Soon the LaserGame book for Pharo

by stepharo

Hi guys Steve just told me that he is ok that we port his book to Pharo :) This is a great news. So I will start during my spare time.

I would like to know if we can port the tutorial to Pharo and if we can turn it into a book to fit in the open-source book collection we are slowly building (SqueakbyExample, PharoByExample, Seaside, DeepintoPharo). Now since there is no license it is not clear that it is worth the effort.

The tutorial is remarkably still in use to this day. I still get emails from folks thanking me for it or reporting bugs. When the tutorial was written my intended audience was Smalltalk developers wanting to build Test Driven Development (TDD) skills. It was not intended for beginners. But as it turns out lots of beginners have slogged through it. The key concepts I tried to demonstrate were how to do TDD and building good models that were testable. I also wanted to show you could make stand-alone apps using Smalltalk/Squeak for the Mac. To convert the tutorial to VisualWorks might end up being a challenge, but alas, I haven't used VW since the late 90's and I know it's grown a whole lot since those days. So I cannot recommend how you go about doing it. You're welcome to send me questions about it and any design decisions that were made. I don't claim that it is a "proper OO design" or anything like that. Interestingly, I did port the design to Objective-C for the iPhone years ago and the basic design held up fine. The GUI was obviously done differently -- I ended up adopting OpenGL for the GUI. That was work. But it turned out well and has been in the App Store ever since. So if I can help you, drop me a note. -- View this message in context: http://forum.world.st/Can-this-idea-work-tp4753741p4755668.html Sent from the VisualWorks mailing list archive at Nabble.com. _______________________________________________ vwnc mailing list vwnc(a)cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/vwnc

Re: [Pharo-dev] What is forum (was Re: Pharo Crashes)

by Torsten Bergmann

FYI: Forum is available in the config browser. Interesting enough in a recent image Pharo3.0 Latest update: #30829 the ConfigurationOfForum is not visible in Versionner after loading the config into the image (although the class ConfigurationOfForum is there). May be related to the slot class builder issue that is currently discussed. It works and shows up in Versionner when I use an older one (Pharo3.0 Latest update: #30814 for instance) Bye T.

Is there any case it might be needed except when format changes, and old subclasses are invalid? (and will it ever crash even then until change is propagated and the old instances becomeâd into subclasses of proper format?) If not, it might be a decent change to simply change that method to: Class >> superclass: aClass methodDictionary: mDict format: fmt "Basic initialization of the receiver" self format = fmt ifFalse:[self subclasses: nil. ]. super superclass: aClass methodDictionary: mDict format: fmt. so only cases where format changes are actually responsible for re-registering properly updated subclasses. (which excludes addition of shared vars/pool variables) Cheers, Henry

Try the RB Rename for class names in a workspace and then, it will be less cool.
