How I Manage My Dotfiles
I've had my dotfiles (or rcfiles, or whatever you want to call them) in a GitHub repository for a while now and have really appreciated the consistency across machines that such a setup provides. I started with just my
vim files: colorschemes, plugins and rcfiles, but recently, I started work on a unified
bash configuration as well. This is how I have everything set up.
Between work machines, home machines and various other servers I've had access to, it's been a pain having a different working environment on each machine, so obviously some unified configuration was in order. A challenge to this, of course, is maintaining different options between my work machines and personal machines: some things needed to be specific to and unshared between each. I accomplish this in two ways:
- Things that are shared are kept in the
masterbranch of the repository;
anything that needs to be environment-specific is kept in a separate branch.
bashconfiguration has the option to load
localfiles which can be
branch-specific or not even kept in
Config files and plugins for
vim are laid out like so:
dotfiles |-- vim/ | `-- ... |-- vimrc |-- gvimrc `-- ...
It's pretty standard from that point: GUI-specific configuration in my
gvimrc, with a few platform-specific options for things like fonts and maximizing the window automatically on Windows:
if has("win32") set gfn=Bitstream_Vera_Sans_Mono:h10:cANSI au GUIEnter * simalt ~x elseif has("mac") set gfn=Bitstream\ Vera\ Sans\ Mono:h12 elseif has("unix") set gfn=Bitstream\ Vera\ Sans\ Mono\ 12 endif
bash configuration all lives in
bash_profile; most of it is related to setting up the prompt and environment, obviously. I don't get too fancy with my
bash environment, mainly things like setting
DISPLAY to the remote SSH host so that I can use X directly without forwarding if I'm on the LAN:
if [ -n $DISPLAY ]; then declare -x DISPLAY=`cut -d ' ' -f 1 <<< $SSH_CLIENT`:0.0 fi
I also shorten my username and the hostname of the machine if they're "familiar" enough to save space, and I color my prompt based on a unique (modulo the number of colors available in a plain
xterm-color) hash of the hostname. I also display
git repo status in my prompt, since I have a tendency to forget to switch branches.
Setting it all up on a new machine
My setup script will symlink all the files I've configured into the right place in the home directory, and will ask the user whether or not to move existing files to
FILENAME_old. So, when I log into a new machine, all I need to do is
git clone the repository and then run
setup.sh and I'm all set and ready to go.
