The Hecl Programming Language is a high-level scripting language implemented in Java. Hecl Programming Language is intended to be small, extensible, extremely flexible, and easy to learn and use.

Hecl is intended as a complement to the Java programming language, not a replacement. As such, it tries to do well what Java doesnt, and leaves those tasks to Java for which it is best suited.

Hecl aims to be a very immediate language - you can pick it up and start doing useful things with it quickly. It is also meant to be easy to learn. Where Java is verbose and rigid, Hecl is forgiving and quick to write. For instance, System.out.println("Hello World"); vs puts "Hello World" - 41 keystrokes (shifted letters count double) versus 22. Hecl is built to "scale down".

This makes Hecl ideal for large applications written in Java that would like to provide a user friendly scripting interface, rather than, say, a clunky XML based configuration system.

Hecl is also a small language with a minimal core. The idea is to provide only whats necessary in the language itself, and as needed, add in extensions for specific tasks.

Core Hecl is small enough to run on my Nokia 3100 cell phone as a J2ME application, presenting the interesting possibility of writing scripts, or at some point, maybe even scripting entire applications, for devices running embedded Java. As an example, you can try this MIDlet: Hecl.jar Hecl.jad

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.

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.

Luban is a component oriented scripting language. Luban is free and open source. Luban is named after a legendary ancient Chinese civil engineer and carpenter two thousand year ago whose constructions are still in use today.
The programming language spectrum seems crowded. Do we have all the tools we need? The author of Luban likes the scripting languages in general because of their usability. Though he always feels the pain for the lack of suitable component model for scripting.
And he personally considers object oriented scripting is too complicated for scripting purpose and will never compete with C++/Java. He eventually created Luban, a scripting language with a robust component model tailored for scripting purpose. Luban is an easy scripting language that is as clean and manageable as Java.
There have been numerous discussions about software component without clear definition. Lubans definition of component is property based object that is similar to Java Bean. User interacts with component by reading and writing property values, and computation could be triggered by the interactions.
The idea of Luban programming language that scripting language needs a different component model other than conventional class hierarchy to fit its scripting environment. A complete mechanism is built in Luban to define, save and categorize components, which is a fundamental feature of Luban.
Enhancements:
- This release adds the new feature to iterate through the elements in Java container objects.
- The following Java types can now be iterated in Luban: Java array, java.util.Collection, and java.util.Map.

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.

The Squirrel programming language is a high level imperative/OO programming language, designed to be a powerful scripting tool that fits in the size, memory bandwidth, and real-time requirements of applications like games. Although Squirrel offers a wide range of features like:
- Open Source zlib/libpng licence
- dynamic typing
- delegation
- higher order functions
- generators
- cooperative threads(coroutines)
- tail recursion
- exception handling
- automatic memory management (CPU bursts free; mixed approach ref counting/GC)
- both compiler and virtual machine fit together in about 6k lines of C++ code.
- optional 16bits characters strings
Squirrel is inspired by languages like Python,Javascript and expecially Lua(The API is very similar and the table code is based on the Lua one).
squirrels syntax is similar to C/C++/Java etc... but the language has a very dynamic nature like python/Lua etc...
local array=[1,2,3,{a=10,b="string"}];
