Re: [Pharo-project] Let's change DamageRecorder>>new

no, I think it wont change the behavior, the change would just fix a bad style of coding.

[Pharo-project] Split sound package -> Cog not loading in last 1.4
by Mariano Martinez Peck Jan. 25, 2012

Jan. 25, 2012

Hi guys. Cog is not loading anymore in 1.4 because of some classes depending on Project from the 'Sound' package found in PharoSound repo in SS. At the beginning I thought to create a separate package "SoundVMSupport" and put there the needed classes, but I discover that there are a lot which are needed. And moreover, all of those needed classes are in the category Sound-Synthesis. The classes problematic (regarding Project and morphs) are in the other package Sound-Scores. I have just tried and split the Sound package in two: SoundScores and SoundSynthesis. Then I changed ConfigurationOfCog to load SoundSynthesis rather than Sound. That works and I can now build the VM without problems. I think that the split makes sense even without of the need of Cog. Do you agree? If true, I can commit everything. One of the things I am not sure is how to make sure Sound package is not used anymore. All I can do is: a) Put a comment in squeaksource page saying that the packages are now SoundScores and SoundSynthesis. b) Create a new baseline and version of ConfigurationOfPharoSound which reflecs this change c) Commit a version of everything empty (no single class) to the package Sound. Which ones of these should I do ? Thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] [Event related] Character vs Keys
by Guillermo Polito Jan. 24, 2012

Jan. 24, 2012

Hi! While playing (again) to add Function keys support, reading documentation of how keyboard handling works on our vm and other platforms: .Net: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydow… Javascript: http://www.quirksmode.org/js/keys.html And a quick explanation of Igor of how our vm works: http://lists.squeakfoundation.org/pipermail/vm-dev/2011-November/009661.html What puzzles me is some of the following: - Keypress event should only be raised to send keystrokes having a character representation. - but some keystrokes with no character representation are taken as keypresses! (arrowup, arrowdown, esc...) (and so, used to handle events instead of doing it on keydown) - the strokes above should be only raised in keydowns IMHO. - more on, we have in Character class representations for those *non characters* :P which is funny because they are not characters. And everything works, and fits in a kind of strange way :). Now, rearranging this to follow those conventions means: - reify Keys (vs Characters). So we can model modifier keys, function keys, arrow keys, independent from Characters. - Keys (non-characters) should only be raised as single events on keydown. - and the worse part is to fix all the hardcoded shortcuts messed everywhere in the image. Any thoughts on this? Thanks! Guille

[Pharo-project] Exception chapter PBE2
by Norbert Hartl Jan. 24, 2012

Jan. 24, 2012

I've read the exception chapter of the new PBE. And I really enjoyed reading it. I find it easy to understand and well-balanced between how-to-use and how-it-works. Great work! Norbert P.S.: I thought I've found a typo where a message sentTo: is used. But then I discovered there is indeed a message called sentTo: Unfortunately I didn't get the difference to sendTo: :)

[Pharo-project] ZipWriteStream error when closing it twice. Normal?
by Mariano Martinez Peck Jan. 24, 2012

Jan. 24, 2012

Hi guys. I found that GZipWriteStream throws an error when closing it twice. Example: | aStream zipStream | aStream := ByteArray new writeStream binary. zipStream := GZipWriteStream on: aStream. zipStream close. zipStream close. All the streams I know do not throw an error in that case. And moreoever, it gets things complicated when using #on:do:. For example: FileStream forceNewFileNamed: testFileName do: [ :stream | GZipWriteStream on: stream binary do: [ :gzipStream | FLSerializer newDefault serialize: anObject on: gzipStream ] ]. In thise case, FLSerializer closes the stream at the end. No matter whether Fuel should do that or not, the thing is that in this I have the mentioned problem. So...my question is, is this a bug? if it is, do you have a better idea that changing #close to this: ZipWriteStream >> close literals isNil ifTrue: [ "#initialize sets this instVar to a specific value. #release puts it in nil, and #release is called from #flushBlock: which is called from #close:. Therefore, if it is nil, it means the stream has already been closed. If we try to close it twice, #flushBlock will throw an error because its instance variables are with nil" ^ self] self deflateBlock. self flushBlock: true. encoder close. -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] Fwd: [squeak-dev] ANN: OpenGL + NativeBoost + Mac ==> success

Check out the most recent mail to this mailing list by Bert Freudenberg, were he explains the inner workings of the Ballon3D plugin, to achieve what you propose. The other means would be to change the VM, and bypass completely the bitmapped "Display", and provide Events+a windowed OpenGL context ,to were we can draw within the image. Check out recent emails from myself in the list,the thread titled "decoupling the vm: UI and interpretation".
