I don't have a Mac, and I'm afraid that I was thinking in terms of the Unix VM code base. My expectation is that a Unix VM (interpreter, Cog, Spur) running on Mac with X11 display should work with the current RemoteTask, exactly as on on Linux. But I have not personally tried it, and I am not really sure what would be required to get it working on the standard released Mac VMs. Sorry for the confusion. Dave

Re: [Pharo-users] [Pharo-dev] [ANN] Multiple Desktop support for Pharo 5

by Torsten Bergmann

Hi Hannes, I've just added support for this. Update your version or load latest from Catalog. You can then use the menu or CTRL + D and then CTRL + R like "Desktop" -> "Rename" so now you have: CTRL + D and then CTRL + D like "Desktop" -> "Desktop switcher" (a custom Spotter) CTRL + D and then CTRL + F like "Desktop" -> "Fullscreen" (toggles fullscreen) CTRL + D and then CTRL + O like "Desktop" -> "Overview" CTRL + D and then CTRL + P like "Desktop" -> "Previous" CTRL + D and then CTRL + N like "Desktop" -> "Next" CTRL + D and then CTRL + R like "Desktop" -> "Rename" Side note: ========== If you work on Windows take care: if you already switch to Spur VM https://pharo.fogbugz.com/f/cases/17289 the "DesktopManager" and "QuickAccess" goodies will not work as CTRL keys are not handled correctly anymore in pharo-spur32 (for win, dated 14.12.2015) compared to non-spur VM. Esteban knows about this already and followup with merged VM code in the next weeks. As always a time issue. I have to stop in Pharo5.0 Latest update: #50495 (last non-spur image) with most of my stuff for that reason. Hope this helps and happy x-mas. Have fun T. > Gesendet: Montag, 21.

The OSProcessPlugin in found everywhere. It is called 4.3.3 Cog everywhere (Pharo Spur, Squeak 4.6, Squeak 5.0) OSProcess accessor osppModuleVersionString. In Squeak there is a UnixOSProcessPlugin.bundle in Resources, in Pharo Spur there is a plugins directory containing dylib's, but nothing named close to OSProcess. Is there any progress made to forkSqueak on mac since 2010? Stephan

Hello Torsten the desktops are named 'Desktop 1' 'Desktop 2' 'Desktop 3'. Is it possible to change these names?

The XDisplayControlPlugin is used to close the socket connection to the X display in the new child VM/image. You may also be missing the OSProcessPlugin. Note, I developed this in Squeak on Linux, so it may be that some work would be needed for Pharo. If you have a Squeak image handy, you might want to look at it there. Dave
