[Pharo-project] Legacy FileDirectory
by Camillo Bruni Jan. 17, 2013

Jan. 17, 2013

I finally found the motivation to properly package my compatibility package. http://smalltalkhub.com/#!/~dh83/fisleg/packages/FileSystem-Legacy For people who want to migrate to 2.0 but depend on FileDirectory, they can load this compatibility package for 2.0 which will add a mock FileDirectory. It will mostly forward to FileReference. This is legacy software and should only be used for migration ;) best cami

[Pharo-project] UI blocked
by Janko MivÅ¡ek Jan. 8, 2013

Jan. 8, 2013

Hi guys, My 1.3 #13299 image is blocked again, but just UI not responding to any input events, while Aida web app server is running smoothly in backrgound. >From Transcript I can see that last action was a new image backup procedure, which is done simply by : OSProcess waitForCommand: 'cp some.image some-bck.image'. This procedure is called from a background process and report to Transcript its start and end. Is there something wrong with that? Or is some interference with OSProcess semaphores? (I saw such suspicious thing once before). In any case, is there a way to unblock image now? Ctrl or Alt . doesn't help. Best regards Janko -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

Re: [Pharo-project] Is there a simple example of how to create a GUI form in Pharo or Squeak?

Hi, two good sources of information on GUI building are http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html?utm_source=… http://book.pharo-project.org/book/LanguageAndLibraries/GUI/?_s=yllsSvKBo5c… They're not that hard to find (if you are aware of the Collab book and the pharocasts).

[Pharo-project] [ANN] NBOpenGL update
by Igor Stasenko Jan. 6, 2013

Jan. 6, 2013

Hi there, for those, who interested, i updated a NBOpenGL configuration. Changes are: - updated GL API to most recent available (taken directly from opengl specs). Now there is about 300 more methods to explore :) - finally dealt with win32 support code and made it working again - fixed the GLX function prefix , which should be 'glX' not 'glx' To load it in 1.4 use: Gofer new squeaksource: 'NBOpenGL'; package: 'ConfigurationOfNBOpenGL'; load. and then (ConfigurationOfNBOpenGL project version: '1.0.2') load I did not tested the update thoroughly.. so i would appreciate if people will try it out and tell how it goes. -- Best regards, Igor Stasenko.

[Pharo-project] Extracting a ZipArchive in 2.0
by Vanessa PeÃ±a Araya Jan. 3, 2013

Jan. 3, 2013

Hi, I want to extract a ZipArchive in Pharo 2.0, as the title says. I'm trying to do it with this: zipArchive extractAllTo: aDirectory informing: bar overwrite: false I'm trying the new file system but my problem is that ZipArchiveMember calls a method called "assureExistence", which does not exist... anywhere. Has anyone experience something like this? Thanks, Vanessa.

[Pharo-project] [ENH]: MCHttpRepository Authentication (Issue 6449)
by Sean P. DeNigris Jan. 2, 2013

Jan. 2, 2013

http://code.google.com/p/pharo/issues/detail?id=6449 We should be able to say, "MCHttpRepository logInto: serverUrl as: username withPassword: passwordString" Is there any use case for not using the server credentials with a particular repo i.e. myserver/ss has credentials, but myserver/ss/myrepo uses different/no credentials? If we assume that all repos with a given prefix will use the same credentials, the implementation will be much simpler... Conversation-starter in the inbox. Please take a look and comment, but do not integrate. Name: SLICE-Issue-6449-ENH-MCHttpRepository-Authentication-SeanDeNigris.1 Hack together an implementation to start the conversation. ***This should NOT be integrated*** -- View this message in context: http://forum.world.st/ENH-MCHttpRepository-Authentication-Issue-6449-tp4641… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] About morph layout
by Igor Stasenko Jan. 2, 2013

Jan. 2, 2013

Hi, just wanna share some ideas about how we can cleanup morph a bit. Layout.. bizarre. There are so many methods dedicated to laying out morphs that it easy to get lost. For me the main mystery and source of confusion is that there actually two different groups: - methods to control morph's own layout (in respect to its parent) - methods to control morph's children layout (something called layoutPolicy) the problem is that both APIs are found in single class, and most of them contain 'layout' word in it, so it is really hard to determine which one to use and when.. Over a years, i seen that people learned how to use existing functionality, without delving deep into implementation detail. But if you try to extend/change behavior (in your subclass), you will quite soon find out that it is really hard to tell with 100% certainty that the methods you override is the right place for your customization. Also, an important detail is extremely polluted protocol(s), making Morph a GOD class, with so many functions that it is unbearable. So, what i want to propose is same as i proposed to introduce for "SmalltalkImage" is to use "scoping" accessors , or "delegate" accessor to get access to part of functionality with clear context. Remember: Smalltalk vm version Smalltalk tools browser so, lets see how code might look like if we apply same approach to morph protocols: Example. Original: column := AlignmentMorph newColumn vResizing: #shrinkWrap; hResizing: #shrinkWrap; layoutInset: 1; borderColor: Color black; borderWidth: 0; wrapCentering: #center; cellPositioning: #center; color: Color white; yourself. Change: column := AlignmentMorph newColumn. column color: Color white. column layout shrinkWrap. "v and h both" column border width: 0; color: Color black. column childLayout inset: 1; wrapCentering: #center; cellPositioning: #center. Cons: - a code is a bit more elaborate. That because, of course, we cannot merge everything into single cascade. Pros: - from code it is clear, which properties belong to which parts of functionality. You cannot confuse, for instance, whether 'wrapCentering' property controls morph's own layout or a layout of its children - most important, we can considerably shrink Morph's protocol by removing all direct accessors and instead put them into delegated behaviors. More than that, a delegates don't need to be a dummy state holders (like most of properties are now), but actually an object(s) which conform to certain protocol.. For instance, if we have a 'border' as a delegate, and morph wants to draw it, it could just tell: MyMorph>>drawOn: aCanvas self border drawOn: aCanvas btw, then it is actually makes sense having a BorderedMorph subclass, which a) introduces 'border' delegate b) cares to draw its border in contrast to Morph who shouldn't. As well as in case of layouts, you can tell: morph layout changed. or morph childLayout layOutChildren. etc. -- Best regards, Igor Stasenko.

[Pharo-project] A tantalizing path of dealing with multiple concerns...
by Igor Stasenko Jan. 2, 2013

Jan. 2, 2013

areasRemainingToFill: aRectangle "Pushed up from BorderedMorph, all cases tested for there are supported by basic Morph." "Morphs which achieve translucency by other means than fillStyle will have to reimplement this" "Fixed here to test the fillStyle rather than color for translucency. Since can have a translucent fillStyle while the (calculated) color is not." self fillStyle isTranslucent ifTrue: [^ Array with: aRectangle]. self wantsRoundedCorners ifTrue: [(self borderWidth > 0 and: [self borderColor isColor and: [self borderColor isTranslucent]]) ifTrue: [^ aRectangle areasOutside: (self innerBounds intersect: self boundsWithinCorners)] ifFalse: [^ aRectangle areasOutside: self boundsWithinCorners]] ifFalse: [(self borderWidth > 0 and: [self borderColor isColor and: [self borderColor isTranslucent]]) ifTrue: [^ aRectangle areasOutside: self innerBounds] ifFalse: [^ aRectangle areasOutside: self bounds]] ... the whole Morphic code fall victim of rounded corners (and borders , of course). I wonder, is there any way to a) have multiple concerns b) at same time, have a clean code ? But i suspect that smalltalk is not powerful enough for that. :) -- Best regards, Igor Stasenko.
