I'm looking for a way to get a perl one-liner print x lines of <> before a regex match. My initial, unfulfilling attempt goes like this .. (x is 4 here)

 perl -F/\\n/ -0ane 'for (0..$#F) {$c++; push @c, --$c if $F[$_]=~/regex/;} END{for (@c) {print join "\n", @F[($_-4)..$_]; print "\n---\n"}}' file

kinda works albeit kinda long. I'm interested in how you'd tackle this perl-oblem .. so, any ways of shortening/simplyfying it?
