Everyone has seen those dotfiles repositories on GitHub. There's lots of different ways to manage them, but the method I use now requires no extra tooling (other than git and a command line shell of your choice), no symbolic links to get files into the right locations, can be triggered from any directory on disk, and is easy to replicate on a new system.
Basically what we're going to do is set up a git repository at ~/.cfg or ~/.dotfiles or any directory within your home directory of your choosing (although you probably don't want to use ~/.config since that is the default value of [$XDG_CONFIG_HOME](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)), and a shell alias to help manage and control it.
Creating the Repo
If you're setting this up the first time, there's a few steps you'll need to take to set up. First, create the repository:
git init --bare $HOME/.dotfiles
This creates a "bare" git repository at ~/.dotfiles. Now we'll set up an alias to interact with it from any directory on disk. Add the following alias to your ~/.bashrc or ~/.zshrc or ~/.config/fish/config.fish file, then source the file:
# make sure the --git-dir is the same as the
# directory where you created the repo above.
alias config="git --git-dir=$HOME/.dotfiles --work-tree=$HOME"
The --work-tree=$HOME option sets the directory that the repository tracks to your home directory. Now, since there's probably more files in your home directory that you don't want in the repo than files you do want in the repo, you should configure the repo to not show untracked files by default. We can do that by setting a repository-local configuration option.
config config --local status.showUntrackedFiles no
Tracking Files
To track files in our new ~/.dotfiles repo, we just need to add them. From any directory on disk, you can run the following command to add your ~/.bashrc or ~/.zshrc or ~/.config/fish/config.fish file to your new dotfiles repo:
config add ~/.bashrc
config add ~/.zshrc
config add ~/.config/fish/config.fish
config commit -m "Add .bashrc/.zshrc/config.fish file"
config push
Installing on a New System
Of course, the main point of doing this is to easily sync your config across new machines. We can easily do this with a small bash script to initialize the system's dotfiles from your git repository.
#!/usr/bin/env bash
git clone --bare git@github.com:mrjones2014/dotfiles.git $HOME/.dotfiles
# define config alias locally since the dotfiles
# aren't installed on the system yet
function config {
git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME $@
}
# create a directory to backup existing dotfiles to
mkdir -p .dotfiles-backup
config checkout
if [ $? = 0 ]; then
echo "Checked out dotfiles from git@github.com:mrjones2014/dotfiles.git";
else
echo "Moving existing dotfiles to ~/.dotfiles-backup";
config checkout 2>&1 | egrep "\s+\." | awk {'print $1'} | xargs -I{} mv {} .dotfiles-backup/{}
fi
# checkout dotfiles from repo
config checkout
config config status.showUntrackedFiles no
Now, installing your dotfiles on a new system is as simple as running:
curl https://raw.githubusercontent.com/mrjones2014/dotfiles/master/scripts/config-init | bash
That's Really It
That's really all there is to it. Now you can easily add and track changes to dotfiles via your new config shell alias.
config add ~/.config/something/somefile
config commit -m "add somefile"
config push

Installing on a New System
You can run the following to get these dotfiles installed on your system. It will make a backup of your existing dotfiles.

Manual Config
Package Manamement
You'll need/want to install Homebrew. For Apple Silicon Macs you'll need to run the brew install script
as well as brew itself through Rosetta until Homebrew is updated to support Apple Silicon natively
See here for how to do so.
Packages
There are some global installations that are required for some of the shell and nvim CoC configuration. The check-globals.fish script should output help text
for installing them if they're missing.
Shell
You'll need to install Fish Shell before the shell config will work, since its a Fish config.
Neovim Config
The Neovim configuration is using some Lua-based plugins, like TreeSitter for syntax highlighting, Telescope for file finding and live grep which means you…
