[Xmonad] State information, workspace names and "emptyness" indicator

4 Jun 2007

      Hi,

below you'll find a _rather hackish_ approach to display state information
with xmonad. See the comments in the script to get it running.

Here is a shot how it could look like, note the upper left corner:

Script and instructions:

#!/usr/bin/perl
# statedump.pl - beware, hackish solution
#
# (c) 2007 by Robert Manea <rob dot manea at gmail dot com>
# dump xmonad state in a readable format
#
# Usage:
# ------
# Uncomment the line reading "withWindowSet (io . hPrint stderr)"
# in xmonad's Operations.hs. This will enable a state dump.
#
# start xmonad like this:
# xmonad 2>&1 | statedump.pl | dzen2 -w 300 -ta l
#
# Workspaces containing windows have an * prefix
# the current workspace is enclosed in [ ]
#

use strict;
use warnings;

#----------------------------------------------------------------------
# set the names of the workspaces
# if no name is set, the workspace
# number will be displayed

my %ws2name = ( 
	0 => "dev",
	1 => "mail", 
	2 => "web", 
	3 => "comm", 
	4 => "ham",
	5 => "tmp"
);

#----------------------------------------------------------------------
my $fr=0;
$|=1;

while(<>) {
	my @s = split /Workspace/;
	$s[1] =~ /tag\s=\s+W\s([0-9]),/;
	my $cws = $1;

	for(sort @s) {
		my @f = /{tag\s=\s+W\s([0-9]),.*stack\s=\s+(.*)/;
		my $ws = $f[0]; my $emp = $f[1];

		$fr++;
		if($fr < @s) {
			print "*" if($emp !~ /Empty/);
			if($ws eq $cws) {
				$ws2name{"$cws"} ? print '[', $ws2name{"$cws"}, '] ' : print '[', $cws+1, '] ';
			} else {
				$ws2name{"$ws"} ? print $ws2name{"$ws"}, ' ' : print $ws+1, ' ';
			}
		}

	}
	$fr=0;
	print "\n";
}

__END

Bye, Rob.
