* 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 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.

  These are some xmobar [[file:doc/screenshots][screenshots]] using the author's configuration:

  Check [[./changelog.md][the change log]] for our release history.  We also have an IRC
  channel, ~#xmobar~ at [[ircs://irc.libera.chat][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

  #+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=.

*** 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~ and ~Pango~.

*** Using xmobar in Wayland with swaybar

    In text mode, xmobar can be told to ouput its information using
    pango markup for colors, and it that way you can use it with
    swaybar.  Here's a minimal ~bar~ configuration for sway's
    configuration file:

    #+begin_src conf
      bar {
        status_command xmobar -TPango
        pango_markup enabled
      }
    #+end_src

  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...;-).
