Recoverying a crashed Moose image/Pharo5

by Hilaire

Hello, I have a Moose 6.0 image with several Playgrounds. Since this morning, exactly when I want to make a demo[1], it crashes immediately. I remember yesterday I got an error when saving, Pharo said something like 'This error should not happen'. The OS windows open then close almost immediately (dump included). Could it be related to Athens or FreeType plugin access? The image went about 113MB. The used VM works fine with a fresh Moose6.0 image. Btw, the http://www.moosetechnology.org/ is down right now. I would like to recover the script codes in the playgrounds, is there a way to access it? Thanks Hilaire [1] Hopefully I can demo with a fresh image of Moose -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

Re: [Pharo-users] Is RBClassNotReferencedRule ~200x slower in Pharo 4 vs Pharo 3 ?

by Paul DeBruicker

Hi Stef, The slowdown is dependent upon the # of classes in the package. If you use Fuel then you should see a slowdown of 20x. I just have a lot of classes in this package. The source of the slowdown is in the changes to RBSmallLintChecker>>#checkClass: and RBClassNotReferencedRule>>#checkClass: . The old versions use the linter to check if the literal is used anywhere and the new one uses #allCallsOn. Hope this helps Paul -- View this message in context: http://forum.world.st/Is-RBClassNotReferencedRule-200x-slower-in-Pharo-4-vs… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Script of the day

by Alexandre Bergel

Hi! Just to share a couple of experiment. I have tried the following in a playground: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= b := RTMondrian new. b shape rectangle if: [ :aFile | aFile path basename beginsWith: '.' ] color: Color red. b nodes: FileLocator documents allChildren. b edges connectFrom: #parent. b normalizer normalizeSize: #size using: #sqrt. b layout tree. b -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= It shows a tree of the file system. Thanks to GT, simply clicking on a file may show you the content and other things. You can also use the cluster layout: I have tried this on OS X, since the pointed folder is ~/Documents.

There is no documentation for now but I'm updating it. I'll include the presentation generation to the Pillar chapter on the 'Pharo for The Enterprise' Book this week or next week. For now you can have a look at the Pharo Mooc: https://github.com/SquareBracketAssociates/PharoMooc There is a Slide folder and a compile-slide script.
