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.

wsdebug is a debugger for the more or less famous whitespace programming language, coming along with a rather fast interpreter (wsi).

Most programming languages like C or Perl do not care for white space characters (like tab, space or newline/linefeed). The whitespace programming language works just the other way round, dont care for any character but those white space ones.

On the whole its just another geeky language like Brainfuck and others, however more adicting.

If youve written a whole lot of instructions youll probably reach the point, where you get lost. Then just put your script into wsdebug and step through your bunch of whitespace instructions and watch how each command manipulates the stack (or heap).

Lfyre is a programming language and the interactive compiler for the same language.
Its key features are flexibility, performance and simplicity.

For instance, lfyre code can be compiled or interpreted and can define new language keywords and operators.

Lfyre programming language and interactive compiler aim at many things at once:

first of all, the compiler is really interactive: you can compile, uncompile, run and debug source code from its prompt.

second, lfyre aims at filling the gap between low and high level languages by a modular approach:
the compiler provides a minimal set of features, most notably support for basic types and extensions, while modules written in lfyre provide the rest:
most keywords and operators, classes library, etc.

Lfyre code can be compiled (at the moment by translating it into C) or interpreted by a high performance virtual machine built in the compiler. The virtual machine is used by the compiler to execute and debug source code interactively, or while compiling (this allows a program to define new keywords, whose associated code must run while compiling).

All parts of the compiler (parser, resolver, C and vm translators, virtual machine) can be programmatically accessed from lfyre code. For example, a program can reuse lfyre parser to read a configuration file or can compile some modules at run-time and load them.
Or even, a program may load untrusted or untested code and run it safely inside the virtual machine.

Lfyre interactive compiler is portable, except for some exotic techniques used to speedup the virtual machine. Such speedups can anyway be disabled, obtaining fully portable code.

Lfyre compiled code aims and is expected to run at least as fast as hand-written C.

From the downside, lfyre is a "classic" procedural language with templates, reflection and single inheritance. Some features typical of functional languages are being investigated but are probably out of scope.

The name "lfyre" is a shortcut of Lfyre - a Language designed for FlexibilitY, Reflection and Extensibility.

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.

ECF is a framework developed to build web applications in an easy way. ECForms goals can be enumerated as follows:
Main features:
- Develop dynamic web applications in an easy way.
- Focus the programming on the real problem, not on the programming details.
- To have a programming language based on Java.
- To have the same qualities of the JavaServer Faces framework.
- To have a mechanism to store data in an easy way.
- To have extensible characteristics.
- To reduce the programming time.
ECF is a programming language based on IPL (IENJINIA Programming Language), IDB and JSF (JavaServer Faces) developed to build web applications.

Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way.
Scala smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more.
It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
Scala is a pure object-oriented language in the sense that every value is an object. Types and behavior of objects are described by classes and traits. Class abstractions are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance.
Whats New in 2.6.0 RC1 Development Release:
- This version introduces some language changes (existential types, lazy values, structural types, etc.) and fixes many bugs.

jstree is a JavaScript that allows you to see the entire DOM tree of a selected object.

The object can be selected by ID or as an object variable.

JavaScript is an object-based scripting programming language based on the concept of prototypes. The language is best known for its use in websites, but is also used to enable scripting access to objects embedded in other applications.

Despite the name, JavaScript is only distantly related to the Java programming language, the main similarity being their common debt to the C programming language.

JavaScript has far more in common with the Self programming language.
JavaScript is a registered trademark of Sun Microsystems, Inc., used under license for technology invented and implemented by Netscape.

yUba is a Hybrid Programming Language for easy Web application development.
yUba is a programming language suitable for Web application development, which produces both Perl and Javascript codes from one language.
yUba creates both client-side code (JavaScript) and server-side code (Perl) at once. XML/HTML can be embedded directly in yUba code without any quotations.
Enhancements:
- Some compiler bugs were fixed.
