Pixane is an image processing library for Tcl that allows the scripting of all kind of image transformations. It supports reading from and writing to a large set of file formats (JPEG, PNG, GIF, BMP, WBMP, etc) and provides anti-aliased text rendering and a set of built-in fonts. It doesn't requires Tk, so it can be used to easily generate images dynamically from CGI. Binaries are provided for many platforms as dynamic libraries with no external dependencies for easy deployment. It is also a core component of the eTcl distribution.
EasyRunner is a program launcher that is easy to operate. You add buttons simply by clicking in an empty place on the main window grid and defining its associated command. You can also have indefinite levels of sub-menus, each with their own buttons and hotkeys. If wanted, you may lock the user interface with a password to keep the end user from changing it. EasyRunner is distributed as a platform-independent starkit.
The BID software was designed to apply business rules to your email traffic. Business information can come from business applications, monitoring applications, or normal users requesting or providing data. The goal of the BID tool is to automate the dispatching of this information and to join a business-case with a responsible receiver. A receiver can be a human being or another BID server customized for a special business-case. The BID server was designed as a generic server using plugins to serve specific business-rules.
The Model Railroad System is a software package that can help you run your railroad. It allows you to operate your layout, from running trains to working your signals and switches. It has support for a network of Bruce Chubb CMR/I USIC, SUSIC, and/or SMINI nodes, and/or a network of Lenz's XPressNet DCC nodes. Azatrax USB-connected Model Railroad Detectors are supported. Software to create switch lists for freight car forwarding and create timetables for your railroad are included. There is software to help with photographing your trains, and to compute the correct value for those pesky dropping resistors for LEDs and/or incandescent lamps.
expect-lite is an quick and easy command line automation tool. Written in expect, it is designed to directly map an interactive terminal session into an automation script. expect-lite scripts use special character(s) at the beginning of each line to indicate the action. Basic expect-lite scripts can be created by simply cutting and pasting text from a terminal window into a script, and adding '>' '<' characters. No knowledge of expect is required. Expect-lite is targeted at the verification testing environment, and will produce a Pass/Fail result at the end of the script. However, its use is not limited to this environment. It includes a powerful debugger with breakpoints, step/skip, and the ability to copy/paste expect-lite lines right into a running script.
Poet (Prototype Object Extension for Tcl) is an OOP extension for Tcl/Tk featuring prototype-based inheritance, constraints, and persistence. It includes Poetics (Poet Integrated Construction Set), a set of tools for end-user inspection and modification of a running Poet application. The current Poetics tools are an object browser and a syntax-highlighting code editor. Poet is available wrapped as a starkit that can be used to load Poet into Tcl or standalone to demo and install Poet.
Trowser is a browser for large line-oriented text files (such as debug traces). It's meant as an alternative to "less". Compared to less, trowser adds color highlighting, a persistent search history, graphical bookmarking, separate search result windows, and flexible skipping of input from pipes to STDIN. Trowser has a graphical interface, but is designed to allow browsing via the keyboard at least to the same extent as less. Key bindings and the cursor positioning concept are derived from vim.
AudioSpace calculates the amount of storage required by an audio recording of a given duration, for different sampling rates, resolutions, and numbers of channels. The calculation may be made for uncompressed audio data or for several types of compression. A variety of units may be selected for reporting the result. The calculation may also be inverted to determine the maximum duration of audio that will fit into the available storage.
Micropolis is a city simulation game engine based on the original classic SimCity source code. Micropolis is based on the Tcl/Tk version of SimCity. It consists of the micropolis module, which is the engine recast as a C++ class; the cellengine module, which is a cellular automata machine engine; and the tileengine module, which is a Cairo based tile renderer. It is intended to be used with the OLPC's Sugar user interface environment, but layered so the core code is useful in other contexts.
