RE: displaying forms rapidly without skipping frames.
by Mike Shields 02 May '02

02 May '02

Is a step method the wrong way to do this? Not a Squeak expert, but the step thing seems to get sent pretty regularly. -Mike -----Original Message----- From: Yisrael Lowenstein [mailto:gte356h@prism.gatech.edu] Sent: Thursday, May 02, 2002 2:21 PM To: squeak-dev(a)lists.squeakfoundation.org Subject: Re: displaying forms rapidly without skipping frames. > 30 fps can bring Squeak to it's knees if the images are big. The images are small, and I don't need to refresh the whole screen..just that part of it... How does the mpeg player do it? Might the problem be that the Delay is keeping it from being refreshed? is there a different way to delay or to just make the delay delay in the block, and not the whole system? does fork do this?

Re: SUnit Woes: Object>>testing
by danielv＠netvision.net.il 02 May '02

"self testing" is used in the RB as a form of notation saying that the code is not quite complete/stable. It does nothing. I don't recall this causing trouble when I was working on the port, maybe SUnit changed. You can just remove the method and all it's calls if so.

[RFI] Possible enhancements to work on at the Squeak-End
by Chris Muller 02 May '02

02 May '02

My #1 request is something that I've wanted in Squeak since being introduced to it: THE ABILITY TO HAVE WHITE TEXT ON DARK BROWSER WINDOWS. Squeak's bright display is a constant assault on my eyes that, sadly, cannot be inverted without some serious code hacking. I made a cut at it last January (search Yahoo for "sensible contrast") and even posted my code, but it turned out to be too much for my limited Morphic background. My strategy was to change the various Morphic widgets that painted text, to change the hard-coded black to white if the luminance was below 50%. The problem, if I remember correctly, was I could never find teh correct color, or I was always getting Color transaparent.. __________________________________________________ Do You Yahoo!? Yahoo!

Also take a look at SUnit class>>shouldInheritSelectors I subclass TestCase to override this default to false. Another, probably better solution looks like Behavior>>sunitAllSelectors should exclude methods from Object. - Chris __________________________________________________ Do You Yahoo!? Yahoo!

[BUG] MailMessage/MIMEDocument parsing doesn't work beyond the first level.
by Ken Causey 02 May '02

02 May '02

I've been trying to parse email messages with more than the simplest of structures and can't seem to get anywhere. VM: Linux 3.2-4743 #1 [oss audio, xshm] Image: 3.2gamma-4843 Consider an example: Take an email with an attachment, and forward it as an attachment. Diagram: a Email b Body c Forwarded Email d Body of Forwarded Email e Attachment The problem is that no matter what I do, I can't get to the attachment, part e. Or for that matter the body of the forwared email, part d. I can see 2 ways of going about this: 1. The body of a MailMessage instantiated from the original email message (MailMessage class>>from:) returns a MIMEDocument whose parts message returns an Array with 2 elements. The first element is a MailMessage whose body is a MIMEDocuement containing the text labelled as part b above. The second element is also a MailMessage whose body is a MIMEDocument includes all of c-e. However, this MIMEDocument's parts message returns an empty array. I'm stopped at node c. 2. Again, instantiate a MailMessage using MailMessage class>>from: from the original email, use MailMessage>>makeMultipart and MailMessage>>parts returns an OrderedCollection instance with 2 elements. The first element is a MailMessage, again MailMessage>>makeMultiPart and MailMessage>>parts on it returns an Array with only one element, it being a MailMessage whose text is part b. If you run makeMultipart and parts on this MailMessage, you keep getting one element Arrays with the same text. I guess we can consider this a recursion limit criterion. Now, take the second element of the two element Array returned by the first level of makeMultipart/parts. This is a MailMessage whose text contains all of c-e. Recurse with makeMultipart/parts again and we get an Array with ONLY one element, a matching MailMessage. Continued recursion never visits d or e. I would really appreciate it if someone can point out my mistake/misunderstanding here. Otherwise I have to consider the MIME system to be less than useful. Ken Causey

[ENH] gentle encouragement to add a class comment (was [RFI] Possible enhancements to work on at the Squeak-End)
by Mike Rutenberg 02 May '02

02 May '02

Doug, I originally did this for 2.8. I've quickly reworked it for the current system. It annotates the class definition (as displayed in the browser) with a short comment that indicates whether a class comment still needs to be defined. This works with both normal and alternative syntax. It goes away as soon as a class comment is defined. I find it looks very busy if I include the whole class comment in the class definition pane, though it would be relatively straight foward to do if really desired (have to be careful about quotes). Also, I think the "Note:" will stand out more starkly if it is only there when there is no comment, rather than slightly different text if there is a comment or not. Mike

