It is similar in spirit to [xmobar][], but it differs in that it gives +up some simplicity for a reasonable helping of [GTK 3][] eye candy. + +Taffybar also supports running under Wayland via `gtk-layer-shell`. Wayland +support is currently compositor-specific for some widgets, with Hyprland +workspaces, windows, and layout widgets available. Many widgets still rely on +X11/EWMH, so check the widget docs and examples (including +`example/taffybar-wayland.hs`) for what works on your setup.
