Global package cache
by Francois Stephany May 18, 2012

May 18, 2012

Hi there, I've seen some people using a shared package cache to avoid downloading package that were already used. Is this a preference somewhere or do you set manually: MCCacheRepository default: (aFileDirectory somewhere) ? Cheers, Francois

SystemWindow initial labelling from model
by Daniel Lyons May 18, 2012

May 18, 2012

A bit confused on this. You can define labelString on your model, pass an instance to SystemWindow, and it doesn't get the label. Seems you either have to send #label: to the SystemWindow instance or send #update:#relabel to pick it up. Is this by design? Am I missing something? Thanks, -- Daniel Lyons

is Trait a behavior?
by Martin Dias May 18, 2012

May 18, 2012

Hi all I have some methods receiving either a Class or a Trait instance as parameter, so I usually call variables with names like 'aClassOrTrait'. Searching for a more synthetic name, I wonder if 'aBehavior' would be fine. But IMO these examples show contradictions: - Trait *is* a behavior: TBehaviorCategorization users ---> an IdentitySet(Class Trait) TPureBehavior users ---> an IdentitySet(TraitBehavior Behavior) (actually this makes me think 'aPureBehavior' is another alternative for my variables) - Trait is *not* a behavior: TBehaviorCategorization isBehavior ---> false TClassAndTraitDescription users ---> an IdentitySet(ClassDescription TraitDescription) (I both are behaviors, why not call it TBehaviorDescription?) Thanks in advance for your help. MartÃn

ANN: Moose apprentice course - June 2-3
by Tudor Girba May 16, 2012

May 16, 2012

Hi, I am happy to announce that I will organize the first Moose apprentice public course. This is an introductory course on how to use the Moose analysis platform for putting humane assessment into practice. It is dedicated to software engineers, and the concepts covered include model navigation, querying techniques, code metrics, and visualizations. The course sessions are accompanied by hands-on exercises. Here is the official announcement: http://www.humane-assessment.com/blog/free-moose-apprentice-course-june-2-3… Cheers, Doru p.s. I am announcing this course here, because it can be interesting for the Smalltalk community (and Pharo in particular) in two ways: - learn how to use Moose in assessment scenarios, and - given that the course typically reaches non-Smalltalk programmers, it can be a good advertisement for Smalltalk (they actually get to program Smalltalk) -- www.tudorgirba.com "If you interrupt the barber while he is cutting your hair, you will end up with a messy haircut."

Monticello browser question
by Werner Kassens May 16, 2012

May 16, 2012

Hi, after having loaded some packages (dont remember which one was responsible), i noticed the package-type git could be added as repository in the monticello-browser. this leads me to the question whether i could add a repository on a github site directly, so that i dont have to clone that site first to my disk, before i can load a package? werner

#allSendersOf:inPackageNamed: vs. #allCallsOn:localToPackage:
by Helene Bilbo May 16, 2012

May 16, 2012

In SystemNavigation, what is the difference between #allSendersOf:inPackageNamed: and #allCallsOn:localToPackage: ? Is there a reason to prefer one over the other, when looking for senders of a specific message in a specific package? And why is the word âcalls" used? I was proud to have learned from the Pharo book that there are no calls, but only message sends? -- View this message in context: http://forum.world.st/allSendersOf-inPackageNamed-vs-allCallsOn-localToPack… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Monticello question (package renaming)
by Juan Ignacio Vaccarezza May 15, 2012

May 15, 2012

Hi all, Question: Â¿ Is it posible to rename packages in monticello? Meaning by renaming not create a whole new history, but the history contemplates the renaming. Context: I started a project, with a category layout. Then I saved and track the project history using monticello. Then I realized that my package division was wrong (infered from the categories). So I decided to re-think my projects category layout and consecuently renamed the categories. Then new packages shall be created, and my project's history will be gone. Thanks for the help. Regards, Juan

Beginner's questions
by Edouard Klein May 14, 2012

May 14, 2012

Hi all, I tried to build my first user interface with Pharo. I ran into some problems, I have a bunch of questions. These are certainly quite simple to answer for any veteran... If any of you could so kind as to not only answer them but also to tell me where I sould have looked for the answer, this would be awesome. I used Pharo By Example as well as the pharocasts and the occasional google search to find info. My code can be found at : http://ss3.gemstone.com/ss/MakeMeASandwich.html - I build the UI by hand, this is tiresome. Is there a GUI UI builder ? I found Morphic designer (https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki…) and UIBuilder (http://forum.world.st/CLFramework-UIBuilder-td1302485.html) but it is unclear if any or both are the Right Way (tm) of doing things with Pharo. - As you can see if you do RecipeEditor new open, there is a lot of wasted space. Lists do not expand to take all the vertical space they could. What is the workaround for that ? - I have a list created by : nodeList := ListModel new list: SortedCollection new. put on screen by : builder newListFor: self list: #nodeList selected: #selectedNodeIndex changeSelected: #selectNodeAtIndex: help: 'Liste des Ã©tapes'. and I use : nodeList list at: (nodeList selectionIndex) on the press of a button to get the selected element of a list. I would like this list to allow for multiple selection, and I would like to get the list of selected elements. I tried to fool around with some methods having "multiple" in their name, but to no avail. - The text fields require the user to accept (command-S) the modification before I can get the content with getText. Is there a good way to get the non accepted text ? I tried to to an UI with tk before, and compared to that it has been a breeze with Smalltalk, the way one can write the highest level call and then use the debugger to create methods and variables on the fly is very enjoyable. Thank you in advance, Cheers, Edouard.
