# Volumearc widget

Almost the same as [volumebar widget](https://github.com/streetturtle/awesome-wm-widgets/tree/master/volumebar-widget), but using [arcchart](https://awesomewm.org/doc/api/classes/wibox.container.arcchart.html):

Supports 
 - scroll up - increase volume, 
 - scroll down - decrease volume, 
 - left click - mute/unmute.

## Customization

It is possible to customize widget by providing a table with all or some of the following config parameters:

| Name | Default | Description |
|---|---|---|
| `main_color` | `beautiful.fg_normal` | Color of the arc |
| `bg_color` | `#ffffff11` | Color of the arc's background |
| `mute_color` | `beautiful.fg_urgent` | Color of the arc when mute |
| `path_to_icon` | /usr/share/icons/Arc/status/symbolic/audio-volume-muted-symbolic.svg | Path to the icon |
| `thickness` | 2 | The arc thickness |
| `height` | `beautiful.fg_normal` | Widget height |
| `timeout` | 1 | How often in seconds the widget refreshes |
| `get_volume_cmd` | `amixer -D pulse sget Master` | Get current volume level |
| `inc_volume_cmd` | `amixer -D pulse sset Master 5%+` | Increase volume level |
| `dec_volume_cmd` | `amixer -D pulse sset Master 5%-` | Decrease volume level |
| `tog_volume_cmd` | `amixer -D pulse sset Master toggle` | Mute / unmute |
| `button_press` | `function(_, _, _, button) <sane default logic> end` | Overwrite the 'button\_press' signal for this widget |

### Example:

```lua
volumearc_widget({
    main_color = '#af13f7',
    mute_color = '#ff0000',
    thickness = 5,
    height = 25,
    button_press = function(_, _, _, button)   -- Overwrites the button press behaviour to open pavucontrol when clicked
        if (button == 1) then awful.spawn('pavucontrol --tab=3', false)
        end
    end
})
```

The config above results in the following widget:
