I prefer
sub printlog {
print LOG @_ unless $nolog;
}
printlog "======== done =========\n";
to
print LOG "======== done =========\n" unless $nolog;
as it makes for less clutter. It is also beneficial in
that, with a little more work, $nolog doesn't
have to pollute the namespace.
BEGIN {
my $nolog = 0;
sub setlog {
$nolog = shift;
}
sub printlog {
print LOG @_ unless $nolog;
}
}
setlog 1;
printlog "======== done =========\n";
I like to generalise this functionality to handle debug/production screen output and/or
log file output.
