# Volume widget
|
||
|
|
|
||
|
|
Volume widget based on [amixer](https://linux.die.net/man/1/amixer) (is used for controlling the audio volume) and [pacmd](https://linux.die.net/man/1/pacmd) (is used for selecting a sink/source). Also, the widget provides an easy way to customize how it looks, following types are supported out-of-the-box:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
From left to right: `horizontal_bar`, `vertical_bar`, `icon`, `icon_and_text`, `arc`
|
||
|
|
|
||
|
|
A right-click on the widget opens a popup where you can choose a sink/source:
|
||
|
|
|
||
|
|
|
||
|
|
Left click toggles mute and middle click opens a mixer ([pavucontrol](https://freedesktop.org/software/pulseaudio/pavucontrol/) by default).
|
||
|
|
|
||
|
|
### Features
|
||
|
|
|
||
|
|
- switch between sinks/sources by right click on the widget;
|
||
|
|
- more responsive than previous versions of volume widget, which were refreshed once a second;
|
||
|
|
- 5 predefined customizable looks;
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
Clone the repo under **~/.config/awesome/** and add widget in **rc.lua**:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
local volume_widget = require('awesome-wm-widgets.volume-widget.volume')
|
||
|
|
...
|
||
|
|
s.mytasklist, -- Middle widget
|
||
|
|
{ -- Right widgets
|
||
|
|
layout = wibox.layout.fixed.horizontal,
|
||
|
|
...
|
||
|
|
-- default
|
||
|
|
volume_widget(),
|
||
|
|
-- customized
|
||
|
|
volume_widget{
|
||
|
|
widget_type = 'arc'
|
||
|
|
},
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that widget uses following command the get the current volume: `amixer -D pulse sget Master`, so please make sure that it works for you, otherwise you need to set parameter `device = 'default'`.
|
||
|
|
|
||
|
|
### Shortcuts
|
||
|
|
|
||
|
|
To improve responsiveness of the widget when volume level is changed by a shortcut use corresponding methods of the widget:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
awful.key({ modkey }, "]", function() volume_widget:inc(5) end),
|
||
|
|
awful.key({ modkey }, "[", function() volume_widget:dec(5) end),
|
||
|
|
awful.key({ modkey }, "\\", function() volume_widget:toggle() end),
|
||
|
|
```
|
||
|
|
|
||
|
|
## Customization

||
