A receptacle is an unfocusable empty leaf node.
Receptacles are used for building a tree without creating windows.
Example:
bspc node -i
bspc node @/ -p east -i
bspc node @/2 -p north -i
bspc rule -a Abc:abc -o node=@/1
bspc rule -a Ijk:ijk -o node=@/2/1
bspc rule -a Xyz:xyz -o node=@/2/2
Fixes#259.
It is now easy to access any attribute by piping the output of
`query -T` to a JSON extractor/filter.
E.g.:
bspc query -T -d DESKTOP_SEL | jq -r .layout
And it also makes `restore -T` more robust.
The last desktop and monitor are now deduced from the history.
The stacking order is now independent from the history of the focused
nodes: this prevents hacks on both sides.
All windows are now considered in the stacking algorithm: it prevents
tiled windows from one monitor to appear above the floating windows of
another monitor.
Transfered windows are stacked below the windows of the same kind.
The above setting's purpose was to replace `wmname` but it appears that
it can't be done without violating the EWMH standards and creating bad
side effects.
The new message syntax:
- Provides 10 commands instead of 60.
- Allows multiple actions to be applied in one call.
The client now returns an non zero exit code when a message fails.
The `is_adjacent` function now handles vacant nodes.
The aforementioned setting, when set, makes the focus movements based on
the distances between the window sides.
The `{prev,next}_leaf` functions were taught not to climb above their
roofs.
