in thread Find images regardless of filetype extension.

Compactness affects readability. And besides, you're counting declarations and braces as lines, if I put it on one line it doesn't mean it's a single statement... if you're looking for compactness, here goes:

I'll assume @files and @dirs are already declared then.
map {$d="$dir/$_";$r= -d $d?\@dirs:\@files;push @$r,$d;} grep {!/^\./} + readdir DIR;

Yes, this uses map in void context, but you want compactness, not efficiency :)

He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

    Ill give you that is compact!

    But I think, that

    • my @files = map { "$dir/$_" } grep { !/^\.{1,2}\z/ && -f "$dir/$_" } @tmp;
    is both compact but very clear and readable. On the otherhand,
    • map {$d="$dir/$_";$r= -d $d?\@dirs:\@files;push @$r,$d;} grep {!/^\./} readdir DIR;
    is compact and clever but not easily readable IMHO.

    On the other hand, I really like your use of the ternary and references. I would not have thought of using it like that. ++ ++ I think that is quite clever. Thanks for the snippet of code.

    Only one complaint, the way you wrote you regex it will skip any dot file. So .my-file would not be picked up.
