GRASP: A GRAphical Scheme Programming environment
summary
Android app GRASP is a graphical S-expression editor implemented in Java and built on-device via Termux; it loads/saves files, renders code as movable boxed expressions, and currently supports atoms and proper lists only with strings, comments and improper lists planned. Editing uses gestures: draw lines to split, pinch/zoom navigation, drag/drop, double-tap to copy, fling-to-discard and a splice gesture called pulling the rug. Backend evaluator is not yet implemented; repository contains staged builds and build scripts.
