Monster script (or just Monster) is an advanced scripting language made specifically for game development. The language features many new and powerful features, while still aiming first and foremost at increasing productivity and actual usability. The language is especially designed to facilitate game modding and user-generated content and scripts. It is highly object oriented, type safe, bytecode-compiled, and is easily embedded into existing game engines.
MiniD is a scripting language influenced by Lua, D, Io, Python, and other languages. It has a C-style syntax, is dynamically typed, and is designed to be easily embedded within and extended by a larger host application. It is written in (and is designed to be used from) the D programming language. It can also be used as a standalone language. Some external libraries are currently under development, including bindings to SDL, OpenGL, and libpcre.
The Open-Transactions project is a collaborative effort to develop a robust, commercial-grade, fully-featured, free-software toolkit implementing a full-strength financial cryptography library, API, CLI, and prototype server. Open-Transactions democratizes financial and monetary actions. You can use it for issuing currencies/stock, paying dividends, creating asset accounts, sending/receiving digital cash, writing/depositing cheques, cashier's cheques, creating basket currencies, trading on markets, scripting custom agreements, recurring payments, escrow, etc. Strong crypto is used. Balances are unchangeable (even by a malicious server). Receipts are destructible and redundant. The transactions are unforgeable. The cash is untraceable. The cheques are non-repudiable.
D:GameVFS is a minimalist virtual filesystem library for the D programming language oriented at game developers. It provides an easy-to-use API for filesystem-independent file/directory manipulation. It supports basic VFS functionality. Files and directories can be created, read, and written, but not deleted. There are no security features (e.g., D:GameVFS can't handle a situation in which a file it's working with is deleted outside the program).
