Hi Camillo, Do you use some code to generate the bash scripts for downloading the image and the vm? If yes it is it available somewhere? Cheers, Andrei

[Pharo-project] Cycling Through Open Windows Using Key Combination
by Sven Van Caekenberghe April 5, 2013

April 5, 2013

Hi, Is there a key combination to cycle through open windows ? I am using Apple-Tab a lot to cycle between open applications on my Mac, and Apple-~ to cycle between open windows in one application. I would love to be able to do something similar inside Pharo. 9 changes out of 10 somebody already did this, maybe it is even in the image. Thx, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Re: [Pharo-project] Issue 10219: Completion: enter on accept awkwardness

We seem to have a regression. In early may 2011 this was resolved. Tudor Girba wrote >This is not great at all.

[Pharo-project] can no longer compile code without .changes file in Pharo-2.0
by Yanni Chiu April 5, 2013

April 5, 2013

I deploy without a .changes file, but the image still compiles code at runtime. The methods are just accessor methods, and no image save is ever done. Using Pharo-2.0 (instead of Pharo-1.4), I now get a walkback: VM: unix - i686 - linux-gnu - NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 NBCogit NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 git://gitorious.org/cogvm/blessed.git Commit: 412abef33cbed05cf1d75329e451d71c0c6aa5a7 Date: 2013-03-13 17:48:50 +0100 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14535 Image: Pharo2.0 [Latest update: #20593] CompiledMethod(Object)>>doesNotUnderstand: #copyWithTempsFromMethodNode: CompiledMethod>>putSource:fromParseNode:inFile:withPreamble: ... It seems that #putSource:fromParseNode:inFile:withPreamble: calls #copyWithTempsFromMethodNode:, when there is no .changes file, but that method is not in the image. Is it safe to just patch the code to do nothing? The method comment says that the method temp names are saved for decompilation.

[Pharo-project] new Cog VMs available
by Eliot Miranda April 4, 2013

April 4, 2013

at http://www.mirandabanda.org/files/Cog/VM/VM.r2714/ These fix quite a serious bug with the JIT that would cause crashes in large images. CogVM binaries as per VMMaker.oscog-eem.282/r2714 Change application name from Croquet to Squeak and change to green Cog Squeak icons. Add accurate version info to the Windows exes (include SCCSID in properties). Add the SSLPlugin on mac and linux (won't link on old mingw; need to update). Cogit: Fix *HORRIBLE* yet ancient bug with the CogObjectRep. Both CogObjectRepresentationForSqueakV3>>couldBeObject: & CogObjectRepresentationForSqueakV3>>shouldAnnotateObjectReference: used signed comparisons for oops and so once the heap size pushes oops into the upper half of the address space constant oops in machine code were no longer being updated by the GC. StackInterpreter: rewrite the login for printing methods so that printing the frame of a bad receiver won't seg fault. Add primitivePathToUsing which mimics the PointerFinder and can hence be used to debug or verify it. Remove unnecessary forceInterruptCheck in NewObjectMemory>>become:with:twoWay:copyHash:. (heartbeat does this for us). Fix bug in assert in NewCoObjectMemory>>restoreHeaderOf:to:. Slang: Fix translation of to:by:do: loops so that the limit is not re-evaluated on each iteration if it may have side-effects. Include the correct AioPlugin (UnixAioPlugin) Include SqueakSSLPlugin in the configurations. Cogit: Stop reporting EncounteredUnknownBytecode with an error message. Fix slip in ceSICMiss: that didn't link new PIC if an MNU case. Add pixel peeker prims to BitBltPlugin. Minor signature changes to BitBltPlugin & HostWindowPlugin from SmartSyntaxPluginGenerator bug fix. -- best, Eliot

[Pharo-project] Nautilus accessor over-generation
by Sean P. DeNigris April 4, 2013

April 4, 2013

There is: Nautilus class context menu 1. - Analyze -> Create inst var accessors (which allows you to multiple inst vars, but not omit setters/getters) - Refactoring 2. -> Class refactoring -> Generate accessors (which generates all by default, but allows you to omit whichever methods you want) 3. -> Inst Var Refactoring -> Accessors (which operates on a single inst var, and allows you to omit getter or setter) #1 seems to add nothing to the party. It's the least flexible and is covered by #2. My confusion: I was always using #3 and didn't even realize #1 and #2 existed. I started to write code to select multiple inst vars at once in #3 and stumbled upon #1 and #2. Maybe #2 could be duplicated next to #3 with a more-differentiated name. Slightly OT, it seems that listing the inst var "refactorings" (is adding an inst var really a refactoring?) is kind of a hack. For me, it'd make more sense and be more OO if the browser knew how to deal with inst vars explicitly, maybe as a sidebar to the class definition, or maybe the class definition should be abstracted behind a real UI. i.e. inst var widgets instead of a string... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Nautilus-accessor-over-generation-tp4679480.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] SystemNavigation API: browseAllXyz vs. browseAbc
by Sean P. DeNigris April 4, 2013

April 4, 2013

Some selectors are of the form browseAllXyz (e.g. browseAllSendersOf:), while others are like browseAbc (e.g. browseSendersOf:name:autoSelect:) The "All"s seem extraneous. If the thing being browsed is plural (e.g. Senders instead of sender), that implies "All" since there are no other qualifiers, and there's no alternate case unlike subclasses v.s. allSubclasses. ----- Cheers, Sean -- View this message in context: http://forum.world.st/SystemNavigation-API-browseAllXyz-vs-browseAbc-tp4679… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Hi guys I'm doing a pass on the collaborative book and in particular in the tools part. I think that we should really use this place to describe the cool library we have. Probably in the future we should generate gutenberg information from the package metadata of the published package so like that we would have an up to date description of our stack. Stef

It is just pushing the limits one small piece at a time... The case where I find I would like this most, is when I notice a test method has the wrong name. It is actually not doing what it says it does. Stephan
