Projects

Lua

Lua is a powerful, fast, light-weight, embeddable scripting language. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine ... [More] , and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping. [Less]

Erlang

Erlang is a programming language designed at the Ericsson Computer Science Laboratory. Ericsson released the entire source code of the Erlang system including extensive libraries of code for building robust fault-tolerant distributed applications.

Tcl/Tk

Tcl (Tool Command Language) is a very powerful but easy to learn dynamic programming language, suitable for a very wide range of uses, including web and desktop applications, networking, administration, testing and many more. Open source and business-friendly, Tcl is a mature yet evolving language ... [More] that is truly cross platform, easily deployed and highly extensible. Tk is a graphical user interface toolkit that takes developing desktop applications to a higher level than conventional approaches. Tk is the standard GUI not only for Tcl, but for many other dynamic languages, and can produce rich, native applications that run unchanged across Windows, Mac OS X, Linux and more. [Less]

CLISP - an ANSI Common Lisp

GNU CLISP is an ANSI Common Lisp implementation with an interpreter, compiler, debugger, object system (CLOS, MOP), sockets, fast bignums, arbitrary precision floats, and foreign language interface which runs on most UNIXes and Win32.

Boo Programming Language

A wrist-friendly language targeting the Common Language Runtime (.NET / Mono) with an extensible compiler pipeline, a syntax reminiscent of Python, and many other features (like type inference, syntactic macros, etc.)

Squeak

Squeak is a modern, open source full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change. Squeak is the vehicle for a wide range of ... [More] projects from multimedia applications, educational platforms to commercial web application development. [Less]

Racket

Programming language suitable for implementation tasks ranging from scripting to application development, and supporting the creation of new programming languages. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, and various other tools.

Pharo

Pharo's goal is to deliver a clean, innovative, free open-source Smalltalk-inspired environment. By providing a stable and small core system, excellent dev tools, and maintained releases, Pharo is an attractive platform to build and deploy mission critical Smalltalk applications.

ArmedBear Common Lisp (ABCL)

ABCL is an implementation of Common Lisp (CL) running in the JVM: it can run in the same JVM as your Java code, allowing full mixture of Lisp and Java code. Being a full CL implementation, it runs many existing libraries and applications, such as Maxima, a computer algebra system. With support for ... [More] JSR-223, you easily extend any JSR-223 compatible application with Lisp as a macro language. This includes integration with the Ant build system using its script-tag. Note: Ohloh indicates few source code comments, based on an average of 32% comment ratio in Java projects. However, in Lisp projects, 19% is much more common. ABCL is nearly 50% Lisp, so the comment rating is underrated. [Less]

Io Language

Io is a small, prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects), Self (prototype-based), NewtonScript (differential inheritance), Act1 (actors and futures for concurrency), LISP (code is a runtime inspectable/modifiable tree) and Lua (small, embeddable).
