Configuration files for my workstation. This helps to setup and maintain all the machines I use for work, or even in my free time. It is specially useful in the cases I have to start working with a new machine, server, VM, etc…

You can find some information about what are dotfiles in Github's dedicated page

Clone the repo to ~/.dotfiles and run the installation script:

cd ~
mkdir -p .config
git clone --recursive https://github.com/abravalheri/dotfiles .dotfiles
cd .dotfiles
./install --help

The dotfiles in this repository are organized using a layered approach. Groups of configuration files (and sometimes scripts/functions) with the same purpose form together a layer. A layer is represented by a single folder inside the dotfiles root, and this folder should mimic the same infrastructure of the home directory. For example, if a layer git wants to specify a ~/.config/git/config file, a file $dotfiles/git/.config/git/config should be present in the repository.

Layers can be classified as regular layers or shadow layers. Regular layers are implemented as folders starting with a /a-z/i char, while shadow layers are folders starting with an % char. Regular layers are meant to be used by default, while shadow layers are created with special purposes (e.g. being an alternative installation, providing complementary/extra functionality, creating companion configuration/scripts for a specific bundle, …). For example, the doom-emacs layer provides the preferable configurations for the standard dev environment, while %emacs.minimal is created as an experiment, to be installed in secondary machines, or with less powerful hardware. Similarly, the %wsl layer provide required functionality to the @wsl bundle and is not meant to be used standalone. The @full bundle will automatically discover and install all regular layers found in the repository.

Layers are installed using GNU Stow (tutorial), which makes per-layer installation easy:

stow -R layer1 layer2 …
# -R is optional in this case, it will update a layer in the case it is already installed

• Note: the ZSH configuration in this repository pre-compile files to speed-up starting times. Therefore every time a new layer that relies on ZSH is installed it is recommend to run make clean pre-compile. If you are unsure if the new layer uses ZSH, run the command just in case.

A bundle encapsulates one of more layers, being able to additionally install packages or run arbitrary scripts during installation time. Similarly to layers, bundles are folders located in the dotfiles root repository, however starting with an @ char. This folders contain a few files with lists of layers, programs/OS packages and scrips An example of how a bundle can be organized can be found bellow:

@bundle1
├── bootstrap.sh
├── layers.stow
├── formulas.brew
├── packages.pacman
├── packages.trizen
├── packages.apt
├── packages.pipx
├── rubygems.gem
└── finish.sh

The process of installing a bundle can be summarized in 5 steps:

1. Run bootstrap.sh scripts
2. Stow listed layers (*.stow)
3. Pre-compile ZSH scripts (make pre-compile)
4. Install packages (order: *.brew, *.apt or *.pacman + *.trizen*, *.pipx, *.gem)
5. Run finish.sh scripts

For all the steps, the installation script looks recursively for files and expands symbolic links. As a consequence, when creating bundles, it is possible to:

• improve organization by maintaining separated files and folder;
• re-use and compose bundles (one bundle can extend others), by including links to them inside its folder.
  • Example for creating a bundle that re-uses previous ones:

    mkdir @tmux+vim
    cd @tmux+vim
    ln -sr ../@tmux
    ln -sr ../@vim
    echo "tmuxp" > packages.pipx

Notice that, since the bootstrap.sh scripts run as the first step, it is possible generate other bundle files on the fly. The @full bundle is an example of how to use the bootstrap script to generate the list of layers to be installed. (It also take advantage of the rules in the .gitignore, by naming the generated file +local-layers.stow and avoiding them to be commited in the repository).

All the layer and package files (*.stow, *``*.brew, *.apt or *.pacman + *.trizen*, *.pipx, *.gem) are plain text files with one package name per line. Commented lines are allowed, by starting with a # char.

After the bootstrap script executes, the layers are stowed. Indeed, installing all the layers in a bundle can be done manually with the following one-liner:

stow -R $(< find -L $bundle -name '*.stow' -exec cat {} \; | uniq | grep -v '#')

With the layers installed, the ZSH files are compiled (make pre-compile) and the packages are installed using the correct package managers (if available). Package installation is similar to layer installation, as showed bellow:

sudo apt-get install $(< find -L $bundle -name '*.apt' -exec cat {} \; | uniq | grep -v '#')

It is important to emphasize that all the bundles are processed simultaneously, not one by one. In each stage, the equivalent action happens for all the bundles (e.g. install layers for all the bundles, then install packages for all the bundles, …).

Per-machine customization can be done using files/folder prefixed with one of the following strings:

• +local
• @local
• %local

These files/folders are not committed to the repository thanks to a rule in .gitignore, but are considered during runtime. So, for example, the following files can be created for customization purposes:

• ~/.config/vim/+local.vim
• ~/.config/zsh/+local.zsh

In the top-level dotfiles repository:

• folder is used for default installation of layers
• %folder is used for alternative installation of layers
• @folder is used for bundles
• +folder holds auxiliary files to the dotfiles installer itself, e.g. +lib.

Inside a bundle:

• @folder is used as a symlink to another bundle (reuse all the packages/scripts)

• %folder is used to partially reuse another bundle. It should be a regular folder that contains symlinks to specific files inside the target bundle. For example, in order to create a bundle that inherits packages.apt from %minimal, but avoid using %minimal layers, the following can be done:

  cd ~/.dotfiles
  mkdir -p @bundle/%minimal
  cd @bundle/minimal
  ln -sr ../../@minimal/pacakges.apt

WSL is supported via the @wsl bundle:

./install @wsl

However, to maximize user experience on WSL, a few extra manual steps are required:

• Install Vcxsrv on C:\Local\Apps\VcXsrv (or change the scripts in @wsl accordingly) - This enables GUI apps to run.
• Enable "systemd/upstart/init-like services" in WSL:
  • Make sure the script ~/.local/bin/start-services.sh can run sudo without asking for credentials.
  • This can be done by editing the sudoers file.

    sudo visudo
    # Add to the file the following line:
    %sudo ALL=NOPASSWD: /home/<USERNAME>/.local/bin/start-services.sh

  • Create a Windows shortcut to the VBS script @wsl/start-services.vbs to %APPDATA%\Microsoft\Windows\Start Menu\Programs\Start-up - This enables the script to run automatically when the user logs in.
  • Alternatively you can run the .sh script conditionally inside ~/.bashrc or ~/.zshrc.

You might also want to:

• Add the location \\wsl$\home\<USERNAME> to Windows Quick Access list.

• Add "executable links" targeting some GUI programs inside WSL to the Start Menu.

  This can be done by creating Windows shortcuts to VBA scripts inside the folder %APPDATA%\Microsoft\Windows\Start Menu\Programs.

  • Drag & drop with ALT pressed will create Windows shortcuts.
  • There are VBA scripts inside @wsl that can be used directly, or as an example.
