Layer-shell rules

Layer rules, similar to window rules, are a way to apply custom settings on layer-shells.

Just like window rules, they have two parts: the match part, and the properties part. Refer to the [window rules] page for information about what that is and match-all property.

For now, layer-shell rules are used to enable various effects on matched layer-shells

The match part

match-namespace

A list of Regular Expressions. They match onto the layer-shell's namespace. The namespace per protocol definition defines the purpose of a layer-shell, for example, notification, or volume-osd

Requires that the namespace has a match on only one regex from the given regexes.

on-output

Match on the output the layer-shell is opened on. Nothing fancy.

The following rule matches all layer-shells opened on a laptop's internal display

[[layer-rules]]
on-output = "eDP-1"
opacity = 0.5

Layer-shell properties

blur, shadow

These values take the same fields as their versions in the decorations configuration, however, they will override the decorations configuration with whatever fields you have provided.

By default, layer-shells have all of these disabled. Set disable=false to enable these effectss.

---

opacity

The opacity of the layer-shell, 0.0 is fully transparent, 1.0 is fully opaque.

---

corner-radius

The corner radius applied to the layer-shell's surface.
