[BUG] in Morphic Project, Scripts, Windows 2000
by Alex Peake 06 Oct '02

06 Oct '02

(Sorry for repeat, I have just been informed how to report bugs) Sqeak 3.2, last update #4956 No changes to downloaded image Windows 2000 SP3 1.8GHz, 500MB ram * Open, Morphic Project (follow Roladex example) * Add Book to Project * Add Text to Project * Blue click, "eye" menu to get Scripts * Select "miscellaneous" * Select Book - do menu item * Add to Project ---------------- OK so far ? Yellow (quick) click on up/down arrows does nothing? (quick -> same as will bring up world menu etc.) * Yellow click, pausing down, causes next selection (correct) * Yellow click, holding down, cuases swift scrolling through (correct) * Yellow click on the up/down box edge displays menu (correct) ? Yellow click on a menu selects (apparently) unrelated choice? (delete -> change layout inset, search for text -> GIF file)? Alex

[GOODIE] InterAction: clickable web screenshot
by Avi Bryant 06 Oct '02

06 Oct '02

This is a quickie PWS version of an app Colin Putney and I developed in Seaside to manage remotely deployed Squeak images. The InterAction PWS module presents the Squeak screen in a web browser as a clickable image map; clicks on the image will be translated to mouse down/up events, and a form field lets you generate keypress events. This allows you to, for example, poke around in a debugger when your web app unexpectedly hangs, or perform a "save as..." to snapshot a server image. InterAction uses the ScreenshotAction module. Attached is a rewrite that uses JPEGReadWriter2 for better performance. It's optional, but highly recommended. To use it: - fileIn InterAction.st and (if you like) ScreenshotAction.st - evaluate: PWS serveOnPort: 9000 loggingTo: 'pws.log'. InterAction setUp. ScreenshotAction setUp. - point your browser to http://localhost:9000/interact Cheers, Avi

Actually, we took exactly the opposite approach. Not the OSKit or Linux approach. We've implemented all the drivers in Squeak. We're handling interrupts (all of them, except the clock IRQ) in Squeak, via a Semaphore that is signaled in a generic IRQ handler in the VM. We've implemented drivers for the serial port, keyboard and PS/2 mouse. We have classes with names like PIC8259 (the Programmable Interrupt Controller), PCKeyboard, UART8250, UART16550, etc. This is crazy, I know, it's a lot of fun. It is great to be able to speak directly to the hardware objects from Squeak, sending them messages and making it crash sometimes :) It's funny that you mention the project of writing a TCP/IP stack in Smalltalk from scratch. I've been doing exactly that in my spare time, and it works, or kind of (ARP, IP and UDP are working fine, and TCP is almost there, but with no fany stuff like delayed ACKs). We implemented SLIP over the UART8250 and were able to ping SqueakNOS from a Linux box. But please don't compare this homegrown OS to the Interval SqueakOS. We're four or five persons (from Argentina) working on our spare time, and the last time we got together to do put some work on SqueakNOS was like 6 o 8 months ago.

Re: SqueakMap 5:th release!
by danielv＠netvision.net.il 05 Oct '02

05 Oct '02

Okay, I just posted the latest version as described in the email. I also posted a change to make the World>open menu dynamic. This is important so that package can add themselves there. I posted these as ENH, and would really like people to test them - as far as I know, they're in good enough shape to be added into the 3.2 update stream - I've tested loading them into a fresh 4956 + SqueakMap release 5 (don't forget it's included fix), and everything loads find (and even unloads fine...) BTW, Goran, it'll be easier for people to test things if you could could make two separate one file releases for the model and the browser...

Components for Squeak?
by Aaron J Reichow 05 Oct '02

05 Oct '02

Hola kids, As a person who uses Squeak as his desktop, I'm always adding little things. Lately, I added some kb shortcuts to open a browser window (a Mac OS browser via applescript or failling that, Scamper) and to open a browser with a google search on the highlighted text in a PTM. This led to an email I was writing about a way to get a Services system (like in NeXTSTEP and now OS X) into Squeak. Adding lines to ParagraphEditor>>#initialize*Shortcuts is all fine and good for a hack, but it isn't scalable for anything outside of one dude's tinkering. But a Services system is just part of something bigger- componentish objects in Squeak. How can we make things more pluggable? Modules don't seem the answer- I've been told that modules must hold at least an entire class, you could just have a new version of a method (ala "Applications" [eq. to squeak modules] in IBM VisualAge Smalltalk). As an aside: Is this really the case? Would it not be possible to create a module, for example, that simply added a new category onto Object that provided a component protocol? Regards, Aaron Aaron Reichow :: UMD ACM Pres :: http://www.d.umn.edu/~reic0024/ "a system based on exchanging products inevitably channels wealth to a few, and no governmental change will ever be able to correct that." :: daniel quinn

[ENH] DynamicOpenMenu
by danielv＠netvision.net.il 05 Oct '02

05 Oct '02

from preamble: "Change Set: DynamicOpenMenu Date: 5 October 2002 Author: Daniel Vainsencher This converts the World>open menu to be have a dynamic portion. Celeste and IRC, being removable appliactions are removed from the static portion. Requires the implementation of three trivial methods in clients - the GUI class initialize should registerOpenCommand:, it's removeFromSystem should unregisterOpenCommand:, and it should have some unary message to open the GUI."!

[BUG] Abandon Sources Failure in 3.2
by cole＠nimiqinc.com 05 Oct '02

05 Oct '02

Hi, In trying to deliver a small application based on 3.2 I found that I am unable to successfullt abandon sources. The failure comes with a syntax error in Morph events-processing MouseDownPriority: mouseDownPriority (self isPartsDonor or: [self isPartsBin]) ifTrue: [^ 50]. ^ 0. End of block expected ->self flag: #workAround I checked this in a stock 3.2 image and was also unable to abandon sources (but did not get exactly the same error message). Any ideas? Michael
