Feature - kill SIGTERM behavior - Ask user to confirm when an application is running #1473

It would be nice if foot can prompt the user before closing (either via pressing "x" or through a "kill -s SIGTERM") when a program is running through it.

Here's an example of the behavior for KDE's Konsole:

Apologies if this is already possible. I have read through the man page for foot and foot.ini and didn't find anything close to this kind of feature.

Thanks in advance!

The implementation of that konsole feature is rather hacky and still has open bugs from 2006.

I have to say I'm not really interested in playing the guessing game of trying to figure out whether there are still running applications or not (hint: there's always something running).

Especially when you start considering cases like foot nvim etc.

I totally understand. Thanks for the feedback.

Would an option to just always prompt before closing regardless of a process running or not make any sense? (I think that would get annoying pretty quickly...). Enabled via the config file.

If not then do close this issue/feature request!

Thanks again for your time.

Given that we don't use any toolkit, I'd like to keep user facing GUI elements like this to a minimum.

I also don't think always warning is very useful. It'll only get annoying, and users are likely to either just disable it, or automatically dismiss it, regardless of whether something is running or not.

Any way to run a script before closing? This could solve this problem, if the script could decide whether to close the window or not.

Any way to run a script before closing?

You'd need more than just a script that runs before closing to replicate that Konsole feature. It'd also need some way to communicate to foot "ignore this close operation".

... if the script could decide whether to close the window or not.

Only foot itself can "decide" that. Having the decision influenced by a different process would require some kind of IPC.

Yes, that was the idea, asking foot to abort closing the window. Is there currently any way to do this?

No.
