fullBounds off by one?
by subbukk 22 May '07

22 May '07

Hi, Why is: (fullBounds x) = (bounds x) but (fullBounds y) = (bounds y - 1) for aSystemWindow (e.g. Workspace). This is causing a gap along the top in a snapshot image (see attachment). The problem does not occur for RectangleMorph. Is this a bug? .. Subbu

[ANN] ShoreBaseModel - Magritte class designer and code generator
by Pavel Krivanek 22 May '07

22 May '07

Hi all, I've created small class designer and code generator for Magritte. You may see the initial version in action here: http://comtalk.net/public/tmp/shorebase1.htm (flash demo) and download here: http://www.squeaksource.com/ShoreBase.html (package ShoreBaseModel). The editor requires latest versions of Magritte, Seaside 2.8a, Scriptaculous and ShoreComponents *How it works* The designer is based on Magritte meta modeling - it's very similar to PierForms. The Magritte model is modified a bit. When you finish the model design, the class and its Magritte descriptions are generated. The code tries to be as short and readable as possible. The only data source for the designer are existing source codes. That means that you may re-edit the classes that were generated before only from the sources. Currently the manual changes are not handled. *More complex example* In some cases the class design must be more complex. The example can be the class element (description) where the user can choose some system class: - create new Single-Option element - remove the default value of the element named Description (button Remove) - choose Description type to Class - press button Create - press button Save. Here you edited the referenced description. This description doesn't need description name - set Description name to "cls". The description name is used for the name of the generated description method. It's not required (see above) but the code generation will not work without it here. - set Accessor type to auto and name it "cls". The other kinds of accessors are possible. The selector accessors have getter and setter separated by space, the next kinds use Smalltalk expression - set Label to "Class" - set priority to 10 - set Required - set Options to: "Smalltalk allClasses" and set "code" - press Save - press Generate The generated description source code is descriptionCls ^ MASingleOptionDescription new autoAccessor: #cls; reference: (MAClassDescription new label: nil; undefined: nil; propertyAt: #descriptionName put: nil; yourself); options: [Smalltalk allClasses] asDynamicObject; label: 'Class'; priority: 10; beRequired; undefined: nil; propertyAt: #descriptionName put: 'cls'; yourself If you will edit the options code next time, the source will by decompiled. The description created by hand would probably look like: descriptionCls ^ MASingleOptionDescription new autoAccessor: #cls; priority: 10; label: 'Class'; beRequired; reference: MAClassDescription new; options: [Smalltalk allClasses] asDynamicObject; yourself Custom validators aren't supported now. Please try to play with it and report bugs. You may write more tests too ;-) Cheers, -- Pavel

Universes or dev image problem?
by David Shaffer 22 May '07

22 May '07

In squeak-dev-beta-123 image if I load Seaside from the Package Universe Browser I get a walkback when trying to load 'KomServices-gk.3.mcz' The walkback is 'Error: file is too short' and, on inspecting the file it simply contains the text: server aborted early I'm not sure if this is an issue with the Universe config, the dev image or simply a temporary failure downloading this file.

I don't know, .so's/DLL's, not to mention Unixy daemons, are actually plenty to allow you to replace subsystems without rebooting the whole computer. You reboot the subsystem, but not the whole machine. Linux folks update all the time without rebooting. So it seems to depend on the culture as much as the technology. Some programmers make their subsystems replaceable, and others do not bother and make you reboot. Lex

squeak-(dev/web) browse protocol
by Jimmie Houchin 22 May '07

22 May '07

Hello, I am using the squeak-dev squeak-web images. Thank you Damien. But I am not finding the browse protocol in the browser menu in some of the browsers. I love using the browse protocol as it gives me all the methods available to the class up to a chosen super class. So much nicer than looking at each individual super class up the hierarchy. I've notice some of the browser options have the browse protocol option, some do not. It seems to me that it would be nice if all browsers supported such. When I open "class browsers" for the first time it presents me with the options of Browser, PackagePaneBrowser, RefactoringBrowser and OBSystemBrowserAdaptor. When I select one it seems to become the default. How can I change the default? Also, it seems that I always have the PackagePaneBrowser and the RefactoringBrowser available in the "open" menu, but not the Browser or the OBSystemBrowserAdaptor. Would it be reasonable to always have all the browser options available in some menu, until such a time that we have a consolidation of browsers or the selection of a chosen browser which fulfills everyones desires. :) Thanks. Jimmie

Well, as long as you're asking... http://www.symbolics.com/Genera-1.htm (note feature bullets) How this was done, exactly, for class defs: http://www.lispworks.com/documentation/HyperSpec/Body/07_b.htm http://lisp.org/mop/concepts.html#reinit-class If I recall, there was an implementation of Objective-C that also updated existing instances when you changed class shape, but I never (knowingly) used it.

If only they did dynamically bind ... far too many changes require a reboot and this means that they are still using linking loaders to do quite a bit of integration of changes ...

While mature dynamic languages including Smalltalk, Lisp, Scheme, Self, and Prolog continue to grow and inspire new converts, a new generation of dynamic scripting languages such as Python, Ruby, PHP, Tcl, and JavaScript are successful in a wide range of applications. DLS provides a place for researchers and practitioners to come together and share their knowledge, experience, and ideas for future research and development. DLS 2007 invites high quality papers reporting original research, innovative contributions or experience related to dynamic languages, their implementation and application. Accepted Papers will be published in the OOPSLA conference companion and the ACM Digital Library. Areas of interest include but are not limited to: ************************************************* * Innovative language features and implementation techniques * Development and platform support, tools * Interesting applications * Domain-oriented programming * Very late binding, dynamic composition, and runtime adaptation * Reflection and meta-programming * Software evolution * Language symbiosis and multi-paradigm languages * Dynamic optimization * Hardware support * Experience reports and case studies * Educational approaches and perspectives * Object-oriented, aspect-oriented, and context-oriented programming Submissions and proceedings *************************** We invite original contributions that neither have been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Papers are to be submitted electronically at http://www.dcl.hpi.uni-potsdam.de/dls2007/ in PDF format. Submissions must not exceed 12 pages and need to use the ACM format, templates for which can be found at http://www.acm.org/sigs/pubs/proceed/template.html.
