Hi guys,

I need to run some Pharo code whenever the image starts. Similarly on (clean) quitting. What's the recommended practice?

Regards RG

Hello!

Every classes should be able to override the methods #startUp, #startUp:, #shutDown and #shutDown: in order to do some work.

Hi Cyril, doesn't seem to work in my case. Just for fun, I try to set a class instance variable to Time current in the class-side #startUp method and quit the image with saving. Upon restarting the image, the class instance variable is still nil. Anything else I have to ensure?

As Sven said I forgot that you need to register your class.

You can add this in the class side on Pharo 5-6:

"protocol: class initialization" initialize super initialize. SessionManager default registerToolClassNamed: self name

Yep, this makes more sense and, indeed, works. Thanks Raffaello
