waybar workspaces to display occupied and focused

[rvcgit]

hello,
i ve been playing with vivarium past few weeks and though i am not a code guy, i ve been toying with creating scripts to display workspaces in waybar.
i could set it up with "on-click" config to change fore ground color to display this is the focused workspace. [ i am using ydotool key to bind the command for on-click option in waybar config ]
i wish to set foreground color in waybar workspace so i know which workspace is occupied [ not in current focus ]. is there a commandline which i can use in a bash script to show occupied workspace ?
thanks in advance !

further, tasks not being displayed in waybar [ as it displays in other wayland compositors ]
