Restructuring Structure Editing
summary
Claims that tile-based editing keeps programs always parseable while restoring textlike linear edits; prototypes a tiny editor called tyler that proves arbitrary range selections to token boundaries, hole insertion/removal to restore a convex tile shape, and restructuring mode that breaks tiles into shards for linear moves. Implementation works conceptually on a single-line, single-character-language and a July 2019 pilot shows users adapt quickly but stumble on ad hoc limits; ongoing work scales this toward Hazel and visibly pushdown grammars with a balanced backpack mechanism.
