[Pharo-project] Block questions

I'm taking some times to go back the block closure chapter and I was wondering how I can get access to block temporaries [ |a | a :=2. a] for example I tried [ |a | a :=2. a] outerContext contextForLocalVariables tempAt: 1 and variations but none worked. Stef

[Pharo-project] Pharo 1.4 DosFileDirectory>>preferencesRootPath broken

by Hilaire Fernandes

Can windows user confirm? I don't have a Windows OS, only Wine. http://code.google.com/p/pharo/issues/detail?id=5596 It is seems related to saved preferences. Hilaire -- Dr. Geo -- http://www.drgeo.eu

[Pharo-project] Broken Pharo 1.4 and windows VM

by Hilaire Fernandes

I took the Pharo 1.3 one-click package from Pharo-project then I replaced the image with a Pharo 1.4 image. It looks like the code from DosFileDirectory>>preferencesRootPath is broken or the the used VM does not return the expected value (Smalltalk vm getSystemAttribute: 1002) I tested with the COG VM for Windows from Pharo web site, the problem is the same. Fix may be easy but I don't know exactly the extent of the problem. I have tested under Wine as I don't have windows. Hilaire preferencesRootPath | list rootPath osMajorVer | "First try to adhere to hardcoded Microsoft conventions - though we really should be reading environment variables since %SYSTEMDRIVE% might not be C: " "Windows OS Version numbers from http://msdn.microsoft.com/en-us/library/windows/desktop/ms724832%28v=vs.85%…" osMajorVer := Smalltalk os osVersion first. osMajorVer = $5 ifTrue: [ rootPath := 'C:\Documents and Settings\All Users\Pharo\']. osMajorVer = $6 ifTrue: [ rootPath := 'C:\ProgramData\Pharo\']. -- Dr. Geo -- http://www.drgeo.eu

Hi Ben, Your mail requires a bit more attention span than I can afford right now, and I do not quite understand what the issue actually is. But, this does not mean it went unnoticed :).
