Xmobar is a minimalistic status bar. It was originally designed and
implemented to work with [[http://xmonad.org][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 [[http://tuomov.iki.fi/software/][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 [[./changelog.md][the change log]] for our release history. We also have an IRC
channel, ~#xmobar~, at [[ircs://irc.libera.chat][Libera]].
* Installation
:PROPERTIES:
:CUSTOM_ID: installation
:END:
** 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
#+begin_src shell
pacman -S xmobar
#+end_src
- Debian/Ubuntu based
#+begin_src shell
apt install xmobar
#+end_src
- OpenSUSE
#+begin_src shell
zypper install xmobar
#+end_src
- Void Linux
#+begin_src shell
xbps-install xmobar
#+end_src
- Gentoo
#+begin_src shell
emerge --ask xmobar
#+end_src
** Using cabal-install
Xmobar is available from [[http://hackage.haskell.org/package/xmobar/][Hackage]], and you can install it using
=cabal-install=:
#+begin_src shell
cabal install xmobar
#+end_src
Starting with version 0.35.1, xmobar now requires at least GHC version
8.4.x. to build. See [[https://codeberg.org/xmobar/xmobar/issues/461][this issue]] for more information.
See [[file:doc/compiling.org#optional-features][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:
#+begin_src shell
cabal install xmobar --flags="all_extensions"
#+end_src
** From source
See [[file:doc/compiling.org][compiling]].
* Running xmobar
** Running xmobar with a configuration file
You can run xmobar with:
#+begin_src shell
xmobar /path/to/config &
#+end_src
or
#+begin_src shell
xmobar &
#+end_src
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 [[file:quick-start.org][the quick start guide]] and [[file:plugins.org][the plugins documentation]].
** Writing your own xmobar in Haskell
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 [[http://xmonad.org][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 at
[[file:doc/using-haskell.org][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 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
(so, for instance, you could pipe xmobar's output to a Wayland
application, such as swaybar.)
To run xmobar in text mode, either pass the =-T= flag to its
invocation:
#+begin_src shell
xmobar -T /path/to/config &
#+end_src
or set the parameter =textOutput= to True in its configuration. You
can also specify the format of color escapes, for instance,
omitting them altogether with ~Plain~:
#+begin_src shell
xmobar -TPlain /path/to/config &
#+end_src
Other options are ~Ansi~, ~Pango~, and ~Swaybar~.
** Using xmobar in Wayland with swaybar or waybar
In text mode, xmobar can be told to ouput its information using
pango markup for colors and fonts, and it that way you can use it
with swaybar or waybar, if you don't have actions or boxes in your
template. Here's a minimal ~bar~ configuration for sway's
configuration file:
#+begin_src conf
bar {
status_command xmobar -TPango
pango_markup enabled
}
#+end_src
In case you want to use boxes around text or click actions in your
template, you can use instead the format ~Swaybar~, which supports
both. This output format follows the JSON /swaybar-protocol/
defined by swaybar. Configure it simply with:
#+begin_src conf
bar {
status_command xmobar -TSwaybar
}
#+end_src

- If you want to get a detailed overview of all available plugins and
monitors, visit the [[./doc/plugins.org][plugins index]].
- [[./doc/window-managers.org][Interfacing with window managers]] describes plugins and extensions
for interacting with xmobar from your window manager.

to create your monitors, see [[https://codeberg.org/jao/xmobar-config][this repo at jao/xmobar-config]].

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...;-).
