CPU widget

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

When the load is more than 80% the graph becomes red. You can easily customize the widget by changing colors, step width, step spacing, width and interval.

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.

Installation

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

require("awesome-wm-widgets.cpu-widget.cpu-widget")
...
s.mytasklist, -- Middle widget
	{ -- Right widgets
    	layout = wibox.layout.fixed.horizontal,
		...
		cpu_widget,
