Re: [Pharo-project] System announcements and MC

by Sean P. DeNigris

Issue created: http://code.google.com/p/pharo/issues/detail?id=5652 1.4 #14438 When loading a class, I would expect a single ClassAdded announcement. Instead, we get a ClassAdded announcement, and then a ClassModifiedClassDefinition for the class (I think when the category is set), and then a ClassModifiedClassDefinition for the metaclass, but only if there are class-side instance variables. 1. Subscribe for class definition change announcements e.g. "SystemAnnouncer current on: ClassModifiedClassDefinition send: #classModified: to: self new." 2. Subscribe for class added announcements e.g. "SystemAnnouncer current on: ClassModifiedClassDefinition send: #classAdded: to: self new." 3. Load a package with MC that contains a class with a class-side instance variable and an instance-side instance variable You will see that your handler from #1 gets called twice and #2 once. -- View this message in context: http://forum.world.st/System-announcements-and-MC-tp4577351p4577660.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Sean P. DeNigris wrote > > I get notifications when MC is loading things Strange... I only get the announcements when class-side instance variables are added via MC... It seems that the reason is that MCClassDefinition>>load creates the class in two steps: 1. MCClassDefinition>>createClass takes care of all the instance side stuff, and correctly notifies of a new class 2. Metaclass>>instanceVariableNames: adds the class-side instance variable names to the class, which now already exists; so the notification is of a changed class definition -- View this message in context: http://forum.world.st/System-announcements-and-MC-tp4577351p4577658.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

For the arduino versions we have an Arduino UNO, a couple of Arduino Duemilanove with ATmega328, and an Arduino MEGA 2560. We use mostly the first two. Then we also have an Electronic Brick Starter Kit ( http://www.seeedstudio.com/depot/electronic-brick-starter-kit-p-506.html) that provides a couple of sensors and a really nice interface to plug/unplug components. And finally, we also have a couple of servos and some dc motors. Keep in mind we only use that to test stuff, we almost never build something useful out of it but it should be enough to let you started. :) Cheers, Richo > > Stef > >> > On Apr 21, 2012, at 12:00 AM, Ricardo Moran wrote: > >> > > Hi everybody (and sorry if you receive multiple copies), > >> > > >> > I would like to announce a new version of Physical Etoys, now with a > lot of new features: > >> > â¢ First of all, it's based on Etoys 5.0 so it incorporates all > the bug-fixes and new features from the Etoys release. > >> > â¢ We are now focusing on the two main hardware platforms: Arduino > and Lego Mindstorms Nxt.

Well, with Pharo 1.4, Cuis 4.0 and now this among others we're just being showered with great stuff, congratulations :) This sounds like it would work well with the ePub support I believe was mentioned for a google summer project.

[Pharo-project] System announcements and MC

by Sean P. DeNigris

I subscribed to the ClassModifiedClassDefinition announcement to be notified when an inst var is added to a class, but I get notifications when MC is loading things. This seems like a very different type of event than when one manually adds an inst var via the browser, but I don't see a way to tell which is happening based on the contextual info the announcement gives me.
