How to Install true type font as a true type font and not as strike font
by Himanshu Garg 26 Jul '05

26 Jul '05

Hi, I have dragged and dropped a true type font for an Indic script into Squeak. Because it is converted to a strike font, it doesn't show the glyphs correctly. In particular those glyphs that must overlap on the previous glyph, don't show completely. Their parts that overlap go missing. I am guessing that this is because it gets converted to a Strike font. Could you tell me if there is a way by which I could use the true type font as is. That's because Microsoft word and other Microsoft Windows applications show the text fine with the font. Kindly help. Is there any other way out. Any url's for reference would also be of great help. Thank You, Himanshu. --

[ENH] ExplorerSpeedup-efc

from preamble: "Change Set: ExplorerSpeedup-efc Date: 21 July 2005 Author: Eddie Cottongim Makes scrolling smooth in SimpleHierarchicalLists faster by using a binary search to only draw visible elements. TransformMorph has also been given this ability through an extension. IndentingListItemMorph has a minor change to prevent an unnecessary copy of its owners submorph collection. The object explorer remains slow to open initially. Try it out with (1 to: 10000) explore. "!

[ENH] submorphsCleanup-efc
by cottonsqueak＠earthlink.net 26 Jul '05

26 Jul '05

from preamble: "Change Set: submorphsCleanup-efc Date: 24 July 2005 Author: Eddie Cottongim In profiling for speed, I've noticed that a common culprit for poor scaling to large numbers of morphs is unnecessary use of #submorphs where the whole collection is not actually needed. There is often a trivial replacement that can spare doing the copy, and is probably better style. #copy is very fast, but it can introduce O(n*n) performance that is noticable when you have a lot of morphs, the machine is slow, or both. Also the callers tend to send #submorphs two or three times in one method!! I've gone through what looked like the core morphic classes and carried out transformations that looked trivial. I haven't touched more complicated cases. The ones I can't get without adding methods or rewriting the caller are the complicated Collection selectors that don't have a ready equivilent in Morph, and direct submorph access by index, which Morph doesn't have for some reason. The following conversions have been made: submorphs size -> submorphCount submorphs do: -> submorphsDo: submorphs last -> lastSubmorph submorphs first -> firstSubmorph submorphs empty -> (not)hasSubmorphs submorphs indexOf: -> submorphsIndexOf: Those on very slow machines may see some benefit from this in normal use. Others may only benefit in extreme cases with a LOT of Morphs. "!

hi everyone, I am working in an educational institution in India. We use squeak to improve the level of science and maths education for over 2 years now. We train teachers to develop multimedia content for rural primary schools. In this process we face some problems. -- De-link the sound(sound should not overlap):- In Book Morph the sound is getting overlaped with the previous morph we do not know how to stop that sound getting overlaped. -- Publish audio gets corrupt:- when we are publishing the content the audio is getting corrupted.. -- Retrieve objects from the trash:- please explain how to retrive the objects from trash. thanking you in advance, K.Prabhakar If anyone knows the answers to these problems, please send us.

Magma update
by Chris Muller 25 Jul '05

25 Jul '05

Magma has come a long way in the last year. While there is still work to be done, feedback has been fairly positive lately. Some have specifically asked for disaster-recovery feature. I am happy to announce this is now available. Magma is slowly becoming a usable database for Squeak. I have also freshened the Swiki pages with current information. See http://minnow.cc.gatech.edu/squeak/2665. Those interested in discussing Magma in detail should subscribe to the new Magma mailing list. To subscribe, just send an e-mail to magma-subscribe(a)discuss.squeakfoundation.org. Major announcements (like this one) will be cross-posted to squeak-dev. - Chris

About Learn programming with robots

Hi all I regularly receive emails of people thanking me for my free book collection and for my new book. I thank you for your warn words. Now I can tell you that it was ***difficult*** to write and to get published the new book (I changed publishers in the process). I wrote around 900 pages and I'm wondering what I will do with the material that I have. Now I will not be able to publish a new one if the current one does not sell. So if you appreciate the books do not hesitate to advertise it around. Stef contact me if you have specific needs, I'm ready to translate the environment in various languages....

Pretty print + shout colors in the same time ?
by Damien Cassou 25 Jul '05

25 Jul '05

Hi, I'm wondering if it is possible to have syntax highlighting with Shout + pretty print (at least indention) with the refactoring browser. What I can have now, is colors if I use 'source' in the menu of RB, or pretty print without colors if I choose 'prettyprint'. I want the two of it. Is it possible ? Thanks -- Damien Cassou for Software Composition Group in Berne
