[Pharo-project] String widgets for GUIs built using ToolBuilder
by Ralph Boland March 19, 2010

March 19, 2010

I originally posted this on Squeak-Dev but I didn't get a response so I am hoping someone on this list can help. I will release the code I am working on to SqueakSource. I assume it will work in Pharo as well. If it doesn't let me know and I will clean up the problems. ================================= I am trying to subclass TestBuilder (SUnitGUI) for my own testing facility. TestBuilder builds a GUI using ToolBuilder and I am trying to build my GUI using ToolBuilder as well. I need to use an input field and want to add a StringMorph like widget to label the input field. The only way I can see to do this using ToolBuilder is to use another input field for my input field label string. There has to be a better, standard, way of doing this. Can someone tell me what the standard way, or some reasonable way, of labeling my input field is when using ToolBuilder? Regards, Ralph Boland -- Had a wife and kids in Florida, Jack (Nicklaus) Went out for a "ride" but I couldn't get back As a ten timer being hunted down OR When the wife found out who I was knowing (biblically speaking) I hit a hydrant and I just kept going (till I hit a tree). ...

[Pharo-project] Sets with nils using SetElement(s)
by Igor Stasenko March 19, 2010

March 19, 2010

i added a changesets into a corresponding tracker issue (#1907) please, be advised, that in Squeak it was adopted after HashedCollection refactoring. And a scope of changes is wider than my own (it includes KeyedSet and KeyedIdentitySet, which i haven't touched before). Still, all tests are green, except there is unimplemented #errorNoFreeSpace , which can be found in trunk's HashedCollection ). -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] RefactoringManager and RBNamepsace error?
by Fernando olivero March 19, 2010

March 19, 2010

Lukas, i have the following problem: model := RBNamespace new. Then executing successive RenameRefactoring's using the same model yields an Error. 1. ClassA -> ClassA2 OK 2. ClassA2 -> ClassA3 OK 3. ClassA3 -> ClassA4 ERROR! I've tracked it down to this: 1. RenameRefactoring>>execute self primitiveExecute. RefactoringManager instance addRefactoring: self 2. RefactoringManager>>addRefactoring: aRefactoring RefactoryChangeManager instance performChange: aRefactoring changes. refactorings add: aRefactoring class name 3. Refactoring>>changes ^self model changes which answers all the changes! { ClassA rename: #ClassA2! ClassA2 rename: #ClassA3! ClassA3 rename: #ClassA4! } Why does a particular refactoring answers all the models changes? And not just the ones it introduced? The problem is in #performChange: will apply over and over all the changes, and not just the last one. Lukas, do you think i'm incorrectly using the namespace and refactoring's? Are namespace supposed to be used once and later ditched? My goal is to have a GauchoSystem which nows all the changes (with undos!) that have happened, that's why i'm using always the same namespace. Thanks, Fernando pd: a test that reproduces the problem. >>testSucessiveRefactoringsError | namespace | namespace := RBNamespace new.

[Pharo-project] unused temporal variables
by Mariano Martinez Peck March 19, 2010

March 19, 2010

Hi. I remember in previous Pharo images when you save a method that has unused temporal variables you have a popup that said "XXX is unused, don't you want to remove it ?" or something similar.... We then removed that. Ok, cool. Now...suppose I want to examine all the system to detect all those unused temporal variables and remove them (yes, recompiling), does someone have an idea how to do that ? Thanks! Mariano

[Pharo-project] CleanUp unused packages
by Mariano Martinez Peck March 19, 2010

March 19, 2010

http://code.google.com/p/pharo/issues/detail?id=2165 There are some packages that has to be removed. For example: - PinesoftEnhancementsForFreeType: This package is empty - FixUnderscores: This package is old, is not needed any more and has no references The fix is to evaluate: (MCPackage named: 'PinesoftEnhancementsForFreeType') unload. (MCPackage named: 'FixUnderscores') unload. Cheers Mariano

[Pharo-project] (aDateAndTime offset: '0:12:00:00') = '1901-01-01T00:00:00+12:00'
by stephane ducasse March 19, 2010

March 19, 2010

in Squeak (aDateAndTime offset: '0:12:00:00') = '1901-01-01T00:00:00+12:00' true in pharo (aDateAndTime offset: '0:12:00:00') = '1901-01-01T00:00:00+12:00'. false. Apparently the false in pharo comes from a bug in readFrom: in DateAndTime Now the question is does it make sense to have a DateAndTime = to its string representation. For me I would prefer not (aDateAndTime offset: '0:12:00:00') = '1901-01-01T00:00:00+12:00' -> false (aDateAndTime offset: '0:12:00:00') printString = '1901-01-01T00:00:00+12:00' -> true DateAndTime>>= comparand "comparand conforms to protocol DateAndTime, or can be converted into something that conforms." | comparandAsDateAndTime | self == comparand ifTrue: [^ true]. comparandAsDateAndTime := [comparand asDateAndTime] on: MessageNotUnderstood do: [^ false]. ^ self offset = comparandAsDateAndTime offset ifTrue: [self hasEqualTicks: comparandAsDateAndTime ] ifFalse: [self asUTC ticks = comparandAsDateAndTime asUTC ticks] What do you think Stef

Hi I would like to initiative a task (monthly) for us. I would like to get really good tests coverage for some of the core classes. For example Date, Time, Duration, DateAndTime. This is really important in the long term to get sure that we identify bugs as soon as they appear. It would be really good if we could get team up and fix that together. Does anybody want to help? I started to fix some bugs there and write more tests in the process of fixing tests. Stef

[Pharo-project] MethodProperties question
by Mariano Martinez Peck March 19, 2010

March 19, 2010

Hi folks (Marcus ?). I saw this class was removed, however: 1) The class MethodPropertiesTest is still alive. Shouldn't we remove it ? 2) After evaluating "ScriptLoader new cleanUpForRelease" if I inspect SystemNavigation default obsoleteClasses I have a "AnObsoleteMethodProperties" Cheers Mariano
