Then evaluate the following: TestCase methodDict at: #assert: put: 4. TestCase new assert: 'zaraza'. If works, you should have a debugger in SmallInteger >> #run:with:in: otherwise, a crash. I've tested in mac vms like: Squeak 4.2.5beta1U Squeak 5.8b4 and it crash. In Squeak 64-32 5.7b1 it just hangs forever (I guess at some point it will crash). And in Cog it works perfect! The problem is that I am using my own VM and I cannot use COG. So, if Cog has fixed this, I would like to know the changes so that to apply it to my VM. Maybe it is already fixed in latest VMMaker, but I couldn't compile it....(other story) Thanks for any help.

[Pharo-project] Pharo beginner bugs ....
by Guido Stepken Nov. 20, 2010

Nov. 20, 2010

Beginners Bugs in Pharo 1.1 on Linux: In System Browser i choose Tools-Base->Workspace->initization->initialize and see code os := (Smalltalk platformName) hmmm. I open Shout Workspace, type Smalltalk pl ... and i get 'platformFamily' suggested. No 'platformName' offered by Shout completion mode. And: I cannot choose from other offers in suggestion list by clicking with mouse. Why? Linux Problem? Next example: In Shout Workspace i enter: TTSampleFontMorph new openInWorld. <ALT-P> I get an error and a ghostframe, that i cannot delete. And: Completion mode when i enter TTSample ... does not work. Fuck! What are you guys thinking of your work on Pharo, e.g. quality testing? Did you never notice, that even the basics of completion mode in Shout Browser are buggy? Then i open in World Menu: Tools->Filebrowser i get Error:Invalid utf8 input detected We need a perfectly running Pharo on Linux/Wine (Ubuntu 9.10). And no, no MAC here anywhere in schools in germany. Can you imagine, that a teacher and his pupils drive mad on such simple bugs? So i have to teach with SCRATCH or BYOB in class. No serious bugs, no problems. regards, Guido Stepken
