Installation

1. Clone this repositry:

   git clone https://gist.github.com/f1a3d486e0ef92fad01020a81e47769e.git ~/.config/awesome/sushiwidget

2. Download sushi image

   wget -O sushi.png https://github.com/twitter/twemoji/raw/gh-pages/72x72/1f363.png

3. Create new wibox and insert sushiwidget!

   local sushiwidget = require('sushiwidget/sushiwidget')
   local sushi = sushiwidget({
     image = awful.util.getdir('config') .. '/sushi.png'
   })
   
   local sushiwibox = {}
   
   for s = 1, screen.count() do
     local sushilayout = wibox.layout.fixed.horizontal()
     sushilayout:add(sushi)
   
     sushiwibox[s] = awful.wibox({ position = 'bottom', height = 36, screen = s })
     sushiwibox[s]:set_widget(sushilayout)
   end
