Time::Piece is a Perl module that contains Object Oriented time objects.

SYNOPSIS

use Time::Piece;

my $t = localtime;
print "Time is $tn";
print "Year is ", $t->year, "n";

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards compatible manner, so that using localtime/gmtime in the way documented in perlfunc will still return what you expect.

The module actually implements most of an interface described by Larry Wall on the perl5-porters mailing list here: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-01/msg00241.html

USAGE

After importing this module, when you use localtime or gmtime in a scalar context, rather than getting an ordinary scalar string representing the date and time, you get a Time::Piece object, whose stringification happens to produce the same effect as the localtime and gmtime functions. There is also a new() constructor provided, which is the same as localtime(), except when passed a Time::Piece object, in which case its a copy constructor. The following methods are available on the object:

$t->sec # also available as $t->second
$t->min # also available as $t->minute
$t->hour # 24 hour
$t->mday # also available as $t->day_of_month
$t->mon # 1 = January
$t->_mon # 0 = January
$t->monname # Feb
$t->month # same as $t->monname
$t->fullmonth # February
$t->year # based at 0 (year 0 AD is, of course 1 BC)
$t->_year # year minus 1900
$t->yy # 2 digit year
$t->wday # 1 = Sunday
$t->_wday # 0 = Sunday
$t->day_of_week # 0 = Sunday
$t->wdayname # Tue
$t->day # same as wdayname
$t->fullday # Tuesday
$t->yday # also available as $t->day_of_year, 0 = Jan 01
$t->isdst # also available as $t->daylight_savings

$t->hms # 12:34:56
$t->hms(".") # 12.34.56
$t->time # same as $t->hms

$t->ymd # 2000-02-29
$t->date # same as $t->ymd
$t->mdy # 02-29-2000
$t->mdy("/") # 02/29/2000
$t->dmy # 29-02-2000
$t->dmy(".") # 29.02.2000
$t->datetime # 2000-02-29T12:34:56 (ISO 8601)
$t->cdate # Tue Feb 29 12:34:56 2000
"$t" # same as $t->cdate

$t->epoch # seconds since the epoch
$t->tzoffset # timezone offset in a Time::Seconds object

$t->julian_day # number of days since Julian period began
$t->mjd # modified Julian date (JD-2400000.5 days)

$t->week # week number (ISO 8601)

$t->is_leap_year # true if it its
$t->month_last_day # 28-31

$t->time_separator($s) # set the default separator (default ":")
$t->date_separator($s) # set the default separator (default "-")
$t->day_list(@days) # set the default weekdays
$t->mon_list(@days) # set the default months

$t->strftime(FORMAT) # same as POSIX::strftime (without the overhead
# of the full POSIX extension)
$t->strftime() # "Tue, 29 Feb 2000 12:34:56 GMT"

Time::Piece->strptime(STRING, FORMAT)
# see strptime man page. Creates a new
# Time::Piece object

Php Object Generator on short POG is an open source PHP code generator which automatically generates clean & tested Object Oriented code for your PHP4/PHP5 application.
Over the years, we realized that a large portion of a PHP programmers time is wasted on repetitive coding of the Database Access Layer of an application simply because different applications require different objects.
By generating PHP objects with integrated CRUD methods, POG gives you a head start in any project and saves you from writing and testing SQL queries. The time you save can be spent on more interesting areas of your project. But dont take our word for it, give it a try!
Main features:
- Generates clean & tested code
- Generates CRUD methods
- Compatible with PHP4 & PHP5
- Compatible with PDO
- Free for personal use
- Free for commercial use
- Open Source
Enhancements:
- POG now fetches result set arrays where possible (which provides a big performance boost).
- Data encoding is handled within the database.
- A new plugin interface is used.
- A data encoding sanity check was added to setup.
- Siblings can be deleted without deleting children.
- Getlist() accepts column names as filters.
- Getlist(), GetChild(), and GetSibling() return all results if no arguments are passed.
- A database wrapper class for PDO was added.
- The PDO performance was improved.
- The plugin API, POG base API, and database API were made uniform to prevent plugin versioning.

ogre4j project enables the use of the OGRE (Object-Oriented Graphics Rendering Engine) libraries in Java applications.

The first approach was made by Ivica Aracic aka bytelord (http://www.bytelords.de). Thanks to him for taking the first steps!
The last stable CVS version located at the OGRE SourceForge.net project page is based on his code but the new team is working on a complete new version that will be more powerful (hopefully).

To ease the pain for those who are using OGRE in C++ the usage of ogre4j will be straight forward. Every public interface of the OGRE library will be available through Java Native Interface (JNI) in the Java world.

Math::Vec is a Object-Oriented Vector Math Methods in Perl.

SYNOPSIS

use Math::Vec;
$v = Math::Vec->new(0,1,2);

or

use Math::Vec qw(NewVec);
$v = NewVec(0,1,2);
@res = $v->Cross([1,2.5,0]);
$p = NewVec(@res);
$q = $p->Dot([0,1,0]);

or

use Math::Vec qw(:terse);
$v = V(0,1,2);
$q = ($v x [1,2.5,0]) * [0,1,0];

NOTICE

This module is still somewhat incomplete. If a function does nothing, there is likely a really good reason. Please have a look at the code if you are trying to use this in a production environment.

The Complex Language project is an object oriented programming language intended for scripting or rapid prototyping of applications.
The design goals were to have very few simple but powerful concepts and to be easy to use and easy to learn. The project provides a working interpreter along with a complete specification of the language.
Enhancements:
- This is the first release of the specification and the corresponding interpreter.
- The corresponding library is very poor, and there are probably still bugs in the interpreter.

Achievo ATK is an object oriented Web-application framework. Achievo ATK is targeted at developers who wish to focus on business logic instead of coding HTML.
Where other application frameworks mainly provide a large set of utility classes, ATK provides a complete framework that requires only small amounts of code to get usable applications, while maintaining full flexibility.
In other words, even 10 lines of code get you a working application, but everything that is generated for you can be completely customized.
Main features:
- Modular architecture
- GUI and data internationalisation
- Application level record locking
- Minimum amount of required coding
- Fully customisable
- Themable
- Template driven
- Database abstraction
- GUI abstraction
- User-based, group-based, level-based or custom security schemes
Enhancements:
- AJAX and JSON functionality were added.
- Transparent MySQL replication support and Oracle Savepoints support were added.
- Fixture support was added.
- The GUI has been improved significantly.
- CAPTCHA functionality was added.
- A generic class overloading mechanism was added.
- Over 400 other enhancements and fixes were made.
