[Etoys] Project file with massive Smalltalk source code
by Hilaire Fernandes 20 Sep '08

20 Sep '08

Hello all, I have been experimenting the reliability of project file (.pr) with DrGeo Smalltalk source code With the help of Bert I produced an .pr file containing in the default changeset the drgeo source. The project file is at http://download.gna.org/istoa/drgeo/DrGeoII.pr So far loading the .pr file in the default Etoys environment as provided by Squeakland is ok. Then experimenting and saving a Drgeo consutrction went fine, Etoys asked if the current change set modification should be saved as well. Responding yes, the project is saved just fine with the source code. Next when reloading the newly created project from an empty Etoys image produce an error about Syntax error: (See log file) But it looks like some portion of the DrGeo code was left over when resaving it. For example I have a fix Float>>arcTan2: in category *DrGeo-fixing And the syntax error appears in a method using it. Any ideas ? Hilaire -- http://blog.ofset.org/hilaire

[Etoys] Lisp50@OOPSLA -- Celebrating the 50th birthday of Lisp at OOPSLA 2008
by Robert Hirschfeld 18 Sep '08

18 Sep '08

Lisp50@OOPSLA ...celebrating the 50th birthday of Lisp at OOPSLA 2008 Monday, October 20, 2008 Nashville, Tennessee, USA co-located with OOPSLA 2008 participation is free for all OOPSLA participants registration for at least one conference day at OOPSLA is required URL: http:www.lisp50.org Feed: http://lisp50.blogspot.com Invited Speakers + William Clinger, Northeastern University, USA + Pascal Costanza, Vrije Universiteit Brussel, Belgium + Richard Gabriel, IBM Research, USA + Rich Hickey, Independent Consultant, USA + Alan Kay, Viewpoints Research Institute, USA + Fritz Kunze, USA + Ora Lassila, Nokia Research Center, USA + John McCarthy, USA + Kent Pitman, PTC, USA + Guy Steele, Sun Microsystems Laboratories, USA + Herbert Stoyan, University of Erlangen, Germany + Warren Teitelman, Google Inc., USA + JonL White, USA Titles, abstracts, biographies and schedule will be announced at the Lisp50 webpage and blog in the coming days and weeks. Abstract In October 1958, John McCarthy published one in a series of reports about his then ongoing effort for designing a new programming language that would be especially suited for achieving artificial intelligence. That report was the first one to use the name LISP for this new programming language. 50 years later, Lisp is still in use. This year we are celebrating Lisp's 50th birthday. OOPSLA 2008 is an excellent venue for such a celebration, because object-oriented programming benefited heavily from Lisp ideas and because OOPSLA 2008 takes place in October, exactly 50 years after the name Lisp has been used publicly for the first time. We will have talks by John McCarthy himself, and numerous other influential Lispers from the past five decades. We will also take a look at the next 50 years of Lisp. Organizers + Pascal Costanza, Vrije Universiteit Brussel, Belgium + Richard Gabriel, IBM Research, Hawthorne, NY, USA + Robert Hirschfeld, Hasso-Plattner-Institut, Potsdam, Germany + Guy Steele, Sun Microsystems Laboratories, Burlington, MA, USA Sponsored by ACM SIGPLAN Supported by + IBM Research + LispWorks Ltd + Franz Inc. + Clozure Associates -- Robert Hirschfeld hirschfeld(a)acm.org www.hirschfeld.org

[Etoys] Dropzones in the ScriptEditor
by karl ramberg 15 Sep '08

15 Sep '08

The script editor does a slide into position thing with dropped tiles., but it sometimes miss the drop location and that causes ugly artifacts and not so nice feel on a slow machine as the XO. The method in question allways adds the dropped tile to the right place but often calculates the end location of the animation wrong. Karl

[Etoys] Please visit the new Etoys website!
by Kim Rose 11 Sep '08

11 Sep '08

[Forwarding from the Squeakland list - please forgive the crossposting. Bert] Greetings! Many of you have started, or will shortly be starting, a new academic year at your school or University. We wish you a successful and fun- filled new school year! We have just launched our new Etoys web site to coincide with the new academic year. It is still found at "www.squeakland.org", but its design and content are all new. It features a brand-new version of Etoys for download, which we will announce in a separate message. We hope you'll find the new site simpler to navigate, more straightforward in sharing our message, and loaded with helpful content. New materials include complete video from the "Squeakers" DVD and a series of "screencast" lessons, thanks to Tim Falconer of Waveplace. You'll also find some new tutorials and a showcase of projects. Also on the site are web versions of over 50 "QuickGuides", created by Kathleen Harness of Illinois, which provide concise tutorials for many things about Etoys. Living versions of the QuickGuides can also be found "inboard" in the new Etoys application itself (click on the ? at the left edge of the tool-bar). The "showcase" section on the new site has very few projects on it at this point -- please share your projects to help populate this area! We intend the site to be a living, continuously-evolving resource, a showcase and clearinghouse for "all things about Etoys." Please help it evolve and grow. The site will be largely maintained and supported by volunteers, so we need your contributions as well as your suggestions. We will also be producing a quarterly newsletter that will be posted to the site (and sent to you via email if you choose to subscribe) so please share your experiences with us! Thanks to you all for your interest in this learning community. We look forward to exchanging ideas, projects, and more. regards, Kim Rose & the Etoys team

[Etoys] Possible to load/import project from file without going to World Menu?
by Milan Zimmermann 10 Sep '08

10 Sep '08

Hi, Today I realized that I do not know how to import a project from file without going to World Menu - or is hiding the filesystem as a way of sharing discouraged (not a bad thing but still surprised me). Thanks Milan PS: As a note, today I tested export/import via file using "hold down quit button + Save Project As" + load from world menu - that worked. Some forms of saving project gave error - reported on trac.

So please test this version and if you find severe bugs, please report them as soon as possible. Thanks! - Bert - (*) If you are interested in the changes, look for the %changelog sections here: http://etoys.laptop.org/srpm/etoys-3.0.2126-1.spec http://etoys.laptop.org/srpm/squeak-vm-3.10-3olpc10.spec

by Hilaire Fernandes 07 Sep '08

07 Sep '08

Hello, Are there any reason the pretty print and color when pretty printting options are off in the EToys image? It makes Smalltalk code more readable for all and for project using Smalltalk scripting like Dr. Geo Hilaire
