 =i3= is  a window manager for  GNU/Linux which automatically tiles  windows in
  workspaces. This configuration was ade to automatically handle some tasks such
  as  which  software allowed  where,  autostart,  and launching  software  with
  shortcuts.

  It  is  to be  noted  I  am using  [[https://github.com/Airblader/i3][Airblader’s  fork  of i3]], =i3-gaps=.  Some
  configuration will not work with =i3=.

   The first I  do is declaring the modifier  key and the alt key  —I don’t find
   the names =Mod1=  and =Mod4= to be  explicit enough. This will  map =$mod= to
   the Super  key (or as some  people unfortunately call it,  the /Windows/ key)
   and =$alt= to  the Alt key.

   Let’s  also  bind the =$up=, =$down=, =$left=  and =$right=  variables  to
   respectively the up,  down, left, and right arrows on  the keyboard. Why bind
   them to  variables? If I  ever want  to modify the  arrow keys to  some other
   keys, like =é=, =a=, =u=, and =i= (the  equivalent of =wqsd= on  the bépo
   layout) or =c=, =t=, =s=, and =r= (the  equivalent of =hjkl= on  the bépo
   layout), I will just have to modify these four lines.

   I’ll also set the =$term= variable. A lot of shortcuts in  my i3 config rely
   on the terminal emulator itself to  launch commands in the terminal, and thus
   call the terminal itself. If I ever  need to move from my current terminal, I
   will just have to change the name of the executable here.

   Now comes  the font for the  window tiles. Honestly, this  setting is useless
   since we do not see it, but let’s set it anyway.

** Floating windows
   :PROPERTIES:
   :CUSTOM_ID: h-944b65df-c5c6-4f9a-9824-08e063ba20dd
   :END:
   Floating  windows are  windows that  are not  tiled with  other windows,  but
   rather are free to go anywhere on your screen, with any size. A bit like what
   you would get with any other non-tiling window manager or desktop environment
   (though most of them support minimal tiling features).

   Let’s declare our floading modyfier. With floating windows, you can move them
   around by clicking on the window’s borders;  but since we don’t have any with
   this  config, we  will  have instead  to press  the  floating modifier  while
   clicking on the window (anywhere on the window is fine) to move them around.

   Here is the configuration:
   #+BEGIN_SRC conf
   floating_modifier $mod
   #+END_SRC

* i3 global settings
  :PROPERTIES:
  :CUSTOM_ID: h-d9bc7729-d325-4071-8ad9-043ea5b80430
  :END:
  Some settings affect i3 globally, such as its aspect or how it handles the
  mouse. Hence, here are some settings I set in my configuration.

** Mouse settings
   :PROPERTIES:
   :CUSTOM_ID: h-3ab33a7a-6a31-4a76-a59f-baf7913279b4
   :END:
   First of all, I  do not want i3 to warp my mouse  each time I change windows;
   my mouse stays where it is.
   #+BEGIN_SRC conf
   mouse_warping none
   #+END_SRC
   I also to not  want the window focus to follow my  mouse, because sometimes I
   will just knock  my physical mouse out of  the way of my hand, and  when I do
   that the software  mouse will most likely  end up in another window  I do not
   want to focus.
   #+BEGIN_SRC conf
     focus_follows_mouse no
   #+END_SRC

** Popup handling
   :PROPERTIES:
   :CUSTOM_ID: h-64ef3c3b-bc70-4839-9bee-e113df4ee848
   :END:
   While in  fullscreen, some software might  generate a popup. In  that case, I
   want to  be aware of  that, and  any popup will  make me leave  fullscreen in
   order to be presented with said popup.
   #+BEGIN_SRC conf
   popup_during_fullscreen leave_fullscreen
   #+END_SRC

** Behavior of workspace changes
   :PROPERTIES:
   :CUSTOM_ID: h-192d7269-eba7-4684-80c7-cb01c32c5f38
   :END:
   When changing workspace as  described below, we often want to  go back to the
   previous workspace we were working on,  but we might not remember immediately
   which  one it  was, or  we might  still have  our fingers  ready to  fire the
   shortcut which made us make the first workspace change. Hence, if we type the
   same workspace  change shortcut, instead  of doing  nothing it will  bring us
   back to the previous workspace we were on.
   #+BEGIN_SRC conf
   workspace_auto_back_and_forth yes
   #+END_SRC

** Gaps and window appearance
   :PROPERTIES:
   :CUSTOM_ID: h-52a82bb4-42b0-4740-aae6-79636072dc62
   :END:
   As mentioned in at the beginning of  this document, I am using i3-gaps, which
   brings spacing (gaps) between windows to i3.

