Exactly, Squeak is the place to try out new ideas, I also applaud the decision and can't wait to have traits in the language. Much kudos to those pushing the limits and seeing what's possible, someone has too. Ramon Leon

Traits Refactored Collection image
by stéphane ducasse 31 Aug '05

31 Aug '05

Nathanael put back the image containing the traits refactoring (notice that if you use a mac the browser may behave strangely because of a platform dependent small issue in the bytecode analysis that nathanael did at tthat time. Now this is fixed). http://www.iam.unibe.ch/~schaerli/smalltalk/traits/ OOPSLACollectionRefactoring.zip

I'm currently building a website using Ruby-on-Rails (though I'd probably have been happier with Seaside if Squeak ran on my architecture), and mixins as implemented in Ruby seem to answer all the questions that multiple-inheritance fans ask. Also, when *will* traits make it into the standard image? ../Dave

a Menu like a TelefonMobil Menu?
by EL Marjani Radouane 31 Aug '05

31 Aug '05

Hi, Thank you for yours Help and yours Answers. I try to make a menu like a Telefonmobile menu.Then with a click on a Button I must swing between the Items this Menu. I have tryed with MenuMorph but the Problem hier, I can just with mouse clicken, but I want that I click on Button 'Taste' and then I can swing between MenuItems. My Code: TelefonbuchMenu := MenuMorph new. TelefonbuchMenu addStayUpItem. TelefonbuchMenu position: 72@112. TelefonbuchMenu title: 'Telefonbuch 1.2'. TelefonbuchMenu add: 'New Adress' action:#displayChangeDown. TelefonbuchMenu add: 'VisitenKarte' action: #displayChangeDown. TelefonbuchMenu add: 'Gruppe' action: #displayChangeDown. TelefonbuchMenu openInWorld. self handySiemens addMorphFront: TelefonbuchMenu. I hope someone can make a Hepl. Thanks, Regards.

Re: [Q] Maui, can I run example or demo?
by Chris Muller 31 Aug '05

I left one step out. > While still hovered over the one you just made small, press "b" to browse its > hierarchy. DirectoryEntry pops up. Drag #name and #fileSize to the one you > made small. Now Shift+click for its tool menu and select "as list entry". Before you can do the next step, below, you have to remember the just-created list-entry. So Shift+right click on the list entry and select "manage views...". Place the mouse-pointer into the first black-box of the message, "Remember view as: [ ] for all kinds of: [ ]" so that the box highlights green. These black boxes are "parameter-holders" for invoking messages that require parameters. Now type 'list entry' INCLUDING the quotes in the left box. You may drop any object or type any valid Smalltalk expression into them. You may click in the right box to select DirectoryEntry. Because both boxes are populated, the message is automatically executed. You may now close this "dialog" by pressing "x" while the outer blue box is highlighted. NOW, you may do this step, below.. > Finally, right-click on the actual Collection object, carefully getting > outside > that black border (its ScrollPane or something) but still on the Collection > so > that it is outlined in green (this part is a little tricky), and select > "elements view | list entry".

Modules and more.. :-) (related to Traits, Self, Ruby)
by Dirk Wessels 31 Aug '05

31 Aug '05

Hi all, I have been working on my own computerlanguage based on smalltalk (and little bit of everything). I see much of the discussions here related to the same problems I have been solving. At least I hope I solved them.. -------Proposal 1 use modules to manage behaviour------- 1) Managing complex behaviour would be more structured by using modules.. All related methods of different classes can be defined within one module. Modules can really helps on the long term development. Modules are first defined using a special fileIn/fileOut format, to enable incremental separation of the image. ------Proposal 2 use text to define modules and classes--------- 2) defining modules and classes First I would like to start to introduce a script which defines the modules and classes.. MyFirstModule := << Module | MyPoint := << Class | varX. varY. #x ^varX. #y ^varY #x:x varX:= x. #y:y varY:= y. # >> MyStorage:= << Class | #storeInto:File #loadFrom:File # >> >>. This far it is simple.. I use a construct definition << >> to define anything in my system.. There are many different constructs possible: Module, Class but also Application or DeviceDriver or Primitive. These could all be meta-constructions. You probably have some nice idea's too :-) ------Proposal 3a define inheritance by including behaviour--------- 3) defining imports and inheritance The Classname<<>> construct defines extension within current construct, i.e. inheritance... The identifier<<>> construct defines a local extension. Is currently used for imports. MySecondModule:= << Module | import<< MyFirstModule. >>. version:= 3; MyStoredPoint:= <<Class| MyPoint<< >>. MyStorage<< #storeInto:File File writeVar:varX. File writeVar:varY. #loadFrom:File varX:= File readVar. varY:= File readVar. # >>. >>. >>. Some may notice that: MyFirstModule<< >> could also be an import definition.. ------Proposal 3b define inheritance by extending behaviour--------- The class can als be extended using a similar syntax MyThirdModule:= << Module | import<< Math. MyFirstModule. >> MyPoint:<< "this is an extension" MyStorage<< "I inherit from MyStorage again" #storeInto:File File writeVar:varX. File writeVar:varY. #loadFrom:File varX:= File readVar. varY:= File readVar. # >>. >> Integer:<< #@ y | newPoint | newPoint:= MyStoredPoint new. newPoint x:self; y:y. ^newPoint. # >> >> ------Proposal 4 change grammar a bit for some typedefinitions--------- I'll use the example below //In my own language I use a slightly different sytnax which enables typedefinitions.. //And even parametric types. //I'll just add the different syntax for the good of discussion.. //I wonder if anyone here really cares about what characters are used for certain definitions, //as long they are usefull.. // // // MyPoint:= <<Class| // varX; // varY; // "x":={ varX; }; #methods are defined as blocks // "x:" := { ?x | varX:= x; }; # ? defines input, ! defines output // // "y":={ !result| result:= varY; }; // "y:":= { ?y | varY:= y; }; // // varZ: Double,Integer; # type definitions.. // # anything that implements Double or Integer can work // count:: Integer32 =0; # strict type definition and initialisation // // # I add a z here to show some more options // // "z"(!d:Double,Integer):={ d:= varZ; }; // "z: ?d:Double":= { varZ:= d; }; // // ":Point":= { Point newX: varX andY: varY; }; // #defines point as replacement if necessary // #often easier than inheritance.. // // >> // // #Since the types and methods are binded at runtime, // # we can may constants in definitions too.. // // Integer:<< // "factorial:?0":= {1}; // "factorial:?n:Integer":= { n*(n-1) factorial; } // >> // // Integer:<< // "divmod()":(?x:Integer;!div,!mod:Integer):= { div:= self//x; mod:= self\\x }; // #call with: 5 divmod(?x:= 3; resDiv:= div; resMod:= mod); // >> // I don't know how to do such definitions in current smalltalk grammar. I thought of using @ for types.. and :: for output, but these symbols differ too much from other languages.. ----------------------------- These modules reduce a bit of complexity of modules and behaviours (traits, inheritance). The script of managing projects and fileIn. The fflexible typesystem might add to speed and such.. I know the problems are not all solved yet, but it is just a start.

Jabber Missing?
by Liz Wendland 31 Aug '05

31 Aug '05

Hi, I am interested in looking at the Squeak Jabber package, but all the links I find are broken. eg: http://www.squeaklet.com/IM/Jabber-2.0b.cs.gz Is there a reason this project has disappeared or is it still available? Thanks! Liz Wendland

Bargraph.st
by Mart-Mari Breedt 31 Aug '05

Hi, Does anyone know where to find or have a copy of the bargraph.st file. I think the link to the Bargraph component (http://chompion.mine.nu/images/squeaken/bargraph.st ) on SqueakMap is out of date. Thank you, Mart-Mari
