in reply to Awesome WM config: Lua Source Parse

Some alternatives - consider a map statement for the inner loop and consider a heredoc for the title. You could probably make the header separator a static too. Something like (not tested):
sub printSettings { my @groups = shift; my $sep = "=" x 60; foreach my $table (@groups) { foreach my $info (@$table) { my $cnt = 1; print <<EOF; $sep $info->[0] $sep EOF print map { sprintf "%5s. %-25s %-5s $info->[1]\n", $cnt +++, $_;} sort keys {$info->[1]}; } } }

    Thank you space_monk. I had thought of using map, but decided against it. In reading this reply to a previous post of mine Re: Efficiency of map vs. more verbose basic/fundamental code it is suggested that map is better used to create a new list based on modified elements of a previous one, rather than in the printing of a list. I will definitely look into a heredoc for the title, though. I like the way you did that. Thank you again for your suggestions.
