The problem is when I type "ZZ". In that case, the vim window closes; I don't see the error; and my file contents are lost.
Is there any way to implement this without having "ZZ" lose file contents? Maybe write to a new buffer instead of overwrite current buffer? At the very least, append to current buffer?
Actually, ideal for me would be if yapf just silently failed with syntax errors.
- yapf exit code is not 0
- No vim buffers are modified

Is it possible to print yapf syntax error to vim stdout or stderr, rather than write to a vim buffer?

Alright, I found a workaround:

So here's what I would like to see:
Note: if vim-yapf is used in this way, any errors will overwrite the current buffer. Make sure to check the buffer for errors before saving. If you save with :w, :undo will revert the buffer. If you save with :ZZ, the saved file will be overwritten with the yapf syntax error. It is recommended to Auto-backup your files so you can recover your work.

Note even with the workaround, I lose the most recent changes (the ones that caused error), but it's better than nothing
