[BUG]FileUrl>default?
by Tim Rowledge 02 Dec '03

02 Dec '03

THe FileUrl>default method seems a rather poorly named little chap. Normally one would expect #default to be a class method to create a default valued instance. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Every program is a part of some other program, and rarely fits.

[ENH] ifEmpty-etc-jf
by julian＠beta4.com 02 Dec '03

02 Dec '03

from preamble: "Change Set: ifEmpty-etc-jf Date: 1 December 2003 Author: Julian Fitzell Ned submitted a fix back in September for several RB issues. One of the pieces of that fix was the set of ifEmpty/ifNotEmpty methods. There was some discussion and it was agreed that they should all take 0-arg blocks in all their forms and we could add #ifEmptyDo:, etc. at a later point if desired. No revised fix for these methods was submitted and they never made it in. So I wrote them up and here they are."!

[VM] pending change to Cross platform sq.h
by John M McIntosh 02 Dec '03

02 Dec '03

I'm proposing a change to sq.h such that /* image file and VM path names */ extern char imageName[] becomes char *imageName(void); The VM supplies an image name to the image open logic. This image name comes from the VM support routines once they decide what it should be as part of the startup process, or later when you do a save or save as operation. Having a function return a pointer to the characters as a result of calculations that determine issues like character encoding is 'better' than referring to an MacRoman ASCII byte string. This allows the os-x version to translate a unicode path name to the desired mapping when needed, since that mapping might change under Smalltalk application control. Yes, there will need to be a change set with this at some point to alter Interp.c to generate imageName() versus imageName -- ======================================================================== === John M.

An '*?%&$' mood
by raymondasselin＠sympatico.ca 01 Dec '03

01 Dec '03

1. Can somebody explains what to do (is there something to do?) when you install a package from SM and there is undefined classes lists on the Transcript window? Like : (SixxXmlUtil is Undeclared) (SixxXmlUtil is Undeclared) (SixxXmlUtil is Undeclared) (SixxXmlParseError is Undeclared) (SixxSetting is Undeclared) (SixxXmlUtil is Undeclared) (VWXMLXMLParser is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockBinaryData is Undeclared) (SixxMockBinaryData is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) (SixxMockClassForUnitTest is Undeclared) 2. And what to do with UndefinedObject when trying to install Refactoring Browser ! My image is 3.7 5566 and I want to try SmallWiki so I started with a clean 3.7 image... =========== 3. I must say that lots of things are harder to get together with Squeak from 3.6. It seems to me that this was'nt the case with the 3.5 release. Few examples: - At Job in WinNT4.0 I can't bring a 3.5 Squeak project (.pr) in 3.6 Squeak when trying to save it and load it in a 3.6 image there are problems. - It is the same when trying to save a 'drawing' in Connectors to be able to load it in a 3.6 image, or 3.7 one. - Recently there was problems with the MacOSX 10.3 and the VM - There is or was problem whith filePath in Mac don't know if this is fix, nor in which vm or image it is fix, nor if I need to install a patch and which in which image. - When I tried to use new version of Seaside with 3.6 Squeak, Seaside had changed, Comanche had changed, some package on SM try to load a Seaside version not anymore served.... - Did you tried to load BFAV to understand it and see if you can help in a minimal way the Squeak community...I don't know how it is now but two weeks ago this was a mess... ...so......fewwwww...!!! So: - projects from image to image is'nt stable.. - 'drawings' from image to image is'nt stable...(may be it is the same problem...don't know). - using SM is'nt stable yet (I know Göran.. the SM2 will be...). No, -- backtracking --, SM is stable but the documentation which say explicitly which package is a prerequisite an what is the loading order is'nt, so for the end user this is the same: the experience is'nt stable. In fact I lost at least 30 hours to try few things in Squeak and nothing was working the first time and often I did'nt know how to solve the problem. I don't mind about these hours but i'm a bit 'lost', I don't think it is possible to master all aspect of Squeak to use it, and I don't think I should understand it all to use it. BTW, I know what have been done in Squeak from 2.2 image, and thats a lot. In fact what is frustrating is'nt new 'alpha' stuff, it is the old one that didn't function any more in new version of Squeak. A part of the problem is mine as I should have been signaling every bug as a bug to the community, but this is time consuming when english is your first langage, and even more when it is not...this is why I tried to load and use BFAV. ========= Conclusion: - the effort to identify 'maintainers' for differents parts of Squeak will be a big improvment. I think that I now, master Smalltalk sufficiently to help but not to be a lead maintainer. - the SM2 is an absolute necessity (I know SM2 alpha is there but did'nt check it yet). - Sorry...I was in a '*?%&$' mood. Let come back to Squeaking. Raymond

