[UNIX][VM] network audio support
by Lex Spoon 30 Sep '01

30 Sep '01

I've dug into "NAS" (Network Audio System) and added some basic support to Squeak on Unix. The reason this is useful is that multiple programs using NAS can share the audio device, plus they can access audio across the network. This matters if you run programs other than Squeak that use sound, which as you might guess I do. :) http://minnow.cc.gatech.edu/squeak/uploads/298/Squeak-lex.6.tgz or for the individual patches: http://www.cc.gatech.edu/~lex/squeak (wait until tomorrow morning for this to update) This driver doesn't support as much as my OSS driver does; it doesn't have recording, and it doesn't have volume control. But it might be enough to interest some people. Along the way, I've rearranged the sources a little so that you can more easily add new audio drivers. So if somebody wants to shoot for ESD or ARTS or whatever else, go for it! -Lex

[BUG] Relative directory strangeness?
by Ned Konz 30 Sep '01

30 Sep '01

/home/ned/tmp is an empty directory. /tmp/xx.txt exists and is a file. d _ FileDirectory on: '/home/ned/tmp'. d fileExists: 'tmp/xx.txt' "true, but shouldn't be" d fileExists: './tmp/xx.txt' "true, but shouldn't be" d fileExists: '/tmp/xx.txt' "true" d fileExists: '/home/ned/tmp/tmp/xx.txt' "false" It seems to me that there should be some way to test for the existence of arbitrary files even in subdirectories. I think that d fileExists: 'tmp/xx.txt' and d fileExists: './tmp/xx.txt' should both return false. Anyone else got an opinion on this? -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com

Re: [modules] Ginsu in 3.1

Hey guys, We need to be more organized about this - part of the changes you enumerate are included in the ones I posted on the 23rd. The other things I did - * Give treatment 4 you describe to referencedClasses in the same class. Compile - MethodDefinition>>testLiterals self assert: (defn literals anySatisfy: [:e | e isVariableBinding and: [(e key = #Halt) & (e value = Halt)]]) BTW, you can just cut out the extra arguments on calls to ChooserMorph - they never did anything. They're out of whack with the RB, because I removed them there... ducasse stephane <ducasse(a)iam.unibe.ch> wrote: > Could you poste your version on the squeak Foundation wiki ;) > I was planning to do that but I'm ___really___ overloaded.

Skip List in #4308
by merlyn＠stonehenge.com 30 Sep '01

30 Sep '01

Skip lists got snuck in with changeset 4308 with *no documentation* except the source code. Not even a class comment! Can SqueakCentral at least set the bar high enough that *new* classes into the core will not be accepted without at least having a class comment? Please? Especially something that is in the Collections category! -- Randal L.

Desired Archive behavior w/r/t absolute paths?
by Ned Konz 30 Sep '01

30 Sep '01

The Zip archive format allows absolute pathnames (i.e. those starting with '/'). Most people don't use them, but it's generally possible to do so (possibly inadvertently). My ArchiveViewer allows extraction of all the files in an archive (which may have a mixture of absolute and relative names) into a particular directory. The obvious way to handle this is also a potentially dangerous one: use the given directory as the root for the relative files, but extract the absolute ones to their desired path. i.e., if you have an archive with the files (trailing / denotes a directory): /a/ /a/b c/d/ c/d/e and extracted to /tmp, you would get: /a/ /a/b /tmp/c/d/ /tmp/c/d/e Under Unix and some Windows NT systems, file permissions may protect files you don't own from being clobbered. The other obvious way to handle the problem is to make all files relative whether or not they started out that way in the archive, so we'd extract the above as: /tmp/a/ /tmp/a/b /tmp/c/d/ /tmp/c/d/e If you wanted to extract to the root, of course, that's up to you and your filesystem security. I'm leaning toward the second strategy; does anyone have a preference on this that they'd like to share? -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com

Hi squeakers! After loading a new image (3.0 and 3.1 alpha) the byteSize of the Win32Rectangle returns 0 but should return 16. To correct the compiledSpec (field definition) type Win32Rectangle compileFields. keep squeaking Gerald.

RE: Squeak BOF at OOPSLA
by Doug Way 30 Sep '01

30 Sep '01

Looking forward to the BOF (Birds Of a Feather) session at OOPSLA. Maybe I'll try to keep the informal Squeak "bug fixing party" going at Camp Smalltalk there this year, too. Just a quick suggestion to anyone going to OOPSLA who hasn't booked a hotel room yet: I was originally going to try to find a somewhat cheaper hotel downtown than the suggested ones (which had "special" OOPSLA rates of $140-$150 per night), such as the Holiday Inn several blocks away for about $100. But then I happened to try priceline.com, and set a price of $50/night for any 3-star hotel, and it actually reserved the Marriott Waterside (adjacent to the conference, originally $150)! (This was for Sat.-Wed.) - Doug Way dway(a)riskmetrics.com -----Original Message----- From: Dan Ingalls Sent: Fri 9/21/2001 2:22 PM To: squeak-dev(a)lists.squeakfoundation.org Cc: Subject: Re: Squeak BOF at OOPSLA >What do people know of other activities on Tuesday night? It would be great to start the BOF at 7pm, but we could slide a bit later if there are serious conflicts. Just to follow up, for those of you attending: I have made a request for a room from 7 to 9 on Tuesday evening, with a provision that we might slide it later in case of conflicts. I'll confirm what we know for sure the week before the conference. Perhaps someone active on comp.lang.smalltalk could forward this preliminary plan. Thanks - Dan --

Re: [ENH] A new way to manage collapsed windows
by Russell Allen 30 Sep '01

Well, that was interesting :( What I meant to say, rather then forwarding Aaron's mail back to the list, was something like this: Aaron, The screenshot looks kinda groovy; it reminds me of BeOS. I notice that it was taken on OS X - did you consider creating a dock equivalent? It works for both windows and morphs (just drag them to minimise) and should be able to leverage existing flaps stuff...
