Re: [Pharo-dev] Catalog does not update to include MessageFlowBrowser

by Torsten Bergmann

Hi Esteban, Unfortunately it is now completely broken, the JSON is not returned anymore: http://catalog.pharo.org/catalog/json gives MessageNotUnderstood: receiver of "repositoryUrl" is nil Can you have a look again?

Re: [Pharo-dev] [squeak-dev] Criteria For Plugin Compatibility

The issue is the header size of an object. Some plugins, but not all, use this define, and the header sizes between Spur and V3 are incompatible. b) 32-bit plugins won't work with 64-bit VMs, and 64-bit plugins won't work with 32-bit VMs. Period. Now there are platform-level packaging technologies, such as fat binaries on Mac OS X, that allow one to construct plugins that contain more than one binary. But this is a lot of work to build and maintain. So personally I wouldn't put much effort into this level of drag-and-drop compatibility. Instead I'd put energy into good error messages so that when plugins don't work the user can find out why, and that when the wrong kind of plugin is used the VM doesn't just stumble along, maybe producing incorrect results, but instead puts the plugin out with a comprehensible complaint. Does this make sense? I know its a downer, but what you propose is, IMO, not affordable given our resources. And I must say, *this is a VM-DEV discussion, not a general purpose Squeak discussion*, yes?

(Point slotNamed: #x) propertyAt: #note One could build a user interface around that. Properties are not saved with monticello, though. They are like method properties. So one would need to build something on top... Another idea would be to make a subclass of InstanceVariableSlot that stores the note in a property but it is actually part of the slot definition: Object subclass: #Point slots: { #x => InstanceVariableWithNote note: âthis is uselessâ. #y } classVariables: { } category: 'Kernel-BasicObjects' As the note is part of the slot definition, it would be saved in Monticello. (unrelated: I still am tempted to just use the term âinstance variableâ and get rid of the term Slot.. for the paper is was nice, but now? Especially as we have slot like first class ClassVars and Globals that nevertheless are not slotsâ¦) Marcus

Annotating instance variables

by HernÃ¡n Morales Durand

I saw some interesting reflection progress in Pharo 5. I wonder if there is a feature to rank instance variables. For example, from the browser I want to assign a category "important" to an instance variable, or "possibly useless", etc. for later refactorings. Is such thing "easily" possible now? There is API support from Reflectivity maybe? Cheers HernÃ¡n
