-- Folks - We are now beginning to issue some of the fixes and enhancements from this list. Thanks to you all, and especially to your trusty Fixes and Enhancements Committee (especially Stefan, Doug and Bob). - Dan ---------------------- 4304startAllEtc-sw -- Scott Wallace -- 4 September 2001 Adds etoy scripting commands startAll:, pauseAll: and stopAll:, which serve to change the status of a given script in all sibling instances of an object by a single gesture." 4305DumbMacHack-sma -- Stefan Matthias Aust -- 11 November 2000 Make sure that the change set's file name is no longer than 31" 4306BrowserFixes-jlb -- Jim Benson -- 14 August 2001 Fixes a DNU if you left click into an empty method category pane." 4307insertPageFix-mdr -- Mike Rutenberg -- 14 August 2001 Minor fix for a boolean expression bracketing problem in BookMorph (methodsFor: 'insert and delete') insertPage: aPage pageSize: aPageSize atIndex: anIndex Was: (pages isEmpty | anIndex == nil) Now: (pages isEmpty | anIndex isNil)" 4308SkipLists-lc -- Leandro Caniglia -- 18 June 2001 Based on Skip Lists: A Probabilistic Alternative to Balanced Trees by William Pugh" 4309BlueMPEGFileDialog-kfr -- Karl Ramberg -- 11 August 2001 Better file dialog for MPEGMoviePlayerMorph (the blue one)" 4310SqueakListChangeFix-nk -- Ned Konz -- 8 August 2001 This changes the hard-coded name of the Squeak list in the mail out bug report or change set operations to squeak-dev(a)lists.squeakfoundation.org 4311CelesteFirstOpenFix-nk -- Ned Konz -- 8 August 2001 In a fresh image, Celeste current will open a new Celeste window, but will return Celeste (the class), rather than the new Celeste. This can be seen, for instance, by emailing a change set to the list from a fresh image. This change set fixes this problem, which was introduced in the 4170dbLessCeleste-ls change set. 4312StarMorphShfClickFix-nk -- Ned Konz -- 8 August 2001 If you create a StarMorph and shift-click on it a couple of times, you'll get a walkback because PolygonMorph doesn't know about StarMorph's editing of its vertices. This fixes the problem. 4313BetterDebugger3-hmm -- Hans-Martin Mosner <hmm(a)heeg.de> -- 29 July 2001 Some more additions to the debugger: 1. Support for stepping into blocks (thanks to Henrik Gedenryd) 2. A NonBooleanReceiver exception 3. Balloon help for the debugger buttons 4. A problem with handling exceptions in the debugger was fixed (when you stepped into the exception handling code, and then did a step which executed the #signal method, it would open a separate notifier) Handling of #mustBeBoolean in code being debugged is still a bit rough... 4314NumbersAsWords-RAAdi -- Bob Arning, Dan Ingalls -- 24 August 2001 Bob: Defines #asWords for Integers. For example, SmallInteger maxVal asWords ==> 'one billion, seventy-three million, seven hundred forty-one thousand, eight hundred twenty-three' Dan: Also includes a couple of fixes so that Speaker does a reasonable job of pronouncing these numbers. 4315Fix4305 -- Andreas Raab -- 4 September 2001 Fixes a bug introduces in 4305 no longer adding the change set version numbers."

Re: [ENH]Refactoring Browser cosmetic tweaks (for 3.1a update #4303)

Does anyone know why I can't see Steve's attachments in Celeste? Does any of the mime-parsing-fixes sent lately to the list handle this sort of attachment? If so, I'll be happy to test it... BTW, I assume other people see them in other browsers, right? Thanks. BTW, Stephan, maybe you'd consider publishing changes using the mail-out-changeset menu in the change set browser? I know I can read those... "Stephan B.

Gaining the benefits of hardware acceleration
by Mark Guzdial 05 Sep '01

05 Sep '01

I was playing with Wonderland last night with my son (making a White Rabbit do circles in a castle). We turned on hardware acceleration. It took effect -- the grass changed color. But our White Rabbit suddenly started moving SLOWER. Turning off hardware acceleration sped him up again. What did we do wrong? Do I need to turn on hardware acceleration BEFORE making my actors?

