AFAIK the idea was to integrate NB into Pharo 2.0. So shouldnt this be done first ...

[Pharo-project] I don't agree with DummyXXX

Nov. 21, 2012

>From what I understand, Dummy means something different. I have using that for class names. More accurate names can be found. I would rename: DummyUIManager -> HeadlessUIManager DummySystemProgressItem -> NullSystemProgressItem DummySoundSystem -> NullSoundSystem what do you think? do you have better names? -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Package-pane (or 6-paned) browser for Pharo?
by Stephen Travis Pope Nov. 21, 2012

Nov. 21, 2012

Hello all, I'm just moving to pharo, and wanted to port the "package-pane browser" that I originally wrote for Smalltalk-80 and then ported to Squeak. The squeak code obviously doesn't run in pharo, and I wanted to ask whether anyone had already ported it (or something like it). Basically, the tool is just like the standard system browser, except that it parses the class category names into a 2-level hierarchy, making the top-level list much smaller and more manageable (see the screen shot below). Does this already exist? ...any reply appreciated... stp -- Stephen Travis Pope Santa Barbara, California, USA http://HeavenEverywhere.com

[Pharo-project] Loading dependencies
by roberto.minelli＠usi.ch Nov. 21, 2012

Nov. 21, 2012

Hi, At the moment I'm creating an analysis tool for Git repositories. I'm versioning my source code on Smalltalkhub, so that I can easily load my code in a fresh image, when needed. My project depends on several external packages such as the Filesystem-Git, Fuel, and the last version of Filesystem. I was wondering if it's possible to add such dependencies programmatically so that once I load my project from Monticello dependencies are added as well. I heard that Metacello is probably suitable to handle dependencies, but it would be glad to hear an opinion from you. Thanks in advance, Roberto

[Pharo-project] Fwd: [ANN] Limbo: a simple shell wrapper for NativeBoost
by Igor Stasenko Nov. 21, 2012

Nov. 21, 2012

Ah, ok , so its even better than i thought. Indeed , if purpose of Limbo is to provide an interface to exec(ve) system functions, then there's no need to care a lot about VM state after fork() call.. Also, Max, did you considered of using system() call? It is much easier.. The downside that it doesn't allows you to control input/output channels of running child process, of course. Anyways, your project can give a definitive answer to a question, which i asked some time ago: - can OSProcess functionality be implemented via FFI or not.. On 20 November 2012 17:56, David T.

Re: [Pharo-project] About new TxText text model
by Stephan Eggermont Nov. 20, 2012

Nov. 20, 2012

Hi, I've taken a look at the TxText text model, and it seems rather limited. I'm a bit confused about the expectations for this code: is this supposed to be just for editing smalltalk methods? The current Text system looks to me more like a limited implementation of the OpenStep/GNUStep/Cocoa text system. That separates concerns and allows high quality layouts. David Chisnall seems to know something about those systems http://www.informit.com/articles/article.aspx?p=1602820 Cheers, Stephan

[Pharo-project] SortedCollection>>=
by Hernan Wilkinson Nov. 20, 2012

Nov. 20, 2012

Hi, I'm a little surprised with the current SortedCollection #= implementation... it is: = aSortedCollection "Answer true if my and aSortedCollection's species are the same, and if our blocks are the same, and if our elements are the same." self species = aSortedCollection species ifFalse: [^ false]. sortBlock = aSortedCollection sortBlock ifTrue: [^ super = aSortedCollection] ifFalse: [^ false] and my surprise is because it compares the sortBlocks that makes the simplest case to fail like this one: (SortedCollection sortBlock: [ :a :b | a < b ]) = (SortedCollection sortBlock: [ :a :b | a < b ]) One could argue that if we remove the sortBlock comparison then : (SortedCollection sortBlock: [ :a :b | a < b ]) = (SortedCollection sortBlock: [ :a :b | a > b ]) would return true... but is that wrong? ... or is the philosophy to use the message #hasEqualElements: on this cases? BTW, VisualWorks implementation is the same as pharo, but the BlockClosure>>= is different and that's why it works as at least I expected :-) Bye, Hernan -- *HernÃ¡n Wilkinson Agile Software Development, Teaching & Coaching* *Phone: +54 - 011 - *6091 - 3125* Mobile: +54 - 911 - 4470 - 7207 email: hernan.wilkinson(a)10Pines.com site: http://www.10Pines.com <http://www.10pines.com/>* Address: Alem 693, Floor 5 B, Buenos Aires, Argentina

[Pharo-project] Pharo Images before 1.0
by Oscar E A CallaÃº Nov. 20, 2012

Nov. 20, 2012

Hi guys, I was wondering where I can find/download versions of pharo images below 1.0 ? Why I need this? Because I have a compilation of Smalltalk projects that are from Dic-2009, and I need to load/run them. Cheers.
