[Pharo-project] fixing underscores in a trivial manner thanks to SmalllintChecker and Lukas!
by Fernando olivero April 14, 2010

April 14, 2010

Hi all, i just wanted to re post the fix underscore code Lukas posted a while ago. I've just imported Connectors package into pharo, (i'm trying to get a minimal version working ), and stumbled upon the problem of the underscores.. but now thanks to SmallInt rules it was easy and fast to overcome this problem! Thanks!!!! Fernando pd: From previous mail from lukas. 1. Load the code: Gofer new squeaksource: 'rb'; package: 'AST-Core'; package: 'Refactoring-Core'; load. 2. Select the code (packages) you want to fix: environment := BrowserEnvironment new forPackageNames: #('Connectors-Base' 'Connectors-Lines and Curves'). 3. Create the transformation rule: rule := RBUnderscoreAssignmentRule new. 4. Perform the search: SmalllintChecker runRule: rule onEnvironment: environment. 5. Perform the transformation: change := CompositeRefactoryChange new. change changes: rule changes. change execute

[Pharo-project] news about 1.0
by StÃ©phane Ducasse April 13, 2010

April 13, 2010

Hi guys mariano, marcus and adrian got some push to get 1.0 out. I was just on cc: I think that we made a mistake not to roll that publicly via the mailing-list (we will do that for 1.1). Now this is holidays time here, mariano is going to get married and adrian just moved so no internet connection. Tomorrow I will sync with marcus to know if I can help to get this 1.0 version out. If I remember the mails I saw, marcus was looking for the BitBltPluging binaries for the one click image on other platforms than mac os. Stef

Re: [Pharo-project] About getting HashedCollection (another dream happening)
by Ralph Boland April 13, 2010

> Hi levente/igor > this hashedCollection is still on my radar. Now I was wondering if I should > work first on Set with nil or HashedCollection. > Any idea/suggestion? > Stef I think moving Dictionary out from under Set is a great idea. However I am not convinced having a class HashedCollection to share common code between Set and Dictionary is worth it. I would just tolerate the code duplication because these classes are so important. Given that Squeak is going to support HashedCollection though, I would hate to see yet another difference between Pharo and Squeak. I expect that the difference is unlikely to break code shared between Pharo and Squeak though. I was always against allowing the addition of nil to sets. This change means that every time I accidentally add nil to a set the error will go undetected and will be difficult to track down once the problem is discovered. My solution to escape this change in my code will be to subclass Set and any of its subclasses that I use and add code in the subclasses to test for addition of nil and report an error when it happens. This will allow bugs to show up sooner. An alternative is just to modify Set itself by adding a test for adding nil to a set and then reporting an error. This change will break down of course once there are instances of actually adding nil to a set in Squeak/Pharo. Are there any such occurrences is Squeak 4.1? Now that this feature will be in Squeak 4.1, however, we again have the problem of divergence of code between Pharo and Squeak. The problem won't be there immediately but eventually this feature will actually be used in Squeak. Of course the issue here is how often it is useful to allow addition of nil to a Set. For the approximately 100,000 lines of code I have written in Smalltalk the answer is 0 explaining my opposition to this change. For some others though the answer must be different. For me this change will delay my moving my code from Squeak 3.10 to 4.1+ (and might even tempt me to move to Pharo :-)). Note that I use Sets and Dictionaries a lot. When my Squeak project runs 80% of the time is spent on Set/Dictionary operations. Regards, Ralph Boland

[Pharo-project] about sorted
by StÃ©phane Ducasse April 13, 2010

April 13, 2010

Hi levente may be I did a mistake when I integrated some of your changes. I did not look at Squeak before posting (because I'm dead). Now in latest 1.1 several tests for sorted failed because nil is valued while it should not. I read the code and I do not really like the aBlockOrNil. I would prefer to have block all the time. I was wondering if your original idea was to use nil and if this is the case why you thought it was better than just passing a block. sorted "Return a new sequenceable collection which contains the same elements as self but its elements are sorted in ascending order using the #'<=' operator." ^self sorted: [:a :b| a <= b ] Stef

[Pharo-project] Polymorph, font behavior
by nullPointer April 13, 2010

April 13, 2010

Regards. 1- I create a widget ( a button, for example ) 2- I change the font of that widget 3- I change the caption of widget ( #contents: asString ), then the font returns to original font widget ( the font for buttons of current UITheme instance) Is normal that behavior or is a bug? if not bug, exists some way for avoid that? Thanks for the answer :) -- View this message in context: http://n4.nabble.com/Polymorph-font-behavior-tp1838643p1838643.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Thank you John ! Commit what you want :) I forward to pharo mailing list, people may be interested. http://www.squeaksource.com/LaurentLSandbox.html Cheers, Laurent Laffont ---------- Forwarded message ---------- From: John McKeon <p3anoman(a)gmail.com> Date: Tue, Apr 13, 2010 at 4:45 AM Subject: Scamper To: laurent.laffont(a)gmail.com Hello Laurent I hope you won't mind, I made a change to Scamper and posted it to your repository. I set the testWrap: method to return true. Its seems to give a big improvement to the readability of most pages that I have visited with it. Thanks for your work on it, it is working quite well Warm regards John McKeon -- http://jmck.seasidehosting.st
