But does the swing vm support glibc 2.13 _intentionally_ or on accident by just being half a year old? Because it doesn't say that anywhere so as a user I would have no idea of knowing. And since I have debian testing/unstable then I already have glibc 2.19+. And this is why I am that some explanation should be put there. Peter

Re: [Pharo-dev] Nautilus: Why is Search Field Pre-filled?

by Peter UhnÃ¡k

I think there is a problem with it... if I browse a class with shortcut "ctrl+b", then the name of the package where the class is is added to the search. This at least to me quite annoying as I often do lookups of other classes but I am not interested in the whole package... so every so often I have to clear it. Is this a bug or a feature?

Hi Sean ! I tried to download the executable of PharoLauncher for my Windows 8 system from here (https://ci.inria.fr/pharo/view/Launcher/job/Launcher-Win/) Whenever I tried opening it after the installation, the entire system hung up. This was the problem I received while using the Pharo Launcher on windows platform.

when you type a search and close the browser and reopen it you do not have to retype again and again. We should revisit this pane because we could have a plus/pin button that logs the previous search. Stef Le 11/4/15 04:54, Sean P. DeNigris a Ã©crit : > What is the rationale?

Peter, The latest vm (http://files.pharo.org/vm/pharo/linux/latest.zip) in debian wheezy gives you the already know problem /lib/i386-linux-gnu/i686/cmov/libc.so.6: *version `GLIBC_2.15' not found* (required by /home/vonbecmann/workspaces/pharo-40/target/pharo) that's why you need the vm ( https://swing.fit.cvut.cz/jenkins/view/Projects/job/pharo-vm-stable-swing/l…) that requires glibc 2.13.

Frankly I have been saying for years that things like this should not be done and that folks should be prepared for the day when a configuration is no longer a class .... not quite there yet, but I guess this is the first shot across the bow ... Sending messages to a configuration should no longer be used ... I will eventually deprecate that style of loading in favor of the "scripting api style" ... the new style of loading makes use of a registry that records the actual version of projects that were loaded. The old style relied upon a calculation of "currentVersion" and "currentVersion" besides being excruciatingly slow, was often inaccurate ... there is a whole class of bugs that are eliminated by the "scripting api" ... there are also a whole slug of new features that are available when using the "scripting api". Configurations are SUPPOSED to be platform neutral, so including magical, arbitrary Smalltalk expressions as part of the required load sequence is just right out of bounds from the get go ... I know that folks have done all kinds of "clever tricks" over the years with configurations taking advantage of the fact that they are classes and early on I did make noise whenever I saw someone doing that ... but I could only warn folks that it was not a good idea and since "boys will be boys" this practice has continued and my protests fell on deaf ears ... With all of this said, I am curious as to is so special about these class-side selectors that they cannot be accomplished through the existing "scripting api" ... there are already facilities for execution "arbitrary code" within the configuration framework that does respect the platform boundaries, so I would imagine that most of the cases can be converted ... Sooo if there are problem areas I would be interested in understanding the use cases ... Dale

You mean like loading a particular group? As Christophe mentioned, we have the Metacello scripting API now: Metacello new configuration: 'Magritte3'; smalltalkhubUser: 'Magritte' project: 'Magritte3'; version: #bleedingEdge; load: 'Morphic'. "<------------- Load specific group" Tudor Girba-2 wrote > but it is clear that it is intended for scripts and not for production > code. It's not clear to everyone given Steph's OP ;) So how do we enforce it? I'm guessing most of the users who don't know that they shouldn't use #asClass are probably not running Lint checks (or don't even know about them) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Problem-with-asClass-usage-tp4818686p4818998.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
