def Gribber = (Grace + Gibber)

Jones, Timothy; Noble, James

Grace is a new object-oriented education programming language that we are designing. One of the Grace implementations, Hopper, is an interpreter that runs on top of JavaScript. Gibber is series of libraries that support real-time audio processing, and also a simple livecoding interactive development environment, also on top of JavaScript. In this demonstration, we will present Gribber, a web-based IDE that incorporates the Hopper interpreter into the Gibber IDE, and so gives Grace live access to the Gibber audio libraries. Because of Hopper’s continuation-passing design, Gribber programs can appear multi-threaded, apparently running one or more loops in parallel, each pseudo-thread generating sound and graphics in simultaneously. We will demonstrate how Gribber can be used for BALSA-style algorithm animation, and Sorting Out Sorting style algorithm races.
