New, faster RISC OS Squeak
by Chris Cunnington 01 Oct '16

01 Oct '16

I get a File 'System:Modules.StreamMan' not found error. I take it from here [1] [2] that StreamMan is short for StreamManager. And that it should be in the sharedsoundbuffer.!System folder. I shift+double clicked and followed !Shared.350.Modules to see StreamMan in this directory. The file appears present but still there is an error.

Running headless on a Mac
by Frank Shearar 03 Jul '16

03 Jul '16

OK, so I've run out of patience in my flailing around. All I want is to run a headless image on a Mac (so I can unbreak the SqueakTrunk-OSX job, which _used_ to work). How? Do I say "-headless"? ("could not find module vm-display-X11") "-vm-display-null -headless"? ("squeak: could not find any sound driver") "-vm-sound-null -vm-display-null -headless"? ("could not find module vm-sound-null") I don't mind whether I use Cog or Interpreter, as long as I can just get an image running tests. Thanks! frank

trunk update broken cuz there's an empty diffy version
by Eliot Miranda 24 Apr '16

24 Apr '16

Hi Guys, source.squeak.org/trunk's Morphic-eem.740(cmm.739).mcd is empty. How do we fix it? On a related note is there any way to get the updater to download full packages, avoiding the diffy versions? e.g a preference? -- best, Eliot

deselection broken in method list
by Eliot Miranda 17 Apr '16

17 Apr '16

Hi All, I depend heavily on fileOutAll in method list browsers. For example, I'm trying to create versions of the VM's boolean cheat code for the Sista bytecode set and do this by filing out the code for the Newspeak set and editing it. I tried to do this using "self systemNavigation browseAllSelect: [:m| ('*ooleanCheat*V*' match: m selector) or: [m sendsSelector: #booleanCheatV4:]]" to get a method list browser. Then I was expecting to be able to use file out with nothing in the list selected. This files out all methods in the list but... Deselection is broken! I can't deselect the first item and hence can only file out a single definition . Will whoever changed this please restore it asap? (in trunk) -- Mahalo, Eliot

Breaking up ToolBuilder
by Frank Shearar 17 Feb '16

17 Feb '16

I noticed this morning that every package that uses ToolBuilder has a transitive dependency on both Morphic and MVC (in the form of the ST80 package). This is caused by MorphicToolBuilder and MVCToolBuilder. I suggest either rename 'ToolBuilder-Morphic' to 'Morphic-ToolBuilder' and 'ToolBuilder-MVC' to 'ST80-ToolBuilder' (or'MVC-ToolBuilder'). This would move Morphic-specific stuff where it belongs, and ditto for MVC. frank

It's not yet clear how serialization should work in the presence of environments
by David T. Lewis 30 Nov '15

30 Nov '15

Currently we have: Binding>>objectForDataStream: refStream "It's not yet clear how serialization should work in the presence of environments" self shouldBeImplemented. This prevents us from being able to save projects to local disk in Squeak trunk. See Mantis entry at: http://bugs.squeak.org/view.php?id=7814 Any thoughts as to how this should be implemented? Taking the method comment literally, I would expect that serialization in the presence of environments should work identically to serialization in the absence of environments, at least as a default behavior. I suspect that is not hard to make this happen, but I don't know how to do it. Dave

Environments update
by Colin Putney 25 Nov '15

25 Nov '15

Hi all, So I've been plugging away at Environments, and have a new implementation that supports renaming, but I wanted to get some feedback before figuring out the sequence of commits necessary to update the trunk safely. The idea is to support this kind of scenario: seaside := (Environment named: #Seaside) import: Smalltalk globals; importSelf; exportSelf; yourself. magma := (Environment named: #Magma) import: Smalltalk globals; importSelf; exportSelf; yourself. app := (Environment named: #AwesomeApp) import: Smalltalk globals; import: seaside; from: seaside import: {#Session -> #SeasideSession}; import: magma; from: magma import: {#Session -> #MagmaSession}; importSelf; exportSelf; yourself. In order to have the decompiled code use the correct names, I've changed the way lookup works. Instead of moving bindings from one environment to another, we now create a separate set of bindings for each environment, and copy the values (i.e., classes and globals) into a new binding when a binding is imported. I had originally thought to use something like #changed:/#update: to keep all the bindings in sync, but then I realized that ClassBuilder does a #becomeForward: updates a class. So it's really only globals that could become out of sync between environments. Since we have very few globals in the image, and they basically never change, an update mechanism may not be necessary in practice. So, here are some possible ways to proceed: 1. Use #changed:/#update: or something similar to keep keep global variables in sync. 2. Idea from Eliot—adopt the same convention as VW, and send #value to the binding on every access. Then we could have a special Alias bindings that forward the #value message to the original binding. 3. Share bindings for global variables between environments and disallow renaming of globals. 4. Special case the traditional globals such as Transcript and Display, and disallow the creation of new globals. Anyhow, I'd appreciate a code review from anybody who's interested in this stuff. To take a look, file the attached (hand edited) change set into an updated trunk image. Thanks, Colin

Maintainer of FFI-Package
by Nicolai Hess 12 Sep '15

12 Sep '15

Who is the maintainer of the FFI-Package for Squeak and/or Pharo ? I especially interested in the FFI-Unix examples and the state on working FFI on linux for current squeak release (AFAIK it does not work with "squeak all in one" 4.5) regards Nicolai

The above change restores the old behavior of locking up the image, so it should be reverted. An additional comment explaininng why aBlock must not be evaluated inside the argument of #accessDictionaryOfPreferencesIn: would be helpful. It would be even better to finally get rid of DictionaryOfPreferences. Levente

Looking for a volunteer to help with DataStream on Spur
by Eliot Miranda 26 Jun '15

26 Jun '15

Hi All, Spur adds two new immediate classes, Character and SmallFloat64. It also adds 61-bit SmallIntegers in 64-bits. DataStream/ReferenceStream/SmartRefStream are all affected by this. e.g. ReferenceStream testWith: $a fails on 32-bit and 64-bit Spur. ReferenceStream testWith: SmallInteger maxVal fails (silently, to be fixed soon) on 64-bit Spur. Is anyone kind enough and motivated enough to give this code some love and at least make it work for 32-bit Spur => 32-bit Spur 64-bit Spur => 64-bit Spur but also hopefully for 32-bit Spur <=> 64-bit Spur 32-bit V3 => 32-bit Spur 32-bit V3 => 64-bit Spur ?
