To close all the games opened you can evaluate: LOGame allInstances do: [:i | i delete]. I'm currently working on a screencast for the LightsOut exercise in PBE. Should be out in a couple of days.

I'm going through the book too. If your problem is that you can't close the game then here's how... First, get halos around the upper-left cell and close it; it should turn blue. Then get halos around the cell that turned blue (which should be labeled 'LOGame') and then you can close the game.

Re: [Pharo-users] How to detect an inactive image?

by Michael Roberts

I guess you would need a way to sample a set of processes that were executing what you considered activity; and ignore the ones that are not. With some data, e.g assuming they block on semaphore when idle, or terminate when idle, perhaps you can make a decision. I haven't looked, but was imagining some of the profiler framework might help because I thought it did process sampling. cheers, Mike On Sat, Oct 30, 2010 at 11:10 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > IF you get some answers I;'m interested to know it because we are thinking about what is a VM API to monitor them. > > >> At the moment I have several projects in parallel.

Another Halo Question (complete newbie)

by James Ashley

How-dee! I'm working my way through PBE (no, I've been too broke lately to buy a copy yet *blush*, but I will) and a few other smalltalk tutorials. I've read the documents about getting halos activated in the first place. I'm on linux, where alt-shift middle-click (I'm still trying to get the button colors down) generally works. In the lights out sample, it doesn't. I can ctrl-shift "left" click, get a giant menu, and select "Add Halo." That puts a halo around the individual cell. If I close it, it disappears and shows a blue background (which I'm starting to suspect is a default for morphics...is that close?). If I jump back through the "Add Halo" hoops on that background, or actually manage to click on the border, I just get what seems to be halos for the desktop (system? background? It's always frustrating to start learning a new system and not know the terminology...then again, that's part of the fun). I've been able to close the morphic by adding a "self owner delete" mouse down handler to the cells, then commenting it out until I need it. But it's more than a little painful. I spent about two hours today googling for variations on "morphics decorated frames", but the results I got suggested that I'm not even in the ballpark. I'm sorry if I missed an FAQ or didn't dig far enough back in the mailing list archives. Thanks in advance, James

How to detect an inactive image?

by Norbert Hartl

At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser. For persistency I use piers image based persistency. But I don't want to have all of the images run all the time. I would like to shutdown images if they aren't accessed for some time. I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside. What is a good measure of activity inside the image? thanks, Norbert

Activating Halos around morphs

I'm new to Pharo and I'm going through the PBE book (yep, I bought it). I'm using the image that goes with the book on Windows XP Pro. I can't get halos around any morphs and I don't see a setting in the Preferences browser (I notice this was changed to Settings in later releases). I tried evaluating Preferences enable: #halosEnabled but it had no effect. Interestingly, I can get halos around the the World menu with alt+left-click, but once I pin it, I can no longer get the halos. What am I missing? Daniel Klein

[ANN] Continue working in SimpleLogger

by Mariano Martinez Peck

Hi guys (German). Today I needed to add some real log to something I am developing and I found that SimpleLogger missed those functionalities I was needing. So...I implemented them. It is 3 hours effort, so don't expect too much. But I just wanted to shared with you in case you need it. What I did basically is to define SimpleLogger like the public API. But then, this class delegates to a LoggerStrategy. I created the following implementations: TranscriptLoggerStrategy, NullLoggerStrategy, FileLoggerStrategy and FixesFileNameLoggerStrategy. In addition, I created a superclass for them, marking the API with SimpleLogger. This class is LoggerStrategy. So, now you can: - Enable and disable easily the logging (thanks to NullLoggerStrategy). - Change on runtime WHERE or HOW to log (just change the strategy). - Be able to write into a File, a Transcript, a FixedFileName, or nothing. - Extend to you own strategy (FileAppendLoggerStrategy?? SocketLoggerStrategy? etc...) I did these changes today morning so I didn't have time to write tests nor class comments. However, I wrote some class side example methods in SimpleLogger. Finally, for my own projects I want: - to use a FixedFileName (very similar to the way PharoDebug.log is used). - to only do "self log:" in my classes. The solution I did is that somewhere (maybe in a class of your project or maybe in a special class that holds this) in a class side variable I hold a Singleton with the Logger. So that you can always do for example: MyAppLogger logger log: 'zaraza'. And finally, I implemented Object >> log: (with category *MyAppPackage) log: anObject MyAppLogger logger log: anObject. With this, anywhere in the classes of my app I can do: self log: 'something'. The code is temporally commited in http://www.squeaksource.com/Marea German: if you think I should commit directly to SimpleLogger repo, just let me know. In addition, be completely free to change it as you want and commit it there too. Cheers mariano

Decompiling method body returns as block?

by HernÃ¡n Morales Durand

Hi list, I'm using Pharo1.1rc2 #11400 and I want to extract the body part (the String without the selector) of a CompiledMethod, but I'm getting a BlockNode after sending #body and a MNU afterwards. This is what I do aCompiledMethod decompileWithTemps ---> a BytecodeAgnosticMethodNode which is displayed like: 'renderContentOn: aRenderer aRenderer form id: ''horizontalForm''; with: [aRenderer fieldSet: [ ... blablabla ]]' and is ok. Then aCompiledMethod decompileWithTemps body ---> a BlockNode displayed as: {[:aRenderer | aRenderer form id: 'horizontalForm'; with: [aRenderer fieldSet: [... blablabla]]]} I've expected the code string (sending #decompileString) without "[:aRenderer |" part (used to work that way). The thing is if I send #code to the BlockNode I get a "MessageNotUnderstood: CascadeNode>>code". I'd appreciate any hint to solve this.

Re: [Pharo-users] Difference between Set and HashedCollection

by Andres Valloud

Generally speaking, the storage strategy should be dissociated from the hashed functionality that is to be provided. In other words, open addressing linear probing and hash buckets should be swappable under set (or dictionary, etc).

HashedCollection is an abstract base class, which contains common behavior for all hash-based collections, including Set, Dictionary etc. On 18 October 2010 13:04, Benjamin Van Ryseghem <benjamin.vanryseghem(a)gmail.com> wrote: > I was looking in Pharo sources and I do not understand the difference > between Set and HashedCollection which both seems to work the same way. > > > Benjamin > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > > -- Best regards, Igor Stasenko AKA sig.

Difference between Set and HashedCollection

by Benjamin Van Ryseghem

I was looking in Pharo sources and I do not understand the difference between Set and HashedCollection which both seems to work the same way. Benjamin
