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.
Along the way, we also fixed the handling of the `*_padding`,
`window_gap` and `border_width` settings. The previous behavior was the
result of a bad decision (9fed780), as a response to #141. Many issues
followed: #143, #158, #260, etc. We now handle those settings as
intuitively as possible.
We also fixed a potential segfault in `cmd_node`, triggered by `bspc
node -d`[sic].
Fixes#402#252.
There's no constraints on desktop and monitor names, therefore, using a
desktop or monitor name as descriptor is ambiguous.
We put an end to this ambiguity by introducing desktop and monitor IDs.
`bspc query -{M,D}` now yields IDs instead of names.
Fixes#397.
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.
