How to start Squeak under WinXP from image on network?
by Ned Konz 05 Feb '04

05 Feb '04

I just installed the downloadable version of Squeak 3.5 on a Windows XP machine. I can start Squeak on local images (i.e. on the C: drive). that is, this works from a cmd prompt: cd /d c:\squeak squeak.exe squeak.image I tried to open an image several ways, but am not able to start up images on network shares. For instance, this doesn't work: c:\squeak\squeak.exe \\ned\homes\Squeak\3.6\squeak.image even though I can in fact see the image file in the explorer. Squeak complains that it can't find the file. Why doesn't this work? If I map a drive it works, though very very slowly: map h: \\ned\homes c:\squeak\squeak.exe h:\Squeak\3.6\squeak.image But I was trying to avoid mapped drives, since they seem to be just "tacked on" to NT (i.e. they have to go through a translation to become native resource names, etc.) and they're something else that can break. -- Ned Konz http://bike-nomad.com GPG key ID: BEEA7EFE

[BUG] TextPropertiesMorph - overflow
by Webb McDonald 21 Jan '04

21 Jan '04

If you have a text that's substantially large, opening a TextPropertiesMorph to add color becomes impossible. The window opens as large as your full text - is there an alternative? I believe it needs a scrollbar! Can I make this fix and turn it in? also - GeeMail gets blown away when you open TextPropertiesMorph... but I'm not sure where its best to begin with this, (it could call for a rethinking of TextPropertiesMorph - make edits to the existing TextMorph instead of a tmp copy? - evidently this problem with GeeMail occurs btwn the transition from 'TextPlusMorph', to tmp TextMorph, and back to TextPlusMorph). If no one has an opinion on this then I'll go ahead and do these changes! (or please inform me otherwise) - adios, Webb McDonald 1324481.14 662809.63

[FIX][REPOST] slightProgress-sm
by simon＠joyful.com 16 Jan '04

16 Jan '04

I file this in to every new image to get more accurate project loading progress bars, and it still works for me. So I thought I'd repost. from preamble: "Change Set: SlightProgress-sm Date: 3 Nov 2001 Author: Simon Michael Make project loading progress indicators slightly more accurate by storing timing data separately for local & remote downloads. After loading a few projects you should notice less flickering, especially when downloading large projects over a slow link. Also fixes the spelling of the TranslucentProgressMorph class."!

[Bug] The ever-widening PluggableTextMorph
by Ken Causey 31 Dec '03

31 Dec '03

( PluggableTextMorph on: nil text: nil accept: nil readSelection: nil menu: nil ) extent: 50@100; editString: 'This is some really long text that will hopefully cause the PTM to wrap and a scollbar appear'; hResizing: #shrinkWrap; openInWorld. Now either extend the text or just wiggle the scrollbar and watch the PluggableTextMorph widen and widen. The hResizing: #shrinkWrap seems to lead to this behaviour. Ken

[ENH] FileListEmptyDirectoryFix #2
by steve＠swerlingphoto.com 14 Oct '03

14 Oct '03

from preamble: "Change Set: FileListEmptyDirectoryFix Date: 28 December 2002 Author: Steven Swerling Currently in the hierarchy list FileList2, all folders have toggles that make them appear to have subfolders. This changeset removes the toggle from folders that do not contain subfolders. The old behavior of assuming that a subfolder exists is maintained in cases that would incur a performance hit (such as nonlocal directories). Changes this version: Catch Error in #hasContents causes default behavior (assume subfolder) instead of walkback."!

[BUG][FIX] A Morph that rendered by a TransformationMorph is not saved correctly
by Kazuhiro ABE 14 Oct '03

14 Oct '03

Hi all, A Morph that rendered by a TransformationMorph is not saved correctly. In this case, it needs to save a renderer instead of itself. 1. make an Ellipse morph 2. write a following script: Ellipse turn: 5 3. tick the script 4. save this morph by 'save morph in file' menu of debug halo 5. load the morph by 'load as morph' menu from filelist. 6. tick the script again 7. OOPS!! File in the attached changes, now saving and loading will work. Regards, Kazuhiro ABE NISHIHARA Satoshi

[FIX] RelativeZipExtractFix-nk
by Ned Konz 12 Oct '03

12 Oct '03

This is a fixed version of the prior posting with this name. Doug noted that it was broken under Windows. from preamble: "Change Set: RelativeZipExtractFix-nk Date: 16 December 2002 Author: Ned Konz Version: 3.4b 16 Dec: This fixes a problem with re-opening a zip in an ArchiveViewer under Windows (by opening zips read-only), as well as fixing extraction with subdirectories under Windows. 13 Dec: This ensures that zip extraction relative to a given directory works properly, and should eliminate the infinite recursion noted on the Mac. It lacks AcornFileDirectory>>relativeNameFor: ; this should be added if necessary before adding to the update stream. "!

[FIX] WeakMessageSend2-nk-rw
by Ned Konz 12 Oct '03

12 Oct '03

from preamble: "Change Set: WeakMessageSend2-nk-rw Date: 8 December 2002 (v2) Author: Ned Konz and Rob Withers v2: Eliminated WeakMessageSendError; value* now silently returns nil if receiver or arguments have been GC'd. This defines a simple MessageSend where the receiver and arguments are held onto weakly. And it changes the NuBlue event registration to use the WeakMessageSends instead, so that subscribers can be garbage collected. "!

Distributed Squeak
by Michael van der Gulik 12 Oct '03

12 Oct '03

Hello Squeakers. After studying distributed systems, distributed algorithms, parallel programming, and the associated practical work at uni, I think I'm almost ready to tackle an ambitious project: Distributed Squeak. Okay, it's been done before. But I'm going to do it again, and better :-). This will be my master's project (although it still has to be formally confirmed), and I've got 6 months to do it (until November). At the moment, all my ideas are a bit hand-wavy, but I'll be digging in and designing lots of things once I've finished hacking the Minix kernel (another practical at Uni). See the homepage for the basic idea - http://dpon.sourceforge.net. More info will be added when I've managed to write it up. Basically what I want to do is make a distributed, multi-user Squeak "image" (although it wouldn't really be an image anymore). So instead of starting up Squeak locally, you'd start up a "client" and log into a network of Squeak servers on the Internet. Objects could be migratable, remotely invocable or replicated, depending on the implementation of each distributed object. The advantages should be obvious - collaborative development for one. SqueakMap wouldn't be needed because everybody is using the same "image" concurrently. I'll quietly not mention the disadvantages :-). I think it can be done. It's just difficult, not impossible. If anybody knows of any related existing systems or technology not mentioned on dpon.sourceforge.net, I'd like to know. Also, feedback on whether this is actually a sane idea is greatly appreciated before I waste 6 months of my life :-). Michael.
