  This is my collection of dotfiles  for my daily GNU/Linux environment, tweaked
  to  my  liking. If  you  wish  to  get the  same  setup  as mine,  follow  the
  instructions below.

  As you can see,  I personally use [[https://fishshell.com/][fish]] as my shell of  choice, and [[https://www.gnu.org/software/emacs/][Emacs]] using
  [[http://spacemacs.org][Spacemacs]] (still with Emacs keybinding) as my main text editor.

  I also  use [[https://github.com/resloved/i3][Resloved]]’s [[https://github.com/resloved/i3][fork]] of  [[https://github.com/Airblader/i3][i3-gaps]] with two [[https://github.com/jaagr/polybar][polybar]]  bars and [[https://github.com/tryone144][Tryone144]]’s
  [[https://github.com/tryone144/compton][fork]] of [[https://github.com/chjj/compton][Compton]]. The colors scheme for [[https://github.com/davatorium/rofi][rofi]], Emacs and polybar are chosen from
  the wallpapers using [[https://github.com/dylanaraps/pywal][pywal]].

* Features
  - Emacs configuration perfectly tailored for my own use
  - Beautiful and comfy i3 and polybar configuration
  - And enough information  below to get basically the same  distro install as I
    have on my main computer and my travel laptop.

  - And a bunch of other stuff, see below
  And some other stuff scattered around in my dotfiles.

  BTW, I use Arch.

* Installation
  Here will be  presented what I do to  get my system up and running  on a fresh
  Arch Linux install.  These installation instructions were written  in order to
  get an Arch  Linux distribution up and running with  the same configuration as
  my main computer’s and my travelling laptop’s configuration.

** Install Arch Linux
   I usually install Arch from the [[https://www.archlinux.org/download/][vanilla  ISO]], however I began using [[https://github.com/MatMoul/archfi][archfi]] to
   install easily the  distro (I’ve done it  so many times, I know  how it works
   now). Usually, my  distros will be installed on at  least two partitions, one
   dedicated to =/home=, the other to  the root partition =/=.

   If the computer  supports EFI bootloaders, the EFI partition  will be mounted
   on =/boot=. I  generally use rEFInd as  my boot manager, but if  you are more
   comfortable with  another one, just install  what you want. Be  aware that if
   you format  your =/boot= partition,  you will  delete all boot  managers that
   already exist; so, if  you are dual-booting, *DO NOT FORMAT  IT*. Yes, I made
   the mistake of wiping the Windows boot manager.

   The swap partition is always at least 4GB large, and I should have a total of
   12GB of combined RAM and swap. This means  on my main computer I have 16GB of
   RAM and 4GB of swap, but on my thinkpad I have 4GB of RAM and 8GB of swap.

*** Get the latest live system with fast mirrors
    When you boot into the live ISO, execute the following command:
    #+BEGIN_SRC sh :exports code :tangle no
      pacman -Sy reflector
      reflector --country France --country Germany --latest 200 \
                --protocol http --protocol https --sort rate \
                --save /etc/pacman.d/mirrorlist
    #+END_SRC
    This will update the packages from your  live ISO, and you will get the best
    mirrors for your  installation. Of course, change  the countries accordingly
    to your location.

*** Install the system
    Then you can use a custom script to ease your installation of Arch if you do
    not wish to do it manually.  Personally, I’ve done it several times already,
    I know  how the distro works,  I just want to  be able to install  my distro
    quickly now.
    #+BEGIN_SRC sh :exports code :tangle no
      wget archfi.sf.net/archfi
      # Or from matmoul.github.io/archfi if SourceForge is down
      sh archfi
    #+END_SRC
    Then, follow the  instructions and install Arch Linux.  Take the opportunity
    to install  as many packages  as you  need, mainly =yay=  which I use  as my
    package manager  (it is  just a  wrapper for =pacman=)  and AUR  helper, and
 =pacman-contrib= which will help us installing some packages later.

    Once your  system is  installed, reboot and  remove your  installation media
    from your computer.

** Install basic packages
   We will  need some  basic packages in  order to run  the bootstrap  file. So,
   let’s install =fish= (our shell running the script) and =git=.
   #+BEGIN_SRC sh :exports code :tangle no
     sudo pacman -Sy fish git yadm
   #+END_SRC

** Execute bootstrap
 =yadm= comes with  a very handy feature: its bootstrap  script. We can
   execute it by running the following command:
   #+BEGIN_SRC fish :exports code :tangle no
     yadm bootstrap
   #+END_SRC

   Notice these two header files, we can see this is a fish script, hence why we
   need fish (which is my daily shell anyway).
   #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
     #!/usr/bin/fish
     # -*- mode: fish -*-
   #+END_SRC
   Let’s take a look at what it does.

