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.

[Corion]: ambrus: Yeah, they wrote articles themselves, but I think the TeX version of the articles was sometimes produced by the secretaries
[ambrus]: Corion: no, these days like half of the times the professors write the articles in TeX (with formatting that's mostly acceptible but not usually good), and the other half of the time it's people who are already co-authors of the article that write it
