How can I make Vim autosave files when it loses focus?

Question

I\'m used to my editors autosaving files when they lose focus. I recently switched to MacVim, and I can\'t recreate that behavior. I tried this:

autocmd Bu         


        

Answer 1

autocmd BufLeave,FocusLost * bufdo! call WriteFile()

function WriteFile()
   if (&buftype=="") && (expand("%:r") > "") && (&readonly==0)
      write
   endif
endfunction

This method has a side-effect that, you can only open one unamed buffer. If you open the second one, it would automatically be synced to the content of the first unamed buffer.
