Hi all, this tiny goodie removes all entries without references from Undeclared. Maybe this should be called after every file in.

[ENH] new String modifier: String>>asPlural
by Norton, Chris 24 May '04

24 May '04

Hi Folks. Here's the preamble from my changeset: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "OK. You could say that this is a silly crusade, but I like my Squeak messages to be in proper English (at least when the language you're using is English). I was messing around with the HangMan file-in and I got a walkback that had the following title: 'Error: HangManPhrases classs are not indexable'. I just couldn't stand the extra 's' on 'class', so I created a nifty new String method called asPlural and I modified the sender of the odd string to use the new String modifier. Take it or leave it, but I think this makes auto-generated text just a little easier to read." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I hope you find this new String modifier useful too. Cheers! ---==> Chris <<PluralStrings-ccn.cs>>

[ENH] SerialPort, remember them?
by David N. Smith (IBM) 10 Sep '01

10 Sep '01

Hi: I've been playing with serial ports on my Powerbook G3 and I discovered some not so nice actions in class SerialPort. If the port is in use elsewhere, trying to open it gets a Primitive Error. I'd rather have my code get back some indication that the port didn't open, so I made some small mods to SerialPort, which are attached. Basically, primitives used during open answer nil if they fail, and the open method answers nil also. Dave _______________________________ David N.

SyntaxHighlighting on 3.0
by Aron Brener 05 Jun '01

05 Jun '01

When I was using version 2.7 I used SyntaxHighlighting to highlight my code. I upgraded to 3.0 and loaded it into my image. It worked ok for a while but not it gives me a mnu #writeOnScan: Is there a version of SyntaxHighlighting compatible with 3.0? Or some other package that is similar that I could use?

Others have said the same. But the same benefits could be obtained from coloured borders, especially if there were a new kind of corner. The new kind of corner is rounded on the inside like rounded corners, square on the outside like square corners. This gives you a little "gusset" of border colour, quite noticeable. "Pretty-print with color" looks rather ugh against a hospital-green background.

Re: Fog Browser: Limiting or focusing browsers
by Stephane Ducasse 01 May '01

01 May '01

I originally tried to provide a different systemOrganizer to the borwser. However, wehen compiling a new method the current systemOrganizer was not modified. I browsed a bit around without really finding what I wanted. Does anybody knows if SystemOrganization is directly? Apparently I also made a confusion between SystemOrganizer and Smalltalk. I was wondering why I should work in a different namespace, environment (Smalltalk) and not in a different SystemOrganizer? I'm certainly worng but if somebody can say it this would help me. on 4/25/01 6:27 AM, Les Tyrrell at tyrrell(a)canis.uiuc.edu wrote: > > ----- Original Message ----- > From: Ned Konz <ned(a)bike-nomad.com> > To: <squeak(a)cs.uiuc.edu> > Sent: Tuesday, April 24, 2001 7:20 PM > Subject: Re: Fog Browser: Limiting or focusing browsers > > >> On Tuesday 24 April 2001 15:08, Les Tyrrell wrote: >>> If the regular Browser were consistent in always asking for "self >>> environment" or such instead of "Smalltalk", then this would be trivial to >>> do. >> >> And this is also needed (for instance) for Pocket Smalltalk and other >> projects that use the standard browsers with considerably different >> environments. > > Yes- this is how Oasis is able to use VW 3.0's regular Browser, although with > a few minor > modifications to it ( an "environment" instance variable had to be added, and > accessors adjusted > accordingly- other than that, the rest of the thing was ready to go as it was > ).

latest and greatest iPAQ Squeak?
by Craig Latta 01 May '01

01 May '01

Hi-- So, what's the latest and greatest Squeak system for the iPAQ 3600 series, and where can I get all the bits (build environment and image/changes/sources)? I'm interested to know how the Linux and WinCE versions stack up now performance-wise... I checked the "Squeak on the iPaq" page (http://minnow.cc.gatech.edu/squeak/1719), but it makes references to reasonability.net which seem to have gone stale. I'm willing to provide web space for bits cited (to replace my old 2.8-era stuff at http://netjam.org/smalltalk/sources/wince/ipaq.zip and http://netjam.org/smalltalk/sources/wince/squeakCE.zip). I just got a folding keyboard for my machine so I'm eager to start using it for serious hacking. :) thanks! -C -- Craig Latta composer and computer scientist craig.latta(a)netjam.org www.netjam.org crl(a)watson.ibm.com Smalltalkers do: [:it | All with: Class, (And love: it)]

Richard, > That's not switched, that's the way it is SUPPOSED to be. Only for people who think that Squeak in fact *is* the "original Smalltalk 80". I bet most of the newcomers don't and personally I'd be quite dissappointed if they would ;-) > It would be *very* confusing if Squeak had the mouse > buttons switched, thank goodness it doesn't. Thank goodness it *does* ;-) At least on Windows the default is to reverse the buttons. Why?! Simply because it doesn't make sense to put the secondary function onto an often non-existant mouse button. Cheers, - Andreas

I realized that the "yellow" (middle) and "blue" (right) mouse buttons are switched: the middle button brings up the context menu and the right button the window manipulation icons. That's not switched, that's the way it is SUPPOSED to be. If you look at the original Smalltalk-80 books, you'll find left = red middle = yellow right = blue (chapter 1 of the Orange book, for example). It would be *very* confusing if Squeak had the mouse buttons switched, thank goodness it doesn't.