*** Get a correct keyboard layout
    I use  mainly the [[https://bepo.fr/wiki/Accueil][bépo]] layout,  a French keyboard layout  inspired by Dvorak
    layouts, however  I sometimes  need to  switch back  to the  standard French
    AZERTY or the American QWERTY layout, so  I make it so the Menu key switches
    for me my layout between these three. This makes it so my xorg configuration
    of my keyboard looks like this:
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      set keyboardconf \
      'Section "InputClass"
              Identifier "system-keyboard"
              MatchIsKeyboard "on"
              Option "XkbLayout" "fr,fr,us"
              Option "XkbModel" "pc104"
              Option "XkbVariant" "bepo,,"
              Option "XkbOptions" "grp:menu_toggle"
      EndSection'
    #+END_SRC
    So, let’s set it as our keyboard configuration.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Set keyboard layout #########################################################\n\n"
      echo $keyboardconf | sudo tee /etc/X11/xorg.conf.d/00-keyboard.conf
    #+END_SRC

*** Set our locale
    I use two main locales, the French and  US UTF-8 locales, and I like to keep
    the Japanese locale activated just in case.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      set mylocales "en_US.UTF-8 UTF-8" "fr_FR.UTF-8 UTF-8" "ja_JP.UTF-8 UTF-8"
    #+END_SRC
    Let’s enable these.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Set our locale ##############################################################\n\n"
      for item in $mylocales
          if test (grep -e "#$item" /etc/locale.gen)
              sudo sed -i "/$item/s/^#//g" /etc/locale.gen
          end
      end
    #+END_SRC

    This is my configuration I usually use when it comes to my locale.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      set localeconf "LANG=en_US.UTF-8
      LC_COLLATE=C
      LC_NAME=fr_FR.UTF-8
      LC_NUMERIC=fr_FR.UTF-8
      LC_IDENTIFICATION=fr_FR.UTF-8
      LC_TELEPHONE=fr_FR.UTF-8
      LC_MONETARY=fr_FR.UTF-8
      LC_PAPER=fr_FR.UTF-8
      LC_ADDRESS=fr_FR.UTF-8
      LC_TIME=fr_FR.UTF-8
      LC_MEASUREMENT=fr_FR.UTF-8"
    #+END_SRC
    Let’s set it as our system’s locale.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      echo $localeconf | sudo tee /etc/locale.conf
    #+END_SRC
    Now we can generate our locale!
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Generate locale #############################################################\n\n"
      sudo locale-gen
    #+END_SRC

*** Create some folders
    Let’s create  some folders we  might need  for mounting our  drives, Android
    devices and CDs.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Create directories for mounting #############################################\n\n"
      sudo mkdir -p /mnt/{USB,CD,Android}
      sudo chown $USER:(id -g $USER) /mnt/{USB,CD,Android}
    #+END_SRC

*** Set user’s shell to fish
    First of all, the bootstrap shell will set the user’s shell to fish.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Set fish as the default shell ###############################################\n\n"
      chsh -s /usr/bin/fish
    #+END_SRC

*** Install =yay= if it isn’t already installed
    Now we’ll need to be sure =yay=, our AUR helper, is installed on our system.
    If it is, we don’t need to  to anything. However, if it isn’t, we’ll install
    it manually.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      if ! test which yay
          printf "\n# Installing yay ##############################################################\n\n"
          cd
          mkdir -p fromGIT
          cd fromGIT
          git clone https://aur.archlinux.org/yay.git
          cd yay
          makepkg -si --noconfirm
      else
          printf "\n# yay already installed #######################################################\n\n"
      end
    #+END_SRC
*** Setting up Emacs: Installing Spacemacs
    Now, the  first thing  we want  to do  with Emacs  is install  its Spacemacs
    distribution. We’ll clone its =develop= branch into =~/.emacs.d=. We need to
    do this prior  to our dotfiles’ cloning because of  some submodules that are
    cloned  within  our =~/.emacs.d=  directory,  and  git  won’t let  us  clone
    Spacemacs in  an already existing and  non-empty directory. To make  sure it
    isn’t one, let’s delete any potentially existing =~/.emacs.d= directory:
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Installing Spacemacs ########################################################\n\n"
      rm -rf ~/.emacs.d
    #+END_SRC
    Now we can clone Spacemacs:
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      git clone --single-branch --branch develop https://github.com/syl20bnr/spacemacs ~/.emacs.d
    #+END_SRC
    And we can restore what might  have been deleted in our =~/.emacs.d/private=
    directory:
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      yadm checkout -- ~/.emacs.d/private/
    #+END_SRC

