Free java programming software for linux

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.

KDE Simple Programming Tutorial is a tutorial for developing a KDE application.

With the only requirement of a little C++ knowledge, and using the latest KDE snapshots, the reader will learn how to build his/her first KDE application from a simple "Hello world" button to a Web browser with a DCOP interface that communicates with a bookmark application running in a separate process.

Theres also a spanish and a romanian version of the documentation.

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"}];
foreach (i,val in array)
{
::print("the type of val is"+typeof val);
}
