* Bootstrap Script
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 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. For
instance, my current computer has 32 GB of RAM, hence my SWAP
partition is 16 GB large.

*** Get the latest, fastest mirrors
When you boot into the live ISO, execute the following command:
#+BEGIN_SRC sh
pacman -Sy reflector
reflector -c FR,DE -l 20 -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
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 any
more, 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 ~paru~ which
I use as my package manager (it is just a wrapper for ~pacman~) and AUR
helper, and ~pacman-contrib~ which will help us to install 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
:END:
The first thing I will do is add the [[https://aur.chaotic.cx/][Chaotic AUR]] repository to get
access to ~paru~ as well as some AUR packages without the need of an AUR
helper (ironic considering ~paru~ is one). We can then install ~fish~,
~git~, and ~paru~:
#+BEGIN_SRC sh
sudo pacman -S fish git paru
#+END_SRC

And now that ~paru~ is available, we can install ~yadm~:
#+BEGIN_SRC sh
paru -S 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
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
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
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_DK.UTF-8
LC_COLLATE=C
LC_NAME=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_MEASUREMENT=fr_FR.UTF-8"
#+END_SRC

Let’s set it as our system’s locale if the user wishes 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
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
First, 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

All these packages will be installed with the command ~paru -S
--skipreview --needed~ to prevent it from nagging me about the PKGBUILD
when I want to install something from the AUR, and if something is
already installed it paru won’t try to reinstall it.

Finally, I wish to install some custom packages for which I’ve written

them immediately.

*** Tangle configuration files from Org files
Before tangling our configuration files, we need to create some
directories first to make sure our files can be properly tangled.
Here’s the list of directories we need to create:
#+NAME: dirs-tangled-files
| $HOME/.config/fish     |
| $HOME/.config/gtk-2.0  |
| $HOME/.config/gtk-3.0  |
| $HOME/.config/ncmpcpp  |

| $HOME/.config/picom    |
| $HOME/.config/yadm     |
| $HOME/.local/bin       |
| $HOME/.stumpwm.d       |
| $HOME/org/capture      |

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

#+RESULTS[250efd14cab8a0f03e5520e0d0bd96aa311aa45f]: gen-dirs-tangle

mkdir -p $HOME/.config/yadm
mkdir -p $HOME/.local/bin
mkdir -p $HOME/.stumpwm.d
mkdir -p $HOME/org/capture

Our code to generate such directories looks like this:

files that are to be tangled:

using my username. If yes, it’s probably me.
#+BEGIN_SRC fish
if test "$USER" = 'phundrak'
#+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
printf "\n# Update yadm’s remotes #######################################################\n\n"
yadm remote set-url origin git@labs.phundrak.com:phundrak/dotfiles.git
#+END_SRC

I will also want to decrypt my encrypted files, such as said ssh keys.
#+BEGIN_SRC fish
printf "\n# Decrypt encrypted dotfiles ##################################################\n\n"
yadm decrypt
#+END_SRC

Finally, let’s close this ~if~ statement.
#+BEGIN_SRC fish
end
#+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
printf "\n# Getting yadm susbmodules ####################################################\n\n"
yadm submodule update --init --recursive
#+END_SRC

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

**** Systemd-timesyncd
This service enables time syncing with the NTP protocol, so I can be
sure my computer’s time is correct. The service first needs to be
enabled:
#+BEGIN_SRC fish
printf "\n# Enabling timesync ###########################################################\n\n"
sudo systemctl enable --now systemd-timesyncd
#+END_SRC

Now, let systemd know I want to use the NTP protocol to keep my computer’s time
synced.
#+BEGIN_SRC fish
sudo timedatectl set-ntp true
#+END_SRC

**** Acpilight
~acpilight~ is our utility managing the brightness of our screen. There
is actually no service to enable here, but we must ensure the user is
part of the ~video~ group to enable the user modifying the brightness of
our screen without using ~sudo~.
#+BEGIN_SRC fish
sudo usermod -aG video $USER
#+END_SRC

**** Docker
First, let’s activate Docker on startup.
#+BEGIN_SRC fish
printf "\n# Enabling and starting Docker ################################################\n\n"
sudo systemctl enable --now docker
#+END_SRC

Now, if we wish it, we can add ourselves to the =docker= group to avoid
typing =sudo= each time we call Docker or Docker Compose.
#+BEGIN_SRC fish
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. 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.
#+BEGIN_SRC fish
printf "\n# Enabling Emacs as user service ##############################################\n\n"
systemctl --user enable emacs
#+END_SRC

I don’t want to activate it immediately however, since the first
startup might require some interactivity with the main Emacs frame,
not with emacsclient. When Emacs will be ready, its service can be
started like so (command not tangled in the bootstrap):
#+begin_src fish :tangle no
systemctl --user start emacs
#+end_src

**** Mpd
Mpd will also use as a user service in order to get rid of some lines
of code in my configuration.
#+BEGIN_SRC fish
printf "\n# Enabling Mpd as a user service ##############################################\n\n"
mkdir -p ~/.config/mpd/playlists
systemctl --user enable --now mpd
#+END_SRC

