Sept. 19, 2016

Hi, I'll like to know what is happening exactly in background when I'm using a symbol as in *Collection withAllSubclasses collect: #numberOfLinesOfCode*. I also want to know the other cases where I can use symbol. Is there any tutorial about using symbol?

Is someone working on RFID tags?
by HernÃ¡n Morales Durand Sept. 18, 2016

Sept. 18, 2016

Recently I've been working on a model for RFID for animal identification using ISO 11784. I would like to have a nice model of RFID Tag types, Readers ,etc. (alternatively, if you know an object model to share I am also interested). If there is someone working on this in Pharo we could join efforts. Cheers, HernÃ¡n

Class shown in _UnpackagedPackage but belongs to package
by Esteban A. Maringolo Sept. 18, 2016

Sept. 18, 2016

Hi, After renaming, promoting as tag, moving to package and other non-secuential operations in Nautilus which screwed up the packaging, now all classes are shown in _UnpackagedPackage but when browsed via Spotter they show the right package in the class template. SequenceableCollection subclass: #OrderedCollection instanceVariableNames: 'array firstIndex lastIndex' classVariableNames: '' package: 'Collections-Sequenceable' Any pointers on how to fix/rebuild whatever is needed? It took me two classes and less than 5 minutes to screw it, I guess it's a new record. :) Regards! ps: this happens with the latest 5.0 image and vm version. Esteban A. Maringolo
