Felix is an advanced Algol like procedural programming language with a strong functional subsystem. It features ML style typing, first class functions, pattern matching, garabge collection, polymorphism, and has built in support for high performance microthreading, regular expressions and context free parsing.

The system provides a scripting harness so the language can be used like other scripting languages, but underneath it generates native code to obtain high performance.

A key feature of the system is that it uses the C++ object model, and provides an advanced binding sublanguage to support integration with C++ at both the source and object levels, both for embedding C++ data types and functions into Felix, and for embedding Felix into exitsing C++ architectures.

The Felix compiler is written in Objective Caml, and generates ISO C++ which should compile on any platform.

Transmuter Programming Language is an extremely dynamic, biologically-inspired prototyping language providing a framework for experimenting with naturally evolving systems of objects over the net, and for exploring new ideas about recombinant software, code morphing, and evolutionary programming.
Trans is also a very capable general-purpose programming language. Its fast, flexible, compact, object-oriented, highly extensible, and easy-to-learn. It can be used for rapid prototyping, or as a scripting language, an embedded language, a network server or client, a system of cooperating network nodes, a real-time control and monitoring system, and more.
Trans is not only typeless, but also classless. Instead of defining static classes, existing objects serve as prototypes for new objects. New objects are then extended or modified as desired. This modification can occur both statically at compile-time, or dynamically at run-time. Unlike most earlier prototyping languages, Trans uses a concatenation-based prototype system, with no pointers to parent object chains. Parent objects are simply copied into the new object being constructed, allowing for much faster references to inherited members and better object encapsulation. Inheritance is fine-grained, implemented at the member level rather than the object level.
Objects can be saved and loaded externally either as Trans source code, or in bytecode format in network byte-order (as in Java). All Trans source code is compiled to an internal bytecode representation before execution. Since the Trans compiler and interpreter are completely integrated, the compiler is directly accessible to the interpreter at run-time, and the interpreter is also directly accessible to the compiler at compile-time, allowing for complex macro constructs and expressions. Trans uses a fast single-pass compiler, allowing source code to be passed over the net to any Trans instance or server, with little impact in performance.
Trans includes support for integers, floating point numbers, ANSI and Unicode (UTF-16) strings, many builtin functions (including File I/O and TCP/IP Sockets), user-defined functions, and native functions. All functions are atomic objects, and can be passed around and manipulated like any other data item. Builtin functions are treated like user-defined functions, and must be defined before they are used. Native functions located in already-compiled external libraries can also be defined, called, and manipulated like any other data item, with type conversions handled automatically by Trans. And since Trans is implemented as a runtime library with an external API, it can also be embedded in other software environments, such as Java.
Trans also includes a rich assortment of operators, expressions, and statements. Many of these will be familiar to C and Java programmers, but there are significant additions, enhancements, and contextual differences. There are also several important modifiers controlling the disposition of members within an object at compile-time and run-time. A powerful regular expression engine similar to the engines found in Perl, Python, and other languages is also provided. Multiple threads are supported via a simple deterministic threading model.
Trans is relatively lightweight, designed to consume minimal resources such CPU, memory, disk, bandwidth, etc - an important feature in performance-critical real-time environments. The compiler and interpreter are written in C++ and integrated into one library module, using only standard C libraries and Berkeley v1.1 sockets, with no other dependencies. As much as possible, Trans is designed to be operating system and hardware independent, and is currently implemented on the Win32 and x86 Linux operating systems.
The design of Trans was influenced by many other languages, including C/C++, Java, JavaScript, Lisp, Self, Python, Ruby, Perl, and others.
Enhancements:
- This substantial release includes a new x86 Linux version, many language and built-in function enhancements, new optional syntaxes, true aliases, enhanced macro code generation/construction, restructured and restyled import objects and shell, library objects, more detailed examples, a new external API, and increased stability and speed.

Generic Protocol Framework aims to allow users to rapidly prototype different emerging communications protocols. Implementations can be easily "dropped in" and tested independant of a finished product. Testing on both the end product, and the protocol itself can be easily accomplished. The tool aims to provide the developer and end user with a robust solution which can track the size of messages, how rapidly they will be generated, and how many of each type can be seen.
Why the GPF:
There are many similar tools available. The problem with many of these tools is that they are 1) closed source, 2) not easily adaptable to a specific implementation (they use custom languages), 3) expensive. The advantages of the GPF are its open source nature, the ease of which it can be adapted, and the cost: free!
Basic Flow:
Modification of the GPF is fairly simple. Tool-opts.h contains the basic options that will be applied to the packet while it is being built. To transmit a packet, the system calls the tx_message() function, and passes the message ID as well as the option block. This is then passed to the custom function: tx_message_custom() in tx.c. From the message id, the system selects an appropriate tx_* function (to be implemented by the user) and passes an unsigned char **, where the buffer will be written, and the option block. In turn, that function will make heavy use of the add_buf_tu*() functions, which will allow the user to add a tubyte8, tuint16, or tuint32 number to the buffer.
In daemonize mode, the basic options are set, and the system then listens for incomming packets. When a packet arrives, the system calls basic_parse() on the packet. This function then calls basic_parse_custom(), found in parse.c. In turn, this can call any appropriate parsing helpers, including the get_tu*() functions, which allow the user to retrieve a tubyte8, tuint16, or tuint32 from the buffer. CAVEAT: if the first two bytes of the buffer are zerod, it will be treated as an END message. However, recovery is available. In the basic_parse_custom() message, you can set the end_signal_caught variable of the option_block to 0. In this case, it will not stop the daemon from running.
Enhancements:
- Currently, TCP support is somewhat experimental.
- Testing for that portion will be ongoing.
- No clear examples are provided.
- The examples/ directory contains the precursors to a MIP example.

- Support for Java bytecode analysis and transformation has been added.

PATH is a very different programming language than what you are probably used to if youre an average programmer. If youve programmed in the language Brainf*ck, youll recognize the memory cell architecture. Also, Befunge programmers will recognize the two-dimensional way that PATH programs are laid out.

PATH programs are laid out on a two-dimensional grid. It follows a path of instructions on the program grid, turning 90 degrees when instructed to (hence the name). A character recognized by the interpreter is called an instruction symbol.

To show you what a PATH program actually looks like, heres a simple program that coincidentally spells out the word "PATH" in large ASCII art letters. (You may recognize it from the PATH program homepage, and its also included with the interpreter.) All it does is make the console beep. Ill explain it in detail later, once you know what all the instruction symbols do.

The interpreter starts at the first "$" symbol it finds and starts heading right. Every time it encounters a valid instruction symbol, it executes it. When it encounters certain special symbols, it may turn in another direction.

The interpreter keeps going until it reaches a "#" symbol. If it encounters a character that is not a valid instruction symbol, it ignores it and skips over it.
