Notes
I liked this dot, therefore I ported to 4.x, cleaned and parameterized.
Copy/paste it in your ~/.config/awesome and declare it in rc.lua:
local clock = require("clock")
It takes a table as input, which arguments are: screen, font (only string name) width, weight, x, y, bg (hex color string).
Call new in awful.screen.connect_for_each_screen function:
awful.screen.connect_for_each_screen(function(s)
-- Clock
clock.new({ screen = s })
...
and you’re done.
