where to find the ia32/i386 runtime libraries
by albert Aug. 31, 2015

Aug. 31, 2015

Dear Sirs: I have: opensuse 13.2 x86_64, and glibc 2.19. So, I downloaded: Default GNU/Linux Pharo4.0-linux.zip. After extracting zip, README.txt says: ~ Just install the ia32/i386 runtime libraries and you should be fine. However, there are no files with such names among the extracted files. How to proceed installing the runtime libraries? In advance, thank you. By the way, opening pharo tells me: ~ You can learn pharo by highlighting the next line and selecting [Do it] from the context menu:" PharoTutorial go. Obviously, nothing happens when following these instructions -- the vm isn't there. When closing the pharo environment window, I get asked to save any changes. At least, I get a dialog widget. Thanks, Albert

Pharo 4.0 -- Inspecting a recursive data structure is slow
by H. Hirzel Aug. 29, 2015

Aug. 29, 2015

Hello I have realized that inspecting a recursive data structure is very slow in Pharo 4.0 A test case: | myDict | myDict := Dictionary new. myDict at: #hello put: 'hello'. myDict at: #recurHello put: myDict. myDict inspect It takes a long time for the inspector to come up. And the image freezes later on if you continue. The problem is with the inspector because if I do | myDict | myDict := Dictionary new. myDict at: #hello put: 'hello'. myDict at: #recurHello put: myDict. 3 + 4 inspect it comes up instantly. As a comparison I attach the Cuis ** test result. The inspector comes up instantly and the image does not have any problems. What are the workarounds in Pharo 4.0? - Setting a time out somewhere? - Disabling certain functions? - Loading a simpler inspector? Regards Hannes ** current build 2463.image https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev

Multi desktops inside Pharo!
by Torsten Bergmann Aug. 28, 2015

Julien Delplanque wrote: >I created a small utility that make possible to have multi desktops: >https://github.com/juliendelplanque/desktopsmanager. Your code works for me in Pharo 5, havent tried in Pharo 4. Unfortunately it does only work for Pharo "windows" but not general morphs. If you evaluate ElipseMorph new openInWorld and hit CTRL+SHIFT+J you will see that the morph stays on the desktop. So your goodie is a "window switcher" and not a "desktop switcher". I guess it would be better if you would really switch the WorldMorph instance referenced by the global "World" variable. There already was a solutions once discussed/contributed with code here http://forum.world.st/Multiple-Worlds-for-Pharo-stable-td3233552.html http://seandenigris.com/blog/?p=767 I think it got lost in the old bugtracker. Maybe Sean (who wrote it) can help here, update the code and merge with yours. Ideally such a "Switch desktop" possibility would be part of the standard Pharo 5 image including a small preview of the whole desktop similar to what usual operating system window manager do and the possibility to provide different backgrounds to the desktops. Thanks Torsten

Slow World Menu opening
by Alexandre Bergel Aug. 26, 2015

Aug. 26, 2015

Hi! When I open the world menu, the mouse cursor is intensively blinking, and opening the menu is _very slow_. This bugs has been around for a couple of weeks already. Am I the only one to see it? I have checked the cause, and apparently the problem disappear by removing the use of âCursor read showWhile:â. The following method: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. Cursor read showWhile: [ form := reader nextImage. reader close ]. ^ form -=-=-=-=-=-=-=-=-= May be rewritten as: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. form := reader nextImage. reader close. ^ form -=-=-=-=-=-=-=-=-= However, changing the cursor has been around for quite a long time. It is strange that the slow menu is surfacing only now. Any idea why?

How can an object have its "self" and "name" instance variables nil after being instantiated?
by Julien Delplanque Aug. 25, 2015

Aug. 25, 2015

Hi, I have an object that override KMCategory and that is initialized and added to "KmRepository default" using #postLoadDoIt: message in BaselineOf after the package is loaded in an image. But once it is loaded I have huge problems with keyboards entries, they do not work any more, I get an exception each time I press a key. If I inspect the Singleton class variable of my category object I can see it contains an instance of my object that have its "self" variable nil and its "name" variable nil. Others variables look fine. How is it possible? I can remove my custom KMCategory by copy/paste code from sublime text to Pharo and left click/do it and then everything is fine with my keyboard: no more exception and it behave correctly. Thanks in advance, Julien
