[BUG][FIX] In SqueakCore Workspace when you try to do some which sends toggleStyling raises DNU
by Edgar J. De Cleene 08 Dec '11

08 Dec '11

And the cause is toggleStyling shouldStyle := self shouldStyle not. " Ugly hack, to restyle our contents. " self codeTextMorph in: [ :codeTextMorph | codeTextMorph setText: codeTextMorph textMorph text asString asText ] StringHolder>#codeTextMorph was removed as part of services. So my idea is move to user edits category and put new versions of touched packages, what you think ? Edgar

by Stephan Eggermont 07 Dec '11

07 Dec '11

Call for Participation in the Smalltalk Devroom at FOSDEM 2012. "A devroom for the Pharo, Squeak, GST, Etoilé, Seaside, Moose Smalltalk projects. Smalltalk environments offer a very high development productivity, unmatched by their successors. Come do some pair programming with us and experience the advantages of a real OO environment." The meetup will take place Sunday, February 5, 2012, from 9AM until 5PM, room AW1.126. This room has 72 seats, a VGA video projector and wireless internet. More information will be available later. Proposals on content and format are welcome. People interested in running a session should announce that on the smalltalk-devroom mailing list, with the following information: - Their name - The project they are associated with - A short bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A abstract describing the session in further detail. - The desired length of the session. - The desired time slot in which they want to hold the session. Suggested values for the duration are 55min, 25min, 6m40 (Pecha Kucha). The desired time slot is meant to help you prevent conflicts with other dev rooms in which you might have a talk or your travel arrangements. The deadline for submissions is December 31, 23:00 GMT+1. Discussion takes place on the smalltalk-devroom(a)lists.fosdem.org mailing list. Please subscribe if you are interested: https://lists.fosdem.org/listinfo/smalltalk-devroom The local VUB/ULB Smalltalkers have been asked to organize a sprint/BSUG meeting on Saturday Februari 4.
