Renaming classes
by Ross Boylan 27 Aug '05

27 Aug '05

To migrate to the newer versions of squeak I'm going to need to play some games with class definitions. There are various scenarios; basically I need a good understanding of class definitions, renames, and the relation of these to class instances. I'm hoping for some tips that might save me some time pouring through the code; I don't see much about this on the wiki. First scenario: I have a class A and instances. I file in a changeset which defines A (suppose its the same definition). Does everything just work? Do I end up with instances pointing at an object which is the old class A? Second scenario: I file in a new class B, which is identical to A except in name. I want to make all the A instances become B instances. I want to make methods that refer to B refer to A. How? This involves DateAndTime and friends; the file-ins also do clever things to swap new and old definitions of, e.g., Date (e.g., changeset 5668). I notice they do some hunting around through (compiled?) methods too. My image has a DateAndTime class that is similar, though maybe not identical, to the one in the official file-ins. It also includes classes like DTDate which are similar to the "new" Date after the fileins. For reference, here's the postscript of 5668: "Postscript: Rename temporary classes TDate, TTime andTTimeStamp to Date, Time and TimeStamp." | jdn | jdn _ SystemVersion current date asDate julianDayNumber. #(#Date #Time #TimeStamp) do: [ :s | | zname tname | Transcript show: (Smalltalk at: s) allInstances; cr. zname _ ('Z', s) asSymbol. tname _ ('T', s) asSymbol.

pending mac VM 3.8.8b7 for comment
by John M McIntosh 26 Aug '05

26 Aug '05

I've posted a 3.8.8b7 Mac carbon VM to ftp.smalltalkconsulting.com Squeak 3.8.8beta7.app.zip I have not posted one to my idisk yet because of connectivity issues at ESUG. Like Squeak 3.8.8b6 this VM uses Quartz drawing versus QuickDraw as it's method of drawing the Squeak display bitmap to the window. This change is driven by VM changes needed for native Intel based macintoshs. However with 3.8.8b6 I discovered it did not work with Quartz Extreme. This VM changes the draw logic, and greatly optimizes it for Quartz and Quartz Extreme. The source code changes have been checked into SVN. Mac users should confirm: a) It works with 16 or 32 bit screens, and images set to 1/4/8/16/32 bits. b) That the drawing appears quickly and there is no lag time between drawing and user interaction. c) That it gives good drawing performance on earlier versions of os-x (versus 10.4). PS I will note one artifact: a) Weird drawing when you resize the window as Squeak is a bit confused about the real screen size for a few milliseconds and that is reflected in a screen update which then is fixed as Squeak resizes the Squeak window. -- ======================================================================== === John M.

[Swiki Question] Swiki RSS Feed and accented vowels
by German Arduino 26 Aug '05

26 Aug '05

Hi: I've posted this same message on the Swiki list, but permit me to post here also, being that more people seems to read this list. -- I'm implementing the RSS feed to my swikis, as is explained at: http://minnow.cc.gatech.edu/swiki/115 All is going ok, but in the rss page (http://www.myswiki.com/rss) I get in bad format the accented vowels (ב-י-ם-ף-ת) and another spanish specific characters (as ס). Normally this can be solved using #squeakToIso but I can't figure out were to apply it. I've tried in the templates that I've added (those of http://minnow.cc.gatech.edu/swiki/115 page) but seems not work. At swiki level, the accented vowels are displaying ok, without problems, but not at the rss page were are not displayed correctly.. Any help will be appreciated. gsa.

mp3 without libmpeg3-plugin possible?
by Stefan Krecher 26 Aug '05

26 Aug '05

Hi, while I was playing around with an MP3File-Class to extract ID3-Informations from MP3-Files (I put it into squeaksource at http://www.squeaksource.com/@iKpsUGECmmHGEwGO/TAoxlOhS), I asked my self if the MP3-Algorithms could get re-implemented in Squeak instead of using the libmpeg3-Plugin. Has this ever been discussed? Has anybody started doing something like that? Am I not seeing any problems or pitfalls? regards, Stefan -- GPG fingerprint = 2E77 C256 47B1 27B8 AE07 94BE D7A1 2A3C C716 2BE9 GPG public key: http://krecher.de/pubkey.asc ICQ #84067348 "A specter ist haunting the modern world, the specter of crypto anarchy" The Crypto Anarchist Manifesto, Timothy C.
