(Battery Widget) Unexpected symbol near { in rc.lua about awesome-wm-widgets

[streetturtle]

I've updated widgets recently to work with Awesome 4 - unfortunately it's not backward compatible with previous version of Awesome.
You can try this repo: https://github.com/streetturtle/AwesomeWM3#battery-widget but it's not so nice as for v.4 :) And In version 3 widgets are added following way:

local right_layout = wibox.layout.fixed.horizontal()
right_layout:add(wibox.widget.systray())
right_layout:add(separator)
right_layout:add(lunchMenuWidget)
right_layout:add(separator)
right_layout:add(mouse_battery_icon)

Please let me know if something is unclear.
I'll update the docs to make it more clear.

Thanks!
