Shrinking
by Colin Putney 20 Oct '14

20 Oct '14

Hi folks, What's the state of the art in shrinking these days? I'm starting a new web project with Squeak, and I want to create a smallish base image that I can use to build up images for development and deployment. It doesn't have to be absolutely minimal, just unloading unnecessary code and cleaning up the registries, clearing caches etc would fine. I tried "Smalltalk shrinkAndCleanDesktop", but it complains about obsolete behaviours still being present, so I guess there's some bit rot there. Suggestions? Colin

OpenGL procedural textures generator (by David Faught) for Squeak 4.4
by Nikolay Suslov 09 Jun '14

09 Jun '14

Hello, I have successfully proceeded in running TweakCore on the recent Squeak 4.4 trunk image (from Jenkins). And one of the famous existed applications developed in Tweak is the OpenGL procedural textures generator by David Faught. I make it also loadable to the current Squeak. You could download the ready to run image from here: http://krestianstvo.org/TweakCoreOpenGL-squeak44.zip or execute in the workspace in own image: "1. Load FFI" (Installer repository: 'http://source.squeak.org/FFI' ) install: 'FFI-Pools'; install: 'FFI-Kernel'; install: 'FFI-Tests'.. "2. Load CroquetGL " (Installer repository: 'http://www.squeaksource.com/CroquetGL') install: '3DTransform'; install: 'OpenGL-Pools'; install: 'OpenGL-Core'. "3. Load TweakCore and Procedural textures application for Tweak" (Installer repository: 'http://sdk.krestianstvo.org/sdk/inbox') install: 'tweakcore'; install: 'Tweak-OpenGL-sn.3'. "4. Set the default settings in Tweak" CDefaultWidgetLibrary setDefaultSettings. "5. Run one of two examples" CProjectMorph open: Wrinkle1. "or" CProjectMorph open: Wrinkle2. The attached screenshot shows the running application. Regards, Nikolay

Mantis usage rules du jour
by tim Rowledge 19 Feb '14

19 Feb '14

I'm submitting a bug fix and thought I'd ask what the current favoured procedure is. Simply submitting is as irritating as it ever was in Mantis, but once I've done that, uploaded my fix and made a note about it… what do we do next? To whom might I assign it for action in getting into the image for the next release? Or is that done some other way now? Is there documentation on the current process that I failed to spot? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: XO: Execute Operator

Cog already supports multiple bytecode sets. The current compiled method header format has only space for a single bit so Cog currently supprts two bytecode sets. The Squeak VMs support only the current Squeak V3 + closures bytecode set (see EncoderForV3PlusClosures). Teh Newspeak VMs support that, extended with two bytecodes for the old Newspeak implementation, and a new bytecode set that I designed for Newspeak that supports absent receiver sends. It's very much a first cut and we may do more bytecode sets. In a Newspeak image look for EncoderForNewsqueakV4, and in the VMMaker package look for initializeBytecodeTableForNewspeakV4 > My own > design allows multiple bytecodes but it is very costly to switch between > them. > Why is it costly? In Cog it is essentially free in the JIT, and in the interpreter it is a matter of testing a flag on method activation and return and setting the bytecode set offset as a result. I'm grateful to Claus Gittinger for this technique. So in the Cog Newspeak Interpreter the bytecode dispatch case statement has 512 entries, 256 for the Squeak V3 + Closures + Newspeak set, and 256 for the NewsqueakV4 set. The dispatch looks like fetchNextBytecode "This method fetches the next instruction (bytecode). Each bytecode method is responsible for fetching the next bytecode, preferably as early as possible to allow the memory system time to process the request before the next dispatch." self cppIf: MULTIPLEBYTECODESETS ifTrue: [currentBytecode := self fetchByte + bytecodeSetSelector] ifFalse: [currentBytecode := self fetchByte] setMethod: aMethodObj "Set the method and determine the bytecode set based on the method header's sign. If MULTIPLEBYTECODESETS then a negative header selects the alternate bytecode set. Conditionalizing the code on MULTIPLEBYTECODESETS allows the header sign bit to be used for other experiments." <inline: true> method := aMethodObj. self assert: (objectMemory isOopCompiledMethod: method). self cppIf: MULTIPLEBYTECODESETS ifTrue: [bytecodeSetSelector := (self methodUsesAlternateBytecodeSet: method) ifTrue: [256] ifFalse: [0]] where setMethod: is called on return, and its close twin setMethod:methodHeader: is called on frame build. -- best, Eliot

Re: [squeak-dev] The Inbox: Compiler.quasiquote-eem.248.mcz
by Eliot Miranda 05 Feb '14

05 Feb '14

Hi All, I had fun implementing a quasi-quote for Squeak today. This is a convenient way of embedding substrings in format strings (a little like printf), and, because it uses a different quote character, a convenient way of embedding code form other languages in a string literal. An example of the former usage is `hello [#cruel] world` which evaluates to 'hello cruel world' And `Float pi is [Float pi]` evaluates to 'Float pi is 3.141592653589793' An example of the latter use is that one can write `printf("%s: %c\\n", "a string", 'C');` instead of 'printf("%s: %c\n", "a string", ''C'');' This last example shows a limitation; The use of \ to escape characters ($\ $[ and $`) in quasi-quote might not be such a good choice. Anyway I thought I'd put this in the in-box for people to play with and savage. Please let me know what you think, both about the semantics and the implementation. This is a quick hack and I'm sure that there's plenty of scope for clean-up. cheers Eliot On Tue, Feb 5, 2013 at 9:54 PM, <commits(a)source.squeak.org> wrote: > A new version of Compiler was added to project The Inbox: > http://source.squeak.org/inbox/Compiler.quasiquote-eem.248.mcz > > ==================== Summary ==================== > > Name: Compiler.quasiquote-eem.248 > Author: eem > Time: 5 February 2013, 9:54:20.317 pm > UUID: ef044906-3339-48cc-856b-9b5172e3e81b > Ancestors: Compiler-cwp.247 > > Add a quasi-quote form that allows convenient embedding > of substrings within a format string, and provides a > convenient way of embedding literal strings within an > alternative literal string whose string delimiter is different. > > e.g. > `hello [#cruel] world!` > evaluates to > 'hello cruel world'. > > `S1[B1]...SN[BN]SN+1` > > is equivalent to > { 'S1'.

Timing out Trait tests
by Frank Shearar 01 Feb '14

01 Feb '14

A bunch of the Trait tests fail, despite no one having worked on the Traits code in quite a while. The symptom is that the tests time out [1]. I've tried to debug some, only to find that they pass. For instance, <timeout: 60> sometimes "fixes" the tests. But the tests shouldn't be failing. Any takers? frank [1] http://build.squeak.org/job/SqueakTrunk/756/testReport/TraitsTests.Kernel/T…

java interpreter/compiler hosted with Spur?
by charlie robert 31 Jan '14

31 Jan '14

I was curious whether java may be used in Cog. I recall a fair project with the serialization and core pojo representation, but my memory Might java interoperate natively, so as to call a java function in smalltalk, as a smalltalk call with a closure/continuation, or perhaps in the other direction? COudl a scala type inferencer be built in Spur’s runtime? runtime? Eliot, I am quite intrigued on your blog post on Spur’s object stack representation. Does this format touch on the heap structure of an object? Either way, using Cap’n Proto in the heap and Spur for the stack/queue structures would be really nice if someone had one. Does a lord or lady own such a magic item +4? on a raspberry? so sorry for all that noise , - charlie (Rob WIthers)
