xmobar, a minimalistic status bar

Xmobar is a minimalistic status bar. It was originally designed and implemented to work with xmonad, but it is actually usable with any window manager in X11 and also (via its text output mode) Wayland.

Xmobar was inspired by the Ion3 status bar, and supports similar features, like dynamic color management, icons, output templates, and extensibility through plugins. It is also able to write to standard output, in a variety of formats.

Check the change log for our release history. We also have an IRC channel, #xmobar, at Libera.

Installation

From your system’s package manager

Xmobar is probably available from your distributions package manager! Most distributions compile xmobar with the all_extensions flag, so you don’t have to.

• Arch Linux

  pacman -S xmobar
      

• Debian/Ubuntu based

  apt install xmobar
      

• OpenSUSE

  zypper install xmobar
      

• Void Linux

  xbps-install xmobar
      

• Gentoo

  emerge --ask xmobar
      

Using cabal-install

Xmobar is available from Hackage, and you can install it using cabal-install:

cabal install xmobar

Starting with version 0.35.1, xmobar now requires at least GHC version 8.4.x. to build. See this issue for more information.

See here for a list of optional compilation flags that will enable some optional plugins. For instance, to install xmobar with all the bells and whistles (this is probably what you want), use:

cabal install xmobar --flags="all_extensions"

From source

See compiling.

Running xmobar

Running xmobar with a configuration file

You can run xmobar with:

xmobar /path/to/config &

or

xmobar &

if you have the default configuration file saved as $XDG_CONFIG_HOME/xmobar/xmobarrc (defaulting to ~/.config/xmobar/xmobarrc), or ~/.xmobarrc.

All the available command line switches and configuration parameters are described in the quick start guide and the plugins index.

Writing your own xmobar in Haskell

As shown above, one can use xmobar as a regular program, via its configuration file, without having to write any code. It also is possible to install xmobar as a library and use it to write your own xmobar using Haskell instead of using a configuration file. (This is very similar to how xmonad works.) That gives you the ability of using Haskell and its libraries to extend xmobar to your heart’s content. If you are a programmer, take a look here to learn more.

Running xmobar in text mode

By default, xmobar will run as an X11 application, in a docked window, but it is possible to redirect xmobar’s output to the standard output, optionally with color escape sequences. In this mode, xmobar can be run inside a terminal o console, or its output piped to other applications, and there is no need for an X11 display. See Running xmobar in text mode for details. Using this mode, you could pipe xmobar’s output to, say, swaybar, and use it in wayland.

Andrea wants to thank Robert Manea and Spencer Janssen for their help in understanding how X works. They gave him suggestions on how to solve many problems with xmobar. He also thanks Claus Reinke for making him understand existential types (or at least for letting him think he grasps existential types…;-).
