# Simple PulseAudio volume monitor for xmobar

This little monitor is my attempt to read the current volume and mute setting
of the default sink from PulseAudio and make it accessible to xmobar:

```haskell
Config { commands = [ Run CommandReader "puvol-cont" "Vol" ]
       , template = " %Vol% "
```

If it is called as `puvol-cont` it will wait for updates from PulseAudio, read
the current value of the mute and volume states and write an output line to
stdout (`🔇` or volume percentage).

## Installation

```shell
go install kesim.org/puvol
```

For the continous mode you have to copy or add an symbolic link with name `puvol-cont`:

```shell
cd /path/to/bin/dir
ln -s puvol puvol-cont
```
