[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>>

SMInstaller (was re: [ANN] Seaside 2.02)
by danielv＠netvision.net.il 08 Nov '02

08 Nov '02

That's the main problem I'd like to solve by having install be one registered service of many that can handle packages. The design would allow the user to choose the tool he wants, and have many installers active for the same package.

Re: [ANN] SqueakMap RC2 and SM Loader 0.96 out
by danielv＠netvision.net.il 31 Oct '02

31 Oct '02

Did you get a dump or something? I haven't gotten around to trying out VI4, so I haven't tested the RB on it. It uses blocks, including calling fixTemps on them, since it sometimes assumes the blocks are closures. Might cause a problem that they suddenly are? When did the hand occur? during use, or during filein? Do you have a recipe that reproduces this? if you do, I'll load VI4 and check it out.

Annoyance: Hierarchical Browser
by Ross Boylan 02 Apr '02

02 Apr '02

Most of the time when I open a hierarchical class browser the focal class is invisible, since it is below the very tiny scroll area that is shown. This seems a bit odd, since that class is highlighted (when scrolled into view, and it is controlling what you see in the other windows anyway). I see this both on MS Windows and Linux, though I wonder if it's a font thing and it looks OK on, e.g., a Mac.

[M206] how to do M206 diagrams in Squeak
by John Hinsley 11 Jan '02

11 Jan '02

Just posted for fellow M206 sufferers a short HOWTO do M206 diagrams in Squeak. "It's CRC, Jim, but not as we know it". It's at http://www.penguin-home.telinco.co.uk/M206_diagrams Does anyone happen to have the URL for Mark and Lex's CRCCardMorph to hand?

RBSqueak - what's next
by danielv＠netvision.net.il 04 Dec '01

04 Dec '01

First of all, I've seen no bug reports. Is it perfect? is it unusable? Anyway - I've been looking at the RBPort as it stands, thinking about what's needed to move it to the next state - from Beta code to something that could be folded into the base image. As an aside - Eventually putting the RB in the base image is not my call, and it's not fair to ask people to make that call before I've made the changes that are neccesary. OTOH, if they (changes review team/SqC) should pitch in with advice/guidelines, I'd be inclined to take them into consideration... Back to track. First, what we have now - The port currently has four files - * my trivial, insignificant ClassBuilder fix(?) * The RBModel changeset (including mostly new classes, and some small and not so small changes to base classes) * The RBUI changeset (including lots of empty VW classes that have either been replaced with the morphic equivalents or are simply not being used now) * and the CS3 work changeset, addin and modifying to the classes defined in the above. There are already some contributions sent on the list and to me privately that are mostly further modification of the package's classes. Stephen B. Wessels aesthetic updates are among those, but include a dependence on the variables pane (which, btw, I like, and could itself make better use of the RB...). These make it more important to clean up this package, in order to stave off chaos... As I see it, the main requirements to being able to add the RB to the main and SWT images (or for the package to stay live if it isn't) are- * Changes to base classes are minimised and separated out to changesets. Preferably, for the ones that are positive to be accepted into the image, separate each change to make it easier for the review team to decide on each. * Classes that are not being used should be discarded. This raises questions about the functionality they represent, but that's a worry for later. * New classes should be packaged as modules, that is, no class/method additions/removals, just definitions of code that's being used. I'm going through this sorting process now. What I'm discarding (with class comments/my comments)- * Navigator (plus subclasses and collaborators) Navigator is an abstract class that defines the interface that displays the classes/methods of an BrowserEnvironment. Its subclasses define what actions can be taken for the different selections. * CodeTool (plus subclasses and collaborators) CodeTool is an abstact class represents the tools that can appear when a user has selected an item (e.g., a class) using the navigator. These tools are dynamically switched depending on current selection. * OMT-Diagram (a whole category) A graphical way of viewing a class in a hierarchy diagram. CodeTool and its subclasses factor out the multiple uses and meanings of the bottom pane of the browser, splitting the functionality into separate classes. Would make it easier, for example, to add a new tool for viewing the new XML UI Spec in a hierarchy widget. It could be used to factor out showing the code in alternative ways, like SyntaxMorphs, and so forth. So this is a pretty useful concept to have, eventually, in all our browsers. Navigator allows one to isolate the state of the Browser (what are we browsing, what's selected). It's subclasses give the shape of the browser - some look at one class, or one protocol, and so forth. The different types of Environments know what navigator should be used to look at them. Right now our poor Browser and RefactoringBrowser take on all these responsibilities, making them, well, slightly obese? Another recurring theme in doing the glue code for the RB UI to call the RB model, was that this requires some additional responsibilities which the UI might not be best suited to carry. Right now the UI has to know that after doing an Extract Method,it should refresh the code pane and the messages list, and refocus on the method with the same name as before (not the same index..). Assuming someday we'll want to integrate the RB into alternative browsers like Whisker, there's no real reason why that should hard coded in yet another UI... So that's another refactoring that needs doing at some point. I'd like your thoughts on how the RB work should proceed and specifically about it's link with other Browsers... Daniel

J3 executable for win2k
by Heiko Schaefer 12 Oct '01

12 Oct '01

Dear all, I would like to try out the J3 JIT compiler. Under 'Maximum Squeak' on the swiki I found the source, but was unable to build it under Win2k. Where could I find executables for win2k? Otherwise to you have any hints on how to build a J3 VM under win2k (I use cygwin, which might help?) Thanks a lot for your help, Heiko

Font Support
by David N. Smith (IBM) 09 Oct '01

09 Oct '01

All: The single most troubling problem in Squeak is the lack of real font support. I've just finished a large, packaged program and had to make do with NewYork, and images of large characters in a font cut from Illustrator and pasted into Graphic Converter, then twiddled, and then saved as GIFs, in three large sizes, for about 30 characters each, then read into the program and then laid out by code I wrote. (There are other solutions; I disliked this one the least.) With real font support I could address the font directly. I know one issue is portability and that strike fonts move readily between platforms. Maybe there should be some way to: * Query the current platform for fonts with certain characteristics. (Answer all serif, answer all monospace, answer all bold Courier, etc. X-Windows has a mechanism for doing such searches that might be useful to look at.) * Specify that a certain font is wanted; it then acts like a built-in font. * Squeak then asks the platform to draw the characters. There are issues wrt moving an image to a new platform, but I think they can be handled so long as 'Squeak itself' uses built-in, portable fonts. Maybe I'm all wet here, with a quickly proposed solution that might not work. Regardless, there needs to be SOME solution to the Squeak font problem. The current font support sucks. The TT converter doesn't work on a Mac, it does work on Windoze but only at 32 point and above. It doesn't fix the problem. One cannot claim to have the worlds greatest multimedia content builder, then admit to having only three fonts with fixed sizes. Dave Chris, thanks for reminding me that I've been going to complain too.
