FVWM Perl Library

FVWM pioneered a concept of modules that extend a window manager. There is now a Perl API for the module protocol.

Useful to customize the dynamical user's needs:

• Create a monitoring applet (shows a whether, CPU temperature)
• Construct panels with conditional parts
• Constract dynamical menus (say, display window list)
• Event handlers in Perl (immediately close unwanted windows)

use FVWM::Module;

my $module = new FVWM::Module;  
my $tracker = $module->track('PageInfo');
$tracker->observe(sub {
	my ($module, $tracker, $info) = @_;
	$module->send("Exec echo '($info->{page_nx}, $info->{page_ny})' | osd_cat -A center -");
});

$module->eventLoop;
