Encodings/allowed characters in methods/categories/protocols
by Johan Björk 26 Apr '08

26 Apr '08

Hi everyone, This is my first post to this list, I apologize if my question is too basic for this list. I've been working on a remote-filesystem to display the sourcecode/object hierarchy of the squeak smalltalk image in a "normal" unix filesystem. (Using FUSE) I initially followed this resource http://www.mucow.com/squeak-qref.html , under Symbols, but ended up having to add more checking to my regexps. (It states that if it's a special characters, it is either 1 or 2 of them, however, in Integer, there is a method called '\\\' What is valid for protocols/categories? Doing some testing on the FS, we also encountered method sourcecode with strange encodings (ie, WideStrings used to store the sourcecode (JapaneseEnvironment / flapTabTextFor:in: for example), and also some method names that has special characters, ie, in the squeak-web image, there is a method called "göran" (Installer-Core/Installer/instanciation-abbreviated/göran ) Anyone know of any resource that outlines what encoding is used and what characters are allowed for Symbols? (I guess that's what it really boils down to?) Thanks in advance -Johan

Update Stream Gone? Replaced with Sapphire? What?
by Matthew Fulmer 25 Apr '08

25 Apr '08

Someone erased the contents of http://ftp.squeak.org/updates/updates.list and replaced it with something Sapphire-related. That is just wrong. The update stream needs to be preserved. -- Matthew Fulmer -- http://mtfulmer.wordpress.com/

Both. I'm trying to implement an image reader/writer hence I need to no the exact layout of the objects in the image and the form of the image itself.

Name that package
by Nick Brown 25 Apr '08

25 Apr '08

Hello folks. First post by me here in a good few years. I saw a mention here a few weeks or months ago of a new package which appeared to be an alternative to using FileDirectory and DirectoryEntry classes to look at the contents of folders on disk. ISTR an example which allowed folders to be searched recursively. Of course, now I've got some time to play with it, I can't remember what the dratted thing is called. I've looked through all the [ann] posts back to the start of the year, and of course searching for words like 'file', 'directory' and so on only turns up a million or so messages. Also had a look on SqueakMap and SqueakSource, in case anything jogged my memory, but no luck. Can anyone remind me of the name of the package, or better yet post a link? Thanks muchly, Nick

Input on class design for someone new to squeak
by Danny Chan 25 Apr '08

25 Apr '08

Hi! Lately I have been playing with approaches to implement multi dimensional arrays in squeak with functionality similar to python's numpy library. The structure I've come up with has a main array class with instance variables pointing to a ByteArray and an array type object. Whenever a message is sent to an array object, it is dispatched to the array type object which in turn will then choose a concrete implementation from a plugin. The code in the plugin is automatically generated from definitions contained in the various array type classes. For an accessor like at: for example I have a concrete implementation as Slang plugin for each data type that casts the ByteArray data to a pointer of the required type. So I have a structure looking like this: class ivars SqArray buffer, arrayType SqArrayType - SqArrayInt8 - SqArrayInt16 - SqArrayFloat32 ..... SqArrayPlugin -> concrete implementations Is this a sensible design for doing something like this in Smalltalk? Am I abusing the Squeak plugin mechanism very badly? And finally, does something better already exist? Any input and constructive criticism is very much appreciated, Danny

FISL 10.0 will include a 3-day smalltalk mini-conference!
by merlyn＠stonehenge.com 24 Apr '08

24 Apr '08

>From my blog at http://methodsandmessages.vox.com/library/post/smalltalk-at-fisl-now-and-fo… But the biggest news is that based on the preliminary interest in Seaside because of my talk, the FISL conference organizers offered an entire room for next years conference (the full three days with 12 hours per day), as well as four or five main-track hour talks, if I could help organize the subconference details! This is quite a gift, because it will mean that we can expose the 7000 conference attendees to a variety of Smalltalk programs, without paying for rooms or badging or promotion. The conference asked if I could get some corporate sponsors on board, and I immediately fired off email to James at Cincom and Monty at GemStone, and thank goodness they read email on Saturday, because they offered their support quickly. Of course, we have many details to work out, but everyone agrees that we will move forward! -- Randal L.

to be deployed Epaati version is out!
by Ties Stuij 24 Apr '08

24 Apr '08

Well, it took us at OLE Nepal a whole lot of sweat and especially tears, but finally, after half a year of hard work, we finished the first build that is actually going to be used by actual Nepali kids, in an actual classroom setting. This build, version 10, sports a whopping 47 activities, which is why it's 105 mb in size. The loading time of individual activities has also diminished by quite a bit (sometimes loading is 3 to 4 times as fast), and memory consumption has been greatly reduced. And this is just the beginning, because there are a great many much of activities to be made in the future. get it here: http://dev.laptop.org/pub/epaati/Epaati-10.xo For you who never heard about Epaati: it's an activity suite (for now) geared towards grades 2 and 6 (roughly 8 respectively 12 year old kids) of the Nepali school system coinciding, not coincidentally, with the classes which are the focus of our pilot projects. The subjects covered are Maths and English, and we follow the official Nepali curriculum so our activities can be integrated seamlessly in regular sessions. Which is not to say of course they can not be used by others. Especially the English activities can be used practically as is by children with another mother tongue, save for the help text. Also converting the maths activities should be not a big deal, since not a lot of Nepali specific text is used, but there are some brambles to be fished out of the porridge, before we have a smooth mechanism for translation. Anyways, have fun with the new and old activities, /Ties

Re: [Webteam] squeak zip-freezes

Staffan, I don't know the problem, but you could ask on the squeak-dev or beginners mailing list. This might be a universal problem so I will copy the squeak-dev mailing list to see if anyone has an answer (if anyone has an answer for Staffan, could you also copy him directly) A similar question was raised on the beginner's mailing list so you're not alone. Here's the conversation with a possible work-around: ================================ I don't have any Vista experience, but here's a shot in the dark, courtesy of google: http://www.howtogeek.com/howto/windows-vista/prevent-explorer-from-freezing… Or, if you have had good past experience with .zip files using Winzip+Vista, maybe try downloading a different version of squeak from http://ftp.squeak.org, like 3.9 perhaps, and see if it unzips correctly. ----- Original Message ---- From: globalrev <skanemupp(a)yahoo.se> To: beginners(a)lists.squeakfoundation.org Sent: Wednesday, April 23, 2008 1:52:23 PM Subject: [Newbies] Squeak-extract zip freezes Vista? i am trying to install Squeak, downloaded it from : http://www.squeak.org/ when trying to unzip winzip stops responding and i have to close it. why is this? what can i do insetad? ============================ On Wed, Apr 23, 2008 at 10:02 AM, Ragga Dajj <skanemupp(a)yahoo.se> wrote: > hi > > i downloaded the squeak-zip to windows vista and when i try to unzip it > itjust freezes. > > what could be the problem? > > staffan > > > ________________________________ > Går det långsamt?
