       yambar-modules - configuration file

DESCRIPTION

Modules are what monitors your system and provides data for the status bar.

All modules expose their data through tags. Each tag has a name, type and value. The name and type is
fixed, while the value typically changes over time. See yambar-tags(5).

The tags are rendered by particles. Each particle has its own way of representing tag values. The
simplest one is the string particle, which renders a text representation of the tag value. See yambar-
particles(5).

Note that all the examples showed below have been kept simple. Here are a couple of tips that will
improve the looks:

Use list particles to change font and/or color
The string particle, for example, cannot change font or colors in the middle of its string. To do this,
you need to wrap multiple string particles in a list particle.

This can be useful if you want to use an icon font for a glyph since the default fallback fonts provided
by fontconfig may not favor your icon font.

Also remember there is a short version for lists (see yambar-particles(5))

For example, to render backlight as " 20%", you could use:

content:
- string:
font: Font Awesome 6 Free:style=solid:pixelsize=14
text: 
- string:
font: Adobe Helvetica:pixelsize=12
text: "{percent}%"

Use map particles to handle 'state'
Several modules have a state tag that can be used to render different particles depending on the module's
state.

For example, you might want different things to be shown for a network interface that is down or up. You
could further differentiate between an up interface that has or has not an IP address assigned to it.

Below is an example, where a wired connection is not renderer at all when disconnected.

When connected, it is rendered in the default text color if it is up and also has an IPv4 address. If it
is up, but does not have an IPv4 address, it is rendered in a semi-transparent white color.

Finally, if it is down, or in any other unknown state, it is rendered in red.

content:
map:
conditions:
~carrier: {empty: {}}
carrier:
map:
default: {string: {text: , font: *awesome, foreground: ffffff66}}
conditions:
state == up:
map:
default: {string: {text: , font: *awesome}}
conditions:
ipv4 == "": {string: {text: , font: *awesome, foreground: ffffff66}}

Use yaml anchors
You often end up using the same definitions in a lot of places. This is particular true for fonts. But it
can also be true when mapping state.

In these cases, you can define an anchor point, either at top-level, or in a module's anchors attribute:

awesome: &awesome Font Awesome 6 Free:style=solid:pixelsize=14

Then reference it in your particle definitions:

content:
string: {text: , font: *awesome}

GENERIC CONFIGURATION

       Each  module defines its own configuration format. However, the following attributes are supported by all
       modules:
