Fuel materialization on spur
by Norbert Hartl Dec. 17, 2015

Dec. 17, 2015

We have a test build for pharo5 that checks if we need to do stuff for future migrations. Since yesterday it fails, of course. I have a fueled out object graph stored as byte array in a method. The fuel bytes are serialized using a non-spur image. Now when the spur image reads the bytes I get an exception. Has this something to do with immediate characters? Is there a way to fix that or will it just not be possible to exchange objects between spur and non-spur using fuel? thanks, Norbert primitive #value: in Character class failed Stacktrace Character class(Object)>>primitiveFailed: Character class(Object)>>primitiveFailed Character class>>value: Character class>>materializeFrom: FLHookPrimitiveCluster>>materializeInstanceWith: FLHookPrimitiveCluster(FLIteratingCluster)>>materializeInstancesStepWith: FLMaterialization>>clusterInstancesStep [ self clusterInstancesStep ] in FLMaterialization>>instancesStep SmallInteger(Integer)>>timesRepeat: FLMaterialization>>instancesStep FLMaterialization>>run [ :aDecoder | (FLMaterialization with: aDecoder) run; yourself ] in FLMaterializer>>setDefaultMaterialization FLMaterializer>>materializeFrom: FLMaterializer class>>materializeFromByteArray: MAPExampleModels class>>readModelFromSelector: MAPExampleModels class>>readModelNamed: [ self readModelNamed: aString ] in MAPExampleModels class>>named: [ self at: key put: aBlock value ] in Dictionary>>at:ifAbsentPut: Dictionary>>at:ifAbsent: Dictionary>>at:ifAbsentPut: MAPExampleModels class>>named: MAPTest>>model MAPTest>>tcapModule MAPTest>>testInsertSubscriberDataBitStringAccess [ testMethod perform: testMethod selector ] in Given>>produceReturnValueAt: [ self at: key put: aBlock value ] in Dictionary>>at:ifAbsentPut: Dictionary>>at:ifAbsent: Dictionary>>at:ifAbsentPut: Given>>produceReturnValueAt: MAPTest(Phexample)>>performTest

MacroRecorder updates (+ another demo)
by Gustavo Santos Dec. 17, 2015

Dec. 17, 2015

Hello guys, thanks for the support so far. I've been working on your suggestions. Some of them concerned that the example in the first demo video was too "magic". :-P So I made another video showing how the developer can manually configure the tool. Take a look: https://youtu.be/3xc3j3PjIYQ ( first demo here: https://youtu.be/gW3l4O-WEGs ) Also, I kindly remind you that I'm interested in usage data: - if you systematically modified code in the past, show me. - if you created a custom transformation with the tool, show me; or - if you had problems using the tool, show me too! :-) Feel free to provide any feedback. Cheers, -- Gustavo Santos http://gustavojss.github.io/

It destroys the simulator, which is the most important thing we have for VM development productivity. As far as I'm concerned any use of external libraries to implement core functionality kills the VM-in-Smalltalk concept that Squeak (and Pharo) are built upon. So for me it's a non-starter. I hope others agree. _,,,^..^,,,_ best, Eliot

I was just looking to show a friend at work programming for kids on the Raspberry Pi, away from my usual Smalltalk activities at home, and was surprised to find an article mentioning Scratch with GPIO and our very own Tim & Eliot, which I thought I'd share https://www.raspberrypi.org/blog/a-new-version-of-scratch-for-raspberry-pi-… cheers -ben

AsmJit

Dec. 16, 2015

Hi guys,Â two queations:Â (i) Is AsmJit going to be developed any more or it's abandoned Â Â as well as native boost? (ii)Where can I find latest AsmJit? I'm properly confused: Â Â * Is is the one in latest Pharo 4.0 (5.0) image? Â Â * Is it the one here:Â http://smalltalkhub.com/#!/~Pharo/AsmJitÂ ? Â Â Â (the one in the image seem to be based on completely disjunct Â Â Â Â set of .mcz than those in the repo above). Best, Jan
