Relative position of submorph
by Ulrich Vollert May 10, 2011

May 10, 2011

Hi, I am doing my first steps with Pharo, and I am deeply impressed and amazed about this wonderful development world of Smalltalk. Thanks to all developers who made Pharo available! As my first project, I am trying to develop an animation and want to animate a subclass of ImageMorph named PlaneMorph in a StandardWindow. I defined a method PlaneMorph>>step which calculates new positions like: step .... self position: newPosition When adding my PlaneMorph to a StandardWindow like window addMorph: PlaneMorph new the coordinates are not relative (inside) of the window but relative to the main window of Pharo. My solution to position PlaneMorph relative to the position of the StandardWindow: I tell the PlaneMorph to which surrounding window it belongs (PlaneMorph new window: window), store the window in an instance variable of PlaneMorph and positon it in PlaneMorph>>step relative to the window as self position: newPosition + window position Is this solution good design? I wonder whether it is a good idea that the PlaneMorph knows about the window. Regards, Ulrich

moose = smalltalk ambassador
by Tudor Girba May 10, 2011

May 10, 2011

Hi, Moose (http://moosetechnology.org) is a Smalltalk ambassador. Actually, I think it's the best ambassador we have right now to persuade professional developers to look into Smalltalk. Let me tell you why. Moose is a platform for software and data analysis and includes components like: Glamour, Mondrian or PetitParser. Moose solves a real and important problem that developers (both Smalltalkers and non-Smalltalkers) have: how to improve the productivity of the effort spent on assessment. Moose is an innovation in this domain because it enables a completely different approach through which developers craft their own tools fast (http://humane-assessment.com) The cool thing is that they build these tools by programming Smalltalk in Pharo, and thus they get to learn the language and the platform first. Moose also comes with exposure. For example, this year I will be presenting Moose and humane assessment at some large industry oriented conferences: - Jazoon (http://jazoon.com) - GotoCon Aarhus (http://gotocon.com/aarhus-2011/) - GotoCon Amsterdam (http://gotocon.com/amsterdam-2011/) All in all, if you want to promote Smalltalk, and Pharo in particular, you might want to look into it. And you are always welcome to contribute, follow us and make noise: - http://www.moosetechnology.org - http://twitter.com/#!/moosetechnology - http://www.facebook.com/pages/moosetechnologyorg/152851281427491 Cheers, Doru -- www.tudorgirba.com "No matter how many recipes we know, we still value a chef."

Monticello: How to visualize history?
by Nick Chen May 10, 2011

May 10, 2011

Hi Is there a nice way to visualize the history of Monticello repository? In particular, I would like to be able to quickly identify the presence of branching/merging. http://forum.world.st/file/n3508002/MonticelloBrowseHistory.png Consider the screenshot above. Without a graphical visualizer, it is hard to tell that LanguageOfLanguages-NC.42.mcz and LanguageOfLanguages-jamie.42.mcz branched out from LanguageOfLanguages-jamie.41.mcz. Their names might hint that they do (because of the "42") but that isn't always reliable. Additionally, without a graphical visualizer, it is also impossible to tell that I did a merge in LanguageOfLanguages-NC.50.mcz unless I look at the commit message and check the ancestors. If no graphical visualizer exists, how do Smalltalkers normally check for branching/merging?

Inheriting traits
by DougEdmunds May 9, 2011

May 9, 2011

The definition of ClassA uses a trait, such as "uses: TEasilyThemed" ClassB is a subclass of ClassA. Does ClassB inherit the trait from ClassA, or does ClassB have to separately state its own "uses:TEasilyThemed" clause? -- View this message in context: http://forum.world.st/Inheriting-traits-tp3510198p3510198.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [Pharo-project] compiled VM with Alien for JNIPort
by laurent laffont May 9, 2011

May 9, 2011

OK I will try. For info I want to use JNIPort just to write some small Java script to learn and prototype on several Java frameworks. Prototyping with Java is tedious. I've tried Groovy, it's better but lacks all goodies of Pharo IDE. So I thought JNIPort would be a good candidate to play with. Laurent.
