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

Scriptio project is an open source framework for presenting animations and educational content in a rich online experience.
Featuring an easy-to-learn scripting language for fast prototyping and production-quality development, Scriptio is designed for rich Web 2.0 applications.
Scriptio is written in JavaScript, and exploits Ajax techniques. Ajax refers to tools and methods for creating interactive web applications. If accompanying narration or sound is needed, interfaces to Flash, QuickTime, and standard audio formats are supported.
Main features:
Intuitive scripting language
- The scripting language is a simple and easy to understand. It can also be extended since it is built in JavaScript.
Rich object set
- Text, images, rectangles, lines, and circles are supported. Input controls such as buttons, text entry fields, radio buttons, and checkboxes are used for created highly-interactive instructional presentations.
Multiple audio options
- If you need a music or narration soundtrack, interfaces for QuickTime and Flash are included. A Java applet that supports audio formats of Ogg, AU, and WAV has also been developed.
Authoring Tools
- An "author mode" gives valuable feedback as you work and develop your scripts.

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.

Sleep is a perl inspired embed-able scripting language for Java applications.
Sleep source and binaries are released under the GNU Lesser General Public License.
Main features:
- Perl inspired language syntax
- Fast execution / small runtime size (170 KB)
- Parsed scripts can be serialized
- Easy API for making application data structures / functionality available to scripters
- Access, create, and query Java objects from Sleep scripts
- Full documentation for application developers and end-user scripters
Enhancements:
- Scalar reference sugar was added for moving scalars between scopes
- The backtick operator was added to spawn an external program (a la Perl).
- Java method resolution was updated to handle byte and char arrays better.
- Set functions now rely on scalar identity for union, intersect, and difference.
- Class/package importing is now more verbose about errors.

UTF8Script provides an additional binary format for Linux: scripts that start with a UTF-8 signature (aka BOM), i.e. with the byte sequence xefxbbxbf#!.

This is particularly useful for scripting languages that recognize the BOM, e.g. Python. With Python 2.3 or newer, scripts with the UTF-8 BOM are considered UTF-8 enocded without the need for an addition encoding declaration.
