Change default location of vimrc
Another solution might be to create a symlink to you preferred location. I have my .vimrc in $HOME/.vim/.vimrc and symlink to it. This way I can have it in a git repo and backup it.
You must start vim with the command vim -u ./path/to/your/vimrcfile
vim -u NONE is a good way to start Vim without any plugin or customisation.
See :help starting.txt for more information.
The VIMINIT variable is my preferred method. The problem with aliasing vim with the -u flag is that if vim is opened in some way other than from the shell command your configuration won't get pulled in. Setting $VIMINIT does not suffer from this drawback. Check this out for more information.
export VIMINIT='source $MYVIMRC'
export MYVIMRC='~/.vim/vimrc' #or any other location you want
Note that Vim normally sets the MYVIMRC variable, though I'm not sure exactly what it's used for. Based on my testing, using VIMINIT in this fashion will result in it not being automatically set on startup as it would normally be. This is why I'm setting it myself.
This works for neovim too!
On Windows, I have the _vimrc that's in my home directory contain one line, source c:\path\to\my.vimrc.
I have not yet worked out a good way to move the entirety of my vimfiles folder, but that's less critical as it's all stuff I've installed from elsewhere. I.e., it'd be easy to restore if I lost it. (I know that I can change runtimepath but my problem is more coming up with a "good" way to do so.)
Update
After six years I extended slightly from what I mention in the comments below; as I put stuff into 'after' and wanted to just keep rtp clean I got something that has been solid for a while now. Today in my %USERPROFILE%\_vimrc I do hardcode the actual paths to things and it changes on every machine I use (and I basically do the same thing on *nix) but this gets copied around mostly-manually when setting up a new PC. I also have a version which I can use to launch Vim on another connected machine on the network, e.g. a co-worker's machine, so I get my config and all that, but the gist is:
set runtimepath^=E:/dotfiles/vim
set runtimepath+=E:/dotfiles/vim/after
set runtimepath-=~/vimfiles
set runtimepath-=~/vimfiles/after
runtime vimrc
and then %USERPROFILE%\_gvimrc just has one line:
runtime gvimrc
(Both vimrc and gvimrc are in the /dotfiles/vim folder and also on Bitbucket.)
I see two options, depending on your needs.
- Have ~/.vimrc import the other location
- create an alias in your bashrc alias vim="vim -u otherlocation"
