CPU widget

This widget shows the average CPU load among all cores of the machine:

How it works

To measure the load I took Paul Colby's bash script and rewrote it in Lua, which was quite simple. So awesome simply reads the first line of /proc/stat:

$ cat /proc/stat | grep '^cpu '
cpu  197294 718 50102 2002182 3844 0 2724 0 0 0

and calculates the percentage.

Customization

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

Name	Default	Description
width	50	Width of the widget
step_width	2	Width of the step
step_spacing	1	Space size between steps
color	beautiful.fg_normal	Color of the graph
enable_kill_button	false	Show button which kills the process
process_info_max_length	-1	Truncate the process information. Some processes may have a very long list of parameters which won't fit in the screen, this options allows to truncate it to the given length.
timeout	1	How often in seconds the widget refreshes

Example

cpu_widget({
    width = 70,
    step_width = 2,
    step_spacing = 0,
    color = '#434c5e'
})

The config above results in the following widget:

Installation

Clone/download repo and use widget in rc.lua:

local cpu_widget = require("awesome-wm-widgets.cpu-widget.cpu-widget")
...
s.mytasklist, -- Middle widget
	{ -- Right widgets
    	layout = wibox.layout.fixed.horizontal,
		...
		-- default
		cpu_widget(),
		-- or custom
		cpu_widget({
            width = 70,
            step_width = 2,
            step_spacing = 0,
            color = '#434c5e'
        })
		...
