Hi list, Is there a setting for autosaving the image every few minutes? Is this a bad idea? How do I save the image programmatically? Thanks in advance!

I would think it is a bad idea. Because: - you could easily end up with inconsistent, and therefore unusable autosaved image - saving manually is not such a big chore - saving monticello packages adds protection as well, and it also offers versioning - even if everything else fails, you still have your .changes file BTW, I think that rebuilding your work image from the blank one using your packages periodically is a good habit.

Well, autosaving image is not so scary thing and it is possible without troubles. And it is a must for any image-based persistency solution. Current Aida one-click has for instance an hourly snapshot enabled by default. Also I have all my images snapshoted automatically every hour, being production or development. Both VW and gradually Pharo ones too. Not to mention that image running Squeak website snapshots every hour for years too. You snapshot Squeak/Pharo image by: SmalltalkImage current saveSession In any case, we need to recheck and cleanup that snapshot procedure to be safe and viable solution for persistency, if there are really some problems yet there to popup. If visualWorks can spapshot cleanly, why Pharo cannot? Best regards Janko S, Davorin Rusevljan piše:
