Here's another variation on swapping to a file in another instance of Vim.
In Vim 7, this is what the SwapExists event is for. I use Vim on Windows accessing files via a samba mount onto the development server, and rely on the file type association to start Vim, and typically have half a dozen Vim instances, fighting for space with terminal sessions and applications, and so the swap file warning is a nuisance. Cured with:
function! AskVims() let full_name = escape(expand("<afile>:p"), ' ') for i in split(serverlist()) if i != v:servername if remote_expr(i, 'bufexists("' . full_name . '")') echo 'found in ' . i call remote_foreground(i) call remote_expr(i, 'foreground()') let v:swapchoice = 'q' return endif endif endfor echo "not found" let v:swapchoice = '' endfunction auto SwapExists * call AskVims()
Vim 7's distribution contains a file in the runtime/macros directory called editExisting.vim that does this already.
You could just copy it into one of your plugin directories or create a small editExisting.vim in your plugin directory that does this:
