Creating a Class in a Temporary Environment
by Sean P. DeNigris Sept. 5, 2015

Sept. 5, 2015

I used to have creatingAClassInATemporaryNamespace | testingEnvironment morph | testingEnvironment := SystemDictionary new. ClassBuilder new name: #AClassForTesting inEnvironment: testingEnvironment subclassOf: Object type: Object typeOfClass instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'TemporaryTesting'. How do I do this with Slots? I tried: creatingAClassInATemporaryNamespace | testingEnvironment morph | testingEnvironment := SystemDictionary new. PharoClassInstaller make: [ :builder | builder superclass: Object; name: #AClassForTesting; environment: testingEnvironment; category: 'TemporaryTesting' ]. but got "key #SystemOrganization not found in SystemDictionary". ----- Cheers, Sean -- View this message in context: http://forum.world.st/Creating-a-Class-in-a-Temporary-Environment-tp4825963… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Becoming good at VM development
by Ichiseki Sept. 5, 2015

Sept. 5, 2015

Hi hello to everyone & everybody I am interesting in going deeply into VM design, development, optimization, etc. I know a lot of Haskell, a good amount of C and some languages that use VM like Python, Lua and Pharo of course. What would be a road map (books, articles, code to read) to understand deeply and in detail the Pharo VM, the inter operation between the VM and the image. I know this could take a lot of time but I'm committed to invest that time. Please help me as literature on these topics is very scarce... Thank SO SO much in advacne ichiro -- View this message in context: http://forum.world.st/Becoming-good-at-VM-development-tp4846536.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

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?

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
