[Pharo-project] Pharo problem with Windows 7

by Torsten Bergmann

What is the value of "f" (the filename) when you hit Alt+. ? Where did you install? Maybe it is a problem with the security to not being able to write under c:\Program Files\...? Not able to test it here this week but did you try to install Pharo under for instance c:\foo\ as an alternative and try to run it from there? If that doesnt help did you try to run Pharo as Administrator (right click on exe should allow you to do that), maybe you can also try to set the compatibility mode (right click on exe, select "Properties", then select compatibility to WinXP for instance). Try that and report if any of this helps. Bye T. -- GMX DSL Doppel-Flat ab 19,99 €/mtl.! Jetzt auch mit gratis Notebook-Flat! http://portal.gmx.net/de/go/dsl

Re: [Pharo-project] What is a primitive method?

by Eliot Miranda

Hi Oscar, see Object class>>whatIsAPrimitive. Further, most of the primitive methods you're seeing are methods that answer self, nil, true false or an inst var. See the difference between these: SystemNavigation new browseAllSelect: [:m| m isQuick] SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick not]] SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick not and: [(#(117 120) includes: m primitive) not]]] HTH Eliot On Thu, Oct 21, 2010 at 9:18 AM, Oscar E A Callau <oalvarez(a)dcc.uchile.cl>wrote: > > Hi all, > > I have a (basic) question: > > What is a primitive method? > > In pharo 1.1.1, we have CompiledMethod>>primitive that basically return: > > 0 if the method is not a primitive method > >0 otherwise > > But if you execute this on i.e. Number>>isNumber or Morph>>#model compiled > methods you get that these two are primitive methods.

[Pharo-project] Morphic application to production questions

by Esteban Lorenzano

Hi, Finally I managed to get one application made with morphic. I developed the app inside a StandardWindow, and that's ok, but now I want to move it to production, so I need to do some tasks, some of them easy to solve, and some of them not (at least for me). This is what I think is needed: 1) remove all morphs (this is easy, already done) 2) add morphs in world instead StandardWindow (easy too, and already done). 3) disable control+click, cmd+., etc. (I don't know how to do this) 4) disable morph drags (my morphs, placed inside the world, can be moved, I don't want that) 5) change the behavior of "quit" when pressing close window (red button) 6) disable debugger on errors ...and I don't know if there are other things. Can you help me with points 3-6? Do you know other tasks needed? Thanks, Esteban

[Pharo-project] some patterns I would like to **kill**

by stephane ducasse

Hi I was reading Pluggable and friends I identified some patterns. The respondsTo plague Examples: color := self fillStyle asColor. (self labelMorph respondsTo: #enabled:) ifTrue: [self labelMorph enabled: self enabled]. (self labelMorph respondsTo: #interactionState:) ifTrue: [self labelMorph interactionState: self interactionState] (self labelMorph respondsTo: #enabled:) ifTrue: [ self labelMorph enabled: aBoolean]. (self enabled not and: [self label isMorph and: [(self label respondsTo: #enabled:) not]]) by construction a labelObject should be a morph and it should answer enabled: and the case where this is not the case should be fixed. Using submorphs to avoid one single inst var makes code quite ugly to read: labelMorph "Answer the actual label morph." self hasSubmorphs ifFalse: [^nil]. self firstSubmorph hasSubmorphs ifFalse: [^nil]. ^self firstSubmorph firstSubmorph

This is really strange. We've tried for a while to save a rep on a local repository, on squeaksource, no success... Anyone experienced this already?

[Pharo-project] Pharo problem with Windows 7

by Christian Eduardo Palomares Peralta

Hi everyone I'm new on Pharo, i downloaded pharo for Windows ( http://pharo-project.org/pharo-download) everything works fine until i try to save a package in the Monticello Browser, the "Snapshotting Methods" takes age. Several minutes pass and nothing is saved. Selecting a local repository does not help neither in case squeaksource would be down. I use the VM 4.0.2. I tried the Pharo1.1 one click image, the Windows Installer, and the Seaside One click image. Same result. When I press Alt-. the debugger always open on the retryWithGC: in the method: MultiByteFileStream>>open: fileName forWrite: writeMode "Open the file with the given name. If writeMode is true, allow writing, otherwise open the file in read-only mode." "Changed to do a GC and retry before failing ar 3/21/98 17:25" | f | f := fileName asVmPathName. fileID := StandardFileStream retryWithGC:[self primOpen: f writable: writeMode] until:[:id| id notNil] forFileNamed: fileName. I disabled my antivirus, but the problem persist Does anyone can help me with this problem?

[Pharo-project] About Object and Model

by stephane ducasse

Hi guys I'm reading Object and I have the impression that some methods are in Object while there should be on Model. when: anEventSelector send: aMessageSelector to: anObject exclusive: aValueHolder okToClose.... taskbarIcon taskbarLabel May be some of these methods should grouped in traits, then applied to Model. Then if the user wants something else than Model to play the game he can simply apply a trait. I think that this hierarchical decomposition is often forcing us to stack methods in the wrong place I think that the composition is way stronger and much more flexible than hierarchical ordering. tell me what you think. I would like to have a nice Object class. Stef
