Free modula 2 programming language software for linux

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.

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.

The Blue Programming Language project is a unique bytecode-compiled language that implements the most effective capabilities of many popular programming languages in a clear and concise syntax. Plugin modules are easy to develop and can add functions, types, and even programming paradigms to the language without interfering with the syntax.
Blue is still early in its early development stage so very little optimization has been done, and its functionality grows every day. The following introduction is by no means a comprehensive description of blues capabilities.
Main features:
- Free (GPLd)
- A cross-platform programming language
- A dynamic language with a simple and consistant syntax
- Bytecode compiled
- Garbage collected
- Incredibly easy to expand with native functionality
Installation:
- Download the source
- Extract the archive. "tar -xvzf blue1.0.tar.gz"
- cd into the extracted directory. "cd blue"
- Execute make. "make"
- su to root. "su root"
- Execute make install 1. "make install"
- Execute make test. "make test"
Replace "make install" command with "make install INSTALL_DIR="/different/dir" to install to an alternate location.
Enhancements:
- This update contains a compiler bugfix, many more tests, and a function call optimization.

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.
