[Pharo-project] We will deprecate ProtocolBrowser
by StÃ©phane Ducasse Sept. 17, 2011

Sept. 17, 2011

Hi guys I'm sorry but ProtocolBrowser is the last user of MessageSet so we will deprecate it. We cannot continue to have old code that hamper making the system really better. Stef setClassAndSelectorIn: csBlock "Decode strings of the form <selectorName> (<className> [class])" | i classAndSelString selString sel | sel := self selection ifNil: [^ csBlock value: nil value: nil]. (sel isKindOf: RGMethodDefinition) ifTrue: [ ^ csBlock value: sel realClass value: sel selector ]. "MethodReference should be remove" ((sel isKindOf: MethodReference) or: [sel isKindOf: SourcedMethodReference]) ifTrue: [ sel setClassAndSelectorIn: csBlock ] ifFalse: [ selString := sel asString. i := selString indexOf: $(. "Rearrange to <className> [class] <selectorName> , and use MessageSet" classAndSelString := (selString copyFrom: i + 1 to: selString size - 1) , ' ' , (selString copyFrom: 1 to: i - 1) withoutTrailingBlanks. Smalltalk tools messageSet parse: classAndSelString toClassAndSelector: csBlock. ]. parse: methodRef toClassAndSelector: csBlock "Decode strings of the form <className> [class] <selectorName>." | tuple cl | self flag: #mref.

[Pharo-project] default window menu
by Tudor Girba Sept. 17, 2011

Sept. 17, 2011

Hi, Every window comes with a default menu. Most actions are useless or they can be found in the halo anyway. But, the window menu is not harmless: even if a window does have a specific set of actions (not just the default ones), the user is not informed because the same triangle appears in all windows. As an example, look at the Transcript and at the Workspace. The Transcript menu is useless, while the Workspace one is not. Glamour no longer offers this by default. Only if you have a window specific menu, you get it there. Like that when you see the triangle, you know it has a meaningful set of actions for you. I would suggest making this a default behavior for all windows. Cheers, Doru -- www.tudorgirba.com "Speaking louder won't make the point worthier."

[Pharo-project] MethodWrappers for Squeak 4.2
by Eliot Miranda Sept. 16, 2011

Sept. 16, 2011

Hi All, I've completed porting MethodWrappers to Squeak 4.2. You'll need to update your image to at least Compiler-eem.215 & Kernel-eem.623. You can find MethodWrappers4.2-eem.17 at http://www.squeaksource.com/MethodWrappers. Enjoy. P.S. Anyone in VW land interested in updating the codee? The class comments in VW are obsolete (valueNowOrOnUnwindDo: is mentioned instead of ensure: etc). If you do update the code you might want to add the tweak I did to MwBlockMethodWrapper>valueWithReceiver:arguments: to make both before and after blocks optional. i.e. MwBlockMethodWrapper methods for evaluating valueWithReceiver: anObject arguments: anArrayOfObjects "Optionally evaluate beforeBlock before evaluating clientMethod if beforeBlock is non-nil. Optionally evaluate afterBlock afterwards if afterBlock is non-nil." self wasActive: true. self beforeBlock ifNotNil: [:beforeBlock| beforeBlock value: anObject value: anArrayOfObjects]. ^self afterBlock ifNil: [self clientMethod valueWithReceiver: anObject arguments: anArrayOfObjects] ifNotNil: [:afterBlock| [self clientMethod valueWithReceiver: anObject arguments: anArrayOfObjects] ensure: [afterBlock value: anObject value: anArrayOfObjects]] On Tue, Sep 13, 2011 at 2:42 PM, Eliot Miranda <eliot.miranda(a)gmail.com>wrote: > Hi All, > > the most up-to-date MethodWrappers I can find is for Squeak 3.9, > pre-closures.

[Pharo-project] Zodiac Alpha - September 13, 2011
by Sven Van Caekenberghe Sept. 16, 2011

Sept. 16, 2011

I uploaded a modified PharoOneClick 1.3 app for Mac OS X, Linux and Windows to make it easier for others to test Zodiac, an as yet unfinished attempt at a better (secure) socket stream, in order to support HTTPS. This is a 40Mb download. The included VM contains the necessary native SSL plugins for each platform. The image itself was built as follows: ---- "Started with a standard Pharo One Click 1.3 #13306" Gofer it squeaksource: 'ZincHTTPComponents'; package: 'Zinc-HTTP'; package: 'Zinc-Tests'; package: 'Zinc-Patch-HTTPSocket'; load. Gofer it squeaksource: 'Zodiac'; package: 'Zodiac-Core'; package: 'Zodiac-Tests'; load. Gofer it squeaksource: 'ZincHTTPComponents'; package: 'Zinc-Zodiac'; load. "Switch to the Zn Zodiac socket factory" ZnNetworkingUtils default: ZnZodiacNetworkingUtils new. "Note: all http(s) in the image will now go through Zodiac streams" "** Make sure to use a Mac OS X Cog VM with the SSL plugin **" "Run the units tests, or just try" ZnClient get: 'https://encrypted.google.com'. --- Normally, all tests pass on Mac OS X, on Linux #testGForceInria fails, on Windows additionally #testAmazonAWS and #testPayPal fail. Additionally, #testSlashdotGzipChunked from the regular Zn sometimes fails because the server that is tested sometimes returns an unexpected answer (actually the test is not very good). Sven

[Pharo-project] Minimal buildable Pharo image with GUI?
by Dimitry Golubovsky Sept. 16, 2011

But I need to understand where the starting point is. Say, I pick a bare PharoKernel, and load it into a VM (headless) with a script like this (I hope Gofer it is there, but if it's not, what else to use?): "-------------------------------------------------------------------------------------------------" Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfXXX load. ((Smalltalk at: #ConfigurationOfXXX) project version: 'X.Y') load. (Smalltalk saveAs: 'minimal.image') ifFalse: [ Smalltalk snapshot: false andQuit: true ] "-------------------------------------------------------------------------------------------------" This is a variation of LoadVMMaker.st which is used to load the VM building stuff into Pharo Core. What XXX (packages) are needed to be loaded to get at least minimal GUI? Now, if in headless mode something fails, where will I see the error dump? Thanks. Anyway, in the light of Android usage, such specialized images will be needed for one-tap installable applications. -- Dimitry Golubovsky Anywhere on the Web
