Path::Abstract is a fast and featurefull class for UNIX-style path manipulation.

SYNOPSIS

use Path::Abstract;

my $path = Path::Abstract->new("/apple/banana");

# $parent is "/apple"
my $parent = $path->parent;

# $cherry is "/apple/banana/cherry.txt"
my $cherry = $path->child("cherry.txt");

DBIx::SQL::Abstract is a Perl module that provides a convenient abstraction layer to a database.

SYNOPSIS

use DBIx::SQL::Abstract;

my $dbh = DBIx::SQL::Abstract->new( %dbcfg );

Building SQL Abstractions.

my($query, @bind) = $dbh->select($table, @fields, %where, @order);
my($query, @bind) = $dbh->insert($table, %fieldvals || @values);
my($query, @bind) = $dbh->update($table, %fieldvals, %where);
my($query, @bind) = $dbh->delete($table, %where);

Using DBI methods

my $sth = $dbh->prepare($query);
$sth->execute(@bind_params);
...
my $rc = $dbh->begin_work;
my $rc = $dbh->commit;
my $rc = $dbh->rollback;
my $rc = $dbh->disconnect;

Anything else DBI method can be used, by Example:

my $err = $dbh->err;
my $err = $dbh->errstr;
my $rv = $dbh->state;
my $rc = $dbh->DESTROY;

The intention of this module is to join some methods from the DBI and the SQL::Abstract modules, for a convenient and easy use.

To begin, we create an object, but first we must create a hash which contains the database parameters as follows.

my %dbcfg = { PrintError => 1,
RaiseError => 0,
AutoCommit => 0,
ChopBlanks => 1
driver => Pg,
dbname => db,
host => undef,
port => undef,
user => user,
passwd => undef
};

Notice that this parameters are set as default unless you set your required values.
my $dbh = DBIx::SQL::Abstract->new( %dbcfg );

This object automatically creates the connection with the database, and gets the methods listed above.

Libdatastruct is an ANSI C library for abstract data types (ADT) and common algorithms. Since it uses some compiler specific optimization methods, it is compatible for any GCC (or compatible) compiler.

This helps the programmer focus on other, usually more important, aspects of the program, and not have to reinvent the wheel.

Memory has been considered a vital factor, so problems in its management have been (or tried to) avoided, therefore memory leaks, use of uninitialized memory, reading/writing invalid blocks, etc. are a constant preoccupation.

These are not original algorithms, they have been used for years, and are a fundamental part of computer science.

Installation:

make
make install

Usage:

compilation: cc program.c -ldatastruct -Wall -o program

Transcend can best be described as retro-style, abstract, 2D shooter. The graphics are geometrical, and the pace is sometimes frenzied.

Two features set Transcend apart from other games. First, its dynamic graphical engine, which can smoothly morph from one complex shape to another, produces striking displays.

Combining these dynamic shapes with subtle randomizations makes each play through a Transcend level visually different from the last. The second novel feature is Transcends musical power-up system.

As you play through a level, you are simultaneously assembling an abstract visual collage and arranging a unique piece of music. Transcend merges video games with pure art---it can be viewed either as a game or as a multimedia sculpture.

Though I first read it after developing Transcend, the Scratchware Manifesto captures the spirit that motivated me to develop a game.

libscl (SCL) is a library that provides hash tables, list, queue, stack, symbol, balanced binary tree, and a vector as abstract data types.
Multiple independent instances of the same abstract type can be used, each with its own arbitrary contents.
Enhancements:
- Added a little more documentation and some test code.
- SCL should build on Windows with MS Visual C/C++ 6.0, Linux and Solaris with GCC and GNU make.

Basset::Object is a Perl module used to create objects.

This is my ultimate object creation toolset to date. It has roots in Mail::Bulkmail, Text::Flowchart, and the unreleased abstract object constructors that Ive tooled around with in the past.

If you want an object to be compatible with anything else Ive written, then subclass it off of here.

Of course, you dont have to use this to create subclasses, but youll run the risk of making something with an inconsistent interface vs. the rest of the system. Thatll confuse people and make them unhappy. So I recommend subclassing off of here to be consistent. Of course, you may not like these objects, but they do work well and are consistent. Consistency is very important in interface design, IMHO.

Parsec47 is an abstract shooter. I was created by Kenta Cho and ported to Linux by Evil Mr Henry.

Installation:

Parsec47 is entirely contained within this directory. There is no installation. To uninstall, simply delete this directory.

Running:

Type ./p47 to start the game. The command-line line switches listed in readme_e.txt should all work.

Compiling:

Install the OpenGL development libraries. (This is the hard part.)
Install the D compiler, version 0.106. (http://ftp.digitalmars.com/dmd.106.zip) Note that this is non-opensource, so if you cant run the binary, youre out of luck. If you dont like it, talk to digitalmars. I dont like it either. Also, any later versions of the D compiler will NOT work. 0.106 or earlier is needed. As a final note, the resultant binary will not work on other computers, due to problems in the D compiler.

Install SDL_mixer.

Compile with "make". The bulletML libraries will give a few warnings. Ignore them.

Known Issues:

The compiler is non-opensource.

zstar Networked 3D project is a free 3D networked application platform.
zstar (z*) Networked 3D project is an extensible, distributed system for 3D application and game development, consisting of an abstract game client (similar in concept to the one that xpilot uses) and a game server to which players connect to play games against other players or alone.
This framework should be suitable for FPS, VR, MUDs, or any application that requires 3D and networking.
Enhancements:
- Added java interfaces for camera/object messages
- Added walk system
- Added ac3d/sgi rgb loading
- Bug fixes
- Bug fixes on the chat
- Added texture cache and object cache.
- Mipmaps are now in for voodoo users.
