[GOODIE] MultiSelectionInLists
by alain.plantec＠univ-brest.fr 30 Mar '05

30 Mar '05

from preamble: "Change Set: MultiSelectionInLists Date: 30 March 2005 Author: Alain Plantec Implements multi-selection for ScrollPanes (PluggableListMorph in Browser and SimpleHierarchicalMorph in Tamaris for example). It allow handling of (a priori) an unlimited number of sublists. Each sublist is marked with an 'emphasis' (a ListItemMorphEmphasisModel) which is a textColor, a font and an emphasis code. A sublist emphasis is given with an emphasis rule (a ListItemEmphasisRule). A particular emphasis rule gives events condition and triggered action on list (list view update). Two instance variable have been added to ScrollPane : eventRulesHandler emphasisIndex. - eventRulesHandler is a ListEventRulesHandler. All ListItemEmphasisRule are stored and triggered from it. emphasisIndex is a ListItemMorphEmphasisIndex. All list item emphasing are kept and get from it. This cs implements two useful sublist kinds: a bold blue and a bold red one. bold blue is for drag and drop, bold red is for item removal. How to test it: First, close all your browsers. install the cs from a file list. now you have to close your file list which is no more useable. Bold blue list test : for drag and drop Open a browser. In the selector list, you can collect a blue sublist with shift+left button (red button?). Now you can drag blue selection (all selectors in one drag) and drop it into another category for example. Drag and drop is also working on class list : you can drag and drop a list of classes from one system category to another for example. Bold red list test : for item removing In order to insert an item in a red sublist : capslock and cmd-x (it's cmd-X). Item under mouse pointer is inserted in a red sublist. Then with cmd-x, all red sublist items will be removed (after a confirmation). It works with selectors and classes list. Dependency : 'Hierarchy List Morph - Navigation' should be installed before"!

[ENH] commentsIn
by gaelli＠emergent.de 29 Mar '05

29 Mar '05

from preamble: "Change Set: commentsIn Date: 28 March 2005 Author: Markus Gaelli Introduces the ability to read all comments of a method and not only the first one. Not smart enough to bypass quotes in string constants, but does map doubled quote into a single quote. "!

New Squeak Management Structure
by John Pfersich 29 Mar '05

29 Mar '05

I haven't been paying any attention for a while to the new structure that Goran has been promoting. I find that lately its been really hard to follow the thread because the subjects do not reflect the topic being discussed. Is there a place that it's down on paper? I had signed up for the maintenance of the Network section under Task Force November Revolution (TFNR). Will that change? I'm liking this over BFAV just because it's easier to see the Network stuff that I'm trying to maintain. I do have a question about how the stuff gets harvested (or whatever the term is now). How does that happen?

Is Smalltalk powerful? Prove it!
by Noury Bouraqadi 29 Mar '05

29 Mar '05

You're sure that Smalltalk is powerful. You can prove it by means of some interesting application, some useful tool or any other piece of code. Apply for the ESUG Innovation Technology Awards, and come share your experience with other Smalltalk enthusiastics. All you'll have to do is sending a short summary about your software and come demonstrate it to ESUG attendees.

Class Instance variables
by merlyn＠stonehenge.com 29 Mar '05

29 Mar '05

In the article <http://groups-beta.google.com/group/comp.lang.smalltalk/msg/63af6a2749af4a17>, there's a link to <http://www.scottishdevelopers.com/downloads/articles/AWeeBletherAboutSmallt…>, which claims that Squeak doesn't have Class Instance variables. I offered a rebuttal (which hasn't made it to googlenews yet) that clearly stated that not only does Squeak *have* Class Instance variables, I was able to determine that there were 22 instances of such in my current image, with the expression: (Metaclass allInstances select: [:m | m instanceVariables size > 0]) size And I had no clue how to do that before I spent about 8 minutes browsing the image. But there are the results. :) I even browsed a few of the classes just to see how they were used. Nothing significant, but nice to know they're there, and that the original PDF was wrong. Smalltalk, for being reflexively introspective, is unbeatable. -- Randal L.

