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

I suspect when docs for wall say "without a file name" they may be referring to buffers with buftype=nofile . One way to get what you want would be to have the autocmd have bufdo call a simple function. E.g., some untested code to give the idea:

autocmd BufLeave,FocusLost * bufdo! call WriteFile()

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

I think the standard way of getting something like this automatic saving of buffers would be to set the autosave option in Vim.
