# NAME
|
||||
|
||||
waybar - dwl tags module
|
||||
|
||||
# DESCRIPTION
|
||||
|
||||
The *tags* module displays the current state of tags in dwl.
|
||||
|
||||
# CONFIGURATION
|
||||
|
||||
Addressed by *dwl/tags*
|
||||
|
||||
*num-tags*: ++
|
||||
typeof: uint ++
|
||||
default: 9 ++
|
||||
The number of tags that should be displayed. Max 32.
|
||||
|
||||
*tag-labels*: ++
|
||||
typeof: array ++
|
||||
The label to display for each tag.
|
||||
|
||||
*disable-click*: ++
|
||||
typeof: bool ++
|
||||
default: false ++
|
||||
If set to false, you can left click to set focused tag. Right click to toggle tag focus. If set to true this behaviour is disabled.
|
||||
|
||||
# EXAMPLE
|
||||
|
||||
```
|
||||
"dwl/tags": {
|
||||
"num-tags": 5
|
||||
}
|
||||
```
|
||||
|
||||
# STYLE
|
||||
|
||||
- *#tags button*
|
||||
- *#tags button.occupied*
|
||||
- *#tags button.focused*
|
||||
- *#tags button.urgent*
|
||||
|
||||
Note that occupied/focused/urgent status may overlap. That is, a tag may be
|
||||
both occupied and focused at the same time.

||||

This protocol allows clients to get updates from dwl and vice versa.
|

Warning! The protocol described in this file is experimental and
|

backward incompatible changes may be made. Backward compatible
|

changes may be added together with the corresponding interface
|

version bump.
|

Backward incompatible changes are done by bumping the version
|

number in the protocol and interface names and resetting the
|

interface version. Once the protocol is to be declared stable,
|
||||
the 'z' prefix and the version number in the protocol and

interface names are removed and the interface version number is

reset.
