ObjectiveLib is a framework for Objective-C that provides a set of object containers and generic algorithms. It is designed to provide the same services to Objective-C programmers that the Standard Template Library provides to C++ programmers.
All of the standard containers (vector, deque, list, map, set, and others) and standard algorithms from the STL are included. Additionally, a set of iterator classes is provided to connect containers to generic algorithms.
A full set of binary streams is provided, which include file, memory buffer and socket streams, as well as layering streams that can buffer and/or compress data.
Enhancements:
- A complete set of binary streams has been added.
- These include streams that can read and write to/from files, memory buffers, and sockets. Additionally, layering streams are included that can buffer data, compress data (3 compression streams are provided), and manage object graphs written to the stream.
- Some method names that did not conform to the Cocoa naming conventions have been changed.

Caml is a general-purpose programming language, designed with program safety and reliability in mind. It is very expressive, yet easy to learn and use. Caml supports functional, imperative, and object-oriented programming styles.

It has been developed and distributed by INRIA, Frances national research institute for computer science, since 1985.

The Objective Caml system is the main implementation of the Caml language. It features a powerful module system and a full-fledged object-oriented layer.

It comes with a native-code compiler that supports numerous architectures, for high performance; a bytecode compiler, for increased portability; and an interactive loop, for experimentation and rapid development.

Objective Modula-2 programming language is a hybrid between Smalltalk and Modula-2 based on the object model and runtime of Objective-C.

The design is an example how native Cocoa/GNUstep support can be added to static imperative programming languages without implementing a bridge.

The projects scope encompasses the design of the Objective Modula-2 programming language and the implementation of a compiler to implement it. The initial compiler will generate Objective-C source code.

Portable Object Compiler project consists of a set of Objective-C class libraries and a precompiler (translator) that generates plain C code.
Main features:
- Easy to install or to modify.
- Works on many systems with the native cc, debugger, profiler etc. (Unix, Windows, Macintosh, Beos, OpenVMS etc. see Platforms.txt file)
- Option for reference counted memory management (-refcnt). This uses the native malloc(), free() etc. but the compiler generates statements for keeping track of references (Tested on a few platforms, such as IRIX 5.2 with the SGI malloc).
- Built-in possibility of tracing Objective C messages. (OBJCRTMSG)
- Straightforward "C" messenger; "inline cache" messenger. Forwarding C messenger (to support -doesNotUnderstand:).
- All classes get a +initialize message at start-up, rather than each class receives a +initialize before it receives its first message.
- Some support for translating Objective-C to Smalltalk (-st80 option)
- Automatic archiver. Compiler generates code for classes to save and load objects to and from disk (for all instance variables of type "id").
- Option for Garbage Collection (using Boehm gc package). Tested on some UNIXes and WIN32. Option for reference counted memory management (doesnt require Boehm).
- Exception handling scheme (using Objective-C Blocks) that allows to specify a default handler to be executed.
- Supports dynamically loading Objective-C modules on Windows, FreeBSD, HP-UX, Linux, IRIX, Digital Unix etc.
- Has a switch for double indirection for Object identifiers (id as a handle instead of a pointer). (-become: method)
- Supports forwarding messages (-doesNotUnderstand: method)
- Support for Embedded SQL in Objective-C (Informix only for now)
- Great system for experimentation with your own additions/extensions to Objective C !

Debian vs Pimientos is an arcade game developed using the SDL libraries SDL, SDL_image, SDL_mixer, and SDL_ttf. This permits the portability of the game to some systems and machines.
Debian vs Pimientos is the first game of NEOPONTEC Games, and the first to use the NNG Engine (New Neopontec Gaming Engine) developed by Hector Blanco (me) that uses the mentioned SDL Libraries.
The game concept is very easy to understand and to play. There are a lot of peppers (pimientos is the spanish word for peppers) that are flying by the sky, and you, armed with the Debian logo must fight them. The Debian logo shoots GNU heads to kill these devil pimientos
Main features:
- 800x600 resolution at 32 bits.
- High quality images.
- Addictive and funny playing experience
- Cross-platform open source game: (binaries for Win32 & Linux, and sources for other systems).
- Different classes of peppers (pimientos).

