One way is to -bring up the morphic halo (shift-alt on mac) and click until you have the pluggable button selected. -click the debug halo (spanner) and say inspect morph. -see the actionSelector is openRepository -browse implementors, there is only one -correlate this with the model -toggle break on entry in the method view -press the button cheers Mike

little fix for Slice

by StÃ©phane Ducasse

hi all Does any of you want to help? with a little exercise? It would be nice to help the user to provide coherent slice name I suggest SLICE-number-title title with only alphanumberical-characters any taker? because this would be cool to get another step forward http://code.google.com/p/pharo/issues/detail?id=2478 Stef

[GSoC] Coding started yesterday!

by Mariano Martinez Peck

Hi everybody. First, let me apologize for the multiple cross post. I think it is good to show the Smalltalk community periodically the status of GSoC. The good news in this case is that yesterday the students started to code! This was one of the GSoC deadlines that you can read in http://gsoc2010.esug.org/ and in http://socghop.appspot.com/document/show/gsoc_program/google/gsoc2010/faqs#… . Last two weeks or so, students have been talking and discussing with their mentors, reading and investigating about the projects. Some students already started to code before. But yesterday was the official day to start to code. For those that didn't know, we got not 5 but 6 projects. We asked more and they gave us one more ;) Once again, if you want to look at the 6 selected projects, see http://gsoc2010.esug.org/projects We already told students to ask in case of problems or questions to their mentors but also to the community (trough the mailing list). So, let's help them! Students: don't be shy. Ask! ;) Good luck to all students and enjoy this wonderful opportunity you have. Now we are in the best part of the program! Best regards, Mariano Martinez Peck GSoC admin gsoc-admin(a)esug.org http://gsoc2010.esug.org

Do you really need to create a meta? If not , then you can do just: newClass := Rectangle clone. newClass superclass: Rectangle; organization: nil; methodDict: MethodDictionary new.

What's the correct way to create anonymous subclasses in Pharo?

by Joachim Geidel

Hi everybody, I am attempting to create subclasses of existing classes at runtime. They must not be in their superclass' list of subclasses, because they have to be garbage collected when they are no longer needed. This is what I tried to create such a class in Pharo 1.0: newMeta := (Metaclass new) superclass: Rectangle class methodDictionary: MethodDictionary new format: Rectangle class format; yourself. newClass := (newMeta new) superclass: Rectangle methodDictionary: MethodDictionary new format: Rectangle format; setName: #MyRectangle; yourself. newClass new class == newClass "--> false" The result of "newClass new" seems to be an instance of Rectangle, not of newClass. The test at the end of the code snippet answers false. When I compile a new method in newClass and install it in newClass' methodDictionary, an instance will not understand a message with the method's selector. Almost the same code will do what I want in VisualWorks: | newMeta newClass | newMeta := (Metaclass new) superclass: Rectangle class; methodDictionary: MethodDictionary new; setInstanceFormat: Rectangle class format; yourself. newClass := (newMeta new) superclass: Rectangle; methodDictionary: MethodDictionary new; setInstanceFormat: Rectangle format; setName: #MyRectangle; yourself. newClass new class == newClass "--> true" Does anybody have an idea what the problem is and what can be done to circumvent it? Thanks in advance! Joachim Geidel

[BetaTesting] [ANN] Pharo-1.1-11367-Beta1dev10.05.1

by Mariano Martinez Peck

Hi Pharaoers. I am pleased to announce the first Pharo 1.1 beta based on PharoCore-1.1-11367-Beta. It is the first time we build a Pharo 1.1 dev image with PharoCore 1.1 so the image may be not 100% stable. However, we think it is good to release it so that people can start to test it, load their own packages, adapt them, etc. We would like to receive feedback about it. It (yet) has failing and error tests. The main changes with Pharo 1.0 is that of course, it is based on a PharoCore 1.1 with all that it means. We started to write down some of the actions done in PharoCore 1.1. The list so far can be found here: http://code.google.com/p/pharo/wiki/ActionsInPharoOneDotOne Of course, for the stable releae of Pharo 1.1 we will do a clear list in the website as we did for 1.0. Regarding the included packages in 1.1 we added ScriptManager (a tool to manage and persist workspaces), ProfStefBrowser, ArchiveViewer, MethodWrappers and ObjectMetaTools (which includes things like ProtocolCatcher, ObjectTracer, ObjectViewer, etc). Another difference is the font. In Pharo 1.0 we used TrueType fonts by default. In Pharo 1.1 we use StrikeFonts (no need of TrueType plugin, netiher to have the fonts). However, of course, you can disable StrikeFonts and put TrueType like in 1.0. That's all. We would really appreciate you use it, test it, report issues, provide fixes, etc. It is important also that you start to use your own packages/applications. There have been several changes in 1.1 that may require change in your code. Ahh if you want to create the image yourself, check as usually the installScript.st file to see how to do it. Actually, you can just take a PharoCore-1.1-11367-Beta image and evaluate (the same procedure as 1.0): Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPharo'; load. ((Smalltalk at: #ConfigurationOfPharo) project version: '1.1-beta1.10517') load.