*** Set up dotfiles
**** Update our dotfiles’ remotes
     This line in the bootstrap script will test if the current user is using my
     username. If yes, it’s probably me.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       if ! test (echo "phundrak" | sed -e "s/^.*$USER//I")
     #+END_SRC
     If it is me  installing and using these dotfiles, I want  the remotes of my
     dotfiles to be set to ssh remotes using my ssh keys.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Update yadm’s remotes #######################################################\n\n"
       yadm remote set-url origin git@labs.phundrak.fr:phundrak/dotfiles.git
       yadm remote add github git@github.com:phundrak/dotfiles.git
     #+END_SRC
     I will also want to decrypt my encrypted files, such as said ssh keys.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Decrypt encrypted dotfiles ##################################################\n\n"
       yadm decrypt
     #+END_SRC
     Finally, let’s close this =if= statement.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       end
     #+END_SRC

**** Get =envtpl=
     Before  we set  our  dotfiles up,  let’s make  sure =envtpl= is  correctly
     installed. This package will be needed for generating our alt dotfiles.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf '\n# Install envtpl ##############################################################\n\n'
       yay -Syu python-envtpl-git
     #+END_SRC

**** Update our submodules
     Now we  can download the  various dependencies of  our dotfiles. To  do so,
     let’s run the following command:
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Getting yadm susbmodules ####################################################\n\n"
       yadm submodule update --init --recursive
     #+END_SRC

**** Generate our alt files
     Now this should be the last  manipulation on our dotfiles: let’s create our
     alternate files:
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Generating alt files ########################################################\n\n"
       yadm alt
     #+END_SRC

**** Symlink some system config files
     We have some files in [[file:ect/][etc/]] that are to be symlinked to =/etc=.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       for f in (find ~/etc -type f)
           set dest (echo $f | sed -n 's/^.*etc\(.*\)$/\/etc\1/p')
           sudo ln -s $f $dest
       end
     #+END_SRC

     We may also want to symlink our [[file:.nanorc][nanorc]] to the =/root= directory for when we
     use =nano= as =sudo=.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       read --prompt "echo 'Symlink .nanorc to root’s .nanorc? (Y/n): ' " -l nanoroot
       if test $nanoroot = 'y' || test $nanoroot = "Y" || test $nanoroot = ''
           printf "\n# Symlinking .nanorc to root’s .nanorc ########################################\n\n"
           sudo ln -s $HOME/.nanorc /root/.nanorc
       end
     #+END_SRC

*** Install basic packages
    Let’s set in a custom varible what packages we’ll be needing.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      set PACKAGES \
      asar ascii aspell-en aspell-fr assimp awesome-terminal-fonts base-devel bat \

    #+END_SRC
    These are the minimum  I would have in my own installation.  You can edit it
    however you want. Let’s install those.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Installing needed packages ##################################################\n\n"
      yay -S --needed $PACKAGES
    #+END_SRC

*** Installing Tryone’s Compton fork
    For some reason, I found installing directly  this fork does not work, and I
    need  to  install  it  after  I  installed  the  regular  compton  packages.
 =compton-tryone-git= will replace =compton= which will be removed.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Installing tryone’s compton fork ############################################\n\n"
      yay -S compton-tryone-git
    #+END_SRC

*** Enable some of our services
    We have  installed some packages which  require some services to  run. Let’s
    enable them.

**** Docker
     First, let’s activate Docker.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Enabling and starting Docker ################################################\n\n"
       sudo systemctl enable --now docker
     #+END_SRC

     Now, if we wish it, we can be  added to the =docker= group so we won’t have
     to type =sudo= each time we call Docker or Docker Compose.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       read --prompt "echo 'Do you wish to be added to the `docker` group? (Y/n): ' " -l adddockergroup
       if test $adddockergroup = 'y' || test $adddockergroup = "Y" || test $adddockergroup = ''
           sudo usermod -aG docker $USER
       end
     #+END_SRC

**** Emacs
     Emacs will run as a user service, which means it won’t be launched until we
     log in.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Enabling Emacs as user service ##############################################\n\n"
       systemctl --user enable --now emacs
     #+END_SRC

