#+title: Compiling xmobar from source
If you don't have =cabal-install= installed, you can get xmobar's source
code in a variety of ways:
- From [[http://hackage.haskell.org/package/xmobar/][Hackage]]. Just download the latest release from xmobar's hackage
page.
- From [[http://codeberg.org/xmobar/xmobar/][Codeberg]]. There are also tarballs available for every tagged
release on [[https://codeberg.org/xmobar/xmobar/releases][Codeberg's releases page]]
- From the bleeding edge repo. If you prefer to live dangerously, just
get the latest and greatest (and buggiest, I guess) using git:
#+begin_src shell
git clone git://codeberg.org/xmobar/xmobar
#+end_src
If you have cabal installed, you can now use it from within xmobar's
source tree:
#+begin_src shell
cabal install --flags="all_extensions"
#+end_src
There is also a =stack.yaml= file that will allow you to install the
xmobar executable with
#+begin_src shell
stack install
#+end_src
See the =stack.yaml= file for the enabled extensions. You can also pass
them to =stack= directly:
#+begin_src shell
stack install --flag xmobar:all_extensions
#+end_src
** Optional features
:PROPERTIES:
:CUSTOM_ID: optional-features
:END:
You can configure xmobar to include some optional plugins and
features, which are not compiled by default. To that end, you need
to add one or more flags to either the cabal install command or
the configure setup step, as shown in the examples above.
Extensions need additional libraries (listed below) that will be
automatically downloaded and installed if you're using cabal
install. Otherwise, you'll need to install them yourself.
- =with_dbus= Enables support for DBUS by making xmobar to publish a
service on the session bus. Requires the [[http://hackage.haskell.org/package/dbus][dbus]] package.
- =with_threaded= Uses GHC's threaded runtime. Use this option if xmobar
enters a high-CPU regime right after starting.
- =with_cairo= Antialiased fonts via Cairo/Pango. For fonts, you can use
their fontconfig name, e.g
#+begin_src haskell
font = "Iosevka Medium 10"
font = "DejaVu Sans Mono italic 9"
#+end_src
Or to have fallback fonts, just separate them by commas:
#+begin_src haskell
font = "Open Sans,WenQuanYi Zen Hei 9"
#+end_src
For backwards compatibility, font names with `xft:` are also supported.
#+begin_src haskell
font = "xft:DejaVu Sans Mono-10"
#+end_src
- =with_xrender= Enables the main bar background alpha parameter. Requires
the [[http://hackage.haskell.org/package/X11-xft/][X11-xft]] package.
- =with_mpd= Enables support for the [[http://mpd.wikia.com/][MPD]] daemon. Requires the [[http://hackage.haskell.org/package/libmpd/][libmpd]]
package.
- =with_mpris= Enables support for MPRIS v1/v2 protocol. Requires the
[[http://hackage.haskell.org/package/dbus][dbus]] and [[http://hackage.haskell.org/package/text][text]] packages.
- =with_inotify= Support for inotify in modern Linux kernels. This
option is needed for the MBox and Mail plugins to work. Requires the
[[http://hackage.haskell.org/package/hinotify/][hinotify]] package.
- =with_nl80211= Support for wireless cards on Linux via nl80211 (all
upstream drivers). Enables the Wireless plugin. Requires [netlink] and
[cereal] packages.
- =with_iwlib= Support for wireless cards via Wext ioctls (deprecated).
Enables the Wireless plugin. No Haskell library is required, but you
will need the [[http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html][iwlib]] C library and headers in your system (e.g.,
install =libiw-dev= in Debian-based systems or =wireless_tools= on
Arch Linux). Conflicts with =with_nl80211=.
- =with_alsa= Support for ALSA sound cards. Enables the Volume plugin.
Requires the [[http://hackage.haskell.org/package/alsa-mixer][alsa-mixer]] package. To install the latter, you'll need
the [[http://packages.debian.org/stable/libasound2-dev][libasound]] C library and headers in your system (e.g., install
=libasound2-dev= in Debian-based systems).
- =with_datezone= Support for other timezones. Enables the DateZone
plugin. Requires [[http://hackage.haskell.org/package/timezone-olson][timezone-olson]] and [[http://hackage.haskell.org/package/timezone-series][timezone-series]] package.
- =with_xpm= Support for xpm image file format. This will allow loading
.xpm files in =<icon>=. Requires the [[http://cgit.freedesktop.org/xorg/lib/libXpm][libXpm]] C library.
- =with_uvmeter= Enables UVMeter plugin. The plugin shows UV data for
Australia.
- =with_weather= Support to display weather information. Enables Weather
plugin.
- =all_extensions= Enables all the extensions above.
