[Pharo-project] 1.4 ready?
by Pavel Krivanek April 9, 2012

April 9, 2012

Hi, as I see on http://code.google.com/p/pharo/issues/list?can=2&q=label%3AMilestone-1.4, there are only three open issues for 1.4. Two of them are ready to integrate and one needs only CI configuration. Are we ready to release? Cheers, -- Pavel

[Pharo-project] about cmd+b, cmd-n
by StÃ©phane Ducasse April 9, 2012

April 9, 2012

Hi A while ago I added the fact that cmd+b on a selector behave as cmd+m cmd+m on a class behave as cmd+b cmd+N on a selector as cmd+n cmd+n on a class as cmd+N but we lost this cool change probably with the new text editor. Could somebody have a look because it was a cool and simple usability improvement. http://code.google.com/p/pharo/issues/detail?id=5588 Stef

[Pharo-project] Milestone reached :-)
by Pavel Krivanek April 9, 2012

April 9, 2012

Hi, I created an experimental CI build that loads Fuel into the Pharo Kernel, unloads Compiler and uses an special launcher that expects a binary package name as command line argument. https://ci.lille.inria.fr/pharo/view/Pharo-Kernel/job/Pharo%20Kernel%20Fuel/ You can test it with something like (see attachment): CogVM PharoKernel-Fuel-1.4.image testingPackage.fuel Following code exports a fuel binary package from the image: FileStream forceNewFileNamed: 'testingPackage.fuel' do: [:aStream | aStream binary. FLPackageStore new storeOn: aStream packageNamed: 'TestingPackage'.]. As you can see from the output of the testing class, there is no Compiler class in the image. Cheers, -- Pavel

[Pharo-project] SMark
by Martin Dias April 9, 2012

April 9, 2012

Hi. I like SMark, so I am evaluating how straightforward would be to move Fuel benchmark suite. A couple of questions: 1) I had some undeclared references, no problem? HeadlessSave class>>run: (RVMOperations is Undeclared) ScriptStarter class>>transportersForFileOutMenu (Transporter is Undeclared) 2) Can I run benchmarks in headless mode using ScriptStarter? How can I try HelloWorld script? I couldn't figure out. Thanks, MartÃn

[Pharo-project] Recover from an MNU in start up list?
by Philippe Marschall April 9, 2012

April 9, 2012

Hi I extracted a superclass and now I get a MNU during image startup because I have an instance of the now abstract base class in the start up list. The image comes up for a fraction of a second and the crashes (PharoDebug.log). Any idea of how I can recover from this? Cheers Philippe

[Pharo-project] tail-like
by Tudor Girba April 8, 2012

April 8, 2012

Hi, I am looking for a way to implement a logic like in the linux tail command: watch a file and react whenever a new line appears at the end of that file. Can anyone point me to some resources that I might use for something like this? Cheers, Doru -- www.tudorgirba.com "When people care, great things can happen."
