Gary, I suppose I could suggest replacing some of the button bars with more compact iconic toolbars. Things like debugging over, into, etc. lend themselves well to that. The world menu will not make much sense if we ever get one window per shell. The biggest concern I have right now is speed. I'm not saying Pharo is too slow; I'm simply admitting that I do not know whether it is fast enough for some of the things I want to do. That leads to a question I should ask: Gwenael, without asking you to do anything just yet, is your updated parser in a state that it can installed and used? How hard is that to do? Would it be easy for you? Are you able and willing to make it available? What would I have to give up? It's a long story, but tripping over underscores is a problem for a couple of things I would like to do. Bill Wilhelm K.

Re: [Pharo-project] Problem with linux VM and Pharo
by Provoost, P (Paul) Feb. 11, 2009

Feb. 11, 2009

It happens on OpenSolaris too.Squeak runs fine but Pharo crashes almost immediately. When you look into the source code of sqUnixMemory.c you find a comment in the beginning stating that the memory management here is tricky. If you have plenty of memory a workaround is using the -memory commandline option. The maximum seems to be 2047 (MB)... Maybe someone with enough knowledge (Ian P. ?) can look into this problem?

[Pharo-project] another slice for popups cleaning and some questions
by Alain Plantec Feb. 11, 2009

Feb. 11, 2009

Hi all, I've uploaded another slice for popup and co cleaning (SLICE-MorePopUpAndCustomMenuCleaning-alain_plantec.1) - it Removes last PopUpMenu references. - it Removes some of CustomMenu uses (wherever it is possible to replace it with a simpler UIManager dialog). I've three questions: - EmphasizedMenu is never used, can we remove it ? - MorphicUIManager is subclassed by PSUIManager which is now the default UIManager. Several MorphicUImanager methods are redefined in PSUIManager. So I guess one can simply remove MorphicUIManager versions. Is it ok to do so ? (as an example, #chooseDirectory:from:, in MorphicUIManager, the code is using FileList but now we have the PSUIManager version) - last unrelated question, I've also seen that ListParagraph is never used, can we remove it ? now I am about to see how to kill MVCMenuMorph cheers alain
