Re: [Pharo-users] subscribe on system change

by Daniel Galdames

That depends on what version of Pharo you use. In Pharo 1.4 you can use SystemChangeNotifier to do something like this: SystemChangeNotifier uniqueInstance notify: toSomeObject ofSystemChangesOfItem: #class change: #Added using: #someMethod:. then if a new class is added to the system, SystemChangeNotifier will call #someMethod: on toSomeObject, passing an Event to #someMethod:. You can browse the code on SystemChangeNotifier to see all the notification you can use, and the package "System-Change Notification" to see the events you can receive. In Pharo 2.0 you can do the same thing using SystemAnnouncer: SystemAnnouncer uniqueInstance on: ClassAdded send: #someMethod: to: toSomeObject. You can see the different announcements you can use on browsing the package "System-announcements". In this example #someMethod: will receive an announcement. -- Daniel Galdames El domingo, 14 de octubre de 2012 a las 20:14, Miguel Enrique Campusano Araya escribiÃ³: > I want to do some logic when there is a change on the system, like when a new class is loaded or when a method change.

subscribe on system change

by Miguel Enrique Campusano Araya

I want to do some logic when there is a change on the system, like when a new class is loaded or when a method change. I don't want to put this logic explicit on the methods of the system who do that. I would like to know if i could subscribe to those special events (method change, new method, changes on a class and so on) so I can do what I want outside those methods. I heard about the Announcements but I don't know if Announcements could help with this problem. Can anyone give me some highlights to do those things? Thanks!

it should work. I have many examples of such a situation and it works. Did you try to get (chef the metacello chapter) the list of packages that we will be loaded. ((ConfigurationOfCoolBrowser project version: '0.2') record: { 'CoolBrowser-Core' . 'CoolBrowser-Addons' }) loadDirective Stef On Oct 14, 2012, at 8:25 PM, Usman Bhatti wrote: > I have a configuration as follows : > > spec for: #common do: [ > "a class in package BBB inherits from a class in package AAA" > spec > package: 'AAA'; > package: 'BBB' with: [spec requires: 'AAA'] > ]. > Now, when I try to load this configuration, it fails to properly load the package BBB (there are some missing classes) with this msg: > > This package depends on the following classes: > > A class in package AAA > > You must resolve these dependencies before you will be able to load these definitions: A class in package BBB. > > It seems that there is a way to load packages in a linear order (http://code.google.com/p/metacello/wiki/FAQ#Controlling_Package_Initializat…) However, my project defaults is already set to linear and after reading this post my problem is not resolved. > > Can anyone help me how I can enforce package AAA to load before BBB? > > tx, > > usman >

about Metacello package loading order

by Usman Bhatti

I have a configuration as follows : spec for: #common do: [ "a class in package BBB inherits from a class in package AAA" spec package: 'AAA'; package: 'BBB' with: [spec requires: 'AAA'] ]. Now, when I try to load this configuration, it fails to properly load the package BBB (there are some missing classes) with this msg: *This package depends on the following classes:* * A class in package AAA* *You must resolve these dependencies before you will be able to load these definitions: A class in package BBB.* It seems that there is a way to load packages in a linear order ( http://code.google.com/p/metacello/wiki/FAQ#Controlling_Package_Initializat…) However, my project defaults is already set to linear and after reading this post my problem is not resolved. Can anyone help me how I can enforce package AAA to load before BBB? tx, usman

phil we should improve the situation. Do you have some code that we can integrate to the pharosound package and its initialization?

BaseSoundSystem soundEnabled: true just doesn't do all it should. SoundPlayer is the root of all; SoundSystems adds the background thread for multivoice play and mixing.
