Easy way to write a proxy?
by Alexandre Bergel March 3, 2015

March 3, 2015

Hi! I have a near-to-be naive question. Maybe there is something obvious, but I cannot see it. Consider the following implementation of a proxy: -=-=-=-=-=-=-=-=-=-=-=-= Object subclass: #MyProxy instanceVariableNames: 'object'. MyProxy >> object: anObject object := anObject MyProxy >> doesNotUnderstand: aMessage ^ object perform: aMessage selector withArguments: aMessage arguments Object >> wrap self becomeForward: (MyProxy new object: self; yourself) -=-=-=-=-=-=-=-=-=-=-=-= The problem is with wrap. After the becomeForward:, MyProxy has itself in the object variable. Even self is apparently subject to the #become. It means that the following code loop indefinitely -=-=-=-=-=-=-=-=-=-=-=-= d := Dictionary new. d wrap. d add: #foo -> 10 -=-=-=-=-=-=-=-=-=-=-=-= I know there is Marianoâs library to write proxy. But I still wondering whether this could be done simply. Any idea how to simply create a proxy? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Keyboard Event Weirdness
by Sean P. DeNigris March 2, 2015

March 2, 2015

I put the following halt in HandMorph>>#handleEvent: anEvent isKeyboard ifTrue: [Transcript show: anEvent printString, ' keyChar: ', anEvent keyCharacter asString, ' keyValue: ', anEvent keyValue asString; cr]. Then I typed 'hi' in a Workspace and hit Cmd+a. Look at the weird Transcript output... [keyDown ''] keyChar: keyValue: 4 [keystroke 'h'] keyChar: h keyValue: 104 [keyUp ''] keyChar: keyValue: 4 [keyDown ''] keyChar: keyValue: 34 [keystroke 'i'] keyChar: i keyValue: 105 [keyUp ''] keyChar: keyValue: 34 [keyDown '<Cmd->'] keyChar: keyValue: 0 [keystroke '<Cmd-a>'] keyChar: a keyValue: 97 [keyUp '<Cmd->'] keyChar: keyValue: 0 It seems the keyUp/Downs do not have the correct charCode and the keyValue is different than the keystroke for the same key. What's going on here? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Keyboard-Event-Weirdness-tp4737056.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Visual Debugger Feedback for Resumable Exceptions
by Sean P. DeNigris March 2, 2015

March 2, 2015

I was creating a class with an empty package name. When the debugger appeared, stating that "The Category should not be empty' [1], I thought I would not be able to use that package name. But, in fact, as I found out later, the exception is resumable, and clicking 'Proceed' created the class in the '' package. It might be nice to make it obvious to the user when exceptions are resumable. If, for example, the "Proceed" button said "Resume", I might have realized right away that there was value in continuing execution. [1] OT: This is probably not the best message for a resumable warning. How about something like "Are you sure you want to use an empty category?" ----- Cheers, Sean -- View this message in context: http://forum.world.st/Visual-Debugger-Feedback-for-Resumable-Exceptions-tp4… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

ChangesBrowser should not roll own dialog (was 13017 Class renaming does not update textual class definition)
by Sean P. DeNigris March 2, 2015

March 2, 2015

Issue 15030: ChangesBrowser should not roll own dialog Since Spec already provides a dialog wrapper, the ChangesBrowser should use it. Fix in inbox: SLICE-Issue-15030-ChangesBrowser-should-not-roll-own-dialog-SeanDeNigris.1 - Replace hand-rolled dialog functionality with Spec's #openDialogWithSpec. The 'Accept' button is now labeled 'Okay'. It could be changed, but I don't see the point of the added complexity. - Fix senders/users ----- Cheers, Sean -- View this message in context: http://forum.world.st/ChangesBrowser-should-not-roll-own-dialog-was-13017-C… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
