It does *not* work for me either. My setup is Pharo #14140, on Ubuntu Linux 32bits with a US International keyboard layout. When I press `Alt+shift+(' I get a parenthesis. However, when I press "Alt+[" I get the selected output between square brackets (what I expected). Would it be possible that the Shift key (required to press $(, $), and $") deactivates the smart-character feature? With CogVM as follows: $ CogVM -version 3.9-7 #1 Mon Aug 22 17:40:54 CEST 2011 gcc 4.1.2 Croquet Closure Cog VM [CoInterpreter VMMaker-oscog-IgorStasenko.108] Linux pharo-build.lille.inria.fr 2.6.18-194.26.1.el5xen #1 SMP Tue Nov 9 14:13:46 EST 2010 i686 i686 i386 GNU/Linux -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."

[Pharo-project] Smalltalks 2011: Call for Submission/Participacion

by Fundacion FAST

Sorry for multiple copies Following you have the Spanish version of the Smalltalks 2011 Call for Submission/Participation ======== ENGLISH The FundaciÃ³n Argentina de Smalltalk (FAST, http://www.fast.org.ar) invites you to the 5th Argentine Smalltalk Conference, to be held on November 3, 4 and 5, 2011 at the Quilmes University located in Buenos Aires. Everyone, including teachers, students, researchers, developers and entrepreneurs, are welcome as speakers or attendees. Registration is free and now open at http://www.fast.org.ar/smalltalks2011 The goal of the Conference is to strengthen the bonds between the Argentine and the international Smalltalk community through the exchange of works, experiences and anecdotes connected with this technology and related matters. As in the previous editions, renowned members of the international Smalltalk community will visit us, and like last year we will have a Research Session with publications reviewed by an international committee. Also, the traditional Industry Track will be available for those who prefer a more practical environment. You can submit papers or talks now through our website at http://www.fast.org.ar/smalltalks2011/technical-session Finally, a Pharo Sprint will be held prior to the conference for those willing to help the community coding, and two seminars will take place for those who want to get acquainted with or learn more about Smalltalk. For more information go to http://www.fast.org.ar/smalltalks2011/events For any questions please contact us at info(a)fast.org.ar.
