basicNew usage pattern
by Ben Coman May 30, 2017

May 30, 2017

A question arose in Discord regarding #basicNew, to which I felt like the proper answer should be that #basicNew is used only** from the class-side when making custom initializers. (**excepting special meta-handling like by Behaviour) This philosophy is somewhat supported by... (#basicNew senders select: [:sender | sender methodClass isMeta]) count ==> 264 but there are also counter examples... (#basicNew senders select: [:sender | sender methodClass isMeta] not) count ==> 76. like these... Example1 -- DAPackageRelationGraph>>addMessageSendDependencies: aPackage analyser := DAMessageSendAnalyzer basicNew initializeWith: aPackage; yourself. Example 2 -- FreeTypeFontProvider>>#updateFromFile: aFile face := FreeTypeFace basicNew fileContentsExternalMemory: externalMem . Example 3 -- HandMorph>>#moveToEvent: anEvent self handleEvent: (MouseMoveEvent basicNew setType: #mouseMove startPoint: self position endPoint: anEvent position trail: (Array with: self position with: anEvent position) buttons: anEvent buttons hand: self stamp: anEvent timeStamp) Should we be pushing these sort of basicNew + instance-side-method-call to the class side? Or do I have the wrong end of the stick? cheers -ben

crash on laptop wake up with external screen
by Christophe Demarey May 30, 2017

May 30, 2017

Hi, I just want to share that I experience regular crashes but I did not managed to determine exact circumstances. Here is the case: I run a Pharo image on my laptop with a screen connected to the laptop, leave to home (work with the laptop screen), then going back to work (with external screen plugged before logging back, still the same session) => pharo / vm crash. I attached the crash dump. Hope this helps, Christophe

I am using a fork of the official thing and also build on appveyor, so, the stack is the same.

Chrome DevTools Protocol and Pharo
by Torsten Bergmann May 28, 2017

May 28, 2017

Hi, I played around with remote controlling Google Chrome from Pharo using Chrome DevTools Protocol [1] (based on WebSockets). The video shows an example using latest Pharo 6 on Mac: https://www.youtube.com/watch?v=9F5FrQTEJWY Initial Code is on GitHub [2] if someone is interested, requires OSOSX and Zinc Websockets to be loaded. Have fun T. [1] https://chromedevtools.github.io/devtools-protocol [2] https://github.com/astares/Pharo-Chrome
