A widget for the Awesome Window Manager to display power devices with UPower and DBus

This widget uses the upower_dbus library.

Requirements

In addition to the requirements listed in the rockspec file, you will need the Awesome Window Manager and UPower (for more information about this, see the upower_dbus documentation).

You will also need the DBus headers (dbus.h) installed. For example, Debian and Ubuntu provide the DBus headers with the libdbus-1-dev package, Fedora, RedHad and CentOS provide them with the dbus-devel package, while Arch provides them (alongside the binaries) with the libdbus package.

Installation

Using Luarocks

Probably, the easiest way to install this widget is to use luarocks:

luarocks install upower_widget

You can use the --local option if you don't want or can't install it system-wide

This will ensure that all its dependencies are installed.

A note about ldbus

This module depends on the ldbus module that provides the low-level DBus bindings

luarocks install --server=http://luarocks.org/manifests/daurnimator \
    ldbus \
    DBUS_INCDIR=/usr/include/dbus-1.0/ \
    DBUS_ARCH_INCDIR=/usr/lib/dbus-1.0/include

As usual, you can use the --local option if you don't want or can't install it system-wide.

From source

Alternatively, you can copy the upower_widget.lua file in your ~/.config/awesome folder. You will have to install all the dependencies manually though (see the rockspec file for more information).

Configuration

The widget displays power icons that are searched in the folders defined in the table beautiful.upower_icon_theme_dirs with extensions defined in the table beautiful.upower_icon_extensions. The default is to look into "/usr/share/icons/Adwaita/scalable/devices/" and "/usr/share/icons/Adwaita/scalable/status/"for icons whose extension is "svg". Note that the directory paths must end with a slash and that the extensions must not contain a dot. The icons are searched using Awesome's awful.util.geticonpath function.

You can specify a GUI client to be launched when the widget is right-clicked. This can be done by changing the gui_client field of the widget. The default is to have no client. For example, you could use the XFCE4 Power Manager or the GNOME one.

Mouse controls

When the widget is focused:

• Right button: launches GUI client (defined by the gui_client field; defaults to the empty string, so nothing will happen)

Tooltip

A tooltip with the current device power status shown.

Usage

Add the following to your ~/.config/awesome/rc.lua:

Require the module:

-- require *after* `beautiful.init` or the theme will be inconsistent!
local power = require("power_widget")
-- override the GUI client.
power:init()
power.gui_client = "xfce4-power-manager"

Add the widget to your layout:

• Awesome 3.5.x rc.lua

right_layout:add(power)

• Awesome 4.x rc.lua

    -- Add widgets to the wibox
    s.mywibox:setup {
        layout = wibox.layout.align.horizontal,
        { -- Left widgets
            layout = wibox.layout.fixed.horizontal,
            s.mytaglist,
            s.mypromptbox,
        },
        s.mytasklist, -- Middle widget
        { -- Right widgets
            layout = wibox.layout.fixed.horizontal,
            -- other widgets
            power,
        },
    }
