My Dotfiles

It's time to give my dot files a home. This is it.

Setup

I'm using the pattern outlined in hacker news a few years ago where $HOME is the git work tree and the repository is placed in a hidden directory.

Assuming an SSH key with access to the repository is available to the ssh-agent, the following will clone the dotfiles, populate $HOME, install bash-it, and tpm for tmux.

    git clone --bare https://github.com/wlahti/dotfiles "$HOME/.dotfiles"
    alias dotfiles='git --git-dir="$HOME/.dotfiles/" --work-tree="$HOME"'
    dotfiles config --local status.showUntrackedFiles no
    dotfiles config --local core.excludesFile "$HOME/.dot-gitignore"
    dotfiles checkout -f # destroys any local changes

    if [ ! -d ~/.bash_it ]; then
        git clone --depth=1 https://github.com/Bash-it/bash-it.git ~/.bash_it
        ~/.bash_it/install.sh --silent --no-modify-config
        echo 'bash-it enable completion ssh terraform tmux xterm' | bash -i
    fi

    if [ ! -d ~/.oh-my-zsh ]; then
        git clone --depth=1 https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh
    fi

    if [ ! -d ~/.zsh-syntax-highlighting ]; then
        git clone --depth=1 https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.zsh-syntax-highlighting
    fi

    if [ ! -d ~/.tmux/plugins/tpm ]; then
        git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
        ~/.tmux/plugins/tpm/bin/install_plugins
    fi

If the repo is private and the SSH key is available as a file and not loaded into the agent, the GIT_SSH_COMMAND environment variable can be used to point to the key to use for the clone.

    GIT_SSH_COMMAND="ssh -i $HOME/.ssh/id_rsa_deploy" git clone --bare git@github.com:sykesm/dotfiles "$HOME/.dotfiles"

The following is an outline of a cloud-init based setup for a development box. The keys have been removed and need to be replaced with the appropriate material.
