About "A Taste of Smalltalk"
by Stephane Ducasse 07 Oct '02

07 Oct '02

Hi archeologist and Smalltalk oldies freaks We with alex started to scan the book "A Taste of Smalltalk" (thanks Ted for the rights to do that). However, it takes me around 3 min per pages, so I would like to know if somebody want to do some postprocessing of the files to see if we can obtain a pdfs and at which quality. The images of the prefaces and the first chapters are available at: http://www.iam.unibe.ch/~ducasse/WebPages/FreeBooks.html Stef Dr. Stéphane DUCASSE (ducasse(a)iam.unibe.ch) http://www.iam.unibe.ch/~ducasse/ "if you knew today was your last day on earth, what would you do different? ... especially if, by doing something different, today might not be your last day on earth" Calvin&Hobbes

Enjoy. Let me know of problems, ideas and so forth. Lukas Renggli and Alexandre Bergel helped alot with this release (and I haven't merged all their work yet). If they keep interest, I'm betting we'll be seeing various interesting things happen.

Looking for nano-Self
by Stephane Ducasse 07 Oct '02

07 Oct '02

Hi I'm preparing some material for a lecture where I would like students (mostly non smalltalker and non-schemers) to build a minimal prototype-based language, a minimal class-based, mixin-based languages. I have already all the material for a reflective class-based language (but this will be too much). So I was wondering if you already play with the idea and how you were coding the prototype based language. In particular I would like to know what are the minimal methods and how you handle state.

A summary of a few recent projects
by danielv＠netvision.net.il 07 Oct '02

Or, for those who're maybe wondering "what's all that noise with SqueakMap, ModuleFiler, Dynamic menus and that Spaghetti thing?" Well, they're all basically projects geared to make Squeak more friendly to packages living outside the standard image, and the people that write them and use them. This is quite independent and complementary to having a modules system, and can help Squeak shrink. I'll explain SqueakMap first - People used to unix machines find it quite normal that they have to compile new packages for their computer. Windows users are quite used to popping a CD in, pressing next.next.next and having it appear, if they happen to have what's needed, and nothing gets fubared. Debian (a linux distribution) people bring up a dizzying menu with >8000 packages, select what they want, from a new kernel version, to a shoot-em-up to an astronomy package, ask for them to be installed, and drink coffee while everything is downloaded automatically from a central server, where everything is (more or less) up to date, including whatever libraries are needed, configured and installed. In none of the above systems do most users have the same precise applications installed... people can and do choose what tools and games they like to have available, and there's a standard, common way to realize their choice. SqueakMap makes Squeak a little like Debian. Open a Morphic package browser - you get an open list of packages, updateable on the web. As many as have a proper download Url, can be installed by select&click. So if you like Whisker or the Refactoring Browser, you can install it as easy as pie, without any sort of searching at all. If you're a new Squeaker, you can see what's available very easily, and try things out. If you're developing something neat and want to get feedback beyond the next few days after you announce it on the list, post a SqueakMap description, with a convinient download page, and you're set. If you want to try out SqueakMap, you should wait to Gorans next (6th) release, and use either his package browser, or my simpler, more limited one. If you want to try it NOW, use release 5, which works just fine but requires a little manual work to install - * unzip http://anakin.bluefish.se:8000/gohu/uploads/11/squeakmap-020924.zip * run sminstall-mini.st * unzip and filein http://anakin.bluefish.se:8000/gohu/uploads/11/SqueakMapFix-020924.cs.gz * SMSqueakMapBrowser open To use my package loader, also do * filein http://modules.squeakfoundation.org/People/dvf/Packages/SM-Loader.st * SMLoader open Either tool will display a list of packages. Pick one and see it's details, if it has a download url, you can download/install it with a couple of clicks. You're welcome to try it out. If you want to browse the web UI, go to http://marvin.bluefish.se:8000/sm. You can also register your own package there, it's just a form you need to fill out. The idea is to get SqueakMap + a simple package loader into 3.2, so people can then easily load anything they want. This mail is already too long. Next - DynamicOpenMenu, but that's tommorrow.

Squeak Server Pages
by Daniel Joyce 07 Oct '02

07 Oct '02

Heya, I just stumbled across the SPP stuff on the squeak swiki, the last update for it was 2.9 though. There is also another Squeak Template pages system, but it doesn't seem to be as clean or easy to use as SPP is. Supposedly, it's used for good chunks of Swiki.net Has it been ported forward to 3.2 yet? Is Stephen Pair still on this list? When I try and file it into a recent version, I get a traceback. -Daniel

You're right - SqueakMap is a catalog. It's purpose is to make package visible and easily installable. It doesn't explicitly manage conflicts or dependencies. There is a nice trick we could use to help with dependencies: upload a package that loads other packages, like this - packages _ {'Refactoring Browser'. 'SM Package Loader'} collect: [:packageName | SMSqueakMap default cardWithName: packageName]. packages do: [:package | (SMInstaller forPackage: package directory: package downloadUrl) install] Just put something like this in an .st.gz file somewhere on the web, register your package using the web form at http://marvin.bluefish.se:8000/sm/regpackage, including the download url, and that's it, anyone can now load all required components in proper order.

Refactoring Browser - new release, new home and other news.
by danielv＠netvision.net.il 07 Oct '02

07 Oct '02

The URL for the impatient - http://modules.squeakfoundation.org/People/dvf/Packages/Refactory.st The SqueakMap entry - http://marvin.bluefish.se:8000/sm/package/2b1e12d7-3d60-481d-975e-3eca5a ef50b9 To open it, RefactoringBrowser openBrowser. Welll, it's been a long time since I've released the RB, and the last release wasn't the most friendly out-of-box. A few reasons you will like this release - * Simplified install This release is a single 1MB .st file. Just download and filein. Or, if you have some SqueakMap based tool, like the SM Browser by Goran or my Package Loader, you can bring it up, pick the Refactoring Browser, choose to install, and you're done. * It works Tests are green, some basic sanity checking works on a clean 3.2 4956 image. Of course there are probably bugs hidden somewhere in there, but that I need you to help me with that. * Lint works again Thanks to Alexandre Bergel and Lukas Renggli, who fixed that and a few other issues in CS@ESUG, this year in Douai. More detailed version information is at the SqueakMap page. The release process changed quite a bit on the way to this release: I was very annoyed with maintaining the 15 (!) different files of code, by abusing changesets to keep the layers separate. Abuse your tools and you'll get sore thumbs. The world is consistent that way. Making a release was long, downloading and installing was annoying, testing it was hard and time consuming. So when things were broken, they didn't get fixed, which makes for very lousy maintenance. Using Avi Bryant's ModuleFiler, I am able to file out the related system categories and all their class extensions to the base image with one operation, creating one file. The normal system categories and method categories keep my layering information intact and more consistent than I could with changesets. Thanks to SqueakMap, it's now a snap to download, install and update new versions, and will soon even be easy to upload and publish new versions too. Easy management will make for less laborious releases, and hopefully better maintenance. So you're welcome to download, install and play with it, and please let me know of any trouble you encounter.

SqueakOS

How difficult would it be to turn Squeak into an OS? Has there been any discussion / papers about this that someone can point me to? Thanks, Derek Phasecraft: Smarter Web Development.
