Working directory and image directory
by Davide Varvello July 30, 2020

July 30, 2020

Hi Guys, As I already described here: http://forum.world.st/Fuel-FLSerializer-tests-are-not-working-pharo-8-td512… there is something weird on Pharo 8 (on Mac) because I'm running an image that is in the same directory of the Pharo.app but "FileLocator workingDirectory" give me the root directory. I expected the same directory where there is Pharo.app Cheers Davide -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Class side vs instance side (variables and methods)

When we say "class side" and "instance side", we are using a shorthand for the two objects involved. In most Smalltalks, the "class side" is really a meta-class and the "instance side" is really the class. The browser is designed to present them together because it makes sense to do that. Both sets of behaviours and variables are inherited by subclasses. [I'm playing a little loose here, as there is a distinction between a Class Variable and a Class Instance Variable in the meta-class.] The meta-class/"class side" typically deals with instance creation and management. The "instance side" provides the behaviours associated with the instances of the class. > TIA for reading my silly questions. > Not silly at all. This is a somewhat opaque topic since the browser makes it appear less obvious.

Class side vs instance side (variables and methods)
by G B July 28, 2020

July 28, 2020

Being new not only to Smalltalk, but OOP in general, I think I finally am understanding things. One area I am still unsure about is the class side versus the instance side. Does one usually use the class side when they want those inherited in every subclass, which frees one from having to declare them in every instance? TIA for reading my silly questions.

Re: Fuel - FLSerializer tests are not working (pharo 8)
by Davide Varvello July 28, 2020

July 28, 2020

Hi, I discovered why tests are failing. The reason is that Fuel is using root directory as working path instead of the working directory. Unfortunately the root dir is not writeable (of course) and so the failings. I guess the mistake occurs because since Pharo (7?) the File* and Stream* classes changed.

UFFI asynchronous callbacks
by ASAM July 27, 2020

July 27, 2020

I use Pharo 8(64bit) UFFI to call a dll(64bit). Over the dll I have access to 1 or more hardware devices. The dll has a function where I can register a call-back function. The callback is invoked whenever a hardware is connected or disconnected from PC. At the moment, Pharo always crashes when the callback is executed by the dll. Before I waste my time trying to find the bug. I wanted to ask firstâ¦ Is Pharo supporting asynchronous callbacks? I also found this old thread but the last entry is from 2017. http://forum.world.st/UFFI-with-asynchronous-callbacks-td4993968.html#a5014… Now I wanted to check the current status. Thanks for your help. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
