.NET Bridge
by Bob.Cowdery＠CGI-Europe.com 23 Mar '06

23 Mar '06

Hi I have some code in C# that I want to port to squeak but it's quite a lot of work so as a quick fix for the time being I am trying to use the .NET bridge. Although I can get it to work with the examples that use built-in types I can't get it to work with an assembly I have built. Before I go into detail is there anyone out there who is successfully using this with their own assemblies.

about translations
by Alberto Berti 23 Mar '06

Hello squeakers, i'm squeak newbie and i often watch at squeak's progress always with the hope of being able to drop the barrier of it's scarce documentation doing something using something useful with it and contributing back to the community which has create this incredble environment. Some qualities of squeak repeatly led me to involve some amount of time in it, always without so much luck. I think it could be the best environment for the kids i know to learn programming, also my syster works with neuropsychiatrysts to help impaired children learn by using some kind of commercial tools which let the operator create, merge and show a kind of simple iconic alphabet that helps the learning of concepts (if i recall, she call it something like 'augmentative communication'). The fact that these tools are commercial inhibits the spreading of such "advanced" learning tecniques. I think that a similar and even more powerful environment can be setup for the operator by using squeak. But i think also that a key need for squeak to be usable and adopted both by "normal" kids and by operators and impaired children is the translation of the standard environment in their mother tongue (e.g. italian for me). Recently, i got the time to also try out Tweak, which i find so good and much more understandable, even without so much docs:) , so i "revamped" my idea of contribute an italian translation to squeak, in order to try "teaching" it, to some extent. I do know and use some "standard tools" to deal with translations like gettext, emacs po-mode (and the others) and svn or darcs for versioning. With some friends we have set up a public repository of translations along with a complete wiki help to let non-developer people contribute to the translation process in a manageable way ( http://docit.bice.dyndns.org ) i do not known the reasons under "reinventing the wheel" with tools like the language editor when there are so many good tools to deal with translations, even with multi-byte character sets like japan's one. I can only immagine that these other tools don't represent the "squeak way" of doing things. However this not the point.. the point is that the "squeak way" of coordinate a translation between a group of people that want to contribute, like sharing in progress translation resources, isn't still clear to me nor it seems to be documented (it is?) and to be frank, it was not so simple to understand how to add an another language to the image, due to outdated docs. More than that, i have a group of people that want to contribute to the translation and they are already familiar with the tools above, so my willing is to reuse that infrastructure. I want to translate the squeak's standard full image, the one which is downloaded by the normal user most of the time, not the small-land image or the squeakland one, because it is the "default" image downloaded by a new user which approaches squeak. So my desire is to do the following things: 1) Learn how to add italian to the multiligual infrastructure; 2) do an export in gettext's po mode; 3) reuse stantard po tools and svn and the site docit.bice.dyndns.org to coordinate the effort; 4) import the translation back to the image; 5) prepare a squackmap package to let normal users load the italian translation; For the point 1), the swiki has very old informations, but i learned how to do that with the email from Yoshiki at http://lists.squeakfoundation.org/pipermail/squeak-dev/2006-February/100956… I downloaded that image and i found that it has and improved language editor with and added butto "new" which adds a new LocaleID and thus enables a new translation. The interesting code is: LocaleID isoString: 'it' Aside from having a specific button to do it, evaluating that code in a workspace even in the standard image does the right job, and then is possible to open a language editor for that language code. I'll update the swiki asap with this information:) The point 2) is much more difficoult though. I tried the gettext export both in the standard image and in the squeaklanddev's one withouth any luck. An error box comes up, saying that #GetTextExport is not a key into 'Smalltalk' dictionary (i think it's a kind of global one). a quick googling for that problem showed that there is a bug filed already for it at http://bugs.impara.de/view.php?id=1744 in stat 'new' since august. It says that the missing classes are available into the small-land image. How it's possible to highilight the differences between the standard image, the squeaklanddev one and the small-land one and backport these missing features to the standard one? I really do not know yet and i've still to read the doc if there is one on that subject so i tried another approach. I told to me.. "maybe if i can find a repository with the sources available as a monticello repo i can be able to load such missing parts from there and also track future development". So i visited Yoshiki's site, quite unuseful, and then SqueakSource site, looking for something interesting. I found the "LanguageEditor" project (http://www.squeaksource.com/LanguageEditor.html)! Wow "i found it", i've said to me! Sadly, after loading the code with monticello i found that it is quite old comapared to the features available on newer images! So finally my question is: there is a way to track sources of such a widely intersring topic like traslations in consitent or affordable way? do you publish your sources somewhere guys? I don't want to start a flame but it would be quite simple in other communities and generally translations and translation-infrastructure are considered a key thing to share in open source projects. thanks in advance, Alberto

[FIX] Squeak 3.9 / ProportionalSplitter-honor-boundaries
by John Pierce 22 Mar '06

22 Mar '06

Hi all, It's been a while since I've been able to do some programming. So I'm just dusting off my VM and here's a little changeset I worked up tonight that makes the new splitters in Squeak 3.9 honor the natural window boundaries. If anyone noticed, the splitters in Squeak 3.9 just let you go trucking off outside the window boundaries, and things get all goofy. This changeset should correct that if anyone is interested. Enjoy.

squeak and midi on linux [SOLVED]
by Cesare Marilungo 22 Mar '06

22 Mar '06

I just wanted to tell you that I've finally managed to do what I need. I can make squeak talk to PureData via OSC and control other MIDI apps from there. Anyway one of the most interesting uses of squeak (and music) I can think about is to make GUIs and front-ends for PureData patches. c. -- www.cesaremarilungo.com
