Co-op is a workbench for the definition and use of composition operators: abstractions that can encapsulate standard solutions such as coding idioms, design patterns and composition techniques, and can later be (re-) used just like library classes.

DelphiWebScript is a scripting language for use in Borland Delphi(tm) projects. The programming language is similar to Delphi. It's HTML features are optimal for web applications and report modules.

NJS is an independent implementation of the JavaScript language developed by Netscape and standardized by ECMA. It is designed to be re-entrant, extendible, fast, and programmable.

CCSH is provides a way of using C programs in the way you use shell scripts. This allows the user to only have to manage 1 file (the source file). This is also useful in heterogenious environments. The code is compiled upon execution. In the fu

EVM is a 32-bit virtual machine designed for easy implementation. It supports bounds checking, real-time linking and JIT compilation on x86 architecture. No platform-specific calls or byte order dependencies. Comes with an optimizing C compiler.

HBasic is an IDE with an interpreter and compiler used to create, execute and debug programs with a BASIC style language. The language includes object oriented features and may be compiled to interpreter pcode and standalone executables.

Lemick is a project to make a programming language similar to those traditional Basic implementations but with all the attributes of the modern programming tool

Sepi is an object-oriented scripting engine for Delphi. It allows the users of your application to customize it using powerful object-oriented scripting. Sepi can even create classes, and work with different languages (e.g. domain-specific).

CITkit (Compiler and Interpreter ToolKIT) is a collection of Java libraries that implement the more mundane aspects of a compiler or interpreter: symbol tables, tree intermediate representations, linear intermediate representations.
