Re: [Pharo-project] some patterns I would like to **kill**

by Schwab,Wilhelm K

If I understand you, you took things normally stored in instance variables, and (redundantly?) stored them as properties, right? ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Igor Stasenko [siguctua(a)gmail.com] Sent: Saturday, October 23, 2010 10:47 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] some patterns I would like to **kill** On 23 October 2010 21:47, Schwab,Wilhelm K <bschwab(a)anest.ufl.edu> wrote: > Hey, I want some credit here - for coming to Squeak's possible defense :) > > All I am saying is that there is a possible space/speed tradeoff with a twist. There was a fair amount written about these decisions, which is why I know anything at all about them. Adding an instance variable for a rarely used sub-morph of a widely-instantiated morph might be an opportunity to fail to learn from history. Most likely, the patterns Stef has noticed are simply mis-uses of sparse storage. The best way to proceed would be to find an example of it that has many instances in the image, profile, fix, and profile again to see if the fix hurts performance (or perhaps helps it). The usual caveats about benchmarking being really hard to do well apply, of course. > I did some experiment(s) with Morphic, placing many morph aspects into properties dictioary (such as color, border, borderwidth etc), and these values are used in rendering all the time.

Morphs were designed to be usable in large numbers, and one might argue (playing Devil's Advocate here) that lookups are cheaper than the additional gc load. An instance variable could also cache stale information. Of course, for something that is accessed frequently, an instance variable avoids the lookup and I agree that it is cleaner and easier to read. >>> >>> Bill >>> >>> >>> >>> ________________________________________ >>> From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of stephane ducasse [stephane.ducasse(a)free.fr] >>> Sent: Thursday, October 21, 2010 4:47 PM >>> To: Pharo Development >>> Subject: [Pharo-project] some patterns I would like to **kill** >>> >>> Hi >>> >>> I was reading Pluggable and friends >>> I identified some patterns. >>> >>> >>> The respondsTo plague >>> Examples: >>> >>> color := self fillStyle asColor. >>> (self labelMorph respondsTo: #enabled:) >>> ifTrue: [self labelMorph enabled: self enabled]. >>> (self labelMorph respondsTo: #interactionState:) >>> ifTrue: [self labelMorph interactionState: self interactionState] >>> >>> (self labelMorph respondsTo: #enabled:) ifTrue: [ >>> self labelMorph enabled: aBoolean]. >>> >>> (self enabled not and: [self label isMorph and: [(self label respondsTo: #enabled:) not]]) >>> >>> >>> by construction a labelObject should be a morph and it should answer enabled: and the case where this is not the case should be fixed. >>> >>> >>> Using submorphs to avoid one single inst var makes code quite ugly to read: >>> >>> >>> labelMorph >>> "Answer the actual label morph." >>> >>> self hasSubmorphs ifFalse: [^nil]. >>> self firstSubmorph hasSubmorphs ifFalse: [^nil]. >>> ^self firstSubmorph firstSubmorph >>> >>> >>> >>> >>> >>> _______________________________________________ >>> Pharo-project mailing list >>> Pharo-project(a)lists.gforge.inria.fr >>> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >>> >>> _______________________________________________ >>> Pharo-project mailing list >>> Pharo-project(a)lists.gforge.inria.fr >>> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >> >> >> _______________________________________________ >> Pharo-project mailing list >> Pharo-project(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >> >> _______________________________________________ >> Pharo-project mailing list >> Pharo-project(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >> > > > > -- > Best regards, > Igor Stasenko AKA sig. > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig. _______________________________________________ Pharo-project mailing list Pharo-project(a)lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

[Pharo-project] Learning on Sockets

by laurent laffont

Hi, I want to record a screencast on basic networking and also explore this idea: http://forum.world.st/Community-in-the-IDE-tp2543540p2543540.html Do you have some links on documentation and/or good code to look at ? I'm searching for best practices / modelizations to write a chat server and client. Actually I've read and tried those: http://book.pharo-project.org/book/networking/Socket http://wiki.squeak.org/squeak/325 Cheers, Laurent Laffont Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/
