>xmonad calls the logHook with every internal state update, which is
 useful for (among other things) outputting status information to an
 external status bar program such as xmobar or dzen.  DynamicLog
 provides several drop-in logHooks for this purpose, as well as
 flexible tools for specifying your own formatting.

</P

 (<TT

>dynamicLog</A
></TT
> or <TT
><A HREF="XMonad-Hooks-DynamicLog.html#v%3AdynamicLogXinerama"

</PRE
><P
>For more flexibility, you can also use <TT

>dynamicLogWithPP</A
></TT
> and supply
 your own pretty-printing format (by either defining one from scratch,
 or customizing one of the provided examples).
 For example:
</P
><PRE
>    -- use sjanssen's pretty-printer format, but with the sections
    -- in reverse
    logHook = dynamicLogWithPP $ sjanssenPP { ppOrder = reverse }
</PRE
><P
>Note that setting the <TT
>logHook</TT
> only sets up xmonad's output; you
 are responsible for starting your own status bar program (e.g. dzen
 or xmobar) and making sure xmonad's output is piped into it
 appropriately, either by putting it in your <TT
>.xsession</TT
> or similar
 file, or by using <TT
>spawnPipe</TT
> in your <TT
>main</TT
> function, for example:
</P
><PRE
> import XMonad.Util.Run   -- for spawnPipe and hPutStrLn

 main = do
     h &lt;- spawnPipe &quot;xmobar -options -foo -bar&quot;
     xmonad $ defaultConfig {
       ...
       logHook = dynamicLogWithPP $ defaultPP { ppOutput = hPutStrLn h }
</PRE
><P
>If you use <TT
>spawnPipe</TT
>, be sure to redefine the <TT
><A HREF="XMonad-Hooks-DynamicLog.html#v%3AppOutput"
>ppOutput</A
></TT
> field of
 your pretty-printer as in the example above; by default the status
 will be printed to stdout rather than the pipe you create.
</P
><P
>Even if you don't use a statusbar, you can still use
 <TT
><A HREF="XMonad-Hooks-DynamicLog.html#v%3AdynamicLogString"
>dynamicLogString</A
></TT
> to show on-screen notifications in response to
 some events. For example, to show the current layout when it
