RAM-efficient alternative to ZnMultiPartFormDataEntity
by mikefilonov July 1, 2015

July 1, 2015

Hello, I'm searching for an alternative implementation of ZnMultiPartFormDataEntity which dumps it's parts to Filesystem as files saving RAM. Is there such an addon or it should be developed? Thanks, Mike -- View this message in context: http://forum.world.st/RAM-efficient-alternative-to-ZnMultiPartFormDataEntit… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

by Serge Stinckwich July 1, 2015

Hi Ronie, since we switch here from OS X 10.10.2 to 10.10.3, your OpenCL framework doesn't not work anymore ... We crash Pharo everytime we try to use GPU. This is an except of the crash log: Process: Pharo [21039] Path: /Applications/Pharo.app/Contents/MacOS/Pharo Identifier: org.pharo.Pharo Version: Pharo 0.2.7-2015.04.20 (21.0) Code Type: X86 (Native) Parent Process: ???

Hi, is there any image (as in picture) processing library in the likes of Python's PIL(http://effbot.org/imagingbook/image.htm), or even (highly unlikely) something like OpenCV (http://opencv.org/)? Thanks, Peter

Chess Game / UpdatingStringMorph
by Volkert June 30, 2015

June 30, 2015

I am trying to load the old chess game from Squeak [1] into Pharo 4.0. The game depends on the class "UpdatingStringMorph", but this is not part of Pharo. What happened to it? Was it renamed? BW, Volkert [1] http://map.squeak.org/package/cb19b6f1-e371-47b2-b814-4bad079d0fbc

Glamour: opening paths in tree with filters
by Usman Bhatti June 30, 2015

June 30, 2015

Hi, I am having trouble with opening a specific path in tree presentation (using MorphTreeMorph) when filtering nodes. What I am trying to achieve is that if a node is searched in a tree at level 4, all the parent nodes are opened to show the node searched (hence the user the does not need to open the nodes manually). In Glamour, when combined with filtering, expanding up to the root of the search node works when the parent node is already expanded, otherwise the nodes are not expanded. At the end of the mail, there are two snippets to reproduce the behavior. MorphTreeMorph>>addMorphsTo: from: withExpandedItems: atLevel: is the method responsible for this behavior in Glamour and it seems that nodes are only expanded (to show their children) if they were expanded beforehand. Is there a way to do otherwise in MorphTreeMorph (open paths with non-expanded nodes)? tx. Usman Code snippets in Glamour (Pharo 4.0): | tabulator | tabulator := GLMTabulator new column: [ :c | c row: #one ]; yourself. tabulator transmit to: #one; andShow: [:a | a tree title: 'Show filter paths'; rootsExpanded; children: [:item :x : level | (item < 5 and: [ level < 6 ]) ifTrue: [ {item + 1}] ifFalse:[#() ]]; filterOn: [:text :each | text = each asString]]. tabulator openOn: (1 to: 1) "searching for 3 does not open the path to 3 ?!?!?!" | tabulator | tabulator := GLMTabulator new column: [ :c | c row: #one ]; yourself. tabulator transmit to: #one; andShow: [:a | a tree title: 'Show filter paths'; rootsExpanded; children: [:item :x : level | (item < 3 and: [ level < 5 ]) "to stop adding infinite children" ifTrue: [ level = 4 "plug a node 5 deep down and see if we can find the path" ifTrue: [(1 to: 5)] ifFalse: [ (1 to: item * 2) ] ] ifFalse:[#() ]]; filterOn: [:text :each | text = each asString]]. tabulator openOn: (1 to: 2) "searching for 5 correctly opens the path up to 5"