**** SSH server
     Maybe we  want to  activate an  SSH server on  our machine.  If so,  we can
     enable it. Let’s ask the question.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       read --prompt "echo 'Do you want to activate the ssh server? (Y/n): ' " -l sshdserver
       if test $sshdserver = 'y' || test $sshdserver = "Y" || test $sshdserver = ''
           printf "\n# Enabling ssh server #########################################################\n\n"
           sudo systemctl enable --now sshd
       end
     #+END_SRC

**** Ly
     Ly is a display manager based on ncurses which I find nice enough for me to
     use (I generally  don’t like using display managers). Let’s  enable it, and
     let’s disable tty2 while we’re at it (Ly uses it to run X).
     #+BEGIN_SRC fish
       sudo systemctl enable --now ly
       sudo systemctl disable getty@tty2
     #+END_SRC

*** Set up our fish shell
**** Install =fisher=
     We will be using =fisher= as our extensions manager for Fish. Let’s install
     it.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Installing fisher ###########################################################\n\n"
       curl https://git.io/fisher --create-dirs -sLo ~/.config/fish/functions/fisher.fish
     #+END_SRC
**** Install our extensions
     I generally use the following extensions in my Fish shell.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       set FISHEXTENSIONS \
       edc/bass franciscolourenco/done jethrokuan/fzf jethrokuan/z \
       jorgebucaran/fish-getopts laughedelic/pisces matchai/spacefish \
       tuvistavie/fish-ssh-agent
     #+END_SRC
     Let’s install these:
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       fisher add $FISHEXTENSIONS
     #+END_SRC

*** Install packages from git
    Now, let’s install some packages from git directly.

**** i3-gaps rounded
    I know we already installed =i3-gaps=  from the AUR, why reinstall it? Well,
    that is  certainly bad practices,  but this allowed  me to already  have the
    needed dependencies for building =i3=  installed. Now, let’s clone it, build
    it, and  install it. Doing  this is probably  very bad practices  though, be
    warned.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Install i3-gaps-rounded #####################################################\n\n"
      cd ~/fromGIT
      git clone https://github.com/resloved/i3.git i3-gaps-rounded
      cd i3-gaps-rounded
      rm -rf build
      autoreconf --force --install
      mkdir build && cd build
      ../configure --prefix=/usr --sysconfdir=/etc --disable-sanitizers
      make -j
      sudo make install
    #+END_SRC

**** Polybar Battery
     Now let’s install =polybar-battery=. This is a binary that  I’ll use in my
     [[file:.config/i3/config][i3 config]] to indicate my battery level. It also sends a notification on low
     battery and on charging completed.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Install polybar-battery #####################################################\n\n"
       cd ~/fromGIT
       git clone https://github.com/drdeimos/polybar_another_battery.git
       cd polybar_another_battery
       go get -u github.com/distatus/battery/cmd/battery
       make build
     #+END_SRC

     Now, we  have our binary, let’s  symlink it in our  local binary directory,
 =~/.local/bin=.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       ln -s polybar-ab ~/.local/bin/polybar-ab
     #+END_SRC

**** Reveal.JS
     I sometimes use Reveal.JS to make  presentations, and I set its location in
     my [[file:.spacemacs][dotspacemacs]] file to be in =~/fromGIT=, so let’s clone it there.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Install Reveal.JS ###########################################################\n\n"
       cd ~/fromGIT
       git clone https://github.com/hakimel/reveal.js.git
     #+END_SRC

*** Install Rust
**** Install the toolchains
     When using  rust, I bounce  between two toolchains, the =stable= toolchain
     and the =nightly= toolchain. To install them, I will use =rustup= which has
     already been installed.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Install the rust toolchains, nightly is the default one #####################\n\n"
       rustup default nightly
     #+END_SRC
     This will  both download the  nightly toolchain and  set it as  the default
     one. Yup, I like to live  dangerously. Now to install the stable toolchain,
     let’s run this:
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       rustup toolchain install stable
     #+END_SRC

**** Install some utilities
     We’ll need some utilities when developing Rust from Emacs, namely =rustfmt=
     and =racer=. Let’s install them with =cargo=.
     #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
       printf "\n# Add rust utilities ##########################################################\n\n"
       cargo install rustfmt racer
     #+END_SRC

*** Clean the =pacman= and =yay= cache
    Finally, we are almost done! Let’s clean the cache of =pacman= and =yay=.
    #+BEGIN_SRC fish :exports code :tangle ~/.yadm/bootstrap
      printf "\n# Clean the pacman and yay cache ##############################################\n\n"
      yay -Sc --noconfirm
    #+END_SRC
    You should  now run  a system  pretty close  to the  one I  have on  my main
    computer and my thinkpad.
