[Pharo-project] Alien on powerpc
by John M McIntosh Dec. 7, 2008

Dec. 7, 2008

I've check in a number of changes into the main SVN tree, and into the Alien MC to start to providing support for PowerPC. I do have a somewhat functional api on the cpu type now, we are still working some details about how to deal with Float/Double versus integer, and I've yet to tackle the callback logic assembler. Tomorrow if I make more progress I'll check in the assembler/glue code for the PowerPC call pattern. -- = = = ======================================================================== John M.

Your code looks ok to me and should work fine; but you might try creating a DiskProxy in the manner above, and see if that cures your problem. If that doesn't fix it, then do you have an image (+ database) that you can share so I can investigate further?

[Pharo-project] Removing a trait from a class
by Hilaire Fernandes Dec. 5, 2008

Dec. 5, 2008

I can't remove a trait from a class using UI tools. (pharo 10050) How can I remove it programmatically ? Next with this same class, message from this trait are not reachable, the MNU is raised but the hierarchy is not right as IFIETayage1 is not a subclass of IFIExoMorph. However IFIExoMorph is using the same trait as IFIEtayage. It looks like there is mismatch in the classes with traits. (see screenshot) Now I realize my last istoa release suffer from this problem :) Hilaire -- http://blog.ofset.org/hilaire

[Pharo-project] about UI
by StÃ©phane Ducasse Dec. 5, 2008

Dec. 5, 2008

Hi I would like to ask you if you do not get the same proble, as me. When I do not know an application I try to clik on the pane to see if there is a menu and it is like blind testing... It would be great if the mouse would change when the pane can display a menu. Stef

[Pharo-project] Fwd: free fonts

Acually I looked into that a bit more and I would definitely recommend the DejaVu version over Vera. Apparently Vera only covers latin scripts, while DejaVu has nice Unicode coverage. I guess for the shapes/weights they have in common they are virtually identical. -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

http://www.pinvoke.com/font/ I think that for the demo mode we should get a better font since italic "" is not working well. Now it would be great to have a set of free font for pharo. stef
