| ------ | ----- |

• implement master and stack layout like dwm in i3

• open first terminal in floating mode and default position

  you don't need to open the first terminal full screen. It will better if the terminal is display floating center on your screen when you open another window it will change to tilling mode .

  

• swap from any window to master with shorcut $mod+m

• move from any window to master with shorcut $mod+shift+m

  

• swallow instance

  this version is focus on i3 master and it is different to another swallow version because it will try to restore the original position when you move the swallow instance

Config

run script first and it will create a config file

$HOME/.config/i3/i3_master.ini

[config]
terminal = 'Alacritty'
screenWidth = 1300
screenHeight = 800
posX = 310
posY = 160
swallow = true

; different size between master and slave (unit : ppt)
masterSizePlus = 14  

; new instance on master will change to master
slaveStack = true  

Note: Use xdotool selectwindow getwindowgeometry change size and get a good postion on floating window

File manager with swallow

if your file manager is not working with the swallow function. You need to add scripts.

Example vifm

• Copy file swallow to folder $HOME/.config/vifm/scripts/.
• Edit /vifmrc

  filextype *.bmp,*.jpg,*.jpeg,*.png,*.gif,*.xpm
          \ {View in feh}
          \ swallow feh %f,
          \ {View in gpicview}
          \ gpicview %c,
          \ {View in shotwell}
          \ shotwell,
  

TODO

• Swallow when stack have 1 instance is bad

• Swallow use xprop and xdotool is slow.