VM file name character encoding support (pending)
by John M McIntosh 01 Dec '03

01 Dec '03

I believe that to support different file name character sets we're going to need to alter sqVirtualMachine.c and take VM_PROXY_MINOR to 6 by adding three new calls to support information about what the file name encoding information is. getVMEncodings returns Smalltalk OOPS Array of supported encodings which the VM supports. getCurrentVMEncoding returns magic integer signifying the encoding being used. setCurrentVMEncoding takes magic integer, returns 1 if set, zero if not a supported encoding. where the magic integer is and I'll be platform independent and define them as: MacRoman = 0, WindowsLatin1 = 1, /* ANSI codepage 1252 */ ISOLatin1 = 2, /* ISO 8859-1 */ Unicode = 3 UTF8 = 4 This allows plugins, like the mpeg plugin to accept a file name from the VM and know what to do with it before issuing the file open by asking the VM what the encoding is. It also of course allows a programmer the ability to see and choose an encoding to use within the Image. I'm also considering using a reserved header word in the image so we can determine what the image encoding is at startup time because things like the VMPath are loaded early and we can better ensure file name encoding is done correctly versus relying on some startup task stamping the image with the encoding information. What is unclear, but could be defined is how to deal with existing path information, such as the vmpath once you switch encoding. I suppose you could leave that information in native platform format and return a converted value based on the currently chosen encoding. Thoughts on this are welcome. -- ======================================================================== === John M.

[BUG] SM2 Burps after loading Jacaranda
by Thomas A Petersen 01 Dec '03

01 Dec '03

Goran et. al, Per your request, here is some SM2 feedback. Started with Squeak 3.7a 5566 Opened package browser using World | Open Loaded SM2 Loader It asked me if I wanted to define a MC related thing. I said yes. The install left some garbage on the display that I attribute the evil motherboard graphics on the machine I am using. I then reopened the package loader and attempted to install MC loader thinking it might be needed. It told me it was already there and when I cancelled giving the change set a new name, it gracefully failed to install. Now I told it to install Jacaranda. SM2 noticed I had not installed Connectors. I told it to go ahead. Things trundled a bit and it threw a debugger after putting up all of the extra flaps I was expecting. The debug log is attached. Hope this helps, tap P.S. Some of us do care. We just have day jobs and families that keep us away from the fun stuff.

#ifEmpty: and its brethren
by Julian Fitzell 01 Dec '03

01 Dec '03

Back in September, Ned submitted an ENH with some methods that are used by the RB. One set of methods were the #ifEmpty/#ifNotEmpty: variations. After some discussion, it seemed there was consensus to add these methods in forms that take 0-arg blocks as arguments (original message quoted below). Does this need to get posted as a new, separate ENH? I tried to check if it had already been put into 3.7a, but the 3.7a images are segfaulting my VM and I don't have time to figure out building a new one atm. I don't mind making and posting the changeset if desired, though because of the above I can't test it in the latest 3.7 right now.

[FIX] MiscCommentBugs
by bparsia＠email.unc.edu 01 Dec '03

01 Dec '03

from preamble: "Change Set: MiscCommentBugs Date: 19 November 2003 Author: Bijan Parsia Found some typos and bugs in some comments as I poke around. So, we need metacomments for these :) FileList2 class comment contains the line: FileList2 morphicViewImageViewer openInWorld But there is no such method in my 3.6 image. DELETED!! Form class>>openImageInWindow: had a typo for storeOn: Given the class comment in ImageMorph, I wonder if this method should be changed to return and ImageMorph rather than a SketchMorph, even though ImageMorph is less functional. (ImageMorph's class comment claims that it supercedes SketchMorph. The change is simple enough, i.e., change the ifTrue: branch of the last statement from '[(SketchMorph withForm: image) openInWorld]' to '[image asMorph openInWorld]' "!
