Linux and ttyUSB0
by Jon Hylands 13 Jan '09

13 Jan '09

Hi everyone, On my current robotics project, I'm using a gumstix verdex to talk over a USB to serial converter chip (FT232) to a serial bus. My brother Dave made up a new kernel driver for the gumstix, and when I plug in the chip it registers itself as ttyUSB0. For work I've done previously on Squeak on the gumstix, I've used standard serial ports, which map to ttyS0, ttyS1, ttyS2, etc, which correspond to port 0, 1, and 2 when I open the Serial Port in Squeak. However, I have no idea which port number ttyUSB0 corresponds to... Anyone got any idea? Thanks, Jon -------------------------------------------------------------- Jon Hylands Jon(a)huv.com http://www.huv.com/jon Project: Micro Raptor (Small Biped Velociraptor Robot) http://www.huv.com/blog

The state of Squeak I18n support: let's improve it
by Katerina Barone-Adesi 09 Dec '08

09 Dec '08

There has been a lot of excellent work done on Unicode in Squeak. Unfortunately, not all of it works 'out of the box'. I've started working on trying to figure out how to enable the basic operations (input, display, and copy/paste) for several languages. With the kind help of several Russian squeakers, I've managed to create relatively simple instructions on how to do so for Russian, which I've posted here: http://wiki.squeak.org/squeak/5773 ; I've personally tested the 3.10 instructions under Linux. However, getting to this point involved days of experimentation, including quite a lot of image hangs. The reason I created the documentation was that, despite reading everything on squeak.org and the mailing list archives about Russian and Cyrillic support, I still couldn't get it working - it took combining the instructions of two people who had had similar experiences, and the patches of two others, to have everything work, although there are some problems with garbage characters with copy/paste sometimes. A side effect of these instructions is that various accented European characters (such as à, å, ò, ö, ĵ, ñ, ç, č, ć, š, đ, etc - everything I've tried) work. This cursory testing suggests that Italian/French/German/Spanish/Swedish/Esperanto/Slovenian/etc operations also work after following the Russian instructions; they do not work by default. Perhaps more interestingly, Thai and Greek also work; Arabic nearly does, but only displays in its 'general Unicode' form (rather than correctly changing what appears based on the position of each letter in the word: see http://en.wikipedia.org/wiki/Arabic_alphabet for a better description). I'm now going through the same process for Japanese. Installing 'Japanese Environment Installer' (JEI) from SqueakMap only gave me a working display of Japanese characters, without working input or copy/paste. Possibly interestingly, direct input while using a Japanese keymap (with no input method) to type kana works with the Russian patches, but not with the JEI patches. Nothing using extra input method software works anywhere in Squeak in any configuration I've tried. Deadkeys also don't work. I would like to request help from all Squeakers who can input, display, and copy/paste text in languages which have characters or writing systems that don't appear in the languages mentioned above, and especially of those who have everything working with Japanese. Any instructions on how you did it would be greatly appreciated. I intend to keep documenting the simplest ways to currently set things up, which will hopefully have the side effect of making a baseline set of patches to have things Just Work become clear. Any reports of errata in the documentation, platform differences, or bugs are also extremely welcome. Thank you; Katerina Barone-Adesi

Cleaning up lava code and unsent messages.
by Jerome Peace 02 Dec '08

02 Dec '08

Cleaning up lava code and unsent messages. Hi all, This was an after thought from my previous post. It deserved its own topic. Lava code is code left over from historical times which has no use in the current image and yet no one is willing to take responsiblity for removing it. For the record squeak has historically had about one sixth of its messages as unsent methods. Some of which is lava code others of which are examples, probes, utilities and tests. It would be nice to clean things up so there are no unsent messages. This could be done simply by creating a (pseudo-recursive) message #legitamatelyUnsentMethods (one method say for each class.) That sends for any legitimate examples, etc. Then anything that shows up as unsent would be illegitamate and removeable. >From time to time you would look at the implementors of the legitamatelyUnsentMethods to clean out what no longer belongs. a legitamatelyUnsentMethods method would be packagable if care were take that it mentions only the unsent methods of that package. My proposal is that package maintainers should take the responsibility for doing this in their own packages and the release team should reject any code that contains unsent messages. An Sunit test could be provided to check. I am also hoping to recruit those who would be willing to sort out the unsent messages in core packages and either write legitamatelyUnsentMethods methods for them or flag them as lava code for removal. It is a good way to gain an insight into a lot of squeak code while helping the community. If this task appeals to you please start it by planting a seed on mantis.

[ANN] Euro 2008 Betting! 24 hours left!
by Göran Krampe 10 Nov '08

10 Nov '08

Hi folks! (This is a reminder - perhaps folks missed my previous post so this time I added "[ANN]" - almost noone from the Squeak community have joined up and previous years quite a lot of people did.) 2 years has passed and it is time to go crazy over soccer again! The european championship is about to start in exactly 24 hours and the little betting site I built 6 years ago (in Squeak3.9/HttpView2) is once again up and running! So drop by, place the bets and join up to see how it goes. No official prizes :) are set - but who knows. IMPORTANT: You got 24 hours to bet until the group play betting game closes! There are two other betting games though that are continuous so you can join later. http://em2008.krampe.se/eng regards, Göran PS. Will post a followup later on describing how we used the translation mechanism in Squeak to make the site in both english and swedish.

I've been needing to use spoon for my research project this summer, and now that the board has (finally) officially decided to base Squeak 4 on spoon, can I expect that there will be a downloadable spoon soon? as in, 2 weeks? -- Matthew Fulmer -- http://mtfulmer.wordpress.com/

23 Oct '08

I already created a bug report for this, Andreas may be able to tell you more: http://bugs.squeak.org/view.php?id=6980 As a workaround you can can use FFI-Kernel-ar6.mcz instead of FFI-Kernel-ar-8.mcz.

[ANN][Squeak-dev Images] September 2008 versions
by Damien Cassou 11 Oct '08

11 Oct '08

Hi, I've just uploaded new squeak-dev and squeak-web images based on Squeak3.9.1-7075, Squeak3.10.2-7179 and Pharo0.1-10062. More information and download: http://damien.cassou.free.fr/squeak-dev.html Pharo-based images can be downloaded at: http://code.google.com/p/pharo/wiki/Downloads?tm=2 New: download statistics at http://damiencassou.dabbledb.com/publish/dev-imagesdownloads Changes in this version: --------------------------- - Pharo images are based on version 10062. - Rio has been removed because its dependencies were getting bigger and bigger. I hope that will be fixed soon for a reintegration. - Algernon is included in all images now (Shift+enter to launch it) and is linked to OB (thanks to OB-Algernon) - Like every month, David Röthlisberger fixed a lot of issues in OB-Enhancement - Refactorings now have the possibility to rerun rules (thanks to Lukas Renggli) - OB-Tools has been temporarily removed. I would like to put it back as soon as possible because I think these tools are much better and extensible than what exists currently. Please help Lukas and implement the few missing features (like http://bugs.squeak.org/view.php?id=7164 and http://bugs.squeak.org/view.php?id=7148) I tried to integrate UI-Enhancements in all images but it failed. Probably due to a difference between 3.9 and 3.10.