RE: Will Wright's Spore
by Darius 28 Mar '05

28 Mar '05

Better link: http://www.gamasutra.com/gdc2005/features/20050315/postcard-diamante.htm Will Wright's Spore is a bit similar to Croquet on these points: 1. Multi-user, synchronized, 3D environment - scaleable by both number of users and zooming from the macro to the micro in the 3D space 2. Algorithm created content (optional in Croquet) 3. User created content is the best content because it encourages "ownership" Spore advantages over Croquet: 1. Everything is algorithm generated so its fast, compact, easy to distribute. 2. Ease of 3D content creation due to predefined pallet of construction resources from which to choose 3. Physics is automatic and inter-object physical interaction behavior is extrapolated at runtime 4. Hard to reverse engineer, so easier to protect Intellectual Property if you have any 5. Efficient generation/memory-storage of textures 6. All 3D content exists in one single universe, so all content can be located by a single 3D position in the universe for it 7. Articulated avatars with preprogrammed, realistic motion & behavior 8. Hard for the user to crash the system 9. Less need for security to insulate users' behavior from each other Croquet advantages over Spore: 1. Not all content can be expressed by algorithms, especially in education, where the domain to be learned has already been expressed in other multimedia 2. Users can create their own programming logic/behavior as well as their own content 3. Lots of new non-algorithmic content can be created 4. Open source 5. Easier to enhance with add-on extensions which are automatically distributed 6. Hard to derive content from algorithms, so hybrid approach helps in transition 7. Can easily record and play back the user stories in dynamic or other multimedia 8. Easy to reverse engineer, so easier to enhance or build the next big thing 9. Multiple user-created worlds can exist separate from each other, so easier to focus on specific communication activity or learning activity, and easier to create/duplicate a world & its content 10. Can search content data for values, labels, or code used by the active content 11. Can represent the chemical tools of biological organisms as well as structural tools I'm sure others can think of more advantages and disadvantages.

Squeak People posting summary
by cg＠cdegroot.com 28 Mar '05

28 Mar '05

Below are the most recent 5 articles that were posted on Squeak People (http://people.squeakfoundation.org/). Apart from the articles, you will find people's diary entries there, and an overview of the Squeak community: who is doing what, people's "standing", etcetera. If you don't have an account, please join - we're interested in getting to know you better! This message is posted automatically every week by a dirty shell script. _________________________________________________________________ Date: 2005-02-20 21:46:55 Author: lexspoon Title: Squeak as a Commons Before we can organize Squeak, we must answer: "What is Squeak?" This article defines Squeak as a commons where many individual projects collaborate. The article sketches some of the subgroups using Squeak, and proposes an organizational structure based around giving representation to all of these subgroups. _________________________________________________________________ Date: 2005-01-27 15:49:25 Author: gokr Title: Taming the translation beast! Now - I have just started figuring out how to translate my [1]Homepage Builder application to english and of course ended up digging into the translation stuff. This is a short (well, kinda) report on what I found, how to use what we have, and what I think we need to fix. _________________________________________________________________ Date: 2005-01-10 04:23:15 Author: elvislives Title: squeak logo lookalike Hi, _________________________________________________________________ Date: 2004-12-30 16:37:02 Author: jj Title: Boosting Squeak: RockSolid images I have read the "rant" and "unrant" subject with a mix of uneasiness (embarrassment) and fear. The "Rant" thread began on the 15th of december 2004, and produced a lot of discussion. I will not summarize the thread, because a lot of people read it. Instead, I will go forward and try to find a pragmatic and constructive of helping the community (and yes, I am also very bold and handosome :) << ironic comment). _________________________________________________________________ Date: 2004-12-20 00:34:35 Author: cdegroot Title: Terminus is up'n'running Terminus, the little system I cobbled up to export Squeak People's account and web-of-trust information, is up and running. The first app is a [2]Wiki which uses Terminus to decide whether certain actions are possible.
