How to use Search Browser?

askoh — 2008-08-28T20:42:03

I recently discovered the Search Browser. But I cannot find much information about it. What are the search string formats to find implementors, classes, strings, etc? How to use wildcards? Can it be made case insensitive? Thanks, Aik-Siong Koh

Hi Maximiliano, "Four slightly different intercalary schemes have been described in the literature..." see http://www.phys.uu.nl/~vgent/islam/islam_tabcal.htm Since (August twentieth, 2008) asIslamic returns the 17th in your example it seems like the book describes either type Ic (‛15’, civil]) or type IIc (‛16’, civil) from the above web page. Microsoft is using the "Kuwaiti Algorithm", see http://en.wikipedia.org/wiki/Kuwaiti_algorithm Thanks. Found it deep in the FAQ section of the SqueakSource page. (Expected it in the projects Overview as in http://www.squeaksource.com/Seaside29.html which states "Code commited to this repository will be automatically under MIT license.") Bye Torsten

running test suites

Esteban Lorenzano — 2008-08-27T12:06:54

Hi, I'm looking for a simple way to run test suites and have results like test runner... and test runner does not understand suites (just cases). Is there a "suite runner" somewhere, or maybe I'm using test runner wrong? Thanks, Esteban

Depending on the underlying arithmetical calendar type this should return either Sha'ban 17, 1429 or Sha'ban 18, 1429 or Sha'ban 19, 1429 See http://www.phys.uu.nl/~vgent/islam/islam_tabcal.htm Is the library able to handle different intercalary schemes? Whats the license of the code? Found no info on Squeaksource about that. Thx Torsten

how to tell when Squeak's GUI is active?

Craig Latta — 2008-08-26T23:33:34

Hi-- I'm using Growl/Snarl[1] to post notifications from Squeak. Of course, they're somewhat annoying when Squeak is already the active host application. Is there some way to tell whether Squeak is in the foreground or background, as far as the host window system is concerned? I only care about getting the user's attention when some other host application's GUI is active (and thus possibly obscuring Squeak's GUI). thanks! -C [1] http://en.wikipedia.org/wiki/Growl_(software)

Maximiliano Taborda — 2008-08-26T20:20:25

Hi. We uploaded to SqueakSource (for Squeak) and to the Cincom Public Repository (for Visualworks) a new release of the project called "Chalten" (2.0) that is our implementation of the Time Domain (not only of the Gregorian Calendar now). This model was born as a representation of the Gregorian Calendar, and, in this last version, the model support the Gregorian, Julian, Islamic an Hebrew Calendars. Many refactorings was done from the original model to get this last version wich reifyes many concepts of the Time Domain that Smalltalk-80 does not; for example: day, day of month, month of year, month, year, calendars, time zones, filters over the timeline, etc.. The main objective of this model is to easily, and in a "SDL way", solve problems of the Time Domain that are not easy (or impossible) to do with the Smalltalk-80 abstractions. t provides also some concepts that are useful for financial application, among others, like relative dates and time line filters. This model also uses the units models (Aconcagua). Because it uses the units model, there are some concepts that are not useful anymore, like Duration, because a Duration is a Measure of time. The model covers many concepts of the Time Domain, but lacks of some abstractions; for example, the representation of the leap second. It comes with more than 1600 tests (all green). Here are some examples: "Create some time entities" August twentieth, 2008 --> Creates an instance of the gregorian Date for 20/08/2008 August twentieth --> Creates an instance of the gregorian DayOfMonth for 20/08 August, 2008 --> Creates an instance of the gregorian MonthOfYear for August of 2008 "But, not only gregorian entities" Shaban seventeenth, 1429 --> Creates an instance of the islamic Date for 17/08/1429 Shaban seventeenth --> Creates an instance of the islamic DayOfMonth for 17/08 Shaban, 1429 --> Creates an instance of the islamic MonthOfYear for Shaban of 1429 JulianAugust seventh, 2008 --> Creates an instance of the julian Date for 07/08/2008 JulianAugust seventh --> Creates an instance of the julian DayOfMonth for 07/08 JulianAugust, 2008 --> Creates an instance of the julian MonthOfYear for August of 2008 Av nineteenth, 5768 --> Creates an instance of the hebrew Date for 19/05/2008 Av nineteenth --> Creates an instance of the hebrew DayOfMonth for 19/05 Av, 5768 --> Creates an instance of the hebrew MonthOfYear for Av of 5768 "Converting dates between diferents calendars" (August twentieth, 2008) asIslamic --> Return Sha'ban 17, 1429 (August twentieth, 2008) asHebrew --> Return Av 19, 5768 (August twentieth, 2008) asJulian --> August 7, 2008 (julian) (Shaban seventeenth, 1429) asHebrew --> Return Av 19, 5768 (JulianAugust seventh, 2008) asIslamic --> Return Sha'ban 17, 1429 (Av nineteenth, 5768) asGregorian --> August 20, 2008 (gregorian) "Measuring distances" August twentieth, 2008 distanceTo: December thirtieth, 2008 --> Return an instance of Measure <132 days> Shaban seventeenth, 1429 distanceTo: Muharram second, 1430 --> Return an instance of Measure <132 days> Av nineteenth, 5768 distanceTo: Tevet third, 5769 --> Return an instance of Measure <132 days> "Also, measuring distance expressed in diferents way (calendars)" August twentieth, 2008 distanceTo: Tevet third, 5769 --> Return an instance of Measure <132 days> Shaban seventeenth, 1429 distanceTo: December thirtieth, 2008 --> Return an instance of Measure <132 days> Av nineteenth, 5768 distanceTo: Muharram second, 1430 --> Return an instance of Measure <132 days> "Collect some entities" (ChaltenYear number: 2008 calendar: GregorianCalendar) months collect: [:monthOfYear | monthOfYear lastDate] --> Returns all the last dates of the 2008 months.

