Dear Pharo Community, I would like to share with you the work of my past weekend, and announce "CategorySaver". It is a simple utility to periodically save (file-out) a list of categories given (wildcards accepted). You can find it here: http://smalltalkhub.com/#!/~sebnozzi/CategorySaver And invoke it like this: CategorySaverPanel new openInWorld What motivated me to do this was loosing hours of work after image "hang-ups", without having saved before. In those cases I thought that it would be cool to have some kind of background process, that at least saved some recent version of the code I was working on. But only now I got myself to write it. Hopefully you are not like me, you know what you are doing, the VM never hangs on you, and don't need this utility ;-) For all others I hope you might find it helpful. Best regards, Sebastian P.S. I am kind of a Smalltlak newbie. So if you find things to improve in the code, I am glad about any tip / critique. P.S. 2 -- I was amazed at how easy it was to code the UI! UI programming in Squeak/Pharo was always an area where I thought must be incredible complicated, but thanks to UITheme's builder (Polymorph?) it's a breeze. Good work! P.S. 3 -- Did I have to manually add [ANN] to the subject? My apologies in this case. Also my apologies if this kind of mails correspond to only one of the lists.
