Bars and layouts

A bar layout is an entry in the [[bar.layout]] array. Each entry targets a monitor (or all of them) and describes what the bar renders there. Fields:

Field	Role
monitor	Connector name like "DP-1", or "*" to match any monitor without a more specific entry
left, center, right	Module lists for the three sections
extends	Optional. Inherit from another entry by its monitor value
show	Optional. Set to false to hide the bar on that monitor

Inside left, center, and right, a module slot accepts three shapes, mixable within the same section:

Shape	TOML
Plain module	"clock"
Classed module	{ module = "clock", class = "primary" }
Named group	{ name = "status", modules = ["battery", "network"] }

See BarLayout for the full variant examples and /config/bar for spacing, colors, and button styling.

Minimal layout

One entry matching every monitor, filled with built-in modules:

[[bar.layout]]
monitor = "*"
left = ["dashboard"]
center = ["clock"]
right = ["battery", "network", "volume", "systray"]

monitor takes a connector name like "DP-1" or "HDMI-A-1", or "*" to match any monitor without a more specific entry.

Per-monitor overrides

A second entry with extends inherits from another layout. Any section the child omits (or leaves as an empty list) is filled in from the parent; any section the child sets replaces the parent's.

[[bar.layout]]
monitor = "HDMI-1"
left = ["dashboard"]
center = ["clock"]
right = ["battery", "network", "volume", "systray"]

[[bar.layout]]
monitor = "*"
extends = "HDMI-1"
right = ["volume", "systray"]

On *, left and center come from the "HDMI-1" layout; right is this entry's list. extends can point at any other monitor value, not only "HDMI-1".

Groups and classes

A group renders its modules inside a shared GTK container. The group's name becomes the container's CSS ID, addressable as #name in a stylesheet (custom CSS coming soon). Use groups when several modules should share a visual container (padding, background, border radius) targetable by one selector.

A class attaches to a single module instance. Use it when the same module appears twice on a bar and each instance needs different styling, or when one instance should diverge from the module's default look.

[[bar.layout]]
monitor = "DP-1"
left = ["dashboard"]
center = [{ module = "clock", class = "primary" }]
right = [{ name = "status", modules = ["battery", "network", "volume"] }]

Custom modules slot in the same way, referenced as custom-<id> where <id> matches an entry in [[modules.custom]]. See custom modules.

Hiding a bar

Set show = false on an entry to hide the bar on that monitor. No other fields are required.

[[bar.layout]]
monitor = "HDMI-2"
show = false
