What we need to do in addition: Only do that when the class is referenced. #isUsedClass: does that, but it does integrate over all methods in the system. (I sometimes wonder if we should not late-bind accesses to globals, that is, just compile them as message sends to the environment). Marcus

Iceberg Pharo6.1 on Microsoft Windows 7

by Federico.Balaguer

Hello, I am trying to help some newbies to Smalltalk to use Iceberg on Pharo6.1 on Windows 7. I have a VirtualBox with Windows 7, I have the PharoLauncher installed from where I launch the Pharo 6.1 image. I cannot clone github repositories, I get a debugger: "LGit_GIT_ERROR: failed to get server certificate: The handle is in the wrong state for the requested operation" Do I have to compile libgit or libgit2 on the MSWindows virtual machine? thanks. federico -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo Laucher > Copy and subfolders

by phil＠highoctane.be

In the Pharo Launcher (Windows 19 here), I do a copy of an existing "image" (actually an entry in the right pane). The copy copies everything which is at the root and the subfolders but the subfolders end up being empty (apparently pharo-local and github-cache included). That's pretty annoying and makes the copy feature a lot less interesting. Is this the expected behavior? Recorded in https://github.com/pharo-project/pharo-launcher/issues/98 Phil

Re: [Pharo-users] Pharo 7 image, some more size reducation

Yes, these colours contrast a lot with each other, the idea is to paint object and distinguish easily from each other. If you can propose me a collection of colours to substitute one by one to the current colours, I can take a look.
