[BUG][FIX] PostscriptCharacterScanner DNU #setAlignment:
by Richard Staehli 04 Jun '04

04 Jun '04

This bug has been around a while, but I just discovered the workaround someone posted on the swiki. The problem can be reproduced simply: - in 3.6 image, open a new StackMorph - add a TextMorph to the first page - set text alignment to centered - from the Stack's red "menu" halo button, select "copy & print" -> "print Postscript to file" and accept defaults. - a walkback appears: "PostscriptCharacterScanner doesNotUnderstand: #setAlignment:?" This problem can be fixed by the suggestion posted on the swiki's "Postscript support" page. The fix is to modify the class 'PostscriptCharacterScanner' to be a subclass of 'CharacterScanner' and remove from the former the instance variable 'font'. I do not know if this fix causes other problems. Here is the change to PostscriptCharacterScanner: CharacterScanner subclass: #PostscriptCharacterScanner instanceVariableNames: 'canvas paragraph bounds curPos foregroundColor emphasis ' classVariableNames: '' poolDictionaries: '' category: 'Morphic-Postscript Canvases'

[BUG][FIX]MouseMoveEvtStartPos-ar
by Eddie Cottongim 04 Jun '04

04 Jun '04

>From Preamble: "Change Set: MouseMoveEvtStartPos-ar Date: 18 August 2003 Author: Eddie Cottongim Fixes a bug where MouseMoveEvents would not report their startPosition correctly. Change by Andreas Raab." To observe this bug, execute "HandMorph showEvents: true" and observe the starting point for mouse moves. Its usually wrong - most of the time, start point = end point. It makes much more sense after the patch. The change makes sense to me. startPosition is now set to the hand's current position. Since the hand hasn't yet been moved in response to the event being formed, it makes sense that the hand's current position will the the starting point for the next mouse move event. Someone should see if this helps/hurts Genie - Genie uses the start position for mouse moves. I'm suprised it would work at all given the old, broken behavior. Thanks, Eddie

[BUGFIX] Point>>reciprocal
by Trygve Reenskaug 03 Jun '04

03 Jun '04

I have a simple Morph structure: SlideRM(BorderedMorph) TransformMorphRM(TransformMorph) SlideInnerRM(PasteUpMorph) The Transform scale was aPoint. I got error when computing the inverse transform because Point does not understand reciprocal, see attached bug report. A simple fix could be a new method to Point: reciprocal " Answer a Point with coordinates that are the reciprocals of mine. " " Method was missing from release. " " 20040301 20:50:35 TRee(Squeak3.6-5429-tree07.38) " ^ x reciprocal @ y reciprocal. --Trygve -- Trygve Reenskaug mailto: trygver(a)ifi.uio.no Morgedalsvn. 5A http://heim.ifi.uio.no/~trygver N-0378 Oslo Tel: (+47) 22 49 57 27 Norway

[ENH] new String modifier: String>>asPlural
by Norton, Chris 24 May '04

24 May '04

Hi Folks. Here's the preamble from my changeset: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "OK. You could say that this is a silly crusade, but I like my Squeak messages to be in proper English (at least when the language you're using is English). I was messing around with the HangMan file-in and I got a walkback that had the following title: 'Error: HangManPhrases classs are not indexable'. I just couldn't stand the extra 's' on 'class', so I created a nifty new String method called asPlural and I modified the sender of the odd string to use the new String modifier. Take it or leave it, but I think this makes auto-generated text just a little easier to read." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I hope you find this new String modifier useful too. Cheers! ---==> Chris <<PluralStrings-ccn.cs>>

[BUG][FIX] Scrolling in MVC (small)
by Boris Gaertner 22 May '04

22 May '04

Hello, earlier this day I posted a mail with a list of bugs that I think should be fixed before we close 3.7. For one of these bugs, no fix has been proposed so far. I am therefore really happy to offer a problem analysis and a fix for the bug that is registered under BFAV archive ID 14350, posted at Nov 26, 2003. For quite a time, I was only able to hack around a problem that I did not understand, but now I think I have found was goes wrong. Here is the bug description again: ( from the cited bug report) >In an MVC project, open a file list and select a text file. >Place the cursor into the text view (at the beginning of the text) >and scroll down with the down arrow. >When you reach the end of the text, you will get a notifier >with the message as soon as you release the 'arrow down' key: >MessageNotUnderstood: UndefinedObject>>first >This comes from >ParagraphEditor>>sameColumn:newLine:forward:, And here is an analysis of the bug: In method ParagraphEditor>>sameColumn: start newLine: lineBlock forward: isForward we read: targetLineNumber _ ((lineBlock value: currentLineNumber) max: 1) min: lines size. where lines is a temporary variable of the method. Under some circumstances, the method fetches the lines from the paragraph that is edited. (The paragraph is an instance of Paragraph in MVC and an instance of NewParagraph in Morphic) Under different circumstances, sameColumn:lineBlock:forward: computes an array of lines (this is done by ParagraphEditor>>lines). In NewParagraph, 'lines' is used under an exact fit policy: For a paragraph that is composed to be displayed in n lines, the size of the array is n . In a Paragraph, 'lines' is an array of TextLineIntervals. In Paragraph, the array 'lines' is used under a "keep additional space" policy and the correct number of lines is stored in instance variable 'lastLine' and can be accessed with the method Paragraph>>numberOfLines When sameColumn:lineBlock:forward: computes an array of lines, it can use 'lines size' to obtain the number of lines, but when it uses the lines from the paragraph, it has to use 'paragraph numberOfLines' to obtain the number of lines. Solution: To handle both cases, I use an additional instance variable to keep the number of lines. I would be glad to see this fix in the final 3.7 (if that is still possible), so can some fellow with an interest in MVC please review my proposal? Thank you a lot! Boris

3.7 Full: Developers or Media users?
by Diego Gomez Deck 21 May '04

21 May '04

Hi folks... I'm working on assembling the full image for 3.7. There are some packages that make sense for developers but for media-users. (VMMaker, Refactoring Browser, etc). The goal in Small-Land is to cover media-users. So the question: The Full 3.7 has to cover users AND developers? I vote to cover only user assuming the developers can assemble they own images. The other option is to assemble more than one Full-Image (Media, Developers, etc) but in this case we need more soldiers. Thoughts? Diego

I've pushed a Mac VM 3.7.0b2 for testing to http://homepage.mac.com/johnmci/ Squeak 3.7.0Beta2.app.sit It contains: a) You can alter the application's Info.plist by setting the SqueakEncodingType using the ICANA readable names macintosh - >macRoman UTF-8 -> UTF-8 b) Support for sqSocketListenOnPortBacklogSizeInterface, which allows you to specify the interface to use for the listen should work both for os-x and os-9. c) Usage of VMMaker3-7a2. d) Special change sets: make primitive point x/y internal, and slightly faster activate. -- ======================================================================== === John M.
