Settings for i3-gaps

  # Set inner/outer gaps
  gaps inner 10
  gaps outer -2

  # Additionally, you can issue commands with the following syntax. This is useful to bind keys to changing the gap size.
  # gaps inner|outer current|all set|plus|minus <px>
  # gaps inner all set 10
  # gaps outer all plus 5

  # Smart gaps (gaps used if only more than one container on the workspace)
  # smart_gaps on

  # Smart borders (draw borders around container only if it is not the only container on this workspace)
  # on|no_gaps (on=always activate and no_gaps=only activate if the gap size to the edge of the screen is 0)
  # smart_borders on

  # Press $mod+Shift+g to enter the gap mode. Choose o or i for modifying outer/inner gaps. Press one of + / - (in-/decrement for current workspace) or 0 (remove gaps for current workspace). If you also press Shift with these keys, the change will be global for all workspaces.
  set $mode_gaps Gaps: (o) outer, (i) inner
  set $mode_gaps_outer Outer Gaps: +|-|0 (local), Shift + +|-|0 (global)
  set $mode_gaps_inner Inner Gaps: +|-|0 (local), Shift + +|-|0 (global)
  bindsym $mod+Shift+g mode "$mode_gaps"

  mode "$mode_gaps" {
    bindsym o      mode "$mode_gaps_outer"
    bindsym i      mode "$mode_gaps_inner"
    bindsym Return mode "default"
    bindsym Escape mode "default"
  }
  mode "$mode_gaps_inner" {
    bindsym plus  gaps inner current plus 5
    bindsym minus gaps inner current minus 5

    bindsym 0     gaps inner current set 0

    bindsym Shift+plus  gaps inner all plus 5
    bindsym Shift+minus gaps inner all minus 5
    bindsym Shift+0     gaps inner all set 0

    bindsym Return mode "default"
    bindsym Escape mode "default"
  }
  mode "$mode_gaps_outer" {
    bindsym plus  gaps outer current plus 5
    bindsym minus gaps outer current minus 5
    bindsym 0     gaps outer current set 0

    bindsym Shift+plus  gaps outer all plus 5
    bindsym Shift+minus gaps outer all minus 5
    bindsym Shift+0     gaps outer all set 0

    bindsym Return mode "default"
    bindsym Escape mode "default"

Workspace names

To display names or symbols instead of plain workspace numbers you can use something like: set $ws1 1:mail and set $ws2 2:.

  set $ws1 1
  set $ws2 2
  set $ws3 3
  set $ws4 4
  set $ws5 5
  set $ws6 6
  set $ws7 7
  set $ws8 8

Use Mouse+$mod to drag floating windows

  floating_modifier $mod

Back and Forth

  workspace_auto_back_and_forth yes

Application Specific

Open applications on specific workspaces

  # Matlab Figures
  assign[title="^Fig"] $ws6
  for_window [title="^Fig"] layout tabbed
  assign[title="^HG_Peer"] $ws6 # Name of window when export figure with matlab

Open specific applications in floating mode

  for_window [title="File Transfer*"] floating enable
  for_window [class="GParted"] floating enable border normal
  for_window [title="i3_help"] floating enable sticky enable border normal
  for_window [class="Lightdm-settings"] floating enable
  for_window [class="Lxappearance"] floating enable sticky enable border normal
  for_window [class="Manjaro Settings Manager"] floating enable border normal
  for_window [class="Pamac-manager"] floating enable

  for_window [title="^Documentation -"] floating enable border normal
  for_window [class="Yad"] floating enable
  for_window [title="Bluetooth Devices"] floating enable
  for_window [title="Simulink Library Browser"] floating enable

Scratchpad

  # move the currently focused window to the scratchpad
  bindsym $mod+Shift+BackSpace move scratchpad

  # Show the next scratchpad window or hide the focused scratchpad window.
  # If there are multiple scratchpad windows, this command cycles through them.
  bindsym $mod+BackSpace scratchpad show

Run Polybar and SXHKD

  exec_always --no-startup-id $HOME/.config/polybar/scripts/launch.sh
  exec_always --no-startup-id sxhkd -m 1 -c ~/.config/sxhkd/sxhkdrc.i3
