Squeak listening to specific IP Addresses?
by Peter William Lount 03 Apr '04

03 Apr '04

Hi, Is it possible to configure Squeak to listen to specific IP Addresses and Ports, i.e. 1.2.3.4:8000, on a machine that supports multiple ip addresses? If so how? If not, how can we add this feature? A further example is running a Comanche squeak server on 1.2.3.4:80 and on 5.6.7.8:80. Two basic configurations interest me. 1. Restrict a squeak image to a specific ip address (or more than one specific address) from the set of addresses that are being homed on the server. 2. Enable squeak to listen to specific ipa:port pairs from the set of addresses that are being homed on the server. All the best, Peter William Lount, Smalltalk.org Senior Editor peter(a)smalltalk.org peter(a)activeinfo.ca

[BUG] Hidden Information/HyperText, alt-6 in GeeMail
by David Faught 26 Mar '04

26 Mar '04

In the TextPlus area of a GeeMail morph, the alt-6 menu comes up, but does not work properly. Specifically, entering: A Link<http://www.whatever.com> selecting all that text, doing alt-6 (on Windows), and selecting "be a Web URL Link" from the menu gives the following result: A Link<http://www.whatever.com>[No hidden info] and no link is inserted. This is in a 3.5 image. __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com

Hi all for the demo of Squeak I'm preparing I would like to show the VM can be interprted. I did the following steps with alex and we are stuck: - took a 3.6 image - created a mvc project - saved the image named mvc36 - took a 3.6 image - executed (InterpreterSimulator new openOn: 'mvc36.image') test We did the same with the latest 3.7alpha 5623 - we load VMmaker from SqueakMap 3.6g2 and in both cases we got the following DNU What did we forget?

[BUG] FileContentsBrowser doesn't filein 'all' protocol
by Tim Rowledge 10 Mar '04

10 Mar '04

Just noticed this; in a filecontents browser if you pick a class youcan filein all the stuff for that class. If you pick a protocol you can filein all the methods in that protocol. However, if you pick 'all' protocol, you don't get to filein all the methods visible.

[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

[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. "!

[ENH][Refactor] PLMCleanUpStart
by Daniel Vainsencher 27 Feb '04

27 Feb '04

"Change Set: PLMCleanUpStart Date: 9 August 2003 Author: Daniel Vainsencher This changeset adds comments for all PLM subclasses. Also removes the assumption of uniform height in PluggableListMorph (not yet in subclasses), and refactors the morph generation. Might slow list update down a bit. Factors out the StringMorph creation and initialization logic to simplify the methods and reduce duplication. The goal is to introduce the ability to accept items other than String/Text/MethodReference, and display them as morphs other than StringMorphs. Patches/advice about how to handle PLM variants welcome."!