[RFI] Possible enhancements to work on at the Squeak-End
by Doug Way 02 May '02

02 May '02

Here are some RFI's (Requests For Implementation) that I've been jotting down over the last several months. These are basically some ideas for enhancements to Squeak, some of which should be small enough for folks to implement at the Squeak-End, which I'll be attending. (not everyone likes to work on bug-fixes, sometimes new features are more fun) Since this is mostly brainstorming, comments are definitely welcome. I've listed the ones that I think are easier first. * Display Class Comment in Definition Pane Display a class' comment below the class definition in the browser (in double quotes), so that it's immediately noticeable when browsing through classes, and also immediately apparent when it's missing. If there is no comment, use the string "This class has not yet been commented." instead. (VisualWorks now does this.) For simplicity's sake, editing the comment could still be handled by switching to the comment pane (via the "?" button). * "Decompress to file" Should Refresh The "decompress to file" menu item in the FileList (for .gz files) should refresh the file list afterward, and probably select the decompressed file, too. * Store Output in the Transcript Even If Not Open? I haven't really looked into whether this is easily doable, but it will be very cool if it were possible to store output directed to the Transcript, even if a transcript window wasn't opened yet. Then, when you opened the transcript window, the output would already be in the window. It often happens that I forget to have a transcript window open when I need to look at the output from some operation, and this would solve that problem. * Class-side Changes in FileContentsBrowser The FileContentsBrowser should show class-side changes with a separate "ClassNameXXX class" class-side entry in the class pane (in addition to a possible "ClassName" instance-side entry). This would be just like how the change sorter displays class changes, and would prevent accidentally overlooking class-side changes. We could also get rid of the instance/?/class buttons then. (Perhaps class comment changes could be appended to the class definition area.) * TextEntryMorph Create a TextEntryMorph, which is a text morph restricted to a single line, which does not change its size as text is typed in, ignores CRs, and also horizontally (not vertically) scrolls itself as text (of unlimited length) is typed or highlighted past the edge. Very useful for specific applications. * Class Definition Timestamps Class definitions should be stored with a version timestamp, just like methods are. They're stored in the .changes file anyway, right? Then you could see instance variable/etc changes show up by browsing "versions" for definitions, with diffs! Seems like this shouldn't be impossible. ENVY never even supported this, for reasons I've never understood. (This one's more of a brainstorm, probably not doable during the SqueakEnd.) * Command Completion Dependent on Preceding Expression It would be really cool to have command completion (alt-q) work in workspaces/inspectors, such that the preceding expression is parsed and evaluated first so that the outputted "type" of the expression is known, which can then restrict the messages listed to the ones that object understands. On second thought, this may not be feasible, since you probably don't want to evaluate expressions which have side effects, or take a long time to execute, ah well. * Have MethodFinder ignore methods which only return self. (it could just return self for those methods, without actually executing them) This would greatly reduce the number of hardcoded methods-to-avoid. (is there a way to quickly detect if a CompiledMethod always returns self?) Admittedly, this one is just a random brainstorm. - Doug Way dway(a)riskmetrics.com

Which book
by Jason Dufair 02 May '02

02 May '02

I've seen mention of several Squeak books here on the list and on c.l.s., but I want to know which one(s) would be a good fit for me. I looked at reviews on Amazon.com and it wasn't obvious, based on my skills and current needs. I am currently employed as a Smalltalk developer and have a decent grasp of Smalltalk, specifically the VisualWorks flavor. I've also done a lot of other programming, including Perl, PL/SQL, VB, C/C++, and others. I want to build a multimedia PC for my home and have a Squeak-based frontend to control it. The only display will be my television and the only input will be a remote control, presumably with an arrow pad (left, right, up, down) and not a mouse or trackball. I want it to be the following: an MP3 jukebox, an answering machine, a tv tuner and PVR, a video (i.e. MPEG, DiVX, WMA) library, and an app launcher for games. I'll be making this freely available, by the way, and would be glad to have help if anyone is interested. Can anyone recommend which Squeak book to buy? Projects that may have attempted this type of thing? Caveats about my dream system? Thanks! -- Jason Dufair - jase(a)dufair.org http://www.dufair.org/ "The oldest one captains the bleak white ship of bone with palsied hands The one of middle years wears a hope like chains The youngest one cries tears of scarlet, and adjusts her latest smile" -- ToasterLeavings
