Hi all, this tiny goodie removes all entries without references from Undeclared. Maybe this should be called after every file in.

[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>>

Re: [Modules] C and Smalltalk modules
by Anthony Hannan 10 Mar '03

10 Mar '03

Hello again, here's a simpler description of the modules I presented in my previous email. A module is an object that introduces new objects and specifies changes to existing objects in imported modules. When a module is linked its changes are applied to the existing objects. When a module is unlinked its changes are undone. A module is automatically linked when a process that has the module in its environment becomes active. Process has a new instance variable called environment that points to a module. A module is IN an environment iff the environment directly or indirectly imports the module. A module is automatically unlinked when a process that does NOT have the module in its environment becomes active. Pointers that cross module boundaries are converted to identifiers when unlinked and converted back to pointers when linked. For example, a class Foo introduced in ModuleB may have its superclass Bar introduced in ModuleA, an import of ModuleB. When ModuleB is unlinked, Foo's superclass will contain the identifier #Bar. When it is linked back it will contain the class Bar. If there is no global pointing directly to Bar, its identifier will specify a path to Bar from a global, for example #Classes.Bar. Modules only deal with objects and identifiers and is independent of any class (or classless) structure. Thanks, Anthony

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

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.

I got 92 errors, all of which seem to be due to the fact that I am missing certain .st files--which I assume are the fabled Refactoring Browser test data files.

I certainly will, as soon as I figure out how to use SM to package files that should be *not* filed in, but just put in the default directory. Would SAR be useful for this?

RE: {bad habits] Squeak for Windows - Ctrl instead of Alt key
by G.J.Tielemans＠dinkel.utwente.nl 11 Jul '02

11 Jul '02

<snip> I think this might be going too far... the default key bindings should probably be the same for Squeak on all platforms, otherwise there'd be confusion when reading documentation, etc. You should consciously change a setting to get different bindings. (An end-user runtime is a different story... there it might make sense to detect the platform and set the key bindings appropriately.) - Doug Way dway(a)riskmetrics.com Ger: 1. which documentation 2. Wasn't the design of the red yellow and blue buttons not just the solution for platform (mouse) independency?

Sunit explained
by ducasse 18 Jun '02

18 Jun '02

Hi I realized that lot of people were convinced about the need of tests but were not really aware how to use SUnit. (Also lot of people are too buzy to bet on the possibility to change their applications, they prefer to be blind and say: "I would love to write tests but I cannot afford to spent that much time") Then they were not really using it. Today I spent (too much time) to write an english version of an article I wrote in french recently. So there is certainly lot of mistakes ;( The article is available at http://brain.cs.uiuc.edu/StWritersCoop/First+Submissions Feel free to send me comments. I sincerly hope that more people will use SUnit so that we can change squeak with more and more ease. Stef

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.

RE: XML Parser choice (was Re: [ENH] ??? MD5 in Squeak.)
by Richard A. O'Keefe 25 Mar '02

"Andreas Raab" <Andreas.Raab(a)gmx.de> wrote: Code size isn't but complexity is. Usually these two go hand in hand and therefore it's no strange argument at all. In fact I'd argue that programmer time is (in this particular case) mostly dictated by the complexity involved in the parser itself - most people will want to do pretty simple stuff. But this is precisely why a non-validating parser would be a *bad* idea. Non-validating parsers are easy to write. But if anyone were to try to process DocBook using Squeak (hey, guess what I'm trying to learn?) such a parser would be as much use as an Apple ][ simulator (maybe less, come to think of it). If you really want to avoid complexity for people trying to use XML in Squeak, then choose a parser than implements *ALL* of XML, not just the dead easy bits. Do the hard stuff *once*.
