Dwindle is a BSPWM-like layout, where every window on a workspace is a member of a binary tree.

Quirks

Dwindle splits are NOT PERMANENT. The split is determined dynamically with the W/H ratio of the parent node. If W > H, it's side-by-side. If H > W, it's top-and-bottom. You can make them permanent by enabling preserve_split.

Config

category name: dwindle

name	description	type	default
pseudotile	enable pseudotiling. Pseudotiled windows retain their floating size when tiled.	bool	false
force_split	0 -> split follows mouse, 1 -> always split to the left (new = left or top) 2 -> always split to the right (new = right or bottom)	int	0
preserve_split	if enabled, the split (side/top) will not change regardless of what happens to the container.	bool	false
smart_split	if enabled, allows a more precise control over the window split direction based on the cursor's position. The window is conceptually divided into four triangles, and cursor's triangle determines the split direction. This feature also turns on preserve_split.	bool	false
smart_resizing	if enabled, resizing direction will be determined by the mouse's position on the window (nearest to which corner). Else, it is based on the window's tiling position.	bool	true
permanent_direction_override	if enabled, makes the preselect direction persist until either this mode is turned off, another direction is specified, or a non-direction is specified (anything other than l,r,u/t,d/b)	bool	false
special_scale_factor	0 - 1 -> specifies the scale factor of windows on the special workspace	float	1
split_width_multiplier	specifies the auto-split width multiplier	float	1.0
no_gaps_when_only	whether to apply gaps when there is only one window on a workspace, aka. smart gaps. (default: disabled - 0) no border - 1, with border - 2	int	0
use_active_for_splits	whether to prefer the active window or the mouse position for splits	bool	true
default_split_ratio	the default split ratio on window open. 1 means even 50/50 split. 0.1 - 1.9	float	1.0

pseudo	toggles the focused window's pseudo mode	none

Layout messages

Dispatcher layoutmsg params:

param	description	args
togglesplit	toggles the split (top/side) of the current window. preserve_split must be enabled for toggling to work.	none
preselect	A onetime override for the split direction. (valid for the next window to be opened, only works on tiled windows)	direction

e.g.:

bind = SUPER, A, layoutmsg, preselect l
