* Introduction
  :PROPERTIES:
  :CUSTOM_ID: Introduction-cd5792cd
  :END:
  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
  :PROPERTIES:
  :CUSTOM_ID: Install_Arch_Linux-ac7ad3b2
  :END:
  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 two partitions: ~/home~ and ~/~
  (root).

  If the computer supports EFI bootloaders, the EFI partition will be mounted on
  ~/boot/efi~. I generally use ~systemd-boot~ 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 when I used to dual-boot.

  In order to use the  ~suspend-then-hibernate~ systemd command, it is necessary
  to have a swap  partition at least twice the size of  your installed RAM. That
  is because  when this command  will be  run, the system  will try to  save the
  current state of your machine, stored in  your RAM, to the swap filesystem. If
  there is not enough space, the command will fail, and you won’t be able to use
  this command.

** Get the latest, fastest mirrors
   :PROPERTIES:
   :CUSTOM_ID: Install_Arch_Linux-Get_the_latest_fastest_mirrors-765401c9
   :END:
   When you boot into the live ISO, execute the following command:
   #+BEGIN_SRC sh
     pacman -Sy reflector
     reflector -c FR -c DE -c BE -l 200 -p http -p https --sort rate \
               --save /etc/pacman.d/mirrorlist --verbose
   #+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. In  my case,  I  am only  interested in  French, German,  and
   Belgian mirrors.

** Install the system
   :PROPERTIES:
   :CUSTOM_ID: Install_Arch_Linux-Install_the_system-3ff49aa6
   :END:
   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. I’ll need to download  the script with ~wget~, but apparently it
   isn’t installed by default on Arch ISOs anymore, so I’ll need to install it.
   #+BEGIN_SRC sh
     pacman -S wget
   #+END_SRC

   Now, let’s grab the script. You can check it on [[https://github.com/matmoul/archfi][Github]].
   #+BEGIN_SRC sh
     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.

* Execute bootstrap
  :PROPERTIES:
  :HEADER-ARGS:fish: :tangle ~/.config/yadm/bootstrap :shebang "#!/usr/bin/fish" :exports code :mkdirp yes
  :CUSTOM_ID: Execute_bootstrap-e37054ef
  :END:
  With the installation of  Arch with ~archfi~, I will have  [[https://github.com/Jguer/yay][yay]], an AUR helper,
  installed. This will  allow me to have some basic  packages installed in order
  to run  the bootstrap  described below.  So, let’s  install ~fish~  (our shell
  running the script), ~git~, and my dotfiles manager ~yadm~.
  #+BEGIN_SRC sh
    yay -Sy fish git yadm
  #+END_SRC

  ~yadm~  comes with  a very  handy  feature: its  bootstrap script.  It can  be
  executed automatically once the dotfiles are cloned with yadm:
  #+BEGIN_SRC sh
    yadm clone https://labs.phundrak.com/phundrak/dotfiles
    # or if labs.phundrak.com is down or too slow for you
    #yadm clone https://github.com/phundrak/dotfiles
  #+END_SRC

  Let’s take a look at what it does.

** Decrypt private yadm files
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Decrypt_private_yadm_files-68af7157
   :END:
   Some  private  files are  stored  encrypted  in  the  repository of  my  yadm
   dotfiles. I will need them later on during the bootstrap execution.
   #+BEGIN_SRC fish
     if test "$USER" = 'phundrak'
         yadm decrypt
     else
         whiptail --yesno "Decrypt private files?" 8 40 && yadm decrypt
     end
   #+END_SRC

** Get a correct keyboard layout
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Get_a_correct_keyboard_layout-77d24b30
   :END:
   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
     set keyboardconf \
     'Section "InputClass"
             Identifier "system-keyboard"
             MatchIsKeyboard "on"
             Option "XkbLayout" "fr"
             Option "XkbModel" "pc104"
             Option "XkbVariant" "bepo_afnor"
             Option "XkbOptions" "caps:ctrl_modifier"
     EndSection'
   #+END_SRC

   So,  let’s  ask  the  user  if  they   want  to  set  it  as  their  keyboard
   configuration.
   #+BEGIN_SRC fish
     printf "\n# Set keyboard layout #########################################################\n\n"
     whiptail --yesno "Would you like to set your keyboard layout to the bépo layout?" 8 55
     if test $status -eq 0
         echo $keyboardconf | sudo tee /etc/X11/xorg.conf.d/00-keyboard.conf
     end
   #+END_SRC

** Set our locale
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Set_our_locale-e74d772a
   :END:
   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
     set mylocales "en_US.UTF-8 UTF-8" "fr_FR.UTF-8 UTF-8" "ja_JP.UTF-8 UTF-8"
   #+END_SRC