Vectoroids project is a vector-based asteroid shooting game in SDL.
Your objective is to maneuver a space ship within a field of asteroids, and shoot them into smaller and smaller pieces, eventually destroying them completely.
Vectoroids is based directly on the code for Agendaroids. It has been ported from X-Window to SDL, so it runs on numerous platforms.
Vectoroids includes music, sound effects, and lots of cool color vector graphics!
Main features:
- Smooth vector graphics
- Rotating asteroids
- Fast, table-based trigonometric functions
- High quality sound effects
- Great music
- Pause and resume (even if you quit)

objc distribution consists of the "VICI", interactive Objective-C debugger and interpreter "objc", the actual compiler.

Consists of driver script ("objc") and binary ("objc1").
"objc1" is a precompiler for C.
The binary "postlink" is used
for preparing tables for runtime initialization.
"objcrt", the Objective C Runtime Library for "objc"

This is a modern, portable, "all C" Objective C runtime

Theres absolutely no assembly language needed, nor is there a dependency on stack layout, register allocation conventions etc.

Most other runtimes, were derived from pre-"all C"-Stepstone runtimes, so this is an important point of difference.

"objpak", the "Object Pak" Objective C Collection Classes

Simple, powerful set of classes. Very portable.
Can be used to develop with different compilers, then
port with objc. Compatible with ICpak101, the collection class library described in Brad Cox book, and used by existing Objective-C packages that were developed with Stepstone objc.

"cakit", the "Computer Algebra Kit" Objective C classes

Small, concise, interface to a large set of classes for polynomial computing and arbitrary precision integer arithmetic.

Source of compiler and "oclib", a set of Objective C classes for parsing C (and the Objective C extensions to C)

"objc" and "vici" are written in Objective C itself. Its all written in portable Objective C : any Objective C compiler should be able to compile the "objc" compiler. From time to time, we try a configure with other Objective-C compilers, to ensure that our sources are still compatible with e.g. Stepstone Objective C compiler.

NOT included is a C compiler : in order to be able to use "objc", you will need to elsewhere find a compatible C compiler. This should be no problem since one of our goals - see below - is to make "objc" work with as many C
compilers as possible. On UNIX systems, the (free) "gcc" compiler is a possibility (not needed, but possible). Another possibility, is to use the (free) "lcc" compiler or the "tcc" TDF compiler system.

Installation:

Read the Install.txt file.

IMPORTANT : if this is a first-time installation, you have to start by installing the bootstrap package; do not install this package until you have installed the bootstrap package.

For every release, there is an objc-x.y.z.tar.gz package and an objc-x.y.z-bootstrap.tar.gz package.

Snoopy vs. the Red Baron is an open-source one/two player combat game, available for Mac OS X, Linux, BeOS, QNX and Windows.
The original Snoopy was a tiny game for the Apple Macintosh, with black and white graphics, but already almost all the levels of the new Snoopy/SDL were implemented.
Snoopy could be played by two opponents, sharing a single screen and keyboard, and although it had poor graphics and tough controls, we very much liked to play it.
While we learned programming, we constantly sought for simple, yet interesting projects. If you have ever tried to learn a new language or API, you will have recognized that the simplest way in mastering the stuff is simply reprogramming an existing application, without losing much thought on design and originality.
So my friend reprogrammed Snoopy, in Object Pascal, using SAT, the Sprite Animation Toolkit, on his Classic II. That version of Snoopy features a fully functional AI, network play, but only the first level ( weapons drop).
While he was at it, he also implemented a "missing feature", the bombs, for which there where graphics and sounds in the game, but which could not be thrown.
When I discovered SDL, I recognized that it would be ideal for the job. Running on Windows, Linux, MacOS, BeOS and many other platforms, it is my new toolkit of choice for multimedia programming. It took us several weeks to port Snoopy (besides going to school, but now the work is almost done, with only the finishing touches to be made.
I can only encourage everyone to try SDL; it is really easy and portable (if worked right).
