Volume widget

Volume widget based on amixer (is used for controlling the audio volume) and 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 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:

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:

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

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

Generic parameter

Name	Default	Description
mixer_cmd	pavucontrol	command to run on middle click (e.g. a mixer program)
step	5	How much the volume is raised or lowered at once (in %)
widget_type	icon_and_text	Widget type, one of horizontal_bar, vertical_bar, icon, icon_and_text, arc
device	pulse	Select the device name to control

Depends on the chosen widget type add parameters from the corresponding section below:

icon parameters

Name	Default	Description
icon_dir	./icons	Path to the folder with icons

Note: if you are changing icons, the folder should contain following .svg images:

• audio-volume-high-symbolic
• audio-volume-medium-symbolic
• audio-volume-low-symbolic
• audio-volume-muted-symbolic

icon_and_text parameters

Name	Default	Description
icon_dir	./icons	Path to the folder with icons
font	beautiful.font	Font name and size, like Play 12

arc parameters

Name	Default	Description
thickness	2	Thickness of the arc
main_color	beautiful.fg_color	Color of the arc
bg_color	#ffffff11	Color of the arc's background
mute_color	beautiful.fg_urgent	Color of the arc when mute

horizontal_bar parameters

Note: I didn't figure out how does the forced_height property of progressbar widget work (maybe it doesn't work at all), thus there is a workaround with margins.
