[Pharo5] Status: 23 open issues
by marcus.denker＠inria.fr April 20, 2016

April 20, 2016

Hi, There are now 23 open issues tagged for Milestone âPharo5â. https://pharo.fogbugz.com/f/filters/125/5-0-All The plan is to release in 2 weeks. Please check if - all these issues are real show-stoppers. The idea is that e.g. everything that was already a problem in Pharo4 can not be a showstopper, as we did release Pharo4â¦ - Did you report an issue that is not listed here? New issues are do now pre-fill the form with âPharo6â, but then, if an issue was reported e.g. last week and nobody realised it was in the wrong milestone, I guess it can be said that this issue by default is not a show-stopperâ¦ - If you have this âobviousâ bug that is so obvious that you did not even report it: Keep in mind that it will *not* be fixed as we do not know about it. It does not exist. Marcus

Hi, I'm trying to unzip a file I did this : GZipReadStream unzip:'aPath/myZip.zip' to: 'aPath/test' asFileReference It's not working and I don't really understand the doc of the method, why does unzip want as first argument the name of the file only? Valentin

Any hope for Smalltalk on Raspberry Pi?
by ReliableRobots.com April 17, 2016

April 17, 2016

I have Squeak on a RPi but I don't know how to access any USB peripherals or how to make primitives to do so. I want to use RPi for controlling a microcontroller and processing webcam video for my robot. If I can't get that in Smalltalk can it be added or what language should I move to? I was referred to http://car.mines-douai.fr/category/software/pharos/ but I can't get it to work on RPi. A major focus of RPi is to teach electronics but without access to the peripherals, Smallltalk is not useful. But some access is available in Scratch which is built on top of Squeak so why can't I get access to that code directly instead of going through the Scratch changes file? Why can't I get Smalltalk goodies like I used to buy from Digitalk? With all the VM work, there must be a way to hook up C++ code like OpenCV to do real time video contours and other image recognition algorithms. Dolphin has a somewhat easy way to add primitives. If Squeak all in one contains package bundles only for Mac, why not include essentials for RPi?

Hello, I tried this: ./pharo Pharo.image eval "Metacello new baseline: #YourTribes; repository: 'github://HappyPharoHackers/YourTribes; load: #(tests)' It seems to load everything but unfortunately when I open the image, I don't see my packages And when I evaluate the Metacello expression in the playground then it works. What is the problem ? Cheers, Thomas

RBAddClassRefactoring ensuring existence
by Peter UhnÃ¡k April 17, 2016

April 17, 2016

Hi, is it possible to "ensure" that class exists with RBAddClassRefactoring? Right now RBAddClassRefactoring will throw up if the class already exists. I would like it to create the class if it doesn't exist and just do nothing if it already exists. Is it possible? (if not I will just work around it on my side). Thanks, Peter

GTDebugger shortcuts usability
by Peter UhnÃ¡k April 17, 2016

April 17, 2016

Hi, I'm getting fed-up with GTDebugger shortcuts since they are completely random. Can we have them more meaningful and/or somehow visible? For now I ended up overriding the labels so I can at least see them... but doing this is also stupid, because I still have to look at them since I cannot remember random shortcuts. â 1. can we unify the shift vs ctrl+shift nonsense? (I'm using linux btw) 2. can we use the default shortcuts pattern where one of the letters is underlined? Peter
