Project-specific preferences
by C. David Shaffer 02 Mar '04

02 Mar '04

Has anyone hacked together something to make the standard preferences project-specific? I searched the mailling list but don't see anything. I see that projects have "projectPreferenceFlagDictionary" but they don't seem that widely used. Things like colors and font sizes are often project-specific for me so I've written little scripts to swap preferences when I swap projects...it really isn't very convenient. Really this is rather a silly, low priority thing. I just like my tool colors to match my background :-) Assuming it hasn't been done, how's this for a quick way to make this work without having to rewrite all the references to Preferences....I could rename the Preferences class (without updating references), make a doesNotUnderstand: proxy, install it in Smalltalk at: #Preferences and have it look up the current project preferences to redispatch the message.

Different review process for KCP changes?
by Ken Causey 02 Mar '04

02 Mar '04

Göran has been doing some excellent detective work related to my reported issue with code corrections in the workspace. He has tracked it down to a change made in update 5700 (KCP136MoveChangesLog). The change does not seem to be related to the purpose of the changeset. This is bad enough but what really bothers me is that there doesn't seem to have been any opportunity to review this change. I've searched and searched and searched and it doesn't appear that this changeset ever appeared on the lists. A variant number 116 did and was closed. What happened? Is there some other route that KCP changes go through? Ken

[ENH] PNGReadWriter writing support & alpha fixes ( [er][su][et][approved] Use v7. )
by gohu＠bluefish.se 02 Mar '04

02 Mar '04

Hi all! I did the following: - Filed it into a virgin 5707. Noted I need to use Andreas version and then add Ned's single method fix. Not sure why Neds changeset didn't include the Test class definition. Then when I wrote this Andreas posted a v7 fixed accordingly, fine. :) That one also filed in cleanly in 5707. - Ran tests. All green. - Tested producing a .zip file and opening it too. Just to see if those things broke, it worked fine. Also uses this code in my BFAV image, which does gzipping/gunzipping. - Looked over the code changes but didn't analyze it. Noted the "Debugging" class var, but we can keep it for a while. Sidenote: Might be interesting to have a convention for such things. - Looked at the generated PNGs in XP viewer and Firefox. Didn't check all but they worked fine. Anyway, this is stuff from highly esteemed Squeakers, and it seems to have been tested a bit by other people too. And if we can't trust them then... :) regards, Göran

[ENH] Use of EndOfStream (sm)
by Boris Gaertner 01 Mar '04

01 Mar '04

This proposal is for Squeak 3.7alpha #5623 We have a resumable exception EndOfStream, that we do not use. The comment of that exception reads: 'Signalled when ReadStream>>next encounters a premature end.' but this is not true. In ReadStream>>next, we have: next <primitive: 65> position >= readLimit ifTrue: [^nil] ifFalse: [^collection at: (position _ position + 1)] To really use the exception hanlding mechanism, we have to replace the "^nil" with ^EndOfStream new signal. The default action of EndOfStream returns the value nil. This is compatible with the current behavior of method "next". It is therefore not necessary to modify the senders of this message. The attached change set contains this change for several kinds of streams. Greetings, Boris

Re: [FIX] FasterMouseOver-nk ( [sm][et][approved] )
by Andreas Raab 01 Mar '04

01 Mar '04

Hi Guys, Must have missed this post earlier on but I want to point out that this change will have side-effects. The current mechanism has been made so that even if morphs move they will be notified about mouse entry/leave events. E.g., if you have a little eToy that does something like: foo>>script1 [on: mousEnter] foo's color <- Color red. foo>>script2 [on: mouseLeave] foo's color <- Color green. foo>>script3 [ticking] foo forward: 5. foo turn: 5. then, upon having foo move under the cursor, the system will correctly invoke the event responses. With the changes proposed it no longer will. I can't say for sure what other implications this has but it's certainly an annoyance for eToys - in particular considering that #isUnderMouse will report true but no events are being generated. Cheers, - Andreas ----- Original Message ----- From: <marcus(a)ira.uka.de> To: <squeak-harvest(a)lists.squeakfoundation.org> Sent: Sunday, February 29, 2004 4:46 PM Subject: [FIX] FasterMouseOver-nk ( [sm][et][approved] ) > > No Conflicts.

[ENH] addHorzScrollbar
by sps2000＠mail.com 29 Feb '04

29 Feb '04

from preamble: "Change Set: scrollport Date: 28 December 2002 Author: Steven Swerling I was adding a horizontal scrollbar to the SimpleHierarchicalListMorph, but realized that many of the methods would be generic to any subclass of ScrollPane. And there were many methods. So I moved the changes up to ScrollPane. This changeset adds a horizontal scrollbar to ScrollPane, which appears as needed. I don't know if there is any demand for this, so I'm just running it up the flagpole. WARNING: The last thing you need is for a bug in ScrollPane. I don't know of any in this code, but better safe then sorry. So consider this a beta. Please tinker around with your applications to make sure everything is working ok before saving your image. Tested on a fresh 3.4 image w/ updates up to #5138. "!

[BUG] can't find EOCD position when loading SqueakSource from SqueakMap
by bernhard＠pieber.com 29 Feb '04

29 Feb '04

Thanks for setting up the SqueakSource repository! I find it really cool and wanted to try to set up my own server for playing around. However, I did not come far. I tried to load SqueakSource 76 from SqueakMap and I got the following error: 'Error occurred during install: can''t find EOCD position' I tried it with Squeak3.7alpha-5707 and Squeak3.6 and got the same error. I just wanted to let you know about that. Is SqueakSource its own WebDAV server or do I need my own? Is there documentation I should read before I bother you on this list? - Bernhard
