[Pharo-project] AioPlugin and SqueakSSL plugin included in Cocoa (please test)
by Esteban Lorenzano May 2, 2012

May 2, 2012

Hi, I added AioPlugin and SqueakSSL plugins in Cocoa builds. Aio tests in OSProcess are green, but some other fails, and I don't know the reason. Also, Zodiac tests are all green, but I think there are things missing. Can you test and provide feedback? link: https://ci.lille.inria.fr/pharo/job/Cog-VM/Architecture=32,OS=mac/lastSucce… Thanks, Esteban

[Pharo-project] Multiple worlds
by H. Hirzel May 2, 2012

May 2, 2012

Hello This issue http://code.google.com/p/pharo/issues/detail?id=3545 is about the feature of having multiple worlds. Status is 'Accepted'. I assume it is now in Pharo 1.4. How can I use it. The code I found from Sean is "Add a world:" WorldManager instance createOrSwitchToWorldNamed: 'JustAnotherWorld'. "Return to the default world:" WorldManager instance createOrSwitchToWorldNamed: 'Pharo'. What are the proper instructions? Thanks in advance Hannes

You can bug Igor... :-) There will be more documentation, but keep in mind that this is work in progress and therefore focus is to finish, not to document.
