ST3: how to tell if file closed by user vs sublime exit

[barth]

Hi

How can tell whether a view is being closed by user (^w or click on close button or even file > close all files) versus sublime being shut down. Either case triggers EventListener on_close but I need to distinguish between the two. Is this possible?

Thanks

I think that there is no way to tell. However, a similar question was asked recently, which may be helpful:

Execute command on exit

Hey, I'm currently working on a SSH file forwarding plug-in and was wondering if you're able to exectue a specific Window Command on plug-in unload or at least sublime exit. The reason for this is because I'm working with temporary files that act as live ssh files/buffers. Each of these files/buffers has it's very own view with it's very own SSH address assigned. Now I have a fully functional Window command that closes ONLY those SSH views, however I'd like to close them automatically on exit …

there is an outstanding feature request for a callback on application/window close here:

Currently, your only way is to launch a child process that checks whether its parent still exists and performs actions when it doesn’t, after which it terminates itself.
