[Pharo-project] Zinc: Detect failed binds
by Mark Smith June 13, 2012

June 13, 2012

Hi :), Does anyone know if there's a way to detect if a Zinc Server doesn't bind to a port, (probably because there's already a server listening on that port), and signal an error? Thanks a lot, Mark

[Pharo-project] recompiling class
by S Krish June 13, 2012

June 13, 2012

Can we do this in Pharo: "in Java, the computation of numeric o ffsets for instance elds in memory is done by the run-time system. This permits updating a class with new instance elds or methods without aff ecting existing code. In other words, it is possible to run an existing bytecode fi le for a subclass after updating and recompiling the class, but without recompiling the subclass."

[Pharo-project] FileReference should throw error when deleting unexisting files?
by Mariano Martinez Peck June 13, 2012

June 13, 2012

So if we now do: 'afileThatDoesntExist' asFileReference delete I get a PrimitiveFailed. If this is what we want, can I add: FileReference >> deleteIfExists self exists ifTrue: [ self delete] or something like that? because lots of places (tearDown of tests) I want to remove crao which may or may not exist... thanks -- Mariano http://marianopeck.wordpress.com

And the image where it works the code is not commened. If I uncomment the code of course it works.

[Pharo-project] subclassResponsibility, how does it work?
by Gareth Cox June 12, 2012

June 12, 2012

Hi All I'm attempting to subclass a class (Point) and I want some instructions passed to Point to go to MyPoint. Specifically I have Point >>asMyPoint >> self subclassResponsibility. In MyPoint I've got asMyPoint ^x@y. When I execute code, I get an error that the subclass should have executed... How does this actually work? How should I do this? Kind Regards Dusty

PaulLePoulpe Logger is now working and tested on Pharo 1.3 core; 1.4 and 2.0, and working with two red tests at Pharo 1.2 core. The two red tests are related with an announcement issue. But it dont interfere with the work, so, it works. I'm using it actively in ConcreteTypeInference and KwisatzHaderach projects swiching configurations depending on which project im working, and work perfect. That's why i decided to make the first version. Gofer new url: 'http://ss3.gemstone.com/ss/PaulLePoulpe'; package: 'ConfigurationOfPaulLePoulpe'; load. ( (Smalltalk at: #ConfigurationOfPaulLePoulpe) project version:'1.0' ) load

[Pharo-project] 2.0
by Schwab,Wilhelm K June 11, 2012

June 11, 2012

I grabbed the one-click image and poked around. The worst thing I found (can't reproduce) is that the SB's package list became insensitive to clicks. Switching to groups and then back seemed to restore normal operation. Looks good so far! Bill
