Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2014-11-30 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

How do I get a >512MB image with Pharo 3 on a mac?
by Paul DeBruicker Nov. 16, 2014

Nov. 16, 2014

Hi - I don't have a need for a big image. I just discovered I have no idea how to make one larger than ~512MB, and am curious. I was running into an out of memory error and discussing it in a thread on pharo-users list (http://forum.world.st/running-out-of-memory-while-processing-a-220MB-csv-fi…) The details of that discussion aren't pertinent to this question. This script below ought to make an image that maxes out well above a GB but cannot cross 512MB without throwing an OutOfMemory error. | them | them := OrderedCollection new. [[them addLast: (ByteArray new: 16000000). Transcript cr; show: ((Smalltalk vm parameterAt: 3) / (1024*1024.0) printShowingDecimalPlaces: 1); flush] repeat] on: OutOfMemory do: [:ex| 2 to: them size by: 2 do: [:i| them at: i put: nil. Smalltalk garbageCollect]]. Transcript cr; show: ((Smalltalk vm parameterAt: 3) / (1024*1024.0) printShowingDecimalPlaces: 1); flush. them := nil. Smalltalk garbageCollect. Transcript cr; show: ((Smalltalk vm parameterAt: 3) / (1024*1024.0) printShowingDecimalPlaces: 1); flush In the transcript you will see an output of the image size as more ByteArrays are added to the OrderedCollection. On my laptop with 4GB of ram it always peaks at just over 500MB. Setting the memory from the command line (e.g. pharo-ui --memory 1000m Pharo.image) does not help. Is there a VM flag that I need to flip? Thanks Paul

[NB] Undocumented NativeBoost options
by Max Leske Nov. 16, 2014

Nov. 16, 2014

I got a bit frustrated and ended up searching the source for â[\w]opt[[:upper]]â to find all NativeBoost options. Some of those options are in fact undocumented: optMayGC optProxyLabels optCdecl optReturnNullAsNil optStdcall optNonMovable optReserveCallgateSpace optDebug optNoAlignment optEmitCall optNoCleanup optCheckFailOnEveryArgument optStringOrNull WinUnicode NBFFICallout>>defaultOptions documents most options but refers to NBFFICallout>>allOptions, wich does not exist. Most of the above options can be considered internal, I guess, but the one option I needed (âoptStringOrNullâ) isnât documented anywhere. I had to step through the execution to find out why my function call wasnât working (because I was trying to use âoptCoerceNilToNullâ and didnât know that strings need a special option). Iâd be very thankful if these options would be included in the documentation. Note: âWinUnicodeâ is used by the Windows code in a couple of places, even though the option name is not valid, according to NBNativeCodeGen>>parseOptions: Cheers, Max

How to add a morph to a Spec GUI
by kilon alios Nov. 16, 2014

Nov. 16, 2014

Hello guys I am trying to add a morph to spec gui before a spec button and the experience has been a nightmare so far. https://github.com/kilon/Nireas/blob/master/Nireas.package/Nireas.class/cla… I understand how columns and rows work but I cant figure out how Spec works with Morphs. I took a look at CheckBoxExample but it completely jammed my brain how complex it looks. First of all defaultSpec2 is what ? and whats the diffirence with defaultSpec ? Dont know about you but I don't like neither name defaultSpec and defaultSpec2 , I would have chosen a name like layout or something that makes sense. also why we need to initializeWidgets when we already define their order in defaultSpec ? Why cant Spec initialise those widgets by itself ? Is it really necessary for each element of the gui to be defined as a getter method ? Why not just put everything to a dictionary and make a getter for that dictionary ? It would make a complex Spec gui a nightmare to browser and leads to braking it up to more classes which will still make it a mess to browse. I see also a container defined in there , I assume it has something to do with the morphs. I took also a look at documentation at Pharo for the Enterprise and it has a section for building widgets but it looks too much work to add just a few morph to a Spec gui. I wanted to make the gui for Nireas with Spec and I like some of its design but overall it has been way more struggle than working with Morphic. I know I have complained about Spec before and sorry if I sound like a broken tape but making guis in heavily gui based environment like Pharo should not be so hard. I dont have a problem failing back to Morphic but since I see so many people praise Spec I keep wondering if I approach this the wrong way and things are much more elegant and easy than they look.

