Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
Kalisko is an application framework. Its modular architecture allows applications to easily be built from several individual components. The current development focuses on the implementation of an IRC client, though other kinds of software are possible in the future. Features (already implemented modules) include: a small core application with a simple but powerful module system that runs on Windows and Linux; a simple IRC client using GTK+ for visualization; scripting support in Python, PHP, and Lua; a Lua console; a PHP console (Linux only); a powerful serializable data structure that can be stored in memory or written to files; a cross calling interface (xcall) that allows functions to be called and defined in and from any language; and many more.
SparForte is a scripting language for large projects requiring reliable, scalable code, reduced maintenance time, and strong bug elimination requirements. It is targeted for programmers interested in quickly writing reliable software, educators wanting to teach disciplined programming skills, and advocates of the Ada/Spark programming languages.
