AMC is a programmable compiler/preprocessor. It has a built-in programming language called CGL (Code Generation Language) that lets you add new syntactical elements to the source files that AMC processes. In addition, AMC has a module structure reminescent of the UCSD p-System compiler. AMC comes with a default package that adds a dynamic form of OOP to C.
Alice ML is a functional programming language that enriches the statically typed, closed functional world of ML with extensive support for type-safe programming of concurrent, distributed, and open systems. It also features cutting-edge constraint programming technology in the tradition of Oz/ Mozart. Alice ML is a mostly conservative extension of Standard ML.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
Brainfuck Debugger is designed to encourage the development of Brainfuck programs by providing an IDE with debugging features. One of the goals of this project is to provide an environment for people who want to experiment with the fundimental processes of computers, but not get blown away with complicated syntax issues.
C Scripting Language (CSL) is an embeddable scripting language with C syntax. A comprehensive set of libraries is included in the base package, and writing your own libraries is possible with an easy API for C programs, as well as a class interface for C++ programs. If you are looking for a compact and powerful scripting engine for your application, CSL might be the choice.
