Use Vim? Use Dropbox? Here is an easy way to have your whole vim setup follow you around the internet (or at least to any computer you sync your Dropbox account to)
Move your current
~/.vim setup to your Dropbox share. I just use a directory called
~/Dropbox/vim. Rename your
~/Dropbox/vim/.vimrc file to
~/Dropbox/vim/vimrc.vim (this step is entirely optional, but the source command in the following section will have to be updated accordingly.
Now, update your
~/.vimrc file to the following contents
This will configure vim to look at
~/Dropbox/vim as it's runtime path for all plugins, and configuration and then source your new
vimrc.vim file at startup.
Now all you need to do is add this new, short two-line vimrc file to any computer where your Dropbox is synced and you can have your full vim setup instantly. New plugins or changes you make to your configuration will be synced to Dropbox and follow you around to all your other machines.
