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
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	0.8
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.	bool	false
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

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
