SUnit debugging hint.
by rvclayton＠acm.org 30 May '06

30 May '06

When this test testStartSymbol self assert: lambda startSymbol = 'lambda' gets run by SUnit, it produces this yellow-bar error: ContextFreeGrammarTests>>#testStartSymbol Clicking on that line brings up the debugger with the following stack trace: ContextFreeGrammarTests(Object)>>halt ContextFreeGrammarTests(TestCase)>>openDebuggerOnFailingTestMethod [] in ContextFreeGrammar Tests(TestCase)>>runCaseAsFailure: {[self setUp. self openDebuggerOnFailingTestMethod]} BlockContext>>ensure: BlockContext>>sunitEnsure: ContextFreeGrammar Tests(TestCase)>>runCaseAsFailure: ContextFreeGrammar Tests(TestCase)>>debugAsFailure TestRunner>>debugFailureTest: PluggableListMorph>>changeModelSelection: PluggableListMorph>>mouseUp: PluggableListMorph(Morph)>>handleMouseUp: MouseButtonEvent>>sentTo: PluggableListMorph(Morph)>>handleEvent: PluggableListMorph(Morph)>>handleFocusEvent: [] in HandMorph>>sendFocusEvent:to:clear: {[ActiveHand := self. ActiveEvent := anEvent. result := focusHolder han...]} [] in PasteUpMorph>>becomeActiveDuring: {[aBlock value]} BlockContext>>on:do: PasteUpMorph>>becomeActiveDuring: HandMorph>>sendFocusEvent:to:clear: HandMorph>>sendEvent:focus:clear: My question is: how do I get to testStartSymbol's execution context? If I click on the first line (ContextFreeGrammarTests(Object)>>halt) the debugger puts me in halt "This is the typical message to use for inserting breakpoints during debugging. It behaves like halt:, but does not call on halt: in order to avoid putting this message on the stack. Halt is especially useful when the breakpoint message is an arbitrary one." Halt signal Clicking on the next line puts me in openDebuggerOnFailingTestMethod "SUnit has halted one step in front of the failing test method. Step over the 'self halt' and send into 'self perform: testSelector' to see the failure from the beginning" self halt; performTest None of the other lines are close to where I want to go. If I force a red-bar error by putting 1/0 in startSymbol, the debugger stack trace looks like SmallInteger>>/ ContextFreeGrammar>>startSymbol ContextFreeGrammar Tests>>testStartSymbol ContextFreeGrammar Tests(TestCase)>>performTest [] in ContextFreeGrammar Tests(TestCase)>>runCase {[self setUp. self performTest]} BlockContext>>ensure: BlockContext>>sunitEnsure: ContextFreeGrammar Tests(TestCase)>>runCase [] in ContextFreeGrammar Tests(TestCase)>>debug {[(self class selector: testSelector) runCase]} BlockContext>>ensure: BlockContext>>sunitEnsure: ContextFreeGrammar Tests(TestCase)>>debug TestRunner>>debugErrorTest: PluggableListMorph>>changeModelSelection: PluggableListMorph>>mouseUp: PluggableListMorph(Morph)>>handleMouseUp: MouseButtonEvent>>sentTo: PluggableListMorph(Morph)>>handleEvent: PluggableListMorph(Morph)>>handleFocusEvent: [] in HandMorph>>sendFocusEvent:to:clear: {[ActiveHand := self. ActiveEvent := anEvent. result := focusHolder han...]} and the second and third lines from the top give me what I want. Why the difference in stack traces? This is on squeak 3.8, update 6665 from a debian testing system.

There was a little mixing going on but basically everything morph wise I use is derived from my base morph which was derived from AlignmentMorph. I have tried changing that to BorderedMorph and quite a lot of behavior is different and possibly a little better but essentially what I said above is still the case. I can't get inner morphs to flow back once they have flowed out.

[ANN] Towards a new File In / File Out format
by Torsten Bergmann 29 May '06

29 May '06

Hi stephane, the SDK is available since I think ESUG 2002 and was rarely updated after that. The latest version from the website is v4.1.4.616 from June 2004. Even if some people complain about the slow progress it is available and usable (on Win32). I dont know how many people really played with the AOS SDK - maybe they expected (or still expect) a full commercial IDE system or a well maintained, documented open source system for all OS platforms. Don't know about it's future in general - it's like everywhere mostly a question of resources and time... Bye Torsten

Debugging through events
by Cowdery, Bob [UK] 29 May '06

Is there a way to debug or even put Transcript writes into event handlers like drawOn and extent. My attempts seem to hang Squeak.

SqueakSource questions
by Keith Hodges 29 May '06

29 May '06

In the squeaksource wiki can anyone tell me what is the best way of displaying source, particularly XML source. It says that XHTML tags are accepted, does this include the CDATA tag, could this be used, or can one disable XML markup temporarily. I did try this without success. Is there a way to cross reference to other wikis in SqeakSource easily, or do you need to use http:// I am thinking of using this wiki extensively, as I learn about squeak I plan to document my findings there, if I feel there are any pages that contribute to documenting squeak then I will tag them *doc* , or is there an accepted protocol for doing this. Finally, if you put < into the wiki it displays it as <, but when you edit the page again the source is now '<' not < as it should be. This kind of ruins any attempt to solve this displaying source problem. I thought it was standard practice in wikis to escape such things.

Morphic layout policy problems
by Bob.Cowdery＠CGI-Europe.com 29 May '06

29 May '06

Hi all I have a problem with morphic layout policies and I'm not sure if it's a feature, limitation or a bug or if there is something else I need to do. This can be reproduced very quickly using two AlignmentMorphs (Bordered or PasteUp will also do) and 4 SimpleButtonMorphs. Set AlignmentMorph 1 with left to right wrapping. Embed the buttons in AlignmentMorph 1. Adjusting the size of AlignmentMorph 1 causes the buttons to flow properly between horizontal and vertical alignment. Now size AlignmentMorph 1 until the buttons are in a vertical row and size AlignmentMorph 2 to be about the same size and embed AlignmentMorph1 in 2. Now sizing AlignmentMorph2 will flow the buttons progressively outwards until they are in a horizontal row but you can't flow them back in again. As usual any help appreciated.

Help with MC....
by Stéphane Ducasse 29 May '06

29 May '06

hi guys I really have little time now to integrate changes and harvest. I tried to find how I can get the list of the currently loaded packages in an image but I failed (ok I lost just 20 min for nothing). So I need help. Can someone tell me how I can get this information? I was planning to harvest a bit this evening but I will not, since I got stuck (Im fedup to spend my time checking number manually and producing errors). I think that if the community does not realize that we REALLLY need help then I wish you the best for the next versions. Stef

could we have the latest version of Spoon on squeak.org
by stéphane ducasse 29 May '06

29 May '06

Hi all Downloading spoon require bittorrent and a university not blocking port... So I would suggest that if we are serious about Spoon as a potential future for Squeak (I hope) we should have the latest spoon distribution on the squeak.org web site. Stef
