Different background color for each taglist item AwesomeWM

Question

how can I set a different background color for each taglist item? I know I have to use widget_template but I don't know how, I'm on awesomeWM 4.3

Answer 1

Suppose you have tags named with keys of this colors table:

colors = {
   term = "#FF0000",
   www = "#00FF00",
   divers = "#0000FF",
   travail = "#FF0000",
   default = "#00FF00"
}

and maybe some others.

With widget_template, (you've cited), within awful.widget.taglist:

widget_template = {
       {
          id     = 'text_role',
          widget = wibox.widget.textbox
        },
        id     = 'bg',
        widget = wibox.container.background,
        create_callback = function(self, t, index, tagsList)
           self.bg = colors[t.name] or colors.default
        end,
    }
