JRuby is a 100% Java implementation of the Ruby programming language. It is Ruby for the JVM, offering high performance, real threading and support for vast array of libraries. JRuby is highly compatible with Ruby 1.8.7 & 1.9.2 (both versions in single install).

KTurtle is an educational programming environment for KDE. KTurtle aims to make programming as easy and touchable as possible, and therefore can be used to teach kids the basics of math, geometry and... programming. The programming language used in KTurtle is loosely based on Logo. KTurtle allows, just like some implementations of Logo, to translate the programming language (the commands, the documentation and the error messages) to the native language of the programmer. Translating the programming language to the native language of the programmer is one of the many ways KTurtle tries to make learning to programming more simple. Other features to help to achieve this goal are: intuitive syntax highlighting, simple error messages, integrated canvas to make drawings on, integrated help function, slow-motion or step execution, and more.

These are bindings to a Lua library for Ada. The gpr file is written for the version of Lua that is default on the system that builds the port. (see Mk/bsd.default-versions.mk) There is no documentation available, but two examples with sources are built and installed for illustration.

Lua is a programming language originally designed for extending applications, but also frequently used as a general-purpose, stand-alone language. Lua combines simple procedural syntax (similar to Pascal) with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from bytecodes, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping. A fundamental concept in the design of Lua is to provide meta-mechanisms for implementing features, instead of providing a host of features directly in the language. For example, although Lua is not a pure object-oriented language, it does provide meta-mechanisms for implementing classes and inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the language small, while allowing the semantics to be extended in unconventional ways. Extensible semantics is a distinguishing feature of Lua. Lua is implemented as a small library of C functions, written in ANSI C, and compiles unmodified in all known platforms. The implementation goals are simplicity, efficiency, portability, and low embedding cost.

Awk scans input files for specified patterns and can perform an associated action when a line of the file matches the pattern. This is the One True version of awk described in "The AWK Programming Language" by Al Aho, Brian Kernighan, and Peter Weinberger (Addison-Wesley, 1988, ISBN 0-201-07981-X).

The New Brainfuck Compiler is an optimizing Brainfuck-C and Brainfuck-Java compiler.

The nesasm assembler is a 6502 assembler with specific NES support.

LuaJIT is a Just-In-Time Compiler for the Lua programming language.
