I think :rundo and :wundo were created for this purpose. From :help :rundo,
You can use these in autocommands to explicitly specify the name of the
history file. E.g.: >
au BufReadPost * call ReadUndo()
au BufWritePost * call WriteUndo()
func ReadUndo()
if filereadable(expand('%:h'). '/UNDO/' . expand('%:t'))
rundo %:h/UNDO/%:t
endif
endfunc
func WriteUndo()
let dirname = expand('%:h') . '/UNDO'
if !isdirectory(dirname)
call mkdir(dirname)
endif
wundo %:h/UNDO/%:t
endfunc
You should keep 'undofile' off, otherwise you end up with two undo files for
every write.
You can use the |undofile()| function to find out the file name that Vim would
use.