   I’ll let the user accept them one by one.
   #+BEGIN_SRC fish
     printf "\n# Set locale ##################################################################\n\n"

     for item in $mylocales
         whiptail --yesno "Set the \"$item\" locale?" 8 40
         if test $status -eq 0 -a (grep -e "#$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
     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 if the user whishes to.
   #+BEGIN_SRC fish
     whiptail --yesno "Do you agree to have the following locale set?\n\n     $localeconf"  20 43
     if test $status -eq 0
         echo $localeconf | sudo tee /etc/locale.conf
     end
   #+END_SRC

   Now we can generate our locale!
   #+BEGIN_SRC fish
     printf "\n# Generate locale #############################################################\n\n"
     sudo locale-gen
   #+END_SRC

** Create some folders
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Create_some_folders-bf701387
   :END:
   Let’s create  some folders  we might  need for  mounting our  drives, Android
   devices and CDs.
   #+BEGIN_SRC fish
     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
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Set_user’s_shell_to_fish-1a794be2
   :END:
   First of all, the bootstrap shell will set the user’s shell to fish.
   #+BEGIN_SRC fish
     printf "\n# Set fish as the default shell ###############################################\n\n"
     whiptail --yesno "Set the current user’s default shell to fish?" 8 50
     if test $status -eq 0 -a ! "$SHELL" = '/usr/bin/fish'
         chsh -s /usr/bin/fish
     end
   #+END_SRC

** Install basic packages
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Install_basic_packages-17173316
   :END:
   Let’s set in a custom varible what packages we’ll be needing.

   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

** Tangle configuration files from Org files
   :PROPERTIES:
   :CUSTOM_ID: Execute_bootstrap-Tangle_configuration_files_from_Org_files-cc524361
   :END:
   Before tangling our  configuration files, we need to  create some directories
   first so our files can be properly tangled. Here’s the list of directories we
   need to create:
   #+NAME: dirs-tangled-files
   | $HOME/.config/awesome       |
   | $HOME/.config/awesome/theme |
   | $HOME/.config/emacs/private |
   | $HOME/.config/fish          |

   #+BEGIN_SRC emacs-lisp :var dirs=dirs-tangled-files
     (mapconcat (lambda (x) (format "mkdir -p %s" (car x)))
                dirs

   The next step is  to tangle all the Org files. Here is the list of files that

   :END:
   Now,  the first  thing we  want to  do with  Emacs is  install its  Spacemacs
   distribution.  We’ll clone  its =develop=  branch into  =~/.config/emacs=. We
   need to  do this prior  to our dotfiles’  cloning because of  some submodules
   that are cloned within our =~/.config/emacs=  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  =~/.config/emacs=
   directory:

     rm -rf $HOME/.config/emacs $HOME/.emacs* .spacemacs

   Now we can clone Spacemacs:
   #+BEGIN_SRC fish
     git clone --branch develop https://github.com/syl20bnr/spacemacs ~/.config/emacs
   #+END_SRC

   And we can  restore what might have been deleted  in our =~/.emacs.d/private=

    Emacs will run as a user service,  which means it won’t be launched until we
    log  in. However,  the service  won’t be  started immediately,  I personally
    prefer to start a standalone instance  in which installing and compiling the
    Emacs packages  will happen,  and then once  that is done  I will  start the
    service.

    Ly is a display manager based on ncurses  which I find nice enough for me to

    ~acpilight~ is our  utility managing the brightness of our  screen. There is

    Thanks  to the  AUR  package ~nordvpn-bin~,  I no  longer  have to  manually

    that we should activate:
    #+BEGIN_SRC fish
      sudo systemctl enable --now nordvpnd
    #+END_SRC

    Let’s also set  its default protocol to  UDP. This will allow me  to use any
    port while  connected to  any WiFi  as long  as the  443 port  is available.
    Because yes, I do  connect to a WiFi that blocks  some important ports, such
    as  the IMAP  and SMTP  ports. Thanks  University of  Paris 8  for being  SO
    paranoid.

   Let’s  also  symlink  the  ~plock~  script ([[file:bin.org::#Lock-635fcb38][source  here]])  to  ~/usr/bin~  so
   ~xss-lock~ can find it.

*** Reveal.JS

    I sometimes use  Reveal.JS to make presentations, and I  set its location in

    When using Rust, I bounce between two toolchains, the ~stable~ toolchain and
    the  ~nightly~ toolchain,  although  I try  to stick  with  Rust Stable.  To
    install  them,  I  will  use  ~rustup~  which  has  already  been  installed
    previously.
    #+BEGIN_SRC fish
      printf "\n# Install the rust toolchains, nightly is the default one #####################\n\n"
      rustup default stable
    #+END_SRC

    This will both download the stable toolchain  and set it as the default one.
    Now to install the nightly toolchain, let’s run this:
    #+BEGIN_SRC fish
      rustup toolchain install nightly
