Warn before closing without saving

[cool-RR]

There's a certain workflow that I'm doing with Excel that I want to do with VisiData instead. Every day I open a CSV file, edit some cells, and close it.

One basic feature in a program like Excel is that if I attempt to close the program without saving, it prompts me to save. VisiData doesn't do that, which makes sense for most VisiData usage. However, for this specific usage, I would like VisiData to prompt me if I attempt to close it without saving. I know of the guard-sheet feature, but if I understand correctly it doesn't really look at whether the file was saved or not.

Is there a way to do that with VisiData?

Saving does flip the hasBeenModified attribute, which is what options.quitguard uses to determine whether to guard the sheet! I think setting options.quitguard = True should get you what you want.

I tried that, and it worked well, but then I attempted to turn in on using the --quitguard command line argument (because I only want it to happen on this specific workflow, not all of my files), and when I use the command line argument, the behavior is different. I get the quit guarded sheet "Log"? message even when the file is unchanged.

Sounds like a bug! Can you write a report?
