spontaneous menu change
by Chris Crowley 29 Nov '04

29 Nov '04

Hello: I'm using squeak3.7 (this issue happened w/ 3.6 as well.) I'm using a workspace window to test code: I type in the workspace, select the code I typed, and then click on the middle/wheel mouse 'button' and choose "copy", "paste", "do it", "print it" etc. from the usual menu that pops up in this context. Every so often however (at least once a coding session), the usual menu doesn't pop up, rather the 2nd page of this menu pops up, and there's no way to get back to the 1st page, since nothing is selectable. When this happens, the world menu changes as well, and nothing is selectable from it either. After a while, this "bug" corrects itself or I inadvertently do something that corrects it. For instance, I went away from squeak and typed this, came back, and the usual "do it" "print it" etc. menu popped up just fine. The next time it happened I went away to continue this email, returned to squeak, and the problem hadn't healed itself. But on returning to squeak a minute later it was fine again. Anyone encountered this and have an insight? Chris.

Problem: Cannot access SqueakMap
by Ruben Bakker 28 Nov '04

28 Nov '04

I don't know if this is the right place to report the problem, but the SqueakMap can't be reached from either the web or squeak since about 10 hours. I get the following browser error: ------------------------------------------------------------------------------- Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /sm. Reason: Error reading from remote server Apache/1.3.26 Server at map1.squeakfoundation.org Port 80 ------------------------------------------------------------------------------- Note: I don't use a proxy server...

Point me to the docs for threads
by Ryan Zerby 28 Nov '04

28 Nov '04

For my game, I'd like the AI to run in the background for X number of seconds. I don't want it to lock up the UI while it's thinking. In other languages, I've done this by firing off the AI as a thread, then creating another clock that sent a "stop" message to the AI after X seconds. I see implementing the clock as a Delay class.. but need a bit help figuring out the details of forking off the original AI process. Can someone point me to docs or examples?

Bug tracking
by Michael Rueger 28 Nov '04

28 Nov '04

Hi all, we just moved the bug tracker (bugs.impara.de) to a new server/IP address. While the domain change is propagating through the DNS we have established a forwarding proxy. We also moved to the newest Mantis version, so a few things look a little different. The new version also suports web services, for those of you who would like to integrate bug tracking directly into Squeak/Croquet. Let me know if there are any problems! Cheers Michael

Which graphics package to use?
by Ryan Zerby 28 Nov '04

28 Nov '04

I'm writing my first real squeak program, Mancala (My favorite game to program for some reason :) I'm thinking that I want to use Morphic for my first version of the interface (yes? no?) I see all of these other cool graphics packages as well, and am a smidgen overwhelmed about what I would want to use should I decide to code a 3D interface (perhaps something that would look neat in croquet). What package should I be aiming to use (and why?) . I see my loftier goals as making applications for squeak as a tool for wearable computers. I'll want something that can support both an overly (for 2D information, HUDs, etc) as well as reasonably realistic 3D (for data that is interactive with the environment.. flat shading would be enough, but I'd prefer something more). Thanks!

[OT?] Fw: [ANN] IA32FVM + HPK (Headless Pure Kernel) image
by SmallSqueak 28 Nov '04

28 Nov '04

Dear Squeakers, Please consider this as my little contribution to the NRTF. At least to me, for now, I can enjoy the idea that I have a Headless Pure Kernel (tm) image with a VM stuckin. (all in 40 'forthy' KB ;-) My hope is that this will become a topic when the future is going to be invented ;-) Cheers, SmallSqueak. ----- Original Message ----- From: "PhiHo Hoang" <phihoDOThoang(AT)rogersDOTcom> Newsgroups: comp.lang.forth Sent: Thursday, November 25, 2004 11:20 PM Subject: [ANN] IA32FVM + HPK (Headless Pure Kernel) image > Greetings, > > This was posted last weekend and it seems it was burried under the > old thread "Forth VM + microKernel" . > > Since I really like to get feedback on the exercise I started several > weeks ago and just barely finished last weekend, I am reposting this > under a new thread in the hope that it can draw some attention hence > feedback. > > Please accept my apologies if anyone find this reposting offended. > > [SNIP] >> >> >> Only recently he thinks he found an interesting use for Forth so he is >> trying to do a more serious exercise, turning Win32Forth kernel into >> a pure STC kernel for IA32 architecture and the wrapper into a thin >> wrapper with minimal C code to support system interface through >> dlfcn interface and some other things. >> > > The changes to STC will come later.

Is there any P2P/distributed file system work going on in squeak? Thanks, P.

SmaCC
by Jason Rogers 27 Nov '04

27 Nov '04

I am exploring the SmaCC package (using it to parse Java source files), but I am greatly lacking in my understanding of parsers and scanners. My question is hopefully a simple one... Once I have parsed or just scanned the source, what can I do with it? There is a collection of SmaCCTokens returned via JavaParser class>>parse: but I don't know what to do with them. They seem to be coded in some way but I have no idea how to interpret the codes. Does anyone have a short tutorial they can point me to? The pages on the SWiki aren't very helpful and the tutorial on refactory.com isn't very helpful either. -- Jason Rogers "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me." Galatians 2:20

Where would I post a BIG project?
by Joshua Scholar 27 Nov '04

27 Nov '04

Microsoft Word is putting Japanese text into the clipboard in unicode format in English environment Windows instead of using Shift-JIS. Probably the IME is entering unicode too. Joshua Scholar
