[Pharo-project] SmallDictionary ?? vs RB SmallDictionary
by StÃ©phane Ducasse Jan. 13, 2009

Jan. 13, 2009

Hi all We have no idea where SmallDictionary come from? It was not in 3.9 Especially since Set |array tally| Dictionary SmallDictionary |keys values size| and it does not seems defined as needed. RBSmallDictionary seems much better. We are currently applying traits tests to these classes and this is really interesting to see the bugs popping out. Nicolas sent a fix for capacity that I'm planning to integrate but I was wondering. Stef

[Pharo-project] Help clarify
by Hilaire Fernandes Jan. 13, 2009

Jan. 13, 2009

I need to write a DoubleLinkedList, checking for LinkedList I saw add: link after: otherLink "Add otherLink after link in the list. Answer aLink." | savedLink | lastLink == otherLink ifTrue: [^ self addLast: link]. savedLink := otherLink nextLink. otherLink nextLink: link. link nextLink: savedLink. ^link. Why is savedLink needed ? Why not: lastLink == otherLink ifTrue: [^ self addLast: link]. link nextLink: otherLink nextLink. otherLink nextLink: link. ^link. Are there any hidden reason I don't see? -- http://blog.ofset.org/hilaire

[Pharo-project] new look / monticello UI
by Michael Roberts Jan. 13, 2009

Jan. 13, 2009

guys, I'm liking the new UI in Pharo. I've noticed in the Monticello browser that the buttons now don't have an enabled/disabled state. Is this intentional or noticed? thanks, Mike

[Pharo-project] Very strange behavior with MC
by Alexandre Bergel Jan. 12, 2009

Jan. 12, 2009

Dear all, I just save a new version in PharoInbox, but this version appears to be empty. I checked on squeaksource [*]. In Pharo, it seems that two files are being saved (.143(142).mcd and . 143.mcz) [**]. when I browse .143(142).mcd I see all the content (probably because it is local to my machine). When I browse .143.mcz it is empty. What this .mcd file is about? I am not the only one to experience this. Anyone had an idea what's going on? I haven't closely followed the list of changes that were included in Pharo.

[Pharo-project] [ANN] WatchIt
by HernÃ¡n Morales Durand Jan. 11, 2009

Jan. 11, 2009

Dear all, You can use again the "Watch It" debugging functionality written by Ned Konz back in 2002. This is the description: "This adds a 'watch it' choice to the context menus in text editors. This will take the selection, make a BlockContext out of it, and give you a Morph that will display the value of that block every half second. It can be used, for instance, from the Debugger to display an instance variable as your program runs." Test 1: Paint and select "watch it" from the menu: World currentHand cursorPoint Test 2: "debug it" the following lines, once inside the debugger, paint the "collection", select "watch it" and voilÃ ! | collection | collection := #(1 2 3 4) asOrderedCollection. collection add: 88. collection add: 99. collection Tested under: -Squeak3.9 -Squeak3.10.2 -Pharo0.1Core-10201 Cheers HernÃ¡n

[Pharo-project] Fun with Smalltalk in high school
by Hilaire Fernandes Jan. 11, 2009

Jan. 11, 2009

Yes, I forgot, it is Pharo related! Now, I want in the future to redesign the DrGeo UI to take advantage of Polymorph. Computer are good for dynamic stuff, I love to mix interactive geometry and analytic calculus. With DrGeoII it is becoming so much fun. I would have love to play with that at high school. See this post, in French only, but a comment at the end of the article propose a Google translation http://blog.ofset.org/hilaire/index.php?post/script-drgeo Hilaire