   First, I want space around my  windows only when there are several containers
   on the same screen, otherwise they will be maximized.
   #+BEGIN_SRC conf
     smart_gaps on
   #+END_SRC

   I also  do not  want to  see any  window border,  so I  will be  turning this
   setting off.
   #+BEGIN_SRC conf
     smart_borders on
   #+END_SRC

   By the way, the default border is invisible, since it is zero pixels wide.
   #+BEGIN_SRC conf
   default_border pixel 0
   #+END_SRC

   Then comes the size of these gaps. I made the outer gap negative so the space
   between my  windows and  the border  of my  screens is  smaller than  the gap
   between my containers.
   #+BEGIN_SRC conf
     gaps inner 20
     gaps outer -10
   #+END_SRC

   Some  parameters are  also available  when it  comes to  the colors  i3 uses.
   Honestly, we  won’t see these colors  much, so let’s simply  keep the default
   values.
   #+BEGIN_SRC conf
     set_from_resource $fg i3wm.color7 #f0f0f0
     set_from_resource $bg i3wm.color2 #f0f0f0

     # class                 border  backgr. text indicator child_border
     client.focused          $bg     $bg     $fg  $bg       $bg
     client.focused_inactive $bg     $bg     $fg  $bg       $bg
     client.unfocused        $bg     $bg     $fg  $bg       $bg
     client.urgent           $bg     $bg     $fg  $bg       $bg
     client.placeholder      $bg     $bg     $fg  $bg       $bg

* Assigning windows to workspaces
  :PROPERTIES:
  :CUSTOM_ID: h-21870449-7730-4164-8add-167cb4e75218
  :END:
  I decided to bind some windows to some workspaces in order to have a better
  organization of my desktop.

  #+NAME: assignment-table
  | Application | Class       | Workspace |
  |-------------+-------------+-----------|
  | Emacs       | Emacs       |         2 |
  | Chromium    | Chromium    |         3 |
  | Firefox     | firefox     |         3 |
  | Nemo        | Nemo        |         4 |
  | Wonderdraft | Godot       |         5 |
  | Gimp        | Gimp*       |         6 |
  | Gnome Boxes | gnome-boxes |         8 |
  | Steam       | Steam       |         9 |
  | Discord     | discord     |        10 |

  The class table is used in the assignment in the i3 config file. For instance,
  Gimp’s assignment will look like this:
  #+BEGIN_SRC conf :tangle no
    assign [class="Gimp*"] 6
  #+END_SRC

  #+NAME: generate-workspaces
  #+BEGIN_SRC emacs-lisp :var workspaces=assignment-table :cache yes
    (mapconcat (lambda (x) (format "assign [class=\"%s\"] %s" (cadr x) (caddr x)))
               workspaces
               "\n")
  #+END_SRC

  #+RESULTS[0995341b013e50227edf78257ab502e46a30bc9a]: generate-workspaces
  : assign [class="Emacs"] 2
  : assign [class="Chromium"] 3
  : assign [class="firefox"] 3
  : assign [class="Nemo"] 4
  : assign [class="Godot"] 5
  : assign [class="Gimp*"] 6
  : assign [class="gnome-boxes"] 8
  : assign [class="Steam"] 9
  : assign [class="discord"] 10

  Here is the configuration:
  #+BEGIN_SRC conf :noweb yes
  <<generate-workspaces()>>
  #+END_SRC

  And although  this is not  specifically assigning a  window to a  workspace, I
  also want to have the tenth workspace  assigned to a specific output in case I
  have  two screens  — and  since this  is the  case when  I am  using only  one
  computer,  Marpa, I  will  be using  some  EmacsLisp in  order  to generate  a
  different configuration file  from this org file depending on  the name of the
  machine.
  #+NAME: ws10-output-edp1
  #+BEGIN_SRC emacs-lisp
    (if (string= system-name "Marpa")
        "workspace 10 output eDP-1"
      "")
  #+END_SRC

  Now I’ll call the above code as a noweb reference that should be executed.
  #+BEGIN_SRC conf
    <<ws10-output-edp1()>>
  #+END_SRC

* Shortcuts
  :PROPERTIES:
  :CUSTOM_ID: h-b364743d-2ff0-4548-805e-9a9e6efdaddd
  :END:
  I use *A LOT*  of shortcuts when it comes to my workflow.  Like, all the time.
  So, expect  this chapter to be  a bit long, and  I’ll try to make  it readable
  still.

