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

by RickT

I bought the Seaside book and am reading it and PBE. (I also stumbled upon the other book in progress by reading one of your postings.) In Pharo1.0 image, when I defined the class useOldNetwork: message, it did not understand the UseOldNetwork variable to be assigned aBoolean, so I had to declare the class variable. It did not help ping work either. Does the Socket>>ping: work for you? Or am I the only one breaking on this?

Actually that was for breaking encapsulation as NetNameResolver does not have a setter for such class variable.

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

by RickT

I am loving the Smalltalk environment and language very much, thanks! (But I remain an ignorant newbie nonetheless.) I hope to later explore Seaside with Pharo as well. To my problem: With the Pharo 1.0 image, the classVarNamed:put: message was not understood. (Same for Linux version of Pharo 1.0). With the Pharo 1.1 image you linked me to, the message was understood, but had no effect. I still cannot get Socket>>ping: to work; it always times out. And yes, I meant the OS command window ping worked. For Windows XP it is what you would call the DOS command line. I also downloaded and tried the Pharo1.0 in my VirtualBox VM running Ubuntu. I have the same problem: I can ping localhost from the Linux command line, but Pharo 1.0 ping always times out. (I am running on a Dell M90 Precision laptop. FWIW) Thanks very much for your help.

Where you can successfully ping ? what's is a command window? do you mean DOS or somehow outside Pharo? Can you try the same after evaluating: NetNameResolver classVarNamed: 'UseOldNetwork' put: true Can you try also the same but using a PharoCore 1.1 image (you can use the same VM): https://gforge.inria.fr/frs/download.php/26995/PharoCore-1.1-11357-UNSTABLE… Thanks!

Anyone wants to put style to the welcome workspace?

by Mariano Martinez Peck

Hi folks. Any volunteer to make the welcome workspace nicer? Now it is just plane text. Maybe adding some style to title, colors etc may be cool. I don't know how to do it, neither I have too much time. If you want to see where it is such code it is in DEVImageWorkspaces >> openWelcomeWorkspace in the package ImageForDevelopers-pharo from the repository http://www.squeaksource.com/ImageForDevelopers Thanks in case someone can help.

Re: [Pharo-users] [ANN] Traits installer/uninstaller utility

by Tudor Girba

Hi Johan, I took a quick look and it looks interesting. Just a note for discussion. Executing "AspectMapsUI open" installs the traits. One of your trait extension is adding TAMStructuralZoom to FAMIXClass. Now, when I browse the FAMIXClass, I get this in the browser: ----- FAMIXType subclass: #FAMIXClass uses: TAMStructuralZoom instanceVariableNames: 'isInterface' classVariableNames: '' poolDictionaries: '' category: 'Famix-Core' ----- There are two problems with this: 1. So, now if I just want to edit the base class, I have to take care and delete the Trait before, because the Trait is part of the definition. This is a limitation of the browser, but we have to pay attention to it. 2. If you look in Monticello, the base package (FAMIX-Core in this case) is not dirty, but if you explicitly look for Changes, it gets dirty. I do not know how this could be solved. Perhaps we need extension as first class?

I get the expected result now. I'll have to inspect the rest of my (ab)use of Aliens now, but that shouldn't take long. After that I'll have to find out where I should explicitly free Aliens and where the garbage collector will do that for me. I am sure I have built in some nice memory leaks. :-) Thanks again!

Newbie: Does Socket ping: 'addr' work in Pharo3.11.8 ?

by RickT

I installed the one-click version on Windows (XP) recently and am learning Smalltalk. I am under the impression that in a Shout Workspace I can execute the line Socket ping: 'localhost' (or some valid address). But I always get a message that it timed out. I can successfully ping the same address in a command window. Any guidance would be appreciated. -- 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.
