Hi,

so, thanks to Spencer, who gave me the right directions, I came up
with a nice working solution, after a small (well, not that small) API
change.

I've just added a PipeReader plugin, already pushed in my darcs repo:
http://gorgias.mine.nu/repos/xmobar/

To use it add such command in the command list of your configuration:
Run PipeReader "/home/andrea/.xmonad.log" "xmonad"

and, in the template:
%xmonad%

Then, in your .xprofile, something like:

PIPE=$HOME/.xmonad.log
rm -f $PIPE
PATH=${PATH}:/sbin mkfifo -m 600 $PIPE
[ -p $PIPE ] || exit
xmobar &
xmonad > $PIPE

Let me know what you think.
Cheers,
Andrea
