[Pharo-project] R.I.P. SystemChangeNotifier
by Esteban Lorenzano Aug. 7, 2012

Aug. 7, 2012

Hi, Today we finally finish the removal of SystemChangeNotifier. This is a big step forward to unify all system events into announcements. Current notification center is named "SystemAnnouncer" and all events has been reified into more meaningful announcements... This operation was really hard because is like changing the heart of a living person :) For 99.99% of users, this will be absolute transparent, but there are some cases where maybe some problems emerge. Please, take this into account to migrate your code soon. Don't wait until is to late! Cheers, Esteban

[Pharo-project] Jenkins: SCM polling activity overload
by Sean P. DeNigris Aug. 7, 2012

Aug. 7, 2012

See https://ci.lille.inria.fr/pharo/descriptor/hudson.triggers.SCMTrigger/ : There are more SCM polling activities scheduled than handled, so the threads are not keeping up with the demands. Check if your polling is hanging, and/or increase the number of threads if necessary. The following polling activities are currently in progress: Project â Running for Scripts-download 18 hr -- View this message in context: http://forum.world.st/Jenkins-SCM-polling-activity-overload-tp4643404.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Playing with a declarative startup/shutdown subscription mechanism
by Guillermo Polito Aug. 6, 2012

Aug. 6, 2012

Hi! Last days I was playing to replace the image startup/shutdown mechanism via a pragma subscription because I was pissed off with how difficult is to integrate the change of a new startup in the system. The idea is: - reduce the mess on subscription/unsubscription, initialization, etc - reduce dependencies of external packages in core packages. This way, if you want to subscribe a class side method to be executed on startup, you annotate it: SomeClass>>startUp: resuming <systemStartup: #application> self blahblah. SomeClass>>startUp: quitting <systemShutdown: #kernel> self blahblah. Now, instead of an order in classes startup, I played with the idea of having run levels (which I named #kernel, #application and #user because I was not inspired :P). Then I replaced the whole system startup and It's working... The code is very simple, you can have a look at the category *System-Tasks*which can be downloaded from: MCGemstoneRepository location: 'http://ss3.gemstone.com/ss/PharoTaskForces' user: '' password: '' SLICE-Issue-666-Playing-With-startup-GuillermoPolito.2 Be careful, that package contains the startup code + the replacement of the old startup by the new one :). Now, I'd like to have some feedback, u like it? u buy it? which should be the names for the run levels? how many run levels should we have? :P Cheers, Guille

[Pharo-project] New feature in Nautilus
by Benjamin Aug. 6, 2012

Aug. 6, 2012

Hello guys :) I just wanted to show you the new feature I just finished to implement into Nautilus: the multi methods edition http://dl.dropbox.com/u/24369478/MultiMethods.mov The video is quite short (1min) but it will be integrated soon in the image so ;) Some explanation: - now you can "pin" a text area, it will "freeze" the context, so you can edit it and save it without problems - you can have a many as wanted - the scroll pane is a bit clever to always keep the maximum size for the current edition (but there are splitters, so you can set it as you want) - you can "unpin" a text area, and it closes it (to add: check if there are pending changes) - the glitch about the color is the video has been fixed already (but I am too lazy to make another video ^^) - the frozen area get a help text which tells the method the source code comes from - the corresponding button have the same help text - clicking on the button jump to the method I hope you will enjoy it, and as usual if you have cool ideas, let me know ;) Ben

[Pharo-project] using color tables with forms and bitblt?
by Lawson English Aug. 6, 2012

Aug. 6, 2012

OK, I'm such a noob here, that I'm not quite sure how to ask my question... I have a "dwell file" -an array of values generated by a Mandelbrot Set application, one per pixel, with arbitrary values between 1 and xxxxxxxxxxx (currently less than 2 billion, and right now far less than 1,000,000)- and I would like to use them, suitably tweaked, as indices into a ColorMap. The ColorMap need not have 1,000,000 entries. No-one can see that many color differences in a Mandelbrot set anyway. I can generate an array of Color (ColorArray?) but I'm not sure how to use them to create the ColorMap, and I'm not sure how to use the ColorMap to speedily change what is drawn in the first place. Right now, I'm creating a color dictionary and drawing via: 1 to: 800 do: [:y| 1 to: 800 do: [:x| |i| i := x+ ((y-1) *800). aForm colorAt: x@y put:( myDictColors at: (myArray at: i )).] ]. where myDictColors is a dictionary whose keys are the dwells listed in the dwell array file and whose values are Color objects from my array of colors. Drawing the above takes about 1.5 seconds, which is a bit slow. I'd like realtime-ish updating as I play with colors in the palette. Can this be done, at least up to the 4096 color limit that BitBlt has for ColorMaps? If so, how? I've been trying to figure out the various classes and I'm stumped.

[Pharo-project] Spec 1.1 in Pharo 1.4
