The Whim Window Manager Steve Redler IV, George Peter Staplin Whim is a window manager written for the X11 graphical windowing system that has its primary logic and functionality coded in tcl/tk. It uses two newly developed c extensions to give tcl/tk the fine control needed to properly implement a window manager, with Whim being not just a proof of concept, but instead a full function, comfortable and intuitive interface to X11 applications. The technical design goals of Whim include: being deployed as a starkit, and to optionally use the tile extension for enhanced window titlebar theming. Most importantly, Whim enables full customization at the scripting level, eliminating the need to work with the X11 c api directly.
