Hi,

is there a way to register arbitrary code to be run at image start-up and shutdown?

Thanks Michel

Sure, that is possible and common.

Have a look at the 'system startup' protocol of TBehavior (as implemented by classes) and look for the startUp & shutDownmessages.

There is also the 'snapshot and quit' protocol of SmalltalkImage with messages like addDeferredStartupAction: and addToStartUpList:

In newer Pharo images (5+ I think), SessionManager is your friend, a cleaner rewrite.

Thanks Sven, I'll take a look.
