letting you choose how many days are in a week, when a week starts, the details of the HTML output, and so on.
It also knows about holidays.
Enhancements:
- Added holidays functionality

Access_user Class is an easy to use system for protecting pages and registering users. The main features are user login, user registration, page protection, forgotten password recovery, and email-based account activation.
The class is powered by MySQL and PHP sessions. Inside the package are examples for all primary methods.
Enhancements:
- Its now possible to store the session data in your database.
- This is much safer if you use sessions on a shared hosting server.
- The password is always encoded with MD5 now.
- session_destroy() was added to the logout method.
- The links used in the email messages are now double MD5-encoded.

Installation Instructions:

• pt-helper is written in Python, so you'll need a Python interpreter to get anything working. It also depends on several Python modules;
• If you do have all the dependencies, you should be able to run the program just by running the pt-helper script with a Python interpreter. From a shell, the following command should do the trick: $ python pt-helper.py
  
• Users of graphical file managers can probably double-click the pt-helper script to achieve the same effect.

Requirements:

• Python
• PyGame
• Festival Speech Synthesis System

Gtk2::Helper is a Perl module for convenience functions for the Gtk2 module.

SYNOPSIS

use Gtk2::Helper;

# Handle I/O watchers easily, like Gtk 1.x did
$tag = Gtk2::Helper->add_watch ( $fd, $cond, $callback, $data )
$rc = Gtk2::Helper->remove_watch ( $tag )

ABSTRACT

This module collects Gtk2 helper functions, which should make implementing some common tasks easier.

Gtk2::Helper->add_watch ( ... )

$tag = Gtk2::Helper->add_watch ( $fd, $cond, $callback, $data )

This method is a wrapper for Glib::IO->add_watch. The callback is called every time when its safe to read from or write to the watched filehandle.

$fd

Unix file descriptor to be watched. If you use the FileHandle module you get this value from the FileHandle->fileno() method.

$cond

May be either in or out, depending if you want to read from the filehandle (in) or write to it (out).

$callback

A subroutine reference or closure, which is called, if you can safely operate on the filehandle, without the risk of blocking your application, because the filehandle is not ready for reading resp. writing.

But aware: you should not use Perls builtin read and write functions here because these operate always with buffered I/O. Use low level sysread() and syswrite() instead. Otherwise Perl may read more data into its internal buffer as your callback actually consumes. But Glib wont call the callback on data which is already in Perls buffer, only when events on the the underlying Unix file descriptor occur.

The callback subroutine should return always true. Two signal watchers are connected internally (the I/O watcher, and a HUP watcher, which is called on eof() or other exceptions). Returning false from a watcher callback, removes the correspondent watcher automatically. Because we have two watchers internally, only one of them is removed, but probably not both. So always return true and use Gtk2::Helper->remove_watch to disable a watcher, which was installed with Gtk2::Helper->add_watch.

(Gtk2::Helper could circumvent this by wrapping your callback with a closure returning always true. But why adding another level of indirection if writing a simple "1;" at the end of your callback solves this problem? ;)

$data

This data is passed to the callback.

$tag

The method returns a tag which represents the created watcher. Later you need to pass this tag to Gtk2::Helper->remove_watch to remove the watcher.

WebServerInfo PHP class is intended for developer who create software that will run
on different web servers. The project gives a developer a consistent interface
for accessing web servers variables.

Usage:

You have following options:

Option #1
require_once("WebServerInfo.class.php");
$obj = new WebServerInfo();
print $_SERVER[DOCUMENT_ROOT];

Option #2
require_once("WebServerInfo.class.php");
$obj = new WebServerInfo();
print $obj->get(DOCUMENT_ROOT);

Option #3
uncomment the 3rd line from WebServerInfo.class.php
and all you have to do is require the WebServerInfo.class.php class.

Note:
The constructor of WebServerInfo class overrides $_SERVER variable and
variables can be accessed as usual way.


Following base variables are exported if they do not exist.

REQUEST_URI
REDIRECT_URL
DOCUMENT_ROOT
SERVER_SIGNATURE
SERVER_ADDR
SCRIPT_FILENAME

Test::Unit::InnerClass is a unit testing framework helper class.

SYNOPSIS

This class is not intended to be used directly

This class is used by the framework to emulate the anonymous inner classes feature of Java. It is much easier to port Java to Perl using this class.

PHP Advanced Graphing Class is a PHP class that can be used to generate line, bar, and 2D/3D pie graphs from multiple data sets. PHP Advanced Graphing Class offers many style and data formatting options.
The graphs can be built from data defined with PHP code or with data imported from XML or CSV files. It can use custom colors, custom data point shapes or images, custom end arrows, an optional inline format, a custom graph scale, etc.
The graphs can be generated in PNG format either to a file or served as the current script output.
Enhancements:
- Bar charts and 2D/3D pie charts were added.

squid-nufw-helper is the authentication Single Sign On module for Squid, working with a NuFW firewall. The project allows for transparent authentication of users on a Squid proxy, even if the proxy is a "transparent" one.
Enhancements:
- This release adds an "-a" switch to pass the clients source port to htons() at will (this is required by some versions of squid, but not all).
- This release is marked as stable, as it has been extensively tested.
