Abbreviations
by Torsten Bergmann July 4, 2013

July 4, 2013

Usually I thought only the C/C++ people fell in love with abbreviations - but now its our own community: in Pharo 3.0 one can write: Smalltalk os env or would it be better to use: Smalltalk operatingSystem environment in the future? So is the current Smalltalk vm better than Smalltalk virtualMachine I know: even a newcomer should know what "OS" means. At least Smalltalkers/Java people should know they need a "VM". But nonetheless I think a common goal would be to keep Pharo code and method selectors readable and avoid abbreviations when possible. Also there are Pharo methods like #getEnv: instead of #getEnvironmentVariable: (interesting that they wrap the native C/C++ API "GetEnvironmentVariableA" which does not use abbreviations) Should we care (with an issue) and use the more readable forms in the future and deprecated the abbreviation forms? Or will we keep abbreviations for the lazy and easier typing? If you comment please think about the goal to get readable code, the goal to get more newcomers into programming and your own first steps with Smalltalk and IT ...

[Warning] SmalltalkHub, Pharo association and Pharo consortium websites down
by Nicolas Petton July 4, 2013

July 4, 2013

Hi! All our services (including backup servers) are currently down due to power issues with ERDF at our datacenter (you can follow it on twitter) https://twitter.com/online_fr/ They were running on a generator power for some time, but it seem to have finally failed too. All their support lines are busy, and we can't reach them by email either. I'm doing my best to resolve the issue as soon as possible, they promised us that the power would be back in 20'. I'm really sorry for the inconvenience. Cheers, Nico

[Pharo-project] Understanding NBOpenGL
by kilon July 4, 2013

July 4, 2013

Ok so I tried to learn Opengl ES 2 (and opengl 4) during my eastern vacations because I realised that I dont really need Athens or vector graphics for my GUI , since I will be dealing mostly with 3d graphics anyway. (My project "ephestos" will be an effort of creating a 3d app for pharo, see also "blender") So when I tried to run the demos i get an error with NBMacGLContextDriver>>supportsCurrentPlatform "obviously, for Mac intel-32 only :)" ^ NativeBoost platformId = NativeBoostConstants mac32PlaformId My mac is "obviously" not 32-bit but 64 bit, but I dont know if that matters since pharo is only 32 bit anyway. The bug is also obvious it should be mac32PlatformId and not mac32PlaformId. I correct and proceed and gives me a new error this time in NBMacGlApi>>glApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry ^[ (NBCallFailureHandler for: contextToRetry) retryWith: [ :targetClass :targetMethod | (NBFFICallout targetClass: targetClass targetMethod: targetMethod fnSpec: fnSpec) stdcall; generate: [ :gen | self emitCall: fnIndex generator: gen ] ] ] on: NBNativeCodeError do: [:err :handler | err errorCode = ErrorFnNotAvailable ifTrue: [ "Native code is installed, but function pointer not loaded yet. Try to load function and retry the call" (self tryGetFunctionPointer: (self class glFunctions at: fnIndex)) ifFalse: [ ^ err pass ]. ^ handler retrySend ]. err pass ] The problem here that NBCallFailureHandler is nowhere to be found. At first I though my NB was lagging behind in version so I download from smalltalk Hub and did ConfigurationOfNativeboost loadStable. it updated without errors but still that class is nowhere to be found. So my question is this, does it really worth it to struggle with NBOpengl or will it better to learn how Nativeboost works and use Opengl myself ? -- View this message in context: http://forum.world.st/Understanding-NBOpenGL-tp4686514.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Possible PharoVM bug (wrong object on stack top)
by Max Leske July 4, 2013

July 4, 2013

Hi I've been seeing a particular bug that I can only see when using the PharoVM and I was wondering if anybody else has been having the same issue. Under certain condition, a debugger will open displaying "SmallInteger does not understand <some message>". The stack top contains an integer (something of the form 138402, not sure how many digits), which explains the message. However, the situation actually looks like this: htmil anchor id: 'foo'; â¦ In this example, the error would be "SmallInteger does not understand #id:". So the stack top contains an integer instead of the receiver. Restarting the execution of the method and proceeding fixes the problem. I think I've seen that (using seaside), a new session will trigger the bug again. Apart from Seaside, I've also seen the same problem when loading Roberto Minelli's DevFlow into a Pharo 2.0 image. The debugger will open on a Metacello method. VM: latest PharoVM image: latest 2.0 try this config: http://smalltalkhub.com/#!/~RobertoMinelli/DevFlow with "ConfigurationOfDevFlow loadDevelopment" Has anybody else encountered this? Cheers, Max
