[Pharo-project] Refactoring Questions
by Camillo Bruni May 28, 2012

May 28, 2012

after having a look with ben at the current refactoring implementation in Nautilus we found that the "Extract into temporary" refactoring is most of the time not that useful. I wonder wether it would make sense to loosen the requirements on conserving behavior... consider the following example where we extract "self foo" into the temporary "tmp": =========================================== foo ^ self foo even ifTrue: [ self foo * 2 ] ifFalse: [ self foo / 2 ] actual result ============================= foo | tmp | tmp := self foo. ^ tmp even ifTrue: [ self foo * 2 ] ifFalse: [ self foo / 2 ] proposed result =========================== foo | tmp | tmp := self foo. ^ tmp even ifTrue: [ tmp * 2 ] ifFalse: [ tmp / 2 ] =========================================== note that the proposed solution is not side-effect free. However the given refactoring hardly makes ever sense, since this action can be easily done manually in less time. given that you first have to find the proper menu-item. best cami

[Pharo-project] building and installing a morph in the background
by Tudor Girba May 27, 2012

May 27, 2012

Hi, I am trying to build a complex morph and install it in another morph in a background process such that it does not impact the rest of the user interface. After a discussion with Igor, I got to the code below (similar to what can be found in CodeAnnotationPane). However, it still does not seem to have the desired effect as the main ui still appears to be blocked. Can anyone see any problem with the code? The code can be found in the latest version of Glamour. Cheers, Doru GLMWatcherWindow>>addContent: aBlockWhoseValueReturnsAMorph | newMorph | "if we are still rendering some contents for another watcher, we stop and replace with the current request" process ifNotNil: [ process terminate ]. process := nil. process := [ WorldState addDeferredUIMessage: [ newMorph := aBlockWhoseValueReturnsAMorph value. self contentsMorph removeAllMorphs; addMorph: newMorph fullFrame: (LayoutFrame fractions: (0@0 corner: 1@1)) ] ] newProcess. process priority: Processor userBackgroundPriority. process resume -- www.tudorgirba.com "Problem solving should be focused on describing the problem in a way that makes the solution obvious."

[Pharo-project] Halt using UnhandledError: bad idea
by Igor Stasenko May 27, 2012

May 27, 2012

hi, i just discovered that Halt signals the exception as unhandled one.. which, in own turn makes announcers who using on:fork: to _fork_ the process, so when debugger opens you don't see who sent the announcement since the bottom stack frame is #on:fork: Now if you change Halt>>defaultAction ^ UIManager default unhandledErrorDefaultAction: self " UnhandledError signalForException: self " things is much better, since i can see whole stack... I find it strange, why to open debugger with halt, one must signal other exception (which is UnhandledError)? UnhandledError ~~ Halt!!! -- Best regards, Igor Stasenko.

[Pharo-project] VM problem?
by Fabrizio Perin May 27, 2012

May 27, 2012

Hi, I'm using last Moose build on top of CogVM 2550 and each time I click on a method an error pops up (see the attachment). The same problem I have it with older builds of Moose but I don't have any problem if I open the same image with Cog VM 2540 or CogVM from the Pharo web site. I'm on Mac os 10.7.4 and the image is: Pharo1.4 Latest update: #14438 Cheers, Fabrizio
