Ok i replaced the squeak VM 3.9.8 I used with squeak-vm-3.9-12olpc4 VM you said and it gives me input greek characters ... BUT :::: There are no tonos (´) or (¨) - there are squares in their places.When you press Insert key again a square appears, etc. Also copy/paste does not support greek. (look icon1.jpeg) On Windows there is no such problem. 3. Another problem that appears on (Windows/Linux) is with the translated words in the supplies main menu. Only the icon text (Κείμενο in greek) appears correctly). The others (Object Catalog,All scripts,Rectangle, etc return ????)(look icon2.jpeg) However when i open this menu Object Catalog there is no problem and all icons appear correctly. (look icon3.jpeg) Also in Connections in Object Catalog ???? appear in icon Labels and Titles (look icon4.jpeg) Finally i must tell that i changed all fonts to DejaVuSans that support greek from World/Appearance/system fonts/.... Thanks John Spyronis.

[Etoys] TextMorph auto printIt
by Karl 17 Dec '07

17 Dec '07

I have been doing some calculation stuff and have been using TextMorph and printIt as a calculator. It works great if you know how to printIt so I thought it would be cool to have a calculator widget that printIt on enter/return. What do others think ? Karl

[Etoys] The behavior of set heading is changed subtly
by Yoshiki Ohshima 15 Dec '07

15 Dec '07

Hello, Lately, we are fixing various bugs reported on trac and elsewhere, and one of these items is: http://dev.laptop.org/ticket/5214 (Try the example project made by Abe-san.) The simplest fix was to remove some logic that ignores the attempt to set a new heading value if it is "close to" the old value. The logic was from old days and we (collectively) cannot really see the reasoning behind it. We can take the check out (and the change is pushed to the update stream already), but there is a small risk. The risk is that some existing projects may change their behavior; if your program depends on the old behavior, where if you set a value to heading but it actually doesn't change it sometimes, it could be a problem. Also, the calculation of heading after an object bounced at the edge is changed. This is similar but more risky because in the old behavior the heading was rounded. If your project uses equality on the heading value and bounce, this could be a problem. (Now, we have the function tile to "round" the value, so one could create a proper script with it.) Please let us know if this change causes a trouble. Thank you! -- Yoshiki

[Etoys] Smalltalk development on XO
by Yoshiki Ohshima 15 Dec '07

Hello, I wrote a little wiki page that explains how to start and do Smalltalk development on XO. It is still "draft" status, but hopefully it gives interested people something to look at: http://wiki.laptop.org/go/Smalltalk_Development_on_XO Any comments are welcome. Thank you! -- Yoshiki

[Etoys] New OggPlugin (for windows)
by Takashi Yamamiya 15 Dec '07

15 Dec '07

Hi Karl, I built new OggPlugin. http://etoys.laptop.org/svn/trunk/OggPlugin/OggPlugin.win.zip It should solve the VM crash bug with large sound data. Even if you give vorbis a huge sound, the plugin divides it into small chunks before encoding/decoding. It also makes performance better, so I'll test it linux and mac platform with new source code later. Cheers, - Takashi

[Etoys] Greek and other languages support
by Yoshiki Ohshima 13 Dec '07

13 Dec '07

Hello, It took more than I thought/wanted, but I'm now working on the language support issue. As a start (of many starts), I pushed some changesets to the etoys 2.3 stream and made a "font file" from DejaVu font. All DejaVu fonts would make the image many dozens megabytes bigger, but the "font file" only covers the characters covered by CP1253 and ISO 8859-7, all of DejaVu minus SansExtra make the image only 5MB bigger. I tested it on Windows with Squeak 3.10.6 VM and on OLPC with squeak-vm-3.9-12olpc4. I managed to input greek characters, and copy and paste them. For those who are interested in, please try the following. On Windows: 1. Make sure that you have 3.10.6 VM. 2. Fully update your (developers version of) etoys 2.3 image. 3. Download http://tinlizzie.org/olpc/fonts/GreekTT.out and place the file at the same directory with the image. 4. Evaluate: TTCFontSet installExternalFontFileName: 'GreekTT.out'. to load the font file. 5. Evaluate newID := LocaleID isoString: 'el'. t := InternalTranslator newLocaleID: (LocaleID isoString: 'el'). NaturalLanguageTranslator translators at: newID put: t. Locale switchTo: (Locale localeID: (LocaleID isoString: 'el')) in a workspace. 6. From the appearance menu in the World menu, set the fonts to one of these DejaVu fonts. Let's say "default text font" for a start. 7. Open a new workspace and type something. On XO: 1. Make sure that you have squeak-vm-3.9-12olpc4 VM. 2. - 6. Same as above. However, since the step 4. will take so long time, you might want to do it on a faster computer and then copy the image to XO. 7. from console, type "setxkbmap -layout gr" to switch to Greek mode. (For better switching etc., take a look at http://wiki.laptop.org/go/Keyboard_layouts#Greek_el. Switching the mode by Alt-shift didn't work for me, but it may work on some other configurations.) 8. Go back to Etoys, open a Works space and type something. On XO, we still have the problem with Alt-alpha, Alt-beta, etc. (i.e., keys with a modifier key doesn't do the right thing. On Windows, it seems to be working.) It is likely that there are many problems when you try to use it for real, but please let me know. The code I wrote while ago when I don't know Smalltalk well is hard to understand and messy and that prevented me to look it at. But I finally did. Luke, I know try to address Nepali. It is even a harder task, but I'll try... -- Yoshiki

[Etoys] TextStyle>>isTTCFont missing
by Luke Gorrie 13 Dec '07

13 Dec '07

Howdy Yoshiki! Sorry to be lazy and email instead of TRAC'ing, but I think there's a tiny slip in the latest update stream: TextStyle has no isTTCFont method but the new version of TTCFont class>>registerAll tries to call it. Consequence is debugger popping up during TTCFont registerAll. -Luke

When I try to encode a sound longer than a few seconds the VM crashes. Could be that the OggPlugin is old... This is on windows. Karl
