[Pharo-project] Website
by Alexandre Bergel March 2, 2009

March 2, 2009

Hi All, The download section of the website is rather incomplete. > http://www.pharo-project.org/download I added a while ago a couple of sentences in the download section on the google website. Maybe the pharo-project.org web administrator could cut&paste it. I could accessory do it, however I do not have an access to the cmsbox.

I think that there was a split/join package somewhere. Does anybody know where it is? At one point it was planned to get added to squeak and nothing happened. Stef

[Pharo-project] Dynamic dead code alpha version
by StÃ©phane Ducasse March 2, 2009

March 2, 2009

Hi I continued to code a little tool based on code of Alain to detect deadcode, so far I'm too sick to have clear idea why it freezes on Morph. However it works on ClockMorph and IconicButton. If you want to have fun save your image before MCHttpRepository location: 'http://www.squeaksource.com/MetaF' This package got inspired heavily by code given by Alain Plantec. It was further improved by S. Ducasse and S. Denier who got great fun in designing it. The basic principle is the following one: rename all methods of a class: XXX -> NOTSENTXXX. but before install #doesNotUnderstand: and #recompileNotSent:, so that, for a not understood message named YYY, if NOTSENTYYY exists, then, NOTSENTYYY is dynamically renamed YYY and then, message is resent. Deals also with superclass methods that were hidden (and could be accessible due to the previous strategy), by recompiling them locally with the default behavior to recompile themselves into the NOTSEND associated one when executed. 1 March 2009 Known Issues: ---------------- - freezes when applied on Morph Stef

[Pharo-project] Preference refactoring again
by Alain Plantec March 2, 2009

March 2, 2009

Hi all, joined Zoo package is a attempt to translate in code what we discussed here before about preference refactoring. The framework is made of 3 classes: PreferenceCollector, PreferenceDefinition and PreferenceValue. In Zoo there are also 2 classes for testing: PrefProvider and PrefChangeListener. PrefProvider class declares some preferences and PrefChangeListener is here to test preference change notification. PrefChangeListener>>initialize super initialize. PreferenceCollector whenChanged: #gradientButtonLook inClass: PrefProvider notify: self using: #gradientButtonLookIsNow: . PreferenceCollector whenChanged: #gradientButtonLook inClass: PrefProvider notify: self using: #gradientLook: PrefChangeListener class>>test "self test" PrefChangeListener new inspect. PrefProvider gradientButtonLook: PrefProvider gradientButtonLook value not. PrefProvider gradientButtonLook: PrefProvider gradientButtonLook value not. PrefProvider gradientButtonLook: PrefProvider gradientButtonLook value not. From PreferenceCollector comment: -------------------------------------- A PreferenceCollector automatically collects all preferences. A preference is represented by a PreferenceDefinition. All PreferenceDefinition are stored in the preferences instance variable. Instance Variables preferences: OrderedCollection of PreferenceDefinition preferences - contains all PreferenceDefinition which are automatically built from pragma found in preference getters ADDING A PREFERENCE PreferenceCollector makes use of the SystemChangeNotifier in order to automate the adding, the removing and the updating of preferences. See #PreferenceCollector>>event: to see how preferences update is implemented. Editing a new method with a preference pragma or inserting a preference pragma in an existing method are the two ways for preference definition adding. The only way to remove a preference definition is to remove the corresponding method. Example of a "blackAndWhite" preference. Methods below are defined by the preference provider APreferencePrivider class. Note that the value stored in BlackAndWhite class variable is an instance of PreferenceValue. In this example, the default value is directly given with the pragma: ------------- APreferencePrivider class>>blackAndWhite <preference: 'Use black and white' type: #Boolean set: #blackAndWhite: defaultValue: false description: 'Use black and white'> ^ BlackAndWhite ifNil: [BlackAndWhite := PreferenceValue value: false location: self selector: #blackAndWhite] APreferencePrivider class>>blackAndWhite: aBoolean self blackAndWhite value: aBoolean ------------- If a default value can't be specified in the pragma, another way consists in using a selector which represents the message to send to the class in order to get the default value: ------------- APreferencePrivider class>>standardFont <preference: 'The default system font' type: #LogicalFont set: #standardFont: default: #defaultStandardFont description: 'The default system font'> ^ StandardFont ifNil: [StandardFont := PreferenceValue value: self defaultStandardFont location: self selector: #standardFont] APreferencePrivider class>>standardFont: aFont self standardFont value: aFont APreferencePrivider class>>defaultStandardFont ^ LogicalFont familyName: 'Arial' fallbackFamilyNames: nil pointSize: 12 stretchValue: 5 weightValue: 400 slantValue: 0 ------------- LISTENING TO A PREFERENCE VALUE CHANGE Any object can register itself as a preference value change listener. See #PreferenceCollector class>>whenChanged: inClass:notify:using:. Each time a preference value is changed, #preference: inClass:changedWith: is sent to the PreferenceCollector class. Example of code a listener can implement in order to be notified each time a gradientButtonLook preference defined by a PrefProvider class is changed. In this example, the listener ask to be notified by a send of #gradientButtonLookIsNow: message. The argument given to gradientButtonLookIsNow: is the new preference value. ------------- .... PreferenceCollector whenChanged: #gradientButtonLook inClass: PrefProvider notify: self using: #gradientButtonLookIsNow:. .... ------------- What do you think ? cheers Alain

[Pharo-project] What are the ERROR messages in the Transcript Window in 10243?
by Rob Rothwell March 2, 2009

March 2, 2009

Maybe I just wasn't able to follow the conversation properly, but if you open a Transcript in 10243 (dev) and, say, search for the class "Morph," you will get: ERROR: Morph class>>overridesSelectors ERROR: Morph class>>superSenderSelectors ERROR: Morph class>>conflictsSelectors ERROR: Morph class>>overridesSelectors ERROR: Morph class>>superSenderSelectors ERROR: Morph class>>conflictsSelectors In fact, anytime you do anything (save a method, etc...), it seems you get these messages, and yet things seem to be working.
