Dotfiles

Instructions for the dotfile repository on https://github.com/EloB/dotfiles.

Introduction

The dotfiles in this repository are installed using a bare Git repository. This method does not use symlinks (like most other dotfile repositories).

After the installation, all the dotfiles will be physically present in your home folder, yet, you will still have them under full version control.

Installation

curl -Ls https://bit.ly/install-dotfiles-now | bash

The URL https://bit.ly/install-dotfiles-now is simply a shortened link to the dotfiles-install.sh file in this Gist, and the above command downloads this file and executes it in a sub-shell.

In particular, the dotfiles-install.sh file does the following:

• Clone the dotfile repository to a bare Git repository into ~/.dotfiles
• Move your existing dotfiles to ~/.dotfiles.backup
• Check out all the dotfiles (and dot-directories) to your home directory

If you don't need your old dotfiles anymore, you can safely delete the created ~/.dotfiles.backup directory.

And Now?

Now all the dotfiles from the repository are installed in your home directory. However, as mentioned, you still have them under full version control via the bare Git repository in ~/.dotfiles.

To interact with the bare Git repository, you need the following alias:

alias dotfiles='git --git-dir=$HOME/.dotfiles --work-tree=$HOME'

With the dotfiles alias, you can now manage the dotfiles via the bare Git repository, just as you would with the git command:

Edited your dotfiles? No problem, commit and push the changes:

dotfiles add ~/.vimrc
dotfiles commit -m "Edit .vimrc"
dotfiles push

Pushed changes to the remote repository from another machine? Easy, just pull down the new version:

dotfiles pull

Want to know what's going on? Sure:

dotfiles status

Submodules

The dotfile repository supports submodules (Git repositories within another Git repository).

The case for submodules occurs typically with Vim plugins, if you install them with pathogen.vim by cloning the respective Git repository into a directory under ~/.vim/bundle.

Here are some common tasks when using submodules:

• Add a Vim plugin as a submodule to the repository:

  dotfiles submodule add https://github.com/tpope/vim-surround .vim/bundle/vim-surround
  dotfiles commit
  dotfiles push
  # Download files of submodule on local machine
  dotfiles submodule init

• Pull changes that inlude a newly added submodule on another machine:

  dotfiles pull
  dotfiles submodule init
  dotfiles submodule update

• List all submodules in the repository (including the commit that is used for each submodule):

  dotfiles submodule status

• Update the submodules in the repository to the newest commits:

  dotfiles submodule update --remote
  dotfiles add <changed_files>
  dotfiles commit
