[FUNARCH’23] Functional Shell and Reusable Components for Easy GUIs

[FUNARCH’23] Functional Shell and Reusable Components for Easy GUIs D. Ben Knoble, Bogdan Popa Some object-oriented GUI toolkits tangle state management with rendering. Functional shells and observable toolkits like GUI Easy simplify and promote the creation of reusable views by analogy to functional programming. We have successfully used GUI Easy on small and large GUI projects. We report on our experience constructing and using GUI Easy and derive from that experience several architectural patterns and principles for building functional programs out of imperative systems.
