Thyrd is an experimental, reflective, visual programming language and environment. In Thyrd, both data and code are stored in cells situated in nested two-dimensional grids. All operations the user can perform to edit the structure are implemented as operators in the Thyrd language, thus a Thyrd program can inspect and modify itself or other programs in the same space. Thyrd belongs to the Forth family of languages. It most resembles Joy in that it uses quotation and combinators to implement iteration and recursion.
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.
ColorExplorer is a tool for exploring the color space and finding out how colors, color names, and numerical color specifications are related. The user can specify a color by selecting its name from a list of color names, by adjusting sliders that control the mixture of red, green, and blue, by entering a numerical color specification, by copying it from the history list or elsewhere on the display, or by requesting a random color. The numerical specification of the current color and an example of that color are shown in a pair of adjacent boxes. The color name list may be searched by entering a regular expression or by requesting the closest match to the current color.
The QConsole class is a custom widget that implements a basic console, written in C++ and relying on Qt. It implements several features and is intended to be inherited from in order to have a "real" console for a specific scripting language, shell, etc. Example implementations for TCL and Python are included.
