Running code on program termination

[olliejohnson]

Is there a way to run a function when the program is terminated

I would wrap my code in a call and watch for the terminated error message.
I think I have a code snippet for this somewhere, I'll have a look for it.

Edit: This snippet allows for tidy-up when main function errors. You can inspect the err message to see if it matches the terminated error message and thus do some special action on terminate.

An alternative way would be to use os.pullEventRaw and thus not have the automatic termination error throwing. Your code will have to handle the terminate request event itself.
