Denotative Objects are growing fast! - Smalltalks 2019

Presentation about updates of CuisUniversity, a Smalltalk distribution designed for teaching OOP. Particularly, we shown graphical denotative objects, a good approach for learning about objects in a more visual way.

1. Denotative Objects are growing fast! Nahuel Garbezza @ngarbezza
2. CuisUniversity
3. CuisUniversity
4. Happy birthday!
5. We’re a small community
6. Denotative Objects!
7. Tools adapted (Browser, Inspector, Debugger) to work with these objects Delegation with parent objects a-la-Self Clones and replicants: different ways of sharing behavior at object-level Smooth transition to classes DenotativeObjects
8. Denotative Object for assertions: Assert Graphical Denotative Objects (linked to a Morph object) DenotativeObjects
9. Refactorings!
10. Implemented from scratch Some refactors implemented, a lot of refactors pending to be implemented Model flexible enough to support “complex” refactors in the future. (e.g. replace if with polymorphism) Refactorings
11. Libraries!
12. Aconcagua: measures model https://github.com/hernanwilkinson/Cuis-Smalltalk-Aconcagua Chaltén: Gregorian Calendar model (based on Aconcagua) https://github.com/hernanwilkinson/Cuis-Smalltalk-Chalten Assertion helpers Libraries included
13. Didactical addons
14. Auto (or manual) restore of lost changes Stack size watcher / Recursion detection at parse-time Proper vocabulary (e.g “collaborators” instead of “inst vars”) Didactical addons
15. Demo!
16. Documentation / Examples Add more graphical objects support Managing images / Self-Upgrading More refactorings We’ll continue working on
17. Conclusions
18. Many changes on CuisUniversity also imply improving Cuis in general We have not dedicated too much time on development, but we have a decent set of features We’re constantly shaping the tools while keeping simplicity. This is helpful not just for teaching, but any kind of experiment in general There’s a lot of room for improvement. We need your help! Conclusions
19. Thank you!
