Denicek: Computational Substrate for Document-Oriented End-User Programming
summary
Denicek claims a reusable computational substrate that models programs as edit histories and exposes three concrete operations: edit application, merge + conflict resolution, and history-based invalidation. The team implements a web-based environment with six formative examples and a data-science notebook that demonstrates collaborative editing (list→table merge), programming-by-demonstration macros (recorded edits bound to a button), and fine-grained invalidation via a structure editor. All three demos run on the same substrate and successfully validate the approach.