**** NordVPN
Thanks to the AUR package ~nordvpn-bin~, I no longer have to manually
maintain my VPN connections with OpenVPN. However, it requires a
service 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 Wi-Fi as long as the 443 port is
available. Because yes, I do connect to a Wi-Fi that blocks some
important ports, such as the IMAP and SMTP ports. Thanks University of
Paris 8 for being SO paranoid.
#+BEGIN_SRC fish
nordvpn s protocol tcp
#+END_SRC

Note that this change in protocol is only valid when using the OpenVPN
technology. If we want to use the Wireguard technology through [[https://nordvpn.com/blog/nordlynx-protocol-wireguard/][Project
NordLynx]], this option will no longer be available. To set NordVPN to
use WireGuard, we can run this command (not tangled in the bootstrap).
#+begin_src fish :tangle no
nordvpn set technology NordLynx
#+end_src

Why WireGuard? Well, it can achieve better performances than OpenVPN
with physically nearby servers, and according to [[https://restoreprivacy.com/vpn/wireguard-vs-openvpn/][this article]] the
former can be more than half as fast as the latter. It is also much
more auditable than OpenVPN (only a few thousands lines of code
against some hundred of thousands). Oh, and WireGuard is part of the
Linux kernel since its version 5.6. And Windows’ since August 2021,
but I don’t really care about Windows.

*But*, WireGuard is less privacy-oriented than OpenVPN. So, if I ever
need to use my VPN for privacy reasons, I can simply revert to the
OpenVPN technology like shown with this command (not tangled in the
bootstrap):
#+begin_src fish :tangle no
nordvpn set technology OpenVPN
#+end_src

Finally, I want to be notified of NordVPN’s actions, and I want to be
able to use IPv6.
#+begin_src fish
nordvpn set notify enabled
nordvpn set ipv6 enabled
#+end_src

**** PipeWire
PipeWire is a replacement for PulseAudio, ALSA and the likes, and it
is /*much*/ better in terms of security and performance. However, unlike
PulseAudio, Pipewire is a user service that needs to be enabled per
user.
#+begin_src fish
systemctl --user enable --now pipewire-pulse.service
#+end_src

I also installed ~noise-suppression-for-voice~ which is a plugin usable
by PipeWire to remove all noise the microphone might record save for
the voice. It is damn effective, and it can be activated as a user
service! In fact, I have in my dotfiles the service saved, so let’s
activate it right away:
#+begin_src fish
systemctl --user enable --now pipewire-input-filter-chain.service
#+end_src

Just make sure afterwards the microphone is redirected to the
noise-canceling source. The same source should be your input device
where you want to use your microphone. The only downside is this is
only a mono input, but it shouldn’t matter for most people.

**** 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
whiptail --yesno 'Do you want to activate the ssh server?' 8 50
if test $status -eq 0
    printf "\n# Enabling ssh server #########################################################\n\n"
    sudo systemctl enable --now sshd
end
#+END_SRC

*** Symlink some system config files
Let’s symlink the ~plock~ script ([[file:bin.org::#Lock-635fcb38][source here]]) to ~/usr/bin~ so ~xss-lock~
can find it.
#+BEGIN_SRC fish
sudo ln -s ~/.local/bin/plock /usr/bin/plock
#+END_SRC

*** Install packages from git
Now, let’s install some packages from git directly.
#+BEGIN_SRC fish
mkdir -p ~/fromGIT
#+END_SRC

**** Reveal.JS
I sometimes use Reveal.JS to make presentations, and I set its
location in my [[file:emacs.org][Emacs config]] to be in =~/fromGIT=, so let’s clone it
there.
#+BEGIN_SRC fish
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, 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
#+END_SRC

**** Install some utilities
We’ll need some utilities when developing Rust from Emacs, namely
~rustfmt~. Let’s install it with ~cargo~.
#+BEGIN_SRC fish
printf "\n# Add rust utilities ##########################################################\n\n"
cargo install rustfmt
#+END_SRC

We will also need some components for development purposes.
#+NAME: rust-components-table
| Component | Why                                       |
|-----------+-------------------------------------------|
| rust-src  | Rust documentation in Emacs               |
| clippy    | A better version of cargo’s ~check~ command |

#+NAME: rust-components-gen
#+BEGIN_SRC emacs-lisp :var components=rust-components-table[,0]
(mapconcat (lambda (x) (format "rustup component add %s" x))
           components
           "\n")
#+END_SRC

#+RESULTS[2499c179aa97dc038832188f53dd855a23eba70c]: rust-components-gen
: rustup component add rust-src
: rustup component add clippy

Here is the code to do so:
#+BEGIN_SRC fish :noweb yes
<<rust-components-gen()>>
#+END_SRC

*** Set up our fish shell
The last thing we want to do is to set up our fish shell with some
extensions in order to improve the user experience.

**** Install ~fisher~
We will be using ~fisher~ as our extension manager for Fish. Let’s
install it.
#+BEGIN_SRC fish
printf "\n# Installing fisher ###########################################################\n\n"
curl -sL https://git.io/fisher | source && fisher install jorgebucaran/fisher
#+END_SRC

**** Install our extensions
I generally use the following extensions in my Fish shell.
#+NAME: fish-extensions-table
#+CAPTION: Fish extensions managed by Fisher