SandstoneDb question

Esteban Lorenzano — 2008-08-25T20:21:35

Hi, I'm using SandstoneDb for a project... and I have this (one-to-many) scenario: a) Product as Parts b) a Part can be owner by a Product, or can be orphan so, I have two roots: Product and Part well, by design, Sandstone does not allow me to make a recursive commit, and I have to make that commit by hand, something like this: self product partsDo: [ :each | each isNew ifTrue: [ each commit ]. self product commit. but... I need this behaivor in many parts of my environment, so I rewrited #commit, this way: Product>>commit self partsDo: [ :each | each isNew ifTrue: [ each commit ]. super commit. My question is: is this design right? Is there another -cleaner- way to do this? Thanks in advance, Esteban pd: maybe #commitWithRelations is better than overwrite commit?

ESUG conference 2008 started

Noury Bouraqadi — 2008-08-25T07:44:30

Dear Smalltalkers, The ESUG conference at Amsterdam (The Netherlands) is started. We have 171 registered people. This our new record, the previous one was in 2004 with 114 people (so +57 !). So, this is cool to have so many smalltalkers. This is a great opportunity to meet other Smalltalkers, attend high quality talks and demos. You'll find out more about what happening here at Amsterdam, talks slideshows, and other media related to the conference on the site below. You already have PDF files of the 20 submissions to the ESUG Technology Innovation Awards. BTW 20 submissions to the ESUG Awards is also a new record. http://vst.ensm-douai.fr/Esug2008Media Cheers, Noury ------------------------------------------------------------------ Dr. Noury Bouraqadi - Enseignant/Chercheur Responsable de l'enseignement de l'informatique ARMINES - Ecole des Mines de Douai - Dept.

MillisecondClockMask value

Igor Stasenko — 2008-08-22T18:14:12

I just stumbled over a trap with MillisecondClockMask value which is 16r1FFFFFFF while in Hydra code i using another mask - 16r3FFFFFFF Can anyone tell, why mask is 1 bit shorter than maximum safe value? 16r3FFFFFFF << 1 + 1 ---> 16r7FFFFFFF - fits in positive smallint What you think, what mask is better to keep? I don't think that changing a mask will make any difference to language side. Because this mask used only together with millisecond clock values , which in C is 32 bit wrappable counter. Losing some high bits don't makes much difference , but i think using 16r3FFFFFFF would be better, or if not, please, tell me why.

Fullscreen UI

Hi Udo, have a look Tansel's minimal UI at http://wiki.squeak.org/squeak/6032 in the section "Minimal UI For Embedded Systems, Mobile computing and Kiosks" Code/Image is at http://www.squeakonline.com/downloads/cedemo.zip. or at Project "Tweak" - a rewrite of the morphic UI for Croquet: http://wiki.squeak.org/squeak/3867 Bye Torsten

Fullscreen UI

Udo Schneider — 2008-08-22T10:36:04

Hi, I want to create a fullscreen UI on my own for learning/testing some concepts (and no - I have no plans to do a fully featured UI). I neither want to rely on Morphic nor MVC. My idea is to simply "get" a form representing the Display and a Sensor providing all the kbd/mouse events. Where do I have to hook in? Any pointers? CU, Udo

[ANN] MC Converter 1.1.31

Colin Putney — 2008-08-22T07:03:25

Hi all, MC Converter is a simple utility for converting MC 1.x repositories into MC 2.0 repositories. It's the tool I used to take MC 2.0 self hosting, and I've successfully used it to convert some large-ish projects like OmniBrowser. With all the versions of MC 1.x floating around out there, however, I do expect that there will be some issues and incompatibilities. If you do run into problems converting repositories, please let me know so I can help sort them out. Download it from here: http://www.wiresong.ca/static/releases/MCConverter-current.st To convert a repository, do the following: - build an image that contains both your preferred version of MC 1.x and MC 2.0 - create directory repository containing all the MC1 versions you want to convert - file in MCConverter - write a conversion script - see MDIncrementalConverter>>convertMC2 for an example - run the script to convert the repository - open the new repository in an MC2 repository browser to examine the results Colin