  Shortcuts are set like so:
  #+BEGIN_SRC conf :tangle no
  bindsym shortcut command
  #+END_SRC

  #+NAME: generate-shortcuts
  #+BEGIN_SRC emacs-lisp :exports none :var table=[] :tangle no
    (mapconcat (lambda (x) (format "bindsym %s %s" (car x) (cadr x)))
               table
               "\n")
  #+END_SRC

** Terminal shortcuts
   :PROPERTIES:
   :CUSTOM_ID: h-7dbb2902-29ca-48a7-bfa3-a831b72549f3
   :END:
   I have a couple of shortcuts which  are related to my terminal. For instance,
 ~$mod+Return~ opens a regular terminal  instance while ~$mod+$alt+M~ opens an
   SSH instance on my Mila host.
   #+NAME: terminal-shortcuts
   | shortcut          | command              | What it does                                     |
   |-------------------+----------------------+--------------------------------------------------|

   | $mod+$alt+Return  | split h;; exec $term | Opens a terminal console below the current one   |
   | $mod+Shift+Return | split v;; exec $term | Opens a terminal on the right of the current one |
   | $mod+$alt+m       | exec $term ssh Mila  | Opens an SSH instance in my Mila host            |
   | $mod+$alt+n       | exec $term ssh Naro  | Opens an SSH instance in my Naro host            |
   | $mod+Shift+h      | exec $term htop      | Opens a terminal with ~htop~                     |

   Here is the configuration:

   #+END_SRC

** i3 shortcuts
   :PROPERTIES:
   :CUSTOM_ID: h-22855720-e388-463a-a941-fa8bad2c89c0
   :END:
   A couple of shortcuts are dedicated to i3 itself.
   #+NAME: i3-sh
   | shortcut     | command                         | what it does                     |

   And  although this  is not  really an  i3  shortcut per  se, I  add here  the
   shortcut for  launching pywal,  which will  set one of  my wallpapers  as the
   wallpaper and will generate my system’s color configuration from it.
   #+NAME: wal-sh
   | shortcut | command      | what it does                                                 |
   |----------+--------------+--------------------------------------------------------------|
   | $mod+w   | exec $walset | Set a random wallpaper and generates a color profile from it |

   We also  have some shortcuts  to lock our  screen, sleep, hibernate  and shut
   down our computer.
   #+NAME: computer-sh
   | shortcut      | command                    | what it does           |

   | $mod+$alt+h   | exec "systemctl suspend"   | Suspend the computer   |
   | $mod+Ctrl+h   | exec "systemctl hibernate" | Hibernate the computer |
   | $mod+Shift+F4 | exec poweroff              | Power off the computer |

    :CUSTOM_ID: h-e4e57280-91d2-4140-9295-7117cf85ed04
    :END:
    It is possible to indicate to i3 how windows interact with one another, and
    especially how they are organized by spawning new windows either to the
    right or below the current window.
    #+NAME: split-win-sh

*** Focus windows
    :PROPERTIES:
    :CUSTOM_ID: h-570eda16-ed4b-4684-a54f-9202e8409ed9
    :END:
    To change window focus, you can use one of the following shortcuts:
    #+NAME: window-focus-sh
    | shortcut    | command     | what it does                              |

    :END:
    Just like windows,  it is also possible to change  focus between workspaces,
    because let’s be  honest, most people won’t have ten  screens to display all
    ten workspaces at the same time, and frankly that would be impractical.

    To move  containers between  the available screens,  you have  the following
    shortcuts:
    #+NAME: containers-move-sh
    | shortcut         | command                        | what it does                                               |

    You can also send containers to other workspaces by their number.

