Hi,

I would like to know how to change the main Pharo window icon. I saw that there is a primitive for the title:
DisplayScreen class  >> primitiveWindowTitle:string: ; primitive: 'primitiveHostWindowTitle' module:'HostWindowPlugin'
but I cannot find one for the icon.
Should another primitive need to be implemented?

    {build.macos32x86,build.macos64x64}/pharo.cog.spur/Makefile

in setting the VM variable.  The file that associates the other icons with specific file types is 

    platforms/iOS//vm/OSX/Pharo-Info.plist

If you're changing the Pharo icon let me suggest you update the icon files themselves in the opensmalltalk-vm source tree.

If you're creating a new variant of the VM for some new purpose (say a special Lam VM) then let me suggest you add the icons to the opensmalltalk-vm source tree, creating special build directories for these VMs, such as {build.macos32x86,build.macos64x64}/lam.pharo.cog.spur/

If you want to do this privately, then take either of the approaches above and simply don't publish the edits.  You can write a script that takes an updated checked-out opensmalltalk-vm source tree and edits it with files from a specific repository.  I have such scripts and can help you with them.  Hint, pax is a very convenient directory hierarchy copying tool available at least on Mac OS X.  pax -rwlk will copy the trees under a sequence of directories into their corresponding places in a target tree.
