Hi Andy, You can also just hook into GTSpotter. It already provides the infrastructure for handling parallel search and lets you focus only on specifying the search logic.

I would be you I would - prototype a hierarchy of classes whose instances have a kind of patterns to know if they should be kick in - at the end of each line, I would send the line to a list of such "agent" and react - then only then, I would consider to fork the behavior of the agents. why? because when you can avoid concurrency this is simpler :) >> Thanks, that sounds like a very good way forward.

Re: [Pharo-users] Question about Morphic in Pharo 4

by stepharo

Hi daniel, I do not have the time to go too much into the details. Now orginal Morphic made mistake (global coordinates is one). What is important for us: - cleaning the current version (we made a lot of progress with FrameLayout and others) - untangling polymorph - migrating to athens may be better to build on Bloc but we will see (note that Bloc is fully vectorial now since a couple of days) - supporting themes correctly - identifying and improving widgets - UIBuilder theme with all the widgets creation in this class is a bad pattern. Each widget should have its API in its class! - cleaning Spec (we should handle the announcement plague) - in parallel prepare the future with Bloc. - I'm currently reading code and adding new class comments - preparing a tutorial - checking the widget we built Stef
