* About
Xmobar is a minimalistic status bar. It was originally designed and
implemented by Andrea Rossato to work with [[http://xmonad.org][xmonad]], but it is actually
usable with any window manager.
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.
These are some xmobar [[file:doc/screenshots][screenshots]] using the author's configuration:
[[file:doc/screenshots/xmobar-top.png]]
[[file:doc/screenshots/xmobar-bottom.png]]
[[file:doc/screenshots/xmobar-exwm.png]]
This is the [[./changelog.md][changelog]] for recent releases.
* Installation
** From your Systems 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://github.com/jaor/xmobar/issues/461][this issue]] for more information.
See [[file:doc/compiling.org][compiling]] 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
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=.
** Signal Handling
xmobar reacts to SIGUSR1 and SIGUSR2:
- After receiving SIGUSR1 xmobar moves its position to the next screen.
- After receiving SIGUSR2 xmobar repositions itself on the current
screen.
* Configuration and Further Links
- If you want to jump straight into configuring xmobar, head over to the
[[./doc/quick-start.org][quick-start]] guide.
- If you want to get a detailed overview of all available plugins and
monitors, visit the [[./doc/plugins.org][plugins]] file.
- If you want to know how to contribute to the xmobar project, check out
[[contributing.org][contributing]].
- If you want to write your own plugins, see [[./doc/write-your-own-plugin.org][write-your-own-plugin]].
- To understand the internal mysteries of xmobar you may try reading
[[https://wiki.haskell.org/X_window_programming_in_Haskell][this tutorial]] on X Window Programming in Haskell.
* Authors and credits

0.11.1. Since then, it is maintained and developed by [[https://jao.io][jao]], with the help

** Thanks
*Andrea Rossato*:
Thanks to Robert Manea and Spencer Janssen for their help in
understanding how X works. They gave me suggestions on how to solve many
problems with xmobar.
Thanks to Claus Reinke for make me understand existential types (or at
least for letting me think I grasp existential types...;-).
*jao*:
Thanks to Andrea for creating xmobar in the first place, and for giving
me the chance to contribute.