    It is also possible to move workspaces. The related shortcuts available are
    the following:

    #+NAME: workspace-move-sh
    | shortcut               | command                        | what it does                                               |

*** Close windows
    :PROPERTIES:
    :CUSTOM_ID: h-05e30514-86c2-42af-8712-dc0bdc30cd3d
    :END:
    To close windows, we have two main shortcuts: Alt+F4 and mod+q. The first
    one is here due to habits, but I don’t really use it anymore due to my main
    keyboard which doesn’t have any easy access to the functions keys, hence
    mod+q.
    #+NAME: close-win-sh
    | shortcut | command | what it does            |
    |----------+---------+-------------------------|
    | $mod+q   | kill    | kill the current window |
    | $alt+F4  | kill    | kill the current window |

    Here is the configuration:
    #+BEGIN_SRC conf
    <<generate-shortcuts(table=close-win-sh)>>
    #+END_SRC

*** Manage the size of the current window
    :PROPERTIES:
    :CUSTOM_ID: h-f730b4c8-8602-426b-a2bc-7dfbbe42e711
    :END:
    It is  possible to change the  size of the current  window, even if it  is a
    floating one.  The first shortcut  that might  interest you is  $mod+f which
    switches your current window to fullscreen. But to resize a window, you will
    need to enter the ~resize~ mode.
    #+NAME: size-win-sh
    | shortcut | command           | what it does                                      |
    |----------+-------------------+---------------------------------------------------|
    | $mod+f   | fullscreen toggle | Puts the current window in fullscreen or exits it |
    | $mod+r   | mode "resize"     | Enter resize mode                                 |

    When it comes to modes, they are defined as follows:
    #+BEGIN_SRC conf :tangle no
      mode "nameofyourmode" {
          here go your shortcuts
      }
    #+END_SRC

    So, all the following shortcuts will  be inserted in a mode called ~resize~.
    Note that not only are the resizing  shortcuts bound to the arrow keys, they
    are also bound to ~ctsr~, which is the bépo equivalent of ~hjkl~.
    #+NAME: resize-win-sh
    | shortcut | command                             | what it does                              |
    |----------+-------------------------------------+-------------------------------------------|
    | $right   | resize grow width 20 px or 10 ppt   | Increase the width of the current window  |
    | r        | resize grow width 20 px or 10 ppt   | Increase the width of the current window  |
    | $left    | resize shrink width 10 px or 5 ppt  | Decrease the width of the current window  |
    | c        | resize shrink width 10 px or 5 ppt  | Decrease the width of the current window  |
    | $down    | resize grow height 10 px or 5 ppt   | Increase the height of the current window |
    | t        | resize grow height 10 px or 5 ppt   | Increase the height of the current window |
    | $up      | resize shrink height 10 px or 5 ppt | Decrease the height of the current window |
    | s        | resize shrink height 10 px or 5 ppt | Decrease the height of the current window |
    | Return   | mode "default"                      | Return to the default mode                |
    | Escape   | mode "default"                      | Return to the default mode                |
    If  you prefer,  you  can think  of  these shortcuts  not  as increasing  or
    decreasing the width or height of the  current window, but rather as how the
    bottom or right limit of the windows  will be moved relative to the top left
    corner.

    Here is the configuration:
    #+BEGIN_SRC conf
      <<generate-shortcuts(table=size-win-sh)>>
      mode "resize" {
          <<generate-shortcuts(table=resize-win-sh)>>
      }
    #+END_SRC

*** Manage floating windows

    :CUSTOM_ID: h-08f738b7-3369-4dbd-98e6-df6d6aa381b8
    :END:
    As said above,  your windows can be floating windows  instead of being tiled
    like they are by default. For this too we have a couple of shortcuts:
    #+NAME: float-win-sh
    | shortcut         | command              | what it does                                         |
    |------------------+----------------------+------------------------------------------------------|
    | $mod+Shift+space | floating toggle      | Toggles the window between tiled and floating mode   |
    | $mod+space       | focus mode_toggle    | Toggles the focus between tiled and floating windows |
    | $mod+Ctrl+c      | move position center | Centers the focused floating window                  |
    If you  want to move around  your floating window,  you can do it  with your
    mouse while holding down the floating modifier declared [[#h-944b65df-c5c6-4f9a-9824-08e063ba20dd][here]].

    Here is the configuration:
    #+BEGIN_SRC conf
    <<generate-shortcuts(table=float-win-sh)>>
    #+END_SRC

*** Scratchpad and window display
    :PROPERTIES:
    :CUSTOM_ID: h-92e67454-eccb-4465-8d47-947a1a5d55d9
    :END:
    You can think  of i3’s scratchpad as  some sort of extra  workspace in which
    you can hide your  windows you are not using, or as if  you want to reduce a
    window to the taskbar of other  window managers or desktop environments. You
    have basically two shortcuts for the  scratchpad: one that sends the current
    window to  the scratchpad, and one  that cicles through the  windows sent to
    the scratchpad and shows them to you  sequencially. If you go through all of
    them, they will be hidden again. You  can get a window out of the scratchpad
    by tiling it to the current workspace with the shortcut described above.

