Re: Messaging vs. Methoding

You can find his proposal at > http://www.smalltalksystems.com/publications/varargs.pdf A year or so ago I thought about what adding optional keyword messages to Smalltalk would be like and how it would work... Brian's proposal is pretty much in line with what I was thinking. I never thought of repeated keyword messages, though. Neat! (No more arbritary limit of 4 "with:"s when creating a new OrderedCollection. Use 17 "with:"s like you've always dreamed of! :-)) The only thing that I would add is that it would be good to have some sort of notation in the method list pane of the browser to indicate optional keywords... my original thought was to use parentheses, such as: reMatch:(opt:)(from:)(to:) .... to use agree@carltonfields' example. This makes it clear when browsing through code that the last three keywords were optional. (Only the method list pane would need this notation, I think... the method definition text would follow a format such as the one mentioned in the proposal.)

This wouldn't be a problem... at least based on the proposal above, the compiler would generate all possible messages (8 in this case): reMatch: reMatch:opt: reMatch:from: reMatch:to: reMatch:opt:from: reMatch:opt:to: reMatch:from:to: reMatch:opt:from:to: So all of these would be valid. If the message reMatch:opt: already existed for this object, the compiler would detect that and prevent you from accepting the method. Of course, the general argument against adding optional keywords is that probably a relatively small percentage of Smalltalk methods would really need to take advantage of having several optional keywords, so it might not be worth its weight. Still, it's an interesting idea that would be cool to prototype. - Doug Way EAI/Transom Technogies, Ann Arbor, MI dway(a)eai.com, dway(a)mat.net http://www.transom.com Smalltalk: Guaranteed Y2T Compliant

Re: [VM] NCM performance report
by johnm＠wdi.disney.com 25 Mar '99

25 Mar '99

Helge: Thanks for measuring the performance of Tim's NCM VM. The send speed is nicely improved. Tim: to what do you attribute this speed boost? I may have misunderstood the NCM changes, but I thought they mostly allow flexibility in how one encodes source code pointers, while eliminating some special-case handling for compiled method formats. Do all the speedups arise from those simplifications, or did you slip in some other optimizations? Nice work! -- John Helge Horch <Helge.Horch(a)munich.netsurf.de> wrote: > I've been running Tim Rowledge's NCM VM and image (see > <http://sumeru.stanford.edu/tim>) on win32 successfully for a while now. > I'd like to offer a short performance report, because I think (and feel) > that I get appreciable results. >...

Re: Multilingual Squeak

To try and tie together two different threads, the multilingual guys want to have many identifiers for a single object, and the name-space guys want to have single identifier for many objects. Loosely squeaking, er, speaking, Klein.(Mike | Michael) mklein(a)alumni.caltech.edu

modelWakeUp not sent after Morphic snapshot
by mdr＠scn.org 24 Mar '99

24 Mar '99

My Celeste model gets sent the message modelWakeUp in both Morphic and MVC when it has been behind another window and you click on it to bring it to the front (That seems to work fine!). When Celeste has been at the front, and then you snapshot, and the snapshot returns (or restarts) the window is still at the front. In MVC the modelWakeUp message is sent to the model, but this does not appear to be done in Morphic. I have to go home to sleep, but wanted to mention this so that some Morphic engineer (who know where to look) can figure out an easy fix for it. Mike

building things for both Morphic and MVC
by mdr＠scn.org 24 Mar '99

24 Mar '99

I made some low-level changes to Celeste to ensure it is more robust across snapshots. Those (somewhat window system dependent) changes work fine in MVC, and I did not even think to test them in Morphic (since I mostly live in MVC land). We are living through a slow transition from MVC to Morphic, and I am wondering a bit what the parameters are. Is it worth fixing the remaining second order bugs in MVC (such as the FormViewer doing weird scaling when the picture is too large to fit normally on the display) when they work properly in Morphic? When I do new mini-functionality, such as an address book for Celeste, how important is it that it runs in both MVC and Morphic, rather than just Morphic? Just curious what people's thoughts are...

Morphic Trashcan & Halo Remove (and some misc. ???)
by Norton, Chris 24 Mar '99

24 Mar '99

Hi Folks. I've been playing around with the latest changes to Squeak 2.3+ (pretty cool BTW) and I discovered that if I accidentally (I'm quite clumsy) click on the white halo circle (remove) for a morphic widget it gets removed (as the balloon help suggests it should). Question: Why doesn't the removed widget go into the trash can I placed on my tableau? Should it? I find that it is entirely too easy to accidentally remove a widget, esp. if it's halo is small (I've had to start over a few times because of a stray mouse click). Just a thought. ---==> Chris PS> Can anybody explain to me what the "transform" halo is? Some morphic widgets apparently have them, but others don't. When I try to adjust the size of the transform halo, nothing seems to happen. PPS> I have had some fundamental problems understanding Morphic. Does anybody have a recently updated web page that describes (in a more or less procedural fashion) how to wire up a simple application (with more than one widget tied together) for Morphic that I can look over? Thanks!!!

A Simple Components Example
by Mark Guzdial 24 Mar '99

24 Mar '99

With thanks from Andrew and Helge, I got an example Morphic Components project to work. The error that I was getting about "Attempt to execute an already executing block" was because I was starting with a fresh 2.3 image. It was trying to get my initials! Once my initials were input, the error went away. So, here's the simplest example I could come up: - Create a ComponentLayout morph (in Morphic, New Morph, Components, ComponentLayout). - Create a PrintComponent, a TextComponent, and a FunctionComponent, and drag all three into the ComponentLayout. - Not necessary but looks good: Put the TextComponent in upper left, FunctionComponent in center, and PrintComponent in the lower right. - For ease of pin manipulation, set the scrollbars on all three components to inboard (available from the Red Halo menu). - Shift-click on the TextComponent pin, and drag the yellow handle to the input (leftside) pin on the function component. - Shift-click on the output pin (bottom) of the FunctionComponent and drag to the PrintComponent input. - Now, type a 12 (or any number) in the TextComponent and accept (Enter or Command-S works on Macs). - In the FunctionComponent type "a asString asNumber factorial" then accept. If all goes well, the result of 12 factorial should appear in the PrintComponent piece. One of the problems I was having is that the output of a TextComponent is a Text -- not a string, not a number. That's why the conversions in there.
