Nokia N810 as a Squeak PDA?
by Jim Rosenberg 21 Dec '07

21 Dec '07

Has anyone out there actually had their hands on a Nokia N810 running Squeak? I'm concerned about keyboard issues. According to one review I read, several special characters are not on the keyboard, and to get them you have to pick from some kind of screen gadget. Sounds like some kind of GTK applet that might not work in Squeak. How is the N810 keyboard from Squeak? I've been using Palm for many years, and all I use is memos and phone book entries. I'm not syncing with anything except the (yucky!) Palm desktop app. It wouldn't be hard to stitch together some off-the-shelf morphs to give me what I need in Squeak. One other concern I have outside of Squeak is that it seems to be not so straightforward to load apps for older versions of the Nokia internet tablets on the new OS. This is a pain! A body can get awfully used to the idea that all it takes to install something is ./configure, make, make install. Learning maemo just to port old apps myself seems like more of a project that I want for this device ... -Thanks, Jim

Which image where used to fetch the author initials ?
by Hilaire Fernandes 20 Dec '07

20 Dec '07

I need to know to which image the Andrew Black script was applied http://wiki.squeak.org/squeak/uploads/6016/MethodAuthorship-apb.mcz I was not able to find information regarding that point. It does not work with image 3.8 basic. It works with image 3.8 full but it gives additional authors. Nevertheless, it looks wiser we apply this script to image 3.9 or even better, image 3.10 or Pavel minimal kernel. What do you think Edgar, Pavel about that? In the wiki I have added references to related resources and informations http://wiki.squeak.org/squeak/6016 Hilaire

3.9 vs. 3.10 : Closures, fixTemps
by itsme213 20 Dec '07

20 Dec '07

Do block closures work right in 3.9? 3.10? I am struggling with local variables used across nested blocks (Magma #commit: within Seaside #callback: or Scriptaculous #triggerInPlaceEditor etc.) and am finding it quite frustrating. I had some #fixTemps but am totally guessing at when and why to use it. Thanks - Sophie

My experiences in downloading Squeak (How about a sources integrity check?)

My experiences in downloading Squeak (How about a sources integrity check?) Hi Hans-Martin, Hmmm. *** >To check, see whether your file has a size of exactly 17584742 bytes. If >it does not, it is broken. *** It seems to me this would make a pretty good sunit integrity check. Would you be willing/interested in following thru by making it one and putting it on Mantis? Yours in service and curiosity, --Jerome Peace ____________________________________________________________________________________ Never miss a thing.

Mac Squeak Crash - 6750stringAndCharFixes
by Tim Johnson 20 Dec '07

20 Dec '07

Hi all, I am on an Intel Mac running OS 10.4.10 with Mac VM 3.8.18beta1U. If I download the stock 3.8-6667 and go through with the updates, I can get to 3.8.2 until it hits the update called "6750stringAndCharFixes-mir..." at which point the whole thing locks up. If I let it sit, eventually it crashes with an out of memory error similar to the following: -----] snip [----- out of memory 874203632 String class>new: 874203540 String class>new: 874203448 CompiledMethod>defaultSelector 874203356 [] in Behavior>selectorAtMethod:setClass: 874203264 MethodDictionary>keyAtIdentityValue:ifAbsent: 874203172 Behavior>selectorAtMethod:setClass: 874203080 [] in Behavior>selectorAtMethod:setClass: 874202988 MethodDictionary>keyAtIdentityValue:ifAbsent: 874202896 Behavior>selectorAtMethod:setClass: 874202804 [] in Behavior>selectorAtMethod:setClass: 874202712 MethodDictionary>keyAtIdentityValue:ifAbsent: 874202620 Behavior>selectorAtMethod:setClass: 874202528 [] in Behavior>selectorAtMethod:setClass: 874202436 MethodDictionary>keyAtIdentityValue:ifAbsent: 874202344 Behavior>selectorAtMethod:setClass: 874202252 [] in Behavior>selectorAtMethod:setClass: 874202068 MethodDictionary>keyAtIdentityValue:ifAbsent: 874201884 Behavior>selectorAtMethod:setClass: 874201792 ContextPart>printOn: 874201564 MethodContext>printOn: 874201380 [] in Object>printStringLimitedTo: 874201472 SequenceableCollection class>streamContents:limitedTo: 874201288 Object>printStringLimitedTo: 874201196 Object>printString 874200920 MethodContext>printString 874201076 [] in Debugger>newStack: 874200828 OrderedCollection>collect: 874200736 Debugger>newStack: 874200644 Debugger>process:controller:context:isolationHead: 874199948 Debugger>process:controller:context: 874200040 [] in Debugger class>openOn:context:label:contents:fullView: 874199824 BlockContext>on:do: 874199480 [] in Debugger class>openOn:context:label:contents:fullView: 874199732 [] in BlockContext>newProcess -----] snip [----- I can totally reproduce this error every single time.

