Hi, There is a difference in performance. The Announcement is slower (about 2-3x slower). However, for 1M events the difference is measured in a 200-400ms, which is very small. The benefit of using Announcement is that we can reuse the tooling around Announcement, such as blogging and debugging. Still, the way it is used in Bloc is different from the typical usage in that Bloc registers to all Events (which are Announcements) and then dispatches through them to specific Element method (like BlEventListener>>clickEvent:). Still the cool thing is that you also can still register from the outside to a specific event using a normal when:do:. We will write a piece of doc about it. Cheers, Tudor

Hi,
Here is an update of the work on Bloc and GT. As always, please do let us know what you think.
Bloc: - Eventing saw a deep overhaul. They are now dispatched using the Announcements engine. The previous mechanism is still in place in order to help people compare the impact. In the process, we also cleaned the propagation of events, and we made them debuggable through inspector extensions: https://twitter.com/feenkcom/status/955086133519618048 https://twitter.com/feenkcom/status/946482609680539649 - Embedding Bloc elements in Morphic is even easier now: https://twitter.com/feenkcom/status/946676667002556416 - We continued the work towards an interactive creation of a graphical scene: https://twitter.com/feenkcom/status/948492946541858816 - Theme experiment
GT: - The documentation of Mondrian is available when you download the code and can be viewed using GT Documenter: https://twitter.com/feenkcom/status/939394586115563520 - The Mondrian extensions of BlElement are now extracted in a more general package that enables Bloc elements to be used in graph scenes.
Have fun, The feenk team

So you mean each event <1ms difference? btw, what is the biggest usage of events? I guess mouse movements? How many such events typically in 1 second of movement? How is performance on StackInterpreter VM? I guess we should keep that performant for platforms lacking JIT like iPads, etc...
The benefit of using Announcement is that we can reuse the tooling around Announcement, such as blogging and debugging.
This looks really useful. Can you describe the difference between the red and blue lines in the picture of the first link? cheers -ben

It depends on the scene. We are still looking into how to evaluate this. Thatâs why we still have both implementations around.
The benefit of using Announcement is that we can reuse the tooling around Announcement, such as blogging and debugging.
This looks really useful. Can you describe the difference between the red and blue lines in the picture of the first link?
Each event goes through two passes, like in JavaScript: - The first is called âcapturingâ (or filtering) and goes from the root to the leaf. This is to allow a parent to prevent a child to react to an event. - The second one is called âbubblingâ (or handling) and goes from the leaf to the root. This is to find the most specific element to handle the event. Cheers, Tudor
