www.squeak.org finally updated
by goran＠krampe.se 09 Jul '05

09 Jul '05

Hi folks! Just edited www.squeak.org a bit (fixed some stuff that simply is outdated) and most importantly went over the download page with the 3.8 release and some new links (Master unix and win32 site for example). Also, Tim, the first link on your master site below is barfed: http://www.rowledge.org/tim/squeak/RISCOSSqueak.html People, please look over the download page and report if there are any things that are wrong. Also modified the links so that the primary download URLs are "ftp://ftp.squeak.org/...". And yeah, if anyone wants to set up a mirror then check out: ftp://ftp.squeak.org/MIRRORING.txt ..and report back if you actually do set one up (so that we can link to it). regards, Göran

[ANN] Monticello Package Browser v 0.5
by Alexandre Bergel 09 Jul '05

09 Jul '05

Hello, I finally found some time to work on the package browser. Screenshots and download are available on http://smallwiki.unibe.ch/monticellopackagebrowser/ Here is a small report for this version: What is new in this version: --------------------------- -A comment can be assigned to a package (of course, they are saved and retrieved), however the GUI is not well supported. -Running test unit classes (it is not related to packages, but this is quite useful). Tentative Roadmap: ----------------- 0.6 - GUI Prerequisite support for prerequisite packages 0.7 - Optimizations (Omnibrowser is a a bit slow, I need to dive into it) 0.8 - Support for package refactorings (fusion of two packages, fading a package into the system, divide a package into smaller pieces, ...) 0.9 - Binary support for packages. 1.0 - Squeak 4.0 Purpose of the project: ----------------------- Having one self contain package related tool -Packages are First class Entities, it make simpler operations such as renaming, refactoring (fusion of two packages), analysis, ... -Package related Information like class extension are quickly rendered. You can browse extension of the Package without waiting for dozen of seconds. Just to browse extension of the System package, about 40 seconds on my computer to find out that System extends Object, Behavior and ClassDescription with 5 methods. With the MonticelloPackageBrowser, it is instantaneous. -Packages are commented -Compatible with the PackageInfo naming convention (*mypackage-), therefore your project will be still loadable in a old image. -People who does not care about modules at all (e.g., if they prefer ChangeSets) will not notice any difference. -Load, save, repository management, get package information (e.g., class extensions) from within a single tool. Any feedback appreciated... Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.iam.unibe.ch/~bergel ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Blocking morph action menus for code browsers
by stéphane ducasse 09 Jul '05

09 Jul '05

hi while programming I noticed that most of the time, I bring the wrong menu on the browser always the grab...Morph related instead of the action ones. Does one of you have a changes so that I could either avoid the morph one or bring the action one instead? Stef

New book finally out...
by Stéphane Ducasse 09 Jul '05

09 Jul '05

Hi Finally the book is out.... I still does not have it in my hands but soon :). Some of you already got it. Have fun Stef Here is the previous announce I sent around. Hi If you are a parent, an educator or a programmer having kids this is for you! After 4 years of work, my new book "Squeak: Learn programming with Robots" will be out soon http://smallwiki.unibe.ch/botsinc/ http://www.amazon.com/exec/obidos/tg/detail/-/1590594916/ qid=1117218524/sr=1-1/ref=sr_1_1/002-5642974-5143261?v=glance&s=books With Bots Inc you will learn how to program robots in an interactive environment. Bots Inc proposes three teaching approaches: direct command of robots, scripting robots and programming robots. The book contains 24 chapters going step by step over topics with a lot of examples. Bots Inc is fun but it is not a toy, it teaches you 100% real programming in Smalltalk: a pure object-oriented programming language that has been copied by Java. Bots Inc is built on top of the rich open-source multimedia Squeak environment that you can also discover. My goal is to explain key elementary programming concepts (such as loops, abstraction, composition, and conditionals) to novices of all ages. I believe that learning by experimenting and solving problems with fun is central to human knowledge acquisition. Therefore, I have presented programming concepts through simple but not trivial problems such as drawing golden rectangles or simulating animal behavior. The ideal reader I have in mind is an individual who wants to have fun programming. This person may be a teenager or an adult, a schoolteacher, or somebody teaching programming to children in some other organization. Such an individual does not have to be fluent in programming in any language. As a father of two young boys I also wrote this book for all the parents that want to have fun programming with their kids in a powerful interactive environment. Programming in Smalltalk is an interactive, fun but deep experience. Testimonies "I am using the version of the book on your web site to teach my oldest daughter Becca some programming. She absolutely loves it. We are doing the Bot graphics right. My other kids are showing interest as well. My Fall semester schedule leaves me with almost no time free but in the Spring I hope to bring Squeak and your book to our elementary school's "gifted" program." C. David Shaffer "I'm using the Bot Lab environment for three years and found it really valuable in teaching computer science concepts for a young audience (and even less young !). The bots commanded through balloon (as in comic strips) is a very nice introduction for young children, and when this aspect is well understood, you can use the Bot Workspace to teach the notion of script, a first step in programming languages. The Micro Browser allows children to add new behavior for their bots, and have fun with their creation. This three-layers tool - Balloon, Micro Workspace, Micro Browser - offers to the teacher a fun way to introduce gently the basis of object-oriented programming concepts. With Bots Inc, learning is playing ! ;-)" Samir Saidani - University of Caen - France "I recently started a course with 7th-graders (age about 13 years) with Stephane's book --- they love it. They all know about syntactic issues from maths --- in a way they know that an expression in a formal language must be well formed. So they easily grasp the fact such as "there must be a colon after the message-name if an argument follows". Of cause they don't really read the error-messages, they just see "there must be some error" and they remember the simple rules. Don't underestimate Smalltalk --- it's easy understandable because it has a simple and straight-forward design." Klaus Fuller - Germany Have fun... Stef 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

Screenshots for new web site
by Thomas A Petersen 08 Jul '05

08 Jul '05

Hello again, Here's a hopefully useful connectors / diagram browser centric screen shot. Once again it's a 32 bit screen smashed down to 256 colors for web friendliness. Connectors Rocks! I use it to diagram relationships in that lesser interpreted scitzofrenic language that has spread too far. I've also coaxed it into doing some database relationship diagrams Connectors is far less restrictive than Erwin. Connectors is also a useful tool to graph user interface trees; this screen goes to that one, this link evokes that menu, and so on. If nothing else, Ned and/or Hernan might want to snitch this to show off Connectors and the diagram browser. Enjoy, tap Enclosure: 08_BasicDiagram.gif (See attached file: 08_BasicDiagram.gif)

Jason, et. al, How about this one. I actually run in 32 bit color. I have cut the color count on this screen shot down to make it more web friendly. It shows of Shout and how you can make Squeak easier to read. This was taken from a Win XP Dell system. Enjoy, tap Enclosure: 06_Screen.gif (See attached file: 06_Screen.gif)

screenshots for new website
by Jason Rogers 08 Jul '05

08 Jul '05

Here's another bug in your ears... Croquet folks: can I use any of the screenshots on your site? SmallLand folks: any shots? How about SqueakLand? I don't have everything running on my box, so I can't take screenshots of it all. Do I have any volunteers? How about some up-to-date Mac OS/Windows/Acorn/BeOS/iPaq/Zaurus/etc. shots? Come on folks, you all must have some stuff that you want shown. -- Jason Rogers "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
