Concepts

A desktop is (a pointer to) a tree. There are 1-10 (Roman Numbers) desktops (trees).
Monitor is just your real monitor, they divide the distribution of ten trees. Such as eDP-1 for first five tree (1-5), HDMI-1 for last five trees (5-10).
One leaf node holds one window (node ≈ window)

Manual mode

Manual Mode: User preselect the insertion point. If you don’t preselect, new node position will be determined by automatic scheme

Automatic Mode

Automatic Mode: The insertion position of new node determined by automatic scheme (longest_side, alternate, spiral) and initial polarity (first_child or second_child). bspc config automatic_scheme {longest_side,alternate,spiral}

  • Longest side scheme: the split direction was chosen based on dimensions of the tiling rectangle (whether height or width is longer) and the initial polarity.
    The following scenario set the initial polarity to second_child:

  • Alternate scheme: If parent is split horizontally, the child will be split vertically and vise versa.
  • Spiral scheme: It is best shows as image.