[GOODIE] SPSMethodBrowser: constrain scope of searches, new widgets.
by Steve Swerling 05 Sep '01

05 Sep '01

Hi, Get the SPSMethodBrowser here: http://users.bestweb.net/~swerling/squeak/spsMethodBrowser.1.cs.gz The SPSMethodBrowser adds a search pane to the standard message browser (the one that you see when you browse for senders, implementors, etc). In the search pane you can do the usual searches, but you can constrain where to look. For instance, you can browse for all source code containing the string ""#whoHandlesThis"" within the ""Morphic"" package. You can restrict the search to be within a class, a class branch, a package, or the whole system. Also included are implementations of a ComboBox and a DropDownList that some may find useful. ===== From the changeset preamble:======= The SPSMethodBrowser adds a search pane to the standard message browser (the one that you see when you browse for senders, implementors, etc). In the search pane you can do the usual searches, but you can constrain where to look. For instance, you can browse for all source code containing the string ""#whoHandlesThis"" within the ""Morphic"" package. You can restrict the search to be within: a class, a class branch (a ""local"" search), a package, all of smalltalk. You can do search for: senders implementors source containing a string references to globals (including classes), references to Class variables selectors with a substring Just like in the method finder. enter in part of the method name, and a list of methods that contain the search string in their name are searched for). by example Also adapted from the method finder. Search for a method based on the arguments it takes and its output."

Re: Modularity vs monolithic images

Francisco Garau (a SUGAR guy) demo'ed his Concrete Type Inference at ESUG. I don't if it's applicable, but he should be able to answer that (not very soon, he was going on vacation). I think it should be - he was doing an algorithm along the lines of one of the approaches that was being looked at for Self (I think it lost, type feedback won. Not sure, though). > Someone was doing type inference for Squeak. Whatever happened to that? >

Re: [Modules] a summary of joseph's work
by danielv＠netvision.net.il 05 Sep '01

Hi Paul. That's not exactly my point - I don't think there's a technical problem here with ModSqueak. we need to face these questions: * Do people *want* to work in modules all the time? They aren't now. (SqC, for example) * How do we handle mixed situations (either the transition period, or a stable state)? I'm saying this because it seems we might enter this transition time any time now, I think we should have an idea on how. PS, Paul, if this is veering outside the modsqueak(a)bluefish.se appropriate usage, don't include it in the reply. I guess you know the house rules better than I... > > * and not see all the new cool eToy stuff SqC is > > working on? > > * and anyway, if Lex and Daniel do start maintaining > > Celeste in a module > > outside the SqC image, how does this mix in with the > > updates review > > team? > > * how will I get the bug fixes and tweaks for > > Celeste, if that's not in > > the update stream? > -- I think the end goal (one of them) should be for > ModSqueak to provide its facilities in a robust > enough, and distributed enough, fashion for both SqC > and the rest of us to work in modules.

[GOODIE]New Version of SPSBrowser
by Steve Swerling 05 Sep '01

05 Sep '01

This version of SPSBrowser adds some performance enhancements to further reduce CPU usage. Also included are some miscellaneous changes. The changeset is located at: http://users.bestweb.net/~swerling/squeak/spsBrowser.2.cs.gz === From the preamble: ==== The SPSBrowser is similar to the PackagePaneBrowser but enhances it in 2 ways. First, it adds a class hierarchy view using a widget based on the SimpleHierarchicalListMorph, which you may be familiar with from the object explorer. It sounds cramped, but it works out quite nicely. Second, the performance is improved over the PackagePaneBrowser by caching information about the SystemOrganization. This eliminates what some may have noticed is a signifigant lag when selecting a method in the PackagePaneBrowser (this is only noticable when one of the top level packages is selected). It also reduces the toll that the PackagePaneBrowser takes on the CPU (on my machine it is about 15% of the processor capacity for each open package browser, the SPSBrowser is less than 1%). ============================

Re: Reminder: Please compress all changesets posted to the list
by danielv＠netvision.net.il 05 Sep '01

05 Sep '01

Just reminding everyone that this is trivial to do - just use the "mail out to list" feature of the changeset browser, it reminds you to use a [FIX]/[ENH] header, and does the compression for you. </shameless plug> Just pick up one of the numerous fixes posted that modify the To: field to be set correctly. Or do that manually. Or search for the wrong address string and fix it... Please, Doug, put one of those mods on the next updates so people can just use that. This one by Ned is perfect, updates the address for the changeset mailout and bug mailout. (searchable on the SQFIXes) [FIX] SqueakListChangeFix-nk (8 August 2001) While you're at it, there is also a fix to the new superflous headers this mail server adds. This one works great, and is only one method, so I'm willing to vouch for it - [GOODIE] Re: Mailing list headers (10 July 2001) * Mike Rutenberg (9 July 2001) Doug Way <dway(a)riskmetrics.com> wrote: > > This is just a reminder to everyone posting [FIX]es and [ENH]anhcements > to the list: > > *Please* compress your changesets as .gz files before attaching them to > your message. > > - Doug Way > speaking as a Squeak Fixes Review Group guy :)
