EGSL is a small interpreter which can execute Lua scripts. It includes some functions for fast and easy game development. These are image manipulation functions, functions for 2D drawing, sound and music, input via mouse, keyboard, and joypad, and some helper functions. The engine is based on SDL, SDL_gfx, and SDL_mixer, and additionally on SDL_image on Haiku-OS.
RScheme is an object-oriented, extended Scheme implementation with a compiler that targets C or (RScheme's own) bytecodes. It has features expected from a modern language: an object system, reflection, modules, namespaces, safe macros, threads, a system call interface (including sockets), separate compilation, and persistence, as well as the formal basis and power of the Scheme programming language. RScheme also features a powerful, elegant foreign code interface.
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.
Stratego/XT is a development environment for creating stand-alone transformation systems. It combines Stratego, a language for implementing transformations based on the paradigm of programmable rewriting strategies, with XT, a collection of reusable components and tools for the development of transformation systems. In general, Stratego/XT is intended for the analysis, manipulation, and generation of programs, though its features make it useful for transforming any structured documents. In practice, it has been used to build many types of transformation systems including compilers, interpreters, static analyzers, domain-specific optimizers, code generators, source code refactorers, documentation generators, and document transformers.
Alore is an object-oriented programming language with a clean syntax that resembles Python and Lua. It is optionally-typed like Google Dart. It is both a dynamic scripting language and a general-purpose language with static typing. It is aimed at most programming tasks, from short scripts to complex applications. It allows programmers to freely mix static and dynamic typing within a program. It has native threads and a very fast edit-test cycle. Programmers can always bypass type checking and run their programs immediately.
Rhope is a dynamically typed dataflow programming language that also borrows some ideas from other paradigms. Unlike mainstream programming languages, statements are not necessarily executed in the order they are written, but instead based on their dependencies. Statements that do not share dependencies run in parallel. Most operations have value semantics (i.e. modifying an object makes a copy rather than changing the original) making this parallelism safe. For managing global state, Rhope has a transaction mechanism.
X# (pronounced X-sharp) is an XML-oriented programming language designed to quickly create Web applications and services. Everything is represented as an XML tree, and instead of using functions to manipulate information or perform actions, all possible operations are done by adding, removing, or changing nodes from this tree. Since there are no functions to learn and everything is done intuitively, even inexperienced developers can create complex Web applications and services quickly.
