AsciiArtWidget creates and handles a widget with bindings appropriate for easy creation of ascii art. Basically it is a text widget filled with spaces and newlines, and character inserts replace a space, and backspace/delete replace characters with spaces so that the right hand side of the image is always in the right spot. Includes a mouse drag painting binding, and block sleection/delete, as well as a data loading and squaring system.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
ClassyTcl is a dynamically loadable object system for Tcl. Both a Tcl-only and a C implementation are available. It also doesn't require patches to the Tcl core, which makes installation and maintenence easier. Performance is quite adequate. The C version is gives extra speed, and makes it possible to implement some methods in C. In contrast to other object systems for Tcl, it is not modeled after the object system designed for a completely different language, such as C. The system is simple but flexible. Classes and objects are dynamic, and can easily be queried, changed, and debugged at runtime.
Clig uses a simple description file to create C-code to interprete the typical *NIX command line as well as an up-to-date usage-message and a manual page skeleton. It supports Flag, String, Int, Long, Float and Double types, with ranges, defaults, and more. The generated C-Code is ANSI but has been reported to work with C++. It is self contained code which does not depend on any library other than libc. Included is a TCL-only TCL-package to instrument your TCL scripts the same way as your C-programs.
The Event monitor project is an approach to network management based on message passing between manager and managed nodes. It's based on a client/server platform, where the server is the manager node, and all clients are managed nodes. This tool is under development, but has lots of features implemented, like a graphical console, message passing layer, one disk monitor and clients for sending messages (both API and binary forms are provided).
Memchan is an extension library to the script language Tcl, as created by John Ousterhout. It provides two new channel types for in-memory channels and the appropriate commands for their creation. They are useful to transfer large amounts of data between procedures or interpreters, and additionally provide an easy interface to on-the-fly generation of code too. No need to set or append to a string, just do a simple puts.
