Squeak color question and comment...
by Serg Koren 05 Jan '98

05 Jan '98

I'm playing with some of the code from "A Taste of Smalltalk" and have a comment and question. First off it seems that Squeak doesn't implement the white: black: gray: etc. rectangle filling methods. I've gotten around this by just calling fillWhite:, etc from the DisplayMedium class. If anyone wants to pass on the actual definitions of white:, etc. I'd appreciate it. My question is why does 'invert'ing a white display (on the Windows version of Squeak) produce pink? I haven't looked into this yet, figured I'd ask if anyone knows...I was sort of expecting black.

Squeak *.sit bytestream question...
by Serg Koren 02 Jan '98

02 Jan '98

Hi, I'm finishing up an upgrade to the Mac version of Squeak's VM application and am trying to figure out how the bytestream for the included *.sit file was created. I've cleaned up the code and made it compatible with CodeWarrior Pro 2 version and have figured out how to get my code to generate cleanly (and recompile cleanly), but need to incorporate the Stuffit project file. To do this I need to convert the Stuffit file into a bytestream that Squeak can use. Anyone know how this was done? Once I can do this, I'll post the update on my web site. FYI the changes include: - Clean compile and build under CW Pro2 - Real resource file in the VM...it now has a real Squeak icon, etc. - Real About box. - A couple of Smalltalk examples (mostly from "A Taste of Smalltalk") Thanks, S ------------------------------------------------- VisualNewt Software: http://www.VisualNewt.com/ Maker of Newt'sPaper(tm) the Premier Newton(R) MessagePad(tm) News Reader. -----------Sent by BeOS--------------------------

BeSqueak & Mac Squeak 1.24SK web sites set up.
by Serg Koren 02 Jan '98

02 Jan '98

Hi, This is to let everyone know I've set up a couple of web pages related to two Squeak projects I've undertaken. The first is to upgrade the Macintosh Squeak VM application to be more Mac like and to get it to compile cleanly under the latest version of CodeWarrior; I've actually done this already. In addition, I've started porting Squeak to BeOS (http://www.be.com/). I'm currently in the process of porting the platform specific portions of the code. For more info, feel free to check out the following URLs: Mac Squeak 1.24SK - http://www.VisualNewt.com/Mac/Squeak124.html BeSqueak - http://www.VisualNewt.com/BeOS/Squeak.html Also, if anyone wants to contribute good Smalltalk examples (with significant comments) for inclusion, feel free to submit them to me for inclusion. I'll make sure you get credit in the code and readme files. For more info you can email me at Serg(a)VisualNewt.com Thanks, Serg Koren VisualNewt Software ------------------------------------------------- VisualNewt Software: http://www.VisualNewt.com/ Maker of Newt'sPaper(tm) the Premier Newton(R) MessagePad(tm) News Reader. -----------Sent by BeOS--------------------------

Some more details:- if you proceed at 2. , all is well. if you debug at 2. and then step over the halt but proceed from there, all is well if you you debug, step, then send the error: and proceed from the first message there in, all is well. if you go the same route but keep stepping, the system dies when stepping over the DebuggerView>openContext:label:contents: message. if you send this message instead of stepping over it, you can eventually get all the way down to ControlManager>scheduleActiveNoTerminate: and thence to scheduled:from: where stepping over 'self activeController: aController' crashes you .. This tallies reasonably well with observed behaviour when trying some of the earlier routes, since the debugger deEmphasises just before the crash. Since William sees an apparent failure on prim 88 (suspend) and I get to where a resume is sent, I have some suspicions about some sort of clash between suspend and resume when the process involved has been molested by the debugger. That's all I have time to spend digging for now, but hopefully it might help someone. tim -- Fractured Idiom:- RIGOR MORRIS - The cat is dead Tim Rowledge: rowledge(a)interval.com (w) +1 (650) 856-7230 (w) tim(a)sumeru.stanford.edu (h) <http://sumeru.stanford.edu/tim>
