Re: [Pharo-project] OB package browser don't detects newpackages/updates a package list

...

Of course we could always update whenever there is a change in the system, but this would lead to a huge performance penalty, particular when loading or fileing in code, so I didn't change that.

I think that is fairly simple:

SystemChangeNotifier uniqueInstance notify: self "browser" ofSystemChangesOfItem: #class change: #Recategorize using: #someClassChanged:.

In #someClassChanged: post a deferred message to update browser cache, so it will be handled just after file-in will be complete.

Actually this is what we are doing now, we defer the update until World steps in. See OBCodeBrowser #event:, #noteChanges and #stepAt:in:. Or about what kind of deferring mechanism are you thinking? David
