This is a desktop information bar intended for use with XMonad and similar window managers. It is similar in spirit to xmobar; it is different in that it gives up some simplicity for a reasonable helping of eye candy. This bar is based on GTK+ (via gtk2hs) and uses fancy graphics where doing so is reasonable and useful. Example:

The bar is configured much like XMonad. It uses ~/.config/taffybar/taffybar.hs as its configuration file. This file is just a Haskell program that invokes the real main function with a configuration object. The configuration file basically just specifies which widgets to use, though any arbitrary Haskell code can be executed before the bar is created.

There are some generic pre-defined widgets available:

• Graph (modeled after the graph widget in Awesome)
• Vertical bar (also similar to a widget in Awesome)
• Periodically-updating labels, graphs, and vertical bars

There are also several more specialized widgets:

• Battery widget
• Volume widget
• Network activity
• Textual clock
• Freedesktop.org notifications (via dbus)
• MPRIS1 and MPRIS2 widgets
• Weather widget
• Workspace, Window and Layout switchers
• System tray
• Freedesktop.org menu
