The Complex language is an object oriented programming language intended for scripting or rapid prototyping of applications. The design goals were to have very few simple but powerful concepts and to be easy to use and easy to learn. The project provides a working interpreter along with a complete specification of the language.
SigScheme is a R5RS Scheme interpreter for embedded use. It features a small footprint (64KB in library form on the "small" configuration) like SIOD and TinyScheme, low memory consumption (2-words per cons cell), handling of multibyte characters (UTF-8, EUCs, and Shift_JIS), and more. It is mainly developed to replace the Scheme interpreter of uim.
PED is a dialogue management system that uses a probabilistic nested belief model to choose dialogue strategies. The dialogue system designer need only supply a set of plan rules to PED as a dialogue grammar with preconditions. Using this grammar, PED constructs game trees (like the one below) to represent the outcomes of the dialogue, so that a dialogue strategy can be chosen for the current turn in the dialogue. PED automatically maintains a belief model by a belief revision process that uses the observed acts in the dialogue. The game tree is evaluated in the context of this belief model. PED is efficient because it uses probabilistic estimates of belief rather than a plain logical belief model.
Funky is a tiny, embeddable programming language with almost unlimited extending capabilities. It presents itself as a single class that contains the entire interpreter. Two versions of this class exist: Funky::Funky, a floating-point version, and Funky::Groovy, an integer version. You can install your own functions in the language as long as your functions take a vector of the built-in type of the interpreter and return an instance of that built-in type (or a vector of those). Funky is a functional programming language. As such, it treats everything as functions, and those functions handle only one type: double in the case of Funky::Funky, or int in the case of Funky::Groovy.
