Recently, I configured Vim to remember undo information
after quitting. Now, from time to time, I happen to
be logged into the work server, and want to quickly edit
a file. I was concerned as to how that might confuse
my local Vim the next time I edit that same file. If
I start undoing after loading a file, it seems that Vim
will expect the contents to be something other than what
they are. Am I going to have a problem with this?
Undo information is stored in a file. If you have not configured 'undodir' and
just leave the default as storing the undo file in the same directory as the
edited file, then your Vim on both machines will see the same undo information.
You just need to be sure to configure both Vims to use that saved information
and I think you'll be fine.
I did put it somewhere in ~/.vim, as I was directed to do so
in the first article I found when Googling this. However,
the Vim on the work server is too old to support persistent
undo altogether, and I'm not really in a position to upgrade it.
If you also use an old Vim (or a Vim compiled without the persistent
undo feature), you won't be able to make use of undofiles, since the
undofiles contain a hash of the buffer content and changing the buffer
content without altering the undofiles will make the latter unusable.
If I may translate this into an action to take: set your .vimrc on your
work machine to remove any undo files that are present whenever it
changes a file (ie. use an autocmd, BufWrite).
You may also want to have a BufRead event that checks if there are undo
files present and, if so, to issue a warning that undo files will be
removed upon writing later.