Appearance>Prefs>Help walkback & fix
by Amos 20 Dec '07

20 Dec '07

Clicking on the little "Help!" Button in World > Appearance > Preferences causes a walkback (subscript out of bounds: 0), in at least 3.7 to 3.10. I've reported the issue in Mantis (issue 6816), along with a fix and some badly needed refactoring ;-) Cheers, Amos

Frozen image
by Amos 20 Dec '07

20 Dec '07

Hi All, A couple of hours ago, I tried loading the FreeType Plus fonts via the Package Browser into my web dev image. It took a while, so I did something else and when I came back to take a look maybe 20 minutes later, it was still sitting there with an unfinished progress bar. So I figured it had hung itself and closed the image without saving (the image was still responding). Now when I start the image again, I get a frozen window that won't refresh (it displays whatever was behind it initially, or just black when it's minimised and restored). If I hit the close button on the window, Squeak happily asks me if I want to exit without saving, so I'm assuming that part of it is still running. Is that a "common" problem? Is there any way I can break in and stop whatever it's doing that freezes it up? I've tried Ctrl+B and Ctrl+Y (common mappings in VisualWorks), but can't seem to do anything; clicking any mouse button does nothing. There are quite a few things I've worked on recently that I'd like to save the image if possible, hopefully without having to manually go through the changes file. Any hints how I can achieve that would be greatly appreciated. Cheers, Amos

My experiences in downloading Squeak
by Squeaker 19 Dec '07

19 Dec '07

Greetings, I have been in a bit of a black hole over the past few days in attempting to get a version of Squeak 3.9 downloaded. I thought it may be helpful to list what I did so here goes: 1. Downloaded Squeak 3.9 (web) from here: http://squeak.ofset.org/squeak-web/ 2. Did the following test on the downloaded image: "1 break". What I was expecting when I did this is a Debugger but instead I got a "Syntax Error" window with a bunch of meaningless text in the window (at least to me it was meaningless). 3. Downloaded Squeak 3.9 (dev) from here: http://squeak.ofset.org/squeak-dev/ 4. Execute "1 break" and got the same "Syntax Error" window. 5. Downloaded Squeak 3.9 from here: http://www.squeak.org/Download 6. Execute : "1 break" and I got the normal debugger that I expected. What I conclude from this is that there may be something wrong with the download images at step 1 and 3 above. My goal was to have an image with Squeak and Seaside and that is what I think the link at steps 1 and step 3 offers but I suspect something is not right - at least it did not work for me - and I can reproduce the behaviour. Eventually I downloaded the "One Click" image from here http://www.seaside.st/download/squeak and everything works as I expected. If there is something wrong with the images at http://squeak.ofset.org/squeak-web/ I hope that it can be fixed because an image with seaside, pier and magritte is exactly what I was looking for. Cheers, Frank

[ANN] LevelPlayingField
by Keith Hodges 19 Dec '07

19 Dec '07

Hello All, In order to write/test packages in various squeak image versions, it would be very helpful if there were some (more) commonality between them in terms of the installation tools that they support. Introducing.... "Level Playing Field" LevelPlayingField is a script (LPF.st) which can be fed to 3.7, 3.8, 3.8.1, 3.8.2, 3.9, 3.10 etc etc in order to get a basic level of common functionality. This script hands off to scripts hosted at http://installer.pbwiki.com/ which are crafted specifically for each version of squeak. Here is an example of how you use it from a command line prompt... *#> squeak Squeak3.7-5989-basic.image http://installer.pbwiki.com/f/LPF.st Installer +debug user=kph do=Tidy;Update;MagmaSeaside SmalltalkImage save=MS.image +quit * This performs the following... 1. Load squeak with the given image, run the LevelPlayingField script LPF.st 2. Control is passed to scripts at http://installer.pbwiki.com/LevelPlayingField Installer, Monticello1.5, MonticelloConfigurations and Launcher are loaded, control passes to Launcher to handle further command line parameters. 3. Command line paramter 3, "Installer" passes control back to Installer. 4. Debug mode is enabled. 5. User initials are set to 'kph' (for example) 6. Control is passed to scripts at http://installer.pbwiki.com/Tidy where All windows are closed and the Mouse Logo is removed (sorry) 7. The script "Update" loads nominated bug fixes and package updates. 8. The script "MagmaSeaside" is ficticious right now... but it would install Magma and Seaside. 9. Control passes to SmalltalkImage 10. The image is saved under the name MS.image 11. Quit! If you wish to use installer.pwiki.com for your build scripts, you will need to guess the password... the clue is ... "what noise does a mouse make". I would like to open up installer.pbwiki.com to others who use different images in order to fine tune them. For example I cant get the 3.9 Kernel Image to work on my Mac, so we need a kernelImage expert to fill in the details. I have defined a series of scripts, in addition to "Tidy" we also have a more aggressive option, "Clean" for removing "Stuff", these two could use filling in by folks who are more expert at removing stuff than I. Finally there is a slot "Update" for Bug Fixes, and Package Updates for images... Fine tuning this "Level Playing Field" will need to be something undertaken by the community, I propose, if no one objects that the packages(a)lists.squeakfoundation.org mailing list be used for this purpose. Also if you want to discuss the possibilities at any point I am available in irc #squeak most days. best regards Keith