    You also have  the possibility of making a floating  window a sticky window.
    This means not only  will it show on all workspaces, it will  also be on top
    of every other window.  It can be useful if you have some  notes you want to
    keep an eye on for instance.
    #+NAME: scratchpad-sh
    | shortcut     | command         | what it does                                         |
    |--------------+-----------------+------------------------------------------------------|
    | $mod+Shift+s | move scratchpad | Sends the current window to the scratchpad           |
    | $mod+s       | scratchpad show | Shows and cycles through windows from the scratchpad |
    | $mod+Ctrl+s  | sticky toggle   | Toggles sticky mode on current window                |

    Here is the configuration:
    #+BEGIN_SRC conf

    It is possible to dynamically change the gaps between containers if we want
    to change a bit the appearance of i3. For that, we obviously have some
    shortcuts.
    #+NAME: gaps-resize-sh
    | shortcut          | command                                       | what it does                 |
    |-------------------+-----------------------------------------------+------------------------------|
    | $mod+g            | gaps inner current plus 5                     | Increase the inner gap size  |
    | $mod+Shift+g      | gaps inner current minus 5                    | Decrease the inner gap size  |
    | $mod+Ctrl+g       | gaps outer current plus 5                     | Increase the outer gap size |
    | $mod+Ctrl+Shift+g | gaps outer current minus 5                    | Decrease the outer gap size |
    | $mod+$alt+g       | gaps inner all set 20; gaps outer all set -10 | Reset gaps                   |

    Here is the corresponding configuration:

   A  big part  of  my i3  shortcuts  though are  related  to launching  various
   software. I’ll try to sort them by category  here, but do take a look even at
   categories which  you might not  be interested  in, they might  actually have
   something useful for you.

    Here we  have four commands  for managing  our screen’s brightness  (this is
    useful for laptops, not so much with desktops), and two of them are actually
    duplicates of the other two in case  a laptop doesn’t have dedicated keys or
    we are using a keyboard which doesn’t provide them.
    #+NAME: brightness-sh

    Some shortcuts are  dedicated to media control, especially when  it comes to
    controlling music.  All of these  media control  shortcuts will be  calls to
 ~mpc~ which will in turn send commands to ~mpd~, which is the music server I
    use on my computers.
    #+NAME: media-sh

    We also  have two shortcuts for  launching ncmpcpp, my mpd  frontend, either
    with the playlist open by default, or the visualizes open.

    | $mod+Shift+v | exec $term ncmpcpp -qs visualizer | Launch ncmpcpp’s visualizer      |

    We also  have more  general shortcuts,  like how  to manipulate  the general
    volume level.
    #+NAME: volume-sh
    | shortcut             | command                                | what it does         |

    And last  but not least, I  have some other shortcuts  for various software,
    some of them which I use quite a lot like the shortcut for launching Emacs.
    #+NAME: misc-sh
    | shortcut    | command          | what it does                    |

    | $mod+e      | exec $ec         | Launch Emacs client             |

    #+END_SRC

*** Screen management

    :CUSTOM_ID: h-ea5bab8e-cb7c-4ccb-8594-c2c319d1f7eb
    :END:
    Additionally,  we have  a shortcut  for  entering presentation  mode on  the
    additional screen of the computer; on my main computer, Mila, the additional
    screen is  HDMI-1, while it  is VGA1 on my  travel laptop. We’ll use some
    Emacs Lisp to determine on the configuration file export which screens names
    to use.
    #+NAME: hostname-screen-management
    #+BEGIN_SRC emacs-lisp
      (cond ((string= system-name "Marpa") "bindsym $mod+Ctrl+p xrandr --output HDMI-1 --mode 1024x768 --right-of eDP-1")
            ((string= system-name "gampo") "bindsym $mod+Ctrl+p xrandr --output VGA1 --mode 1024x768 --right-of LVDS1"))
    #+END_SRC

    Now, we just have to call this Emacs Lisp code as a noweb reference and
    execute it.
    #+BEGIN_SRC conf :noweb yes
      <<hostname-screen-management()>>
    #+END_SRC

  My  travel  laptop  has  a  fingerprint   reader  which  can  be  used  as  an
  authentification  method when  the root  password is  asked. Let’s  launch our
