" Vim Plugin: Edit the file with an existing Vim if possible
" Maintainer: Bram Moolenaar
" Last Change: 2016 Mar 28
" To use add ":packadd! editexisting" in your vimrc file.
" This plugin serves two purposes:
" 1. On startup, if we were invoked with one file name argument and the file
" is not modified then try to find another Vim instance that is editing
" this file. If there is one then bring it to the foreground and exit.
" 2. When a file is edited and a swap file exists for it, try finding that
" other Vim and bring it to the foreground. Requires Vim 7, because it
" uses the SwapExists autocommand event.
" Function that finds the Vim instance that is editing "filename" and brings
" it to the foreground.

" Make sure the file is visible in a window (not hidden).
" If v:swapcommand exists and is set, send it to the server.
