Java Unified Expression Language is an implementation of the unified expression language (EL) as specified by the JSP 2.1 standard (JSR-245).
The javax.el.ExpressionFactory implementation is de.odysseus.el.ExpressionFactoryImpl:
// create an expression factory
javax.el.ExpressionFactory factory = new de.odysseus.el.ExpressionFactoryImpl();
Package de.odysseus.el.util provides ready-to-use subclasses of javax.el.ELContext and javax.el.ELResolver:
// create a simple EL context
de.odysseus.el.util.SimpleContext context =
new de.odysseus.el.util.SimpleContext(new de.odysseus.el.util.SimpleResolver());
// define function math:max(int,int)
context.setFunction("math", "max", Math.class.getMethod("max", new Class[]{int.class, int.class}));
// define variable "foo"
context.setVariable("foo", factory.createValueExpression(0, null));
// create expression
javax.el.ValueExpression e = factory.createValueExpression(context, "${math:max(foo,bar)}", null);
// set value for top-level property "bar"
context.setValue(null, "bar", 1);
// evaluate expression...
System.out.println(e.getValue(context)); // --> 1
The JUEL jar may be run from the command line to dump the parse tree of an EL expression:
$ java -jar juel-2.1.x.jar "#{unified(expression[language])}"
+- #{...}

QML (Quantity Modeling Language) is a "thing"-based language for scientific and mathematical data modeling.
Each "thing" is a quantity which may be associated with either a structure or physical phenomena.
Quantities, in turn, may hold other Quantities or values (numbers or strings). Higher-level data models, which associate or define meanings to various quantities (such as velocity or position), can be built from QML quantities.
The higher-level data model (XML) schema that inherits from QML may be understood, and its instance documents may be parsed into QML documents and objects by the QMLReader.
Enhancements:
- This release adds partial Xerces2 DOM support, and works with Java 1.4 and Java 1.5 (no JAXP DocumentBuilder/Factory support currently).
- The test procedure is a little less chatty.
- Support has been added for testing either/both Crimson/Xerces DOM support.
- (Note: Crimson support only works with Java 1.4, as Java 1.5 interfaces have DOM lvl 2 and 3, which crimson doesnt support).
- This release adds compilerargs, and better build support for different configurations to build.xml.

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.

Java::Swing provides a Perl extension providing direct access to the Java Swing API.

Though you can write a Java program which is driven by Perl, some people may prefer to keep their Perl pure. This package lets you do that in manner similar to the way Perl/Tk and Gtk2:: provide access to their underlying libraries. This lets us code in our favorite language, while using the graphical interface capabilities of Java Swing.

Once you use Java::Swing, you can refer to javax.swing classes by their class name alone as if it name were a Perl package name. All class methods, including constructors, can be called as normal through this Perl package name.

But, if you like, you may also use Java::Swing named attribute construction, as shown for the second JTextField above. Simply supply a hash reference whose keys are attributes of the class with the proper values. Your object will be constructed by calling the empty argument constructor. Then the attribute values will be supplied by calling set accessors. So columns => 10 will translate into setColumns(10).

As of version 0.12, you may add an Object attribute to the constructor hash. Then Java::Swing will call the constructor on the underlying class which expects it, and then call set accessors for any additional attributes.
