[Pharo-project] Should I be able to hang my pharo 1.1 image so easily?
by TimM Aug. 18, 2010

Aug. 18, 2010

Hi guys - it seems really easy to hang my seaside image and then have to force quit and restart. I thought that cmd-. was supposed to recover, but it never seems to work for me. Am I doing something wrong? (I am using a pharo 1.1 seaside3.0rc3 image with the mac 4.2.5 vm). I had the following code: modelUpdate self pusher javascript: [ :jsScript | jsScript << (self generateUpdateScriptWith: jsScript) ] generateUpdateScriptWith: jsScript ^aJScript goto: anActionUrl withoutQuery I think that the << operator is adding something that has already been added via aJScript goto: - and so its recursive. Anyway - when I hit this with my browser - the cpu of my Pharo image goes to 99% and I can hit Cmd-. all I want, but eventually it just dies - or I have to do a force quit. Should it be so easy to kill an image like this? Tim

[Pharo-project] Syntax errors while loading a package
by Sean P. DeNigris Aug. 18, 2010

Aug. 18, 2010

After fixing a syntax error while loading a package, how do you resume loading successfully? Motivation: I was loading the HTML package from http://www.squeaksource.com/htmlcssparser. I got a syntax error because "-1" was typed "- 1". I fixed and accepted it in the window that came up, but the load got messed up - specifically many classes had methods that showed in the browser, but the category pane showed no methods. At this point, I couldn't save the package, or even merge, because MC was reporting errors. I removed all the offending classes, and then merged, using everything from the original package except the method I had fixed. It seemed too complicated. What is the best way to handle the above situation?

[Pharo-project] Question about about LintRule
by Cyrille Delaunay Aug. 18, 2010

Aug. 18, 2010

Hello, I'm currently looking a bit at how lint rules work. The current example I'm looking at is: RBTempVarOverridesInstVarRule => this rule check for tmp variables that override an existing instance variable in the class => when such a case is detected, the result is stored like that: result addClass: aContext selectedClass selector: aContext selector. result addSearchString: varName. => so, all variables are just stored one by one in a collection ('searchString') and never linked to the method in which the problem happened. What I wonder is: How are you able then to display, as result, a list of method, and for each of them to highligth the 'problematic' tmp variable? How do you make the the link between a class-selector from the result, and, the variable name causing the problem for this selector?

[Pharo-project] whileTrue: implementation
by Hernan Wilkinson Aug. 18, 2010

Aug. 18, 2010

Hi, when I'm teaching OO one of the most interesting subjects is the implementation of control flow structures with closures. Having to implement #ifTrue: only with objects and messages produces in some students the "click" we are looking for, the "ah!" that makes them see the real difference with procedural languages and most no pure object languages (java, c#, etc). When teaching the execution model, I use the #whileTrue: implementation to show them that it is also possible to implement such a thing with just objects and messages. The last semester to my surprise I saw that the #whileTrue: implementation in Pharo is cumbersome, at least for teaching porpoises, because it is based on the "hidden" detail that #whileTrue: is inlined, therefore never sent and its method never executed. The VisualWorks implementation is clearer because it is a recursive implementation that seems to work without knowing that #whileTrue: is inlined (and has a nice comment that explains that implementation detail). Anyway, just for teaching porpoises I thought that providing another implementation would be nice, an implementation based on the execution context, an implementation completely based on objects and messages. For example: whileTrue: aBlock self value ifTrue: [ aBlock value. thisContext restart ] I think it is an interesting example that allows the students to see how we can manipulate the execution environment from inside Smalltalk itself... Anyway, just a comment... not sure if it makes sense to change the implementation just because of this, but maybe putting a comment explaining this option would be nice. Bye, Hernan.
