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

FFI Problems in Pharo 1.1 'Callout mechanism not available'

by BraveSirRobin

I'm having intermittent problems with FFI in Pharo 1.1. I often get my image to the point where I can only get the error 'Callout mechanism not available' whenever I call a DLL function. These functions have previously worked perfectly but then stop working for some reason. Anyone know what causes this and what the fix/workaround is ? The only solution I've found so far is to save my packages and load them into a new image which is a bit time consuming. BTW, I'm running under Windows 7, 32-bit. -- View this message in context: http://forum.world.st/FFI-Problems-in-Pharo-1-1-Callout-mechanism-not-avail… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Simple OO smaltalk question

by Tony Giaccone

I'm new to Smalltalk and come from the java world and am looking for a bit of help on how something should be implemented. Assume I have a Person class and that there are three subclasses of that class Admin, Teacher, Student. I also have a class called UserManager I want to implement a method on UserManger>> class firstPageForUser: user This method looks at the class of the user and returns an initial page for each user after log in. I have this method implmented: Person>>class firstPageForUser ^nil Now on the UserManager clas>> firstPageForUser: user (user isKindOf: Person ) ifTrue: [returnPage := ( (user class) firstPageForUser) ]. Which as I'm sure most of you realize doesn't work. I'm not sure how to structure the call so that the right message gets sent to the class. My understanding is that even though the subclasses don't implement this method yet, that the method should be passed up the class tree till it finds the method in Person. However, I also know that the syntax for the method I've written isn't correct. What I want to do is make the call on the class for each subclass. I could do the same thing this way, right, but this seems more verbose and ugly then it has to be. (user isKindOf: RSPerson ) ifTrue: [returnPage := (RSPerson firstPageForUserClass) ]. (user isKindOf: RSAdmin ) ifTrue: [returnPage := (RSAdmin firstPageForUserClass) ]. (user isKindOf: RSTeacher ) ifTrue: [returnPage := (RSTeacher firstPageForUserClass) ]. (user isKindOf: RSStudent ) ifTrue: [returnPage := (RSStudent firstPageForUserClass) ]. ^returnPage

Re: [Pharo-users] Consuming delimiters in PetitParser

by Lukas Renggli

Hi HernÃ¡n, I am not really sure what you want to express with the following parser? ( #digit asParser plus flatten plusLazy: $| asParser ) Having multiple quantifications (#optional, #plus, #plusLazy:, #plusGreedy:, #star, #starLazy:, #plusGreedy:, #times:, #min:, #min:max:) in a row does not really make sense and seems likely a bug. In your example the #plusLazy: will only be able to consume the receiver once. As you can read in the method comment of #plusLazy: the argument is not consumed, thus whatever follows will have to consume it. If you want to accept multiple numbers like in >gi|123|456|789|abc then you should likely use #separatedBy: like in p := ( $> asParser , 'gi' asParser , $| asParser , ( #digit asParser plus flatten separatedBy: $| asParser ) , ($| asParser) , ( (#letter asParser / #digit asParser / #space asParser / #punctuation asParser ) asParser plus flatten ) ) end. If you just want one number then the simpler p := ( $> asParser , 'gi' asParser , $| asParser , ( #digit asParser plus flatten ) , ($| asParser) , ( (#letter asParser / #digit asParser / #space asParser / #punctuation asParser ) asParser plus flatten ) ) end. will do.

Re: [Pharo-users] Hard crash when teaching

by Johan Fabry

So I was a bit annoyed about this behavior, because I still think it is a cool demo to show in class. So I had a poke around the system (Thanks Igor for pointing me in the right direction). What happens is that ImageMorph>>image: does at some point super extent: 2 * self borderWidth + image extent. where self borderWidth is an int. Now wait a minute, what does it mean, conceptually to sum an int with a point? I have no idea. So what are we doing here? Computing the extent considering the extra border size we have. So what we want to do is sum 2 points, now that does makes sense. super extent: (2 * self borderWidth) asPoint + image extent. With this fix, I can turn of coercion for Integers without any problem, fixing the original issue. Plus the behavior of ImageMorph>>image: is the same, as far as I can tell. Bonus: conceptually cleaner, more robust system, and the ability to do funky demos in class. See, I can do brain surgery, just not at the same time as teaching :-) (Marcus: this fix attached to the bug report, even though it is closed, just in case you consider it worthwhile ...)

this is not beacuse self surgery is good when you cut your nails the morning in your bathroom that operating your brain is not a stupid idea.

But of course, i wouldn't never expect from system to keep working stable & normally, when you changing something as basic as Integer>>+. But there is a bright side: such things could be used to detect low-quality code (or code, which intentionally doing coercions ;)... For instance, i often type: 100/200 if you evaluate that, you'll get a Fraction as result: (1/2) but i want the answer to be Float, so i type: 100/200 asFloat and here, when you change the Integer>>#/ to throw error instead of coercing receiver, i won't be able to use it anymore, and will be forced to write: 100 asFloat / 200 asFloat > -- > Johan Fabry > jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry > PLEIAD Lab - Computer Science Department (DCC) - University of Chile > > > > > _______________________________________________ > 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.

I didn't experienced the hard crash in pharo image. What i got instead, is an error, printed in emergency console saying that it unable to handle the system error .. the culprit is in ImageMorph>>image: while somehow relying on correct behavior of Integer>>+ and ImageMorph obviously used by Morphic rendering. So, its not crashing. Image is still responsible. You just broken UI with it: a toolbuilder, when creating a new Error popup window, also creates and initializing an ImageMorph as a submorph. And since it fails with error, the error-handling layer treats this as failure to handle error and thus, it switching to emergency console. Btw, there was a good chances, that even an emergency console could be broken because of such change. > -- > Johan Fabry > jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry > PLEIAD Lab - Computer Science Department (DCC) - University of Chile > > > > > _______________________________________________ > 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.

Hard crash when teaching

by Johan Fabry

Always fun when you want to show the students that everything can be changed in Smalltalk ... Inclusive the behavior of Integer>>+ Inclusive when the current behavior does strange things with the second argument when it is not a number (instead of simply throwing an error), e.g what happens in 1 + 'foo' Inclusive when you are debugging said expression. Apparantly that was too much to ask :-( Hard crash of the image :-( :-( Reported as issue http://code.google.com/p/pharo/issues/detail?id=3072 -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

Re: [Pharo-users] I'm trying to call markdown as an external process

by David T. Lewis

Hi Pat, I'm not familiar with Markdown, but it sounds like you want to run an external process (Markdown), write to its standard input from Smalltalk, and read its standard input back into Smalltalk. Try using class PipeableOSProcess for this. There are some examples in the class side methods that show how it works. PipeableOSProcess works at a higher level than the classes in OSProcess, and it will handle the issues of connecting the external process to your image through pipes. Be careful about reading the output from your external Markdown process. Pipes by default work in blocking mode, see #setNonblocking to change this. If you do a read on the output of a blocking pipe, and if there is no data available, your VM will block and your image will be locked up. So save your image frequently until you get the details worked out ;) HTH, Dave On Thu, Oct 07, 2010 at 01:00:24AM +0200, Mariano Martinez Peck wrote: > David may help you. > > Cheers > > Mariano > > On Wed, Oct 6, 2010 at 2:27 AM, Pat Maddox <patmaddox(a)me.com> wrote: > > > On Oct 5, 2010, at 5:05 PM, Pat Maddox wrote: > > > > > I'm trying to do something which (I think) is very simple: I just want to > > run a line of text through Markdown and get the output. > > > > > > I've spent all day reading through the code for OSProcess and > > CommandShell.