Flushing the VM method cache?

by Joachim Geidel

Hello all, The software I am working on generates classes on the fly, and discards those classes when they are no longer needed. The class library is cross-platform, i.e. it exists for Dolphin and VisualWorks, and I am currently porting it to Pharo. In Dolphin, it is necessary to flush the VM's method cache after discarding all the dynamically generated classes, because the method cache holds references to the classes which prevent them from being garbage collected. For VisualWorks, I have adopted this, although I am not quite sure if it's actually needed there. In the Pharo 1.0 image, I haven't found a method for flushing the VM's method cache in one go, there only seems to be Behavior>>flushCache. What I would like to know is: - Does the VM method cache of the Squeak VM hold references to classes which prevent an obsolete class from being garbage collected? If this is not the case, I don't need to flush anything. - If flushing the cache is advisable, is Behavior>>flushCache the only way to do this? I would have to pick up all the obsolete classes and iterate over them in that case. Thanks in advance! Joachim Geidel

Re: [Pharo-users] Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

by RickT

Thanks for the great response! I am not only a newbie to Smalltalk but also to any sort of network programming. I guess my exposure to 'ping' on other systems was always the ICMP flavor; so I was surprised by this implementation. As Mariano pointed out, the source code in Pharo1.0 indicates port 7: tcpPort := 7. "7 = echo port, 13 = time port, 19 = character generator port" It seems to me that a ping: method should be the ICMP kind, and a ping:port: method should be for the TCP variety. I presume an echo server could be run on ports other than 7 or 10, depending on preference. So maybe the port should be designated by the caller, and not hard-coded into the class method. I see the other reasoning from your response. Thanks again for clarifying this (and educating me). -- View this message in context: http://forum.world.st/Newbie-Does-Socket-ping-addr-work-in-Pharo3-11-8-tp22… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Alas.

So you can try the method #pingPortsOn: hostName which does: pingPortsOn: hostName "Attempt to connect to a set of well-known sockets on the given host, and answer the names of the available ports." "Socket pingPortsOn: 'www.disney.com'" ^ Socket pingPorts: #(7 13 19 21 23 25 80 110 119) on: hostName timeOutSecs: 20 ;) Mariano > > Here's the method comment, emphasis added > > "Ping the given host.

The DOS and Unix ping utilities send an *ICMP* echo request packet and expects an echo response. This is normally handled by the protocol stack itself. The Pharo #ping: method makes a *TCP* connection to port 10 (echo service) on the destination machine. If there's no server listening on that port, the connection will fail. Here's the method comment, emphasis added "Ping the given host. Useful for checking network connectivity. *The host must be running a TCP echo server*."

Accentuate Characters

by Adrien BARREAU

Hello, I want to compose accentuate character in Pharo, but I don't know how I can do that. I saw in Visual Works I can write this kind of things : $e composeDiacritical: (Character diacriticalNamed: #acute). That returns $Ã©. But, I don't find a way to do that in Pharo. Does somebody have an idea ? :) A.B. _________________________________________________________________ Vous voulez regarder la TV directement depuis votre PC ?

I know that, but I was just pointing out that if I change the base class and commit while your code is loaded, I publish unwillingly your trait. So, when your code is loaded I have to be careful to first remove the trait and only afterwards publish my change. This is a severe limitation and it stems from the Trait definition being tightly coupled with the class definition (both in the model and in the browser). Cheers, Doru >> 2.

Thanks ron for the offer as you can see in http://code.google.com/p/pharo/issues/detail?id=1884 we got a bit burned by the status of the network code. So if you can try some expressions with the latest unstable 1.1 it would help us to know if we should apply the rollback fix.

Hi Mariano, Your debugging efforts match what I was finding. I was originally having problems with Socket>>connect: , which kept failing. So I thought I would just try the most minimal thing, ping. There may be problems with Socket class in general.