New Cog VMs available
by Eliot Miranda Nov. 16, 2014

Nov. 16, 2014

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3133/. CogVM binaries as per VMMaker.oscog-eem.934/r3133 These VMs should be functionally identical to the 3126 VMs; the core VM differs only in having been compiled from generated source that has been refactored to enable convenient 32-bit to 64-bit Spur image bootstrap. I'm building and releasing them mostly to test that refactoring. However, there is new DNS support on Windows and SSL support on Unix. See below. Simulator/Slang: Refactor to allow 32-bit and 64-bit Spur to coexist in the simulator, thereby allowing a 64-bit bootstrap. Replace direct use of BytesPerWord, ShiftForWord, BytesPerOop and BaseHeaderSize with sends of wordSize, shiftForWord, bytesPerOop & baseHeaderSize respectively. Make sure these are still output as the manifest constants in the generated C. Eliminate use of bytesPerSlot in favour of bytesPerOop. The use of sends is similar to those in trunk VMMaker, but I don't have time to merge. Sorry :-(. Work-around use of sends for bytesPerOop in e.g. generateToByDo:on:indent: and users of isConstantNode:valueInto:. Do a better job at inlining via inlineCodeOrNilForStatement:in:. Comment in isNode:substitutableFor:inMethod:in: explains. Eliminate generic VM_LABEL support, labelling only the bytecodes in interpret. Eliminate use of LargeContextSize in the stack and cog VMs. Alas haven't yet eliminated the frame offset constants such as FoxCallerSavedIP et al. We only need one of the two word sizes of interpreter to be executable in the bootstrap. And remember to generate the GdbARMPlugin Add accessorDepths for the exported browser plugin primitives for Spur. Merge Levente's recent changes to DNS lookup on Windows and SSL on Unix. See http://squeakvm.org/cgi-bin/viewvc.cgi/squeak?view=revision&revision=2249 http://bugs.squeak.org/view.php?id=7824 Have the Unix & Mac VMs print the process id and working directory when blocking on error or assert fail. Add scripts for the ARM VM archives. -- best, Eliot

Configurations and Github for a specialised configuration browswe
by kilon alios Nov. 15, 2014

Nov. 15, 2014

So I am so happy with how Pharo works with Github, that I decided to even port my configurations there and I also decided to create a small configuration browser which will subclass the existing configuration browser for installing tools for my project Ephestos so I dont have to pollute the existing configuration projects with all my sub-projects. In sort I want to host configurations to Github similarly to how MetaRepos are host in Smalltalkhub. I want the user to be able to install those configurations without a need to install git I asked this I think before and I was told how to, but it was part of another thread and it got lost inside my email abyss. So How I do that ?

[Bloc] Getting involved
by Santiago Bragagnolo Nov. 15, 2014

Nov. 15, 2014

Hi Guys, (Alan and Steph punctually) I want to comment I am getting involved with Bloc, since i need to draw several things and i need an Athens canvas. I am checking if it is the best tool for my needs. In any case I am doing some contributions that i would like to commit and to share. Actually i am working on draft a window, a tool bar, a button based on images and animations. Then, there is any mailing list for Bloc? How is the push-request cycle? Thanks :). Santiago.

How to refresh the pharo window manually
by kilon alios Nov. 15, 2014

Nov. 15, 2014

Hello guys I am making a theme manager and I have observed that when I choose a background color for pharo windows it does not update properly. How I can force the whole pharo window to update ? I have found DisplayScreen and WorldMorph but no idea how to use them.
