[Pharo-project] Old smalltalker is slightly lost
by KasperOsterbye Dec. 17, 2011

Dec. 17, 2011

15 years ago I did a lot in Smalltalk, and have done some recreational meta programming along the way. However, I now wanted to do something where I was in need of drawing a diagram with x and y axes on what I presume might be called a Canvas. I lack a simple tutorial to get me started. I have looked at many, but they seem to presume I want to draw on the world "openInWorld". I should like not to scatter my world with line fragments and points, but keep it inside a "normal" window with borders, a background color (i.e. not a see through window). I have gone dead in two approaches. First attempt is to use a SystemWindow, and then draw on the canvas I presume is there somewhere. I have just not been able to figure out how to find the canvas of that SystemWindow, nor what method presumeable does the painting. Second attempt is to use a SystemWindow, and then add (addMorph:) line and circle morphs for my diagram. But it seems something is missing in my understanding there as well. While it is fun that I can open circles and other stuff in "world", it is not what I need. Small hits or direct solutions more than welcome. -- Kasper -- View this message in context: http://forum.world.st/Old-smalltalker-is-slightly-lost-tp4191137p4191137.ht… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Help with #cleanUpForRelease is broken: MessageNotUnderstood: ByteSymbol>>run:with:in:
by Mariano Martinez Peck Dec. 16, 2011

Dec. 16, 2011

Hi guys. Somethine is very strange. I cannot do ScriptLoader new cleanUpForRelease because I get an error saying MessageNotUnderstood: ByteSymbol>>run:with:in: So....all the info is here: http://code.google.com/p/pharo/issues/detail?id=5005 I checked and it is not related to methodDictionary rehash..... so, do you have in mind what can we be doing in cleanUpForRelease which causes tu put symbols in the value of the association of a MethodDictionary rather than a CompiledMethod ??? Thanks! -- Mariano http://marianopeck.wordpress.com

[Pharo-project] When is a freeze a bug or me fiddling too much
by Kasper Ãsterbye Dec. 16, 2011

Dec. 16, 2011

Hi all, I have spend some time fiddling with Pharo, wonderful! I have always had a tendency to redefine vital methods in ST, and sometimes that kills it (typically it just hangs). Pharo seems a little more prone to that than what I was used to. In particular, I seem to have a tendency to spot methods where inserting a "self halt" will cause the pre-debugger to open a new pre-debugger to open a new pre-debugger to.... My question is - are there any guidelines on when I should just live with it, or if it is a bug? Would there be anyone interested in me collecting a list of the things that I stumble upon that make the image freeze? Best, Kasper

It was always a mess for me. I didn't even remember what I did to make it work. I think I took the SqueakFFI dll from an older Cog VM or from the one build by Jenkins or something like that. Until I make it work. But out of the box, the FFI is not working. Maybe it has been fixed. You can try the very last VM of Eliot (since there is no Jenkins for Windows yet) http://www.mirandabanda.org/files/Cog/VM/VM.r2522/cogwin.zip is it working? > > A side comment for whoever maintains ConfigurationOfODBC...
