Bigloo is an implementation of the Scheme programming language. It relies on an optimizing compiler from Scheme to C. Bigloo enables connections between Scheme code and C code. It proposes many extensions to Scheme such as a regular parser compiler, an lalr parser compiler, pattern matching, an object layer, etc.
travtrack is a tool to help a Traveller(tm) referee keep track of essential data for a game. Already implemented are galaxies, sectors, subsectors, systems, stars, planets, belt and moons. Yet to be implemented are trade routes, ships, characters, and all the rest. These will take some time, but should not be too complex. It currently uses the GURPS Traveller:First In rules for system generation, but a subproject is under way to add Classic Traveller generation and output. travlib is a collection of C routines that should make writing a Traveller application easier. A guile interface to the data representation functions is provided.
libtour is a generic tournament processing library. The rules, participants, schedule, and results of a sporting tournament can be defined in the Scheme programming language and given to the library as input. A CLI application is provided as a reference client implementation. See http://freshmeat.net/projects/qtour/ for a Qt-based client.
The mother modular generic compiler is designed to compile arbitrary computer languages to arbitrary assembler code. the desired language and assembler is specified as tables, so there is no need to generate something like a "cross compiler". Further, mother is modular, as it is made up of a set of separate tools which are used in the very Unix fashion of calling them in a pipe.
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.
TextureOps is a set of plug-ins for the GIMP related to texture. Compositing a feathered layer on top of another layer slightly reduces the contrast in the the feathered region, noticably modifying the texture. TextureOps contains a "Sharpen Feathering" plug-in to counteract this effect. Also in TextureOps is a modified version of the standard "Make Seamless" plug-in that produces a more uniform result, based on similar principals. Finally, TextureOps provides a simple script for synthesizing a tilable texture of arbitrary size from a sample using the Sharpen Feathering plug-in.
vrml-scm is a VRML (Virtual Reality Modelling Language) parser written in scheme. The parser strictly conforms to the VRML 1.0 standard. It implements only parsing and syntactic checking. There is no semantic checking of the data. The scheme module is self-contained, and has been tested in guile and Bigloo.
