I wouldn't mind having that accessible via hotkey, and don't like how the default auto format formats blocks at times.

One solution to the problem of cosmetic changes showing as differences: Don't do it especially on others' code. If someone is changing functionality, they are welcome to reformat entire methods they change to their taste. Otherwise, I would (almost) never make cosmetic-only changes to other peoples code..

Framecap Plugin
by Ragnar Hojland Espinosa 31 Mar '06

31 Mar '06

Grab frames from a webcam. I pluginized (or should I say pluginised..:) the Framecap DLL that Jon posted a while ago; this means that, to use it, you will need Hewitt's Framecap exe running and the fgClient.dll in the squeak directory. Oh, and it's still slowish ... :) -- Ragnar

Dynamic Languages Symposium 2006 - Technical Papers (CfP)
by Robert Hirschfeld 31 Mar '06

31 Mar '06

Dynamic Languages Symposium 2006 - Technical Papers Call for papers Portland, Oregon, United States, October 22, 2006 http://www.dcl.hpi.uni-potsdam.de/dls2006/ The Dynamic Languages Symposium (DLS) at OOPSLA 2006 is a forum for discussion of dynamic languages, their implementation and application. While mature dynamic languages including Smalltalk, Lisp, Scheme, and Prolog continue to grow and inspire new converts, a new generation of dynamic scripting languages such as Python, Ruby, PHP, and JavaScript are successful in a wide range of applications. DLS provides a place for researchers and practitioners to come together and share their knowledge, experience, and ideas for future research and development. The Technical Papers track of DLS 2006 invites high quality papers reporting original research, innovative contributions or experience related to dynamic languages, their implementation and application. Accepted Papers will be published in the OOPSLA conference companion and the ACM Digital Library. Areas of interest include but are not limited to * Reflection and meta-programming * Very late binding, dynamic composition, and runtime adaptation * Actors and active objects * Innovative language features and implementation techniques * Development and platform support, tools * Language symbiosis and multi-paradigm languages * Experience reports and case studies * Interesting applications * Educational approaches and perspectives * Domain-oriented programming * Object-oriented, aspect-oriented, and context-oriented programming Submissions and proceedings We invite original contributions that neither have been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Papers are to be submitted electronically at http://www.dcl.hpi.uni-potsdam.de/node2006/ in PDF format. Submissions need to use the ACM format, templates for which can be found at http://www.acm.org/sigs/pubs/proceed/template.html. Important dates Submission of papers (hard deadline): June 1, 2006 (Thursday) Author notification: July 1, 2006 (Saturday) Final version due: July 11, 2006 (Tuesday) DLS Technical Papers Day: October 22, 2006 (Sunday) DLS Invited Talks Day: October 23, 2006 (Monday) Chair Robert Hirschfeld Hasso-Plattner-Institut, University of Potsdam, Germany hirschfeld(a)acm.org Program committee David Asher, ActiveState, United States Gilad Bracha, Sun Microsystems, United States Pascal Costanza, Vrije Universiteit Brussel, Belgium Richard P.

A How-To 3.9 from scratch needed
by William Hubbard 31 Mar '06

31 Mar '06

I've downloaded Squeak3.9a-7021.zip and uncompressed the following files: .DS_Store 6,148 Squeak3.9a-7021.changes 24,048,371 Squeak3.9a-7021.image 18,543,740 Now, no README, no clear install instructions from http://minnow.cc.gatech.edu/squeak/5645 or http://discuss.squeakfoundation.org/cgi-bin/ezmlm-browse?list=v3dot9 so I've decide to ask here: Should I assume to uncompress and copy from Squeak3.8-current-win-full.zipto the Squeak3.9a-7021 directory the following? Squeak.exe 1,077,760 SqueakFFIPrims.dll 30,720 SqueakV3.sources 14,542,313 I've made those assumptions, started Squeak and opened the "SqueakMap Package Loader": "The SqueakMap master server is running another version (2.1) than the client (2.0) You need to upgrade the SqueakMap package, would you like to do that now?" (at this point I asked myself: if it's really needed, why to ask?) "Yes" And after some recompilings: "Error ocurred when updating map SystemDictionary>>logChange: Would you like to open a debugger?" (see The log for Yes) ....

original ST-80 fonts
by Wolfgang Helbig 30 Mar '06

30 Mar '06

Hi, I am in the midst of porting Smalltalk-80-V2, released April 1, 1983, to Squeak 1.18. So far it works fine, but I am missing the original strike fonts, that made up the original DefaultTextStyle. (12 10-point fonts and 12 12-point fonts) that seem to be part of the said image. Any hints at how to get at the *.st files? I already found the PaloAlto-12 Font, but that turned out not to be what I am looking for. Are those vintage fonts gone for ever? Hope not, Greetings Wolfgang

Graphical Display of 100,000 objects
by Ron Teitelbaum 30 Mar '06

30 Mar '06

Hello all, I need to build something that shows the interaction of about 100,000 objects. The objects need to display by position and color. I have x,y positions and colors programmed. What is the best way to display these items? I saw some of the simulation programs, and that looks like that may be what I need. If you have some tips for hooking the simulations up to my objects please let me know. I tried just turning on and off single pixels but the result was too small. I could do some math and turn on more then one pixel to make the display larger but I thought I'd ask if anyone had some ideas for a better way to do this. Thanks, Ron Teitelbaum
